Trump rejects key conclusion of USA government climate report


US President Donald Trump on Monday, November 26, discarded projections that climate change will cause severe hardships to the American economy, thereby dumping findings by a report that Washington itself published last week.

The U.S. Global Change Research Program, mandated by Congress to coordinate research on climate change, supervised the report, which was released quietly on Black Friday.

It said warming-charged extremes "have already become more frequent, intense, widespread or of long duration".

The congressionally mandated report, written with the help of more than a dozen US government agencies and departments, said the effects of climate change would undermine human health, damage infrastructure, limit water availability, alter coastlines and increase costs in various industries.

The report says climate change will harm infrastructure and property and impede economic growth without regional planning and a substantial global effort to curb emissions.

"Trump is ignoring the alarm bells to protect our country from climate change, yet at the same time he is building sea walls in Scotland to protect his golf course from the rising sea, ' Brune said by email".

"Unlike President Trump, we trust the experts at NASA, the Department of Defense, and 10 other federal agencies who reviewed and endorsed this report", Keith Gaby, a senior communications director with the Environmental Defense Fund, said by email.

Last year, Trump announced he would withdraw the United States from the 2015 Paris Deal to combat climate change.

He told reporters on Monday that he had "read some of" Friday's report, which was compiled with help from U.S. government agencies and departments.

"Right now, we're at the cleanest we've ever been". "If we're clean, but every other place on earth is dirty, that's not so good", Trump said. USA output of crude oil is already the highest in the world, above Saudi Arabia and Russian Federation. Agriculture, tourism and fishing, industries that depend on natural resources and favourable climate conditions, would all be hit, it said.

The report warned of massive economic losses if carbon emissions continue to feed climate change unchecked.

The effects will spill into global trade, hitting import and export prices and United States businesses with overseas operations and supply chains, it added.
