No, we don't. What we do know is that the increased heating as a result of GHGs in the atmosphere have, in effect, put the climate on the equivalent of steroids. Just as you never know which races an athlete on steroids might have won as a result of being on steroids, you never know which weather events were caused by…

I hope you have some great smalltalk-free geek parties.

You clearly don't get it. We don't have time. If you look at anything up to and including RCP4.5, they all include technology that would allow us to sequester 10 billion tonnes of CO2 annually, for decades. At anything over RCP 4.5 you go over any hope of staying below the threshold at which forests turn from a carbon…

Urgently phasing out all fossil fuel use and shifting our diets down the food chain. We have the technology for that, even if the deniers like to pretend that we don't, or that it will be "too expensive" to implement.

The American delusional fantasy sold to make you all believe that the poor are all either lazy (the other guy) or temporarily embarrassed millionaires (you).

Hopefully not like this murdering SOB:

This assumes equality of opportunity, which anyone who pays the slightest attention knows that you don't have - because the fact that the right to swing your fist ends at someone else's nose is lost on most people in the US, particularly the libertarians.

The holes are only one symptom. What's happening in the high North is frightening.

Plenty of rain here. Not a lot of snow in the central belt, but plenty of rain. It's raining right now.

Your points do not stand, and I've seen them made by deniers before. The best they can do is provide links to denier blogs, or "research" conducted by shills like Willie Soon, lengthening the time before we take the critical action needed to stop climate change.

"I may remark that the curious transformations many formulae can undergo, the unsuspected and to a beginner apparently impossible identity of forms exceedingly dissimilar at first sight, is I think one of the chief difficulties in the early part of mathematical studies. I am often reminded of certain sprites and…

These not-even-wrong nonarguments are standard for the denier industry. No scientists predicted a monster El Nino. It was suggested it was a possibility, and all the heat in the oceans has to go somewhere, but a weak El Nino is consistent with the PDO in a negative phase (as it is).

It's also true that meat eaters are just as irrational.

If you believe that, then you don't understand even the first thing about climate modelling. Predicting an El Nino is not the same as projecting global warming and some of its effects on the climate.

As I tried to allude, and will now make explicit, that is not the point. The point is whether or not it is sustainable for 7.3 going on 8 going on 10 billion humans to be eating meat, especially when it's not necessary . The answer to this is a clear "no".

I'm saying the US is a considerable part of the problem. Of the large developed countries, with substantial populations, the US remains the worst in terms of per capita emissions. Many of those emissions are hidden by the offshoring of manufacturing, which doesn't show up in the baseline figures (a problem also faced…

US only. :(

1) Not nearly enough, in either case.

Okay.

You are missing the point. GPS was never intended to track anyone, I agree. The software that allows you to use it is a different matter. In order to use most GPS functions in, for example, Google's software (typically turned on by default), you have to allow it to report your location, or at least allow Google to…
