Sugarcane bioethanol: Environmental implications
Researchers have long promoted biofuels produced from crop biomass as an environmentally sustainable source of renewable energy. A recent study questions whether the potential climate benefit of sugarcane ethanol is diminished when emissions from la…
Berkeley scientists highlight challenges of meeting state energy goals by 2050
California is showing the way for the rest of the nation in terms of reducing greenhouse gas emissions, having set an ambitious goal to reduce these emissions to 80 percent below 1990 levels by the year 2050. Given that energy demand is projected …
Measuring methane
MADISON, WI, MARCH 1, 2011 — Methane is an extremely potent greenhouse gas. Wetlands, gas hydrates, permafrost, termites, oceans, freshwater bodies, non-wetland soils, are all natural sources of atmospheric methane; however, the majority of methan…

If greenhouse gas emissions stopped now, Earth still would likely get warmer
While governments debate about potential policies that might curb the emission of greenhouse gases, new University of Washington research shows that the world is already committed to a warmer climate because of emissions that have occurred up to no…
Rising seas will affect major US coastal cities by 2100
Rising sea levels could threaten an average of 9 percent of the land within 180 U.S. coastal cities by 2100, according to new research led by University of Arizona scientists.
The Gulf and southern Atlantic coasts will be particularly hard hi…
Ocean fertilization summary for policymakers published
Failure to tackle rising greenhouse gas emissions effectively has led to intensifying debate on geoengineering – deliberate large-scale schemes to slow the rate at which Earth is heating up. The public debate often mixes opinion with fact so scie…
