Seems like the graphs NOAA creates and the data it publishes don't match the raw data. Interesting link for those truly interested. "Climate Central just ran this piece, which the Washington Post picked up on. They claimed the US was overwhelmingly hot in 2016, and temperatures have risen 1,5°F since the 19th century." "The first problem with their analysis is that the US had very little hot weather in 2016. The percentage of hot days was below average, and ranked 80th since 1895. Only 4.4% of days were over 95°F, compared with the long term average of 4.9%. Climate Central is conflating mild temperatures with hot ones." "The problem with the NOAA graph is that it is fake data. NOAA creates the warming trend by altering the data. The NOAA raw data shows no warming over the past century" The adjustments correlate almost perfectly with atmospheric CO2. NOAA is adjusting the data to match global warming theory. This is known as PBEM (Policy Based Evidence Making.) The hockey stick of adjustments since 1970 is due almost entirely to NOAA fabricating missing station data. In 2016, more than 42% of their monthly station data was missing, so they simply made it up. This is easy to identify because they mark fabricated temperatures with an E in their database. http://realclimatescience.com/2016/12/100-of-us-warming-is-due-to-noaa-data-tampering/
Not accounting for known and provable biases in the data would be scientifically unethical though. They make the adjustments because it's necessary. Raw data does not always represent reality (in fact it rarely does). In fact, NOAA's premiere weather model the GFS has a very complex system for bias correcting measurements as part of its data assimilation subsystem. If it didn't do this our weather forecasts would be far less useful than they are now.
Goddard/Heller is just repeating his old garbage science, which has been debunked many times before. Boring. Those who know the science know that the adjustments to raw data, globally, have made the warming look smaller. That's not debatable. http://variable-variability.blogspo...zation-adjustments-reduce-global-warming.html Hence, that denier conspiracy theory crashes and burns. Temperature adjustments are complicated, too complicated to discuss in detail here. These links will give anyone more than they ever want to read about the topic, and they include a point-by-point takedown of Goddard/Heller's nonsense. https://archive.is/ATAIL http://rankexploits.com/musings/2014/how-not-to-calculate-temperature/ http://rankexploits.com/musings/2014/how-not-to-calculate-temperatures-part-2/ http://rankexploits.com/musings/2014/how-not-to-calculate-temperatures-part-3/ https://moyhu.blogspot.com.au/2014/05/the-necessity-of-tobs.html https://variable-variability.blogspot.com.au/2012/08/a-short-introduction-to-time-of.html http://web.archive.org/web/20070704012242/tamino.wordpress.com/2007/05/11/best-estimates/ http://web.archive.org/web/20090216...ss.com/2006/11/08/tales-from-the-thermometer/
Newsflash, our weather forecast change daily as does the ever changing predictions for global warming with its warmer, oops they mean colder winters and it's hotter, oops they mean cooler summers and it's melting polls, oops they don't mean the Arctic and it's melting glaciers, oops they don't mean the ones that are growing.....
Newsflash, numerical weather prediction is FAR more reliable and accurate than most people realize. http://www.emc.ncep.noaa.gov/gmb/STATS_vsdb/ Anyway, my point is that bias correction is a VERY common thing to apply when dealing with instrumentation and is in no way alarming or concerning. In fact, the exact opposite is the case. It would be alarming and concerning if they didn't apply bias correction. You would then say the data was presented unethically.
Weather forecast here and everywhere changes daily and five to ten year AGW predictions fail every time yet true believers want us to shape our economy and energy policy based on them. AGW will soon be a footnote in history and it's true believers will be all worked up over the next in a long line of doomsday prophecy
