A new study reveals that the Earth's temperature has risen by approximately 1.2 degrees Celsius above pre-industrial levels. The years 2015-2019 were the hottest on record, with an average global temperature increase of 0.2 degrees Celsius per decade. The study warns that if global temperatures continue to rise at the current rate, we could reach the critical threshold of 1.5 degrees Celsius within the next two decades. This increase in temperature has led to more frequent and intense heatwaves, hurricanes, and wildfires around the world. Efforts to reduce greenhouse gas emissions are crucial in order to slow down the pace of global warming and mitigate its catastrophic effects.
