Seven of the ten monitored weather stations experienced average Mean temperatures above the Paris Accord’s limit this week. Washington DC’s relative cold sent me looking online for confirmation and I found some comments about cool temperatures and rainstorms. The forecast is for a cooler than usual summer there. The heat in India has made an impression on Mumbai. It’s running average is no longer below Pre-Industrial levels. Buenos Aires continues to warm, and summer seems to have arrived in Rome, thought Europe’s Eternal City continues to be cooler this year than the Ten Year Average (2008. To 2017/18). The north of England, represented by Durham Tees, has slipped back into chilliness.

This week’s twins are Shanghai and Sydney.

The Arctic Basin is a long way from any of my Ten Weather Stations but it seems reasonable to expect it will give an early warning of the Grand Solar Minimum’s arrival.
