As #COP30 gets underway in Belém, Brazil — here's a stark reminder via @nature.org that the amount of CO2 in the atmosphere has never been seen in human history (Homo sapiens likely first entered the picture around 300,000 years ago) #climatechange

Today Canada is divided between two groups: the people who are nervously awaiting the contents of #Budget2025 and the people who are enjoying an average Tuesday.

A new report from The Lancet shows that about 1,400 deaths in Canada were associated with wildfire smoke each year from between 2020 to 2024. Climate change is supercharging wildfires in Canada, making them bigger and more uncontrollable. toronto.citynews.ca/2025/10/28/1...

This quote from Jamaican PM Andrew Holness in the Associated Press: "There is no infrastructure in the region that can withstand a Category 5."

Well. That’s great.

Despite an abundance of water, Quebec is vulnerable to drought due to climate change. New research finds that if a 2021-style drought re-ocurred combined with a 3 °C rise in global temps, "low water levels could persist for a month longer" in the hardest-hit areas of the province.

UK food inflation is being driven by climate change-induced extreme weather, driving up price of butter, milk, beef, chocolate & coffee The price rises in those staples is contributing 40% of overall food inflation Climate change is hitting peoples' pockets, right now www.ft.com/content/ced8...

A bit of positive news for your friday — my colleague @enveco.bsky.social explains how Canada's electricity sector flipped the switch on emissions. @climateinstitute.bsky.social #ClimateChange #Emissions #NetZero

NEW An EPA report found that PFNA, a chemical in the drinking water of some 26M people, interferes with development and likely causes liver problems & male reproductive harms. The report was done in April, scientists told me. But the agency hasn't released it www.propublica.org/article/epa-...

Are "decarbonized barrels" of oil possible? According to @pembina.org, if a one-million-barrel-per-day pipeline is built in Canada, oil sands emissions alone could reach as high as 89 (Mt) CO2e annually by 2035. www.pembina.org//pub/not-so-...

What are your tricks to stay cool in a heatwave? What helps me: - cold showers, or running cold water over my wrists for 30 sec - if I can't get to a/c, I find anywhere with shade and a fan or a breeze - I don't push myself with physical activity. Slow & steady and lots of breaks

Today could be the hottest June 23 ever recorded in Montreal! Temperatures are forecast to reach 10 C above average, according to CBC's Climate Dashboard by @naelshiab.bsky.social newsinteractives.cbc.ca/features/202...

It's going to be VERY hot and humid next week in Eastern Canada 🔥 Extreme heat made worse by climate change is a deadly threat. Don't forget that there could be a delay between temps dropping outside at night and the real temperature indoors — especially in older buildings. Stay safe!

Years after CBC's Verity Stevenson invited me to work with her on this story, I still think about the asylum seeker at the heart of this case. A kindhearted man who came to Quebec to earn a living and ended up with the top of his hand sliced off. www.cbc.ca/news/3-guilt...
