International efforts to protect the ozone layer-the shield that protects life on Earth from harmful levels of ultraviolet rays-are a success and have stopped additional ozone losses and contributed to mitigating the greenhouse effect, according to a new report.
Humans have yet to push the planet past the point of no return when it comes to global warming, according to the surprising results of a new study.
It says that if people stopped building carbon dioxide-emitting power plants, factories, vehicles and homes today and allowed existing CO2-emitters to live out their normal lives, catastrophic climate change could likely be avoided.
Unfortunately, the study also notes humans are in no position to say farewell to fossil fuels and concludes "extraordinary" efforts are needed to switch to a carbon-free path.
