I would totally agree with Carol Nixon, Penuwch, Tregaron, that it is important for the future of life as we know it that we get the facts correct (Letters, 23 January), and in helping to do so, I would recommend a very good book titled, Inconvenient Facts by Gregory Wrightstone.

Carol points out global warming has actually started and I have said as much in my letter that the Earth is warming through natural causes since the last Ice Age – sea levels have risen and continue to do so – there is tree stump evidence on the seabed in Cardigan Bay that certain areas were once dry land and not so long ago, so I guess we are in agreement here.

Although I disagree that all scientists say we are on a path to dangerous warming and there is too much CO2 in the atmosphere. I wonder if Carol realises that about 18,000 years ago the planet came dangerously close to losing all plant life, when CO2 levels approached 150 ppm - below which plant life cannot sustain photosynthesis and as such will perish.

The main driver of greenhouse warming is water vapour. Carbon emissions are a smoke screen (excuse the pun), a con, and the real danger that threatens mankind, is that of overpopulation.

This real threat manifests itself in the destruction of the Amazonian rainforest, and other forests, over-fishing of the oceans, pollution of rivers, lakes, seas and the atmosphere, the spread of disease, civil unrest, wars... the list is becoming endless!

To borrow Carol’s sentiment, it is very sad indeed that so many good people have been taken in concerning carbon dioxide and that a generation of children are being needlessly frightened out of their wits.
