An interesting set of research is being published. From Zero Hedge:
Bombshell Claim: Scientists Find "Man-made Climate Change Doesn't Exist In Practice"
A new scientific study could bust wide open deeply flawed fundamental assumptions underlying controversial climate legislation and initiatives such as the Green New Deal, namely, the degree to which 'climate change' is driven by natural phenomena vs. man-made issues measured as carbon footprint. Scientists in Finland found "practically no anthropogenic [man-made] climate change" after a series of studies.
“During the last hundred years the temperature increased about 0.1°C because of carbon dioxide. The human contribution was about 0.01°C”, the Finnish researchers bluntly state in one among a series of papers.
This has been collaborated by a team at Kobe University in Japan, which has furthered the Finnish researchers' theory: "New evidence suggests that high-energy particles from space known as galactic cosmic rays affect the Earth's climate by increasing cloud cover, causing an 'umbrella effect'," the just published study has found, a summary of which has been released in the journal Science Daily. The findings are hugely significant given this 'umbrella effect' — an entirely natural occurrence — could be the prime driver of climate warming, and not man-made factors.
The scientists involved in the study are most concerned with the fact that current climate models driving the political side of debate, most notably the Intergovernmental Panel on Climate Change's (IPCC) climate sensitivity scale, fail to incorporate this crucial and potentially central variable of increased cloud cover.
"The Intergovernmental Panel on Climate Change (IPCC) has discussed the impact of cloud cover on climate in their evaluations, but this phenomenon has never been considered in climate predictions due to the insufficient physical understanding of it," comments Professor Hyodo in Science Daily. "This study provides an opportunity to rethink the impact of clouds on climate. When galactic cosmic rays increase, so do low clouds, and when cosmic rays decrease clouds do as well, so climate warming may be caused by an opposite-umbrella effect."
In their related paper, aptly titled, “No experimental evidence for the significant anthropogenic [man-made] climate change”, the Finnish scientists find that low cloud cover "practically" controls global temperatures but that “only a small part” of the increased carbon dioxide concentration is anthropogenic, or caused by human activity.
I can see that. Geologic record has the CO2 concentration changing about 800 years after the global temperature changes. CO2 is a lagging indicator and not a driver. Besides, Earth's CO2 used to be 9,000PPM instead of today's 460PPM and we are doing just fine.
