Sea Level Rise: What It's Already Done and Where It's Headed

Papers mentioned in Video Temperature-driven global sea-level variability in the Common Eras Contribution of Antarctica to past and future sea-level rise Check out their COOL TOOL Forward projections indicate a very likely 21st century GSL rise of 52–131 cm under RCP 8.5 and 24–61 cm under RCP 2.6, values that provide greater consistency with process model-based projections preferred by AR5 than previous semiempirical projections
Sea Level 101 Global warming has raised global sea level about 8 inches since 1880, and the rate of rise is accelerating. Rising seas dramatically increase the odds of damaging floods from storm surges. A Climate Central analysis finds that sea level rise from warming has already doubled the odds of "century" or worse floods over widespread areas of the U.S., and the problem is growing by the decade.These increases threaten an enormous amount of damage. Across the country, nearly 5 million people live in 2.6 million homes at less than 4 feet above high tide — a level lower than the century flood line for most locations analyzed. And compounding this risk, scientists expect roughly 2 to 5 more feet of sea level rise this century — a lot depending upon how much more heat-trapping pollution humanity puts into the sky.
Climate Central’s Program on Sea Level Rise strives to provide accurate, clear and granular information about sea level rise and coastal flood hazards both locally and globally, today and tomorrow. Anchored in rigorous primary research, our work distinguishes itself by its user-friendly maps and tools, extensive datasets, and high-quality visual presentation. The program dedicates its efforts to helping citizens, communities, businesses, organizations, and governments at every level to understand the consequences of different carbon pathways and to navigate the shifting waters of our warming world.
Climate Change:How Skewed Are We...Really? (HSAWR?) A resource for people looking to find out about the science and the impacts of Climate Change and Anthropogenic Global Warming (AGW). This is accomplished by curating scientific, political and business videos, news reports, surveys and polls as well as creating original content. (CHECK OUT OUR HSAWR ORIGINAL VIDEOS)
The Pentagon," calls CLIMATE CHANGE an “urgent and growing threat to America's national security” and blames it for “increased natural disasters” that will require more American troops designated to combat bad weather.
