We must have all experienced it. That feeling that you’ve been somewhere before when the fact of the matter is that you haven’t.

Déjà vu. Recently, scientists have been trying to study the phenomenon. But because the experience is such a fleeting one and you can’t tell when it’s going to happen it’s very difficult to measure.

Apparently there are some chronic sufferers and it affects their everyday lives. But it’s still almost impossible to study those people. A professor at a clinic rang up a patient of his who suffers from chronic déjà vu to ask him to come in so he could run some tests. But the patient refused to on the basis that he’d been there before. I suppose we’ll never know then.

Hang on, haven’t I told you this before?

I guess we all have a responsibility when it comes to global warming. I suspect all of us think about recycling even if we don’t do it religiously.

We’re constantly being told that the ice caps are melting, sea levels are rising (although we’re about to experience a water shortage…..!). Apparently we’re on the edge of catastrophe and past the point of no return.

It’s all down to us and our careless use of fossil fuels and electricity. Which is why it is important that we can predict what will happen to the weather in years to come.

A project has just been launched that will enable us to do just that. The more people that take part the more accurate the results will be. All we have to do is switch on our computers and run a programme that examines millions of climate models and predicts what is most likely to happen.

Just think of all the electricity it will use.
