Allan MacRae sums up the term "Global warming better than i can. "The current usage of the term “climate change” is vague and the definition is routinely changed in the literature, such that it has become a non-falsifiable hypothesis. It is therefore non-scientific nonsense. “A theory that is not refutable by any conceivable event is non-scientific.” – Karl Popper Climate has always changed. Current climate is not unusual and is beneficial to humanity and the environment. Earth is in a ~10,000 year warm period during a ~100,000 year cycle of global ice ages. The term “catastrophic human-made global warming” is a falsifiable hypothesis, and it was falsified decades ago when fossil fuel combustion and atmospheric CO2 increased sharply after ~1940, while global temperature cooled from ~1945 to ~1977. Also, there is no credible evidence that weather is becoming more chaotic – both hurricanes and tornadoes are at multi-decade low levels of activity." https://www.thegwpf.org/content/uploads/2013/11/Khandekar-Extreme-Weather.pdf "Even if all the observed global warming is ascribed to increasing atmospheric CO2, the calculated maximum climate sensitivity to a hypothetical doubling of atmospheric CO2 is only about 1 degree C, which is not enough to produce dangerous global warming." https://wattsupwiththat.files.wordpress.com/2017/11/2017_christy_mcnider-1.pdf https://journals.ametsoc.org/doi/10.1175/JCLI-D-17-0667.1 I believe "climate crisis" is the new buzz word.
