Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? Research takes a long time.

Selin and colleagues compared the health benefits to the economic costs of three climate policies: a clean-energy standard, a transportation policy, and a cap-and-trade program. In 2011, 231 counties in the US exceeded the EPA’s regulatory standards for ozone, the main component of smog. Climate Change Emissions Health Policy'

—Co-author Professor Thomas Münzel, of the Department of Cardiology of the University Medical Centre Mainz. Since most of the particulate matter and other air pollutants in Europe come from the burning of fossil fuels, we need to switch to other sources for generating energy urgently. They focused particularly on PM 2.5

Researchers at Tohoku University in Japan have identified a way to reduce harmful NO emissions produced by ammonia fuel during combustion. Nitric oxide is known to be harmful to human health, contributes to ozone depletion, and when it reacts with other compounds, contributes to acid rain and atmospheric warming.

A study by researchers at Lund University in Sweden found that Swedish biofuels produce between 65 and 148% less greenhouse gas emissions than gasoline and diesel, even when direct and indirect land use changes are taken into account.

In general, biofuels made from organic waste are environmentally more benign than those from energy crops. Using biomass primarily for material purposes, reusing and recycling it, and then recovering its energy content can gain multiple dividends. Lifecycle analysis.

As we confront the enormous challenge of climate change, we should take inspiration from even the most unlikely sources. Take, for example, the tens of thousands of fossil-fueled ships that chug across the ocean, spewing plumes of pollutants that contribute to acid rain, ozone depletion, respiratory ailments, and global warming.

It’s often called geoengineering in the popular press, but the preferred term is climate intervention. Transcript. It’s very low concentration.
