Letter: Vast losses of sea ice

The letter titled “About that warming” (Monitor, Jan. 1) pokes fun at climate researchers being stuck in ice in Antarctica. As NASA can confirm, there is less sea ice globally than 30 years ago; the small increase in overall ice in Antarctica does not compare to the vast losses in the Arctic.

Researchers at NASA, UCLA, and the University of Colorado have uncovered an increase in the westerly winds surrounding Antarctica, which has the effect of expanding the outer edge of sea ice. Scientific studies have also determined why the winds have accelerated.

First, global warming has changed temperature differences between the poles and equator, creating stronger winds. Second, ozone absorbs sunlight, and with the human-induced hole in the ozone layer, there’s a colder stratosphere over the southern pole, affecting wind patterns, according to University of New Zealand experts.

As the atmosphere contains 4 percent more water vapor than 30 years ago, increased precipitation is another factor. Science is amazing when we seek to understand it.

The proof that the Gorebull Warming Alarmists are nothing more than a cult religion lies in the good news. When presented with irrefutable facts that the earth has not warmed going on 17 years 4 months they do not find that news as something to be celebrated. NOPE ..... they create lies like "the oceans ate my warming". A MUST READ on this subject is : "The Global Warming Tipping Point is Near" by Andrew Thomas - http://www.americanthinker.com

This is a great point, Susan-- thanks for posting this!

HEADLINES: "Global Sea Ice Area Closing In On Record High" Posted on December 21, 2013 by stevengoddard Global sea ice area is second highest on record for the date after 1988, and closing in the #1 spot. Antarctic ice is melting very slowly this summer, due to record cold Antarctic temperatures.

Vast losses of sea ice..in the arctic...from 30 years ago???... no...

Sadly, yes. If only it were true that climate change was a crock. But you're misinformed and wrong again. Mass and area are different. The Arctic has been losing ice mass for a long time, as the graphs in the link show. Extent varies more from year to year, but it's thinner and younger ice. You'd know this if you were following the science, and not just interesting in contradiction. Likewise the Antarctic is losing land ice mass, while sea ice mass is increasing for reasons deniers will surely find incredible--the sometimes surprising and counter-intuitive changes that accompany global warming. http://www.cgd.ucar.edu/staff/mholland/papers/holland_etal_simba.pdf http://www.skepticalscience.com/feb-2013-sea-ice-spiral.html http://www.nasa.gov/topics/earth/features/earth20130613.html#.UsedkhY70b0 http://www.skepticalscience.com/antarctica-gaining-ice.htm

Thirty years later we are still pursuing this project. We have developed a 30 years time series of glacier mass balance on glaciers across the North Cascades of Washington." http://neven1.typepad.com/blog/2013/12/building-a-30-year-glacier-mass-balance-time-series.html
