Climate change has become a serious concern for many years. Not only does it harm the environment, but also the ecosystem. For example, some species across the globe is in the risk of extinction owing to many reasons and one of the serious reasons is climate change. Species, especially in the southern part of Africa, the Amazon and Australia are at the risk of extinction due to the climate change. Moreover, insects that play a crucial role in food chain and ecosystem are in danger. Therefore, some researchers of the University of East Anglia studied how could we reduce the impact.
For this, they studied almost 115,000 species that includes many insects, mammals, reptiles, amphibians, and plants. They measured the risk of extinction and danger to biodiversity by measuring a number of species that are prone to lose, owing to climate change, more than half of their range.
"Insects are particularly sensitive to climate change. At 2 degree c warming, 18 percent of the 31,000 insects we studied are projected to lose more than half their range.This is reduced to 6 per cent at 1.5 degree c. But even at 1.5 degree c, some species lose larger proportions of their range. The current global warming trajectory, if countries meet their international pledges to reduce CO2, is around 3 degree c. In this case, almost 50 per cent of insects would lose half their range.”

Therefore, insects will be an extinction or will lose their range and a significant amount of their ecosystem services will be reduced if the temperature is risen by 3 degree c. However, if the warming decreases to 1.5 degree c by the start of 2100, then we can see an increased number in species and their range, one of which is Black RhinoCeros that is currently in the list of extinction and endangered species. Therefore it is our responsibility to understand the warming and act accordingly.
