Bill McKibben‘s on the New Zealand leg of his Do The Maths downunder tour, and I got the chance for a quick chat with him earlier today ((Rosie the truffle machine would like to apologise for her decision to whimper in the background.)). Bill lays out the essence of the carbon budget we have to live within if we’re to avoid roaring past 2ºC, explains the carbon finance bubble, discusses China’s approach to renewables, and why NZ should avoid exploiting its oil and coal reserves. See Bill in Dunedin tonight, and Wellington tomorrow.
