Emissions increased by 27% compared to 650,000 years ago

Sea level and greenhouse gas emissions are increasing faster

Ocean water levels and greenhouse gas emissions are rising faster than this phenomenon for thousands of years, according to two new reports released yesterday, further sparking controversy about global warming. .

A study by American scientists found that the water level in the Earth's oceans increased twice as fast in the last 150 years, a sign of the impact of human activities on global temperatures. gender.

In the journal Science, researchers at Rutgers University in New Jersey said sea level has risen by about 1 mm each year at about 200 years ago and beyond, about 5,000 years ago. Since then, sea level has risen about 2 mm per year.

According to them, the oceans will rise almost half a meter by the end of the century, forcing the shores to retreat hundreds of meters deep.

In another report published in Science, European researchers have discovered that the amount of carbon dioxide in the past has not changed until 200 years ago. However, at present, " carbon dioxide increases 200 times faster than the previous increase, " said Thomas Stocker, climate researcher at the University of Bern.

That also means that carbon dioxide is currently 27% higher than this at 650,000 years ago and that methane, which is also a greenhouse gas, is 130% taller, according to Thomas Stocker.
