believer bernard shawWas talking to a friend the other day, and she asked whether I believed in Climate Change. I responded with, “science is not about belief, but about facts”. Then she used the “Denier” term in respect to Climate Change facts. I promised to share some facts with her.

Here ya go Amy.

Fact 1

It is not actually possible to measure the earths temperature. Let alone compare current temperatures to past temperatures to get accurate global trends.  There is insufficient weather stations in some key locations, like Africa, the Arctic, the Antarctic, and oh yes, the oceans. The oceans are kinda catered for but the rest are typically “infilled” with data (guestimated?).  There has also been changes to the number of, and the locations of measuring stations as well as varying methods of recording.  Probably the best method we have to measure the earth’s temperature are the satellites. But these only cover the last 37 years, and have a few minor issues of there own.

Fact 2

Temperature data may not be what you think it is. Station siting in once rural areas and now in growing urban areas are affected by UHI. Homogenised data sets can be quite different from the raw data, creating different trends than were originally indicated.

Records in the US and Australia have had their past temperatures predominantly reduced, producing long term warming trends where there was little or none in the original records. I have seen direct evidence of this in the Adelaide record, and in NOAA data.

Fact 3

 

Every prediction/projection from Climate Scientists and promoters of CAGW has not been realised. The Arctic has not melted away. The Polar bears are increasing in population. The temperature has not risen as stated by the IPCC. The seas have not risen catastrophically. Storms have not gotten worse. There are no climate refugees.  Australia and Texas are no longer in “permanent drought”. Crop yields have increased around the world. The Antarctic has been growing in ice. Standard of living has increased in the vast majority of countries.  Children still know what snow is.

beliefs vs facts

Fact 4

Sea levels around the world vary in their rates of rise (or fall). Long term gauges average 1.5mm rise per year. Global sea levels starting rising 200 to 300 years ago, with yearly trends of 1.35mm and less than 1mm (dependant on which study).  The satellite record for sea level indicates about 3mm per year since 1993.  There is a disconnect between gauges and satellite results. Satellite data indicates a rate much higher than the average of tide gauges. All stated rates are far below what the IPCC has forecast.

Fact 5

Storms are not increasing in number or severity. No increase trend in accumulated cyclone energy.  There has been a decrease in overall cyclones. The number of US tornadoes are not increasing.  Cat 3 and above tornadoes have a decreasing trend.

Fact 6

Arctic ice has been reducing in area since 1979, however the satellite record prior to 1979 is never published on line by NASA, and shows ice area peaked in 1979 and had been much less in the years before. Not too dissimilar to the current levels.

Fact 7

Antarctic ice and Greenland snow and ice have been increasing over the satellite record.

Fact 8

The ice cores show that CO2 predominantly increases after the temperature. Mostly after 800 years. The science of ice core analysis is problematic and the CO2 concentrations in the ice core may not be representative of CO2 in the atmosphere, over the noted history.

cock sure stupid

Fact 9

The current CO2 data from Mauna Loa has been tacked onto CO2 data from the ice cores producing one long record, however, as stated above the ice core gasses may not be directly comparable to real world measurements. There is also a historical gap of 83 years which was erased to connect the two data sets, to form one continuous record. The Keeling curve.

Fact 10

Climate models predicted a “hot spot” in the atmosphere due to CO2 warming. This hot spot has never been observed.

Fact 11.

It is not possible to directly attribute any weather event or warming episode over short or long periods solely or even partially to CO2.  There are too many variables influencing weather and climate to make clear connections.

 

Fact 12.

The projected temperature rise per the IPCC model mean, is currently much higher and diverging from both satellite records.

Fact 13.

The reported rise in global temperature from NOAA since 1880 is about 0.8°C.  That is all.

Fact 14.

The reported rise in temperature from NOAA/NCDC from 1960 to 2017(blamed on AGW)  is within 0.1°C of being the same as the temperature rise from 1910 to 1941(apparently natural causes)

einstien consensus

Fact 15.

The yearly error bars on the NOAA/NCDC global temperature data set prior to 1952 is 0.4°C. Half of the reported total rise.

Fact 16.

The survey purporting to the 97% consensus has been found to be flawed statistically, and in methodology.

Fact 17.

The earth is getting greener.

Fact 18.

Cold kills far more people than heat.

Fact 19.

The IPCC is a UN body chartered with the task of gathering evidence to support the theory of AGW, and to recommend policy to governing bodies around the world. It is not chartered to gather any evidence that does not support the theory of AGW.

Fact 20.

CO2 is not listed as a pollutant on the Australian or US government pollutants list. It is however, plant food.

einstein

In closing.

This list of facts that bring into question the authenticity of the CAGW theory is by no means complete.  There is much more.  And more in this video.

But given just this information above, it is difficult to imagine that the science of AGW, CAGW, Climate Change, or Climate Disruption, is so settled.  Science by definition is never “settled”, and it is never agreed on by “consensus”. Even if CO2 does have a net warming effect on the earth, it appears that it is not as much as stated by the IPCC, and it appears not to be catastrophic.  Any additional warmth appears to have had far more benefits than any of the projected negatives.

There also appears to be some heavy bias in the “climate” community towards the AGW theory.  Ommition, mirepresentation, and alteration of information and data which would bring into question the AGW theory is common.  Funding and research is popular for any AGW supported area, while any other climate research not supporting AGW is either not funded, or obfuscated, or outright rejected in peer review.

So

Should I believe in Climate Change?

If I did, I might be denying much more than just a scientific theory.

Facts are pesky little buggers, arn’t they.
