In perioada de vara suprafata inghetata scade dar anul asta a scazut mai mult decat oricand.

The sea ice minimum in the 1970s was 5.5 million square kilometers. Then in the 1980s it was 5.0 million square kilometers. Then in the 1990s it reached 4.5 million square kilometers. Then by 2005 we touched 4.01 million square kilometers as the prior record.
Then comes 2007. Oh my, does 2007 come roaring by! On August 9, 2007 we set a new record low of 3.98 million square kilometers! But just 19 days later we set a new minimum of 2.99 million square kilometers.
Did you get that yet? We lost one million square kilometers of sea ice in 19 days. People told me in email that I was nuts for projecting a sea ice free arctic by 2010 but guess who is laughing now? The jackasses out there still refuse to acknowledge that we are in a positive feedback loop. The change in sea ice level is definitely not linear yet the IPCC still refuses to model it any way except linear! And all of that open water is dark color and absorbs yet more heat rather than white and reflecting it away. What is this doing to the Greenland ice sheet? Anyone care to speculate? It sure is not going to make that ice sheet colder or more stable!

Puteti da play la siteul de mai sus si observati cum 1 milion de km patrati de gheata dispar in 19 zile.
Gheata reflecta razele soarelui, marea libera le absoarbe. Cu cat e mai putina gheata cu atat zona se incalzeste mai repede cea ce duce la si mai putina gheata cea ce duce din nou la mai multa mare libera etc
In ultimii ani inghetul a inceput tot mai tarziu si apoi dezghetul tot mai devreme
