CNA Explains: Europe is baking under a heat dome. What is it?
Is a heat dome linked to climate change? Climate scientists suspect that they could be linked, said Prof Koh, noting that Europe has experienced more frequent heat domes in the past decade than in previous decades. Heat domes are natural occurrences which happen from time to time, he said, adding that the longer a high-pressure system stays, the more intense the heat dome will be. “At its root, the phenomenon is not caused by climate change,” he added. However, Prof Koh noted that as global warming causes the Arctic to heat up more quickly than the rest of the world, the jet stream in the northern hemisphere is expected to weaken. “This would make it easier for heat domes to form,” he said. “Climate scientists suspect that this is linked to global warming.” Scientists say the current heatwave is making extreme events more likely and severe. A recent scientific study found that the current heatwave in Europe was “significantly exacerbated by human-induced climate change”. Without global warming, temperatures would have been 2°C to 4°C lower. …
