Simplified, to the point of absurdity.
And pointedly so; yet even when it's put in the most absurdly simple terms, there are
still people who will deny the nature of the data.
There are still people who will deny the entire historical dataset, including its periodicity, before the last 134 years, deny it has any relevance whatsoever except as a basis for the "spikes" they're asserting today, who will nevertheless continue to promote the idea that the apocalypse is upon us and sanctimoniously demand demonstably irrational, apocalyptic "solutions" - absurd schemes like massive taxation and regulation and 'cap and trade' - schemes which if you want to know the real truth is actually what this is all about - the opportunity to suck in a gullible group of people, feed them some tidbits of scientific data to assuage their inherent paucity of intellectual curiosity, and ride them and everyone else to wealth and power until this crisis not pan out and they find another one.
Did you know NOAA - the National Oceanic and Atmospheric Association claims to be some 200 years old? Fine group, generally - though they were only officially created in 1970 (that'd be 44 years ago for those here who may not want to do the math) - still, they lay claim to the entire history of the United States being (among obviously other things) playing a key role in climate science. Actually, they go back as far as 1643 to note that an American clergyman was the first 'American' (he lived in Delaware) to start observing the weather
American meterology began with the reverend John Campanius, a Swedish clergyman who settled near the present site of Wilmington, Delaware, in 1643. Campanius, the "first meteorological observer on the western continent," kept an account of the weather, day by day, during the years 1644--`45.1
Yep, he actually kept 2 years worth of weather data - 360 years ago. Thomas Jefferson and James Madison even kept their own records of local weather data.
The government didn't officially get involved though until 1814, when the Army Medical dept issued a rule, requiring its doctors and surgeons "keep a diary of the weather." In 1817, the Land Office issued a similar ruling for its local people at their offices around the country.
In 1840, the reputed James Espy gave to the British organization his vaunted "theory of storms" published a year later under the title "Philosophy of Storms" - no doubt a basis for some of the computer models we hear about today.
And it just expands from there. Clergymen, statestmen, politicians, doctors, surgeons, land office managers - virtually anyone interested in or ordered by the government to "diary data."

2014 is ostensibly hotter than anything they recorded.
