The Trump administration has formally notified the United Nations that the U.S. is withdrawing from the Paris climate agreement. The withdrawal will be complete this time next year, after a one-year waiting period has elapsed.

"We will continue to work with our global partners to enhance resilience to the impacts of climate change and prepare for and respond to natural disasters," Secretary of State Mike Pompeo said in a statement Monday.

Kurds in northern Syria have announced an abrupt change in alliances in the wake of President Trump's decision to withdraw U.S. forces from the area.

American soldiers had been supporting Kurdish fighters, as part of the U.S. military's operations against Islamic extremists in the region. But, with the U.S. already withdrawing, neighboring Turkey has launched an operation against Kurds in Syria, who they argue are terrorists.

Typhoon Hagibis slammed into Japan over the weekend, dropping more than 35 inches of rain in some places and causing catastrophic flooding in communities in the region around Tokyo, as well as further inland.

A broad analysis of federal records finds that homeowners hoping to relocate out of flood zones in the U.S. don't have equal access to the main source of federal funding meant to help them.

As the world's climate changes, ocean warming is accelerating and sea levels are rising more quickly, warns a new report by the U.N. Intergovernmental Panel on Climate Change.

The report is a synthesis of the most up-to-date climate science on oceans and ice, and it lays out a stark reality: Ocean surface temperatures have been warming steadily since 1970, and for the past 25 years or so, they've been warming twice as fast.

Leaders from nearly 200 countries are attending a special United Nations Summit on climate change today as they face increasing pressure from citizens around the world to cut global greenhouse gas emissions and slow global warming.

Currently, global emissions are on track to cause potentially catastrophic climate change in the coming decades.

The firefighters came on Monday. They went up and down the halls, knocking on every apartment in the six-story Ansonborough House building in downtown Charleston, S.C., and leaving notices on the doors of those who didn't answer: This area is under mandatory evacuation.

The manager of the building heeded the warning and left a note on the window in the lobby explaining that the building would not be staffed all week.

If you want to know what climate change will look like, you need to know what Earth's climate looked like in the past — what air temperatures were like, for example, and what ocean currents and sea levels were doing. You need to know what polar ice caps and glaciers were up to and, crucially, how hot the oceans were.

Humans must drastically alter food production to prevent the most catastrophic effects of global warming, according to a new report from the United Nations panel on climate change.

The panel of scientists looked at the climate change effects of agriculture, deforestation and other land use, such as harvesting peat and managing grasslands and wetlands. Together, those activities generate about a third of human greenhouse gas emissions, including more than 40% of methane.

It technically began last fall when Hurricane Florence swelled the Ohio River, but really it was all the unnamed storms that came after it — one after another after another, bringing rain on rain on rain across the central U.S. until the Mississippi River hit flood stage this winter.

Much of the Mississippi, and the massive tributaries that feed it, stayed flooded until June. That meant more than 140 days of cascading disasters for hundreds of small towns from Minnesota to Louisiana and catastrophic damage to ranch and farm communities that dot the Mississippi's swollen branches.

The global shipping industry is enormous — thousands of ships carry billions of dollars of goods each year across nearly every ocean on the planet.
