The USNS Comfort hospital ship and an emergency hospital at the Javits Center are meant to be relief valves for hospitals in New York City, where more than 14,000 people have been hospitalized for COVID-19. But the facilities have been largely empty, leading officials to try to streamline their operations.

Now, New York Gov. Andrew Cuomo is hoping the Comfort can join the Javits Center on the front line of the fight against the coronavirus.

Medical rationing is not something Americans are accustomed to, but COVID-19 may soon change that.

The specter of rationing is most imminent in New York City, where the virus is spreading rapidly and overwhelming hospitals with patients.

According to New York Gov. Andrew Cuomo, the state has 2,200 ventilators in its state stockpile. Current COVID-19 case projections suggest the state may not have enough of the machines, which help critically ill people breathe, as soon as next week.

Some New York City hospitals are still unable to perform reliable on-site coronavirus testing for patients and staff who show symptoms of COVID-19 and must instead wait days for results from outside laboratories, even as the city's hospital beds fill up with seriously ill people.

New York City hospitals are struggling to make sure they have enough staff, beds and protective equipment to treat a relentless and growing stream of COVID-19 patients. Providing effective, efficient care to people who are seriously ill requires hospitals to rapidly test people who appear to have the viral disease.

But even with New York's statewide effort to procure and distribute coronavirus testing supplies to hospitals, some medical centers say they still don't have what they need to test patients on-site. That includes one major hospital in Brooklyn.

Spring begins today in America. Good.

Perhaps you are mildly surprised to learn that March 19 is the first day of spring. Perhaps you learned as a child that the spring equinox — when day and night are roughly the same length — occurs on either March 20 or March 21.

Opening arguments ended Monday in Texas in the highest profile criminal case ever brought against a company and its employees for allegedly failing to adequately prepare for the effects of climate change.

The company, Arkema, owns a chemical plant outside Houston that flooded when Hurricane Harvey dumped more than 5 feet of rain on the area in 2017. The rising water knocked out power to the plant and caused volatile chemicals stored there to heat up and eventually catch fire. Burning containers and trailers sent up a column of black smoke above the facility for days.

Everyone who lived through Black Saturday remembers the heat and the wind that day in February 2009. The temperature soared to 115 degrees Fahrenheit — so hot it sucked the breath out of you, made your vision swim and your fingers swell. The wind blew in from the northwest, from the vast, arid Australian interior. Flags flew stiff. Fire danger was extreme.

Coming off a shift at Tuen Mun Hospital in Hong Kong on Wednesday night, cardiologist Alfred Wong was getting ready to go to dinner with his wife. The last time they ate together, she brought the meal to the courtyard below their apartment, placed it on a bench, then sat down at least 10 feet away.

From across the patio, they ate. On separate benches. Looking at each other.

First came the fires, denuding millions of acres of forest in eastern Australia. Now comes the rain, more than 12 inches in just 48 hours over this past weekend in some areas of New South Wales.

That sequence, severe bushfires followed by torrential rain, is bringing a third cataclysm — landslides and large-scale erosion.

Last year was the second hottest on record globally, according to the latest climate data collected by the National Oceanic and Atmospheric Administration and NASA.

It's the latest confirmation that the Earth is steadily getting hotter — the planet has already warmed about 1.8 degrees Fahrenheit (or almost 1 degree Celsius) compared with in the mid-20th century — and that robust greenhouse gas emissions are causing global warming to continue unabated.

Embers are raining down on communities across Australia.

In early March, people who live along Mozambique's long coastline began to hear rumors about a cyclone.

The storm was forming in the Indian Ocean, in the narrow band of warm water between Mozambique and the island of Madagascar. Overnight on March 14, 2019, the storm struck Mozambique head-on, barreling over the port city of Beira and flooding an enormous swath of land as it moved inland toward Zimbabwe.

Normal November weather in Mozambique's capital, Maputo, is pleasant and warm with a chance of epic thunderstorms. The sun will be shining in the morning, and then boom the sky opens up and a stiff wind begins to blow and it's probably best if you're inside.

Greenhouse gas emissions have risen steadily for the past decade despite the current and future threat posed by climate change, according to a new United Nations report.

The annual report compares how clean the world's economies are to how clean they need to be to avoid the most catastrophic effects of climate change — a disparity known as the "emissions gap."

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.

Lead-based paint was extremely popular in the early and mid-20th century — used in an estimated 38 million homes across the U.S. before it was banned for residential use in 1978.

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.

People across southern Louisiana are spending the weekend worried about flooding. The water is coming from every direction: the Mississippi River is swollen with rain that fell weeks ago farther north, and a storm called Barry is pushing ocean water onshore while it drops more rain from above.

It's a situation driven by climate change, and one that Louisiana has never dealt with, at least in recorded history. And it's raising questions about whether New Orleans and other communities are prepared for such an onslaught.

Sea levels are rising, and that is sending more ocean water into streets, sewers and homes. For people who live and work in coastal communities, that means more otherwise-sunny days disrupted by flooding.
