Is average global temperature warming or cooling?

Temperature Evidence

1. Dr. Friedrich Karl Ewert, retired geologist & data computation expert, examined all NASA GISS’s temperature data series, from 1153 stations, going back to 1881. On comparing raw data to NASA’s revisions he found earth has been cooling since 1940, not warming.
2. The GHCN climate stations show there is no statistically significant warming – or cooling. GHCN = Global Historical Climatology Network.
3. The UAH statellite record shows 0.3C warming in the last 40 years. But the climate also showed considerable cooling from 1940s to mid-1970s and the satellite readings only date from 1978.

Uncorrected NASA GISS data should show warming because beginning with the climate scare (1988) vast numbers of climate surface stations were shut. Many of them rural. The stations left open are mostly urban which should be subject to the Urban Heat Island UHI effect, which has increased over time. So uncorrected data should show warming purely on the basis of this massive station shutdown with the warmest stations surviving. If no warming was found (as is the case since the early 1940s) I conclude the climate must be cooling.

Science, as it was once imagined

It’s a kind of scientific integrity, a principle of scientific thought that corresponds to a kind of utter honesty–a kind of leaning over backwards. For example, if you’re doing an experiment, you should report everything that you think might make it invalid–not only what you think is right about it: other causes that could possibly explain your results; and things you thought of that you’ve eliminated by some other experiment, and how they worked–to make sure the other fellow can tell they have been eliminated.

Details that could throw doubt on your interpretation must be given, if you know them. You must do the best you can–if you know anything at all wrong, or possibly wrong–to explain it. If you make a theory, for example, and advertise it, or put it out, then you must also put down all the facts that disagree with it, as well as those that agree with it. There is also a more subtle problem. When you have put a lot of ideas together to make an elaborate theory, you want to make sure, when explaining what it fits, that those things it fits are not just the things that gave you the idea for the theory; but that the finished theory makes something else come out right, in addition.

In summary, the idea is to give all of the information to help others to judge the value of your contribution; not just the information that leads to judgement in one particular direction or another.

Arctic Warming

This is due to warmer temperatures in Winter. Whereas it used to be very cold there, it is now just cold.

Arctic ice isn't about to collapse because 'global warming' makes nights, winters, and very cold regions (such as the Arctic) slightly warmer. All of that is good for people.

Much of the work that supports the AGW conjecture is based on these inherently useless simulations.

The reality is that based on the paleoclimate record and the work done with models, the climate change we have been experiencing is caused by the sun and the oceans over which mankind has no control. There is no real evidence that CO2 has any effect on climate and plenty of scientific rational to support the idea that the climate sensitivity of CO2 is zero. The AGW conjecture is based on only partial science and is full of holes. For example, the AGW conjecture depends upon the existence of a radiant greenhouse effect in the Earth’s atmosphere caused by trace gases with LWIR absorption bands. Such a greenhouse effect has not been observed in a real greenhouse, in the Earth’s atmosphere or anywhere else in the solar system for that mater. The radiant greenhouse effect is science fiction hence the AGW conjecture is science fiction as well. Computer simulation of the weather is only reasonable good for about 10 days. The climate simulations are not as good as the weather simulations because of an increase in spatial and temporal sample sizes and inherent instabilities with the simulation process. The idea that adding CO2 to the atmosphere is hard coded into the simulations, begs the question and makes the climate simulations useless. Much of the work that supports the AGW conjecture is based on these inherently useless simulations.

Telling the public that the AGW conjecture is not based on only partial science is pure propaganda and should not be supported with the tax dollars. The federal government should not be funding explanations of global warming and the greenhouse effect that are just plane wrong.
