New report by the California Air Resources Board finds that ride-hailing services like Uber/Lyft emit 50% more CO2 per passenger mile than regular cars — even though they use more efficient vehicles — because they travel passenger-less much of the time: https://ww2.arb.ca.gov/sites/default/files/2019-12/SB%201014%20-%20Base%20year%20Emissions%20Inventory_December_2019.pdf

Large regions of the ocean are cooling, but the warming regions slightly offset it. https://tandfonline.com/doi/full/10.1080/16000870.2018.1471911

In contrast to general belief, more leads (open water from cracks in Arctic sea ice) during Arctic winter are resulting in less clouds not more. Interesting. https://nature.com/articles/s41467-019-14074-5 https://phys.org/news/2020-01-arctic-sea-ice-clouds.html

A Brown U. Professor took on big pharma.  His university pulled him from the classroom [link]
