  • Making Sense of Gas vs. Coal and Climate: A Look at the Recent Paper by Tom Wigley

    The last few months have seen a flurry of academic papers investigating whether using natural gas for power generation creates more global warming than using coal for power generation.  A few have reached the startling conclusion that using gas for power is just as bad, or worse, than coal. The most recent of these is […]

But it can also dull us to solving key long term and chronic problems, especially regarding climate change. And, as with any medication, there can also be […]

  • A Cleantech Revolution in Four Easy Steps

    A recent National Academy of Sciences report notes that CO2 lasts thousands of years in the atmosphere, so if we really want to limit the damage from climate change, we’ll need to drop the world’s energy system to near-zero emissions by 2050. Yet the U.N.’s climate chief, Cristina Figueres, recently admitted: “I do not believe […]

The first issue is ground-level ozone. As a 2008 report by the UK Royal Society concluded, In […]
