Heat & Temperature

ACORN is eyeing air conditioning for low-income residents in Ottawa—but has been concerned that more efficient heat pumps are priced out of reach for now.

Fossil fuel-driven climate change made the extreme fire weather conditions behind this summer’s ferocious wildfires in Ontario and the Northwest Territories roughly twice as likely to occur, concludes new research from Imperial College London’s World Weather Attribution (WWA) initiative. 

As devastating wildfires continue to burn across swaths of Canada, the United States, and Europe, oil major Shell posted $9.8 billion in second quarter profits, more than double its earnings from this time last year.

Oil companies face new legal challenges, such as a recent suit for wrongful death, and older cases that are creeping toward trial, Grist reports.

A series of four brutal heat waves so far this summer has brought down water levels in two of Europe’s mightiest rivers, impeding coal and diesel resupply in Germany, shutting down nuclear reactors in Hungary and Romania, and prompting Hungarian Prime Minister Péter Magyar to declare an imminent crisis amid...

Record heat, wildfire threats, and an unprecedented stage modification highlighted the growing challenge global warming poses to endurance sports.

Hot on the heels of a new round of 50% tariffs on a wide range of Canadian imports, scheduled to take effect Aug. 19, Donald Trump has instructed his administration to look into a separate punitive measure in response to wildfire smoke crossing the border.

The expense involved in retrofitting Toronto’s considerable stock of aging high-rise apartments is one longstanding obstacle to getting a maximum heat bylaw on the books, writes the Toronto Star. Tenant fears of steep rent increases when landlords pass on the costs are another obstacle.

Measures of what researchers call “excess mortality”—the difference between the normally expected number of deaths and the actual number—spiked in late June, when parts of Europe experienced record temperatures.

New AI-driven forecasts can tell you when dangerous weather is coming, Prof. Catherine Nakalembe writes for Yale Climate Connections. However, the barrier to saving lives is rarely data accuracy, but the absence of the policy infrastructure required to act on it.

The region has added dozens of turbines off the East Coast since last summer. They and other clean energy sources cut the need for oil power in a summer heat wave.

The ocean absorbs 90% of the excess heat from global warming. It doesn't all stay there.

The record-shattering wave of heat and humidity blanketing parts of Quebec, Ontario, and the United States, affecting Canada Day celebrations in the nation’s capital and World Cup matches in both countries, “would have been virtually impossible in a climate without fossil fuel use,” Oxford University-based World Weather Attribution (WWA) has...

Extreme heat kills more people each year than gun violence, says Rob Thornton, president and CEO of the International District Energy Association. That’s one of the reasons district energy “is really surging right now.”

The statistical and public health work of tallying heat-related deaths could take weeks or months. But it's already apparent that the toll exacted by the intense, unrelenting extreme temperatures was terrible in France, the first country hit from mid-June, particularly among older people who died at home.
