Climate Change Again

I regret to say this but the message about man made climate change is not getting through. I recently had a conversation with a gentleman in a restaurant who simply did not believe that mankind could have any effect on the environment let alone an adverse one. He believed that nature was much more powerful than mankind that that the rise in the temperatures and increase in the concentration of carbon dioxide in the air was all caused by nature. Of course he was correct that the rest of nature is and always will be more powerful than mankind. We are after all part of a whole. He could not accept my argument that the present composition of the atmosphere was substantially altered in pre-cambrian times when cyano-bacteria produced substantial quantities of oxygen which lead the way to the rapid increase in oxygen breathing animals and plants on the the earth. He also did not believe that the during the carboniferous period the earth's atmosphere was also altered by substantial plant growth to produce an atmosphere which had a concentration of oxygen much higher than today. It was, as if, he believed there was a disconnection between the activities of plants and animals and the geological conditions of the planet. He also felt that there was a complete disconnection between mankind and other forms of animals and plants and that none of our activities could affect nature. When I put forward the view that the rest of nature had taken millions of years to affect the composition of the atmosphere but that man himself had suddenly, and in the course of a couple of hundred years, increased the level of carbon dioxide to dangerous levels he was non-plussed. He would not concede that we were upsetting the equilibrium of the atmosphere such that we are about to arrive at a tipping point and set in motion dangerous climate change. The message had not got through despite all of the publicity and documentaries on television about climate change. Amongst most of my friends, there is still doubt or mild scepticism about man made climate change and the message has not got through to them. These attitudes are probably dangerous and the future health of the human species will be put into jeopardy if there is not a change of opinion. There are plenty of documentaries on television which are explaining the science but of course they have to compete with the X-Factor. My colleague in the restaurant was right as nature is more powerful than us but we are not supernatural beings which are immune to the influence of nature. If we trigger off dangerous "natural" climate change will will suffer along with many other species. Nature does not care about us and will be immune to our suffering. Life will prevail on the planet for many millions of years longer but it us up to us, as well as nature, to decide whether we shall be part of that survival or not. The choice is ours: is it X-factor or science?
