Carbon rise keeps water in drylands

The drylands of the world are getting greener, and researchers think it is thanks to higher levels of carbon dioxide in the atmosphere. In a paradoxical discovery, even as landscapes become increasingly at risk of desertification, they may also look more luxuriant. Two scientists from Purdue University in Indiana, US, and a researcher in Saudi Arabia report in the journal […]

Oxygen-starved oceans held back life’s recovery after the ‘Great Dying’

Stanford scientists have found that chronically low levels of oxygen throughout the oceans hampered the recovery of life after the Permian-Triassic extinction, the most catastrophic die-off in our planet’s history. Also known as the “Great Dying,” global ecosystems collapsed as some 90 percent of species perished in this extinction event 250 million years ago. The new findings, published this week […]

The Arctic’s ozone hole

The ozone layer over the Arctic Circle developed a giant hole this winter, scientists say. Over the North Pole, 40 percent of the ozone layer has disappeared—a record seasonal loss. Ozone high in the atmosphere shields the Earth from harmful UV rays, and it fluctuates seasonally; usually about 25 percent of the Arctic’s ozone layer fades every winter. In the […]

Products From China Not Good For The Environment

In a study published in the journal Nature Climate Change, scientists from three universities show that products made in China are associated with significantly higher carbon dioxide emissions than the same products made elsewhere. “The amazing increase in Chinese manufacturing over the past 15 years has driven the world economy to new heights and supplied consumers in developed countries with […]
