Journalist Mark Lynas scientific literature published by HarperCollins , and won the prestigious Royal Society Science Books Prize.1 In the book, Mark Lynas , explained what was going to happen any temperature rise 1 º C to 6 º C. UN Climate Change Agency , the Intergovernmental Panel on Climate Change ( IPCC ) , has warned that if greenhouse gas emissions continue to increase as the level allowed at present, then the temperature of the Earth 's surface at the end of the 21st century will rise from 1.1 º C to 6.4 º C.2

What will happen to the temperature of the Earth's surface every 1 º C rise ? Here are the results of scientific investigations Mark Lynas.3
Air Temperature Rise 1 º C
Sea ice is starting to lose on it will absorb more heat and accelerates global warming ; fresh water vanish from the Earth 's surface one-third ; lowland areas on the coast will be hit by floods .
Air Temperature Rise 2 º C
Europe receives exposure to high heat ; forests damaged by fire ; plants are stressed , rather than absorb carbon , start releasing carbon into the atmosphere that once absorbed ; -third of the world's species are threatened with extinction .
Air Temperature Rise 3 º C
Carbon released by plants and soil on Earth accelerates global warming ; demise of the Amazon rain forest ; powerful typhoon struck the seaside towns ; famine in Africa .
Air Temperature Rise 4 º C
The melting of the ice sheet resulted in uncontrolled global warming unstoppable ; most areas of England uninhabitable due to flooding sunset ; abandoned populated Mediterranean region .
Air Temperature Rise 5 º C
Methane gas that comes out of the ocean floor accelerates global warming ; ice at the North Pole and South Pole exhausted ; humans to move where to look for food and tried , though in vain , to live like animals in the wild .
Air Temperature Rise 6 º C
Life on Earth ends due to a major storm , flood , fire balls of hydrogen sulfide and methane swirling quickly flashed around the world with the power of the atomic bomb ; fungus can only survive .
How does the impact of global warming according to the UN climate body ? Average global temperatures according to the IPCC reports has increased by 0.6 ° C from 1850 to 2000 . IPCC presents the impact of global warming based on the rate of temperature increase and will be more severe with increasing temperature .
The increase in air temperature 1-2 º C will cause the productivity of cereal dipped in the southern hemisphere . Air temperature rise above 4 º C will reduce food production around the world .
Health Worsens
Temperature increase above 1 º C would threaten the health condition as a result of malnutrition , diarrheal diseases , because infectious diseases , drought , high heat , and other causes .
Thinning Water Supply
The temperature rise of up to 1 º C will reduce water supplies and increase droughts in equatorial regions . Temperature rise above 1 º C will cause floods , droughts , erosion , and water quality has declined. Rising seas will expand salting ground water thereby reducing fresh water supplies for areas on the coast . Hundreds of millions of people will face water shortages .
Population Movement and Conflict
Stress caused by increased drought , water shortages , and floods in the basin and on the coast will force residents find a new place , be it within their own country and enter another country . This can lead to conflict and tension between old and new residents .
Species Extinction Mainland
The temperature rise of up to 1 º C will damage many ecosystems , which are already starting to look like now . Temperature rise above 1 ° C will lead to 20-30 % of species threatened with extinction . Temperature rise above 4 º C will cause the extinction of nearly all the species around the world .
Damage to Marine Ecosystems
The temperature rise of up to 1 º C will increase coral bleaching . The temperature rise of 1-2 ° C would cause large numbers of corals were bleached . Temperature rise above 2 ° C will cause the demise of coral reefs on a large scale .
Freshwater Ecosystem Damage
Some lakes have shown shrinkage with temperature increase the number of fish that began walking close to 1 º C as it is today . A number of species commonly found in the warmer regions move toward the polar regions . The rise in temperature of 2 º C to 3 º C lead to large increases hydrological cycle , more droughts , and floods . Meanwhile , the extinction of many freshwater species , changes in the structure of a massive lake , increasing acidification of lakes can occur at temperatures rise above 4 º C.
Ocean Acidification
Ocean acidification is already occurring , and will further increase with the increase in atmospheric CO2 concentration .
Release of Methane and Carbon Dioxide
Temperature heats will cause the release of methane and carbon dioxide from the polar ice caps , peat , swamp land , and sea .
The melting of the Greenland Ice Sheet
Now this is a layer of ice in the Arctic has begun to melt . Temperature rise above 1 º C to 4 º C will melt most of the ice and sea water will rise as high as 2-7 meters over centuries to millennia . Temperature rise above 4 º C will cause the ice to melt almost completely .
The loss of ice shelves in some places at a temperature rise of up to 1 º C is already visible . Temperature rise above 2 ° C will cause some areas of the West Antarctic ice melts and sea level will rise by 1.5 to 5 meters over centuries to millennia .
Category 4-5 hurricanes will increase the temperature rise to 2 º C and the impact will be exacerbated by rising seas . Temperature rise above 2 º C increase the intensity of hurricanes and many lives are threatened .
Flash floods in many places will become more frequent due to increased rainfall intensity . Flooding will also become increasingly common in low-lying areas .
Heat wave
Heat stress and heat waves has increased as the temperature increases to 2 º C. On top temperature of 2 º C , the frequency of heat waves will increase rapidly and cause death , crop failure , death of new shoots of trees , forest fires , and damage to ecosystems .
Drought
Temperature increase to 2 º C causes more drought are common . It is estimated that the frequency and intensity of drought in the equatorial region is increasing. Meanwhile , the air temperature rises above 2 º C , will cause extreme drought increased from 1 % to 30 % .
Fire
The increased frequency and intensity of fires in many places , especially in places where drought occurs , the temperature rise to 2 º C. Temperature rise above 2 º C progressively increased the frequency and intensity of fires great , especially in forests and peat lands in the northern hemisphere after the melting of the ice sheet .
