Atmospheric Carbon Dioxide Reduction by Sacramento's Urban Forest
Sacramento County s 6 million trees store 8 mllllon tons of C O (31 t;ha). and annually sequester 238.000 t ( 0 92 tbhai Ar-condltionlng (157 GWh) and space-heating (145 TJ) savings from the urban forest further reduce emisslons by 75 600 t of CO annually (0 29 t:ha). These avolded emisslons are only 32"0 of the amount sequestered. due to a clean. hydroelectric energy supply. Annual COrelease a...

متن کاملTropical forests and atmospheric carbon dioxide.
Tropical forests play a major role in determining the current atmospheric concentration of CO2, as both sources of CO2 following deforestation and sinks of CO2 probably resulting from CO2 stimulation of forest photosynthesis. Recently, researchers have tried to quantify this role. The results suggest that both the carbon sources and sinks in tropical forests are significantly greater than previ...
متن کاملElevated atmospheric carbon dioxide and ozone alter forest insect abundance and community composition
1. Human-induced climate changes threaten the health of forest ecosystems. In particular, carbon dioxide (CO2) and tropospheric ozone (O3) will likely have significant but opposing impacts on forests and their associated insect communities. Compared with other animal groups, insect communities are expected to be especially sensitive to changes in global climate. 2. This study examined the effec...
متن کاملEffects of fuel and forest conservation on future levels of atmospheric carbon dioxide.
We develop a numerical simulation of the global biogeochemical cycles of carbon that works over time scales extending from years to millions of years. The ocean is represented by warm and cold shallow water reservoirs, a thermocline reservoir, and deep Atlantic, Indian, and Pacific reservoirs. The atmosphere is characterized by a single carbon reservoir and the global biota by a single biomas...
