A comprehensive review by 13 US federal agencies concludes that evidence of global warming is stronger than ever and that more than 90% of it has been caused by humans.

| The 477-page report said it’s ‘extremely likely’ that global warming is manmade. |
The conclusion contradicts a favorite talking point of senior members of the Trump administration.
A 477-page report released on Friday said it was “extremely likely” – meaning with 95 to 100% certainty – that global warming is manmade, mostly from carbon dioxide through the burning of coal, oil and natural gas.
The energy secretary, Rick Perry, and Environmental Protection Agency chief, Scott Pruitt, have said carbon dioxide is not the primary contributor to global warming.
Since 1900, the report says Earth has warmed by 1C and seas have risen by 8in. Heatwaves, downpours and wildfires have become more frequent.
