You have the dwindling of polar ice, which is the most important tipping point because it influences the rest of the planet. There's the permafrost, which is emitting methane, and fires in the boreal forests. One of the big factors here is that they could zip throughout Canada. We've seen only the start-up of the fires. There's also the Atlantic Gulf Stream, which regulates temperature; the freezing of the Northwest Passage; and the polar vortex extending over the north and influencing, in a catastrophic way, weather in the south. We've seen that in the last three or four years, as well as the rising temperature of the ocean. These are factors from these tipping points.
