  • Sea levels will rise because warmer water expands.
  • Sea levels will rise as glaciers and ice caps continue to melt, moving water from land into the oceans.



In 2000, it was claimed the ice caps would be gone by 2010, and there would be drastic sea level rises around the world, flooding coastal cities. It hasn't happened.
If the caps did indeed melt, it could happen, but so far the dire predictions have not occurred.

What will happen if global warming continues?

Many things can happen if Global Warming continues: . Heat waves and the resulting deaths . Loss of crops and the resulting famines . Glaciers and the ice caps of Greenland and Antarctica meltingand the resulting flooding of coastal lands, cities, and low-lyingcountries . Increased and more savage storm activity, especially coastalstorms, high tides, and storm surges with the resulting threats ofsalt-water flooding of croplands and erosion . Loss of habitat for all kinds of bird, insect, marine, andanimal life, including man, with the resulting need to move, adapt,or die. Countries will get warmer and many areas now used for growing cropswill become desert. Sea levels will rise and many low lying areaswill be flooded. Millions of people all over the world will becomerefugees, desperately seeking new homes and new lands where theycan have food and water. A: The IPCC 2007 syntheses report projects a number of both positiveand negative impacts associated with climate change and sea levelrise. These are summarized in the "IPCC Impacts of Climate Change"link in the related links section. . Many island nations, such as Bangladesh and other continentallow lying areas will be inundated by a rising sea, displacingmillions of people, and creating a global refugee crisis. . Disruptions to climatic systems like the thermohalinecirculation (ocean currents) may cause cooling and drying in somelocations. For example, the Gulf Stream which keeps Europe warm andhabitable may stop, as has happened in the past, resulting in areturn of now balmy European climate to something similar toSiberia. . An advance of tropical diseases into higher latitudes. Diseaseslike malaria are spread by warm loving mosquitoes, which canmigrate further in a warmer climate, and may result in world widepandemics. . Acidification of the oceans associated with increases CO2 inthe atmosphere may result in a massive die off of fish and othermarine life, resulting in global ecological collapse and massivedepletion of crucial food stocks. . Agricultural land which now grows crops will become desert,forcing millions of people to seek food elsewhere. . Sources of water for agricultural and domestic use will dryup. . The economies of many countries will collapse.

Why does global warming happen?

When light from the Sun enters our atmosphere it gets converted to heat which gets trapped by greenhouse gases such as carbon dioxide, methane, and water vapor. By burning fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, we have been adding extra greenhouse gas to the atmosphere. Over time the average temperature of the Earth increases. There are various reasons why global warming happens. The mainreason is emission of carbon dioxide into the atmosphere whichtraps the heat into the environment.

Will global warming happen?

Global warming is already happening. We are already seeing glaciers retreating, polar ice melting, hottest year records regularly being broken. Scientists have been hoping that the temperature will not rise more than 2 degrees Celsius, but many are saying it's already too late for that.

What will happen to the beaches if global warming continues?

One anticipated effect of global climate change is an anticipatedrise in sea level. This will place the beaches closer to you if youlive inland. The specific changes in any particular beach will bedue to changes in the topography and currents in the new arae aswell as the wind and weather conditions. This means no specificchanges can be predicted.

What will happen if global warming happens?

One of the primary issues concerns sea level rise. There is enough ice locked in Greenland to raise ocean levels 20 feet. Although it would be centuries before Antarctica would melt, there is sufficient ice piled on that continent to raise ocean levels 200 feet. These sea level rises would be a major concern for coastal areas. Many parts of the world will grow hotter and drier, with some places likely becoming largely uninhabitable. Many areas used for food crops would be abandoned. A few locales around the world would receive more rainfall, and could offset a portion of the expected shortages. Tropical diseases would be expected to spread to more northern and southern latitudes. Although the frequency of storms would not be expected to change, the ferocity of tropical hurricanes should increase with the greater heat to drive them.

What will happen to glaciers if global warming continues?

If global warming continues, then glaciers, which are like riversof ice, will continue to melt and finally disappear. Many of theworld's great rivers get water from the spring melting of glaciers,so if glaciers vanish, the rivers and the people who rely on them,will be threatened.

