NASA released their global climate summary today, and it shows that according to their calculations, January 2017 was the third warmest in 137 based on modern record-keeping. Last year was the warmest, followed by 2007. Note that as expected, most of the warming is occurring at higher latitudes due in part to snow and sea ice albedo feedbacks. NOAA will be releasing their summary tomorrow and it will be interesting to compare the two. You can read the NASA news release at https://data.giss.nasa.gov/gistemp/news/20170215/.
