Rising global temperatures due to the burning of fossil fuels have caused severe droughts across the Northern Hemisphere. Rivers have dried up, and unprecedent wildfires have led to widespread crop failure. According to a new study by World Weather Attribution that examined the link between rising average global temperature and extreme weather, such an occurrence would normally be considered a 1-in-400-year experience. However, due to climate change, it is likely to be repeated every 20 years, which means that extreme weather is 20 times more likely.
