The Rate of Global Warming During Next 25 Years Could Be Double What it Was in the Previous 50, a Re

James Hansen, a climate scientist who shook Washington when he told Congress 33 years ago that human emissions of greenhouse gases were cooking the planet, is now warning that he expects the rate of global warming to double in the next 20 years.
While still warning that it is carbon dioxide and methane that are driving global warming, Hansen said that, in this case, warming is being accelerated by the decline of other industrial pollutants that theyve cleaned from it.
Plunging sulfate aerosol emissions from industrial sources, particularly shipping, could lead global temperatures to surge well beyond the levels prescribed by the Paris Climate Agreement as soon as 2040 unless appropriate countermeasures are taken, Hansen wrote, together with Makiko Sato, in a monthly temperature analysis published in August by the Climate Science, Awareness and Solutions center at Columbia Universitys Earth Institute.
