每日英語跟讀 Ep.K403: About heat waves - Heat Wave Killed Marine Wildlife en Masse
An early estimate points to a huge die-off along the Pacific Coast, and scientists say rivers farther inland are warming to levels that could be lethal for some kinds of salmon.
Dead mussels and clams coated rocks in the Pacific Northwest, their shells gaping open as if they’d been boiled. Sea stars were baked to death. Sockeye salmon swam sluggishly in an overheated Washington river, prompting wildlife officials to truck them to cooler areas.
The combination of extraordinary heat and drought that hit the Western United States and Canada over the past two weeks has killed hundreds of millions of marine animals and continues to threaten untold species in freshwater, according to a preliminary estimate and interviews with scientists.
Arctic heatwave could break records 北極熱浪恐破紀錄
Temperatures at the North Pole could be up to 20 degrees higher than average this Christmas Eve. Temperatures are forecast to peak on Christmas Eve around the North Pole - at near-freezing. Climate scientists say these unseasonably warm weather patterns in the Arctic region are directly linked to man-made climate change.
Temperatures throughout November and December were 5C higher than average. It follows a summer during which Arctic sea ice reached the second-lowest extent ever recorded by satellites.
Dr Friederike Otto, a senior researcher at Oxford’s Environmental Change Institute said that in pre-industrial times "a heatwave like this would have been extremely rare - we would expect it to occur about every 1,000 years".
Dr Otto added that scientists are "very confident" that the weather patterns were linked to anthropogenic climate change.
"We have used several different climate modelling approaches," she said. "And in all our methods, we find the same thing; we cannot model a heatwave like this without the anthropogenic signal."
「我們使用好幾個不同的氣候模型途徑，」她說。「然而在我們的方法中，我們發現相同之處：在缺少人為導因下，我們無法形塑出如此的熱浪。」Source article: https://features.ltn.com.tw/english/article/paper/1527294 ; https://news.ltn.com.tw/news/world/paper/1066371
