The NASA Sea Level Projection Tool allows users to visualize and download the sea level projection data from the IPCC 6th Assessment Report (AR6). The goal of this tool is to provide easy and improved access and visualization to the consensus projections found in the report.
12 cze 2024 · In the rosiest possible future, global average sea level will rise another 20 to 50 centimeters (8 to 20 inches) by the year 2100. Minchew says the low end of that range would require humanity to achieve negative greenhouse gas emissions —in other words, not only stopping new emissions but also removing some excess greenhouse gases already in ...
25 mar 2024 · These scientists project that global mean sea levels will rise almost 1 foot (0.28 meter) above 2000 levels by 2050—and above 3 feet (1 meter) by 2100. This is our “intermediate” scenario.
16 mar 2023 · Global mean sea level (GMSL) has risen at an accelerated rate in recent decades 1, 2, 3, 4, 5 due to oceanic thermal expansion, ice-mass loss and changes in terrestrial water storage 3. The...
25 paź 2022 · The high-end global mean sea-level rise is now projected to be up to 1.3-1.6 meters for strong warming in 2100. The collapse of major Antarctic ice shelves at the end of the century followed by increased discharge of ice may lead to a 9-10 meter catastrophic sea-level rise by 2300 under the same strong warming scenario.
Beyond 2100, sea level will continue to rise for centuries due to continuing deep ocean heat uptake and mass loss of the GIS and AIS and will remain elevated for thousands of years (high confidence). Under RCP8.5, estimates for 2100 are higher and the uncertainty range larger than in AR5.
Emerging science regarding Antarctic ice sheet stability suggests that, for high emission scenarios, a GMSL rise exceeding 8 feet (2.4 m) by 2100 is physically possible, although the probability of such an extreme outcome cannot currently be assessed.
