NASA Study Shows Antarctica is Gaining Ice at About 82 Billion Tonnes per Year

Technical Rating: star
A new NASA paper shows that the Antarctic Ice Sheet has grown in mass by about 82 billion metric tonnes of ice per year (Gt/yr) between 2003 and 2008. This article summarizes reviews by Jim Steele and Steve McIntyre. The ice gain estimate is based on altimeter satellite measurements and new Glacial Isostatic Adjustment (GIA)estimates. The IPCC AR5 reported that the ice sheet has been loosing mass at about 147 Gt/yr, but this was based on obsolete GIA estimates. GIA estimates impact the altimeter ice mass estimates by less than 17% of the impact on the gravity ice mass estimates.



Climate Alarmists are Rescued from Antarctic Summer Sea Ice

Technical Rating: star
A collection of climate alarmist tourists and scientists have been rescued from their boat, trapped by record high Antarctic summer sea ice. The climate scientists aboard the Russian research vessel, the Akademik Shokalskiy, expected to find evidence of melting sea ice, but instead encountered record high Antarctic sea ice. The Antarctic 2013 year-average sea ice area is the highest ever recorded during the satellite era which began in 1979 and the present sea ice area is near the record high. Global sea ice area at year-end 2013 is the highest ever recorded for the date and the global 2013 year-average sea ice area is the highest since 1996.



Industrial Soot Linked to the Abrupt Retreat of 19th Century Glaciers

Technical Rating: star
A NASA-led team of scientists has uncovered strong evidence that soot from a rapidly industrializing Europe caused the abrupt retreat of mountain glaciers in the European Alps that began in the 1860s, a period often thought of as the end of the Little Ice Age. Black carbon is the strongest sunlight-absorbing atmospheric particle. When these particles settle on the snow blanketing glaciers, they darken the snow surface, speeding its melting and exposing the underlying glacier ice to sunlight and warmer spring and summer air earlier in the year.



The Melting North? No Increase in the Greenhouse Effect

Technical Rating: star star
The Economist magazine article "The Melting North" claimed that carbon dioxide (CO2) emissions are causing Arctic warming. We show that the greenhouse effect has not increased in the Arctic since 1979, so CO2 emissions cannot be the cause of the warming.



Global warming and Glacier Melt-Down Debate

Technical Rating: star
FoS scientific advisory board member Dr. Madhav Khandekar writes that Himalayan glaciers are not retreating any faster than glaciers elsewhere. The largest and most important glaciers of the Himalayas show very little retreat at this time.
