Thanks to humans, the concentration of planet-warming carbon dioxide in the atmosphere is now 50% higher than before the industrial era. These gases are raising Earth’s temperature.

Thanks to humans, the atmosphere has 50% more planet-warming carbon dioxide today than it did before the industrial era. Those gases will continue raising Earth’s temperature for years.

The Earth is a resilient planet, but people are altering it in ways that may take centuries to reverse.

Using our oceans as carbon sinks could help achieve climate goals set in the most recent IPCC report.

The growing season on the tundra is starting earlier as the planet warms, but the plants aren’t sequestering more carbon, a new study finds.

His theory, based on years of detailed climate and weather data, became known as the Callendar Effect. Today we call it global warming.

Using machines to pull CO2 from the air could help as the world tries to slow climate change. Klaus Lackner is developing new ways to cut its high costs and energy demand.

Klaus Lackner is finding new ways to cut the technology’s high costs and energy demand, and he’s about to launch the first ‘mechanical tree.’

By measuring emissions in real time, cities can take stronger action against air pollution and global warming.
