Introduction
Europe is experiencing an unprecedented heatwave, with record temperatures being broken in several countries. The cause of this phenomenon is a strong area of high pressure, known as a “heat dome”, which has been driving extreme temperatures.
What is a Heat Dome?
A heat dome is a large and persistent area of high pressure in the upper atmosphere that allows heat to accumulate over a region for several days. It limits the rise of air, preventing the hot air from rising and forming clouds. As the hot air descends within the system, it is compressed and heats up even more, raising temperatures constantly.
Impact of Climate Change
Although the heat dome phenomenon is natural, scientists say that climate change is increasing its frequency and intensity. The world has turned up the thermostat, explains Liz Bentley, executive director of the Royal Meteorological Society and professor of meteorology at the University of Reading. “Climate change definitely impacts the fact that heatwaves are more frequent, more intense, and also more persistent. They last much longer than they used to.”
Current Situation in Europe
In the UK, the Met Office says that temperatures may reach 40°C in parts of Wales and central and southern England. Several events of the Climate Action Week in London were canceled due to the extreme conditions. France, which is being particularly affected, had 58 administrative departments under red heat alert on Wednesday, and Paris recorded 40°C.
Consequences of the Heat Dome
Tens of thousands of homes in western France were left without electricity due to the lack of cooling capacity of nuclear power plants. At least three nuclear power plants shut down reactors because the river water used for cooling was too hot. Production fell by 4.1 gigawatts (GW) – 7% of total demand.
Other Affected Countries
Other European countries are under extreme heat alert, including Spain, Portugal, Switzerland, Luxembourg, and Germany, which have forecast temperatures between 37°C and 45°C this week.
Conclusion
The heat dome affecting Europe is a clear example of the impact of climate change on our planet. It is essential that we take measures to reduce greenhouse gas emissions and mitigate the effects of climate change.
