FR And let me preface this by saying I certainly don't discount the impact modern man has had on the environment, or added to climate changes globally or regionally. Every dam we've built, every marshland we've decimated, every road constructed, and every garbage truck sent to the landfill has its consequences. Bosco has/had a sarcastic line in his signature I happen to agree with. Paraphrasing here: 200+ years of hurricanes, but this last one was because of climate change. The Earth has undergone many changes in its 4.5billion years. Science can't always explain them. But man has had little impact on any before now. It would be good to control what we can, limit our footprints on the planet as a whole, and avoid pollution as much as possible. But I don't believe everything can be blamed on modern man with our industry, technology, and waste. Science lacks a control in this experiment; a planet exactly like Earth, without industry and aerosol spray cans. And since temperatures on our planet ebb and flow quite regularly, we may have periods of stability, but absolutely no certainty of it. Though none of us were around to see it, we're not all that far removed from the 'Little Ice Age' from the 1400's to about 1850. And our true Ice Age was only 11,500 years ago. It was hotter on Earth than it is now when dinosaurs roamed the planet. And much colder when wooly mammoths and sabre toothed tigers were around. Lifeforms have no need to evolve or adapt if there are no changes to force it. Science can't tell us what our temperatures are supposed to be, because there is no way to know. Anything we have to say is anecdotal at best, similar to 'uphill, in the snow, both ways'. We have El Niños and La Niñas, droughts and flash floods, blizzards, hurricanes, tsunamis, earthquakes, wild fires, changing seasons 4 times a year... we can't explain away the root causes of many of these by blaming man. https://www.climate.gov/news-features/climate-qa/whats-hottest-earths-ever-been Part 2
