Carbon dating real fake
But by 2003 new data came in and it was clear that . Temperatures appear to control carbon, and while it’s possible that carbon also influences temperature these ice cores don’t show much evidence of that.
Some commentators, including the GWPF, adopt a so-called ‘lukewarmist’ position, arguing that climate change will not be too bad so there is no need to stop using fossil fuels.As Nasa puts it: “There is no question that increased levels of greenhouse gases must cause the Earth to warm in response.” All this does not scientifically prove beyond all doubt that our greenhouse gases, which also include water vapour, nitrous oxide, ozone and methane, are causing global warming.But the correlation between the two and the evidence of causation first supplied by Tyndall make a compelling argument.Carbon may still influence temperatures, but these ice cores are neutral on that. Some other factor is more important than carbon dioxide, or carbon’s role is minor.If both factors caused each other to rise significantly, positive feedback would become exponential.

Svalbard in the Arctic has seen average winter temperatures rise by up to a staggering 11C compared to the average between 19.
In the 1990′s the classic Vostok ice core graph showed temperature and carbon in lock step moving at the same time.
It made sense to worry that carbon dioxide did influence temperature.
What follows is the complete set from 420,000 years to 5,000 years before the present.
The bottom line is that rising temperatures cause carbon levels to rise.
But the idea remained mostly an academic question until, as he predicted, the mercury started to rise.
