'The effects of climate change on extreme heat have amplified underlying inequality, disproportionately harming low-income, low-emitting regions,' say the authors of a new study.
"The effects of climate change on extreme heat have amplified underlying inequality, disproportionately harming low-income, low-emitting regions."A study published Friday revealed that heatwaves fueled by human-caused climate change have cost the global economy trillions of dollars over the past 30 years, with the world's poorest countries—and those least responsible for the climate emergency—bearing a disproportionate share of the burden.
"The regions with the lowest incomes globally are the ones that suffer most from these extreme heat events.", reached three key conclusions. First,"increased extreme heat intensity significantly decreases economic growth in relatively warm tropical regions and weakly affects it in relatively cool midlatitude regions." Second,"anthropogenic climate change has increased the frequency and intensity of these economically consequential heat extremes.
"Accelerating adaptation measures within the hottest period of each year would deliver economic benefits now," study first author Christopher Callahan, a doctoral candidate in geography at Dartmouth College in New Hampshire, said in a ."The amount of money spent on adaptation measures should not be assessed just on the price tag of those measures, but relative to the cost of doing nothing. Our research identifies a substantial price tag to not doing anything.":"No one has shown an independent fingerprint for extreme heat and the intensity of that heat's impact on economic growth. The true costs of climate change are far higher than we've calculated so far.
"The regions with the lowest incomes globally are the ones that suffer most from these extreme heat events," Mankin added."As climate change increases the magnitude of extreme heat, it's a fair expectation that those costs will continue to accumulate."
