**Pre-Obama, the 1930s were the warmest period on record. Obama's "scientists" adjusted the old records downward, apparently for political reasons. The "Harry read me" file, released as part of the Climategate emails, documents how the historical weather station records are in a hopeless mess. This state of affairs allows a variety adjustments to be justified and makes the process of adjustment quite subjective.<br/>I use the satellite records myself, although they go back only to 1978. According to the [http://www.drroyspencer.com/latest-global-temperatures/ UAH record], 2016 was the warmest year on record and 1998 was the second warmest. Record warm years have more to do with the El Nino weather cycle than with global warming.
