1. Florida property insurance is going up. Reinsurance is beginning to respond to the climate crisis. https://climatecrocks.com/2021/03/31/climate-juiced-storms-jack-up-florida-home-insurance-bills/

2. Weather changes attendant on climate change have reduced global agricultural productivity growth 21% since 1961.  https://phys.org/news/2021-04-climate-global-agricultural-productivity-1960s.html?utm_source=nwletter&utm_medium=email&utm_campaign=daily-nwletter
The review, including its title, seems to confuse productivity loss and diminution of productivity growth. It is 21% of the potential growth which we have lost. We are going to have to dance all the harder to keep the accelerating beat.  https://www.nature.com/articles/s41558-021-01000-1

3. Meltwater from Eurasian and North American ice sheets was behind much of a 60 foot rise in sea level 14,600 years ago. We have gotten much better at fingerprinting the source of past sea level rise. https://www.upi.com/Science_News/2021/04/01/britain-ice-sheet-melting-sea-level-rise/6451617281884/

4. Lithium-ion batteries are good at short-term energy storage, but to handle grid-size applications requiring days of storage we need new (and cheap) long duration energy storage systems. Several possibilities are under exploration. https://climatecrocks.com/2021/04/02/learn-this-acronym-ldes-long-duration-energy-storage/

5.  President Biden’s infrastructure proposal would address power and transportation issues. It is a promising beginning. https://phys.org/news/2021-04-biden-infrastructure-climate-crisis.html

6. A record 260 GW of new renewable energy was added globally in 2020, 80% of new capacity. https://renews.biz/67691/record-260gw-of-clean-power-added-in-2020/
