Climate change is real, man-made, and getting worse, Trump administration reports

Climate change is real. It’s caused by greenhouse-gas pollution released by human industrial activity. Its consequences can already be felt across every region and coastline of the United States—and, unless we stop emitting greenhouse gases soon, those consequences will almost certainly get worse.


Those are the headline findings of the Climate Science Special Report, a sweeping and more than 800-page examination of the evidence. The report was published Friday by four agencies of the U.S. government and academics from across the country.

Their conclusions form the first volume of the new National Climate Assessment, a report on the science and impacts of global warming that Congress requires agencies to complete every four years. A draft version of the second volume, on the human impacts of climate change, was also released Friday.

“This is the most comprehensive assessment of climate science currently available in the world, and it reaffirms what we’ve already known,” said Robert Kopp, one of the lead authors of the report and a professor of climate science at Rutgers University. “If we want to do something like stay under 2 degrees Celsius of warming, the window to do that is closing in the next couple decades.”

The two-degree limit is a rough target used by the United Nations to signal the point where dangerous climate change could begin. The report finds that the world can only continue to emit carbon for roughly another 23 years at current levels before it will have a more than two-thirds chance of going over the limit.

The Climate Science Special Report comes at an auspicious time in the history of global warming and the United States. The report’s conclusions do not deviate wildly from the last 20 years of consensus in climate science. They do not shock anyone who follows the field. And they don’t break new ground: The authors have synthesized the best available papers; they have not conducted new research for this report.  

A new Trump administration report on climate change paints an apocalyptic portrait of global climate trends, saying the last three years have been the "warmest years on record for the globe" and that humans are almost certainly causing the climate to change.

The massive, 477-page National Climate Assessment says that it is  "extremely likely" that global warming has been caused by humans -- with 95 to 100 percent certainty -- mostly from carbon dioxide through the burning of coal, oil and natural gas.

"It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century," the report says. "Over the last century, there are no convincing alternative explanations supported by the extent of the observational evidence."

So this is just a repeat of some of their favourite waffle...!

'Keep repeating the lie...'... eh!?
