It means that if we overestimated the soil response to warming then we must have underestimated something else dramatically because we have a net effect of faster global warming.
Even if the law succeeds in reducing emissions as planned, however, it will have little practical effect on global warming.
In this audio section, BBC World Service environment specialist Richard Black explains the so-called greenhouse effect, global warming, the implications for the human race and the significance of the Kyoto summit.
Another example of his unorthodox thinking is his observation that painting the roofs of buildings around the world white and using light-coloured road surfaces rather than blacktop would reflect a lot of sunlight back into space possibly enough to have an effect on global warming as big as taking every car in the world off the road for a decade.
The main reason appears to be a catalytic warming effect, triggered by global warming.
"As each year passes and we hear that a warming record has been broken, or nearly broken again, it provides further evidence that unfortunately we are not just seeing a natural cycle of global warming, and that instead humans are having an effect on the climate, " said Dr Huntingford, who works with climate models to understand the implications of increased levels of greenhouse gases.

Since both of these chemicals are more potent greenhouse gases than carbon dioxide, this effect, too, should help combat global warming.
ECONOMIST: Biochar could enrich soils and cut greenhouse gases as well
If you believe that man-made gases are the cause of global warming, then address methane, which has a much more devastating effect than CO2.
Some of the warming is obviously the result of human activity, but our effect on the global climate remains unclear.
It said the gases had "very high global warming potentials compared to carbon dioxide", as an amount about 1g in weight could have the same effect as 1 ton of carbon dioxide being released into the atmosphere.
Dr Harries's conclusion is that the greenhouse effect has changed over the past few years in exactly the way that those who believe in global warming would have predicted.
But even wild-eyed global warming hysterics admit that strict CO2 emission restrictions in America alone are not going to have any more than a negligible effect on future global temperatures.
