More hot summers, fewer cold winters. More of one extreme, less of another.

It has been clear for some time that climate change is a defining social, and therefore political, issue for the twenty-first century... the core science is solid, and policy-makers at all levels have a responsibility to engage with it.

What the hell does Nature know about science?

(Yes, I know it published the STAP cell debacle but that was one paper, not an editorial stance)
A Republican US presidential candidate speaks on climate change, but will his party listen?

Not that the hiatus would have changed anything.

Deniers couldn't explain the supposed hiatus any better than anyone else. More importantly, they couldn't explain why temperatures weren't coming down.

If it didn't happen, it's amazing how much effort climate scientists put into explaining it. With enough parameters you can always make the theory fit the data. With enough judgement calls on estimating the data, you can almost always make the data fit the theory.

I don't have an explanation of the mechanics of the pause, although I've seen some candidates. But the pattern looks pretty clear if you look at global temperature for the past century+. It looks like a rising line from AGW with an oscillating term superimposed with a period of about sixty years. That gives you thirty years of rapid warming from about 1911 to 1941, thirty years flat to cooling until about 1971, thirty years rapid warming until about 2001, then again flat.

I don't have a model, although the obvious guess is that it has something to do with atmosphere/ocean interactions. But considering that the IPCC with its models has, on average, done worse at predicting warming than a straight line extrapolation of the trend from 1911 to the first IPCC report, extrapolating the past pattern seems like a reasonable approach. If it's right, the current pause should last until about 2031, followed by a renewed period of rapid warming. Whether the current AGW orthodoxy can survive that long I don't know.

My serious critique of the current orthodoxy is on the consequences of climate change, not the pattern, but the above strikes me as a reasonable guess at what's going on.

The last one is post-transition metals, btw.

48ºC!
 
Massive heat wave in #India kills at least 350 people http://bbc.in/1LAGIrA
More than 350 people are reported to have died in a heat wave sweeping India with temperatures reaching 48C (118F) in some areas.

If you're anti-nuclear, you're pro-coal.
Experts suggest that without nuclear power the world has little chance of restraining global warming to less than 2 degrees Celsius

This is a fascinating account of flying from London to Tokyo, from a pilot's perspective.

"What do chemists do anyway?"
 
To mark the RSC's public opinions of chemistry survey, (the results of which can be viewed here: rsc.li/1ctzp8n) Dr Mark Lorch of the University of Hull has put together his top 5 chemistry inventions that enabled the modern world (for which I put together this summary graphic): https://goo.gl/4w3Sh1

In addition, there's an old graphic on antibiotics here: http://goo.gl/6d7V2c
One on contraceptive pills here: http://goo.gl/8E6xPt
...and one on plastics (including polythene) here: http://goo.gl/S92ued

What chemistry inventions would make your top five?
