A few people sent me a link to this article, which may be of interest to those following the ongoing climate debates:
It turns out the UN’s Intergovernmental Panel on Climate Change has over-estimated future global warming by as much as 10 times, [Dr David Evans] says.
“Yes, CO2 has an effect, but it’s about a fifth or tenth of what the IPCC says it is. CO2 is not driving the climate; it caused less than 20 per cent of the global warming in the last few decades”.
Dr Evans says his discovery “ought to change the world”.
“But the political obstacles are massive,” he said.
His discovery explains why none of the climate models used by the IPCC reflect the evidence of recorded temperatures. The models have failed to predict the pause in global warming which has been going on for 18 years and counting.
“The model architecture was wrong,” he says. “Carbon dioxide causes only minor warming. The climate is largely driven by factors outside our control.”
There is another problem with the original climate model, which has been around since 1896.
While climate scientists have been predicting since the 1990s that changes in temperature would follow changes in carbon dioxide, the records over the past half million years show that not to be the case.
So, the new improved climate model shows CO2 is not the culprit in recent global warming. But what is?
Dr Evans has a theory: solar activity. What he calls “albedo modulation”, the waxing and waning of reflected radiation from the Sun, is the likely cause of global warming.
He predicts global temperatures, which have plateaued, will begin to cool significantly, beginning between 2017 and 2021. The cooling will be about 0.3C in the 2020s. Some scientists have even forecast a mini ice age in the 2030s.
