Fulfilling most meteorologists expectations, 2014 has been officially proclaimed the hottest year in recorded history.
The announcement was made on Monday by the Japan Meteorological Agency, one of the four most trusted entities on global weather measurements. The remaining three – NASA, the National Oceanic and Atmospheric Administration (NOAA) and the Hadley Center – are expected to release their data in the next few weeks. Though all four will likely publish slightly varying datasets, the consensus will likely support 2014 as the year with the highest average global temperature.

According to JMA, the average global temperatures were 1.1°F above the 20th century average in 2014. That beats the previous record-holder, 1998, by 0.1°F.
The announcement by JMA follows a year of record-setting monthly temperatures on land, record-setting monthly temperatures for the ocean and the single hottest year in California’s history. Further, three independent teams of scientists recently declared that 2014 boasted the highest temperatures in Europe in over 500 years, a state that was 35 to 80 times more possible by the man-made increase of greenhouse gases.
Speaking of greenhouse gases, 2014 actually topped 2013 for greenhouse gas emissions. In September, Planet Experts reported that more carbon was pumped into the Earth’s atmosphere in 2013 than ever before. Early reports for last year put global carbon dioxide emissions at 44 billion tons, a 2.5 percent growth over 2013.
Warmer-than-average temperatures were experienced in Europe, Africa, Australia, South America, the Caribbean, east Asia, the Arctic and western North America. Central Asia and the eastern United States, however, experienced colder-than-average temperatures, likely due to the polar vortex effect.
Of course that did not stop climate deniers in the eastern U.S. from poo-pooing global warming altogether.
