AGU 2015: Eric Rignot – Ice Sheet Systems and Sea Level Change

Scientific Discipline Cryosphere Speaker Eric Rignot (NASA Jet Propulsion Laboratory) Abstract Modern views of ice sheets provided by satellites, airborne surveys, in situ data and paleoclimate records while transformative of glaciology have not fundamentally changed concerns about ice sheet stability and collapse that emerged in the 1970’s. Motivated by the desire to learn more about…

Worldwide Extreme Floods (Sep-December 2015 – Japan/Brazil/India/UK/USA South Florida)

Footage of recent flooding in Japan, India, Brazil, UK (Northern England / Wales / Scotland / Cumbria), Florida United States. There have been more floods, i.e. in Portugal, Singapore, and other parts of the world, and it is projected to get worse with increased temperatures due to global warming. New York Times: A 2015 study…

Climate change could suffocate life on planet Earth

EurekAlert (Release): Falling oxygen levels caused by global warming could be a greater threat to the survival of life on planet Earth than flooding, according to researchers from the University of Leicester. A study led by Sergei Petrovskii, Professor in Applied Mathematics from the University of Leicester’s Department of Mathematics, has shown that an increase in…

Why 2°C Global Warming is Highly Dangerous

Recently, James Hansen the former director of NASA GISS published new study findings about future sea level rise, ice melt, and temperature changes, as well as the possible implications for future climate. Above video highlights a part of a talk Hansen held on December 1, 2015 at the Paris climate change conference (COP21). The take…

Research links abrupt paleoclimatic change to possible methane hydrate destabilization

Using a core sample from the Santa Barbara Basin, UCSB researchers decipher the history of paleoclimate change with surprising results By Julie Cohen (UCSB): Global climate change isn’t new — the phenomenon has been around for millions of years. But now, a core from the ocean floor in the Santa Barbara Basin provides a remarkable…

NASA State of Sea Level Rise Science 2015 – 30 feet of SLR possible by 2100

Excerpt from https://www.youtube.com/watch?v=vDdNxb2xVBU Members of NASA’s new interdisciplinary Sea Level Change Team discussed recent findings and new agency research efforts during a media teleconference Aug. 26, 2015, at 12:30 p.m. EDT. The panelists for this briefing were: — Michael Freilich, director of NASA’s Earth Science Division at the agency’s headquarters in Washington — Steve Nerem,…

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…

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…
