Chilly in Baltimore: Energy Efficiency and Wind Power

I heard an interesting story on NPR today about “district cooling” in which a company in Baltimore uses ice to produce chilled water, which is transported to a number of building in the city for supplemental cooling.  What really struck me as cool about this (sorry about the pun) is the fact that this system …

Success in Restoring the Ozone Layer, Mixed News for Climate Change

The good news is that the ozone layer is recovering.  The reason it’s recovering is because the international community agreed — in the Montreal Protocol — to phase out harmful chemicals that were depleting the layer and causing huge holes in it.  That’s the conclusion of 300 scientists who recently issued a  “Scientific Assessment of Ozone Depletion …

The Myth of SB 375

Today is a big day for SB 375, California’s much-heralded land use and transportation law. The Air Resources Board is setting greenhouse gas emissions targets for each metropolitan region covered by the law.

Prop 23 and PG&E: Setting the Record Straight

The California Jobs Initiative is spreading a highly misleading story about PG&E’s opposition to Prop 23, the ballot measure to suspend California’s keystone climate legislation (AB 32).  The story appears in an email that they’ve circulated widely.  To make it easy to understand, I’m leaving the truthful parts of their story in black and putting …
