Study Finds Ozone, Nitrogen Change the Way Rising CO2 Affects Earths Water

Green Car Congress

Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

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?

If they meet all the pledges they've made for emission reductions by 2030, global temperature rise will be at 2.4° Many people see such actions as "playing God," and worry about the unintended consequences of meddling with nature on a global scale. Humanity is already reducing global warming. by spewing pollution into the air.

Losses of tropical and temperate mountain glaciers affecting perhaps 20-25% of the human population in terms of drinking water, irrigation and hydro-power. Global emissions were growing by 1.1% The developing and least-developed economies, 80% of the world’s population, accounted for 73% of the global growth of emissions in 2004.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

Brazil, the largest and most populous country in South America, was importing 80% of its oil and 40% of its foreign exchange was used to pay for that imported oil. The growth in hydrous ethanol, which uses a blend of 94-95% ethanol to 5-6% water, rapidly increased during the 1980s, with consumption peaking in 1989.

ICCT finds growth in shipping in Arctic could increase pollutant emissions 150-600% by 2025 with current fuels

Green Car Congress

MARPOL Annex VI sets limits on NO x and SO x emissions from ship exhaust, and prohibits deliberate emissions of ozone-depleting substances. Annex VI defines two sets of emission and fuel quality requirements: global requirements; and. more stringent requirements applicable to ships in Emission Control Areas (ECA). Earlier post.).

WHO links 7 million premature deaths annually to air pollution; 12.5% of total global deaths

Green Car Congress

The World Health Organization now estimates that in 2012 around 7 million people died—one in eight (12.5%) of total global deaths—as a result of air pollution exposure. Estimates of people’s exposure to outdoor air pollution in different parts of the world were formulated through a new global data mapping.
