Ozone Treaty Stopped Jet-Stream Drift in Southern Hemisphere

March 27, 2020

Researchers long ago predicted that the 1987 Montreal Protocol, banning ozone-depleting gases, would reverse a worrisome trend in Southern Hemisphere winds. A new study shows they were right.
Ozone-Depleting Substances Caused Half of Late 20th-Century Arctic Warming, Says Study

January 20, 2020

A study finds that ozone-depleting substances caused about a third of all global warming from 1955 to 2005, and half of Arctic warming and sea ice loss during that period.
Without the Montreal Protocol, More Intense Tropical Cyclones

February 1, 2016

Using one of the most advanced atmospheric computer models available, scientists compared our expected future with a scenario in which ozone-depleting substances had never been regulated.
Bad Ozone Days in Western U.S. Linked to Pacific Weather

May 12, 2015

A new study shows that ozone pollution in the western United States can be increased by La Niña, a natural weather cycle at the surface of the Pacific Ocean. The finding is the first to show that the La Nina-El Nino cycles directly affects pollution.
Have We Crossed the 9 Planetary Boundaries?

“The world needs to awaken itself to the looming catastrophe of global warming,” said Jeffrey Sachs, Director of the Earth Institute, at a recent meeting in Muscat. “We must provide a safe operating space where vested interest and lobby-driven policies will not see the world marching into disaster.”
