Only 13 of the world's countries and territories had "healthy" air quality last year, according to a new report, as air pollution surged to alarming levels in 2022.

Against the backdrop of the water crisis in the Colorado River Basin, where the country's largest reservoirs are plunging at an alarming rate, California's two largest reservoirs — Shasta Lake and Lake Oroville — are facing a similar struggle.

The annual "adaptation gap" report — which published Thursday amid the COP26 climate summit in Glasgow — found that the estimated costs to adapt to the worst effects of warming temperatures such as droughts, floods and rising seas in low-income countries are five to 10 times higher than how much money is currently flowing into those regions.

For the first time on record, precipitation on Saturday at the summit of Greenland — roughly two miles above sea level — fell as rain and not snow.

The climate crisis is accelerating at unprecedented pace, according to a new United Nations state-of-the-science report. It is "a code red for humanity," said UN Secretary-General António Guterres — and given that the report concludes the entirety of the warming is due to human greenhouse gas emissions, avoiding the worst of its consequences is up to us.

As the world battles historic droughts, landscape-altering wildfires and deadly floods, a landmark report from global scientists says the window is rapidly closing to cut our reliance on fossil fuels and avoid catastrophic changes that would transform life as we know it. The state-of-the-science report from the United Nations' Intergovernmental Panel on Climate Change says the world has rapidly warmed 1.1 degrees Celsius higher than pre-industrial levels, and is now careening toward 1.5 degrees — a critical threshold that world leaders agreed warming should remain below to avoid worsening impacts.
