Amazon rainforest likely to become savannah due to burning, deforestation, climate change

by Jeremy Hance A new analysis shows that the heavily-deforested Amazonian region of Mato Grosso is particularly susceptible to ‘savannization’ due to repeated burning that has likely depleted the region’s soils of precious nutrients. According to the study, published in the Journal of Geophyscial Research, savannization, or the process of tropical ecosystems shifting to savannah, […]

Hell and high water: The global warming impacts of business-as-usual

by Joe Romm In this post, I will examine the key impacts we face by 2100 if we stay anywhere near our current emissions path. I will focus primarily on: Staggeringly high temperature rise, especially over land — some 15°F over much of the United States Sea level rise of 5 feet, rising some 6 […]

1500 Northern Australia species face extinction

  By Tara Ravens NORTHERN Australia is facing a fresh wave of potentially catastrophic mammal extinctions, experts warn. Australia has the worst mammal extinction record in the world, with 22 mammals becoming extinct in the last 200 years. Scientists now say the evidence suggests Australia is on the cusp of another wave. Over 40 scientists […]

Most southern hemisphere plant species face extinction

by Deborah Smith, Science Editor MOST southern hemisphere plants – except for weeds – will not be able to adapt to rapid climate change, a study of more than 11,000 species suggests. Researchers, including the Sydney botanist Peter Weston, traced the history of plants that live in a range of different habitats including bogs, alpine […]

Dramatic expansion of dead zones in the oceans

(University of Copenhagen) Unchecked global warming would leave ocean dwellers gasping for breath. Dead zones are low-oxygen areas in the ocean where higher life forms such as fish, crabs and clams are not able to live. A team of Danish researchers have now shown that unchecked global warming would lead to a dramatic expansion of […]

A billion frogs on world's plates, accelerating amphibian extinctions

Up to one billion frogs are taken from the wild for human consumption each year, according to a new study. Researchers arrived at this conclusion by analysing UN trade data, although they acknowledge there is a lot of uncertainty in the figure. France and the US are the two biggest importers, with significant consumption in […]

Mass die-off of western U.S. forests due to climate change

Death Rates Have Doubled, Researchers Find By Juliet Eilperin, Washington Post Staff Writer The death rates of trees in western U.S. forests have doubled over the past two to three decades, driven in large part by warmer temperatures and water scarcity linked to climate change, a new study spearheaded by the U.S. Geological Survey has […]

Fifth of world's corals already dead, say experts

POZNAN, Poland (AFP) – Almost a fifth of the planet’s coral reefs have died and carbon emissions are largely to blame, according to an NGO study released Wednesday.
