ouyIvWG3Fd- NWS Weather Prediction Center June 23, 2021Īs an area of high pressure began to close in on Friday 25 June, the first temperature record – a record-high minimum daily temperature in Seattle – was broken. All-time June monthly records could also be broken in some locations in the Pacific Northwest. Over 80 sites are forecast to break daily high temperature records starting this weekend. ⚠️Record-Breaking and Dangerous Heatwave coming to the West.
In this article, Carbon Brief summarises how the extreme heat and the role of climate change has been covered by the media. However, US president Joe Biden and Canadian prime minister Justin Trudeau have joined many climate scientists and media reports in linking the extreme temperatures to climate change. The heatwave is driven by an area of high atmospheric pressure sitting over the North American continent, which many media outlets are calling a “ heat dome”. Nevertheless, hospitals are filling up with patients with “ heat-related illnesses” and the death toll has begun to rise. The heat has driven many cities to a standstill, forcing schools, Covid-19 vaccination centres and restaurants to close, as well as prompting governments to relax social-distancing rules to allow people without air conditioning to shelter in emergency cooling centres. Similarly, Seattle and Portland in the US have seen three consecutive days of record-breaking temperatures. Before this heatwave, the highest recorded temperature in the region was 45C. In Lytton, a small village in Canada, record-breaking temperatures of 46.1C (115F), 47.9C (118F) and 49.6C (121.3F) were recorded on three consecutive days. "The Northwest Heat Wave Is 'Unprecedented.' Here's What's Pushing It Into Uncharted Territory.Less than two weeks after record-breaking temperatures forced California into a state of emergency, a severe heatwave has swept over northwestern US and Canada, shattering records across the region.

These are extremely dangerous numbers, especially in a region not used to heat like this, where many people do not have air conditioning.īy Monday, some - if not all - of the all-time record highs seen below are forecast to break, with many more cities not listed here expected to achieve the same feat."
Canada is expected to register the nation's all-time highest temperature before the event is done. Portland, Oregon, has already broken its all-time record hottest temperature at 108 degrees on Saturday and the peak of the heat wave has not even been reached yet. By one measure it is more rare than a once in a 1,000 year event - which means that if you could live in this particular spot for 1,000 years, you'd likely only experience a heat dome like this once, if ever. Pacific Northwest and British Columbia, Canada, is of an intensity never recorded by modern humans.
