ALTHOUGH Walter Attwood’s heart may be in the right place regarding man-made climate changes, the scientific basis of his arguments holds little water (Letters, March 19)..

As a proportion of the global production of carbon dioxide (CO2), the UK’s contribution is negligible at 1.3 per cent (Scotland: 0.13%).

Moreover, since the estimated proportion of CO2 which is man made is less than 5% of the total, any attempt to reduce the risk of adverse climate changes, even by completely ending our home, industrial and transport activities, would be hopeless, a “fool’s errand” indeed.

Therefore, the billions of pounds spent on curbing CO2 output (last year, £8.6bn), the costs of and damages by “renewables,” the closing down of fossil fuelled power production and the school childrens’ demonstrations and strikes are all going to utter waste.

The Climate Change Acts (2008 and 9) must, logically be repealed.

In freeing up the vast monies these cost, great national benefits could accrue.
