Carbon dioxide makes up less than one-twentieth of 1% of Earth's atmosphere. How does this relatively scarce gas control Earth's thermostat?
As our planet warms, the number of air-conditioning units worldwide is expected to triple by 2050 – yet their use drives climate change. So how can we break the cycle?
This hot, acidic neighbor with its surface veiled in thick clouds hasn't benefited from the attention showered on Mars and the Moon. But Venus may offer insights into the fate of the Earth.
It helps if you imagine the ground here on Earth as a big heater. It keeps us warm, and if you move away from the heater you feel cold.
The Earth’s past shows the key role of CO₂ on climate for 4.45 billion years, and how human industrial activity has disrupted its cycle at an unprecedented rate over the past 160 years.
Fourier's discoveries can still be felt in modern-day radiology, climate science and physics.
The 2016 bleaching on the Great Barrier Reef was the worst on record. Now a new analysis points the finger squarely at human-induced warming, and warns that the entire reef's future is at stake.
By capturing Arctic methane emissions, the gas industry could join the fight against climate change.
The planet is more similar to Earth than any other – except when it comes to supporting life.
The sun is more powerful today than when we last had similar levels of carbon in the atmosphere.
Some atomic ratio detective work on our solar system neighbors tells us a lot about their watery pasts. That Venus and Mars are mostly dry now could be a cautionary tale for us on the Blue Planet.
