Last year, 2014, was the hottest year ever recorded on this planet. January 2015 continued the trend, ranking as the second-warmest January on record.
According to a report released by NOAA’s National Climatic Data Center, Earth’s combined average temperature for the month – over both land and sea surfaces – was 54.99°F. That is 1.39°F above the 20th century average. The warmest January on record occurred in 2007, when the temperature was 1.55°F above the long-term norm.
While heat dominated most of the planet last month, some places were particularly warm. China had its warmest January on record since 1961. In the contiguous US, seven western states – California, Idaho, Nevada, Oregon, Utah, Washington, and Wyoming – each experienced a January rated in their top ten warmest.
Global climate records go back to 1880.
