In the past few months United Nations-sponsored negotiations to tackle climate change, plastic pollution, loss of global species and a growing number of deserts have either outright failed or come out with limited outcomes that didn’t address the scale of the problems.

The United Nations climate chief says humanity has only two years left “to save the world” by making dramatic changes in the way it spews heat-trapping emissions.

A new accounting of carbon dioxide emissions finds that heat-trapping gas pollution from fossil fuels went up about 1% more than last year.

Ten years ago scientists warned the world about how climate change would amplify extreme weather disasters.

A new United Nations report says cutting methane pollution is crucial to curbing dangerous climate change in the short term.
