Stellar thinking from mental giant David Attenborough: Whether CO2 is overheating the planet or not, we can still prevent planetary overheating by tweaking CO2

Lord Lawson accuses Sir David Attenborough of ‘sensationalism’ - Telegraph

In the final episode of the popular series, which will be broadcast on BBC One on December 7th, Sir David claims that the Arctic could be ice free in summer by 2020 and polar bears are already dying due to a lack of ice.

...“I don’t think anyone can seriously deny it is happening,” he said. “What the controversy is about is whether mankind has been a factor in that. I personally think we have and it would be surprising if we hadn’t given what we have been doing for the last 125 years. But in the way it is irrelevant given temperatures are increasing and we know that is potentially doing a lot of damage and if we can we should try and stop that happening. Whether it is caused by us or not, we can bring down carbon emissions and that could stop temperatures rising.””
