Polar Region Sea Ice

Technical Rating: star
Here is a series of real time graphs of sea ice extent in the Arctic and Antarctic regions, as globally measured by satellites.



Climate Alarmists are Rescued from Antarctic Summer Sea Ice

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.



Antarctic Ice Expansion Shows Climate Models Are Unreliable

Despite a 20 percent increase in atmospheric CO2 over 40 years, and model predictions to the contrary, sea ice in the Antarctic has expanded for decades. Such observations are in direct opposition to the model-based predictions of the IPCC. This should give pause for thought about climate alarmism in general. The IPCC report predicts a multi-model average decrease of between 16 and 67 percent in the summer and 8 to 30 percent in the winter by the end of the century (IPCC, 2013). Models simulations give a 1 million sq. km reduction is sea ice, but measurement show a 300,000 increase from 1980 to 2005 due to falling temperatures.



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.



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.
