But today, carbon dioxide levels are skyrocketing as humans burn long-buried fossil fuels. “CO2 in the atmosphere has gone up 100 ppm in my lifetime,” said Kathleen Benison. a geologist at West Virginia University who researches past climates. “That’s incredibly fast geologically.” “...
As levels of carbon dioxide - CO2 - in the atmosphere have been rising in recent decades, Earth has been warming. That’s because as a greenhouse gas, CO2 traps heat in Earth’s atmosphere. That warming is one symptom of climate change. And it has the potential to affect food in many...

Global sea levels during the Pliocene were thought to be a whopping 25 meters (82 feet) higher than today, if not higher. Devastating effects High levels of CO2 in the atmosphere – caused by humans burning fossil fuels and cutting down forests – prevent the Earth’s natural cooling ...
