Canada Hit With Extremes

Weather patterns in Canada have brought both record-breaking heat and cold.

Recently, Western Canada has experienced significant June snowfall and record cold while Eastern Canada has faced an early taste of summer. Last Wednesday alone, Alberta set 13 new record low temperatures, with Hendrickson Creek dropping to -2.7C (27.1F). Simultaneously, heat records were slain in Ontario, Quebec, and the Atlantic provinces.

Ken Dosanjh, a meteorologist at Environment and Climate Change Canada (ECCC), noted that while fluctuations in atmospheric circulation are normal, the recent extremes are unusual. Kerri Lang, a warning preparedness meteorologist for ECCC, echoed Dosanjh, saying the current situation is distinguished by the intensity of these extremes, which are breaking all-time records.

A key factor in these weather patterns is the jet stream, which separates colder air to the north from warmer air to the south.

Typically, it flows west to east in a relatively straight line. However, scientists, as reported by mainstream outlets such as cbc.ca even, say the jet stream has become less stable and more wavy, contributing to the recent weather extremes.

As the jet stream dips across Canada, it is causing heat in the east (below the jet stream) and cold in the west (above it).

Some researchers suggest that prolonged periods of low solar activity could be responsible for weakening the jet stream.

During the Maunder Minimum, a notable period of diminished solar activity, Europe and North America experienced some of the coldest winters in documented history.

A weakened jet stream played a huge part in this, as it shifted from its typical zonal flow (west-east) to a more meridional flow (north-south). This change allowed Arctic air masses to penetrate much further south than usual, causing extended cold spells and significant cooling across the affected regions. Conversely, on the flip side, extreme heat was also a theme, such as in Siberia.

There are many studies underscoring the influence of solar activity on the jet stream.

Swiss Glacier Recovery

Swiss glaciers have been enjoyed a season of heavy snowfall, drastically improving their condition, so says Matthias Huss, head of the Swiss Glaciological Survey Network (GLAMOS).

In a recent post on X, Huss noted that at the summer solstice, the state of Swiss glaciers is better than it has been in many years. Earlier in June, Huss described the weather this year as a "blessing" for Swiss glaciers.
