Although fossil - fuel combustion has generated most of the buildup of climate - altering carbon dioxide (CO2) in the atmosphere, effective solutions will require more than just designing cleaner energy sources.

«When it comes to life cycle greenhouse gas emissions, wind and solar energy provide a much better greenhouse gas balance than fossil - based low carbon technologies, because they do not require additional energy for the production and transport of fuels, and the technologies themselves can be produced to a large extend with decarbonized electricity,» states Edgar Hertwich, an industrial ecologist from Yale University who co-authored the study.

Fake paper fools global warming naysayers The man - made - global - warming - is - a-hoax crowd latched onto a study this week in the Journal of Geoclimatic Studies by researchers at the University of Arizona's Department of Climatology, who reported that soil bacteria around the Atlantic and Pacific oceans belch more than 300 times the carbon dioxide released by all fossil fuel emission, strongly implying that humans are not to blame for climate change.

Hydrogen can also be split from water in high - temperature nuclear reactors or generated from fossil fuels such as coal or natural gas, with the resulting carbon dioxide captured and sequestered rather than released into the atmosphere.
