NASA: Greenland ice loss 2002-2016
The mass of the Greenland ice sheet has rapidly declined in the last several years due to surface melting and iceberg calving. Research based on observations from the NASA/German Aerospace Center’s twin Gravity Recovery and Climate Experiment (GRACE) satellites indicates that between 2002 and 2016, Greenland shed approximately 280 gigatons of ice per year, causing…
NASA: Antarctic Ice Loss 2002-2016
The mass of the Antarctic ice sheet has changed over the last several years. Research based on observations from NASA’s twin NASA/German Aerospace Center’s twin Gravity Recovery and Climate Experiment (GRACE) satellites indicates that between 2002 and 2016, Antarctica shed approximately 125 gigatons of ice per year, causing global sea level to rise by 0.35…
Watch how cities will get flooded with 10 feet sea level rise
Visualisation of sea level rise of 10 feet (3 meters), based on the risk zone map, provided by Climate Central. Current estimates about future sea level rise, consider up to 10 feet already locked in, due to the greenhouse gas emissions we have emitted so far. How fast this will happen is not certain yet.…
The Climate Spiral: Carbon budget, CO2 and Temperature since 1850
07/27/2016 – Global-mean temperatures are breaking one record after the other since instrumental observations began. Driven by burning of fossil fuels and deforestation, carbon dioxide concentrations have also soared to unprecedented levels. In fact, today’s CO2 concentrations are higher than they have ever been over the last 800 thousand years. Scientists from the Potsdam Institute…
NASA/NSIDC: 2016 Arctic sea ice wintertime extent hits another record low
2016 Arctic sea ice wintertime extent hits another record low By Maria-Jose Viñas, NASA’s Earth Science News Team Excerpt Arctic sea ice appears to have reached a record low wintertime maximum extent for the second year in a row, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA.…
NASA: Zachariæ Isstrøm Glacier Greenland entered accellerated retreat
NASA: Zachariæ Isstrøm has become the latest Greenland glacier to undergo rapid changes in a warming world. Research published November 2015 in Science found that Zachariæ Isstrøm broke loose from a stable position in 2012 and entered a phase of accelerated retreat. The consequences will be felt for decades to come. The reason? Zachariæ Isstrøm is…
Greenland Ice Mass Loss: Jan. 2004 – June 2014
GRACE consists of twin co-orbiting satellites that fly in a near polar orbit separated by a distance of 220 km. GRACE precisely measures the distance between the two spacecraft in order to make detailed measurements of the Earth’s gravitational field. Since its launch in 2002, GRACE has provided a continuous record of changes in the…
Climate scientist Piers Sellers on NASA’s satellite observations
The view of Earth from orbit was the focus of this What’s New in Aerospace? presentation televised on NASA Television from the Smithsonian National Air and Space Museum in Washington. The program featured Piers Sellers, a climate scientist and former NASA astronaut, taking viewers on a tour of our home planet as never seen before.…
Sudden ice loss acceleration at the Southern Antarctic Peninsula detected
ESA posted an update on Antarctic ice loss on 22 May 2015. Above animation shows how warm ocean water penetrates the glacier grounding line through basalt melt, threatening speed up of glaciers, discharged into the ocean. A recent acceleration in ice loss in a previously stable region of Antarctica has been detected by ESA’s ice mission. The…
Greenland’s Ice Layers Mapped in 3D
Peering into the thousands of frozen layers inside Greenland’s ice sheet is like looking back in time. Each layer provides a record of not only snowfall and melting events, but what the Earth’s climate was like at the dawn of civilization, or during the last ice age, or during an ancient period of warmth similar…
Sea Level Rise Projections until 2100, a nonlinear response?
Past sea level rise is not captured by models yet, in particular the response from ice sheets in Antarctica due to global warming. Projections therefore can often be regarded to potentially underestimate future sea level rise. For example, Overpeck et al. (2006), and Hansen (2007) suggest possibilities which could eventually lead to a nonlinear response…
Royal Society: An introduction to climate change in 60 seconds
Published on Dec 10, 2014: Climate science explained in 60 seconds by the Royal Society and the US National Academy of Sciences. During the last 200 years, human activities such as the burning of fossil fuels have increased concentrations of CO2 in the atmosphere by 40%. If unchecked, continuing emissions will warm up the planet…
Arctic Sea Ice, Summer 2014 (NASA animation)
An animation of daily Arctic sea ice extent in summer 2014, from March 21, 2014 to Sept. 17, 2014 – when the ice appeared to reach it’s minimum extent for the year. It’s the sixth lowest minimum sea ice extent in the satellite era. The data was provided by the Japan Aerospace Exploration Agency from…
