This morning, the United Nations-backed Intergovernmental Panel on Climate Change (IPCC) released its latest pentennial assessment of the world’s climate. Today’s release was a slim 21–page summary of more than a 1,000 pages of scientific evidence that will be released over the course of the year. The summary is intended for policy makers.
Changes in the atmosphere, the oceans and glaciers and ice caps now show unequivocally that the world is warming due to human activities.. the United Nations Intergovernmental Panel on Climate Change (IPCC) said in new report released today in Paris.
[UN] Secretary-General Ban Ki-moon pointed to the “scientific consensus regarding the quickening and threatening pace of human-induced climate change” and called for the global response “to move much more rapidly as well, and with more determination.”
And, here is Canada’s official reaction:
Environment Minister John Baird stated today that he and Canada's New Government accept the findings of the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report and called on Canadians to get ready for some tough decisions on reducing greenhouse gas emissions.
“The IPCC has presented compelling scientific proof that the world's climate has changed because of human action and industrial growth,” said Minister Baird. “This represents an important contribution to the body of scientific research on the topic. The evidence is in, and it is clear the time is now for concrete and realistic actions to deal with climate change and air pollution to improve the health of Canadians.”
Environment Canada also has its own IPCC page.
