The wrong road to take - Hot Topic

Jan 19, 2012

It’s difficult not to become repetitive when blogging about climate change. The basic science is well-established.

An interesting-looking series of posts has begun on the climate ethics blog of Penn State’s Rock Ethics Institute.

Politics of Climate Justice - Hot Topic

Dec 28, 2011

I warm to any writer who identifies the solution to climate change in the simple terms employed by Patrick Bond in his recent book Politics of Climate Justice: Paralysis Above, Movement Below: leave fossil fuels in the soil, halt deforestation, transform our economies so that renewable energy, public transport and low-carbon systems replace those currently [...]
