Each degree of warming causes way more fire than the previous degree of warming did: California’s Wildfires Are 500 Percent Larger Due to Climate Change. Current emissions path would wipe out forests.

“Each degree of warming causes way more fire than the previous degree of warming did. And that’s a really big deal,” Park Williams, a climate scientist at Columbia University and an author of the paper, told me. Every additional increment in heat in the environment speeds up evaporation, dries out soil, and parches trees and vegetation, turning them into ready …

With Poorest and Laborers Bearing the Brunt, Report Warns Searing Temperatures of Global Heating Could Cost World Economy $2.4 Trillion by 2030

The importance of cutting emissions was highlighted by a new study this week about the risk of rising heat deaths in US cities. The research, published in Science Advances, finds that limiting global temperature rise to 1.5C above pre-industrial levels, rather than 2C or 3C, could help prevent thousands of deaths during heatwaves. For example, in a 1.5C warmer world, …

Hamburg’s Green Roads, bike paths and green space linkages
