When I first started high school in very late 70s it was predicted by many scientists that we were heading for another ice age. Then it somehow changed in the 1980s, and it was global warming not another ice age. Now it's another ice age again.
Wasn't there a Discovery channel documentary on a couple of years ago examining this, with some scientists on there believing that this was all part of a natural cycle and the next few years would be harsh winters, before warming again.
More recently we had another documentary (was it Channel 4 this time, can't remember?), but again it had some scientists saying the same while others were sticking to the global warming theory.
Of course, just calling it climate change gets them off the hook somewhat, as it doesn't matter whether it gets hotter or colder, they can still say "See, told you so!"
Or, alternatively, it's because science progresses and new ideas are formed with old mistakes gradually corrected.
Climate change= money,money and more money as we are too stupid to think for ourselves apparently.
We are just returning to the weather of the 70s and 80s.
yep - i think its just part of a cycle. I remember nearly all winters being like this in the late 70's and early 80's. Bonfire night on Nov 5th always used to be freezing cold, and walking to school nearly always with snow and ice on the ground - but then it all got warmer. Its just going back to how it was before.

No, it was not. Most papers on the subject in the 70's were predicting warming in the decades to come - but with an acknowledgement that the science was too uncertain to be able to make confident predictions.

What happened is that the science predicting warming became more certain, and the temporary cooling trend that had prevailed since the 1940s came to an end. Nobody credible is predicting another ice age (or more correctly, the end of the current inter-glacial).

The Great Global Warming Swindle? Hopeless, lying piece of crap from start to end.

Not really. The planet as a whole has to get hotter, or the theory is wrong. That doesn't mean each year has to be hotter than the previous one. And the consequences for regional climates are complex and not fully understood. There may be surprises ahead. As Wally Broeker put it: "Climate is an ill-tempered beast, and we are poking it with sticks"
As far as short-term fluctuations are concerned, it's a zero-sum game. If we're getting colder, it's because somewhere else is getting hotter.
Well as we are seeing all those clever people who predicted warming forgot that the globe has a built in mechanism for dissipating the extra energy absorbed due to the greenhouse effect which means that the computer predictions are'nt accurate & we are seeing colder winters in the northern hemisphere & we seem to get arctic winds much more often in the last few years. So for us in Britain climate change seems to mean hotter summers with some prolonged dry times & localised heavy rain causing floods & prolonged cold spells in the winter.
How far will these effects go is the $6million question?

Are you admitting that you want to wallow in your ignorance and are not bothered about being enlightened?
Amazing.

We have to hope that the current winter is more the exception than the norm.
Worryingly, scientist think it possible have already passed the West Antartica tipping point.

So far more likely , 'you reaaly ain't seen nothing yet!'
