It's no secret that Victoria's Secret model Gisele Bündchen loves the earth. The Brazilian supermodel is a U.N. advocate for environmental awareness, has a green blog, and just started an eco-friendly skincare line. Recently she and Patriots beau Tom Brady (looking slightly like a '70s Ken doll) appeared in some short videos to raise awareness about Earth Hour, when people worldwide flick off lights for an hour to raise awareness about climate change. (Coincidence that it saves ...

In my previous post, I asked the question: Do recent weather events and news reports have you reconsidering global warming? Rather than answering the question directly, I asked the broader question: How do we know what we think we know? So, continuing the thread of skeptical inquiry, let’s turn a critical mind toward climate science.

The basic science behind the greenhouse effect is both long-established and non-controversial. First, we know that carbon dioxide...

Global warming is one of the greatest challenges of our generation. It's going to require new ways of thinking to incorporate cleaner sources of energy in our energy generation, to improve our energy efficiency, and to reduce our carbon footprint. We are already seeing innovations in this space in energy generation, distribution, efficiency, and storage. From more efficient solar panels and wind turbines, to a smart grid transforming how we manage energy distribution, to home energy management solutions helping ...

One of the most-cited reasons for using tools like Microsoft Hohm – along with saving money – is to help reduce carbon emissions and thus reduce the threat of global warming. Obviously saving energy and money is a worthwhile goal. But do recent weather events and news reports have you reconsidering global warming?

Scientific research is supposed to promote skeptical empiricism – “Show me the numbers!” Or, to quote W. Edwards Deming, physicist and quality improvement pioneer, “In God we ...

The Wall Street Journal and Time Magazine posted articles on how Boulder, CO, a relatively progressive environmental city, is trying to stop their citizens from being armchair activists.

“Since 2006, Boulder has subsidized about 750 home energy audits. Even after the subsidy, the audits cost each homeowner up to $200, so only the most committed signed up. Still, follow-up surveys found half didn't implement even the simplest recommendations, despite incentives such as discounts on energy-efficient bulbs and rebates for attic ...
