Study Projects Two Feet of Sea Level Rise by 2100
The research, published Monday in the Proceedings of the National Academies of Sciences, shows that global sea levels have risen roughly three millimeters (0.1 inches) per year in the past. However, that rate is not constant—it may jump to 10 millimeters per year by 2100.
One of the main drivers behind that acceleration is the melting ice sheets in Greenland and Antarctica.
Significantly, the projected sea level rise is a "conservative" estimate and may likely be higher, the researchers warn.
"There may be abrupt changes in the ice sheets," lead author Steve Nerem, a University of Colorado-Boulder professor of aerospace engineering sciences, told ThinkProgress. “That's why I think that this is a conservative estimate, because it doesn't consider what if the ice sheets really start to go."
The new research confirms computer-modeled projections from the UN's Intergovernmental Panel on Climate Change.
Nerem told InsideClimate News that the study is important because it relies completely on observational data.
"Some folks have not wanted to do anything about climate change because they don't trust the models. These findings support the modeled projections," he said.
Sea level rise is already causing major problems for coastal cities, from high tides to intense storm surges.
"Any flooding concerns that coastal communities have for 2100 may occur over the next few decades," Oregon State University coastal flooding expert Katy Serafin told the Associated Press.

No matter the time of year, there's always a point in each season when my skin decides to cause me issues. While these skin issues can vary, I find the most common issues to be dryness, acne and redness.

Now, correspondence obtained by the LA Times revealed just how deeply involved industry lobbyists and a controversial, industry-funded toxicologist were in drafting the federal agency's proposal to scrap its current, protective approach to regulating toxin exposure.
February 22 is the birthday of conservationist and beloved TV personality "Crocodile Hunter" Steve Irwin, who would have been 57 years old today.
Irwin's life was tragically cut short when the barb from a stingray went through his chest while he was filming in 2006, but his legacy of loving and protecting wildlife lives on, most recently in a Google Doodle today honoring his birthday.

That video showed the extrusion of a bubblegum-pink substance oozing into a coiled pile, something between Play-Doh, sausage and soft-serve strawberry ice cream. Branded "pink slime"—the name came from an email sent by a USDA microbiologist in 2002—this stuff was actually beef, destined for supermarkets and fast-food burgers.
'Kicking Ass for Her Generation': Applause for 16-Year-Old Greta Thunberg as EU Chief Pledges Billions to Curb Climate Threat

Sixteen-year-old climate action leader Greta Thunberg stood alongside European Commission President Jean-Claude Juncker Thursday in Brussels as he indicated—after weeks of climate strikes around the world inspired by the Swedish teenager—that the European Union has heard the demands of young people and pledged a quarter of $1 trillion budget over the next seven years to address the crisis of a rapidly heating planet.
In the financial period beginning in 2021, Juncker said, the EU will devote a quarter of its budget to solving the crisis.