How quickly will global warming happen?

Global warming will happen less than 10 years . Global Warming is already happening but in the future it is going to get worse. Global warming is a major event that could change everything about the earth.

Why is global warming happening?

Global warming is happening because of the two human activities of deforestation (cutting down forests) and burning fossil fuels (coal, oil and natural gas). Global warming is caused by human beings who have invented suchthings as cement, electric power, internal combustion engines andfurnaces and water heaters which use oil or gas as fuels. Cement is made by burning limestone, a process whichgenerates so much carbon dioxide gas (CO2) that it has become oneof the major pollutants of the Earth's atmosphere. Then the cementis used to make concrete to create huge and ever-growing citieswith their associated urban infrastructure such as buildings,tunnels, roads, railways, sea ports, airports, etc. Electric power does not arise naturally: it must always begenerated. Apart from the relatively small amount of electricitythat is currently generated using river dams and waterfalls orusing wind-generators, seawater wave-generators or solar cells, oneof the main ways to generate electric power at present is to burnfossil-based fuels such as coal, oil or gas. Such fuel burning isanother major source of pollution of the Earth's atmosphere. Human beings use internal combustion engines in vehiclessuch as cars, trucks, trains, ships and airplanes to travel about,both within and between those cities. They also use furnaces andwater heaters , which use oil or gas as fuels, to heat thebuildings in those cities. Even air conditioning systems that are used to cool buildings must use electricity, as must electric lighting and all the computer and communicationssystems we now use. There are four main factors: . The production of cement to make concrete produces a massiveamount of pollution, mainly carbon dioxide (CO2), which goesstraight into the Earth's atmosphere. . The burning of fossil-based fuels - both to generateelectricity and to fuel the internal combustion engines in cars,trucks, ships and airplanes - produces a massive amount ofatmospheric pollution, not only carbon dioxide (CO2) but carbonmonoxide (CO) and various oxides of nitrogen (NOX). The CO and NOXproduced in internal combustion engines can be reduced considerablyby using cleaner fuels and catalytic converters in cars and trucksbut catalytic converters are not currently available for the jetengines as currently used in airplanes. Nevertheless the CO2, produced in vast quantities by allcoal-burning electricity generation stations and by all oil- orgas-based heating systems and fuel-burning engines, remains a majorproblem. Those two factors - the production of cement and the burning offossil fuels - create much more carbon dioxide pollution in ouratmosphere than the Earth's natural processes can remove. One ofthe main natural processes for removing carbon dioxide from theatmosphere depends on having large forests of trees because trees"breathe in" carbon dioxide and "breathe out" oxygen. . The area of natural forests on the Earth is being greatlyreduced by humans who destroy whole rain-forests by burning downthe trees to make big fields in which they can plant crops for useas food and fuel. That burning itself produces massive amounts ofatmosphere-polluting CO2. Unless this deforestation is stoppedthere will be too few trees left to convert even naturally-producedcarbon dioxide into oxygen. (All animals which breath in oxygenmust breathe out CO2 and that is the naturally-produced CO2.) . One consequence of creating massive cities with buildings,tunnels, roads, etc. is that all the concrete that must be used tocreate the urban infrastructure absorbs and stores the heat fromthe Sun. As a result the temperature within cities is significantlywarmer than in the surrounding countryside.

Is global warming happening?

Yes. Global warming is not just something scientists predict tohappen in the future - it is happening right now. The last tenyears were the warmest since instrumental records began in 1850. A: We have the evidence, But we just don't want to believe it. So itis happening, but you just don't want to believe it, like me.

What will happen in the future if current trends continue for global warming?

There are multiple models as to the projected effects of globalclimate change assuming current carbon emissions are not reduced. . One of the most catastrophic outcomes will be rising sea levelsdue to glacier, Greenland and Antarctic ice melts. This has thepotential to radically alter population dense coastlines and eveneliminate entire coastal/island nations. . Discrete changes in temperature over the long run may alsocontribute to and cause mass extinction events of millions ofspecies. . Other effects include acceleration in losses of arable landsand further pressure on irrigation and water supplies.

How is global warming raising the sea levels?

