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. 

• At 3.2℃ warming, climatically determined geographic range losses of  >50% are projected in the 49% of insects, 44% of plants, and 26% of  vertebrates. 
• At 2℃, that falls to 18% insects, 16% of plants, and 8% of vertebrates  and at 1.5℃ to 6% of insects, 8% of plants, and 4% of vertebrates. 
• At 1.5℃ as compared with 2℃, number of species projected to lose >50%  of their range are reduced by about 66% in insects and by about 50% in plants  and vertebrates.                    

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.
