So which term is it?

So which term is it?

So often we hear of Global Warming. But then we also hear about Climate Change. And then just to confuse things even further we hear about the Greenhouse Effect.

The fact is these are three separate and distinct concepts that have lately been linked together to pretty much equate to the same thing - the idea that man made activity is forcing disastrous effects on the world around us.

Now if there were ever an example of hedging your bets in an argument this is it. And it’s so easily done: First of all invent the threat of a climatic scenario - global warming and feed it with inflated, distorted, and highly selective examples that to the average person without any specialised knowledge may seem quite plausible. Then just to feel doubly secure introduce a second catch all situation - Climate Change - that could comfortably account for any freak of nature of the sort that have been happening for thousands of years.

By now you have the recipe for turning virtually any weather anomaly into indisputable proof of a catastrophic situation that needs quite urgent attention.

But where did all this start off at? Ah yes! It was the Greenhouse Effect. Funny thing is that you don’t hear so much about this just now. Global warming yes! Climate Change yes! But the Greenhouse Effect no! But why? After all, this was where all this hysteria got going with the idea that Greenhouse Gases were trapping heat in the atmosphere that couldn’t escape into space. Trouble is that for this to be happening there would have to be a sort of uniform heat effect across the whole of the globe. It means that no matter where the winds blew from they would always be warm. Yet as everyone knows, and as the maps included in this site illustrate, the world is still capable of quite extreme changes of temperature often within a very short time: A fact that would simply be impossible if true global warming were indeed responsible. That’s why the term Greenhouse Effect has now been ditched in favour of Climate Change.

As for Global Warming, this too is a term that is gradually becoming less common as the evidence throws up glaring inconsistencies that show that as some places have warmed up others have cooled down, or remain unchanged, and that taken as a whole, average temperatures for the planet have shown little variation for a very long time. In other words no great problem, and certainly not one that requires the mobilisation of effort to solve a crisis that never existed in the first place.
