Solo: Forests nationwide are feeling the heat from increasing drought and climate change, according to a new study by scientists from 14 research institutions. Drought-induced forest diebacks, bark beetle infestations and wildfires are already occurring on large scales across the West, and many models predict droughts are likely to become more severe, frequent and prolonged across much of the United States. The study notes that the impact of drought and climate change are profound in the West US,...

Guardian: Africas tropical forests are threatened by a palm oil bonanza that has already razed millions of old-growth hectares in south-east Asia, Greenpeace France warned on Tuesday. The NGO called on European palm and rubber plantation giant Socfin, which controls vast tracts of tropical land in more than half-a-dozen African nations, to join other multinationals in adopted so-called zero deforestation policies. Dozens of global companies - GAR, Cargill, and Agropalma among commodity producers,...
How climate change may be impacting the world's tropical forests

EurekAlert: New research suggests that multi-year droughts will significantly alter the structure, composition, and dynamics of second-growth tropical forests, which have re-grown after cessation of agricultural activity or a major disturbance such as fire. These second-growth forests represent the prevalent tropical forest cover today. Investigators combined 14 years of data on annual tree growth and survival with local climate records in the Caribbean lowlands of Costa Rica to evaluate tree responses to inter-annual...

Mongabay: Agriculture in Argentina has expanded at an accelerated rate in the past twenty years due to technological advances, the use of genetically modified crops, and, in particular, to the cultivation of soybean. The South American country is the first global exporter of soy, and the biggest provider of flour and biodiesel made from its derivates; the crop is an important source of income. However, according to the coordinator of Greenpeaces forest campaign in Argentina, Hernán Giardini, the advance...

[NEWS] There's no question that our species has had a dramatic impact on the planet's physical environment, particularly over the last few centuries, with the rise of modern industry, transportation, and infrastructure. But as new research shows, humans have been transforming the landscape, with lasting impacts, since long before the start of the Industrial Era. Scientists from MIT and the University of Massachusetts at Amherst have found that a widespread and permanent loss…
