Though this is a very small part of the change of global energy content, it is regionally important and investigations into the cause of sea ice need to pin down the sources of this energy.

How many times have you seen the word «collapse» used lately to describe what could unfold should human - caused global warming, and more particularly warming seas, erode the West Antarctic Ice Sheet?

Even with the increasing summer retreats of sea ice, which climate scientists say are being driven in large part by global warming caused by humans....

I've been criticized by some environmentalists in recent years for writing that the long - term picture (more CO2 = warmer world = less ice = higher seas and lots of climatic and ecological changes) is the only aspect of human - caused global warming that is solidly established, and that efforts to link dramatic weather - related events to the human influence on climate could backfire should nature wiggle the other way for awhile.

Although again I challenge you to name even five polar scientists who do not think human - caused global warming is the dominant cause of «the increasing summer retreats of sea ice.»

However, I've never seen a single media article in any U.S. press outlet that covered these issues — the large - scale evidence for global warming (melting glaciers, warming poles, shrinking sea ice, ocean temperatures) to the local scale (more intense hurricanes, more intense precipitation, more frequent droughts and heat waves) while also discussing the real causes (fossil fuels and deforestation) and the real solutions (replacement of fossil fuels with renewables, limiting deforestation, and halting the use of fossil fuels, especially coal and oil.)

But as a starting point, I'll propose now — and I'll change this if they disagree — the names of some leading scientists in this field who would NOT say there is sufficient evidence to conclude that human - caused global warming IS the main cause of increasing summer retreats of sea ice (although they would say there is strong likelihood that it will eventually dominate):

Because ice sheets contain so much ice and have the potential to raise or lower global sea level so dramatically, measuring the mass balance of the ice sheets and tracking any mass balance changes and their causes is very important for forecasting sea level rise.

In theory, if a large mass of glaciers or ice sheets melted, this could cause a global sea level rise.

Sea level rise is caused by the melting of polar ice caps and the expansion of water when it is warmed, both triggered by global warming.

Similarly, if glaciers or ice sheets expanded, this could cause a global sea level fall.

To assess these implications, we translate global into local SLR projections using a model of spatial variation in sea - level contributions caused by isostatic deformation and changes in gravity as the Greenland and Antarctic ice sheets lose mass (36 ⇓ — 38), represented as two global 0.5 ° matrices of scalar adjustment factors to the ice sheets» respective median global contributions to SLR and (squared) to their variances.
