1) Seven Reasons We Face a Global Water Crisis
Global warming make dry areas drier ... More people & more money = more water demand ... Groundwater is being depleted ... Water infrastructure is in disrepair ... Natural infrastructure is being ignored ... Water is wasted ... The price is wrong
2a) Here's How 139 Countries Can Convert to 100% Renewable Energy by 2050
... successful implementation of the plan would mean that solar would provide 58% of the world's energy, 37% from wind and the remainder would come from a mix of hydroelectric, geothermal, tidal and wave energy. ... this transition would be expensive ... roughly $125 trillion. ... roughly equal to the direct price of the fossil fuel infrastructure.
2b) 100% renewable by 2050: the technology already exists to make it happen
People need to be clear that renewables are the way forward. We may differ with Jacobson and his team over the best type of energy storage, but there is a lot of value in this sort of ambitious roadmap. It emphasises the scale of the challenge, and, if done right, it should bolster general opinion and inspire action. The Paris Agreement was a good example of target-setting but details matter.
3a) Exxon researched climate science. Understood it. And misled the public
In its public-facing advertorials, Exxon stressed doubt; in its internal documents and peer-reviewed research, it did not.
3b) What Exxon Mobil Didn’t Say About Climate Change - The New York Times
Exxon Mobil misled the public about the state of climate science and its implications. Available documents show a systematic, quantifiable discrepancy between what Exxon Mobil’s scientists and executives discussed about climate change in private and in academic circles, and what it presented to the general public.
4) To solve climate change, solve income inequality
Holmberg, an economist, believes inequality is a byproduct of Wall Street’s preoccupation with short-term growth. She said that “public companies that only prioritize next-quarter share prices — and pump up those share prices through stock buybacks — are an enormous driver of inequality.” She added that “corporate short-termism, by its very definition, is bad for the environment because the same shareholder incentives that skew companies away from investing in workers, capital, and innovation discourage them from investing in, for example, green retrofitting of existing buildings, sustainable production practices, and even compliance with environmental regulations.”
5) California has a climate problem, and its name is cars
California’s experience shows that decarbonizing the electricity sector is both possible and profitable, but to reach its ambitious carbon targets, the state will now have to decarbonize transportation — which brings a whole new and daunting set of difficulties. ... transportation is the single biggest source of the state’s carbon emissions, more than twice as big as the electricity sector: ... The state can no longer pretend that its housing crisis is one thing and its climate crisis another. Smart urbanism is a key part of a smart climate strategy.
