专访丨热浪提前来袭 气候警钟再响——访欧盟气候监测机构科学家尼古拉斯

Core Insights - The Copernicus Climate Change Service reported that June 2023 was the third hottest June globally since records began in 1940, with Western Europe experiencing the hottest June on record [1] - The increasing frequency and intensity of heatwaves in Europe are closely linked to global warming, highlighting the urgency of the climate crisis [1] Group 1: Climate Trends - Western and Southern Europe experienced two significant heatwaves in late June, with the timing of these events shifting from July and August to June, indicating a direct impact of climate change [1] - Record high sea surface temperatures in the Western Mediterranean have intensified heatwaves, leading to "tropical nights" where nighttime temperatures do not drop below 20 degrees Celsius, posing serious health risks [1] Group 2: Ocean and Polar Conditions - The Mediterranean region is becoming a climate change "hotspot," with its warming rate significantly exceeding the global average, as oceans absorb about 90% of heat related to greenhouse gas emissions [1] - The Arctic is warming at a rate much faster than the global average, which may alter jet stream patterns and increase the frequency of extreme weather events [1] Group 3: Ice Coverage - In June, Arctic sea ice extent was 6% below the average, marking the second lowest June extent in 47 years of satellite records, while Antarctic sea ice extent was 9% below average, the third lowest on record for June [2] Group 4: Future Projections and Recommendations - Eastern and Southeastern Europe may face higher risks of heat and drought in the coming months, with heatwaves becoming a new norm for European summers due to ongoing climate change [2] - Addressing climate change should focus on two key areas: accelerating mitigation measures to reduce greenhouse gas emissions and enhancing resilience across various sectors to cope with extreme weather and long-term warming trends [2]
