Climate change sceptic admits temperature data shows warming

Richard Muller of Lawrence Berkeley National Laboratory in California has gained a solid scientific reputation for his work in astrophysics and particle physics. He also has a reputation for not being afraid of wading into public policy debate. Although not a climate scientist, Muller has published peer reviewed papers that questioned elements of historical temperature data of climate change and is therefore considered a ‘credible’ sceptic. An expert team was

China bans incandescent light bulbs

Even those without
