Tim Flannery is one of the world's leading writer-scientists and thinkers and an internationally acclaimed explorer and environmentalist. Sir David Attenborough described him as being in the league of all-time great explorers such as David Livingstone. Tim has shown that human activity is drastically altering Earth's climate and that these changes will have a devastating effect of life on this planet. He wants to mobilise the social and political will to address this problem before it's too late. That's why he wrote an important and provocative book The Weather Makers, which debuted on the New York Times bestseller list and which also won this year's NSW Premier's Book of the Year award. Tim helps us understand the predicament we face, carefully laying out the science and showing us the likely effects of human-induced climate change. But he also offers us hope of a solution to stop and ultimately reverse this trend.
