The most impressive facts of this week are definitely the Geo-engineering, Dr. Wolf has a ~Tera Watts laser which can modify the water molecules of water in the atmosphere and this triggers cloud formation. Also, thunder storms could be redirected using this powerful laser technique.

Together with this talk we had a very basic physics lecture (not so basic to me) about the principles of radiation, then how to measure scattered radiation from particles in the clouds and further we will talk about LIDAR measurements and cloud vertical structure.
Also heath issues from pollution and Indoor air pollution sources and policy.