Global warming is the cause of rising sea levels because the warming makes the oceans expand, so the levels rise. Also the melting of land ice like ice caps and glaciers runs into the sea and raises the levels.

Is it true if global warming continues you will die?

If global warming continues unchecked then the world will getwarmer and warmer and yes, you will die, along with every otherliving thing on the earth. Another View. However, there has been no warming for 17 years. Whether this issimply a pause, remains to be seen. There have also been cooling trends, examples: North America has seen three straight years of very cold winters,and also cooler summers.

What will happen to Antarctica if global warming continues?

Antarctica will melt if the temperatures do rise, this will resultin a loss of many species of animals and a rise In the sea levels.Global Warming is NO joke, it is serious and is actually happening. Also, research for finding cures will be eliminated as there won'tbe enough land to experiment on meaning we might not find bettercures for diseases. (Irrelevant information)The Antarctic ice sheet is getting larger,not smaller. NASA admitted this. So logic says at this rate, itcontinues to grow.

How will global warming cause sea levels to rise?

As glacial ice melts it tends to end up in the oceans. Much of the arctic ice is already afloat, so its melting contributes very little to sea rise. There will be some rise due to thermal expansion of ocean water. However, Greenland bears enough ice to raise ocean levels close to 20 feet. Antarctica has enough ice to raise ocean levels 200 feet, though this ice is not expected to melt for centuries.

What obvious effect will continued global warming have?

Global warming means that average global temperatures are rising. However, this rise is sufficiently gradual that it is really only obvious to scientists, especially as it is interrupted by short term climatic variations and masked by regional variations. One effect that will become obvious to coastal dwellers, even within a single lifetime, will be rising sea levels. Sea levels are now predicted to rise by between 90 and 150 centimetres over the course of the present century. Many people will be able to remember the water level at a familiar place, and marvel just how much higher it has become. Other coastal areas are expected to be inundated, a very obvious sign of rising sea levels and therefore of global warming.

How high will the sea level be with global warming?

Greenland ice will raise ocean levels a little over 20 feet (about 7 meters). This ice will continue melting over the next hundred years. Antarctic ice, which probably won't melt for centuries to come, would raise ocean levels 200 feet (over 60 meters).

What will happen to the oceans if global warming continues?

If global warming continues . The oceans will continue to rise as the warmer waterexpands . The glaciers and ice caps will continue to melt, raising sealevels even further . Carbon dioxide from the atmosphere will continue to be absorbedinto the surface waters, making them more acidic. This damagescoral and the shells of many marine creatures, such as krill.

What will happen if the sea level rises because of global warming?

