2010 går inn i bøkene som det våteste året man har målt, på verdensbasis. I tillegg det varmeste året siden man har sammenligningsgrunnlag (1880), sammen med 2005.
Combined global land and ocean annual surface temperatures for 2010 tied with 2005 as the warmest such period on record at 1.12 F (0.62 C) above the 20th century average. The range of confidence (to the 95 percent level) associated with the combined surface temperature is +/- 0.13 F (+/- 0.07 C).*
The global land surface temperatures for 2010 were tied for the second warmest on record at 1.73 F (0.96 C) above the 20th century average. The range of confidence associated with the land surface temperature is +/- 0.20 F (+/- 0.11 C).
Global ocean surface temperatures for 2010 tied with 2005 as the third warmest on record, at 0.88 F (0.49 C) above the 20th century average. The range of confidence associated with the ocean surface temperature is +/- 0.11 F (+/- 0.06 C).
In 2010 there was a dramatic shift in the El Niño-Southern Oscillation (ENSO), which influences global temperature and precipitation patterns when a moderate-to-strong El Niño transitioned to La Niña conditions by July. At the end of November, La Niña was moderate-to-strong.
According to the Global Historical Climatology Network, 2010 was the wettest year on record, in terms of global average precipitation. As with any year, precipitation patterns were highly variable from region to region.
The 2010 Pacific hurricane season had seven named storms and three hurricanes, the fewest on record since the mid-1960s when scientists started using satellite observations. By contrast, the Atlantic season was extremely active, with 19 named storms and 12 hurricanes. The year tied for third- and second-most storms and hurricanes on record, respectively.
