Arizona State Students Develop a Solar-Powered Air Filtration System

Cars That Think

A drought in Mongolia has led to food shortages, prompting the nomads to migrate to the Ger district in the capital of Ulaanbaatar, one of the world’s most polluted cities. During the past few years, children living in the polluted district have lung functions that are 40 percent lower than those living in rural areas, according to UNICEF.

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

Noting the references in scientific and policy literature to the need for fast-action mitigation to help avoid DAI and abrupt climate changes, the authors define “fast-action” to include regulatory measures that can begin within 2–3 years, be substantially implemented in 5–10 years, and produce a climate response within decades.

Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Pollution from ships creates lines of clouds that can stretch hundreds of miles. The difference helps explain how much industrial pollution influences clouds.

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

This assessment provides an evaluation of black-carbon climate forcing that is comprehensive in its inclusion of all known and relevant processes and that is quantitative in providing best estimates and uncertainties of the main forcing terms: direct solar absorption, influence on liquid, mixed-phase, and ice clouds, and deposition on snow and ice.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

For example, a covered source (an entity in the power generation, chemicals, steel, and cement industries) can make reductions beyond its compliance obligations and then sell these reductions as credits to other covered sources. Nitrous oxide (N 2 O) emissions from agricultural operations or specific industrial processes (GWP = 298).
