NYT on models based study: For this latest study, Dr. Burke, along with Noah Diffenbaugh, a climate scientist, looked at more than 20 climate models to estimate how much countries have warmed since 1960 specifically because of climate change. Then, they estimated what each country’s economic performance could have been without such a temperature rise.
Most of the world’s poor countries are poorer today than they would have been had those emissions not altered the climate, while many rich countries, especially in the northern belt of the Northern Hemisphere, are richer than they would have been, the study found.
Between 1961 and 2000, climate change dampened per capita incomes in the world’s poorest countries by between 17 percent and 30 percent. Among the countries hardest hit were also some of the largest. India, the world’s second most populous country, would have been 30 percent richer without climate change, the study concluded. For Nigeria, the most populous country in Africa, that figure was 29 percent.
A screaming lack of enthusiastic media coverage regarding recent evidence that Jakobshavn, the previously fastest-flowing, fastest-thinning glacier on Greenland’s west coast, has now gone rogue. Jakobshavn has represented the largest source of periodic ice mass loss over the last 20 years, and has produced about 10 percent of the country’s icebergs.
A study published last month in the journal Nature reported, "Here we use airborne altimetry and satellite imagery to show that since 2016, Jakobshavn has been re-advancing, slowing and thickening. We link these changes to current cooling in ocean waters in Disko Bay that spill over into Ilulissat Icefjord. Ocean temperatures in the bay’s upper 250 meters have cooled to levels not seen since the mid-1980s."
