Since the 1980s, climate change has increasingly affected the habitats of European bumblebees, which are important pollinators for both wild plants and crops. These insects play a crucial role in maintaining biodiversity and food production. However, global biodiversity is declining rapidly due to various human-caused factors, such as overfishing, pollution, the spread of non-native species, and climate change. Although there is a growing body of research on how climate change affects wildlife, few studies have clearly linked observed declines in biodiversity to climate change or measured its impact compared to other factors. In a recent study published in the journal Nature Climate Change, researchers from Belgium focused on the impact of climate change on bumblebee habitats. They examined 47 bumblebee species and used over 800,000 georeferenced records of where these species have been observed. Using this data, they developed ecological niche models that predict the areas where each species can thrive based on environmental conditions. The researchers then compared two sets of climate data: one representing the actual climate from 1901 to 2019, and another that removed any long-term warming trends. By comparing these models, they were able to isolate the effect of climate change on bumblebee habitats. The findings show that climate change has already significantly altered the areas in Europe that are ecologically suitable for bumblebees. On average, there has been a 5% reduction in suitable habitat due to climate change, with some regions experiencing losses as high as 19%. These changes have become more pronounced since the 1980s, a period marked by faster global warming. Southern and central European regions have been hit hardest, while in the Alpine and Boreal regions, gains in suitable habitat at higher altitudes have somewhat balanced out the losses at lower altitudes and latitudes. The researchers emphasize that as global temperatures continue to rise, the impact on bumblebee habitats is likely to worsen. They argue that both reducing greenhouse gas emissions and protecting and managing natural habitats are essential to preserving pollinator species and the ecosystem services they provide. Without such measures, the distribution of insect species, including bumblebees, could continue to shift, with potentially serious consequences for biodiversity and food production.
