when we get record cold (which some areas got last winter), and "deniers" use that as evidence that global warming is a sham, what do you say to them?
Any recent cold records were records at that particular station. This is a record for the entire eastern hemisphere. It's quite a difference.
Also, if people are using the temperature at one station at one particular time to dismiss the trend over the last few decades they are probably not the brightest bulbs.
