In particular, at 3.2 °C (5.8 °F), 15% of invertebrates (including 12% of pollinators), 11% of amphibians and 10% of flowering plants would be at a very high risk of extinction, while ~49% of insects, 44% of plants, and 26% of vertebrates would be at a high risk of extinction. (wikipedia.org)

According to IUCN, once a species has lost over half of its geographic range, it is classified as "endangered", which is considered equivalent to a >20% likelihood of extinction over the next 10-100 years. (wikipedia.org)
But if we extrapolate based on estimations of invertebrate extinctions not considered by the IUCN, the situation looks far worse. (sciencealert.com)
Based on "bold" extrapolations from a number of previous studies examining invertebrate declines, the researchers suggest between 7.5 to 13 percent of all the roughly 2 million known plant and animal species on Earth could have gone extinct since 1500 CE - an extinction toll orders of magnitude greater than what the IUCN recognizes.

The biological carbon cycle has a very fast circulation rate compared to the geological cycle. (lu.se)
