Trends in U.N. climate report point to an altered Chesapeake Bay.

Climate change is clearly observable in every region of the planet, and the window is closing for nations to take actions that would stem the most severe future impacts, a global climate assessment concluded in August.

The report, compiled by more than 230 scientists who assessed more than 14,000 studies, cautioned that world leaders are rapidly running out of time to limit global warming to 1.5 degrees Celsius from preindustrial levels.

Many of the changes now observed are unprecedented in thousands, if not hundreds of thousands, of years of climate records, said the latest report from the Intergovernmental Panel on Climate Change, which was created by the United Nations in 1988 and is considered an authority on global climate issues.

Even with quick action, the panel warned, that changes already set in motion — such as sea level rise — are irreversible over hundreds to thousands of years because it takes so long to counter alterations already taking place in the oceans that cover three-quarters of the planet.

Still, the report said that strong and sustained actions to curb emissions of carbon dioxide and other greenhouse gases would limit impacts of climate change, but it could take 20–30 years to see global temperatures stabilize.
