Could precisely engineered nanoparticles provide a novel geoengineering tool?

by Andrew Maynard September 13, 2010

This is an extremely quick and dirty blog post, as I really need to be somewhere else.  But while traveling to the World Economic Forum meeting in China today, I came across a new paper that piques my interest. The paper is by David Keith at the University of Calgary (published in the Proceedings of [...]

Owning the carbon cycle

by Andrew Maynard January 28, 2010

This evening I was invited to talk to a group of industry leaders on alternative solutions to the “carbon” problem at the World Economic Forum Annual Meeting in Davos.  The brief was to be one of three “firestarters” – a bit of a dangerous one if you ask me.  Given the informal setting (this was [...]

Ten emerging technology trends to watch over the next decade

by Andrew Maynard 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 [...]

Completing the circle: Coupling science & technology outputs to inputs

by Andrew Maynard December 7, 2009

Part 9 of a series on rethinking science and technology for the 21st century Writing about completing the circle of science and technology policy at the start of the Copenhagen climate summit seems particularly fitting.  Although the climate change context was far from my mind when I started this series, it stands as a stark [...]

Geoengineering options: Balancing effectiveness and safety

by Andrew Maynard 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 [...]

Confluence: Where communication, coupling and control collide

by Andrew Maynard June 26, 2009

Part 7 of a series on rethinking science and technology for the 21st century Yesterday, I listened to respected economists discussing geoengineering; gave a Skype interview on nanotechnology from the comfort of my own home; and watched as reactions to Michael Jackson’s death spread through virtual web-based communities.  Twenty years ago, when Jackson was at [...]

Geoengineering: Are we grown up enough to handle it?

by Andrew Maynard 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 [...]

Steve Chu’s White Revolution

by Andrew Maynard 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 Energy Steve [...]

Geoengineering goes mainstream

by Andrew Maynard 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 [...]

Science, technology and the three “C’s:” Communication, Coupling and Control

by Andrew Maynard March 19, 2009

Part 1 of a series on rethinking science and technology for the 21st century We live in a crowded, science and technology-dependent word.  And things aren’t getting any better!  The global population is currently around 6.8 billion.  Over the next four years it’s projected to grow to over 7 billion.  And by 2050, the US [...]

Rethinking science and technology for the 21st century

by Andrew Maynard March 13, 2009

Like it or not, society is dependent on science and technology.  The only way we can cram 6 billion people plus onto the earth and use resources at the rate we do, is through the support of scientific discovery and technology innovation.  Take our technology-based infrastructure away and civilization as we know it would collapse.

A 2020 Science Taster

by Andrew Maynard February 19, 2009

Given the recent surge in 2020science readers (thanks to Lon S. Cohen at Mashable), I thought it about time I did a short retrospective—a taster for the type of stuff you can expect to read here.  So here are five pieces from the past year that cover everything from nanotechnology to synthetic biology, and ethics [...]

Geoengineering: Does it need a dose of geoethics?

by Andrew Maynard 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 [...]
