Every planet in the universe with a climate, changed from their beginning. Most have no humans living on them to cause the changes. Our climate has changed ever since the earth was created. All known life on earth requires carbon to live. Carbon is not poison; in fact, carbon filters are used to purify and detoxify many processes. All life on earth requires a greenhouse to live. Proof, just check Mercury, Venus, Mars etc. they don’t have greenhouses. CO2 is only 0.04% of our atmosphere and is required so plants can produce oxygen for humans to breath. Leftists claim all problems(?) on earth are caused by humans. The only possible solution is to eliminate humans. All leftists must eliminate themselves first. When they’re gone, the earth will be safe for conservatives! If you didn’t create the earth, what makes you think you can save the earth? Earth was here millions of years before humans and will be here millions of years after humans are gone. Far too much hubris and ignorance!
