Arctic Ozone Depletion Reached Record Level

Depletion of the ozone layer, ­the shield that protects life on Earth from harmful levels of ultraviolet radiation, reached an unprecedented level over large parts of the Arctic this spring. This phenomenon was caused by the continuing presence of ozone­-depleting substances in the atmosphere and a very cold winter in the …

Signs and Impacts of Climate Change in Atmosphere, Land and Oceans Are Rising

The tell-tale physical signs of climate change such as increasing land and ocean heat, accelerating sea level rise and melting ice are highlighted in a new report compiled by the World Meteorological Organization and an extensive network of partners. It documents impacts of weather and climate events on socio-economic development, …

Submarine to Explore Why Antarctic Glacier Is Melting so Quickly

An international team of scientists has reached the Thwaites glacier in Antarctica and is preparing to drill through more than half a kilometre of ice into the dark waters beneath. The 600-metre deep borehole will allow researchers to lower down a torpedo-shaped robotic submarine that will explore the underside of …

Ozone Layer Finally Healing After Damage Caused by Aerosols, UN Says

The ozone layer is showing signs of continuing recovery from man-made damage and is likely to heal fully by 2060, new evidence shows. The measures taken to repair the damage will also have an important beneficial effect on climate change, as some of the gases that caused the ozone layer …

Five Countries Hold 70% of World’s Last Wildernesses, Map Reveals

Just five countries hold 70% of the world’s remaining untouched wilderness areas and urgent international action is needed to protect them, according to new research. Researchers from the University of Queensland (UQ) and the Wildlife Conservation Society (WCS) have for the first time produced a global map that sets out …

Rising Ocean Waters from Global Warming Could Cost Trillions of Dollars

Ocean waters are rising because of global warming. They are rising for two reasons. First, and perhaps most obvious, ice is melting. There is a tremendous amount of ice locked away in Greenland, Antarctica, and in glaciers. As the world warms, that ice melts and the liquid water flows to …
