Conflicting Measurements Reduce Uncertainty in Climate Science [link]
California’s new earthquake warnings deliver critical seconds of notice [link]
Why are land-use change emissions so complex? Forests have direct (eg, deforestation), indirect (eg, CO₂ fertilisation), & natural effects (eg, storms). Policy & science treat these differently! [link]

Lively debate on ‘Emergent Constraints on Climate Sensitivity’ in today’s issue of Nature. Ostensibly variability-based constraints actually reflect a forced signal: https://doi.org/10.1038/s41586-018-0640-y … . Author’s reply: https://doi.org/10.1038/s41586-018-0641-x …
“all the indicators point to real problems with insect and invertebrates in decline across the world.” [link] …
“Our findings confirm the importance of the deep Southern Ocean in ice-age CO2 change, and show that deep-ocean CO2 release can occur as a dynamic feedback to rapid climate change on centennial timescales.” [link] …
I can’t recommend enough the paper by Tapiador et al. (2019) — … … — Succinct review of outstanding issues and assumptions in current cloud microphysics parameterizations [link]
Current CaCO3 dissolution at the seafloor caused by anthropogenic CO2 [link] …
Models suggest injection of #sulfateaerosols into the stratosphere could have unintended consequences [link]
In some groundbreaking CESM-WACCM geoengineering simulations, stabilizing surface temp interestingly fails to accompany stability in either Earth’s energy imbalance or polar ocean temps. [link]
