The temperature of the Earth is at an increased risk of 5 degrees Celsius

The world will have to cope with even more catastrophic warming than expected and if it does not change the trend of increasing greenhouse gas emissions , the Earth's temperature is likely to increase by 5 degrees Celsius. a century to the average of the industrial era.

It is a warning of Mr. Nicholas Stern, a senior economist at the World Bank (WB).

According to the former British economist, greenhouse gas emissions that cause climate change along with its effects are much faster than he predicted seven years ago.

According to his analysis, three million years ago when the Earth's temperature increased by 3 degrees Celsius, the sea level was higher by about 20 meters today. As long as the sea level increases by 2m, about 200 million people worldwide will have to leave their homes.

Other consequences of climate change are also occurring faster, such as increased desert areas, snow melting in the Himalayas.

Mr. Stern warned that even if countries were to comply with the commitments made at the UN Conference on Climate Change in Cancun, Mexico in 2010, the Earth's temperature would still increase by 4 degrees Celsius. .

Mr. Stern is the author of a 700-page study that has a big impact in 2006 on global climate.

His research is considered a turning point in raising the international community's attention to climate change.
