Arctic Sea Ice Hits Record Low 370

Posted by samzenpus

Titus Andronicus writes "Angela Fritz and Jeff Masters of Weather Underground analyze this year's record ongoing Arctic ice melt. Arctic sea ice extent, area, and volume are all at record lows for the post-1979 satellite era. The ice is expected to continue melting for perhaps another couple of weeks. Extreme sea ice melting might help cause greater numbers of more powerful Arctic storms, help to accelerate the melting of the Greenland ice sheet, and help to accelerate global warming itself, due to the increased absorption of solar energy into the ocean."

    It's here. Let's deal with it.

      You first.

      That is the problem. Everyone wants *everyone else* to deal with. As long as they can still drive to work with cheap gas and get a shiny new smart phone every year, its clearly other peoples real problem... if only they would deal with it right?

      So what are you doing to deal with it?

    It is time to accept that this is happening. Time to make the most of it. There are remote communities that will be well positioned in the Canadian Arctic for incredible economical opportunities.

    It may well be too late to stop the warming trend, we will have to make the best of it.

    As the Arctic Ocean summer ice declines there is developing evidence it is having an effect on the northern polar jet stream, slowing it down and causing the meanders to get larger. This has the effect of bringing colder weather further south and warmer weather further north and slowing down the speed at which the weather moves through. That would explain why a few years ago when Florida was having freezing weather Greenland was practically balmy.

  • As earth heats up, cooling mechanisms should increase. It's not instantaneous of course. Until the cooling mechanisms outpace the heating mechanisms, ice is going to keep melting year after year. The speed ice melts probably has more to do with surface area, ice depth, and cloud cover more than ambient temperature.

      And which cooling mechanisms are these? According to TFA, melting the polar icecap actually removes an important cooling mechanism. Other mechanisms, such as the ocean's ability to abosrb CO2, are pretty much maxed out. Do you have a planet size air conditioner nobody else knows about?

There are running jobs. Why don't you go chase them?
