Eruptions & Emissions cause changes in ocean carbon sinks

A new model explains why the ocean’s capacity to take up carbon was reduced on a decadal scale, by accounting for reduced pCO2 emissions and ocean state changes due to the eruption of Mt. Pinatubo.

Unnatural climate solutions? Nature Climate Change volume 10, pages98–99(2020)

Rob Bellamy on why the hype around ‘natural’ climate solutions threatens us all. His new paper is with Shannon Osaka. Abstract: Framing solutions to climate change as natural strongly influences their acceptability, but what constitutes a ‘natural’ climate solution is selected, not self-evident. We suggest that the current, narrow formulation of natural climate solutions risks constraining what are thought of as desirable policy options. https://www.nature.com/articles/s41558-019-0661-z
