90 leading Italian scientists sign letter saying global warming is a hoax

quote:

---

However, the anthropogenic origin of global warming IS AN UNPROVEN HYPOTHESIS, deduced only from some climate models, that is complex computer programs, called General Circulation Models .

On the contrary, the scientific literature has increasingly highlighted the existence of a natural climatic variability that the models are not able to reproduce.

This natural variability explains a substantial part of global warming observed since 1850.

The anthropogenic responsibility for climate change observed in the last century is therefore UNJUSTIFIABLY EXAGGERATED and catastrophic predictions ARE NOT REALISTIC.

The climate is the most complex system on our planet, so it needs to be addressed with methods that are adequate and consistent with its level of complexity.
