Because of the top polluting countries, every two years will experience extreme heat similar to that seen once in a century.

New Delhi: According to the New Scientific Paper on Communication Earth and Environment, the number of countries experiencing extreme heat will double every other year by 2030 due to pollution from India, China, the US, the European Union and Russia between 1991 and 2030. The report says that the polluting countries are warming the earth rapidly.

Scientists led by ETH Zurich and climate analysts studied the impacts of the world’s top five polluting countries from 1991 to 2030 and from 2016 to 2030. They would account for 52% and 53% of the world’s total pollution.

By 2030, 92 percent of all countries will experience extreme heat every other year, given the current goal of reducing pollution. This is more than double the 46 percent non-contributory rate of the top five polluting countries from 1991 to 2030.

The top five countries accounted for 15 percent of the total increase in pollution between 2016 and 2030 after the signing of the Paris Agreement.

ETH Zurich researcher Lee Bosch, lead author of the study, said: “Our work shows that by 2030, the world will experience extreme heat due to the world’s top five most polluting economies in a very short period of time.” We are talking here about a temperature that was felt once every hundred years before the industrial period will now be felt once every two years.

The United States is the most polluting country in the world and also at the forefront of pollution per capita. Now, if the per capita pollution standards set by the US follow those of other polluting countries, by the end of 2030 the temperature will be 0.4 °C above the current pollution reduction target.
