OK, this is totally unscientific. On July 5th we launched the new network.

SINGAPORE (Reuters) - A huge hole that appeared in the Earth's protective ozone layer above the Arctic in 2011 was the largest recorded in the Northern Hemisphere, triggering worries the event could occur again and be even worse, scientists said in a report on Monday. The ozone layer high in the stratosphere acts like a giant shield against the Sun's ultraviolet (UV) radiation, which can cause skin cancers and cataracts

Next month, researchers in the U.K. will start to pump water nearly a kilometer up into the atmosphere, by way of a suspended hose.

First, though, the British government is going to put a normal sized balloon in the sky to see if spraying water to refract the sun's light can really prevent climate change. Maybe we'll need a Plan B

Despite significant pyrotechnics and air travel disruption last year, the Icelandic volcano Eyjafjallajokull simply didn't put that many aerosols into the stratosphere. In contrast, the eruption of Mount Pinatubo in 1991, put 10 cubic kilometers of ash, gas and other materials into the sky, and cooled the planet for a year. Now, research suggests that for the past decade, such stratospheric aerosols--injected into the atmosphere by either recent volcanic eruptions or human activities such as coal burning--are slowing down global warming.
