Watch the world get progressively warmer over 130 years (Credit: NASA)

The year 2013, if you choose to believe the rigorous data released yesterday by the National Oceanic and Atmospheric Administration, tied for the fourth-warmest on record. Although, if you listen to NASA instead, it was actually the seventh-hottest. Its precise ranking — influenced by differences in data processing — isn’t very important. When it comes down to it, both agencies are saying the same thing: Last year was unusually hot — one of the hottest since 1880 — and it followed a pattern in which unusually hot years are becoming the new normal.



Be it a polar vortex or a record-breaking heat wave, it’s not one unusual weather pattern we need to look at — it’s the progression of things getting more and more unusual over time. An animation of temperature anomalies over 130¬†years, provided by NASA, shows how that’s indisputably been the case. Note the growing number of red-colored zones where temperatures were warmer than average, which take over the map as time goes on. This is what scientists say when they emphasize the importance of long-term climate trends:
