What is Geoengineering?

Posted in ideas, your take on... by aldorf on June 13, 2010

It’s human manipulation of the climate. Scientist believe it could be a way of slowing down global warming while efforts to reduce greenhouse gas emissions continue. Cloud whitening is one example. Geo engineers are proposing to use off-shore vessels to pump sea spray into the atmosphere. The salt particles in the spray would in theory help to form brighter clouds that reflect more sunlight back into space, thus having a cooling effect on climate. Unfortunately scientists from the University of Leeds and the Finnish Meteorological Institute found that generate brighter clouds may actually hinder natural cloud formation in some areas.

The Known Universe

Posted in Animation, film by aldorf on December 29, 2009

The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world’s most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History. The new film, created by the Museum, is part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010.
