@Sam
the chart itself doesn't merely ignore feedbacks; it ignores CO2.
notice at the bottom, imagining a 'sudden stop' to CO2 emissions in 2016, the temperature immediately starts to drop. this, despite the lag in warming that occurs after CO2 emissions.
even if we stopped right now, even if feedbacks such as methane etc didn't occur, the earth would still warm for decades just from the GHGs we've pumped out recently.
in short, there's no way we're staying below 1.5C, and pretty much no way we're staying below 2C. to stay below 3C we'd have to wholesale change all of industrial society very quickly AND feedbacks from desertification to methane release would have to magically not occur.
Perception of the Arctic 2
Like I've written in the previous blog post with the same title, I'm not just interested in the science/ observation of Arctic sea ice and the consequences of its loss, but also in the question how and how far these events are finding their way to the collective consciousness. Are people becomi...
speaking of trollery!
Arctic sea ice extent is the highest since 2006
2009 aside, the good thing about the chart above is the trend line is easy to follow. if extent this year turns out to be 5 million km^2, it'll be right smack on the trend line, which anyone can tell is going down, down, down.
Arctic ice loss and armchair scientists
John Abraham, known as the dragon that slew the Viscount and an excellent climate science communicator, approached me a while ago with a couple of questions concerning the blog and Arctic sea ice in general. He turned it into this ego-inflating article on the Guardian website: Global warming, A...
i concur, well-deserved.
This blog has been practically troll-free for three years.
well, it helps that you keep the site clear of drive-bys etc. nothing worse than seeing a good discussion site get mired in responding to consistent trollery.

@Neven,
off-topic Gish Gallops
i like to think of a big bag full of a gish-gallop of bafflegab.
a "gish-gafflebag" if you will.
Third storm
Are we getting used to this? After the persistent cyclone in May and June, and the spiffy, but short-lived cyclone of two weeks ago, the Arctic is visited by yet another intense storm that goes below 980 hPa. In fact, according to Environment Canada it is currently at 976 hPa, which is lower tha...
the PDO may be switching to a cooling phase?

LOL. "This is a science board, so let me quote Anthony Watts..."
That's the best joke I've heard all day.

Yeah, the cracking from Morris Jesup is basically merging with that coming across the Lincoln Sea. I had hoped the MYI around Lincoln would hold faster than this.
this is truly amazing to watch in real time. kinda horriying, but amazing nonetheless.
Crack is bad for you (and sea ice)
The previous pun - cracks of dawn - was wearing off, and the comment section was getting full, so here's a new pun and blog post dedicated to the cracking event that started in the Chukchi and Beaufort Seas a couple of weeks ago, and then moved on to the multi-year ice against the Canadian Archi...
NeilT, actually CT is now showing a new record low of <2.24.
ugh.
Joe Bastardi found a cherry
Now that fake skeptics have dropped the IMS sea ice extent chart to call the results of this stunning melting season into question, Joe Bastardi comes up with another try (hat-tip to Chris Biscan) to imply that the melting season is over, something that is wanted so desperately by fake skeptics ...
Seke Rob - I tried all morning, but it just came back online.
2.59m k^2. ugh.
Why Arctic sea ice shouldn't leave anyone cold
The sea ice is leaving us a bit more every year. It's time to start contemplating its absence, which is why I teamed up with Kevin McKinney to write an extended version of the shorter piece you might see pop up here and there. Because you know, disappearing sea ice isn't without consequences. An...
