Federal Advisory Committee Draft Climate Assessment Report Released for Public Review

A 60-person Federal Advisory Committee (The "National Climate Assessment and Development Advisory Committee" or NCADAC) has overseen the development of this draft climate report. 

The NCADAC, whose members are available here (and in the report), was established under the Department of Commerce in December 2010 and is supported through the National Oceanic and Atmospheric Administration (NOAA). It is a federal advisory committee established as per the Federal Advisory Committee Act of 1972. The Committee serves to oversee the activities of the National Climate Assessment. Its members are diverse in background, expertise, geography and sector of employment. A formal record of the committee can be found at the NOAA NCADAC website

The NCADAC has engaged more than 240 authors in the creation of the report. The authors are acknowledged at the beginning of the chapters they co-authored. 

Following extensive review by the National Academies of Sciences and by the public, this report will be revised by the NCADAC and, after additional review, will then be submitted to the Federal Government for consideration in the Third National Climate Assessment (NCA) Report. For more information on the NCA process and background, previous assessments and other NCA information, please explore the NCA web-pages. The NCA is being conducted under the auspices of the Global Change Research Act of 1990 and is being organized and administered by the Global Change Research Program.

Green Roofs Programme Rotterdam

Rotterdam tries to promote the construction of green roofs in several ways. With a subsidy scheme, for example, which will provide a financial incentive to have a green roof constructed. Where possible, green roofs will be built on top of municipal property. Building green roofs on top of third-party property, such as housing associations and businesses, will also be stimulated.


This has resulted in the construction of green roofs on top of the Municipal Archives building, the Central Library, the head office of Unilever Nederland, the Maasstad Hospital, the Sophia Children's Hospital and the museum Villa Zebra. In total, Rotterdam now has over 110.000 m2 of green roof, which is expected to be 160,000 m2 by the end of 2014. 

Since July 2008, the municipality of Rotterdam has had a subsidy scheme for green roofs. This scheme falls under the responsibility of the Rotterdam climate adaptation programme Rotterdam Climate Proof. People who want to construct a green roof can ask the municipality of Rotterdam for a subsidy of up to € 30.00/m2: € 25.00 will be provided by the City of Rotterdam and € 5.00 by the water boards. Citizens who live west of De Schie - part of the catchment area of the Delfland Water Board - will receive € 25.00 per m2: Due to budget cuts, the water board has cancelled the subsidy for disconnecting rainwater pipes.
