The world’s leading climate scientists have (very) slightly differing perspectives.

Each year, NASA Goddard (US), the Met Office Hadley Centre (UK), NOAA  National Climatic Data Center (US), and the Japanese Meteorological Agency pool their collected temperature data, from sources across the globe, presenting their independent observations about the year previous.

While minor variations due occur from year to year, each data set, visualized at right, offered peaks and valleys that are strikingly similar to each other. All data sets seem to agree that the ten warmest years in the 132-year record have happened since 1998.

Trends like these are difficult, if not impossible, to ignore. All the data seems to demonstrate a long-term rise in global temperature data.

‘The average temperature in 2012 was about 14.6 degrees Celsius (58.3 degrees Fahrenheit), which is 0.55°C (1.0°F) warmer than the mid-20th century base period. The average global temperature has increased 0.8°C (1.4°F) since 1880, and most of that change has occurred in the past four decades,’ said Goddard Climatologist Gavin Schmidt.
