Projections and downscaling of 21st century temperatures, precipitation, radiative fluxes and winds for the Southwestern US, with focus on Lake Tahoe

“…1); the A2 scenario is a scenario that is based on assumptions of a very heterogeneous world economy with high population growth, moderate overall economic growth, and resulting emissions that accelerate throughout the 21st Century. Notably, until recently, the A2 scenario was viewed as a reasonable "worst case" scenario, but recent evaluations have shown that, in the past decade, emissions have actually exceeded the A2 trajectory (Raupauch et al 2007). Consequently, A2 is now viewed as more of a middle-of-the-road scenario (compared, e.g., to A1Fi in Fig.…”

Effective policies for renewable energy—the example of China's wind power—lessons for China's photovoltaic power

“…1), but the large population and high speed of economic development have been primary drivers of the recent acceleration in global carbon emissions [12]. China's economic growth is projected to continue at higher than 7% per year; at this rate, GDP would quadruple in 20 years [13].…”

Climate response to aerosol injection at different stratospheric locations

“…Moreover, the CO 2 emissions increase (Raupach et al, 2007) is exceeding even the most pessimistic of the IPCC projections (IPCC, 2001). Therefore, humankind will be forced to apply geoengineering to counter the unwanted consequences of global warming.…”
