Emissions estimations should embed a precautionary principle

To align their portfolios with the Paris Agreement, investors need to know the emissions of companies they invest in. Estimating these should start from a precautionary principle that disincentivizes free-riding and protects the planet.

New insights into future tropical climate change

Nature Climate Change, Published online: 29 July 2021; doi:10.1038/s41558-021-01107-5

The difference between tropical east and west Pacific sea-surface temperatures affects local and global climate, and most climate models suggest a weaker future gradient despite a recent observed increase. Research now suggests the recent trends are due to a transient delay in east Pacific warming driven by cold water upwelling and aerosols.

Eastern equatorial Pacific warming delayed by aerosols and thermostat response to CO2 increase

Nature Climate Change, Published online: 29 July 2021; doi:10.1038/s41558-021-01101-x

The tropical Pacific east–west temperature gradient intensified recently, but climate models do not reproduce this, and they also predict future weakening. This discrepancy is attributed to a competition between long-term weakening and transient strengthening from aerosols and ocean equatorial upwelling.

Reports highlight how to repair the Appalachian economy without relying on fracking
