Seems like that every day some warmer announces that 2015 was the hottest year on record. One wants to ask, “what record” are you taking about? Reconstructed temperatures for thousands if not millions of years suggest that there are many periods that have had higher temperatures that those we are experiencing today. For those years which we have reasonably accurate temperature measuring devices they would suggest that 2015 was likely not the hottest although it might be among the hottest. Of course there is the problem of “man-made” warming as discussed in this posting “ This Is “Man-Made” Global Warming Courtesy Of NASA”.
To give another perspective on this issue, let us use the recent posting by James Delingpole “No, 2015 Was Not The Hottest Year Evah…”. Delingpole has a really sharp wit. He uses it in this posting of his, and if you wish to experience it, click on the posting link above. I plan on just using his 5 points that he believes clarify the issue and demonstrate that 2015 was not the hottest year. So here goes:
“Here is why they’re all talking rubbish and you needn’t worry about that “Hottest Year Evah” one bit.
- The satellite data show no warming
Compare the two trends (below): the upward one comes from the surface temperature dataset used by NASA GISS (and NOAA and the Met Office – they’re all pretty much interchangeable); the flat trend comes from the more accurate satellite data. Which one do you trust?
- NASA has fiddled the raw temperature data on an ‘unbelievable scale’
From the publicly available data, Ewert made an unbelievable discovery: Between the years 2010 and 2012 the data measured since 1881 were altered so that they showed a significant warming, especially after 1950. […] A comparison of the data from 2010 with the data of 2012 shows that NASA-GISS had altered its own datasets so that especially after WWII a clear warming appears – although it never existed.