There are three key impacts of sea level rise. 1) INUNDATION (flooding): Many low lying countries will be under water, including large parts of the USA, UK, Holland, Bangladesh, and many Pacific Island countries. Note that it is likely that these effects will be delayed, giving the false impression that they are not as serious as might have been feared. This is because, before the sea level begins to visibly rise, the water level has to equalise globally, that is, the sea water must penetrate and fill every void, hollow and porous body of soil/rock it encounters. Caverns, cave systems, lava tubes, 'cenotes', underground lakes and rivers etc., all must be filled before the waters can rise. Once this process is complete, however, sea level rise will suddenly gain momentum, as there will be nowhere else for the water to go. that is when we shall see coastal waters rise at vertiginous speed, especially, on a fairly localised scale, during full moon and high tide. 2) UNDERMINING (weakening by fluid penetration of porous rocks and soils): As water infiltrates soils and minerals it will begin to dissolve some of the matrices that hold together particles in soils and sedimentary rocks, like aggregates, breccias, mudstones, siltstones, sandstones, limestone etc. As a result of these unevenly distributed weakening of the rock and soils, whole areas of the surface will become unstable, though not necessarily visibly so, as these infiltrations may begin at great depths and progress upwards and outwards, as the sea penetrates deeper inland. The heavier the construction burden on the rock/soil the more likely the sudden, catastrophic collapse of roads, bridges, cliffs, monuments and any other structure built on undermined land/rock. 2) ECOTOXICOLOGICAL IMPACTS (toxicity in the environment): There are other hazards likely to stem from the infiltration of sea water into areas that had not been accessible to sea waters for millennia, or even millions of years. A key one is the dispersion and bio-concentration of pollutants in the ecosystem. Humanity has been using the land as a waste repository for dead bodies, urban waste, toxic chemicals, radioactive waste, ammunitions etc. When sea water starts to inundate this class of underground voids it will aggressively begin to dissolve the most water-soluble of them and gradually leach them out into surrounding soils and waters. This is how Persistent organic pollutants and heavy metals, in particular, enter into food chains and "food webs"/"food pyramids". Where these plumes of toxic liquor flow into bodies of water, four main processes will take over: A) TRANSPORTATION: currents will transport the toxic effluent out towards the sea B) ADSORPTION/ABSOPRTION: depending on the nature of the sands, silts and rock strata the toxic liquids encounter C) ASSIMILATION: aquatic species will breather and ingest toxic liquor D) BIOMAGNIFICATION: as invertebrates and vertebrates assimilate toxic pollutants in suspension/solution, predators will consume them and accumulate in their tissues. As higher predators consume them, in turn, the process continues "up" the food chain so that, say 1000 plankton >> 100 crustaceans >> 10 fish >> 1 bird/mammal. So, if each plankton carries a toxic burden of 0.1mg this is 1st trophic layer 0.1mcg x 1000 plankton = 100mcg 2nd trophic layer 100mcg x 100 crustaceans = 10,000mcg = 100mg 3rd trophic layer 100mg x 10 fish = 1000mg = 1g So the toxic burden a bird feeding on a dead or dying fish in the above example would assimilate 1g of toxic pollutant for every 10 fish it consumes. The process continues up the food chain, so that a predator consuming 10 birds would assimilate 10 gr. of toxic pollutant. Note that the LD 50 [1] for some substances is just a few as low as a few micrograms. Dioxins, for example, have an LD 50 of just20 mcg/kg of bodyweight. Footnotes. 1. The median lethal dose , LD 50 (abbreviation for "lethal dose, 50%"), LC 50 (lethal concentration, 50%) or LCt 50 (lethal concentration and time) of a toxin, radiation, or pathogen is the dose required to kill half the members of a tested population after a specified test duration. LD 50 figures are frequently used as a general indicator of a substance's acute toxicity.

What might happen to humans if global warming continues?

Humans will have to adapt to changes in their environments. This may mean moving away from low lying coastal plains. It may mean importing wheat or rice or other foods because their climate is now too dry, or too wet, or too hot. It may mean moving to other lands in search of water, if some of the great rivers, now fed by glaciers, lose their source of water. Some lands may be able to grow more foodstuffs because of a changing climate. There will be many changes, in fact, massive upheaval, and the economies of many countries will be severely threatened.

How high will water level rise if global warming continues?

Greenland has sufficient ice to raise ocean levels more than 20 feet. I was surprised when I first heard this, and calculated the result myself. There is some thermal expansion of water as its temperature is raised, so melting the Arctic ice cap would raise ocean levels a little bit, but not a lot. The reason it would not be a big rise is because Arctic ice is already afloat. Arctic ice occupies no more volume than the water it already displaces. Antarctic ice, however, is NOT afloat, and there is sufficient water locked on that continent to raise ocean levels more than 200 feet. Fortunately, even at accelerated melt rates, we expect it will be several thousand years before that ice contributes more to rising sea levels than Greenland's ice.

Will global warming really happen?

Yes. Global warming is not just something scientists predict to happen in the future - it is already happening now. The last ten years were the warmest since instrumental records began in 1850. The more severe consequences of global warming may still be off in the future, but global warming has started.

Where does global warming happens?

Many things cause global warming. One thing that causes global warming is electrical pollution. Electricity causes pollution in many ways, some worse than others. In most cases, fossil fuels are burned to create electricity. Fossil fuels are made of dead plants and animals. Some examples of fossil fuels are oil and petroleum. Many pollutants (chemicals that pollute the air, water, and land) are sent into the air when fossil fuels are burned. Some of these chemicals are called greenhouse gasses. We use these sources of energy much more than the sources that give off less pollution. Petroleum, one of the sources of energy, is used a lot. It is used for transportation, making electricity, and making many other things. Although this source of energy gives off a lot of pollution, it is used for 38% of the United States' energy.

