NASA Rising Seas: The State of the Greenland Ice Sheet (2015)

Seas around the world have risen an average of nearly 3 inches since 1992, with some locations rising more than 9 inches due to natural variation, according to the latest satellite measurements from NASA and its partners. An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of…

Fossil Fuel Emissions could Eliminate the Antarctic Ice sheet entirely, causing about 58 m Sea Level Rise

A new open access study in Science Advances concludes that a warming beyond the 2°C target would potentially lead to rates of sea-level rise dominated by ice loss from Antarctica, and continued CO2 emissions from fossil sources could cause additional tens of meters of sea level rise, over the next millennia and eventually ultimately eliminate the…

Sea level rise of the past 23 years explained

Oceanographer Josh Willis from NASA’s Jet Propulsion Laboratory narrates this video about the causes of sea level rise and how sea level has changed over the last two decades as observed by the Jason series of satellite missions. Source Related The troubling reasons why NASA is so focused on studying sea level rise The Science…

Doubling times of 10, 20 or 40 years yield sea level rise of several meters

According to a new study, sea level rise of several meters might happen faster then previously thought. Based on data from past climate changes, when sea level rose to +5–9 m, including the occurrence of extreme storms – during a time when temperatures were less than 1 ◦C warmer than today, experts warn of similar…

Eric Rignot: Observations suggest that ice sheets and glaciers can change faster, sooner and in a stronger way than anticipated

Eric Rignot Professor of Earth system science at the University of California, Irvine, and scientist at NASA’s Jet Propulsion Laboratory was interviewed on sea level rise and projections. Ice sheets and glaciers can change faster, sooner and in a stronger way than anticipated Machens: As an ice sheet expert, how do you see the sea-level projections…

We need to really begin the phase out of CO2 emissions

Think of climate change as a cancer. Your doctor told you that he spotted what appears to be likely a melanoma skin cancer, but he is not 100% sure. Do you wait till the signs become more apparent? The cancer might spread in your body, by that diminishing the chance for survival, or do you ask the…

ScienceCasts: No Turning Back – West Antarctic Glaciers in Irreversible Decline

A 2014 study study led by NASA researchers shows that half-a-dozen key glaciers in the West Antarctic Ice Sheet are in irreversible decline. The melting of these sprawling icy giants will affect global sea levels in the centuries ahead. Read more http://science.nasa.gov/science-news/science-at-nasa/2014/12may_noturningback/

NASA experts explain ice melt in Antarctica

NASA hosted a media teleconference to discuss new research results on the stability of the West Antarctic Ice Sheet and its potential contribution to future sea level rise. The briefing participants are: — Eric Rignot, professor of Earth system science at the University of California, Irvine, and glaciologist at NASA’s Jet Propulsion Laboratory in Pasadena,…
