1st Dec 2008 : The first 700 million years of Earth’s 4.5-billion-year existence are known as the Hadean period, after Hades, or, to shed the ancient Greek name, Hell.

21st Feb 2008 : A guide at the Natural History Museum stated confidently that a particular dinosaur was 70,000,008 years old. When asked how he could be so precise he replied, "Well it was 70 million when I started this job, and that was eight years ago." The evident experience of Valentina Cruz, our wonderful Galapagos naturalist guide, suggests that I must add a similar margin to the estimate of 100 years that she gave us for the age of the black lava fields on the island of Santiago. The exact date of the great Santiago eruption is not recorded, but it definitely happened on one particular day in one particular year around 1900. I shall call it SV day (Santiago volcano day). I need to seem as precise as the museum guide, although the exact date doesn't matter. Perhaps it was January 19 1897, 100 plus eight years before my visit to the island.

20th Nov 2007 : In casting my mind around for a subject for a blessay (blog + essay) I have come up with one that was forced to my attention the other night when I participated in a regrettable and unhappy verbal spat with an American gentleman. I shan't give details about him, it wouldn't be fair, so let's call him Jim and leave his statehood, profession and other details unventilated. I will try and be as fair to him and as scrupulously honest about myself as I can be. It was an upsetting evening and I wish it hadn't happened, but I suspect evenings like it are taking place everywhere around the planet.

12th Mar 2007 : The harmful effects of global warming on daily life are already showing up, and within a couple of decades hundreds of millions of people will not have enough water, top scientists are likely to say next month at a meeting in Belgium.

8th Mar 2007 : Is the Earth sphericated or flaticular?

6th Feb 2007 : Carbon dioxide, a greenhouse gas that has become a bane of modern society, may have saved Earth from freezing over early in the planet's history, according to the first detailed laboratory analysis of the world's oldest sedimentary rocks.

15th Jan 2007 : The school board in this suburb south of Seattle has restricted showings of Al Gore's movie on global warming, including requiring that it be balanced with an adequate opposing viewpoint.

12th Jan 2007 : This week in Federal Way schools, it got a lot more inconvenient to show one of the top-grossing documentaries in U.S. history, the global-warming alert "An Inconvenient Truth."
