Is that the right link? (assuming it remains available, I find it ever harder to remain informed on these matters)

Frankly I think if you expect a meaningful and productive response from governments (or people en masse) you are grossly misjudging human behaviour.

I listened to the video there, and for what it's worth I agree with John Nissen, assuming I correctly understood him to be saying that civilisation is on a path to absolute failure within the near future (coming years, not decades).

I do not agree that it is possible or probable that we can prevent this.

I also probably can't contribute to discussions in this group as I'm not a scientist and my focus is very much on that complete failure scenario (and has been for some years).

On that note, if anyone has anything to better help me understand the regional consequences of abrupt release of large volumes of methane I'd like to know. For example a few of my questions:
- is hydrogen sulphide a concern and if so, on what timescales and in what general regions?
- is methane outgassing likely to reach levels where it can form large scale explosive mixtures with the atmosphere?
- if hydrogen sulphide is produced, is there a risk to the ozone layer and over what timescale?

I appreciate it's a long shot, since established science seemed to be saying only a few years ago that the sea ice would last until the end of the century...

I went. Lenton and Wadhams gave evidence, as well as Nissen. It was surprisingly moderate.

The MPs seemed semi-well-informed, but seemingly more concerned with decadal effects than serious long term problems.

Zak Goldsmith was very anti, seeming not to recognise fully the dangers of warming.

Frighteningly, the MPs even asked whether arctic sea ice loss was really happening. They seemed surprised that all the witnesses agreed it was, and would have serious consequences for the climate. Seemingly Deniers are more influential than we like to believe.

If anyone finds a link, please post it.

This letter is heartening to see, as many of us are very uncomfortable
with the notion of near-term deployment in the Arctic.  Did anyone
attend this hearing?  I know John Nissen was scheduled to be a
witness.  Is this available for viewing online?
