The current situation of human living environment on earth
The earth’s climate and environmental disaster will reach the critical point of detonation at 2 degrees Celsius.
Lynas, Mark Lynas Six Degrees: Our Future on a Hotter Planet: "There should be panic in the streets right now, with people shouting from the rooftops, Congress issuing emergency declarations, and television stations providing round-the-clock coverage. .
The "positive feedbacks" effect will turn the currently understood global warming process into useless paper. This process will not be a gradual, linear increase in temperature, nor will nature gradually succumb to the torture imposed on it by humans. Instead, nature will fight back.
In September 2008, the British newspaper "The Independent" reported that scientists discovered that millions of tons of methane, a gas 20 times more powerful than carbon dioxide, was being released into the atmosphere from the bottom of the Arctic ice sheet.
Figures show that the atmosphere will no longer absorb and contain greenhouse gases, but will suddenly spit out these toxic gases - the accumulated carbon and methane will be dumped out uncontrollably in a major explosion, and Flood or burn entire cities. Icebergs will melt massively, and the Amazon rainforest, Earth's most important lung, may cease to function entirely. A vicious cycle will begin that threatens not only our current way of life, but the very existence of ourselves and other species.

The ice will reflect sunlight into the air, but because the ice is melting so quickly now, there is not enough ice to reflect the sunlight, and because sea temperatures have warmed, it will melt the ice. And because the ice is melting, the ocean temperature is higher, creating a vicious cycle.
An analysis report jointly led by the British-Finnish team shows that sea levels have been stable in the past 2000 years. Measurements show that in the 18th and 19th centuries, sea level rose by only 2 centimeters and 6 centimeters. However, in the past century, it suddenly rose to a staggering 19 centimeters, or even more than half a foot. The most likely cause is melting ice sheets. It is predicted that by the end of this century, the global average sea level will rise by 0.8 to 1.5 meters.
If the ice in the Arctic and Antarctic melted completely and the seawater subsequently warmed, then extremely large amounts of toxic gases could be released from the ocean. Dr. Ron G Prinn of the Massachusetts Institute of Technology pointed out that if the permafrost of the northern ice sheet dissolves, it will release 80 times more methane into the atmosphere every year than currently, and every 4 degrees Celsius increase in global temperature will This means sea levels will rise by 5 meters.
According to the current rate of warming, if the government does not try to solve the problem, everything will be over in four to five years. There will be no time to recover. It is really urgent. "

Discuss numerous scientific studies and outline the changes that will occur for every 1°C increase in temperature:
1°C increase: global food shortage
The melting of Arctic ice is accelerating, causing dramatic climate changes; atoll islands are about to sink, coral reefs continue to be severely bleached, wider and more severe droughts are becoming more frequent, African mountains are devoid of ice and snow, and one-third of the world's surface will lack fresh water. More suitable for human habitation.
2℃ rise: more than one million species of organisms will decline
The oceans continue to warm and acidify, destroying the food chain and destroying all remaining coral reefs. The Greenland ice sheet continues to melt. The disappearance of Arctic sea ice has caused the extinction of polar bears. The water crisis has become more serious. How to distribute global food has become more difficult.
3℃ rise: A large number of climate refugees will emerge
The entire carbon cycle process will be reversed. Soil and plants will no longer absorb carbon, but will begin to spit out large amounts of carbon. Most of the Amazon rainforest will be burned into a desert, and a mass extinction of organisms will begin.
4°C increase: scorching high temperatures will dominate everything
Sea levels continue to rise, submerging coastal cities, the Antarctic ice sheet begins to collapse, and the two poles will become ice-free. The permafrost begins to melt and release large amounts of carbon dioxide, causing an imbalance in food supply and demand.
5°C increase: the world is completely out of shape
The remaining ice sheets in the South and North Pole will no longer exist. Rising sea levels have swallowed up coastal cities and are preparing to attack the interior. Under the double attack of droughts and floods, humans have poured into the gradually shrinking habitable areas, and the population has declined significantly. .
6°C rise: mass extinction
Humanity will collectively perish!

One degree 0.1-1.0oC 350ppm (currently reached 380ppm)
Second degree 1.1-2.0 oC 400ppm
Third degree 2.1-3.0 oC 450ppm
Fourth degree 3.1-4.0 oC 550ppm
Fifth degree 4.1-5.0 oC 650ppm
Six degrees 5.1-5.8 oC 800ppm
The global climate and environmental disaster will reach the critical point of detonating at 2 degrees Celsius. This is a global human emergency. This is a morality and responsibility that the leaders of the 244 political entities around the world must deal with urgently today.
Human beings on Earth will eventually establish a worldwide Earth Central Parliament and a worldwide Earth Central Government to coordinate global issues that cannot be dealt with by individual countries.
Leaders of countries or political entities must realize that today's world has reached an era where global mankind must be the people of the world. It is inevitable to establish a world-wide Earth Central Parliament and a world-wide Earth Central Government to jointly safeguard the world. a common environment, jointly implement international government affairs, coordinate global issues and government affairs that cannot be handled by individual countries, formulate and implement common laws for human development in the world, and jointly safeguard the republican development of global mankind on the entire planet. 引爆临界点， SOS！ 敬告244个全球政治实体领袖
