I have just joined the group and have found it quite accidentally. I have had a keen interest in the weather and global weather, as I am an astronomer.
I have for years been studying the Antartic Ice pack and the El Nino and El Nina effect.
About 4 years ago, I predicted that the Antartic Penninsula's ice will start disappearing due to Tectonic Plate movement and a shift in ocean currents.
This has come to be and now we have the phenomina that the Pacific warmer waters are getting into the South Atlantic and moves to the Northern Atlantic causing massive tempreture changes.
This was based, purely on images from various satelites and information on the web.
I also have opinions on Global Warming and I do NOT support the Ozone Hole panic of the Greenies.
Hope to have some good converations and discussions.

Sea water in the Antarctic certainly seems to be warmer than before. Where the bottom of the Antarctic ice cap rests in sea water rather than on solid rock the warmer water is melting the ice from below, destabilising it. This is what's happening in Western Antarctica where large ice chunks are breaking off.
But where the Antarctic sheet rests on solid rock it is probably thickening because precipitation has increased. There won't be much, if any, melting of this area from above because the air temperature is so very low all year round. So I think the East Antarctic sheet will remain in place and solidly frozen for a long time to come, except perhaps at the very edges where there's contact with sea water.
