Decarbonization by 2050
The document discusses a roadmap for global decarbonization by 2050, highlighting the significant contributions of major fossil fuel-producing countries to climate change. It outlines five key pillars for achieving this goal, including zero-carbon electricity and sustainable land use, and emphasizes the need for international collaboration, especially led by Europe. Additionally, it addresses the challenges of decarbonization in various sectors and the vulnerability of Asia to climate impacts, while promoting potential public health benefits from reduced air pollution.

Editor's Notes
- #3 The principal climate metric is global temperature, and it is a useful metric. Seems that global warming has been almost a linear warming since 1970, despite UN agreements that we need to slow the warming
- #4 However, Earth is now warmer than any time in the current interglacial period, the Holocene, the period in which civilization developed. And there is more warming in the pipeline.
- #6 That would be a problem, if we let it happen. Cities become dysfunctional long before they are totally under water. These are all of the world’s largest cities. More than half are on coastlines.
- #7 In fact, the warming seems to be accelerating.
- #11 These things are happening. Dry regions are having more extreme events. Here are fires in Greece.
- #12 More images from the fires in Greece.
- #13 Fires have always occurred, but despite massive efforts to extinguish fires in the U.S., the area burned is increasing.
- #17 Human-made climate change is proportional to cumulative emissions. The U.S., the UK and Germany are much more responsible for climate change than the developing countries. We in the West burned most of the carbon budget allowed, if we want to avoid losing coastal cities. But we are all in the same boat. We must cooperate to move the world to clean energies.
