How’s this for hypocrisy? Fossil fuels now cause both global warming and global cooling.
For years, it has been pounded into us that fossil fuel burning produces high levels of carbon dioxide, which, in turn, causes global warming.
But a little publicized study from NASA found that the Earth has cooled – cooled! – in areas of heavy industrialization where more trees have been lost and more fossil fuel burning takes place.
The study found that aerosols created by burning fossil fuels actually cool the local environment, at least temporarily.
A NASA spokesman said it was “well known” that aerosols such as those emitted in volcanic eruptions and power stations, act to cool Earth, at least temporarily, by reflecting solar radiation away from the planet.
He added: “In a similar fashion, land use changes such as deforestation in northern latitudes result in bare land that increases reflected sunlight.”
The study found existing models for climate change had been too simplistic and did not account for these factors.
