๐ŸšจA new study has revealed for the first time that ancient carbon, stored in landscapes for thousands of years or more, can find its way back to the atmosphere as COโ‚‚ is released from the surfaces of rivers at a rate of 1.2 billion tonnes per year.

Details๐Ÿงต1/8 Image
2/ To understand the true source of river COโ‚‚, researchers compiled a global dataset of 1,195 radiocarbon measurements of dissolved inorganic carbon (DIC), COโ‚‚ & CHโ‚„ from rivers & streams.

This let them determine whether the emitted carbon was modernโ€”or much older. Image
3/ Using radiocarbon signatures (ยนโดC), they found that 59% of river COโ‚‚ emissions come from "old" Cโ€”millennia-old soil carbon & even petrogenic carbon (rock-derived, >55,000 years old)

Only ~41% came from recent biological sources like plants & microbes (decadal carbon). Image

๐ŸšจA NEW study explores a theoretical #geoengineering approach to combat global warming โ€” by altering Earthโ€™s orbit.

Simulations suggest that shifting Earth ~5.8% farther from the Sun could cool the planet by roughly 7K, effectively offsetting projected warming.

DETAILS๐Ÿงต1/10
2/ Climate models suggest global temperatures could rise by 7K by 2100, driven by greenhouse gas emissions.

This study asks: what if, instead of changing the atmosphere, we changed our position in space?
Specifically: increase Earthโ€™s orbital radius.
3/ Basically, the paper builds on the science of Milankovitch cycles which is slow, natural variations in Earthโ€™s orbit and tilt that have triggered past ice ages.

These cycles show that even slight orbital changes can dramatically affect climate. Image
