Scientists are seeing changes in the earth’s climate in “every region and across the whole climate system,” according to a new report released Monday from the United Nations’ Intergovernmental Panel on Climate Change (IPCC), and in many cases the changes are irreversible in the short term. According to the report, what is being observed by scientists is “unprecedented” and has set in motion changes that will be “irreversible over hundreds to thousands of years,” including rising sea levels. The IPCC says “strong and sustained” reductions in greenhouse gases including carbon dioxide would limit climate change and air quality would come quickly, noting “it could take 20-30 years to see global temperatures stabilize.”

Canada’s Environment Minister says that while a newly released report on climate change raises international implications, it also has relevant impacts within Canada. “The wide-ranging IPCC report has unquestionable international implications. But it also matters here at home. Canada is warming at nearly twice the global rate,” Mr. Wilkinson said in a statement. “Parts of Western and Northern Canada are warming at three times the global average. Scientists have made a clear link between climate change and more frequent and powerful weather events, including heat waves, wildfires, flooding and sea ice loss.” Mr. Wilkinson said he expects the report’s findings will influence talks at the United Nations Climate Change Conference of the Parties—COP26—in November.
