Scientists pour cold water on climate cooling claims - Lloydslist.com

CLIMATE change scientists working on European Union-funded research have poured cold water on the theory that shipping emissions produce a net cooling effect on the earth’s climate.

Shipping industry groups including the Greek Shipping Co-Operation Committee had hoped to pursuade regulators that shipping’s impact on the climate was at least benign and potentially beneficial.

But David Lee of Manchester Metropolitan University told a meeting at the International Maritime Organization that while shipping’s sulphur emissions created localised cooling, the effect was not great enough to offset the warming effects elsewhere.
