Global Temperature Analysis: The World Meteorological Organization (WMO) said in its new analysis of global temperatures on Wednesday (17 May) that global warming will cross the threshold of 1.5 degrees Celsius for the first time in the next 5 years. It said the 1.5 degree Celsius temperature limit could be breached, at least temporarily, over the next five years.
According to an Indian Express report, a WMO analysis says there is a 66 percent chance of global warming of 1.5 degrees Celsius or more than the pre-industrial average in at least one year between 2023 and 2027. Also, there is a 98 percent chance that one of these years will surpass 2016 as the warmest year on record.
2016 is now believed to be the hottest year on record. The annual mean temperature for that year was 1.28 °C higher than in pre-industrial times (average for the period 1850–1900). At the same time, last year (2022) was 1.15°C warmer than the pre-industrial average.
Separately, a new study released on Wednesday said climate change may be largely responsible for the intense heat wave that hit India and some neighboring countries in April.
Heat waves in India, Bangladesh, Laos and Thailand are at least 30 times more likely in April due to climate change, according to a report released by a group of researchers associated with the World Weather Attribution Initiative. He said that such events were supposed to happen once in a hundred years, but are now likely to happen once every five years due to climate change.
The WMO said the average annual temperature for the next five years is expected to be 1.1 to 1.8 degrees Celsius above the pre-industrial average. If the rising temperature trend is halted immediately, the breach of the 1.5°C temperature limit could become permanent very soon.
