Renewables offer quick fix for US emissions

The US could reduce greenhouse gas emissions from electricity generation by 80% below 1990 levels within 15 years just by using renewable sources such as wind and solar energy, according to a former government research chief. The nation could do this using only technologies available right now, and by introducing a national grid system connected by high voltage direct current […]

Planet Has More Trees

Planet Has More Trees

The last study showed that the world has about 3 trillion trees.  That is over the estimate of 400 billion in previous studies.  Researchers did a count by actually going out and physically counting trees, using satellite imagery, ground survey, and national forest inventories.  Even though we have lost trees from fires, drought, and insect outbreaks there are still more […]

New framework sheds light on how, not if, climate change affects cold-blooded animals

Cold-blooded animals like lizards, insects and fish have a preferred body temperature range at which they hunt, eat, move quickly and reproduce. Fear that a warming climate will constrict this temperature range underlies recent studies that warn of the detrimental effects of climate change on the activity and survival of cold-blooded animals. While not contradicting these warnings, a new paper […]

Ancient fossil forest unearthed in Arctic Norway

UK researchers have unearthed ancient fossil forests, thought to be partly responsible for one of the most dramatic shifts in Earth’s climate in the past 400 million years. The fossil forests, with tree stumps preserved in place, were found in Svalbard, a Norwegian archipelago situated in the Arctic Ocean. They were identified and described by Dr Chris Berry of Cardiff […]

Megadrought may grip the Southwest

Megadrought

The Southwest and central Great Plains are likely to be hit in coming decades by the most prolonged megadrought in more than 1,000 years, a new climate study predicts. Scientists from NASA, Columbia University, and Cornell University created a long-term climate model after analyzing historical temperature records, carbon dioxide emissions, and drought trends from tree rings.The record shows that the […]

Climate deal unveiled in Paris, a ‘historic turning point’

Global climate envoys agreed a landmark accord on Saturday, setting the course for a “historic” transformation of the world’s fossil fuel-driven economy within decades in a bid to arrest global warming. At the tail end of the hottest year on record and after four years of fraught U.N. talks often pitting the interests of rich nations against poor, imperiled island […]
