Arctic Summer Could be Ice-Free by 2105

I find this disturbing (reading the link below) to say the least, many other reports say once all the ice is gone and the earths oceans even out in temperature then the oceans currents will slow if not stop, this will cause an even wider range of problems.

don't want to sound stupid but can we fix it??

It is, but I've read stuff that indicates things could go the other way; that's to say, that the warming could eventually trigger cooling of the Northern Hemisphere, and the ending of the current interglacial period. This, so I've read, would be caused by the increased precipitation — a result of warming — reducing salinity in ocean surface waters, and so shutting down the circulation in the Atlantic that warms Northern latitudes. Actually, it's way more complicated than that, but I don't know all the specifics.

Interestingly, the cycle of glacial/interglacial periods is also influenced by various parameters of the earth's orbit around the sun, these act over cycles varying from 10's to 100's thousands of years. However, the climatic shift from interglacial to glacial these influence tend to occur relatively quickly, in the order of decades, so it's believed. Going on previous evidence, the current interglacial period is due to end fairly soon; of course soon could be a hundred, or a few thousand years! Anyway, the consequences of that would be equally dramatic. For example, during previous glacial periods, parts of N America and the UK would have been coverd by ice sheets over a mile deep.

So, we're f****d which ever way you want to look at it! It is fairly safe to say, though, that mankind has to look at climate change of one form or another as inevitable. When it happens, whether glaciation, or flooding of vast areas of land due to melting of ice-sheets, the consequences will be catastrophic.
