The carbon concentrations in the atmosphere finally pass 400-part-per-million, which is higher than they have been for at least 800,000 years. This is not a surprise for human being, but it matters for the rest species living on the same planet earth. We believe that we can survive 4-5 degrees warmer on average, While many species can’t. That is really we should be worried and concerned.
We had destructed the habitat of plants and animals that share with the same planet as us, as we crowded out them. A new study in Nature Climate Change, tells us: they will run out of habitable space, and many of them will die.
The Intergovernmental Panel on Climate Change (IPCC) has estimated that 20% to 30% of species would be at increasingly high risk of extinction if global temperatures rise more than 2˚C to 3˚C above preindustrial levels.
In the Nature Climate Change paper, they found that almost two-thirds of common plants and half of animals could lose more than half their climatic range by 2080 if global warming continues unchecked, with temperatures increasing 4˚C above preindustrial levels by the end of the century. Generally the species near the equator will suffer most, but biodiversity will suffer across the whole planet. But the good news is that a much hotter future isn’t a certainty.
