Climate change, global warming and environmental Issues are, quite rightly, often in the news. I, for one, am more than pleased with the great focus on these subjects nowadays although there are many influential people and organisations that, despite scientific evidence, continue to deny the facts.

The stamp depicted on the left was issued by Ascension Island in 1979 to commemorate the 200th anniversary of the death of the great British explorer, cartographer, navigator and Royal Navy Captain, James Cook.
