I’ve written a number of blogs now where I try to get to grips
with some of the numbers underlying global warming. So far, I
agree that the historic figures do demonstrate global warming
over the last 100+ years within a relatively wide band of
possible growth rates, and that the evidence shows that the
levels of carbon dioxide have increased since about 1950.
Furthermore, the science behind the link between carbon dioxide,
methane and the greenhouse effect (and so global warming) is
simple science that has been known for many years; in fact,
global warming/the greenhouse effect is science that enables
life on earth as without it our planet would have an
inhospitable temperature closer to -18oC, i.e. it heats up the
earth by about 33oC already to 15oC. What interests me next is
how have temperatures and greenhouse gases moved in the past? I
will try and analyse this by looking at some neat science that
analyses climate data over a longer period. This will get to the
nub of the issue, i.e. what is driving glob
