Earth will become a giant greenhouse

Scientists warn fast-moving countries to move to a green economy because pollution from fossil fuels will put the Earth in danger in the long run.

If the polar ice sheets continue to disintegrate, forests are cut down and greenhouse gases increase after each year, the Earth will transition to a new phase.

"The climate will be 4-5 Celsius hotter than pre-industrial and sea level rise 10-60 m from the present," scientists warned on August 6. That 'will come in just a few dozen years ', scientists said.

The report was published in the hot sunshine raging in Europe and many parts of the world. Hot sunshine leads to forest fires in Greece, Spain, Portugal, America . melting glaciers in the Kebnekaise mountains, Sweden.

Become a greenhouse

The greenhouse state is the phenomenon of global warming due to keeping heat from the Sun instead of dispersing heat back to the outer space, similar to a greenhouse.

'Earth in a greenhouse state is uncontrollable and dangerous to many people' , according to research by the University of Copenhagen, Australian National University and the Potsdam Climate Impact Research Institute in Germany.

Water in high-rise river systems and storms in coastal areas and coral reefs face the risk of disappearing. All of this may happen at the end of the 21st century or even sooner.

According to the study, the average global temperature will exceed the temperature of the interglacial period in the past 1.2 million years. Ice space is an intervening period between the Ice Age when the Earth's temperature is warmer at melting poles.

Melting ice leads to sudden sea level rise, flooding coastal areas and affecting hundreds of millions of people living in these areas.

"Many places on Earth will not be able to live if" The Earth Greenhouse "becomes a reality" , co-author Johan Rockstrom, executive director of the Stockholm Recovery Center, said.

Where does the extreme threshold of the Earth come?

Researchers say the threshold of change will come when the Earth's temperature is 2 degrees Celsius higher than the pre-industrial stage. Currently, the global temperature has increased by 1 degree Celsius and the planet will continue to heat up at a rate of 0.17 degree / decade.

'Warming of 2 degrees Celsius may trigger important factors, causing temperatures to rise even further and continue to cause many other changes. Like the domino effect, this will cause the Earth to get hotter , 'the scientists wrote in the report.

Each successive turn of events such as 'might bring the Earth to a new state' , co-author Hans Joachim Schellnhuber, director of Potsdam Climate Impact Research Institute, forecast.

Experts fear that phenomena such as forest fires will be widespread due to the hot and dry Earth. This may increase the amount of CO ₂ accumulating, leading to global warming.

The way to find the Earth's ultimate point

The study is called Perspective, which is based on previous studies on the Earth's threshold.

Scientists studied environmental conditions in the past, such as in the Pliocene period 5 million years ago, the CO ₂ density was 400 ppm, similar today. During the Cretaceous reign of dinosaurs 100 million years ago, CO ₂ levels were even higher, reaching 1,000 ppm, mainly due to volcanic activity.

The authors study 'comparing previously published ideas and theories to show the mechanism of extreme points' , Martin Siegert, co-director of the Grantham Institute of the Royal Institute of London, is not involved in the study. save, said.

Siegert also judged that the 2 degrees Celsius of the Earth's "no return" is the new point of this study.

Stopping greenhouse gas emissions, the Earth still warms up

According to the researchers, people need immediate lifestyle changes to become better owners of the Earth.

Fossil fuels need to be replaced by energy sources that do not emit greenhouse gases or emit only a small amount. People need to think of measures to absorb carbon emissions, namely planting more trees and preventing deforestation.

Cultivation methods, effective land management, land and coastal conservation, and utilizing carbon capture technologies are also things people can do.

However, the current warming trend will continue to cause changes such as polar ice melting and deforestation. The amount of snow covering the Northern Hemisphere will also disappear. In other words, even if we stop greenhouse gas emissions, global warming continues.

In that context, researchers warn the Earth is unlikely to maintain stability.

'What we do not know is whether the climate system can safely "land" near the 2 degree Celsius increase compared to the pre-industrial era as outlined by the Paris Agreement , "said Schellnhuber.
