"National Climate Assessment, to be launched at White House on Tuesday, says effects of climate change are now being felt."
"Climate change has moved from distant threat to present-day danger and no American will be left unscathed, according to a landmark report due to be unveiled on Tuesday.
The National Climate Assessment, a 1,300-page report compiled by 300 leading scientists and experts, is meant to be the definitive account of the effects of climate change on the US. It will be formally released at a White House event and is expected to drive the remaining two years of Barack Obama's environmental agenda.
The findings are expected to guide Obama as he rolls out the next and most ambitious phase of his climate change plan in June – a proposal to cut emissions from the current generation of power plants, America's largest single source of carbon pollution.
The White House is believed to be organising a number of events over the coming week to give the report greater exposure."
