CO2 levels are not at unprecedented highs.Today, about 0.038 per cent of the atmosphere consists of carbon dioxide, the main man-made climate change gas. This figure has certainly risen over the past 200 years or so - the 'pre-industrial' level of CO2 was closer to 0.02 per cent. But what is often ignored is that in the Earth's past, carbon dioxide levels have often been as much as ten times higher than they are today. For example, during the Cretaceous era, when dinosaurs ruled the Earth, CO2 levels were five to ten times what they are today. The planet was certainly warmer then, but life thrived and there was no runaway greenhouse catastrophe of the sort that the doom-mongers insist we face if we let levels rise further. They also, it should be noted, came down again naturally.
Perhaps now we can sack all the busybodies in national and local government that want us(not them) to live in the stone age.