Can you be sure global warming is happening?

The unprecedented reduction of the arctic ice cap, permafrost and mountain glaciers are sure signs that global warming is occurring. Historic records show glaciers around the planet are reducing. Further, ocean levels have been documented as rising several inches, which does not sound like much but has already made several low-lying islands uninhabitable. Anyone who remembers the phantom pursuit of the "Northwest Passage" recalls that trying to find a sea route to Asia from Europe through a waterway across or around North America failed because no river spans between the Atlantic and Pacific oceans, and because when you go too far north, you run into the 'permanent' Arctic Ice Cap. The Arctic Ice Cap has existed for millions of years, but at the current rate of melting, will disappear entirely within a decade or two; it has already receded to the point that much of the Eurasian and North American north coastlines are ice-free much of the year where they had never been so before. Glaciers in mountains serve as reservoirs that let rivers run, even when there are no rains to actively feed them. On every continent except Antarctica, the glaciers are disappearing and that is both a sure sign of global warming and the mark of a coming calamity; there is reduced drinking water available, and as more glaciers melt away, will continue to be reduced drinking water available. The evidence is already clear that global warming is already occurring.

What proof is there that global warming is not happening?

There is no proof that global warming is not happening. After therecent record global average temperature of 1998, there was a lull,with subsequent years recording lower average temperatures, butthis is to be expected as part of normal climate fluctuations. Someoptimists nevertheless saw that as proof that global warming hadstopped, or even reversed. However, the year 2005 matched theaverage global temperature of 1998, then 2010 actually exceededthat temperature by a fraction of a degree. There is therefore noproof that global warming is not happening. A: Many people think the the Earth is going through "global warming".Is it fact or just a therory? Well, from what I have learned (frommy theacher and his long speaches) that "global warming" is fake.The Earth goes through a cylcle of changing weather. One day it maybe cold. Then the next it's hot. The Earth's weather is just likethat. Antarctica (the place of the so called "global warming") hasbeen frozen, and frozen very well. In fact it's been frozenforever. The temperature there on about August 20th was at about-10 degrees. That's pretty cold! If you have internet on your Wiigo to the weather channel and you can look at the globe to seeplaces weather daily. That's just a little something you can do. Ina nut shell, the Earth is not going through "global warming". Also, Antarctica has actually cooled. Dr. Peter Norman and hiscolleagues have found out that since 1986 Antarctica has beencooling an average of 1.2 degrees Fahrenheit per decade. Also, theearth is coller now than it was 1000 years ago. In which was knownas the Medieval Warming Period the temperature was warmer than itwas in the 1990s and the Medieval Warming Period was before theindustrial revolution and the emission of greenhouse gases. If we are to assume, as we have been instructed to do so, thatglobal warming refers to the main induced portion of the currentwarming cycle, we have some interesting data. The planet appears to have cooled this past year. Sea level has not increased as predicted and has actually beenslower presently than past decades. Sea level has even gone down 6 mm this past year. The bulk of the planets warming happened before 1939. we are only afew tenths of a degree (plus or minus a few tenths) away from thetemperatures of 1938 The Antarctic has not seen overall ice loss. CO2 has always followed temperature. Despite massive increases in the use of fossil fuels, we saw globalcooing from 1939 until 1979. The years 1939, 1998 and 2010 arealmost identical, with cooling between those years. IPCC models have not been able to reproduce current warming andcooing trends. The IPCC admits in their policymakers paper that the interaction ofwater vapor (the predominant greenhouse gas) is still not fullyunderstood. UAH Satellite documentation shows cooling of lower troposphere to0.09 degrees below the 1981 average for that layer of atmosphere. Answer What do you mean? Global warming exists. It's reality. Answer Even prior to the current cooling, between 1975 and 1998, whenglobal average annual temperatures were supposedly going up, thereis now considerable reason to doubt that they were really going up. See the link below to surfacestations.org. It appearsthat 87% of the temperature-recording stations in the US alone arelocated within 30 meters of an artificial heat source, which biasestemperatures upward by at least 1oC. By my own calculations, theUS's portion of the "official temperature record" has an averagebias of slightly more than 3oC. Since the US makes up 9% of theland area on the planet, even if the rest of the world'stemperature recording stations are completely unbiased (notlikely), the bias in the US alone accounts for 0.27oC, or nearlyhalf of the 0.6oC increase in global average annual temperatureobserved over the last 40 years. But it is more likely that, atleast in Canada, Europe, and China, the observations are subject tosome degree of positive bias. It would not surprise me at all if,once all of these biases were quantified, the actual temperature has not gone up at all over the last 40 years, and may have gone down . In any event, the analysis by surfacestations.org proves that actual temperatures have not gone up nearly as rapidly asthe 0.15oC per decade claimed. This is a crucial point becausealarmists have finally been forced to admit not only that globalwarming occurred in the past, in a regular, 1,000-year cycle (thelast three episodes are now called the Minoan, Roman, and MedievalWarm Periods), but that the peak