Anti-climate change consensus: Italian scientists say global warming is not man-made

Leading Italian scientists published a letter with nearly 100 signatories refuting the supposed consensus on anthropogenic climate change.
A group of 83 renowned Italian scientists published a letter on January 11 assuring that scientific evidence shows that climate change and global warming exist, but it has no basis in human action, rather that significant temperature changes are natural processes.
In recent decades, it was found that the Earth’s surface has increased by approximately 0.9°C from 1850 to date, and it was hypothesized that this is abnormal and is due to human activities, particularly excessive emissions of CO2 from the use of fossil fuels.

However, the anthropogenic origin of global warming is an unproven conjecture, deduced only from certain climate models, that is, from complex computer programs that estimate certain patterns of how the Earth’s temperature should evolve, called general circulation models.
There are equally valid models that prove the opposite; that much of the Earth’s temperature rise is explained by natural, not human, phenomena.
To date, there is no evidence that allows choosing one model over the other, say the signing scientists.
“The anthropogenic responsibility for observed climate change in the last century is therefore grossly exaggerated and catastrophic forecasts are unrealistic,” they conclude.
