John Holdren, Science Advior to President Barack Obama: The essence of the energy-climate challenge: • Without energy there is no economy, • Without climate there is no environment, • Without economy and environment there is no material well-being, no civil society, no personal or national security The essence of the challenge is that the world has long been getting most of the energy its economies need in ways that are now seriously disrupting the climate its environment needs.
John Holdren was President Barack Obama's Science Advisor: In the 1970s he talked about serious man-made global cooling. Since then, he talks about serious man-made global warming. In 2016 they issued a document saying that they would/could reverse climate change. If the climate gets warmer, they would cool it down (by stopping use of fossil fuels) and if the climate gets cooler, they would warm it up. Nothing close to this has ever been done. Here, he talks about the perversity of scientists discussing the "settled science" of man-made global warming. This has tremendous consequences for the global economy and well being of people everywhere. May the red team - blue team man-made global warming discussions begin.
John Holdren, Science Advisor to President Barack Obama: “The world needs ultimately to completely decarbonize,” We know without any doubt that the climate is already changing in ways that are not explainable by natural influences and that are precisely explainable as a consequence of the heat trapping gases that we have added to the atmosphere by fossil fuel burning and deforestation. We know that damaging impacts are already occurring all around the world. John Holdren, Think about what Holdren says: "World Must Act Now to Reverse Climate Change" If the climate gets colder, we must heat up the planet. If the climate gets warmer, we must cool down the planet. Is this sensible, feasible????
John Holdren, Science Advisor to President Barack Obama: Climate change is a straightforward issue. “We are seeing increases in the frequency and intensity of a wide variety of weather extremes, again, through mechanisms and in patterns that fit the fingerprint of the human influence on climate.” This belief has led Dr. Holdren, over the course of his career, to work to drive the nation’s shift toward clean energy policies and sustainable development, and boost cooperation with nations such as India and China on energy issues. That mainly meant using less energy, using a lot less fossil fuels, advocacy for wind and solar and hardly anything for nuclear. He sometimes rides a bicycle to work.
