NO ONE can say for certain whether human activity will result in climate change or not.

However, there are three facts I know to be true, because I can prove them, personally.

Firstly, the concentration of carbon dioxide in the atmosphere is increasing.

Secondly, human activity is adding billions of tonnes of CO2 to the atmosphere every year. This CO2 had, previously, been locked in the earth for millions of years.

Lastly, CO2 is a greenhouse gas.

If we do nothing and these facts result in the predicted climate change, what sort of legacy are we leaving for our children and grandchildren? Are those who deny the connection prepared to take that risk?

AS SOMEONE who has supported the Bluebird Project at both the Ruskin Museum, Coniston, and the rebuild project for many years - having raised money by giving talks about Bluebird and Donald Campbell to many organisations - can I, through your newspaper, ask this question of all parties?

What do I say to future audiences that I visit when I am asked how much of a donation they should give, and what are they giving it for?

I thought we were all volunteers working for the same cause in order to bring Bluebird back to Coniston. I am not sure that I can in future ask people to give to continued confrontation.
