There won't be much, if any, coverage in the media about the unprecedented high in the Southern Hemisphere sea ice anomaly, so a self-explanatory graphic is posted below of the 1979 to present anomaly from the 1979 to 2000 mean:
We will, of course, be hearing about the extent of the Northern Hemisphere sea ice during the summer, which has bounced back over the winter from its record low. See the graph below of the anomaly for 1978 to present from the 1978 to 2000 mean:
I'll finish with a graphic of the un-exciting 1979 to present global sea ice anomaly trend (in red) from the 1979 to 2000 mean (in black), and the global daily sea ice anomaly (in blue):
The graphs are from The Cryosphere Today
Why are the graphs starting with 1979? Why not 1936 or so when conditions were similar to today?
Paul - Because that's when the satellite records begin.
Doesn't it occur to anyone that the reason sea ice is shooting up is because the glaciers that have been held back until now are slipping into the sea?
Unless I hear otherwise from a reliable source, this is cause for alarm in my eyes.
Nope not suggesting that at all. It's important to not confound data sets. And yep Europe does enjoy the benefits of warming circulations.
But looking at many different data sources there is quite good evidence that "much" of the world has seen a warming trend.
Antarctica and the SH should be different. More ocean in SH And Antarctic circulation, particularly of recent years, tends to wall the continent off.
And the same argument you're using needs to done for rainfall in Australia - overall rainfall no trend - but regionally we have significant deficits in some areas - east, south-east, south-west and areas that have become wetter (north-west).
The warming itself is not the real issue - it's what happens to the extremes !
If even the boy wonder is now suggesting that we treat Antarctica differently to the Arctic, can we conclude that he now agrees that there is no such thing as 'Global' warming?
Surely, those nations that border the North Atlantic have an issue with 'regionalised warming' that will produce both adverse and beneficial impacts as climatic variation always has done.
"I was wondering why there has been no response".
What can you say? The poor fool is a day late and a dollar short. More to be pitied than despised.
Hello, I posted this over on Watts website but this seems the perfect place to post it as well. I was wondering why there has been no response on any of the blogs or websites about the following news story that was just released about scientist predicting another major artic ice melt this year.
here is the link to the story
