NASA isn't the only climate-watcher warning us that our planet is warming up. The Japan Meteorological Agency (JMA) has release data showing that the spring of 2014 was the warmest since records began 123 years ago in 1891.
After crunching the data, JMA found that the seasonal anomaly of the global average surface temperature in March to May 2014 was +0.28°C above the 1981-2010 average and +0.69°C above the 20th century average. On a longer time scale, global average surface temperatures have risen at a rate of about 0.75°C per century. A single celsius might not seem like much until you stop to think about how much energy it takes to warm up the whole Earth's atmosphere and oceans.
Here's the spring of 2014:
North America was lucky during the period, staying relatively cooler than the rest of the world, but as we often repeat, what matters is the global climate, not the local weather:
The month of May 2014 (the latest for which full data is available) was also record-breaking, with the hottest temperatures since records began in 1891.
