I propose to change this list
  • The techniques use natural and reusable resources i.e. sea water and wind
  • Cloud albedo levels can be monitored via satellite and the sea spraying mechanisms could be adjusted to fit the data.
  • Albedo enhancement is considerably cheaper than many other geoengineering techniques.
  • It utilizes already existing technologies to send sea water droplets into low level oceanic clouds.
  • The location of the albedo enhancement of clouds can be controlled and localized. This could prevent ecological problems.
  • Cooling can happen in only the places in which it is required.
to this
Marine cloud brightening possesses the general advantages of solar radiation management. For example, it presently appears to be inexpensive relative to climate change damages and greenhouse gas emissions abatement, fast acting, and reversible in its direct climatic effects. Compared with other proposed solar radiation management methods, such as stratospheric aerosols injection, marine cloud brightening may be able to be partially localized in its intended effects.[1] This could, for example, be used to stabilize the West Antarctic Ice Sheet. Furthermore, marine cloud brightening, as it is currently envisioned, would use sea water and wind, which are both natural and plentiful.
The first bullet is captured at the end of my paragraph. The second bullet was general to all solar radiation management methods. The third bullet was highly speculative as no thorough cost assessments of cloud brightening have been undertaken. The fourth bullet was questionable, as the necessary technologies do not all currently exist. The fifth bullet was overstated, and a more accurate version is in my paragraph. The sixth bullet repeated the fifth bullet. --Jesse L Reynolds (talk) 13:09, 17 November 2015 (UTC)

Split off cirrus cloud thinning, and rename[edit]

I propose to split cirrus cloud thinning off into a separate page. That does not modify cloud reflectivity but instead allows longwave radiation to escape.

I also propose to rename this page "marine cloud brightening." That is by far the standard term used in both popular and academic media.

Requested move 06 October 2016[edit]

The following is a closed discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review. No further edits should be made to this section.

The result of the move request was: requester (Jesse L Reynolds) acted on this, okay with IAR closing (non-admin closure) — Andy W. (talk ·ctb) 18:19, 10 October 2016 (UTC)

Cloud reflectivity modificationMarine cloud brightening – The new name is used much more often but I can't seem to overwrite the redirect. – Jesse L Reynolds (talk) 14:46, 6 October 2016 (UTC)

This is a contested technical request (permalink). — Andy W. (talk ·ctb) 17:37, 6 October 2016 (UTC)
