Reuters gets it wrong again: If Chinese emissions have been higher than assumed then emissions have even less effect on climate than thought!

Reuters reports that Chinese carbon dioxide emissions may be some 20% higher than previously thought. But then the Reuters reporters (David Fogarty¬†and David Stanway) and their editor Jonathan Thatcher get their knickers properly in a twist and conclude that this suggests that “the pace of global climate change could be even faster than currently predicted”.

Perhaps some bright schoolboy could point out to our intrepid reporters that if the change in B is supposed to be dependent upon the change in A and if the change in A is actually higher than assumed, then the change in B is less dependent upon the change in A than assumed.

What the reporters probably mean is that the computer models which assume the dependence upon emissions will now show more warming – and will be even more in error than they already are.

China’s carbon emissions could be nearly 20 percent higher than previously thought, a new analysis of official Chinese data showed on Sunday, suggesting the pace of global climate change could be even faster than currently predicted.

China¬†has already overtaken the United States as the world’s top greenhouse gas polluter, producing about a quarter of mankind’s carbon pollution that scientists say is heating up the planet and triggering more extreme weather.

But pinning down an accurate total for China’s carbon emissions has long been a challenge because of doubts about the quality of its official energy use data.

It is that data which is used to compute how the planet’s climate will change, helping plan for more extremes of drought, flood and the impact on crops.

“The sad fact is that Chinese energy and emission data as primary input to the models will add extra uncertainty in modelling simulations of predicting future climatic change,” say the authors of a study in the journal Nature Climate Change.
