You can't make it up XXXIII - BBC admits there has been no warming for 15 years (21 may 13)
If there had been continuous warming since 1998, the proponents of the theory of anthropogenic global warming would seize on it. But in fact, as even the most servile of their media lackeys report, there has been no world temperature rise for fifteen years:
"Since 1998, there has been an unexplained 'standstill' in the heating of the Earth's atmosphere".
"Unexplained". The theory does not explain the facts. It doesn't predict the facts. It predicts the opposite.
So... do they use the reality to attempt to falsify their theory? They do not. It's not science.
