The National Oceanic and Atmospheric Administration says last month was the warmest January on record. That sets off alarm bells for climate scientists, but for the average person living in a northern climate, it might not sound so bad.
That's what many people are saying these days in Russia, where the expected icy winter has failed to materialize this year – to widespread joy. Of course, any climate scientist will tell you that an unusually warm month — or even a whole warm winter — doesn't mean much. It's the long-term trend that counts.
