The article discusses efforts by U.S., Saudi Arabia, and Brazil representatives to block a study of geoengineering methods of climate change prevention at a United Nations environmental summit in Nairobi, Kenya.

An editorial is presented on climate geoengineering approaches to limit the global temperature rise. Topics discussed include two types of geoengineering to reduce greenhouse gas emissions including carbon dioxide removal from the atmosphere, and solar radiation management to cool the Earth; need for a strategic approach to climate geoengineering policies to prevent other serious risks of geoengineering; and frameworks on the use of geoengineering created by Convention on Biological Diversity.

The article discusses the U.S. government body Global Change Research Program's recommendations that the U.S. should fund research on geoengineering to prevent climate change, including through reducing carbon in the atmosphere and improving Earth's albedo [ABSTRACT FROM PUBLISHER]

In this article the authors discuss aspects of a report by researcher Blackstock and colleagues regarding the exploration of the feasibility, potential impact, and dangers, associated with shortwave climate engineering. The authors note observations that indicate the reduction of shortwave radiation, in an effort to reduce climate warming, may risk precipitation changes and discuss the controversy surrounding the benefits and risks of geoengineering solutions.

The article discusses why the U.S. National Research Council (NRC) has announced that the U.S. government should fund research in the field of climate engineering. Topics include the concept of albedo modification through such methods as making clouds more reflective, how the Department of Energy has pulled funding initiatives for similar research in the past for fear of bad publicity, and how climate change skeptics have impacted research.
