German climate website: "Within the last few years, over 50 papers have been added to our compilation of scientific studies that find the climate’s sensitivity to doubled CO2 (280 ppm to 560 ppm) ranges from <0 to 1°C. When no quantification is provided, words like 'negligible' are used to describe CO2’s effect on the climate. The list has now reached 106 scientific papers."

Princeton Physicist Dr. Will Happer & Former Trump Science Advisor: "We are here under false pretenses, wasting our time talking about a non-existent climate emergency." ... "Phoniness of this bizarre environmental cult." ...It's hard to understand how much further the shrillness can go as this started out as global warming then it was climate change or global weirding climate crisis climate emergency what next but stick around it will happen. I hope sooner or later enough people recognize the holiness of this bizarre environmental cult and bring it to an end."

Ex-Trump adviser Happer: ‘Brainwashed’ aides killed climate review

Ex-Trump official Dr. Happer: White House aides too ‘nervous’ about fallout to dispute ‘climate crisis’ claims

Climatologist Dr. Judith Curry: "For the past three decades, the climate policy ‘cart’ has been way out in front of the scientific ‘horse’. The 1992 Climate Change treaty was signed by 190 countries before the balance of scientific evidence suggested even a discernible observed human influence on global climate. The 1997 Kyoto Protocol was implemented before we had any confidence that most of the recent warming was caused by humans. There has been tremendous political pressure on the scientists to present findings that would support these treaties, which has resulted in a drive to manufacture a scientific consensus on the dangers of manmade climate change. Fossil fuel emissions as the climate ‘control knob’ is a simple and seductive idea. However this is a misleading oversimplification, since climate can shift naturally in unexpected ways." ...

"We have no idea how natural climate variability (solar, volcanoes, ocean circulations) will play out in the 21st century, and whether or not natural variability will dominate over man-made warming. We still don’t have a realistic assessment of how a warmer climate will impact us and whether it is ‘dangerous.’ We don’t have a good understanding of how warming will influence extreme weather events.  Land use and exploitation by humans is a far bigger issue than climate change for species extinction and ecosystem health. Local sea level rise has many causes, and is dominated by sinking from land use in many of the most vulnerable locations." ...

"We have been told that the science of climate change is ‘settled’. However, in climate science there has been a tension between the drive towards a scientific ‘consensus’ to support policy making, versus exploratory research that pushes forward the knowledge frontier." ...

"Nevertheless, activist scientists and the media seize upon each extreme weather event as having the fingerprints of manmade climate change — ignoring the analyses of more sober scientists showing periods of even more extreme weather in the first half of the 20th century, when fossil fuel emissions were much smaller." ...

"We have been told that climate change is an ‘existential crisis.’ However, based upon our current assessment of the science, the climate threat is not an existential one, even in its most alarming hypothetical incarnations."

Now scientists have found that CO2 – to the extent that it has a “negligible” influence on temperature – causes the climate to cool from winter to summer and to warm from summer to winter.

Geologist Dr. Robert Giegengack - Former chair of Department of Earth and Environmental Science at the University of Pennsylvania: 

Giegengack laments "the enormity of the hubris that leads us to believe that we can 'control' climate by controlling anthropogenic emission of CO2."

"If anthropogenic CO2 is contributing to climate warming now under way, nothing we are doing, or contemplating doing, can have any measurable effect on that warming."

Global Warming/Climate Change has evolved into "a semi-religious campaign advanced by well-intended people who feel, deep in their hearts, that they are 'saving the planet.'"

"It beggars the imagination to assert that the natural factors that drove the warming trend from 18,000 years ago to ~300 years ago (with some unexplained temperature reversals) abruptly stopped operating at the end of the Little Ice Age to accommodate our political need to attribute climate variability to human industrial activity."

"Today’s climate is close to the coolest it has been in 540,000,000 years, and the atmospheric concentration of CO2 is close to the lowest it has been."

"Climate models are instructive, but they lead to scenarios, not predictions. They can be manipulated to yield desired outputs."
