2021 a record hot year for almost 2 billion people

‘Science leaves no room for doubt: climate change is the existential threat of our time’Nearly a quarter of the world’s population experienced a record hot year in 2021, according to data from climate experts, as temperatures continue to escalate around the globe in an ongoing environmental crisis. “Science leaves no room for doubt: climate change is the existential threat of our time,” said NASA administrator Bill Nelson, The Guardian reported. While 2021 did not exceed the record heat set in 2020, scientists said last year was another example of the long-term global heating caused by human activity, such as burning fossil fuels and deforestation. According to the climate NGO Berkeley Earth, a total of 1.8 billion people — almost a quarter of the world’s population — faced the hottest year on record in 2021, including in China, Nigeria, and Iran. 2022 will likely be one of the 10 hottest years ever, with a small chance of it being the warmest year on record, Vose noted.
