A natural cooling process which reverses the effects of global warming could be nearly twiceas powerful as scientists previously believed.
These VOCs cause the climate to cool and may explain why world temperatures have remained stable for around 15 years, despite widespread claims that global warming is out of control.
The German government’s Leibniz Institute for Tropospheric Research found a key VOC known as Isoprene, which was only thought to have been produced by living organisms such as plankton, is actually also created by the sun hitting chemicals at the top of the ocean.
Measurements had estimated 1.9 megatons of isoprene was emitted each year but the new, groundbreaking discovery shows an increase of between 0.2 and 3.5 megatons annually.
Instead, they claim, it suggests any man-made damage is being countered by the planet’s natural cooling processes.
Dr Benny Peiser, director of the Global Warming Policy Foundation, said: “Here is more evidence of what we have known for some time: that climate models simply do not mirror the reality of a [complex] system – and that they should never have been trusted in the first place.”
The report shows isoprene is produced from non-living chemicals in the sea. After rising into the atmosphere, these help create clouds, which reduce temperatures.
LITR said: “Atmospheric chemists from France and Germany can now show that isoprene can also be formed without biological sources in the surface film of the oceans by sunlight and so explain the large discrepancy between field measurements and models.
“The new identified photochemical reaction is therefore important to improve the climate models.”
But a spokeswoman for the Campaign Against Climate Change, which calls for “urgent and resolute action” against climate change, disputed the findings.
She said: “It would be lovely to think that one new study could let us off the hook – that climate change isn’t happening.
“But it is simply a lie.
“Last year’s IPCC report that concluded that climate change was real, caused by humans, and needs urgent action, was based on over 30,000 scientific studies.”
