‘This tends to make the air a more effective blanket for the Earth and to raise its temperature’, he said.
The article finished with the prophetic line; ‘The effect may be considerable in a few centuries’.
The finding suggests people knew about global warming and the impacts of burning coal earlier than originally thought.
And its predictions appear to be coming true.
Today, according to the Intergovernmental Panel on Climate Change (IPCC), concentrations of carbon dioxide, methane and nitrous oxide in the atmosphere are at their highest for at least the last 800,000 years.
Fourteen of the sixteen warmest years on record have occurred since 2000, with 2015 confirmed as the warmest year globally on record.
‘Such a run of high temperatures is extremely unlikely to have occurred in the absence of human-caused climate change,’ it says….[ ]
