Tropical forests account for a third of the total carbon fixed by photosynthesis. Lianas’ increasing abundance may be driven by changing climate, increased disturbance or by more severe seasonal drought. By reducing the ability of tropical forests to accumulate and store carbon released through burning fossil fuels, lianas could cause a positive feedback loop, accelerating climate change. “This study has […]

When spring arrives in the Arctic, both snow and sea ice melt, forming melt ponds on the surface of the sea ice. Every year, as global warming increases, melting sea ice leads to more and larger melt ponds. Melt ponds provide more light and heat for the ice and the underlying water, but now it turns out that they may […]

Climate change, not just increasing atmospheric temperatures, has been affecting the Jet Stream. When the Jet Stream travels across from the West to the East over the Northern Hemisphere in normal conditions the weather is not greatly affected, but because of the climate change it has been slowing down and causing massive heat waves and flooding. When the jet stream […]

Across the world, bats are in trouble from climate change – not only through collisions with the wind turbines that are intended to mitigate its effects, but from what the increasing warmth does to their ability to find their prey. Bats often get a bad press, portrayed as disease-spreading bloodsuckers. In fact, they perform a vital role as pollinators, seed […]

Climatologists found that the carbon dioxide levels have risen so high that they could have catastrophic consequences to our life on the planet earth. Prior to the 18th century the levels were averaging about 280 ppm (parts per million). The Industrial Revolution began burning fossil fuels which sent more carbon dioxide into the atmosphere. They are predicting that our carbon […]

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 […]

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 […]

On September 13, 1922, a temperature of 136°F was recorded at El Azizia, Libya. This was eventually certified by the World Meteorological Organization as the hottest air temperature ever recorded on Earth. The hottest air temperature ever recorded in the United States was on July 10, 1913 where it reached 134 in Furnace Creek, Death Valley, California. NASA scientists report […]

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 […]

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 […]
