Investors and scientists are restoring a 23-square-mile tract of peatland in North Carolina to curb emissions of climate-warming carbon dioxide and regenerate native habitat. Ditches have drained water from thousands of years accumulated peat, leaving the site vulnerable to drought and wildfire and unleashing huge volumes of carbon dioxide. One-third of global carbon is stored in saturated peatlands, more than all forests combined. But that reverses when peatlands are damaged. Pantheon Regeneration plans to restore the water table to curb emissions, then sell carbon credits to help fund its goal of preserving a million acres of peatland from Virginia to Florida.

An enduring conspiracy theory has resurfaced on social media after a 7.4 magnitude earthquake hit western Colombia on Monday, with users blaming a research program in Alaska for the disaster. Posts falsely claim that the earthquake, which has killed at least 270 people and left widespread damage in its wake, was caused by the High-frequency Active Auroral Research Program, or HAARP, which studies the properties and behavior of the upper atmosphere. But the earthquake was actually caused by natural movements in the Earth’s crust. Experts say it had nothing to do with human activities.
