Abstract：
OBJECTIVE: Delineation of the impact of elevated carbon dioxide and concomitant global warming on airborne allergens is performed.
RESULTS: European tree pollen trends in general showed earlier start and end dates and increased total pollen release, with some differences both in locale and among species. Earlier flowering was also seen with grasses and weeds. In the case of some boreal trees, flowering was delayed due to a pre-seasonal requirement for necessary accumulated chilling temperature to achieve bud-set. Anthropogenic climate change induced rise in temperature and CO2 levels has resulted in demonstrable increases in aeroallergens. This has been most dramatic in tree pollen annual load, but also seen with grasses and weeds. Collected data is greatest for the Northern Hemisphere, especially the European continent, with supporting data from North America and Australia.

摘要：
目的：对二氧化碳升高和伴随的全球变暖对空气过敏原的影响进行了概述。
结果：欧洲树木花粉趋势总体上显示出较早的开始和结束日期以及花粉总释放量增加，在地区和物种之间都有一些差异。早期开花也见于草和杂草。在一些北方树的情况下，由于季节前需要必要的累积冷却温度以实现芽的凝固，因此开花被推迟。人为的气候变化引起的温度和CO2水平升高导致了空气过敏原的明显增加。这在树木花粉年负荷中最为引人注目，但也可以看到草和杂草。北半球收集的数据最多，尤其是欧洲大陆,来自北美和澳大利亚的支持数据。
