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.
