Evolution and humans: can we control climate (Evolution)

Article from a climate scientist who is skeptical:


I pursued my graduate studies at one of the world’s leading universities for climate studies, the University of East Anglia in the UK. The Climatic Research Unit (CRU) there is responsible—along with the Hadley Centre—for developing global temperature datasets, known as HadCRUT datasets.


I understood that the University’s email system had been breached, and email content scientists from the CRU leaked to the public. The event is infamously known as “Climategate.”

It took me a few more years before I completely understood the implications of that email leak. Email exchanges between scientists from the CRU and other universities revealed a deliberate attempt to exaggerate the present warming and make it appear unprecedented.

Ross McKitrick in “Understanding the Climategate Inquiries” showed how the evidence proves that “The scientists involved in the email exchanges manipulated evidence in IPCC [Intergovernmental Panel on Climate Change] and WMO [World Meteorological Organization] reports with the effect of misleading readers, including policymakers.”


The Climategate episode certainly made me question whether the global warming was as dangerous as it is made up to be.

The answer to my question trickled in slowly over a number of years. Evidence began to emerge that scientists acknowledged a large gap between the actual observed real-world temperature datasets (from satellites) and those temperature predictions from computer climate models.

While these differences may not prove the allegations against the Climategate scientists, they do confirm us about one thing: the computer climate models exaggerate the future warming rate due to their high sensitivity to carbon dioxide emissions. As a result, the models continue to show an excessive and unreal warming rate for future decades.

Despite plenty of evidence, the IPCC continues to use these faulty model predictions to inform the public and policymakers about future changes in temperature.

A steady stream of scientific studies has documented the evidence for lack of dangerous warming—IPCC’s level of warming based on fifth- and sixth-generation (CMIP5 and CMIP6) models and the apparent absence of climate-induced ecological collapse.

In 2020 alone, over 400 peer-reviewed scientific papers took up a skeptical position on climate alarmism. These papers—and hundreds from previous years—address various issues related to climate change, including problems with climate change observation, climate reconstructions, lack of anthropogenic/CO2 signal in sea-level rise, natural mechanisms that drive climate change (solar influence on climate, ocean circulations, cloud climate influence, ice sheet melting in high geothermal heat flux areas), hydrological trends that do not follow modeled expectations, the fact that corals thrive in warm, high-CO2 environments, elevated CO2 and higher crop yields, no increasing trends in intense hurricanes and drought frequency, the myth of mass extinctions due to global cooling, etc.


In simple words, Gore misled the world and promoted falsehood as science, and he continues to do so while profiting from a renewable industry that is sold as the cure for global warming. Yet, he himself generates carbon dioxide emissions and many times higher than an average family’s.

So, not only are the predictions of models are wrong, but also the interpretations of climate data and the propaganda of a climate doomsday were also wrong.


So, I am a climate realist. I acknowledge that there has been a gradual increase in global average temperature since the end of the Little Ice Age in the 17th century. I acknowledge that climate change can happen in both ways—warming and cooling. I do understand that anthropogenic CO2 emissions and other greenhouse gases could have positively contributed to the warming from mid-20th century onwards.

I also acknowledge that warming and the increased atmospheric carbon dioxide that has contributed to it have actually helped society. The current atmospheric carbon dioxide concentration, nearly 50 percent higher than in the 17th century, and the warming—which has occurred chiefly in winter, in higher latitudes and altitudes, and at night, thus raising cold temperatures but with little effect on hot temperatures—have actually resulted in optimal conditions for global plant growth, thus aiding in the flourishing of the agricultural sector.


The models do not know the future, and neither do the Climategate scientists. But an exaggerated view of future warming provides the ideal background for anti-carbon-based fuels policies that will undermine the economic well-being of every society in the world. We must not allow that.

Be a climate realist.

Comment: I am a twin with this guy. A knew all the material presented long ago.
