In the midst of Climate Week and National Clean Energy Week, a major climate science report is coming out. On Wednesday, September 25 at 5am ET, the Intergovernmental Panel on Climate Change (IPCC) will release the Special Report on the Ocean and Cryosphere in a Changing Climate. More than 100 leading scientists from 36+ countries prepared the report, citing nearly 7,000 research publications. Here’s what to look for:
In recent decades, more than 90% of the excess heat and 25% of human-caused CO2 emissions have gone into the ocean. This has limited the severity of global warming on land, but with major consequences that affect humans and ecosystems alike. The warming waters are devastating coral reefs, and leading to oxygen depletion with dead zones that inhibit marine life. Dissolved CO2 also leads to an increase in ocean acidity, which has surged by 30% over the past 250 years—with significant impacts on many species. And rising sea levels are already an urgent concern, flooding coastal communities around the world. Drastically cutting our greenhouse gas emissions—as emphasized in last year’s IPCC report—would lessen these impacts.

Sea level rise from human-caused climate change is increasing the frequency of coastal flooding. The rapid increase in the last 10 years is allowing annual king tides to reach farther inland.
