What is the right diagnosis?

April 22, 2014 is Earth Day, and I will be giving a talk at an Earth Day event in Ann Arbor, Michigan. I was asked to talk about the weather and if it is changing due to human-caused climate change. Yes it is. There are some safe conclusions about climate change due to increasing carbon dioxide: the planet is warming, ice is melting, sea level is rising and the weather is changing. All of these changes are occurring and ...

I was reading this article, Green Energy Draws Investment Worldwide, which reports on the United Nations' Global Trends in Renewable Energy Investments 2014. The article documents that global investments in renewable energy dropped in 2013, but also notes that China now exceeds Europe in renewable energy investments. Part of the reason for reduced investment in renewable energy was due to the declining price of...

No Energy Policy and Even Less Climate Policy

This week I gave a lecture on current energy use. Of the lectures I give, those on current energy use and trends are the ones I have to change the most from year to year. I remember that as a child in 1961 my father gave me a world atlas that stated that the U.S. had the world’s greatest petroleum reserves, and that all was quite rosy for the future. That didn’t turn out so well. If I look at the past ...

Enjoying the Cold

Enjoying the Cold

In the last couple of weeks several people have sent me this comic, Cold, from xkcd. The cartoon draws from the work at Climate Central, an organization that is doing excellent work with data and communication about climate, weather and climate change. The point of the cartoon is that if you look back at the weather of not so long along ago, we saw cold temperatures like we have seen in the U.S. this...
