2014 – The Hottest Year on Record

2014 was the warmest year since 1880, when scientists began recording temperature. This news comes from scientists at both NASA and NOAA. Each year they collect and analyze global surface temperature data. The long-term trends show that the Earth’s average surface temperature has risen by 1.4°F. In fact, the ten hottest years on record have occurred since 2000 with the exception of 1998.

Variations in temperature are likely to continue in the future based on El Niño or La Niña effects. But the overall trend of global warming will continue. Human activity is the main driver in this warming and scientists are presenting clear evidence of those facts. Without a significant push to reduce carbon emissions worldwide, we can expect record-breaking temperatures to become the new norm.

NASA has produced a video worth watching to see a time series of five-year global temperature averages, mapped from 1880 to 2014.
