New Report Reignites Climate Change Debate Within US Gov't

We speak with Kristie Ebi, a professor of global health at the University of Washington in Seattle and the lead author of the report's chapter on the human health impacts of climate change.

The report's release comes as Democrats in Congress plan to restore the so-called Climate Change Committee in an alleged attempt to ramp up pressure on Republican President Donald Trump.

The report assigns specific expenses to the monumental effects of a warming planet, finding that climate change could slash up to a 10th of the United States' gross domestic product (GDP) by 2100.

The report, which was written before California's recent deadly fires, also says the last few years have smashed records for damaging weather in the US, costing almost $400 billion since 2015.

NCA4 Volume I: Climate Science Special Report presents an assessment of the physical science underlying this report.

The congressionally mandated White House report said climate change would cost the U.S. economy billions of dollars by the end of the century, but Mr Trump said on Monday (local time) he did not believe the economic impacts would be destructive.

"And this warming trend can only be explained by human activities, especially emissions of greenhouse gases into the atmosphere".

The United Nations report issued in October was issued by the Intergovernmental Panel on Climate Change.

Thirteen federal agencies and more than 300 authors produced the report; their work stretched into the first two years of the Trump administration.

"People are going to die if we don't start addressing climate change ASAP", Ocasio-Cortez tweeted Friday.

"Annual losses in some economic sectors are projected to reach hundreds of billions of dollars by the end of the century - more than the current gross domestic product (GDP) of many USA states", the report said.

On Wednesday, Trump tweeted, "Whatever happened to Global Warming?" as some Americans faced the coldest Thanksgiving in over a century.

"Adaptation and mitigation policies and programs that help individuals, communities, and states prepare for the risks of a changing climate reduce the number of injuries, illnesses and deaths from climate-related health outcomes", the report stated. However, several said the timing of its release, at 2 p.m. the day after Thanksgiving, appeared created to minimize its public impact. The Brookings Institution said: "The economic cost of climate change is high: an annual $12 billion increase in electricity bills due to added air conditioning; $66 billion to $106 billion worth of coastal property damage due to rising seas; and billions in lost wages for farmers and construction workers forced to take the day off or risk suffering from heat stroke or worse".

"I've seen it. I've read some of it". So, warming temperatures is just one response of the changing climate system, so it's just a better way of framing it.

"I had breakfast this morning too, and that doesn't mean we alleviated world hunger - and that's what that logic is like". Sea level rise will also cost an estimated $118 billion, and damages to infrastructure could total $32 billion, the report says.

But the Trump administration is trying to increase fossil fuel use, so it's working towards exactly that high emissions scenario future.
