The Paris Agreement aimed to limit global warming to 2℃ with a major emphasis of maintaining the climate to say as low as possible. Most research neglected to study the effects climate warming would have on insects which are important to maintain a healthy ecosystem.
If warming is limited to 1.5℃ then more species have a greater chance of adapting to the change, more so when compared to the set 2℃. Species around the world would benefit, but particularly those in Southern Africa, the Amazon, Europe, and Australia.
