Don’t believe that the globe is warming up ? Not even after scanning the available sources ? Well, that’s probably down to the failure of your public and private Media, who are, for the most part, seemingly institutionally incapable of telling the full unexpurgated facts :-
“19 June 2010 : Contrary to the impression you might have gained from the media, the global climate is NOT cooling. In fact, the last twelve months, June 2009 – May 2010, has been the hottest June-May period on record, in both the 31-year satellite record of lower atmosphere global temperature and the 131-year surface global temperature record. In both data series the last 12 months have been more than 0.4C hotter than the average temperature of the last two decades of the 20th century…”
And why just stop at the evidence from the temperatures ? Don’t believe the oceans are deteriorating ? Why not look at the full range of research ?

Imagine, if you will, that we can peer deep into a solid object, and looking very, very closely, smaller than the eye can actually see, we can begin to make out the internal structure of that object, and zooming even closer in, we find what appear to be the smallest things that make up this object.
Let’s call these things ATOMS.
That’s a bit of Ancient Greek (or Jain) philosophy, the theory of the atomisation of matter, the idea that there are small things that make up large things, and that these small things cannot be made any smaller. This is a fantastic theory, as it explains a lot of things that happen around us. In several thousand years, nobody has seriously been able to challenge this theory; however, it has undergone continuous refinement.
Besides ordinary solid objects there are also things that you can’t hold in your hands; things like light and heat and the little electric shocks you get when you comb really dry hair.
Heat appears to be what happens to ordinary solid objects when the tiny atomic parts are moving wider or further or faster. Most things expand but stay holding together when they get hotter, which confirms this idea. There are special cases, like water, which expands as it freezes, but that can be explained by thinking about how atoms move in relation to each other…
Anyway, back to light.
Light is a different matter altogether. It appears to be able to pass through some objects without changing radically. It travels very long distances without being stopped. It seems to cause ordinary matter to heat up. It doesn’t rest anywhere.
