After the resounding clamors on cutting down CO2 emisions to save our planet from getting warmer, a global deal between more than 150 countries has agreed to limit hydrofluoro carbons (HFCs) to combat climate change.
HFCs, used in exchange of CFCs to save the thinning ozone layer, is now getting banned as well. The decision was agreed by participating countries at a summit in Rwanda to resolve the issues of this compounds' hazardous effects to the environment.
When the sun was dimmer, the Earth did not freeze up, and scientists had earlier believed it was because of methane. Now, a new study shatters this long-held assumption.
The infamous “hole in the ozone layer” may be on its way to recovery. Climate scientists have detected “the first fingerprints of healing” in the depleted ozone region over Antarctica.
Researchers say that there has been a 50% drop in one of the hydrochlorofluorocarbons that destroys the ozone layer. They think they know why it has dropped, too.
