Record-size Hole Opens in Ozone Layer Above the Arctic

A rare hole has opened up in the ozone layer above the Arctic, in what scientists say is the result of unusually low temperatures in the atmosphere above the north pole. From a report: The hole, which has been tracked from space and the ground over the past few days, has reached record dimensions, but is not expected to pose any…

A rare ozone hole is open over the Arctic

Since March 14, ozone over Earth’s Arctic has decreased to what’s normally considered ‘ozone hole levels.’ Scientists expect this year’s Arctic hole – the largest ever seen over the Arctic – to close again around mid-April 2020.

How To Get To Net Zero Carbon Emissions: Cut Short-Lived Superpollutants

Dan Drollette writes: We absolutely, positively, must tackle climate change speedily. Or as the authors of this article put it: ‘By ‘speed,’ we mean measures — including regulatory ones — that can begin within two-to-three years, be substantially implemented in five-to-10 years, and produce a climate response within the next decade or two.’ (Quick aside: one of the authors, Mario Molina,…

The ozone layer is healing and redirecting wind flows around the globe

What Earth’s changing climate can teach us about altering the surface of Mars

In a rare instance of environmental success, the United Nations has just announced it believes the damage to the Earth’s protective ozone layer will be fully restored by the year 2050. This stands in stark contrast to the increasing alarm over the climate emergency, caused by an increasing greenhouse effect. Source: https://phys.org/news/2019-09-earth-climate-surface-mars.html…

The Ozone Layer Is On Track To Completely Repair Itself by the 2060s

pgmrdlm quotes a report from SBS: The world’s ozone layer is on track to be completely healed by the 2060s, according to modelling by the UN’s environmental agency (UNEP). In the past 19-years, parts of the ozone layer have recovered at a rate of one to three per cent every ten years, UNEP has found. If this continues, the Northern Hemisphere’s…
