‘July 2020 Temperature Update’
‘Globally, July 2020 is estimated to have been tied with July 2019 as the warmest July since records began in 1850. The nominal difference between 2019 and 2020 is less than 0.01 °C, which is much smaller than the uncertainty on this temperature analysis, making 2019 and 2020 indistinguishable. Previously in 2020, we have also witnessed the warmest April, May, and June.’

100% Clean, Renewable Energy and Storage for Everything – by Mark Z Jacobson, Stanford University, California
‘Numerous laws – including the Green New Deal – have been proposed or passed in cities, states, and countries to transition from fossil fuels to 100% clean, renewable energy in order to address climate change, air pollution, and energy insecurity. This textbook lays out the science, technology, economics, policy, and social aspects of such transitions. It discusses the renewable electricity and heat generating technologies needed; the electricity, heat, cold, and hydrogen storage technologies required; how to keep the electric power grid stable; and how to address non-energy sources of emissions. It discusses the history of the 100% Movement, which evolved from a collaboration among scientists, cultural leaders, business people, and community leaders. Finally, it discusses current progress in transitioning to 100% renewables, and the new policies needed to complete the transition. Online course supplements include lecture slides, answers to the end-of-chapter student exercises, and a list of extra resources.’

‘…Markey was endorsed early in the race by the Sunrise Movement, a national youth-led climate action group, which cited his co-authorship of the Green New Deal and long track record of environmental advocacy. By the end of the race, polls showed that Markey had turned his deficit among young voters into a double-digit lead.’
