Together, humans can prevent the global temperature rise from exceeding 1.5 degrees Celsius, which would change life on earth as we know it. Politics and science collide as we learn what it really means to be an advocate for the environment. The Earth is slowly heating up, and only we, as a global community, can stop it—with the knowledge behind what is happening, we can affect change. Using his PhD in Molecular Biophysics and Biochemistry from Yale and his LLM in Environmental and Natural Resources Law from the Northwestern College of Law at Lewis & Clark University, Dr. John Perona takes us on a journey into the science and politics of the climate crisis in From Knowledge to Power: Your Handbook for Climate Science and Advocacy. Perona uses the basic science of climate change, the rise of green technologies, and the political implications of climate science to present a concise guide to the critical facts regarding our climate change. He offers actionable tips for how to engage in advocacy by calling for action at every level—leaders in both science and government, community groups, and individuals like you. Perona offers a grounded, optimistic outlook for humanity, but only if we engage with science and act with knowledge.