temperatures during all three ofthese past events exceeded the highest temperatures achievedduring the "current" warm period. So now they have fallen back onthe claim that the "current" warming is unique because of how rapidly temperatures have been rising, continually pointingto that 0.15oC per decade statistic. But that statistic is nowproven to be positively biased, and the actual rate ofwarming, even if the only the US's temperatures are biased, is onlyabout 0.08oC per decade. This puts it below the rate of warming ofall three of the previous warm periods. So once again we are leftwith the unavoidable conclusion that the current warming is notunusual at all. Answer The El Nino of 1997-1998 was thestrongest on record, and is one of the major (but not only) reasonsfor the record heat. The temperature has not been going down since1998 - it has remained high, and in fact the hottest decade inrecorded history followed. But no, none of those years were ashot as 1998. Obviously, since then the SOI has oscillated as italways does and there have been multiple La Ninas and El Ninossince; I'm not sure what one would derive from that in terms ofdenialist arguments. The record of temperatures is far more robust than volunteer UnitedStates stations. The warming has been verified at all levels of thetroposphere, in ocean temperatures and in innumerable proxyrecords. This issue has been addressed. Temperatures declined prior to the 1970's slightly due to the largeamount of aerosols that were being pumped into the atmosphere bycountries such as the United States; aerosols have a net coolingaffect. We are now seeing the same thing in India and China, andthis is even evidenced in temperature trends that have leveled offor slightly declined in that region. Furthermore, temperatures now are warmer than they were during theMedieval Warm Period or the prior two (and there is really far toomuch uncertainty for temperatures going back this far). Thisstatement otherwise was popularized by Ray Evans, who cites afigure taken from a paper (Grootes et al. 1993) which simply is notthere, it does not exist. The figure, that is, not the paper. And since the current warming doesn't fall in line with anynatural cycle, real or fictitious, where does that leave us? No, itdoesn't leave us with the conclusion that the current warming isanthropogenic. That would be lazy and dishonest science. We havecome to that conclusion for many, many reasons. We know what theradiative properties of CO2 are from studies done in the 19thcentury; this is solid. We know how much CO2 and other greenhousegases we have liberated into the atmosphere since the industrialrevolution. We have observed the rise in temperature, accounted forerror and uncertainty, and have been doing this since before AlGore ever noticed it was getting hotter. Climate models can do aremarkably good job of recreating the observed temperature, butthey can only do it with an input of anthropogenic greenhousegases. Without them, they show a slight cooling, which deviatesmarkedly from the trend of the last several decades. Answer The current decade MAY be the hottest on record. All thatproves is that we hit the maximum during the current decade. Evenafter adjusting for El Ninos and other fluctuations, the 5-yearaverage of global average temperatures has definitely turneddownward. Is this just a bigger fluctuation? Or is it a sign ofthings to come? Nobody knows yet. Temperature is what global warming is all about. Proxy data arejust estimates of actual temperatures, and there are many sourcesof error in these estimates. For that matter, as illustrated byAnthony Watts, recorded temperatures are only estimates ofactual temperatures, and they are particularly bad estimates insome cases, with confirmed positive bias of over 5 degrees C insome cases. What global warming theory says is that, if globalwarming is caused by greenhouse gasses, there will be more warmingin the upper troposphere than at the surface. The observationaldata, by satellites, shows exactly the opposite. So, even if theupper troposphere really is warming, it's warming more slowly thanthe surface. This clearly points to a cause other than greenhousegasses. Answer It does exist. Evidence supporting its existence is extensive. Forone, based on geological data and evidence, the Earth is supposedto be in a period of cooling, but instead our temperatures haverisen 0.74ºC (from 1906-2006). Our temperatures have onlycontinued to rise, and are projected to rise anywhere between 1.8to 4.6ºC in the next 100 years. This is an exponential increase,as from the time of the last ice age to now, the Earth's meansurface temperature only increased 3.5ºC. Our rising sea levels indicate global warming, not merely due tomelting ice caps, but also because when water warms, the moleculesexpand. A more accurate term than global warming is global climate change,as not all areas will warm, and climate change will not be uniform. People who say global climate change/warming does not exist do nothave concrete scientific facts to dismantle the basic facts: thatgreenhouse gases are increasing, and are directly correlated withthe raise in the temperature in many places of the world. Answer We were warming over the last couple of centuries, and the warmingnow appears to have stopped. I do not dispute that atmospheric carbon dioxide is increasing. Nordo I dispute that temperatures were increasing from around 1975 toaround 2000, and that there is, therefore, some degree ofcorrelation between atmospheric CO2 and global average temperature.However, correlation does not prove causation . Take astatistics class and you will learn this. Statistics classes arechock full of examples of two things that are highly correlated butcannot possibly have a causal relationship. For example, somestatistician found a high correlation between the stork populationin a French city and the human birth rate in the same city. Heconcluded that storks delivered babies. Of course, he was notserious, but was trying to prove the absurdity of equatingcorrelation and causation.

