Climate Change Minister James Shaw, National spokesperson Todd Muller and entourage have attended the Paris Climate treaty held in Katowice, Poland.

Reportedly, 38,000 people attended this conference. How did they get there? Did they walk, swim, kayak? No, of course not! They flew – at taxpayers' expense – or used diesel trains. They stayed in centrally-heated hotels and conference centres, and used their laptops and smartphones and taxi cabs to communicate.

Where do these alarmists think lithium, the heart of batteries, copper and carbon to build wind generators come from? Sure doesn't grow on trees. It comes out of the ground.

Poland is the largest hard coal producer in Europe and has the ninth largest coal production in the world at 131.1 million tonnes – and the green/left alarmists haven't got the courage to hold their conference in an undeveloped country without all the mod-cons.

Why didn't they used modern technology, such as skype or global teleconferencing?
