  • Limiting warming to 1.5 degree C would save majority of global species from climate change
    on May 17, 2018 at 6:36 pm

    New research finds that limiting global warming to 1.5 degrees C would save the majority of the world's plant and animal species from climate change. Species across the globe would benefit -- particularly those in Southern Africa, the Amazon, Europe and Australia. Examples of animals to benefit include the critically endangered black rhinoceros. Reducing the risk to insects is important because they are vital for 'ecosystem services' such as pollinating crops and being part of the food chain. […]
