There is a lot of buzz right now about Trump and discussions about N. Korea. (April 24, 2017)

Some of us have picked up articles about substantial numbers of US vessels transiting the Canal starting a few days ago.  I've found some in various Spanish language site, but am keen to find as close to original source as possible.  I'm suspicious english language search engines may not be picking up the threads on this; certainly our news outlets are not.

Here's an example of what I found:

Greetings;  Started this as a placeholder to start capturing posts on this topic which have ended up in unlikely locations.

Greetings all;

I was recently challenged by someone regarding the observation that 2015 extent is the lowest for the date in the current record.  The individual tried to draw me into a fight (on someone else's page), which I refused for propriety's sake.  Among the things he asserted and posted was this:

http://adsabs.harvard.edu/abs/2007AGUFMPP11A0203F

He was using that to defend an assertion that 5-7000 years ago the Arctic was hotter, and that the current changes were no big thing.

I'm curious as to what people have to say about this, as I've got little understanding of it.  My gut says that the conclusions are (1) unsupported and/or (2) being misrepresented.  I'd rather not argue from my gut, however.

Feedback would be appreciated.

Greetings all;

The National Climate Assessment has been released.  Link here for access and download of a rather voluminous set of documents.

Arctic sea ice / Fracturing event, Two point Oh

Last year late January/February, a fracturing event started in the Beaufort.  Thanks to Apocalypse4real, we have an image from last February 8th:

At the time there was considerable expectation that this was dire news for the pack. But then came a cold spring and cool summer, and the ice was saved, against most peoples expectations.

Now, forward to the present.

Here's what it looks like currently:

It seems to me this breakup is starting about 30 days earlier.  Predictions, anyone?
