概括
欧洲农业面临越来越多的极端天气. 这项研究引入了欧洲极端事件气候指数 (E3CI) 用于泛欧洲风险评估,揭示了整个非洲大陆显著的变暖和干旱趋势.
科学领域:
- 农业气候学 农业气候学
- 极端天气事件分析
- 全欧洲环境风险评估
背景情况:
- 极端天气事件对欧洲农业构成越来越大的威胁.
- 此前没有对多种农业气候危害进行大陆范围的评估.
- 了解这些危险对粮食安全和农业可持续性至关重要.
研究的目的:
- 提供第一个泛欧洲,生长季节综合农业气候危害.
- 应用欧洲极端事件气候指数 (E3CI) 进行风险评估.
- 从1981年到2020年,量化危险频率和严重性的变化.
主要方法:
- 使用了欧洲极端事件气候指数 (E3CI),这是七种危险的综合指标.
- 分析了涵盖1981-2020年 (四月至十月) 期间的39个欧洲国家的数据.
- 使用十年对比和评估空间梯度 (西-东,北-南) 的量化变化与不确定性分析.
主要成果:
- 温暖 (6%至74%的生长季节) 和干旱频率 (8至13个案例/十年) 显著增加.
- 火灾严重程度急剧上升 (5至117),降雨和干旱严重程度增加.
- 观察到的空间对比:西欧/北欧地区的温暖,凉爽和风力加剧;东欧/南欧地区的干旱,降雨,冰和火灾加剧.
结论:

What is Climate?
20.4K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Adaptations that Reduce Water Loss
27.9K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Global Climate Change
28.7K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Threats to Biodiversity
26.5K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Responses to Heat and Cold Stress
14.7K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.
