Leon Simons@LeonSimons8 Mar 9 On January 1st 2020 new shipping regulation came into effect (#IMO2020), decreasing the maximum amount of sulfur in shipping fuels from 3.5% to 0.5%.

Leon Simons@LeonSimons8 Mar 9 If this trend continues that could mean that the Northern Hemisphere mid latitudes (where many of us live) will warm much more rapidly. It could also impact global and regional weather systems, like the monsoons. More extreme weather is likely.

These are from a paper Leon presented to the aerosol society.

An other thread he started is also fascinating about how warming is affecting the oceans despite water taking 3000 times more energy than air to increase its temperature by a degree.
