Arctic Ice

Sorry, but this one is eating a hole through my chest

Note please the difference in ice thickness.

Keep in mind last year was a record thick year.

Cats cats cats.; I use the internet and I like cats.



This dude; clearly doing it all wrong. I see that trampoline in the background! Get those cats doing backflips! If the world could see ocean currents as cats doing backflips I think they might actually pay attention. I mean seriously Mr. Beckwith, what do you spend your time on!



Oh, right.

More thought for food? More COP20

This guy has been thinking about other things. Particularly - Economics in the age of Climate Change

Alright seriously, The computer is going off for a few days.

I've got a great Idea for a function stacked fence and I want to play with some fire.

Lets get cracking on this stuff, aye?

I'm wondering if I should be expecting some really warm wet winds coming out of the southwest at some point. A strong storm surge like that would annihilate me utterly. I need a couple hemlocks half down I fear and its like playing tetras to fell them now that house have grown up all around them. Luckily I know several very skilled tree fellers. But they ain't cheap. :/


So like talkin' bout the weather and stuff. Probably should get into one thread at some-point or something maybe?

Some map based stuff maybe? Anyone else interested in a thread discussing that sort of thing?



Current Ocean Surface Temperature Anomalies.

I'm looking at that Atlantic edge and wondering whats going on there.


Edits: Maps and comment changed and retooled

Professor Paul Beckwith of the University of Ottawa gives an update of currant climatic and Arctic conditions filmed a couple days ago. Part one looks at sea surface temperature anomalies and atmospheric pressure. Part two deals with polar ice and jet streams.






Edit: Added video for part 1.

At risk of turning straying from topic and turning this into yet another long-think hypothetical vs reality climate thread;

Here's Guy McPherson trying his absolute hardest not to scare people. It's his best lecture I think for anyone who likes to get peoples succinct opinions and perhaps forward and discuss such matters.

Landon I don't know if you have access to the HBO weekly docu-news show VICE that airs on Friday nights. But the most recent show ("Our Rising Oceans") looked in part at ice melting patterns in Antarctica. The emotional moment for me was when the interviewer and an unflappable-sounding ice scientist were discussion things while on board the NASA DC-8 that measures glacier/icefield ice thickness with lasers (bouncing off the top) and radar (bouncing off the earth beneath the ice). Some frightening datum about missing glacier ice caused the interviewer to say "You're telling me this is a 'Holy Shit' moment, aren't you?" And the interviewer nodded calmly and said "Actually we're way past 'Holy Shit' now..."

The thing I learned from the episode is that tracking the extent of sea ice isn't even all that relevant compared to watching changes in the thickness of glaciers and ice fields. Sea ice is rarely more than a meter or so thick, whereas some of the continental ice is closer to a mile. All the sea ice melting hurts us a lot less than when the glaciers go, as they are beginning to do in Antarctica and Greenland. (Of course, it's a different story for arctic bears.)

To get back on topic. Here is a 50 minute lecture on the Cryosphere and current Arctic and Antarctic data and models by Jim White of the University of Colorado Bolder at the American Geophysicists Union fall meeting held December 2014. A very clear, concise, informative, and humorous presentation on this pressing subject.

Dan it's funny you mention this.

I just posted a recent American Geophysicists Union lecture on the subject of Arctic and Antarctic ice. I will poke around for the VICE pay TV spot.

That Vice episode I mentioned is available in full on YouTube right now. But I don't think it will stay for long; the Vice page dated March 11 says they'll be streaming it "for the rest of the week" whatever that means.
