Climate change week 2

Well I got 13 out of 15 for the final test this week, so I must be doing something right? ( I think they went easy on us; the course is realy hard) “The idea of a ‘tipping point’ was an important one this week in that, while the different feedback mechanisms can balance the levels of greenhouse gases and the heating/cooling effect, there is a point after which the result is inevitable. Having reached a snowball earth it required volcanic eruptions to re-introduce the greenhouse gas ‘blanket’ to break the hold.” (quote from a fellow student) We are going the other way now and will surely need a ‘tipping point’ event to push us back to a normal balance.

More mental struggle next week.

I am in my seventies and live in the west coast of Scotland, with the sea at the bottom of my garden. I have been variously, a sculptor an art teacher, designer, inventor, organic grower and last but never least, a blue water sailor. By the way, I have been telling stories and writing nonsense all my life!
