The UN has a special summit on climate on 23rd September and the alarmist wind-up has started (though the leaders of India, China and Gernany will not attend). The World Meteorological Organisation (WMO) has kicked off on the hype with a bulletin pointing out that CO2 concentration in the atmosphere has reached 396 ppm(v/v) which is an increase of 3 ppm from the previous year. It is – they say – the fastest rate of increase since 1984.
The WMO is just another advocacy group and their conclusions seem to be based more on wishful thinking rather than on any knowledge.
(My comments in red)
Comment 1: If this rate of increase occurred also thirty years ago in 1984 when the world’s consumption of fossil fuels was an order of magnitude less than today then the increased use of fossil fuels is clearly not as great a contributor to CO2 concentration in the atmosphere than previously thought.
BBC: A surge in atmospheric CO2 saw levels of greenhouse gases reach record levels in 2013, according to new figures. Concentrations of carbon dioxide in the atmosphere between 2012 and 2013 grew at their fastest rate since 1984. The World Meteorological Organisation (WMO) says that it highlights the need for a global climate treaty. …..
According to the bulletin, the globally averaged amount of carbon dioxide in the atmosphere reached 396 parts per million (ppm) in 2013, an increase of almost 3ppm over the previous year. “The Greenhouse Gas Bulletin shows that, far from falling, the concentration of carbon dioxide in the atmosphere actually increased last year at the fastest rate for nearly 30 years,” said Michel Jarraud, secretary general of the WMO. ….. However, global average temperatures have not risen in concert with the sustained growth in CO2, leading to many voices claiming that global warming has paused.
Comment 2: The logical conclusion is that CO2 concentration has little impact on global temperature. The undoubted “greenhouse” effect of CO2 is clearly being suppressed by other negative feedbacks.
“The climate system is not linear, it is not straightforward. It is not necessarily reflected in the temperature in the atmosphere, but if you look at the temperature profile in the ocean, the heat is going in the oceans,” said Oksana Tarasova, chief of the atmospheric research division at the WMO.
Comment 3: This is now “global warming” restricted by magic mechanisms to hiding in the deep oceans and which is no longer visible in the atmosphere!!!! “Climate science” is trying to rewrite the laws of thermodynamics and heat flows.
The bulletin suggests that in 2013, the increase in CO2 was due not only to increased emissions but also to a reduced carbon uptake by the Earth’s biosphere. The scientists at the WMO are puzzled by this development. That last time there was a reduction in the biosphere’s ability to absorb carbon was 1998, when there was extensive burning of biomass worldwide, coupled with El Nino conditions.
“In 2013 there are no obvious impacts on the biosphere so it is more worrying,” said Oksana Tarasova. “We don’t understand if this is temporary or if it is a permanent state, and we are a bit worried about that.”
“It could be that the biosphere is at its limit but we cannot tell that at the moment.” The WMO data indicates that between 1990 and 2013 there was an 34% increase in the warming impact on the climate because carbon dioxide and other gases like methane and nitrous oxide survive for such a long time in the atmosphere.
Comment 4: Fundamentally the WMO does not know very much about the biosphere and its impact on CO2, and even less about the impact of CO2 on global temperature. Why is the WMO then advocating action on parameters, the effects of which are unknown?
The only things that the WMO bulletin demonstrates are that the linkage between CO2 concentration and global temperature is unknown (if it is even significant), and that the linkage between fossil fuel combustion and atmospheric CO2 concentraion is uncertain.
Hardly a sound basis for the idiotic demonisation of fossil fuel combustion.
