Yes, as I understand it you are absolutely right about natural climate variation. And the Little Ice Age affected North America too. (I believe that most or all of our Washington glaciers are from that time, not from the "big" ices ages 10s of thousands of years ago.)Walla Walla Dawg II wrote: ↑Sun Jul 11, 2021 2:00 pmWe need to protect this planet we call home. It falls into the same category as protecting the home we live in. That doesn't mean we need to be so "Nazi" about it. A very practical requirements will keep it good.
In the 1970's it was "Global Cooling".
In the 1990's it was "Global Warming".
Around 2005 they relabeled it again because too many people debunked it to "Climate Change".
Climate change has been happening for 1000's of years. The Sahara was once a lush beautiful area.....its now a desert. That wasn't caused by cow farts.
In the mid-evil years, Europe had a mini-ice age:

This planet can be affected by nature and humans. Cows, uncontrolled, will decimate an area by eating to the ground, thus causing erosion when the rains hit. Nature can throw another asteroid at us and wipe out the planet, but given time it will recover.
As stated previously, what is anyone doing about China's o2 outputs to the environment? They don't see to be worried. Neither does Russia, India or many of the other Asian countries. Is that because the Asian countries are mostly dictators and communist so they don't have to worry about gaining money and power. I the need for a disaster only an American and European concept, or is it about the 'freedoms' we appreciate here and Europe.
But the two facts that sway me to be concerned about greenhouse gasses: [1] historically, over close to a million years (measured in ice core samples in Greenland, I believe), there is a VERY strong correlation between carbon dioxide concentrations and global temperature, and good evidence that the carbon dioxide concentration is the driver of temperature, [2] We now have higher CO2 levels than anytime during that 800,000 year period. Probably CO2 has not been this high since 2 million years ago, when
To me that is a good argument that we are in for increasing temperatures over at least the nexts century, and the impacts of this.trees grew near the South Pole and sea levels were 50 to 65 feet higher than today https://www.climatecentral.org/gallery/ ... on-dioxide
Not to sound harsh, but while I care about the planet, it can take care of itself. Trees in Antartica or 50 foot higher sea levels? The Earth will survive just fine. Don't worry about it. I'm concerned about the effects on people. Sea level rise displacing millions of people. Higher temperatures and longer dry summers affecting agriculture and food supplies. Etc.
