The best scientists, scrutinizing atmosphere, ice, earth, and sea, say global warming is approaching a tipping point. But we still have time to keep it from reaching catastrophic levels.
Don’t expect the scarcity of fossil fuels to drive us toward alternative energy sources anytime soon: we’re getting smarter about finding and extracting oil.
Better technologies exist for extracting coal, a major source of carbon dioxide emissions. The challenge is getting people to adopt them.
The U.S. Energy Department’s fuel-recycling initiative could be a distraction from a more achievable goal: reviving today’s nuclear industry and averting some carbon emissions in the short term.
Genetically engineered organisms that more efficiently produce ethanol from cheap and abundant sources of biomass, such as agricultural waste, could make it cost competitive.
We know where we must go eventually. Why not head there now?
By investing in energy efficiency, we could vastly reduce carbon dioxide emissions and save money.
Learning to consciously alter brain activity through MRI feedback could help control pain and other disorders.
