WASHINGTON, D.C. — A new US government report delivers a dire warning about climate change and its devastating impacts, saying the economy could lose hundreds of billions of dollars -- or, in the worst-case scenario, more than 10% of its GDP -- by the end of the century.The federally mandated study was supposed to come out in December but was released by the Trump administration on Friday, at a time when many Americans are on a long holiday weekend, distracted by family and shopping.Trump, speaking to reporters Monday, said he doesn't believe the report.David Easterling, director of the Technical Support Unit at the NOAA National Centers for Environmental Information, emphasized that there was "no external interference in the report's development." He added that the climate change the Earth is experiencing is unlike any other."The global average temperature is much higher and is rising more rapidly than anything modern civilization has experienced, and this warming trend can only be explained by human activities," Easterling said.Coming from the US Global Change Research Program, a team of 13 federal agencies, the Fourth National Climate Assessment was put together with the help of 1,000 people, including 300 leading scientists, roughly half from outside the government.It's the second of two volumes. The first, released in November 2017, concluded that there is "no convincing alternative explanation" for the changing climate other than "human activities, especially emissions of greenhouse gases."The report's findings run counter to President Donald Trump's consistent message that climate change is a hoax. On Wednesday, Trump tweeted, "Whatever happened to Global Warming?" as some Americans faced the coldest Thanksgiving in over a century.But the science explained in these and other federal government reports is clear: Climate change is not disproved by the extreme weather of one day or a week; it's demonstrated by long-term trends. Humans are living with the warmest temperatures in modern history. Even if the best-case scenario were to happen and greenhouse gas emissions were to drop to nothing, the world is on track to warm 1.1 degrees Fahrenheit.As of now, not a single G20 country is meeting climate targets, research shows.Without significant reductions in greenhouse emissions, the annual average global temperature could increase 9 degrees Fahrenheit (5 Celsius) or more by the end of this century, compared with preindustrial temperatures, the report says. 2509

WASHINGTON (AP) — President Donald Trump says U.S. military generals have told him that they think the massive explosion that rocked Beirut on Tuesday, killing more than 70 people, was likely a bomb. He told reporters at the White House that he had met with some generals and they do not think it was a manufacturing-type explosion. He says the generals seem to think it was an attack — "a bomb of some kind." The explosion flattened much of a port and damaged buildings across the capital, sending a giant mushroom cloud into the sky. More than 3,000 others were injured, with bodies buried in the rubble. 614
