Europe Is Warmer Than Canada Because of the Gulf Stream, Right? Not So Fast
The common tale—the one bandied around for more than a hundred years—goes something like this: Warm water flowing to the northeast out of the Gulf of Mexico—the Gulf Stream—cuts across the North Atlantic ocean, bringing extra energy to the Isles and driving up temperatures relative to the comparatively-frigid North Americas. The only problem with this simple explanation, say Stephen Riser and Susan Lozier in Scientific American, is that it doesn’t actually account for the difference.

Beatiful dataviz of weather data from met.no, NOAA.gov, World Weather Online and Weather Central. The main graph includes: mean and percentiles of historical temperature data for time of year, the temperature and precipitation forecast over the chosen period, wind direction and speed, with hourly data. Very nicely done! (via Una Mullally)
