Amending the Montreal Protocol

UN Kigali Amendment Boosts Global Environmental, Climate Change Prospects

National representatives to the UN Montreal Protocol took action to phase out production and use of hydrofluorocarbons (HFCs) at a meeting in Kigali, Rwanda this past week. In addition to further reducing destruction of atmospheric ozone, the Kigali Agreement is expected to reduce projected mean global temperature rise 0.5 degrees Celsius over the course of the century.

The Space Solar Power Initiative (SSPI) is a team of scientists from Caltech that includes researchers from NASA’s jet propulsion laboratory. These scientists propose building the largest-ever space structure…
