A new study funded by NASA has found that Amazon forests are losing their greenness due to last year's record-breaking drought. "The greenness levels of Amazonian vegetation -- a measure of its health -- decreased dramatically over an area more than three and one-half times the size of Texas and did not recover to normal levels, even after the drought ended in late October 2010," Liang Xu of Boston University and the study's lead author said in a statement. Researchers used computer models...

Forest fires usually spread out of control very quickly. Fires that produce a lot of smoke are particularly challenging for the emergency services, because the source of the fire is then especially hard to find. A new radiometric sensor can pinpoint the heart of the flames, even when visibility is limited. The number and scale of forest fires has increased dramatically in recent decades. Who can forget last summer's television images of blazing infernos devouring miles and miles of forest in...

New research indicates that the speed of early forest clearance following human colonisation of the South Island of New Zealand was much faster and more intense than previously thought. Charcoal recovered from lake-bed sediment cores show that just a few large fires within 200 years of initial colonization destroyed much of the South Island's lowland forest. Grasslands and shrubland replaced the burnt forest and smaller fires prevented forests from returning. The findings - by an...
