It is said that the study of bumblebees has shown that mass extinctions, in which several species are extinct at the same time, are caused by climate change. The model developed by the team shows that temperature and precipitation can increase the risk of extinction of species that exceed acceptable limits.
A research team at the University of Ottawa announced that the number of bee populations in Europe and North America is dramatically decreasing. According to the research team, bumblebees are decreasing in places where an increase in temperature is observed. Depending on the location, the number of bees is declining by 30% by the first generation of humans, and this rate is consistent with mass extinction.
The findings were published in the scientific journal Science. In this study, the research team developed a simulation model for a scenario of climate chaos by collecting data on 66 species of bumblebees in North America and Europe over the past 115 years. According to this model, a comparison of how the number of populations at each location changes over time shows that climate change is already causing bees to decline, leading to more population losses as climate change accelerates over the next few years. Maintaining the diversity of bumblebees requires efforts to reduce climate change.
Bumblebees play a big role in pollination, such as tomatoes, spinach, and strawberries. The research team explains that the method developed this time can be used to measure the risk of extinction and to identify where species should be preserved. The research team said that the study suggests that the study provides a place for bumblebees to escape the heat such as plantings, shrubs, slopes, etc., thereby suppressing the impact of climate change on other organisms. It urged action to address environmental issues, suggesting that action to reduce the amount of water released will help. Related information can be found here .
