Ocean warming may be a major driver of sea-ice expansion in the Antarctic, researchers report today in Nature Geoscience1. While sea ice at the North Pole has shrunk substantially over the past three decades2, scientists have struggled to explain why sea ice near the South Pole has grown in extent over the same period3.
“The paradox is that global warming leads to more cooling and more sea ice around Antarctica,” says Richard Bintanja, a climate researcher at the Royal Netherlands Meteorological Institute in Utrecht. Bintanja and his colleagues show that enhanced melting of the Antarctic ice sheet — which is losing mass at a rate of 250 gigatonnes yearly — has probably been the main factor behind the small but statistically significant sea-ice expansion in the region.www.nature.com/ngeo/journal/v6/n5/full/ngeo1767.htmlwww.nature.com/news/global-warming-expands-antarctic-sea-ice-1.12709 What percent of Antarctic ice mass is 250 gigatons? Wonder if it is within error bars of mass calculations? They make it up as they go along, and Numerouno is more than willing to follow. Don't forget, first it was melting Arctic ice would cause warmer NH winters with less snow, then when that didn't pan out so well for the past five years, the "experts" simply changed it to less ice equals colder snowier winters. How are they going to explain this winter? hockeyschtick.blogspot.com/2013/05/new-paper-finds-antarctic-sea-ice.html |

Karlox, I am not a big fan of graphs. You really have to look at where they start and why they don't go back further in time when the data is readily available. For example it looks like we are heading for another ice age if you look at global temps from 1997 until present. Looks like were going to burn up if you look at one from 1979-1997. The state climatologist from Texas has a pretty good blog entry about graphs of CO2 and Temps. blog.chron.com/climateabyss/2012/10/carbon-dioxide-and-temperature/ |

How long is history and when should I look at it? "John von Neumann" "With four parameters I can fit an elephant, and with five I can make him wiggle his trunk. ..." link |

One of the magical properties of the CO2 molecule is that it allows trends which favor AGW theory to go up to infiniti or down to ). So, temperature trends will climb as far into the future as the crystal ball allows us to see. Sea Ice will spiral downward until it is gone. Amazing stuff, this carbon dioxide.

Unfortunately not.............currently Anarctica has a record ice up to date!!It has set all-time new record high!!19.512 million square km's and continues to trend up!!

But that record occurred only because both the sea and water temperatures are increasing in the southern ocean, changing the wind patterns. And besides, the average inland temperature in Anarctica has gone from -36 degrees C to -34.5 degrees C, thereby creating the conditions for unprecedented melting of the southern ice sheet. As I said above, magical stuff, that CO2.

I don't. I want the cold to stay up north for a longggggg time this year.
