SOME scientists believe that global warming is likely to trigger earthquakes, tsunamis, avalanches and volcanic eruptions.

They think climate change caused by rising outputs of carbon dioxide from vehicles, factories and power stations is very serious indeed. Already, glaciers are melting and, basically, we are all doomed.

Other experts are reluctant to blame mankind and suggest that these developments are a natural phenomenon.

We might still be going the way of the dinosaurs eventually, but it is not necessarily our fault.

I have heard a number of people recently putting forward the latter view. I simply do not know which school of thought is correct, none of us do, but I tend to think the first theory is more likely to be right.

Having said that, I have to ask myself if I am doing enough to prevent rising seas at Blackpool from inundating Bolton and other North West towns.

A current 10:10 campaign urges UK people and businesses to make individual efforts to cut carbon emissions by 10 per cent during 2010.

Thousands of people, including a sprinkling of celebrities, have signed up to do their bit to save the planet. This involves commitments to do such things as reducing the number of flights, turning down the central heating, wearing jumpers and learning to ride a bike.

This seems to be a popular grassroots movement and I am sure we will all hear more about it in the next few months.

Will it make any difference? I doubt it, but there is nothing wrong with a campaign that makes people feel better about themselves.

All will be justified, though, if we can stop just one polar bear from drifting on a melting iceberg into the Jumbles.
