Dust from a giant asteroid crash caused an ancient ice age

About 466 million years ago, long before the age of the dinosaurs, the Earth froze. The seas began to ice over at the Earth's poles, and the new range of temperatures around the planet set the stage for a boom of new species ...

Green material for refrigeration identified

Researchers from the UK and Spain have identified an eco-friendly solid that could replace the inefficient and polluting gases used in most refrigerators and air conditioners.

What does global climate have to do with erosion rates?

For the last several decades, geoscientists have been intrigued by a potential link between erosion rates at the Earth's surface and changes in global climate. Distinguishing the cause and effect remained unclear. However, ...

Thin tropical clouds cool the climate

Thin clouds at about 5 km altitude are more ubiquitous in the tropics than previously thought and they have a substantial cooling effect on climate. This is shown in a recent study by researchers from Stockholm University ...

Did a burning oil spill wipe out the dinosaurs?

Sixty six million years ago, the dinosaurs suddenly disappeared, along with most of the species on the planet. The extinction occurred at precisely the same time that a giant asteroid struck the Earth. The fact that the two ...

Deforestation is messing with our weather and our food

Today, the National Socio-Environmental Synthesis Center (SESYNC) at the University of Maryland published new research in Nature Communications providing insight into how large-scale deforestation could impact global food ...

Global cooling

Global cooling was a conjecture during the 1970s of imminent cooling of the Earth's surface and atmosphere along with a posited commencement of glaciation. This hypothesis never had significant scientific support, but gained temporary popular attention due to a combination of press reports that did not accurately reflect the scientific understanding of ice age cycles, and a slight downward trend of temperatures from the 1940s to the early 1970s. General scientific opinion is that the Earth has not durably cooled, but undergone global warming throughout the 20th century.
