Extreme heatwaves and heavy rain storms are already happening with increasing regularity worldwide because of manmade climate change, according to new research.
Global warming over the last century means heat extremes that previously only occurred once every 1,000 days are happening four to five times more often, the study published in Nature Climate Change said.
It found that one in five extreme rain events experienced globally are a result of the 0.85C global rise in temperature since the Industrial Revolution, as power plants, factories and cars continue to pump out greenhouse gas emissions.
Future warming will bring a more volatile, dangerous world, even if the world manages to keep temperature rises within a 2C limit to which governments have committed, Fischer’s research found. On average, any given place on Earth will experience 60% more extreme rain events and 27 extremely hot days....
“The increased probability of high rainfall events will enhance the adverse impacts of these events in many parts of the world, particularly for vulnerable communities. For example short bursts of intense rainfall in Dhaka already cause huge traffic jams and misery for its citizens,” he said.
