Who's data? Where did it come from, and what "adjustments" have been made to the data? I hope everyone realizes that in the climate scam data isn't just data. Temperature readings, particularly historical readings, have to be "adjusted" and "scaled" and "corrected" for all kinds of things like accuracy and precision of measurement instruments, land use, population, measurement bias... The dirty little secret in the climate scam is that the net effect of these "adjustments" to the data are often far bigger (sometimes an order of magnitude bigger) than the trends discovered in the data by their so-called research. Therefore, by applying the scaling factors and biases you want (those that suit and support your conclusions) you can get the data to show pretty much anything you want from a coming melt-down to the next ice age.
...the global average surface temperature for 2015 was 0.73 degrees C above the 1961-1990 average ...
...also found that global temperatures were approximately 1 degree C above the 1880-1899 period...
Anyone care to take a guess as to why the so-called "scientists" picked those two time periods as a basis for comparison to present-day? Anyone? If you said "because they are two of the coolest periods in measured history" ding ding ding, give yourself a prize. Sure, you can make now look hot if you compare it to a couple of unusually cool time periods. SMDH... Liars. Plain and simple scam artists trussed up in lab coats calling themselves scientists and researchers trying to put on a patina of respectability.
One additional point to consider:
Global temperature is best measured by satellites. Really, how on earth do we know the ‘global’ temperature in 1890? Do we really have reliable temperature readings from the middle of the oceans, the heart of Africa, Antarctica, etc?
The temperature ‘record’ prior to the 1970s (satellite age) is practically useless, when doing comparisons that get down to fractions of degrees.
