“The earth is dying—and it’s your fault!” That’s the message we’ve heard for decades from the media and many politicians. But is it true? Is climate change the biggest threat to life on earth?

Well, consider that centuries ago, the global temperature was declining, then about four hundred years ago, it started slowly rising again. So, it’s possible temperature variations are normal—maybe due to cycles on the sun’s surface.

Also, carbon dioxide—the gas blamed for climate change—isn’t the most important greenhouse gas. Water vapor and clouds are! Man-made CO₂ only makes up a fraction of greenhouse gas.

So why the hysteria? That’s for tomorrow!
