Mechanical engineer Jennifer Wade is leading two federally funded projects that are addressing the critical question of how to remove greenhouse gases from the atmosphere, thus slowing the devastating effects of global climate change. It’s part of a national effort called the Carbon Negative Earthshot: Being able to remove carbon at $100 a ton at a scale of a million tons per year. That’s a difficult task, Wade says, but it’s not an insurmountable one.