Why is global warming still happening?

Too many greenhouse gases. For example: - Methane Gas: Released via cattle and rice farming.. - Carbon Dioxide: As a result of human activity (burning fossil fuels.)

Is Venice concerned about rising sea levels from global warming is?

Yes, Venice is very much so in danger of rising sea levels. The city has in fact for the past 2 decades, and locals haven't lived on the first floor of their homes for 10 years. Currently the city is looking for ways to block the water from getting in. Other issues with the city include the overpopulation of green algae, attributing to the green color and stench of the otherwise beautiful canals.

Why and how is global warming happening?

When we talk about global warming, we usually refer to the increase in average global temperatures since the beginning of the Industrial Age. Climate scientists say that this results from increased levels of greenhouse gases, particularly carbon dioxide, and that human activities are a substantial cause of these increases. We are adding to the concentration of atmospheric carbon dioxide by burning fossil fuels, manufacturing cement and by deforestation. Greenhouse gases cause global warming by allowing the sun's energy to pass through to the earth's surface as vivible light, but blocking the re-radiation of that energy from the earth's surface as infrared heat.

Will sea levels rise with global warming?

Yes. Scientists say they rose by a relatively modest 20 centimeters during the twentieth century, but are predicted to rise between 90 and 150 centimeters during the present century, depending on our progress in minimizing greenhouse gas emissions.

Why does it snow if global warming is happening?

Fortunately global warming has not reached the point that we no longer get snow, although some marginal snow fields usually get less snow that in former years. Also, at the 2010 Winter Olympics, snow had to be trucked in from kilometres away in order to provide a proper winter ambience, as the local snowfall had been so unexpectedly low. In other areas there may be a higher than average snowfall in some years. This is part of natural variation in climate.

How does global warming lead to the rising of sea level?

As glacial ice melts and recedes, all that water ends up draining into the oceans. The Greenland ice pack is large enough to raise sea levels about 7 meters (close to 23 feet). Although the arctic ice is not resting on anything and thus would not contribute significantly to sea level rise, there would be some small elevation due to thermal expansion, and there is a lot of other arctic ice in northern Europe, Asia, and North America. Although no one expects the Antarctic ice cap to melt for centuries to come, that ice would raise ocean levels several hundred feet, dramatically altering earth's coastal landscape.

