Climate Reality: The Long View – Slaying the Sky Dragon Excerpt
There is no long term connection between CO2 and global temperature.
NB: CO2 levels are currently close to the lowest they have been for 300 million years.
In the short term when temperatures rise there is a lag of several hundred years before CO2 levels rise. This because oceans take a long time to warm. CO2 is less soluble in warm water than in cold water.
If current CO2 levels were to halve, all plant life would die and humans with it!
CO2 is currently 0.038{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} of our atmosphere (compared to argon at 1{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117}).
Global temperatures have been on a long down-ward trend over the last six million years.
Based on ice core samples it is clearly evident global temperatures have been several degrees higher than now even as recent as the historical past. The current ‘rise’ of 0.5±0.3°C in the last forty years (this upward trend ceased 15 years ago and now shows signs of a decline) is therefore relatively trivial and certainly not abnormal.
Note during the Roman Warm Period grapes were being grown in southern Scotland and in the Medieval Warm Period there were vineyards in Yorkshire.
We are not even as warm as we were 800 years ago.
The Medieval Warm Period was a time of prosperity.
The Medieval Warm Period proved to be of high embarrassment to the UN IPCC.
In 2001 they published the infamous ‘hockey stick’ graph, which they subsequently had to drop in 2006, although it continues to be promoted by climate alarmists.
As can be seen the reality is very different.
The above graph is based on a large collection of ground based weather stations. It looks moderately alarming but in reality verges on the meaningless as the next graph below illustrates.
A possible change in average temperature of about 0.7°C in 120 years is no basis for alarm. On earth daily temperatures can fluctuate by as much as 40°C in some areas (deserts are good example).
In addition the accuracy of many weather station thermometers is in considerable doubt: many are poorly maintained and are sited in unsuitable places (such as airports and buildings subject to the Urban Heat Island effect – not readily perceived seemingly by climate alarmists) for gathering a global ‘temperature’.
A new array of free drifting ocean going buoys with sophisticated temperature sensors (ARGO*)has recently been deployed but it will be many years before any useful data analysis becomes available, even though initial data indicate a slight cooling of the oceans. *http://www.argo.ucsd.edu/
The graph below shows how the UN IPCC team pulled part of what can only be construed as further fraud.
In culling weather stations they conveniently removed stations located in the coldest areas. E.g. Bolivia, a mountainous cold country in the Andes, vanished from their ‘map’ and instead it was ‘averaged’ between the coast of Peru and the Amazon basin.
All that the UN IPCC can rely on now for its climate alarmism are the computer models.
These are essentially two-dimensional ‘discs’ employed to model the earth‘s climate using simplistic ideas and guesswork. They are, in effect, ‘flat-earth’ models.
They are so inadequate that in attempting to introduce mountains the air currents passing over them broke the sound barrier! They epitomize that oft applied saying about computers, “Garbage in, garbage out”.
Our climate is quite beyond human influence.
The main factors are: the sun‘s variability and activity, the lunar orbit, and our varying position in the solar system and in the galaxy.
On the earth the clouds and ocean currents control the overall temperature (not the other way round) and they respond primarily to these extra-terrestrial influences.
If you really want to worry, then worry about the next big ice age – due quite soon! They last around 80,000 years, interglacials (one of which we are now in) last between 12,000 and 20,000 years (maximum).
