Message of CLINTEL to National Politicians and World Leaders at COP26 (pdf)

  1. Hard facts show that global warming is NOT catastrophic, and therefore, there is NO climate crisis. Stop your fear-mongering messages. Fear leads always to wrong decisions and above all, it destroys the minds of our youth. Instead, inspire them with a positive outlook!
  2. The big climate picture tells us that we are slowly moving via ups and downs to the next ice age. The recovery from the Little Ice Age has been very beneficial for mankind and nature. Enjoy today’s relatively benign climate! Sometime in the future we will again move to a colder phase and ultimately into the next ice age.
  3. The big climate picture also tells us that extreme weather, consisting of heat waves and cold fronts, droughts and floods, hurricanes and blizzards, etc. is an integral part of the Earth’s climate. Stop cherry-picking weather events that suit your fear-mongering agenda!
  4. Already for many decades, real-world observations show that IPCC’s climate models seriously misrepresent unbiased science. The reality is that changes in the CO2 emissions have a negligible impact on the Earth’s weather and climate. The reality is also that sea level rise has been stable and small for centuries.
  5. CO2 is not a pollutant. It is essential to all life on Earth. Photosynthesis is a blessing. More CO2 is beneficial for nature, greening the Earth. It also benefits agriculture, increasing crop yields worldwide (see Figure 1), enabling us to address global hunger.
  6. Please, stop slavishly following the Paris Climate Accord of 2015. It is fear-based and will only impoverish world nations. Instead, develop concrete climate adaptation plans, in collaboration with the regions. Global mitigation policies cost an exorbitant amount of money and they have never saved one life. National adaptation plans work, whatever the causes of climate change may be (see Figure 2).
  7. Wind- and solar energy can play only a small role in the energy transition. Use clean fossil fuel power for the increasing energy needs, particular in developing countries. Meanwhile, cooperate worldwide to develop the nuclear power plants of the future, together with new storage and transportation technologies. It will result in prosperity for all.

Figure 1: CO2 is not a pollutant. It is essential to all life on Earth. More CO2 is beneficial for nature, greening the Earth. It also benefits agriculture, increasing crop yields worldwide, enabling us to address global hunger

Figure 2:  Climate related deaths have declined over 95% in the past century due to increasing prosperity! Mitigation policies do the opposite as they destroy wealth. Investment in adaptation always works, whatever the causes of climate change may be.
