What does global warming change?
global warming is bad

If global warming were real and not just a big hoax put on by envirnmental extremestists, it could actually be looked at as a good thing. But, once again, it is NOT REAL. We have only kept records of global climate for about 150 years. The earth has been around for MILLIONS of years BEFORE people.

Global warming is the increase in the average temperature of the Earth's near-surface air and the oceans since the mid-twentieth century and its projected continuation. Global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 100 years ending in 2005. The Intergovernmental Panel on Climate Change (IPCC) concludes that anthropogenic greenhouse gases are responsible for most of the observed temperature increase since the middle of the twentieth century, and natural phenomena such as solar variation and volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect from 1950 onward. These basic conclusions have been endorsed by 30 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries.

Climate model projections summarized in the latest IPCC report indicate that global surface temperature will likely rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the twenty-first century. The uncertainty in this estimate arises from the use of models with differing climate sensitivity, and the use of differing estimates of future greenhouse gas emissions. Some other uncertainties include how warming and related changes will vary from region to region around the globe. Although most studies focus on the period up to 2100, warming is expected to continue beyond 2100, even if emissions have stopped, because of the large heat capacity of the oceans and the lifespan of CO2 in the atmosphere.

Increasing global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, likely including an expanse of the subtropical desert regions. Other likely effects include Arctic shrinkage and resulting Arctic methane release, shrinkage of the Amazon rainforest (already very damaged by deforestation from logging and farming), increases in the intensity of extreme weather events, changes in agricultural yields, modifications of trade routes, glacier retreat, species extinctions and changes in the ranges of disease vectors.

Political and public debate continues regarding the appropriate response to global warming. The available options are mitigation to reduce further emissions; adaptation to reduce the damage caused by warming; and, more speculatively, geoengineering to reverse global warming. Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions.
Global temperatures have increased by 0.75 °C (1.35 °F) relative to the period 1860–1900, according to the instrumental temperature record. This measured temperature increase is not significantly affected by the urban heat island effect. Since 1979, land temperatures have increased about twice as fast as ocean temperatures (0.25 °C per decade against 0.13 °C per decade). Temperatures in the lower troposphere have increased between 0.12 and 0.22 °C (0.22 and 0.4 °F) per decade since 1979, according to satellite temperature measurements. Temperature is believed to have been relatively stable over the one or two thousand years before 1850, with possibly regional fluctuations such as the Medieval Warm Period or the Little Ice Age

i have forgotten if it was mentioned, but global warming can melt the ice caps and flood basically the whole world. global warming can more or less become the apocolypse as everything would be underwater. just imagine atlantis.
now imagine the whole entire world like that, with the exception of highly elevated regions.

for further information go to www.wikipedia.org and type in global warming in the search bar.
hope this helped
good day ;)


global warming actually isnt as bad as everyone is making it out to be-- politicians make it seem like global warming is our fault; in reality, the earth goes through certain stages in its life... every 600-800 years, the earth heats up a certain amount-- there is scientific evidence of this. (other scientists claim that the intevarls are 100,000 years) however, obviously, our co2 output is also adding to this.... search it online


global warming is the increase in temperature of earth . this causes the melting of ice of south and north poles. which will cause the rise in water level of the sea. this rise in water level will reduce the land available to us.
because of rise in sea level the small islands and the cities close to the seashore are going to be droned. this will cause a massive problem to our ecosystem. many of the spices which lives of ice of south or north pole will die. due to increase in sea level and increase in temperature our climatic conditions would be unstable and will lead to extinction of species which do not adapt them rapidly to these conditions and thing would be out of over control.

Global Warming is just a way that the governments of the world can tax the hell out of us, The Oceans of the world create more carbon than we ever could, The Tree's absolutely love Carbon Dioxide, The more of it in our atmosphere the quicker and more healthy they grow :)

The sun is the cause of our recent heat pattern, Even the polar ice on Mars are melting, Look it up, The past year and a half the earth has actually cooled!!

It thins the ozone layer which protects us from the suns radiation.
it causes the temperatures to go out of wack, not just up, but also down
it's changing habiats, which are effecting animals
its melting the polar ices caps which is cause polar bears to drown
its polluting our oceans, rivers, lakes etc and poisining the fish we eat
the polar ice caps are melting, causing flood, and more rain fall.
acid rain
etc


Everything, for one it doesnt snow in Denver anymore, in the 80s in March? I live in Georgia now, and its way too hot for March. Its too late now to do anything, we might as well say the hell with it.

it causes the temperature to rise and melts the polar ice caps
