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 …

Avoided deforestation has a high value but is hard to prevent without strong regulation and enforcement

Potential for low-cost carbon dioxide removal through tropical reforestation (Nature Climate Change) Removing CO2 from the atmosphere by planting tropical forests could be a “low cost” way of tackling climate change, a study says. The research estimates that CO2 removal from tropical reforestation could be increased by 5% at a cost of $20 per tonne of CO2. However, “avoided deforestation” – leaving forests …

Drones, Seeds, & Fires: How DroneSeed Plants Trees From The Sky

Lessons Learned from Centuries of Indigenous Forest Management

BY RICHARD SCHIFFMAN • AUGUST 20, 2018 In an interview with Yale Environment 360, botanist Charles M. Peters discusses how, in an era of runaway destruction of tropical forests, the centuries-old ecological understanding of indigenous woodland residents can help point the way to the restoration of damaged rainforests. Over centuries, even millennia, indigenous communities have developed interdependent systems of agriculture and forestry that are uniquely suited to …

A better picture of record-setting deforestation

Deforestation:  The World Resources Institute, University of Maryland and associates, as Global Forest Watch, have discovered that 2017 deforestation in the tropics was nearly as large as the record-setting 2016.  The report also notes up to 1/3 of tropical forests down or damaged in areas where the Caribbean hurricanes of 2017 struck. The consequences for natural hazards and disasters include …
