The quote has been taken out of context. It relates to our ability to track energy flow through the climate system. We can do this very well from 1992 to 2003, when large warming occurred, but not from 2004 to 2008. The quote refers to our observation system which is inadequate to observe Earth's energy flows at the accuracy needed to understand small fluctuations in climate; it does not mean there is no global warming, as is often interpreted by the likes of Danaher. What is does mean is that our observing system is not adequate to fully track the energy in ways that allow us to understand and make best statements about the effects of natural climate variability: the La Niña of 2007-2008, and the current El Niño, for instance.
... But global warming does not stop weather from happening, and cold outbreaks continue and are fully expected. It does not stop winter. And it does not stop La Niña from happening and setting up unusually cold regional patterns of weather across the United States and other parts of the world that last a year or two.
To misunderstand the role of weather and natural climate variability the way it is being done is to undermine much-needed actions in limiting carbon dioxide emissions. Global warming is happening. It will continue to happen and the way we are going it will jeopardize the very nature of climate on planet Earth some decades from now. Because of the long lifetime of carbon dioxide, by the time it is so obvious to everyone, it will be far too late to do anything about it.
