I am an environmental engineer and have worked on behalf of the Environment Agency, the RSPB, English Heritage and many other environmental groups, I work with developers to reduce their impact on the environment. I have my own piece of land set aside as a nature reserve, I live on a large section and grow my own veggies, planted lots of trees around my section, work with the community to restore wetlands etc... I ride my bike or run to work when I can so you could call me somone who does his bit for the environment, however, when it comes to AGW I am a skeptic. I need proof before I worry about!
Co2 is not a pollutant and shouldnt be treated as such, it is of benefit to the environment. Instead of spending trillions trying to reduce a small fraction of co2 that will probably do litte and even potentially worsen a natural effect I think we should spend the money on cleaning up our rivers, improving farming practice, develop clean burning fuels, cheaper more effective solar panels for the third world etc...
And does anyone criticise the natural rotting of leaves or the sea for contributing 97% of atmospheric co2? No. What about the rise in greenhouse gasses not linked to humans? No they are ok to, just co2 is bad (0.054% of the greenhouse effect). Seems man made co2 is being targetted for a reason, whilst other greenhouse gasses are ignored, this is born from the IPCC's mission to prove a link between man made co2 and global warming.
I dont deny it could cause warming due to radiative forcing, but man made co2 is such a small part of the earths systems it lost within natural variability. Its like ignorning the engine or the electrics when your car breaks down and instead checking one of the wheel nuts on the rear right side wheel as Proffessor Tim Ball put it.
Where is the ozone layer depleting? The hole over the antarctic has almost completely healed since we cut back our use of CFC's (a good example of when a real problem exists we act quickly and concisivly to fix it), I am not aware of any new ones? This isnt linked to AGW either way.
