Ratio Between Black Carbon and Sulphates in Atmosphere Crucial to Global Warming

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.

New Study Estimates Impact of Soot on Global Warming and Timeframe of Actions to Be Taken

New Study Estimates Impact of Soot on Global Warming and Timeframe of Actions to Be Taken

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.

DNA-Like Metal Organic Frameworks to Store Carbon Dioxide Efficiently

DNA-Like Metal Organic Frameworks to Store Carbon Dioxide Efficiently

UCLA scientists, led by professor Omar M. Yaghi have created three-dimensional, synthetic DNA-like crystals which are capable of storing carbon dioxide: We have taken organic and inorganic units and combined them into a synthetic crystal which codes information in a DNA-like manner.

Throwing Chemicals Into The Air - Solution to Global Warming?

Certain bright minds say we should throw trillions of mirrors into space to slow global warming. It doesn’t seem like a bad idea at a first glance, but other enlightened thoughts say we should release chemicals into the air to do just that.

1. First of all, remove the aggressive tendency from your driving habits. I admit I myself like to be aggressive sometimes, it gives me chills, diesel cars have a lot of torque at low rpm, but from what I experienced that go fast-full stop-go-fast attitude costs me about 2 liters more per hundred kilometers. Sometimes [...]

New Carbon Collecting Car – Really That Green?

Georgia Institute of Technology has created a concept of a car in a pretty new polluting fashion: it uses petrol as a fuel, but it separates hydrogen and carbon dioxide. The hydrogen is used in a fuel cell, and the CO2 is collected and recycled. Now, I know my website’s name is “greenoptimistic.com”, but this [...]
