5 Things to Know Today: Oil Surges, Tariffs Land Tomorrow, Your Gas Tax Break Survives

  Monday, September 7, 2026 — Labour Day | Canadian Money Brief Markets are closed for the holiday, but the week ahead is loaded. Here are five things worth knowing before you head back to your desk tomorrow. 1. Oil Hits a Five-Week High as the Iran Conflict Escalates Crude climbed to $92.06 US/barrel on Saturday — up 17.75% over the past month and nearly 48% year over year — after Iran and the United States exchanged missile strikes this week. Israel's defence minister has threatened "crippling" attacks on Iran's energy infrastructure, the EU has formally joined the US-led sanctions campaign, and US Vice President JD Vance said Washington won't hold peace talks until Iran stops targeting ships in the Strait of Hormuz. What it means for you: Even with the federal gas tax break extended (see #4), pump prices track the price of crude itself. If your tank's getting low, filling up early this week may beat whatever the Strait of Hormuz situation does to prices by...

Unprecedented Heat Wave Hits Antarctica: Temperatures Soar 50°F Above Normal

 

In an alarming turn of events, Antarctica is experiencing an extraordinary heat wave, with temperatures soaring up to 50°F above normal. This unprecedented phenomenon is unfolding during what should be the coldest period in Earth’s coldest region, raising significant concerns among scientists about the future health of the Antarctic continent and its global implications.

Since mid-July, parts of East Antarctica have seen temperatures that typically range between -58°F and -76°F rise to between -13°F and -22°F. While these temperatures are still below freezing, the deviation from the norm is staggering. This summer-like heat in the dead of winter is a stark reminder of the accelerating impacts of climate change.

The implications of such a heat wave are profound. Antarctica holds the majority of the planet’s ice, and significant melting could lead to catastrophic sea level rises. Even smaller ice features, like the so-called Doomsday Glacier, could raise sea levels by up to 10 feet if they were to melt. This would have devastating effects on coastal communities worldwide.

Scientists are particularly concerned about the potential for more frequent heat waves in Antarctica’s future winters. Such events could leave the continent less fortified for its summer season, making it more vulnerable to further melting during subsequent heat waves. Additionally, increased Antarctic melting could disrupt global oceanic circulations, which play a crucial role in maintaining the planet’s climate balance.

David Mikolajczyk, a research meteorologist with the Antarctic Meteorological Research and Data Center at the University of Wisconsin-Madison, emphasized the need for further study to understand the full impact of this heat wave. “I’m sure more impacts will emerge with time as we understand this heat wave better, but at the moment, it’s just a case of astonishment really, what we’re seeing,” he said.

This extraordinary event serves as a stark reminder of the urgent need to address climate change and its far-reaching effects on our planet.