What are the effects of global warming on sea levels?

Global warming causes sea levels to rise, for two main reasons. Water expands as it becomes warmer, so global warming heats the ocean and cause the water to expand. The loss of glacial ice (but not sea ice) is another contributor to rising sea levels. These events have resulted in a rise of 20 centimetres over the course of the twentieth century. As recently as 2007, the Intergovernmental Panel on climate change predicted a further rise of 59 centimetres for the twenty first century, but recent data has now resulted in the United Nations Arctic Monitoring and Assessment Program to revise this prediction upwards, to 0.9-1.5 metres. A: The result of higher global temperatures is not only that they could reduce the amount of sea ice in the Arctic and Antarctic, but also thaw glaciers, and ice caps in Greenland and Antarctica. Water melting from ice caps or glaciers that are above sea level will flow into the oceans, raising their level. A: Glaciers and ice shelves around the world are melting. The loss of large areas of ice on the surface could accelerate global warming because less of the sun's energy would be reflected away from Earth to begin with (the albedo effect). An immediate result of melting glaciers would be a rise in sea levels . Initially, the rise in sea level would only be an inch or two. Even a modest rise in sea levels could cause flooding problems for low-lying coastal areas. However, if the West Antarctic Ice Sheet were to melt and collapse into the sea, it would push Sea Levels up 10 meters (more than 32 feet), and many coastal areas would completely disappear beneath the ocean. If global warming is not slowed or stopped then sea levels will rise, because of glaciers and ice caps melting, mainly in Greenland, Alaska and the Antarctic. The Antarctic alone has ice 2133 meters (7000 feet) thick - more than two kilometers thick. If all this melted it would raise sea levels all round the world by 61 meters (200 feet).

How can global warming cause sea levels to rise?

Glacial ice melt inevitably ends up in the oceans. There is enoughice on Greenland to raise ocean levels approximately 7 meters(almost 20 feet). Antarctic ice is not expected to melt forcenturies, but there is enough fresh water locked up there to raiseocean levels some 60 meters (200 feet). Thermal expansion ofseawater is another contributor to this.

Why does sea level rise due to global warming?

if cabondioxide increases then immediately tempreture increases it effects global warming when tempreture rises the earth surface's tempreture will be increased that due to the rise of the sea waves in the sea.

What will happen to the UK's agriculture if global warming continues?

We don't know. Global warming may cause the Gulf Stream, whichkeeps the UK warm, to slow or stop. This would make Britain colderthan it is now. However, if global warming continues Britain willthen become warmer and warmer. There may be more rain or less rain.All this will cause problems for farmers and agriculture.

Why is global warming continuing?

Global Warming is continuing because all around the world people are still burning fossil fuel (coal, oil and natural gas) and all the carbon dioxide emitted is adding to the greenhouse gases. This will continue till we start using renewable energy for transport and electricity. Then global warming may slow down.

Is sea level rising as a result of global warming?

Yes it is. For most of the last century sea levels rose at 2 mm ayear, and since the later years of the 20th Century they have beenrising at 3 mm a year. Warmer oceans mean that the warm waterexpands. This is the main cause of the rise. A secondary cause isthe melting of land ice.

Why is sea level rising as a result of global warming?

Sea levels are rising mainly because warm water expands, and theoceans have been warming steadily over the past 40 years. Meltingland ice is also adding to rising sea levels. A common error in climate debate is to focus on short term datainstead of looking at long time trends. All sea level graphs (aswell as temperature graphs) zig zag up and down. Some years sealevels go down, and the oceans cool, from cyclic events like LaNiña (cooling) and El Niño (warming). Other years oceans warm andsea levels rise. Some people try to argue that a downward zag meansthe sea level rise has stopped, but the long term trend shows thatlast century sea levels were rising at 2 mm a year, and that sincethe later years of the 20th Century they have been rising at 3 mm ayear.

How does the rise in sea level support the theory of global warming?

If sea levels are rising this can be caused by two things: . Extra water added to the oceans. This can only come from land ice melting. . Ocean water expanding as it gets warmer. We know that sea levels are rising because our satellites measure this. This therefore supports the theory of global warming.
