3. The Climate Has Always Changed—Humans Aren’t to Blame

It’s true that Earth’s climate has shifted over millions of years due to natural factors like volcanic eruptions and changes in solar activity.
However, the current spike in global temperatures is tightly linked to a dramatic rise in atmospheric greenhouse gases since the Industrial Revolution.
Unlike ancient shifts, today’s changes are much faster and directly traceable to human activities—especially burning coal, oil, and gas—according to long-term carbon dioxide records.
