Here's how much the balance has changed: For the last 400,000 years, the amount of carbon dioxide in the atmosphere fluctuated between 200 and 280 parts per million, according to NASA.

Within a human lifetime, concentrations of CO2 in Earth's atmosphere could reach levels associated with 19 "mass extinctions" that have taken place in the last 534 million years, new research ...
