1. Climate Change Is Just Natural Variation
While Earth’s climate has changed throughout history, today’s warming is unprecedented in speed and scale.
Paleoclimate records—ice cores, tree rings, and sediment layers—show that recent decades have seen a sharper rise in temperatures than at any point in the past 800,000 years.
The scientific consensus is clear: human activities, especially burning fossil fuels, are the primary drivers behind this rapid change—not natural cycles alone.
