I will briefly describe the biological impacts too\, focusing on the impending collapse of coral reef ecosystems\, because of what this tells us about the onset of tipping points\, and to introduce the concept of ‘wobble and tip’. Then I will focus the rest of the climate part of this talk on the cryosphere\, especially the Greenland ice sheet\, to develop the concept of tipping points in more detail. In particular\, I will argue that the Greenland ice sheet has already passed two major tippi ng points\, one associated with global ocean warming\, and the other associ ated with global warming of the atmosphere. I will then shift gears\, and s eek some grounds for optimism! And that is the extremely rapid growth of re newable energy. I will present an argument as to why that growth will conti nue. I will conclude that the major barriers to saving our climate system\, nature\, society as we know it\, and the global economy\, are mostly polit ical in nature\, and not technical. One key question is\, will the short te rm and narrow interests of the fossil fuel industry be allowed to destroy t he prospects of the far wider economy? The other key question is\, what do you plan to do about it?
