more on climate change

The Union of Concerned Scientists has a global warming FAQ. This is a good resource where one can learn more about the science of global warming and the impact of the human economic system on climate change.

I believe that the impact of climate change, and whatever remediation activities that we might undertake, will be a major factor in defining the landscape of the 21st century. Learning as much as we can about this topic will help us make informed decisions about policy options in the future.

one cubic mile

IEEE Spectrum has a fascinating but sobering analysis of energy use and alternatives. Roughly, the world currently uses about one cubic mile of oil per year. As an additional ironic note, I'm typing this at exactly the same time the local company is delivering oil to this house, as we ran out last night unexpectedly.

climate change

Several events and related articles in the press recently provide further insight into global climate change and how we learn about it and think about it.

Cathy Young in the Boston Globe offers this article on bringing common sense into the political debate.


NASA Watch provides a collection of articles about funding risks for Earth Observation Satellites in this post: Earth Observation Satellite Cuts Examined.

And the New York Times has a great piece on The Warming of Greenland - uncovering a new island.

It seems to me that Cathy is right - we need common sense, and we need that common sense informed by as much relevant scientific data as possible. Seems like this is the worst possible time to take the risk of having less data provided by earth-observing satellites.
