The government's climate report warns of deteriorating US disasters

WASHINGTON (AP) – As California’s catastrophic wild fires return and people rebuild after two hurricanes, a massive new federal report warns that these types of disasters are deteriorating in the United States due to global warming. White House report quietly issued Friday often contradicts President Donald Trump.

The National Climate Review was written long before the fatal fires in California this month and before the hurricanes of Florence and Michael shaved the East Coast and Florida. It says that heat-loaded extremities “have already become more common, intensive, widespread or prolonged.” The report notes in recent years has broken American hazardous weather registry records and costs nearly $ 400 billion since 201


The recent North African wilderness can be attributed to climate change, but it was less of a connection with them in Southern California, co-author William Hohenstein from U.S. Department of Agriculture.

“A warm, dry climate has increased the areas burned in the past 20 years,” he said at a press conference on Friday.

The report is statutory for a few years and is based on more than 1,000 previous research studies. It describes how global warming from coal, oil and gas combustion damages every region of the United States and how it affects different sectors of the economy, including energy and agriculture.

“Climate change transforms where and how we live and present growing challenges to human health and quality of life, the economy and the natural systems that support us,” said the report.

It includes elevated air pollution that causes heart and lung problems, more diseases from insects, the potential of hope in death during heat waves and allergies.

“Annual losses in some economic sectors are expected to reach hundreds of billions of dollars at the end of the century – more than current GDP (GDP) in many US states,” said the report. It will be particularly expensive on the coasts of the country due to rising seas and severe storms, which will lower property values. And in some areas, like parts of Alaska and Louisiana, coastal flows are likely to force people to move.

“We see the things we said would happen, now happen in reality,” said another co-author Katharine Hayhoe from Texas Tech University. “As a climate researcher, it’s almost surreal.”

And Donald Wuebbles, a co-author of the University of Illinois climate scientist, said: “We will continue to see difficult weather conditions become stronger and more intense.”

What makes the report different than others is that it focuses on the United States, then it’s more local and granular.

“All climate change is local,” said Pennsylvania State University climate researcher Richard Alley, who was not part of the report but praised it.

While researchers talk about average global temperatures, people feel more extreme, he said.

“We live in our drought, our floods and our heat waves. That means we need to focus on us,” he said.

The lower 48 states have heated 1.8 degrees (1 degrees Celsius) since 1900 by 1.2 degrees in recent decades, according to the report. By the end of the century, the US will be 3 to 12 degrees (1.6 to 6.6 degrees Celsius) warmer depending on how much greenhouse gases are released into the atmosphere, warns the report.

Outside researchers and officials from 13 federal authorities wrote the report released in the afternoon after Thanksgiving. It was originally planned for December. The report often collides with the President’s previous statements and tweets about the legitimacy of climate change science, how much it is caused by people, how cyclical it is and what causes increases in recent fires.

Trump tweeted this week about the cold weather that hit the east, including: “Brutal and Extended Cold Blast can crush ALL RECORDS – Whatever happened to global warming?”

Friday report seemed to anticipate such comments and said: “Over a shorter time scale and less geographical areas, the impact of natural variation may be greater than the impact of human activity … Over the climate schedules of decades, though global temperatures continue to increase steadily.”

Released the report on Black Friday “is an open attempt by Trump Administration to bury this report and continue the campaign not only to deny but suppress the best of climate science,” says co-author Andrew Light, an international policy expert at the World Resources Institute.

During a press conference on Friday, officials behind the report repeatedly responded to questions about how the release date was and why it violates public statements from Trump. Reporting Director David Reidmiller said that questions about the time were “relevant”, but said what was in the report was more important.

Trump, officials and elected Republicans often say they can not tell how much climate change is caused by humans and how much it is natural.

Referring to many studies, the report says that more than 90 percent of the current warming is caused by humans. Without greenhouse gases, natural forces – like changes in energy from the sun – would be something cooling the earth.

“There are no credible alternative human or natural explanations supported by the observation evidence,” the report says.
