The Agricultural Research Service produced scanning electron microscope images of what frost would look like on Mars. And it isn't water crystals that form this frost — it's carbon dioxide. More »

Climate change might turn lizards into geniuses, but fish won't be quite so lucky. All the billions of tons of carbon dioxide that enters the oceans each year is like alcohol for fish, turning them into risk-taking idiots. More »

Most climate change predictions have only examined the next hundred years. But now a new, even more long-term model suggests that temperatures could rise as much as ten degrees Celsius by 2300 — creating conditions not seen for 34 million years. More »

All around the Martian south pole, there are huge deposits of frozen carbon dioxide, better known as dry ice. In this image by NASA's Mars Reconaissance Orbiter, we can see huge dry ice pits... and the mysterious walls that encircle them. More »

Generally speaking, poop isn't pleasant, but it also isn't exactly lethal. But every year jellyfish unleash bowel movements so deadly that they can destroy entire marine ecosystems. A little odor doesn't seem so bad all of a sudden, does it? More »

In the 1200s, Genghis Khan and the Mongolian army built an empire that stretched from the Pacific Ocean to central Europe, ruling over a fifth of all land on Earth and over 100 million people. And all that conquering reshaped the Earth, reducing carbon dioxide levels enough to offset a year's worth of gasoline usage today. More »

It's straight out of 1950s science fiction: an entire country connected by food-transporting pipelines, sending baked beans and smoked kippers sailing between London and Liverpool at 60 miles per hour. And it's arguably more sensible than what we're already doing. More »

Reducing our carbon footprints definitely won't be easy. Indeed, 20% of all carbon dioxide emissions come from people eating - and digesting. More »

Mars's thin atmosphere is now about 95% carbon dioxide, but when the planet's atmosphere is only 1/200th the size of Earth's, that doesn't mean very much. Now deeply buried minerals reveal Mars once had nearly Earth-like levels of carbon dioxide. More »

There's an igneous rock called peridotite that can sponge carbon dioxide out of the atmosphere and store it in mineral form. Weirdly, almost no one is talking about it. More »

Earlier this week we reported on the magnetic anomaly map of the world, and now there is evidence of a more pressing concern: carbon dioxide. Don't believe me? Consult the details of a recent collaboration between NASA and Caltech - Carbon dioxide rides about the world on warm atmospheric belts to threaten the ones you love. If you have any decency you'll click through and assuage the damage with us. More »
