Heat extremes every second year may be felt in most countries: Study

Ground Report | New Delhi: Heat extremes in most countries; Our earth is warming due to anthropogenic greenhouse gas (GHG) emissions. If global emissions continue like this, by 2030, temperatures will rise by more than 2 degrees Celsius. Emissions continue to rise as the world's largest polluter. Every country around the world could experience extreme warm years every other year by 2030, according to new research.

The researchers found that 92% of the 165 countries studied expect extremely hot annual temperatures every two years, defined as the warmest year of the industrial age once in 100 years.

Alexander Knowles of Climate Analytics, co-author of the study, published in the journal Communications Earth and Environment, said it was "amazing" in itself. "It really reflects the urgency and how we are going to go into a world that is so hot for everyone," he said.

He added while the changes in the regional climate are very close to what we are going to experience. We are about to experience an increased frequency of these increasingly hot years in our country.

To see the scale of the contribution of the world's five largest emitters in this forecast, the authors looked at what the picture would have been without their emission since 1991, when the Intergovernmental Panel on Climate Change (IPCC) For the first time, human-caused emissions were reported. Governments were warned. Climate change.

According to the forecast, the countries responsible for the world's five largest emissions need to look at the scale of their emissions. Researchers have seen what the world would be like without them since 1991. The study found that the proportion of countries affected by the warmer years would be about 46 percent.

The Intergovernmental Panel on Climate Change (IPCC) has for the first time warned governments about human climate change.

Lee Beach, a lead researcher at the ETH University of Zurich's Institute for Atmospheric and Climate Sciences, said the study was a clear indication of the actions of the top emitters at the regional level.

"I think it's very important because we're usually talking about mass emissions, or global warming, which we know about, but we can't really feel it," he said. "It simply came to our notice then.

Researchers have found the greatest impact in terms of the frequency of extremely hot years in tropical Africa. "Because this is an area that traditionally has a much lower temperature change from year to year, even compared to other regions that are willing to experience moderate average temperatures, it actually Keeps away from the envelope of its well-known climate."

But he said the biggest rise in temperatures is in the northern highlands, which are warming faster than the tropics. The authors emphasize that predictions of peak years may change if countries make significant efforts to reduce pollution.

According to the United Nations Framework Convention on Climate Change (UNFCCC), existing projects will see a 13.7% increase in emissions by 2030, when under the Paris Agreement they will have to fall by almost half to reach a temperature of 1.5C.
