A June, 2019 research paper concludes that human activity can account for no more than a 0.01C rise in global temperatures, and goes so far as to “prove” low-level clouds “practically control the global temperature”.
In this paper we will prove that GCM-models used in IPCC report AR5 fail to calculate the influences of the low cloud cover changes on the global temperature. That is why those models give a very small natural temperature change leaving a very large change for the contribution of the green house gases in the observed temperature. This is the reason why IPCC has to use a very large sensitivity to compensate a too small natural component. Further they have to leave out the strong negative feedback due to the clouds in order to magnify the sensitivity. In addition, this paper proves that the changes in the low cloud cover fraction practically control the global temperature.
This essay from director of NSIDC, Mark Serreze, is provided for reference. You may remember Serreze who once said “the Arctic is screaming” while botching and then backpedaling on claims of “ice free summers” on the near horizon for the Arctic that never happened. Give it all the consideration it is due. For some perspective, see my article on a previous 100 degree event above the Arctic circle over 100 years ago. By the way, with 24 hours daylight above the Arctic circle, and near 24 hour daylight in Siberia this time of year, (the first day of summer aka the summer solstice) is it any surprise it would get warm?
On behalf of environmentalists everywhere, I would like to formally apologize for the climate scare we created over the last 30 years. Climate change is happening. It’s just not the end of the world. It’s not even our most serious environmental problem.
I may seem like a strange person to be saying all of this. I have been a climate activist for 20 years and an environmentalist for 30.
But as an energy expert asked by Congress to provide objective expert testimony, and invited by the Intergovernmental Panel on Climate Change (IPCC) to serve as Expert Reviewer of its next Assessment Report, I feel an obligation to apologize for how badly we environmentalists have misled the public.
Here are some facts few people know:
Humans are not causing a “sixth mass extinction”
The Amazon is not “the lungs of the world”
Climate change is not making natural disasters worse
Fires have declined 25% around the world since 2003
The amount of land we use for meat — humankind’s biggest use of land — has declinedby an area nearly as large as Alaska
The build-up of wood fuel and more houses near forests, not climate change, explain why there are more, and more dangerous, fires in Australia and California
Carbon emissions have been declining in rich nations for decades and peaked in Britain, Germany and France in the mid-seventies
Adapting to life below sea level made the Netherlands rich not poor
We produce 25% more food than we need and food surpluses will continue to rise as the world gets hotter
Habitat loss and the direct killing of wild animals are bigger threats to species than climate change
Wood fuel is far worse for people and wildlife than fossil fuels
Preventing future pandemics requires more not less “industrial” agriculture
I know that the above facts will sound like “climate denialism” to many people. But that just shows the power of climate alarmism.
