Ian Ross and Rita Wania on the science of climate change
Monday, June 4th, 2007
We had a big turnout for Ian and Rita who covered a massive amount of information, about the fluctuations in the earth’s climate that have existed since the beginning of life on earth, about climate models, about what we do know and what we don’t know, what is happening to biodiversity, and how the complex interactions of natural and human induced factors are affecting the climate now. They have posted their slides, and some guidance about more information sources, on this weblink. One interesting thread to the discussion concerned James Hansen’s recent calculations looking at CO2 predictions using realistic estimates of remaining oil and gas supplies. Anyhow, the evening gave us much food for thought, and left us in no doubt that reducing our use of non-renewable energy, and switching to more local ways of living and food production, are definitely the right way to be going.
