Harvard Climate Scientist David Keith makes the case that global warming and CO2 pollution have become so severe that dramatic measures have to be researched immediately and applied by 2020. He is suggesting spraying particles from airplanes into the stratosphere to create a haze that will reduce solar radiation.
He names possible substances, including aluminum. However, his material of choice is sulfuric acid because it mimics volcanic explosions. He admits that such global intervention will damage the life protecting ozone layer, cause droughts and floods and will do nothing to resolve the expanding damage to the planet by still rising CO2 emissions.
He says that we need to artificially cool the earth because we are too slow to cut back on CO2 pollution. And that once begun, the spraying of aerosols cannot be stopped for the next 50 years because that in itself would be a dramatic shock to the world.
Professor Keith denies that real live experimentation of spraying from airplanes is occurring – in spite of the observations of so-called chemtrails all over the world. He does however admit that spraying from airplanes is easy and inexpensive – all you need is an airfield and a couple of planes – and that such activity would be very difficult to detect.
This and more is written up in his book: A Case for Climate Engineering, published in October 2013 at Massachusetts Institute of Technology. The prestigious Boston Review gave the book a release event that was videotaped. And the audio for this radio program comes from their web site.
