evidence: At 1.5 degrees of warming, the IPCC predicts that higher ocean temperatures would drive some marine species toward higher latitudes where they could potentially survive but which could then cause major disruptions in existing ecosystems. And, of course, not all species can simply move away. For instance, between 70 and 90 percent of tropical coral reefs would likely die, imperiling the $11 trillion in ecosystem services they currently provide annually in the form of fisheries, tourism, coastal protection, and more. Climate projections also have both heavy rains and droughts growing in frequency and intensity, along with increasing poverty levels. [...] We must also consider the unprecedented nature of the climate crisis, which means there is still a lot that scientists just don’t know. Spikes in land and sea temperatures in 2023 greatly exceeded predictions by climate models, revealing the gaps that remain in our overall understanding of how rising temperatures could affect the complicated systems and feedback loops that govern life as we know it on this planet.
