Hasn't the Earth's climate changed before?

• The Earth's climate is always changing, but human-caused climate change today is unlike any other period in our planet's history. The Earth's climate and atmosphere have changed drastically over the last 4.5 billion years

• Earth's climate has changed throughout history. Just in the last 800,000 years, there have been eight cycles of ice ages and warmer periods, with the end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization.

• Earth's climate has changed many times. For example, fossils from the Cretaceous period (144 to 65 million years ago) show that Earth was much warmer than it is today. Fossilized plants and animals that normally live in warm environments have been found at much higher latitudes than they could survive at today.
