Here’s hoping for no October climate surprises…

Carry on. Usual rules.

To come this month: Arctic sea ice minimum, decisions from the IPCC scoping meeting on a report focused on the 1.5ºC target, interesting paleo-climate science at #ICP12 and a chance to stop arguing about politics perhaps.

Usual rules apply.

Sorry for the low rate of posts this summer. Lots of offline life going on. ;-)

Meantime, this paper by Hourdin et al on climate model tuning is very interesting and harks back to the FAQ we did on climate models a few years ago (Part I, Part II). Maybe it’s worth doing an update?

Some of you might also have seen some of the discussion of record temperatures in the first half of 2016. The model-observation comparison including the estimates for 2016 are below:

It seems like the hiatus hiatus will continue…

A week is a long time in politics climate science: Nonsense debunked in WaPo, begininngs of recovery in the ozone hole, revisiting the instrumental record constraints on climate sensitivity…

Lots of lessons there.

Usual rules apply.

June already? Cripes…

Usual rules apply.

This month’s open thread. Usual rules apply.

This month’s open thread. Standard rules apply…

This month’s open thread. Pros and cons of celebrity awareness-raising on climate? The end of the cherry-picking of ‘pauses’ in the satellite data? Continuing impacts of El Niño? Your choice (except for the usual subjects to be avoided…).

This month’s open thread.

Just so you know, a lot of people have complained that these threads have devolved – particularly when the discussion has turned to differing visions of solutions – and have therefore become much less interesting. Some suggestions last month were for a side thread for that kind of stuff that wouldn’t clog interesting issues of climate science. Other suggestions were for tighter moderation. The third suggestion is that people really just stay within the parameters of what this site has to offer: knowledgeable people on climate science issues and context for the science that’s being discussed elsewhere. For the time being, let’s try the last one, combined with some moderation. The goal is not to censor, but rather to maintain somewhere where the science issues don’t get drowned out by the noise.

Happy New Year, and happy new open thread.

As per usual, nuclear energy is off-topic – it’s not that it’s uninteresting, but it ends up dominating conversation to the total exclusion of everything else and just becomes repetitive and dull. Recent excursions on this topic shows what happens when we relax the moderation, so back to being strict about this. If you want to discuss this, please go somewhere else.
