About 12.5 trillion tons (11.3 trillion metric tons) of ice from glaciers in Greenland and Antarctica have melted since 1979, which is enough frozen water to stack ice 5 feet (1.5 meters) deep across the continental United States, according to a major scientific report.

A warming Earth is accelerating the melting of the planet's two major ice sheets, with five-sixths of the melt not coming from hotter air, but from warmer waters eating away at the ice sheets from below and the sides, with glaciers flowing into the oceans, according to a study in Wednesday's journal Scientific Data. That's bad news for future sea level rise, the study's authors said.

Among the dead are five infants, while dozens of people remain trapped beneath the debris," said Mahmoud Bassal, the spokesperson for the civil defense agency, which operates as a rescue force under Hamas authority.

The Trump administration is stripping tens of millions of dollars in U.S. military assistance from countries in Europe and the Middle East to support conservative-leaning governments in Central and South America.

The Trump administration is planning to deliver powerful 2,000-pound bombs to Israel as part of an upcoming arms deal, weapons that prompted such concerns about the possibility of mass casualties in Gaza that the Biden administration paused their delivery two years ago.
