Bad scenario in 2060

In the worst case scenario, world temperatures can rise to 4 degrees Celsius by 2060, countries need to spend an average of $ 270 billion a year just to cope with rising sea levels.

That is the prediction of international expert groups at the UK-based Royal Society Institute, after concluding that global greenhouse gas emission reductions today do not prove as effective. expectations. According to the Telegraph, scientists predict that global temperatures will rise by more than 4 degrees C in 50 years.

The rapid rise in temperature, which took place in a lifetime, was twice as high as the ceiling of 2 degrees Celsius set by 140 countries and territories during the Climate Change Conference last year. . As a result of this latest scenario, the supply of water and food in many parts of the world will be stalled.

Studies with extremely bleak predictions have been published coinciding with the UN climate change conference held in Cancun, Mexico, starting November 29. There are only a few scientists who have ever studied the terrible effects of world temperatures rising by 4 degrees Celsius, but according to Oxford University expert Mark New, the impact will be more severe for coastal cities. cultivation, fresh water systems, ecosystems .

One of the studies has given the so-called ' pragmatic estimate ', whereby sea level in the world can rise from 0.5 to 2m in 2100, if the temperature increases by 4 degrees C.

To cope with an additional 2m sea level rise, the world needs an investment of up to 270 billion USD / year by 2100. At that time, drought and desertification will take place on a large scale, need to shift cultivation elsewhere, ecosystems will be terribly impacted, according to Rachel Warren of the University of East Anglia.

In addition, the lack of safeguards means forced relocation of 187 million people. People living in small islands, in Asia, Africa or river deltas belong to the group that faces the highest risk.

Studies conclude that governments need to be more aggressive in cutting greenhouse gas emissions and at the same time studying support measures to cool the earth.
