Extreme wildfires may increase by 14 percent by 2030, even with deep cuts to greenhouse gas emissions
Uncontrollable wildfires are intensifying with the rise in greenhouse gas emissions, according to a sweeping global report released Wednesday by the United Nations Environment Program and nonprofit GRID-Arendal, and communities are not prepared for the escalating damage.Even with deep cuts to greenhouse gas emissions, the U.N. analysis projected the risk for these extreme wildfires would rise 14 percent by 2030 and 30 percent by 2050. By the end of the century, risk would increase by 50 percent.
That may include flames that are leaping from tree canopies or those that crawl through peatlands but still emit a tremendous amount of carbon into the atmosphere. Wet forest ecosystems in South America and other regions are seeing unusual fire activity because of human activities such as logging, road construction, agriculture and mining. The loss of tree canopy in disturbed forests promotes the growth of fuels on the forest floor; these exposed then dry out quickly, and are vulnerable to fire spread. Recent studies have shown a staggering loss of trees and biodiversity following fires in wet forests.
“We’re spending an enormous amount of money on suppression, particularly in the developed world,” said Peter Moore, an author of the report and a forestry officer with the Food and Agriculture Organization of the United Nations. “That solution has run its course — in my opinion, it’s reached its limits.”In addition to curbing greenhouse gas emissions, the most effective
