Researchers see future trends
Heat records fall from Russia to Canada
In the small Canadian town of Lytton, an 83-year-old temperature record was recently exceeded by almost five degrees Celsius, and worldwide temperature records are falling, especially in the northern hemisphere. The consequences for humans and nature are devastating and an end to the development hardly seems in sight.
Last month was the hottest June ever in North America, according to the EU Earth observation program Copernicus. Temperatures have been recorded there since 1979. Parts of the USA and Canada were hit by a massive heat wave in the past few weeks, which led to numerous forest fires, but also to a high number of heat deaths. “These heat waves do not take place in a vacuum. They take place in a global, warming climate environment, which makes their occurrence more likely,” said climate researcher Julien Nicolas of Copernicus.
In the Canadian province of British Columbia, a new daily temperature record was recorded for three days in a row in June. According to Copernicus, the temperature in the region in June was 1.2 degrees above the average for the years 1991 to 2020. For Europe, it was the second warmest June since records began and, together with June 2018, the fourth warmest worldwide. Only in 2016, 2019 and 2020 were higher average temperatures measured. On the other hand, it was colder than the average from 1991 to 2020 in Antarctica.
It was unusually warm, especially in the western United States and Canada, as well as in Finland, Norway and western Russia. In the Finnish capital Helsinki, where records date back to 1844, the June average temperature has never been higher than this year for nearly 180 years. According to the Meteorological Institute of Finland, last 33.5 degrees Celsius were recorded in northern Finnish Lapland, which was the highest measured temperature in this region for more than 100 years. Russia’s capital Moscow recorded the warmest June day ever recorded.
Heat waves more frequent, more intense and longer
As the Meteorological Institute of Norway announced on Twitter yesterday, 34.3 degrees Celsius were measured on Monday afternoon in the municipality of Porsanger in the northernmost Norwegian province of Troms and Finnmark – a record for the province. A heat wave has also been registered in nine of the eleven Norwegian provinces so far this year. This is defined in Norway when the maximum temperature averages at least 28 degrees on three consecutive days.
“The heat waves that we saw in North America, western Russia and northern Siberia last month are just the latest examples of a trend that is likely to continue into the future and is related to the warming of our global climate,” said Nicolas. The heat waves occur more frequently, are more intense and last longer than in the past.
The EU’s climate change service produces monthly reports on air temperature, sea ice and the water cycle. It is based on data from satellites, ships, aircraft and weather stations around the globe as well as model calculations.
