Scientists are scrambling to find a way to slow down or stop global warming. Many are tackling the problem by looking for ways to manage carbon dioxide, also known as CO2. Released by the burning of fossil fuels — such as oil, natural gas and coal — this pollutant traps heat near the planet’s surface. Some engineers propose injecting CO2 underground to keep it out of the atmosphere. Like a global Band-Aid, this could put off hot-planet problems for a while. But new data suggest it also might ...
