Ratio Between Black Carbon and Sulphates in Atmosphere Crucial to Global Warming
Black carbons are emitted from diesel exhausts and burned biomass and are considered an environmental and health hazard all over the world. Besides the fact that they favor global dimming, black carbons also attract heat.
Genetically Modified Enzyme Leads to Better Carbon Sequestration at Coal Powered Plants
Capturing the carbon dioxide that a coal-powered plant produces and sequestering it is not an easy task, and until now it rose the costs of the electricity produced by 80 percent. Due to researchers at Codexis, a Redwood, CA, company, genetically modified enzymes can make carbon dioxide capture much cheaper, increasing the cost of electricity by less than a third.
New Study Estimates Impact of Soot on Global Warming and Timeframe of Actions to...
Soot is considered one of the most important threats to the environment, along with carbon dioxide. Princeton University researchers have described the contribution of soot ("carbonaceous aerosols") to phenomena of global warming and global dimming. Soot is born by incomplete combustion and comes mostly from diesel engines and coal burning.
Good News: Global Greenhouse Gas Emissions Dropped by 1.1 Percent in 2009
Among the dozen of bad news that keep filling our mailboxes daily, we once in a while read something worth smiling at: the global greenhouse emissions generated by energy use dropped for the first time since 1998, by 1.1 percent. Through this, the economic crisis has its good actions, because it reduced the industrial production and fossil fuel consumption worldwide.
New Metal-Organic Frameworks In Action for Capturing Carbon Dioxide
Climate change is one of the most controversial subjects of the century, because it is changing our planet in an non-imaginable way. Scientists have developed different ways (more or less efficient) to capture the CO2 excess resulted from human activity.
UK Scientists Predict Aircraft as Significant Source of CO2 for Next 10 Years
A 10-year prediction made by Bethan Owen and her colleagues from the UK's CATE (Center for Air Traffic and the Environment) says that aircraft emissions will become the a significant source of carbon dioxide and other greenhouse gases, and will double or triple by 2050.
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.
Too Much CO2 Causes Plants Not to Cool The Earth As They Should, Says...
Trees and green plants, generally, are used by the planet as a way to keep itself cool. A regular tree can evaporate as much as ten gallons of water a day, acting as a natural air conditioner for its surroundings. So trees are important for their CO2-sequestration capabilities and keeping things cool(er).
Link Between Whale Droppings and Carbon Sequestration Discovered
The Australian Antarctic Division performed a research in this area, and found out that the whale poo is very rich in iron - about some 10 million times richer than sea water, as Steve Nicol, one of the scientists, said: "The plants love it and it actually becomes a way of taking carbon out of the atmosphere."
Micro-Bubbles Injected Into Oceans Reduce Global Warming, Physicist Says
Russell Seitz, a physicist at the Harvard University, has thought of an ingenious way to fight global warming by cooling the planet by parts. The ingenious way Seitz wants to do this is by pumping vast swarms of tiny bubbles into the sea to increase its reflectivity.
