Global Warming Projections vs. Scientific Forecasting Principles


Who are you going to believe, me, or this New York Times headline: "America in Longest Warm Spell Since 1776"?
.
I strongly suggest you should believe me, rather than the leftist-biased New York Times, because I don't vote for Democrats or Republicans, and have no reason to support the beliefs of either political party.
.
I seek knowledge and reach conclusions best supported by accurate data -- conclusions that will change if new data demand a change -- in contrast to leftist beliefs, which never change, are never debated, and are the choice of the New York Times as 'all the news fit to print'!
.
That "Longest Warm Spell" headline, by the way, was from the March 27, 1933 New York Times. It was so hot in the 1930s that every year in recent decades leftist climate "scientists" have quietly revised average temperature of Earth data to make the 1930s cooler and cooler -- no need to let reality interfere with their precious global warming theory!
.
The Intergovernmental Panel on Climate Change (IPCC) was given the task of proving manmade CO2 is the sole cause of global warming, and a global warming catastrophe is coming. 
.
The IPCC was not given the task to study the climate without bias.
.
The IPCC forecast ("projection") is not based on scientific procedures.
.
It is merely the opinion of a small subset of "scientists" who concentrate on building computer models, rather than collecting data in the field, and doing experiments in a laboratory, like most scientists do.
.
The "climate" scientists really enjoy playing computer games in air conditioned offices at the taxpayer's expense, getting media attention by making scary climate predictions, and gaining sympathy by saying we all have to work together to save the Earth.
.
The fact that the IPCC forecast is merely personal opinions is deliberately obscured by mathematics and complex writing.
.
Based on research on the methodology for scientific forecasting since the 1930's, it is well known that "expert" opinions are not useful.
.
There are no scientific forecasts of global warming. 
.
Claims of global warming in the future have no more credence than claims of global cooling.
.
One common forecasting error is confusing correlation with causation.
.
In 4.5 billion years of Earth's history there is only one very short period when the concentration of manmade CO2 in the air and Earth's average temperature increased at the same time (1979 to 1998 for weather satellite data, or 1976 to 2002 for surface measurement data). 
.
That one brief period of correlation does not prove CO2 causes warming, especially when rising manmade CO2 was accompanied by global COOLING from 1940 to 1976 (surface measurements), and there was global COOLING again from 1998 through 2014 (weather satellite data).
.
An increase of manmade CO2 obviously did not start the warming in progress since the last ice age ended 18,000 years ago.
.
"Experts" tend to be poor forecasters, especially when they communicate with one another, work together, and get paid by  the same or similar sources (central governments).
.
"Experts" even more than laymen tend to ignore, or don't publicize, any evidence that contradicts their beliefs.
.
"Experts" are also likely to have communicated their opinions with published papers and speeches -- opinions usually stated with a high level of confidence -- and once their opinions have been communicated to the public, "experts" are reluctant to contradict themselves, even when new data suggests they were wrong.
.
"Experts" who use complex models may impress laymen, but those models harm the accuracy of forecasts by multiplying small errors, creating more opportunities for errors, and making the errors more difficult to find.
.
In general, ordinary people have far too much faith in "experts", and their faith increases when "experts" agree with each other.
.
Yet judgmental forecasts by "experts" are the least accurate method of forecasting.
.
"Expert" forecasts tend to be less accurate than a simple naive forecast, such as 'the climate next year will be the same as this year'. 
.
Computer models are merely mathematical ways to express personal opinions (informal guesses).
.
Using math rather than all words does not increase forecast accuracy.
.
Unlike other scientists, climate modelers have little interest in data collection and laboratory experiments -- they spend their time predicting the future with a mathematical structure that has little relation to reality.
.
Variations of solar energy reaching Earth, for example, are not considered important enough to include in climate models, believe it or not.
.
IPCC authors, some not even scientists, appear to be completely unaware of evidence-based principles for forecasting 
.
The IPCC mislabels as a forecast, the "expert" opinions of a small subset of people who study the climate, whose Summary is modified by central governments who are allowed to make revisions without the permission the original authors, and without even reading the Backup Documents (which are released many months later).
.
I do my best to refute the 45 years of global warming scaremongering because it diverts attention from real environmental issues, such as the gross pollution in China -- global warming scaremongering is only a disguised attack on free market economics, which lifts more people out of poverty than any other economic system.
.
People will continue to believe in global warming just as people will continue to believe the biblical creation story.
.
I have a very unusual and unpopular point of view -- I don't believe in anything without proof, so both the global warming scare and the biblical creation story sound like unproven nonsense to me. 
.
As an 'outsider' on both subjects, I find it amusing that most liberals seem to believe in a coming global warming catastrophe, but many think biblical creation theory is nonsense … while most conservatives seem to believe in the biblical creation theory, but many think the global warming scare is nonsense -- there are very few people who will publicly state they think both beliefs are nonsense!
.
Public policy should not be based on personal non-scientific beliefs of a coming global warming catastrophe -- a catastrophe that doesn't seem to be any closer after 45 consecutive years of dire warnings.
.
In fact, the trend of Earth's average temperature has been flat for the last 12 to 18 years, as CO2 rises, based on EVERY measurement methodology of the average temperature in use. 
.
Leftist-biased sources of news don't think you need to know that fact, so they never tell you! 
.
The IPCC cleverly calls the lack of warming a  "hiatus" -- an uncommon and confusing word that sounds like a medical condition which affects the abdominal muscles, and is usually  repaired with an outpatient surgery!
