Updated 2022 estimates show that even at a global average increase of 1.5 °C (2.7 °F) over pre-industrial temperatures, only 0.2% of the world's coral reefs would still be able to withstand marine heatwaves, as opposed to 84% being able to do so now, with the figure dropping to 0% at 2 °C (3.6 °F) warming and beyond.

Data shows CO2 is also causing modern global warming − and an array of negative consequences − by slowing the escape of heat energy into space. CO2 can fertilize plants and also drive global ...
Several studies since the early 1990s [30] have shown that large-scale deforestation north of 50°N leads to overall net global cooling [31] while tropical deforestation produces substantial warming. Carbon-centric metrics are inadequate because biophysical mechanisms other than CO 2 impacts are important, especially the much higher albedo of ...
A 2018 study from the University of East Anglia team analyzed the impacts of 2 °C (3.6 °F) and 4.5 °C (8.1 °F) of warming on 80,000 plant and animal species in 35 of the world's biodiversity hotspots. It found that these areas could lose up to 25% and 50% of their species, respectively: they may or may not be able to survive outside of them.
Data from 2018 found that at 1.5 °C (2.7 °F), 2 °C (3.6 °F) and 3.2 °C (5.8 °F) of global warming, over half of climatically determined geographic range would be lost by 8%, 16%, and 44% of plant species. This corresponds to more than 20% likelihood of extinction over the next 10–100 years under the IUCN criteria. [41] [42]
Global warming may not just melt the polar icecaps and create a snowpocalypse previously only seen in 'The Day After Tomorrow.' Animals could 'shrivel' in size due to global warming, researchers ...
Changes to a diet less reliant on animal products such as plant-based diets are also effective. [10]: XXV With 21% of global methane emissions, cattle are a major driver of global warming. [225]: 6 When rainforests are cut and the land is converted for grazing, the impact is even higher.
