A few things that caught my eye this past week.
On the climate sensitivity and historical warming evolurion in recent coupled model ensembles [link]
Greenland’s largest glacier (Jakobshavn) has rapidly thickened since 2016. Thickening has been so profound the ice elevations are nearly back to 2010-2011 levels. The nearby ocean has cooled ~1.5°C – a return to 1980s temperatures. https://the-cryosphere.net/14/211/2020/tc-14-211-2020.pdf

Could climate change and deforestation spark Amazon ‘dieback’? [link]

A new (2020) 5680-year tree-ring temperature reconstruction for southern South America – the longest ever for the Southern Hemisphere – shows the warmest era of the last millennium was the 1700s-1800s. The region has had no net warming from 1979-2009. https://sciencedirect.com/science/article/pii/S0277379119306924
Sea level pressure has, historically, worked as a better predictor of continental US #hurricane damage than maximum sustained wind: https://journals.ametsoc.org/doi/abs/10.1175/BAMS-D-19-0062.1

We need to get serious about ‘critical materials’ [link]

Cutting ozone-generating gas emissions from the largest human-made sources, including road transportation and energy production, could improve conditions for plants, allowing them to grow faster and capture more carbon, [link]
A climate catastrophe in Scotland 300 years ago contributed to widespread famine, an (unsuccessful) attempt to colonize Panama, and unification with England. [link]
