Hydroelectric Dam Reservoirs Eat Up More CO2 Than They Produce, Unlike Previously Thought

Ten years ago, a report based on measurements taken at a hydroelectric plant in Brasil said that the gas (CO2 and methane) emissions of hydroelectric power (HEP) reservoirs account for 1 to 28% of the total greenhouse gas emissions caused by man. The report said that the CO2 and the methane came from the rotting organisms contained in the HEP reservoirs.

NYU Professor Points Out Why Alternative Energy Production Doesn't Grow As Expected

There are scientists who are optimistic about the chances we have to heal the planet and reduce its warming, scientists who are definitely rejecting anything related to global warming, saying it doesn’t exist, and scientists who are butt-kickers and telling the world what works and what doesn’t. Martin Hoffert, from the University of New York, is one of the third kind, in my opinion.

Besides Warming the Planet, High CO2 Levels Could Also Affect Our Crops' Nutritional Qualities

We have been talking about global warming lately, and implicitly of carbon dioxide as being one of the gases associated with it. We have also been talking about carbon dioxide’s indirect effect on warming through the modification it brings to trees, but never has the carbon dioxide been associated with crop plants’ nutritional values before, which affect us, humans, directly.
