Davy51 Posted November 19, 2019 Report Share Posted November 19, 2019 Perhaps intense undersea mining for cobalt for electric cars etc will reduce sea levels sufficiently to give the planet a few more thousand years. 2 Quote Link to comment Share on other sites More sharing options...
Evil Sid Posted November 20, 2019 Report Share Posted November 20, 2019 Don't worry I am sure the yanks will sort it all out. They beat godzilla , blew up several asteroids and defeated two alien invasions on independence day. Just a pity John Wayne is not alive we would be safe as houses. Did he not tame the west and win two world wars as well.🤔...🤠You need to ask is there more water now or less water now than say 3million years ago. Or is there the same amount of water. if there is more where has it come from and how did it get here. There should be roughly the same amount of water, less a small amount that may leech out into space. The problem seem to be that it is now in less solid state. Only the ice that has formed on land will affect the water levels. ice that is already in the water will not raise the water level even if it does melt. it maybe that it is not the sea levels rising but that the earth is shrinking and forcing the water levels to rise as a result....🤫 Quote Link to comment Share on other sites More sharing options...
Confused52 Posted November 20, 2019 Report Share Posted November 20, 2019 Sid, There is no more water. The claim is simply that as the oceans warm the water expands and take up more space so the sea levels must rise. We measure ocean temperatures using water in a bucket, or some floating Argo beacons else from space with Infra Red sensors. In every case we get the surface temperature. Since the oceans are very deep there will be a temperature gradient to the ocean floor and currents either will or won't mix the warm and cold water. However it seems unlikely that estimating sea level rise by extrapolating surface temperature effects to a body of water as massive as the oceans when we don't understand how they work is going to be accurate. But hey you can make up scary numbers really easily! 1 Quote Link to comment Share on other sites More sharing options...

The area of land is growing in the Pacific not shrinking. If we do have a warmer climate, then it will rain more, more rain means deserts will shrink, there will be more vegetation and trees will grow faster which will hold huge amounts of water Quote Link to comment Share on other sites More sharing options...

Observer II Posted November 22, 2019 Author Report Share Posted November 22, 2019 Someone found a photo of some kids, from 1878, which showed a double of Greta; leading to speculation that she's a time traveller !  If so, has anyone calculated the carbon footprint of her time machine. !    😑 Quote Link to comment Share on other sites More sharing options...
Evil Sid Posted November 23, 2019 Report Share Posted November 23, 2019 I will have been dissipated evenly over the 140 years since that photo was taken...🤠Quote Link to comment Share on other sites More sharing options...
