The melting of sea ice, ice caps and glaciers across the planet is one of the clearest signs of global warming and the UK-led team of scientists will use the data from CryoSat-2 to track how this is affecting ocean currents, sea levels and the overall global climate. Scientists have already shown that the amount of sea ice in the Arctic is falling, and the latest data confirms the long-term trend. But some data also suggests that the ice that remains is thinning. If the measurements from CryoSat-2 bear out this thinning theory, it would mean the ice is being lost more quickly. Scientists are concerned that the loss of sea ice is leading to a feedback effect where the newly exposed, darker ocean absorbs more sunlight, warming the water yet further. In addition, sea ice can block glaciers on land from falling into the ocean, so its loss could raise sea levels.One has to be deep in denial to ignore the evidence that climate change is happening....
