This appears to be good news because it means that man made global warming may not lead to more frequent occasional extremely cold winters after all.

However, it says:
"..Temperature extremes will therefore become rarer as this variability is reduced. But this does not mean there will be no temperature extremes in the future. "Despite lower temperature variance, there will be more extreme warm periods in the future because the Earth is warming," says Schneider. The researchers limited their work to temperature trends. Other extreme events, such as storms with heavy rain or snowfall, can still become more common as the climate warms, as other studies have shown.

+ there is the big thorny issue of sea level rise. So we still have got a big problem.
