questioning whether rising CO2 levels
really will lead to a catastrophic rise
in global temperatures.
Should we instead be worrying
about the risks of falling levels of CO2?
But then the suggestion that
small increases in atmospheric CO2 are leading to runaway global
heating and climate breakdown is also an unproven scientific
hypothesis supported by many eminent scientists.
He also noted that,
Behind the current climate hysteria is the suggestion that placing more CO2 into the atmosphere by humans burning fossil fuel will cause global temperatures to rise since the gas traps the sun's heat reflected from Earth.
It is true that CO2 acts as a greenhouse gas, but only within certain bands on the infrared spectrum.
This has led some scientists, notably Professor William Happer of Princeton University, to suggest that CO2 becomes "saturated" once it reaches a certain level.
Most, if not all, the heat that is going to be
trapped will have already been radiated back by the CO2 molecules
evenly distributed in the existing atmosphere.
CO2 levels have risen steadily over the last 100 years despite temperatures rising from 1910-40, falling until around 1980, (remember the global cooling scare?) rising briefly for 20 years and then plateauing for the last two decades.
Further back, CO2 levels seemed to have remained fairly constant through the warmings of 6,000 years ago and the Roman and Mediaeval periods.
The subsequent 'little ice age' also registered no significant CO2 change. Since about 1820, temperatures and CO2 levels started to nudge upwards long before any human input could have been significant.
Looking back further into geological time reveals little obvious pattern across nearly 600 million years.
massive jump in temperature in the Permian period occurred as the
CO2 level fell. During the time of the dinosaurs, temperatures
showed a fall as CO2 rose and then jumped higher as CO2 trended
Climate models have been around for 40 years making guesses about global warming that are politically correct, but almost certainly factually wrong.
unimpressed with their efficacy, noting that they struggle even to
replicate the past. In the absence of clear answers from climate
science, almost all net zero political policy is based on the
outputs of unreliable models.
It is just that - an assumption...
Given that it is actually a guess and some evidence that the
greenhouse effect drops significantly once a base CO2 level is
reached, the hypothesis is unproven and certainly not 'settled' with
any credible, peer reviewed science.
Life has thrived during this period but gradually carbon has been sequested by dead plant matter and animals in coal deposits and various rocks including limestone and marble.
Dr. Patrick Moore, one of the original founders of Greenpeace, notes that 99.9% of all carbon that has ever entered the atmosphere has been captured in this way.
The scale of carbon captured in this way
not disputed by other scientists who suggest 90% of carbon has been
locked up over geological time.
But in just the last 40 years the small uptick in CO2 has led to an estimated 14% extra vegetation on the Earth, alleviating food shortages and famine in many parts of the world.
It is unsurprising that Moore is relaxed about more CO2 in the atmosphere.
Dr. Roy Spencer, the former Senior Scientist for Climate Studies at NASA, also notes that plants benefit from higher levels of CO2, adding,
All of which begs the question,
The cost of net zero is almost unimaginable and the potential for economic and societal disruption on a global scale is the stuff of nightmares.
Removing 85% of the world's energy by banning fossil fuels within just 35 years and replacing them with unreliable and expensive renewables is pure fantasy...
Wouldn't it be nice if we didn't have to do it?
As with many independent commentators, he is particularly contemptuous about attempts to keep the hysteria alive by cherry picking bad weather events.
It might take the mainstream media led by the BBC, Sky and the Guardian a little longer to come around, but expecting citizens to accept massive changes to their ways of life on the basis of patently false doomsday predictions only works for so long - as we're starting to see with Covid...
Just before his death, Clive James discussed climate scares and noted that after a while people switch over to watch Games of Thrones,
