and that's exactly the point: we should focus on whether or not you got any money from coal, regardless of what you did with it, because that's what is driving emissions in the end.

Quite interesting remark. However, I'm not saying the savings from producing more wind are not real. They are very real, because you avoided using other means of production, potentially fossil fuels. So that's good.

On the other hand, saying that you basically got your Macbook for free (saved all the money, i.e. ran exclusively on wind) can only work if you didn't spend anything else. Saving 999$ but spending 200 more (i.e. also having coal) and not counting it because you somehow earned more money somewhere else (i.e. exported it) is not what I call proper bookkeeping.

We're tracking live electricity generation from solar in the US here: https://www.electricitymap.org Not sure we will be able to see the effect talked about here though.

sorry for not being clear enough. I meant that the speed of warming is of interest here. That speed is independent of the baseline chosen. And that speed is what is worrying.

We'd be incredibly unlucky to have missed a temperature change as fast as the one we're measuring now, if it indeed would have been caused by a small sample size of past measurements.

Take the reference that is 5min ago, call it T0. You will still observe that temperatures (i.e the sequence of measured temperatures minus T0) are increasing. Changing the reference changes the y-scale of a graph, but does not change the derivative (the speed at which it changes, i.e. increases or decreases).

You're right. However, it's hard to argue with the speed at which this warming occurs. It's never seen before if you look at all the records we have. That's what's worrying.

You shouldn't care about what reference is taken. The point is that compared to any reference, the curve is increasing.

The easiest fix to the intermittency problem is to use electricity when renewables produce [1]. That would reduce the need for batteries in the beginning.

We're looking to expand http://www.electricitymap.org to the US in order to properly visualise this. Can anyone help? I'm looking for volunteers to help here: https://github.com/corradio/electricitymap/issues/143

Hi there,

I'm the author of the map. For sure it can be optimised. If you can help, feel free to do so on github - or reach out so we can chat. Thanks :)

I actually made a small script to download offline youtube videos using youtube-dl.

Would like to know where to get those $2 magnetic probes :o
