NOTE ON POPULAR POSTS

The reason some popular posts are tagged ‘no title’ is not because they have no title—they all do—but because the old Blogger embedded the title at the top of text, and the new software does not see that. You can see the titles in capitals at the start of each snippet. (It would be nice if Blogger introduced an upgrade program that could fix this little problem.)

FAST TRACK TO AN OVERHEATED EARTH

An article on BBC News implies an interesting question. A study has shown that at the present rate we will have pumped as much greenhouse gas into the atmosphere in 300 years as was pumped over 10,000 years 55 million years ago. At that time a 5-degree (Celsius) rise in global temperature was the result. But that is about the rise predicted by optimistic modelling for this century alone. Which suggests that we must take into account not only the amount of greenhouse gas going into the atmosphere but also the speed at which it goes. In other word, the rate of addition has an accelerating effect of its own. A slow addition can be accommodated in a way that a fast one cannot.

In short, we are for it. The worst scenario is what we are going to get.
