Swiss Researchers Try to Make it Rain With Lasers

formaggio writes "Last year a team of researchers at Switzerland's University of Geneva had come up with an interesting way of making it rain– by shooting lasers high up into the sky. At the time it seemed like science fiction, but now they are one step closer after the team successfully finished tests around Lake Geneva. From the article: 'Records from 133 hours of firings revealed that intense pulses of laser light created nitric acid particles in the air that behaved like atmospheric glue, binding water molecules together into droplets and preventing them from re-evaporating. Within seconds, these grew into stable drops a few thousandths of a millimeter in diameter: too small to fall as rain, but large enough to encourage the scientists to press on with the work.'"

Besides, a cloud is already a bunch of droplets that have formed around condensation nuclei. These droplets then sink to an altitude below the dew point and then simply evaporate again (forming the base of the cloud). So how can cloud seeding overcome the altitude of the dew point?

      Kirby, J. et al. 2011. Role of sulphuric acid, ammonia and galactic cosmic rays in atmospheric aerosol nucleation, Nature 476, 429–433 (25 August 2011)

      It is strange that the "climate-change/global-warming religion" didn't prevent its publication. I also don't see much evidence that "CERN is not offering much press on this", given that the paper is in Nature, a rather well-known scientific journal, and CERN itself has a press release about it, where this statement is made:

      "The CLOUD results show that a few kilometres up in the atmosphere sulphuric acid and water vapour can rapidly form clusters, and that cosmic rays enhance the formation rate by up to ten-fold or more. However, in the lowest layer of the atmosphere, within about a kilometre of Earth's surface, the CLOUD results show that additional vapours such as ammonia are required. Crucially, however, the CLOUD results show that sulphuric acid, water and ammonia alone – even with the enhancement of cosmic rays - are not sufficient to explain atmospheric observations of aerosol formation. Additional vapours must therefore be involved, and finding out their identity will be the next step for CLOUD."

      There are more details on that page, such as this PDF, which states:

      "This result leaves open the possibility that cosmic rays could also influence climate. However, it is premature to conclude that cosmic rays have a significant influence on climate until the additional nucleating vapours have been identified, their ion enhancement measured, and the ultimate effects on clouds have been confirmed."

      Emphasis added.

      If he doesn't like the account from Discover Magazine/Phil Plait, there's also this one from PhysOrg.com. Maybe with these sources he can manage to find one that isn't as liberally biased as he seems to think most of reality is.

      Um... cosmic rays do not come from the Sun, in fact when the Sun is at the top of its 11 year cycle cosmic rays are suppressed by the Sun's magnetosphere and vice versa.

      No one is suppressing the story about this research unless you think pointing out that doesn't mean as much as WattsUpWithThat and others want it to mean with regards to global warming is suppressing it.

Several hundred silver-iodide generators were spread around the county, and, when conditions were right, the call went out to turn them on. This increased rain in the agricultural valley, while reducing it in the barren inland hills. The end result was about 10% more rain.
