The study, "Integrated Assessment of Black Carbon and Tropospheric Ozone," by the U.N. Environment Programme, shows the impact that the two short-lived pollutants have on the environment, compared with carbon dioxide, which can stay in the atmosphere for decades.

Global warming rate could be halved by controlling 2 pollutants, U.N. study says 2011

At first I did a little research on Tropospheric Scatter, which involves bouncing radio waves off the lower atmosphere.

Not to mention Russian atomic/nuclear reactors re-entering the earths' atmosphere and possible irradiation Stratospheric or Tropospheric levels in Earths' atmosphere seems like much more work must be completed before even contemplating the veracity of these claims.

Tropospheric scatter - a form of microwave radio transmission in which the troposphere is used to scatter and reflect a fraction of the incident radio waves back to earth; powerful, highly directional antennas are used to transmit and receive the microwave signals; reliable over-the-horizon communications are realized for distances up to 600 miles in a single hop; additional hops can extend the range of this system for very long distances.
