Let's be brutally honest: the gullible and very stupid have been brainwashed to believe the propaganda that human CO2 emissions have a significant climate change impact resulting in severe weather events.
As this chart from a peer-reviewed research journal indicates, since ancient times, the climate has been in a constant state of change causing extremely low and high weather events, regardless of the atmospheric CO2 levels.
This group of researchers analyzed an almost 5 century record of streamflow volumes in the Southern Tibetan Plateau. Streamflow volume is driven by precipitation and weather extremes in either direction would be identified with this type of analysis.
"As seen there, perhaps the most striking feature of the record is the short eight year decline in streamflow from the highest value (487.1 m3 s-1) in 1871 to the lowest value (205.4 m3 s-1) of the nearly five-century-long record, which sharp transition was a completely natural occurrence and could not have been due to CO2 (because the vast bulk of the modern CO2 rise has occurred over the past six decades). Aside from the above-mentioned event, the record displays considerable variability at multiple time scales, yet there is no obvious trend or indication that there is anything unusual, unnatural or unprecedented in recent years of the streamflow record that would indicate rising atmospheric CO2 is having an effect....Further analyses indicate these periodicities are likely natural in origin; they correspond well with and are likely significantly driven by ENSO, the Asian summer monsoon, and other large-scale climate circulation features."
Additional examples of research indicating little, if any, climate change attributes related to CO2 levels.
