Arctic and Antarctic Ice Growing

Vice-President Al Gore, in his 2007 Noble Prize acceptance speech, said,

“The North Polar ice cap is falling off a cliff … It could be completely gone in summer in as little as seven years. Seven years from now.”

However, the apocalypse didn’t happen.

Antarctic ice is also growing.

As a result, both the North and South poles are seeing more ice.

These NASA satellite pictures of Arctic ice cover for 2012 and 2013, show the one-third increase in ice cover during that year. And, it has grown more since then.

Satellite pictures of the ice caps only go back about thirty years, so it’s impossible to know how the ice caps behaved in earlier years.

Making wild claims about the melting of the ice caps is irresponsible, as recent data has shown.

For example, the Canadian research ship Amundsen had to be diverted from its carefully planned summer research program, because it was needed to break ice in Hudson Bay for resupply vessels.

“Johnny Leclair, assistant commissioner for the Canadian Coast Guard, said conditions in the area are the worst he’s seen in 20 years.”

This graph shows that Arctic sea ice is only slightly below the average from 1981 – 2010.

As can be seen in the following graph, ice in Antarctica is greater than the average over the same time period.

The West Antarctic Ice Sheet is an area that needs to be monitored because ocean currents under the ice may be able to loosen the ice sheet and cause it to break away.

Global warming alarmists have claimed global warming, caused by CO2 emissions, would increase the likelihood that the ice sheet would break away and result in dramatic sea level rise.

But, it has long been believed, and recently confirmed, that geothermal activity on the ocean floor or beneath the ice sheet is the actual source of warming.

The latest study, led by UC Santa Cruz researchers, with results published July 10 in Science Advances, shows very high geothermal heating from the ground beneath the West Antarctic Ice Sheet.

The geothermal heating confirms there could be a future problem with the ice sheet melting, but it won’t be because of global warming from CO2 emissions.

The recent rapid recovery of Arctic ice cover and the continuing buildup of Antarctic ice in the face of higher atmospheric CO2 concentrations, demonstrates that climate change doesn’t represent a threat to the ice cap at either pole.

Global warming alarmists can no longer claim CO2 emissions are a threat to polar ice caps.

If there is an eventual threat to the West Antarctic Ice Sheet, it’s from geothermal heating, not global warming.

  1. The Santa Cruz paper stated that the volcanic heart source under West Antarctica had long been present with no direct evidence of having melted land ice previously. Without knowing more about the volcanic heat, it is difficult to say how much it contributes to current glacier melting, which some workers ascribe to undercutting of ice shelves by warmer sea water. (Of course, part of Went Antarctica glaciers did melt in the last interglacial about 120 thousand years ago, when global temperatures were higher.)

    • Thanks. Yes, more information is needed before reaching any absolute conclusions about the future of the West Antartica ice sheet. It’s reasonable, however, to say that CO2 induced global warming isn’t playing a major role in any warming.

  2. Donn,
    PLEASE respond to President Obama’s recently released EPS Clean Power Plan.
    Thanks,
    Your McLin supporter

    • Thanks.
      I’ll have a quick response next week or so.
      The entire Clean Power Plan is complex, so I will have to be careful how to communicate critical components in a way that is easy to understand.
