IT IS depressing to read misleading claims about climate change and the proposed Adani mine (Norma Lawrence and David Stark, Friday, August 31). Yes, carbon dioxide is essential for plant growth and putting more into the atmosphere will be good for some plants, but it will also be bad for civilisation.
There is no serious doubt that climate change is being caused by the increasing amounts of greenhouse gases. The alternative theories cited by David Stark were discredited decades ago. Yes, there have been times in the Earth’s history when greenhouse gas levels were higher than they are today, but average temperatures were higher then and the sea level was tens of metres above where it is now. How could anyone living on the Coast want that sort of future? If we were really concerned about energy poverty in India, we would be helping villages to have clean solar or wind power. Many of those villages are not connected to any sort of distribution system, so they could not conceivably benefit from the misguided Adani project. Opening any new coal mine would be a decisive step in the wrong direction.
