​The number of climate refugees could increase dramatically in future. Researchers of the Max Planck Institute for Chemistry and the Cyprus Institute in Nicosia have calculated that the Middle East and North Africa could become so hot that human habitability is compromised. The goal of limiting global warming to less than two degrees Celsius, agreed at the recent UN climate summit in Paris, will not be sufficient to prevent this scenario.

The simple fact of the matter, a fact that many invested in a destructive oil industry do not want to now face, is that a fire whose early-season extreme intensity was fueled by human-caused climate change is now doing what Canada would not.

News alert! Despite what you may have heard, the war in Afghanistan is still raging. Nearly 10,000 US troops remain, and since 2014 the Obama administration has carried out almost 2,000 airstrikes on whatever they damn well please in the country. No question the mounting Afghan death toll and the bombing of hospitals and civilian infrastructure ought to infuriate the few remaining antiwar activists out there; but the toll the Afghanistan war is having on the environment should also force nature lovers into the streets in protest.

Politicians are reluctant to mention the role of global warming in the destruction of Canada’s oil sands capital.

The Fort McMurray fire disaster brings out the eloquence in Canada’s politicians. They talk movingly – and I think sincerely – about the devastation wreaked on the inhabitants of the northern Alberta city.

They praise the generosity of those Canadians who help. They put partisanship on ice. In one memorable instance last week, Prime Minister Justin Trudeau crossed the Commons floor to hug Rona Ambrose, the teary-eyed interim Conservative leader.

With each day the bad news spreads. A gigantic wildfire now covering some 4,000 km² is spreading through northeastern Alberta and into Saskatchewan — devastating much of Fort McMurray, the city in the heartland of the tar sands. Some 90,000 residents have been displaced and thousands of homes, many local industries and businesses, destroyed.

What's turning northern forests into tinder? Biggest reason is climate change, but that’s not all

A sudden shift in the wind at a critical time of day was all it took to send a wildfire out of control through Fort McMurray, forcing more than 80,000 people out of their homes in what has become the biggest natural disaster in Canadian history.

Earlier this week, Darby Allen, the regional fire chief for the area, minced no words when he was asked what might happen now that more than 1,600 homes have been destroyed.

Human activity has transformed the Earth, accelerating climate change in just a few decades. Author Ian Angus talks to Socialist Review about facing up to the new reality.
