More than 60% of global warming since 2001 has been due to lower pollution, UK researchers say

 An analysis of CERES data from 2001 to 2019 suggests that the biggest factor in global warming since 2001 is a reduction in sulphur dioxide (SO2) pollution and not an increase in carbon dioxide (CO2) in the atmosphere.

Researchers from the University of Exeter have found that a reduction in atmospheric SO2 has caused clouds to become darker, resulting in less solar radiation being reflected into space, leading to global warming.

At the Exeter Climate Conference earlier this month, University of Exeter researchers Professor Peter Cox and Margaux Marchant presented their initial findings of their analysis of CERES data, the New Scientist reported last week.

Peter Cox is Professor of Climate System Dynamics in Mathematics and the Director of the Global Systems Institute at the University of Exeter. He is a lead author on the 4th, 5th and 6th Assessment Reports of the UN’s Intergovernmental Panel on Climate Change (“IPCC”) and a member of the UK Government’s Defra Scientific Advisory Council.

Since 2001, satellite instruments known as CERES have been measuring the amount of sunlight that is reflected into space compared to the amount that is absorbed by the Earth. These measurements indicate a decline in the planet’s albedo, the Earth’s ability to reflect solar radiation. As a result, the Earth is becoming darker, leading to additional warming...<<<Read More>>>...
