You started it off by saying the man made influence was debateable and then went on to talk about events thousands of years ago. Why is it debateable? But the deforestation and the millions living on flood plains with poor defence from floods are what caused the headlines. I will not read anything about glacial true pictures as I do not believe what scientists are telling us any more.

That is the point, myself nor you or anyone else can prove or disprove anything about the weather because it is ever changing. I am not mixing up weather and climate I would say you are, as weather leads to climate and settled climate is dismantled by unsettled weather. But mans unfluence on the weather and therefore the climate is paltry compared with natural events. We learn to live with the weather not the other way round. So technical language and figures can be twisted whichever way you want but no one can predict the weather or the climate. We can however follow forecast trends but these are always volatile as we have seen this December. And they are short term forecasts. Yet global warming is backed up by forecasts of weather and climate 40 to 100 years hence. As I said - what tosh. In any case we are heading to a zero carbon emission world in the coming decades so mans affect on CO2 will be reduced to zero.

You are prevaricating. You did not predict the record December cold nor can you predict the cold to come in the next three months. You can't predict the state of the Arctic or the Atlantic even one year from now yet alone 100 years. It is called the weather. Hiding behind technical references means nothing to Mother Nature and her turbulent and chaotic personality. Global warming then climate change and now the extreme cold is caused by global warming - what tosh. No one knows.

Exactly how are we impacting on the Atlantic? It is the failure of the Atlantic to break through that has allowed the current cold weather. You did not predict the current cold in the UK and yet you predict events 100 years from now.

Arctic sea ice is surely totally irrelavent. It neither adds to rising sea levels should it melt or decrease sea levels should it freeze. It is totally a physical indicator of the coldness of the arctic waters at varying times of the year. Nothing more. The southern extent of the jet stream must influence the air temperature in that the arctic air will be warmer as the cold air shifts down south. If the jet stream moves north this must lock the cold air into the arctic. However is the sea ice not susceptible to salinity and ocean current from storms in the Atlantic? The Atlantic is the biggest influence on western northern hemispere weather. And cannot be affected in any way by mans interference.

Actually Groenland may be so named due to the green of the lower parts of Greenland in the summer. The ones not covered by glaciers.
