Lord Rees of Ludlowthe president of the Royal SocietyBritain’s most prestigious scientific institute, said: Efficient lighting and daylighting ; more efficient electrical appliances and heating and cooling devices; improved cook stoves, improved insulation ; passive and active solar design for heating and cooling; alternative refrigeration fluids, recovery and recycle of fluorinated gases.

Second generation biofuels; higher efficiency aircraft; advanced electric and hybrid vehicles with more powerful and reliable batteries.

Rajendra Pachaurithe IPCC chair, admitted at the launch of this report that since the IPCC began work on it, scientists have recorded “much stronger trends in climate change”, like the unforeseen dramatic melting of polar ice in the summer of[] and added, “that means you better start with intervention much earlier”. The process is labor-intensive, diverting time and resources from participating scientists’ research programs.

The Guidelines for National Greenhouse Gas Investories provide the methodological basis for the estimation of national greenhouse gas emissions inventories. Retrieved 22 December The report notes many observed changes in the Earth’s climate including atmospheric composition, global average temperatures, ocean conditions, and other climate changes.
