Ten emerging technology trends to watch over the next decade

December 25, 2009

Ten years ago at the close of the 20th century, people the world over were obsessing about the millennium bug – an unanticipated glitch arising from an earlier technology.  I wonder how clear it was then that, despite this storm in what turned out to be a rather small teacup, the following decade would see [...]

Reversing the Technological Dilemma

December 17, 2009

By George Kimbrell, International Center for Technology Assessment, and the Center for Food Safety

A guest blog in the Alternative Perspectives on Technology Innovation series
Andrew asked us to write about “how technological innovation should contribute to life in the 21st century.”  Technological innovation is often blindly referred to as “progress.”  The question is — progress towards [...]

Geoengineering options: Balancing effectiveness and safety

September 1, 2009

An interesting aspect of today’s Royal Society report on geoengineering is the attempt to rate twelve potential approaches to engineering the climate by effectiveness, affordability, timeliness and safety – and to graphically compare the approaches in terms of these criteria.
While the ratings and the resulting diagram are somewhat subjective (the report’s authors call them “tentative [...]

Engaging the public on nanotechnology

July 7, 2009

Following up on my last post – Geoengineering the planet with nanotechnology ice-cream? – here’s a short video Zoe Papadopoulou and colleagues put together on The Cloud Project from my visit in June:

Geoengineering the planet with nanotechnology ice-cream?

July 5, 2009

Scientists and engineers have their moments. But it they are hard pressed to beat art students when it comes to sheer audacious creativity.
Earlier this year I received an email so intriguing I couldn’t help but follow up on it. The email was from Zoe Papadopoulou, an MA student at the Royal College of [...]

Geoengineering: Are we grown up enough to handle it?

June 14, 2009

If there’s one thing that’s guaranteed to unite global warming “denialists” on both sides of the aisle, it’s geoengineering – the intentional planet-wide manipulation of the environment.  At least, you might be left with that impression after reading the comments following a thoughtful piece in Monday’s Wall Street Journal by Jamais Cascio.

Cascio describes himself as [...]

Steve Chu’s White Revolution

May 27, 2009

It feels good to be ahead of the curve sometimes. About this time last year, I was slaving away painting my roof white – much to the bemusement of my Northern Virginia neighbors and friends. So I couldn’t help feeling just a little smug this morning as I read that US Secretary of [...]

Geoengineering goes mainstream

April 8, 2009

Twelve months ago, geoengineering seemed little more than the fancy of science fiction writers and fringe scientists.  Now, an increasing number of people are viewing it as a viable – if extreme – option for curbing global warming.  This shift was hammered home today by Dr. John Holdren, President Obama’s science advisor, in his first [...]

Geoengineering: Does it need a dose of geoethics?

January 28, 2009

It’s been a big week for geoengineering.  First there was the news that the world’s largest geoengineering experiment to date is about to start in the Southern Ocean.  Following close behind was a new study on how geoengineering projects could potentially impact global climate change, ranging from covering vast tracts of desert with a reflective [...]
