by Bryan Walker February 7, 2012

We have the technology, but…

by Bryan Walker September 30, 2011

“One word sums up the attitude of engineers towards climate change: frustration.” That’s Colin Brown, director of engineering at the UK’s Institution of Mechanical Engineers, writing in the latest New Scientist. Political inertia combines with continuing noise from the vocal minority of sceptics to mean that we are doing woefully little to prevent the worsening [...]
