I've never taken much of an interest in the chemtrail thing, but it does seem funny that governments are proposing to do more or less the same thing they denied doing! I can't see this being the answer though. Maybe I'm wrong, but it wouldn't be the first time environmental measures have proven destructive. Some of the most invasive pests have been brought in to control a less invasive ones e.g. cane toads in Australia. The road to Hell is paved with good intentions.
