NASA, NOAA Analyses Reveal Record-Shattering Global Warm Temperatures In 2015 (nasa.gov)
vikingpower writes: Earth's 2015 surface temperatures were the warmest since modern record keeping began in 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA). Globally-averaged temperatures in 2015 shattered the previous mark set in 2014 by 0.23 degrees Fahrenheit (0.13 Celsius). Only once before, in 1998, has the new record been greater than the old record by this much. The British Met office also reports on the same phenomenon, even forecasting that global temperatures are very soon going to reach the one-degree-Celsius marker. According to Stephen Belcher, Director of the Met Office Hadley Centre, "We've had similar natural events in the past, yet this is the first time we're set to reach the 1 C marker and it's clear that it is human influence driving our modern climate into uncharted territory."
This has been discussed here so often that even I have heard about it.
You have 100 100-year-old monitoring stations. You have new ones that were started more recently. To examine 100 year trends, do you
[a] ignore the more recent stations and do not correct for anything, even though this will bias your results towards more warming due to urbanization
[b] ignore the more recent stations and adjust the historical temperatures based on ???
[c] use all available data and try to correct for as many effects as you can think of
Doing anything, or not doing anything, has the potential to throw your numbers off. Unless you have some specific evidence that what has been done is not statistically rigorous do shut up. That also goes for the case where you don't have data to say one way or the other. There is not some massive conspiracy to fuck with the numbers here.
Before anyone decides to mod me down as a troll, consider that teh denialists still deny when even one of their stalwarts of denial - Exxon - has known for years that AGW was real, but decided on a tactic of "sowing doubt" http://insideclimatenews.org/n... while their own researcers concluded AGW was real.
Not being able to produce credible research to prove their denialism, they are left with a smaller and smaller set of cherrypicking data, character assassination, and the always popular "I looked out the window and its cold today - so much for global warming!"
So in moves remarkably similar to tobacco idustry lawyers managing to deny that there was proof that tobacco caused cancer when there was ample evidence in the 1800's, or creationists claiming that dinosaurs and humans romped merrily together - but nol earlier than 4004 b.c.e. - based on long discredited fossil tracks in places like http://www.talkorigins.org/faq... Paluxy, Texas - Indeed, Ken Hamm's Creationism museum has that as biblical proof of young earth creationism - the denialists are getting backed into a smaller and smaller corner, soon to be left only with fingers stuck in their ears, and chanting "Neener never never - I can't hear you!"
So if anyone has the disproving research I'd love to see it. If not, just mod me down to oblivion, and prove what I just wrote.

Ever notice how you human-made climate change morons never have any evidence to backup what you say?
Ever notice how you just coveniently ignore any evidence presented to you about anthropogenic climate change?
Climate Science:
(a) The current theory of 'Greenhouse Gases' relies on the observation of the temperature at the earths surface, which fluctuates less than we would expect and is also (on average) higher than we would expect in comparison to a control body (say, the Moon). A similar observation may be made at various heights within the atmosphere. This phenomena can't be explained by observing the properties of the most common atmospheric components (Nitrogen and Oxygen) but less common components demonstrate behaviors (in terms of how they absorb and radiate radiation in the visible and infra red spectra) which account for the differential in both base temperature and variability. These are termed 'The Greenhouse Gases'.
(b) These observations are recorded and can be remeasured by anyone who feels the urge to do so. Repeated observations have yielded the same result, without exception, for 150 years.
(c) Various mechanisms were misunderstood in the earlier hypothesis (by Fourier and Tyndall) but these were acknowledged, corrected, and the modified hypothesis did not contradict the earlier observations.
(d) No fallacy, or rhetoric is necessary to prove the hypothesis, it is entirely demonstrated via independent, objective observation.
The Denier Hypothesis
(a) There is no apparent hypothesis. NO hypothesis has been proposed to explain the atmospheric temperature differential from a baseline control, or the measured differential at different zones within the atmosphere.
(b) There is no way to independently verify any observations because no observations have been published.
(c) Numerous assertions from Denialism have been disproven, without any forthcoming acknowledgement, nor adjustment to the underlying theory to match with new observations. The assertions include: saying that no temperature rise has occurred (disproven by observation), saying that the temperature was due to solar variance (disproven by observation), saying that the increased concentrations of CO2 were due to volcanoes (disproven by observation). et cetera. These theories are inherently contradictory but are often present in the same conversation (2 of these can be noted in this very thread)
(d) The Denier hypothesis makes frequent use of rhetoric: it is rarely presented without some rhetorical device (appeals to emotion e.g. "I'm concerned/confused" false equivalence e.g. "I'm not sure who to believe anymore" burden of proof fallacy e.g. "Why doesn't someone explain x to me?" ).
When considered using these criteria the choice seems pretty clear.
I'm curious how the data can be compared reliably seeing as even assuming that all the thermometers used at the turn of the century were perfectly crafted, properly calibrated, cared for properly, placed properly, and recorded properly they STILL would have had an error rate of +-0.5 degrees Fahrenheit. In reality you can almost certainly at the very least double the error rate. Which means that any trends prior to more accurate recording devices aren't possible to compare.
See the law of large numbers. It is possible to get arbitrarily good estimates by combining sufficiently many fuzzy individual measurements. This is not an invention of some communist cabal of climate scientists, but was formalised by Bernoulli and Poisson in the 18th and 19th century. And it is, of course, used in every modern tracking radar system, wether to keep moving bodies apart or to bring them together.
That being said, even assuming arguendo that CO2 driven AGW is occuring, the solutions still have jack all to do with renewable energy. There are three possible solutions to the problem of large impact AGW, they are slaughter 90+% of the human race, try to chemically engineer the weather with various geoengineering attempts, or figure out a way to sequester carbon on a VERY large scale. Any other options are the fucking definition of whistling in the dark.
Thank's for your well-considered opinion. I'm sure both I and the world will give it the attention it deserves.
