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

Green Car Congress

HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.

Study finds paved surfaces in Houston worsen air quality

Green Car Congress

New research by a team from the US, China and Japan focusing on the Houston, Texas area suggests that widespread urban development alters weather patterns in a way that can make it easier for pollutants to accumulate during warm summer weather instead of being blown out to sea. ““The very existence of the Houston area favors stagnation.”

Study projects net cooling of climate from ship emissions through 2050

Green Car Congress

A recent study by an international team calculated that shipping causes a net cooling of climate across all parametrizations of the indirect aerosol effect (IAE) and scenarios throughout the period 1900?2050. A recent study commissioned by the International Maritime Organization (IMO) estimated total emissions of 1046 Tg CO 2 yr ?1

NASA GISS Study Finds That Methane Has an Elevated Warming Effect Due to Interactions With Aerosols

Green Car Congress

As a result of their findings, published in the 30 October issue of the journal Science , the authors argue that assessments of multigas mitigation policies, as well as any separate efforts to mitigate warming from short-lived pollutants, should include gas-aerosol interactions. Similar reactions influence the creation of nitrate aerosols.
