There is enough room in the world’s existing parks, forests, and abandoned land to plant 1.2 trillion additional trees, which would have the CO2 storage capacity to cancel out a decade of carbon dioxide emissions, according to a new analysis by ecologist Thomas Crowther and colleagues at ETH Zurich, a Swiss university.

Tropical Depression 02W has organized and strengthened into a tropical storm.

Fossil fuel combustion is the main contributor to black carbon collected at five sites around the Arctic, which has implications for global warming, according to a study by an international group of scientists that included a team from Baylor University.

A major volcanic event could have triggered one of the largest glaciations in Earth's history – the Gaskiers glaciation, which turned the Earth into a giant snowball approximately 580 million years ago. 

Simply protecting small forests will not maintain the diversity of the birds they support over the long run, a Rutgers-led study says. 

The mesoscale activities (or mesoscale structures) in the ocean possess huge energy. 

The ice‐covered season plays an important role in the development of river channels, a new study from the University of Eastern Finland shows. 

When a stream of charged particles known as the solar wind careens onto the Moon’s surface at 450 kilometers per second (or nearly 1 million miles per hour), they enrich the Moon’s surface in ingredients that could make water, NASA scientists have found.

Total human carbon dioxide emissions could match those of Earth’s last major greenhouse warming event in fewer than five generations, new research finds.

Tropical Cyclone Oma appeared well-organized on satellite imagery as it moved through the Southern Pacific Ocean, just northwest of New Caledonia.
