A defense of geoengineering
How much should Earth’s environment be manipulated by technologies to reduce the risks of global warming and other impacts of climate change? Geoengineering efforts like the carbon capture system developed Fulton Schools Professor Klaus Lackner (pictured) and his research team are raising the question. Lackner’s Center for Negative Carbon Emissions has developed “mechanical trees” that can absorb and sequester the detrimental greenhouse gas. Some argue such systems won’t stop activities like burning fossil fuels that cause the buildup of carbon dioxide in the atmosphere. But others contend we can’t afford to dismiss technologies that can help put nature back on course.
