NASA's recent GISTEMP update (Goddard Institute for Space Studies Surface Temperature Analysis) update is, to say the least, an interesting one. Here are the highlights.
The analysis by NASA shows that September 2016 was the warmest September in 136 years of modern record-keeping by a very narrow 0.004 degrees Celsius over the previous warmest September which occurred in 2014. This means that 11 of the past 12 months have set new monthly high-temperature records.
Here is an interesting graphic showing seasonal temperatures with older years in blue and newer years in red:
The data used in the analysis is acquired from 6300 worldwide meteorological stations as well as instruments aboard ships and bouys and from Antarctic research stations. Modern global temperature recordings began around 1880; prior to that, observations did not cover all of the globe.
Here is a graphic showing the land-ocean temperature index (LOTI) anomaly for the month of September:
Most of September's warmer temperatures occurred in the northern hemisphere.
While there are strong emotions for both sides of the climate change discussion, there is one question that has to be asked, "What if climate scientists are right?".
