EPA Climate Change Adaptation Plan sees likely increase in tropospheric ozone, with more difficulty in attaining NAAQS in many areas

Green Car Congress

Among the many climate-related vulnerabilities that can impact its mission, the US Environmental Protection Agency (EPA) cites a likely increase in tropospheric ozone pollution as potentially making it more difficult to attain National Ambient Air Quality Standards ( NAAQS ) in many areas with existing ozone problems.

UN report projects that increasing use of HFCs likely to have a significant climate impact by 2050; equivalent to current total annual emissions from transport

Green Car Congress

The decrease in CO 2 equivalent emissions of ODSs (ozone-depleting substances: CFCs, halons, HCFCs, and others) may be offset by the projected increase in their non-ozone depleting substitutes (HFCs) (lines designated as HFC scenarios). The contribution of HFCs to climate forcing is currently less than 1% of all greenhouse gases.

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

Green Car Congress

Current emissions of anthropogenic greenhouse gases (GHGs) have already committed the planet to an increase in average surface temperature by the end of the century that may be above the critical threshold for tipping elements of the climate system into abrupt change with potentially irreversible and unmanageable consequences, the authors write.

California ARB and NOAA Collaborating in $20M Research on Interaction of Air Pollution and Climate Change; One Atmosphere Approach

Green Car Congress

Schematic diagram of the trade-offs between the implications for regional air quality and global climate change of new policies for management of the atmosphere. The project builds upon the idea that air quality and climate change issues are linked through “one atmosphere”, an approach that demands coordination and multi-tiered approaches.

Report argues advanced HD natural gas vehicles foundational for California to hit air and climate goals; near zero-emission potential

Green Car Congress

Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. California’s Climate Protection Strategies do not help meet NAAQS Standards. Click to enlarge.

NSF issues solicitation for decadal and regional climate prediction using Earth Systems Models

Green Car Congress

The US National Science Foundation has issued a solicitation for Decadal and Regional Climate Prediction using Earth System Models (EaSM). NSF said that is chose a time span of several decades because within this timeframe modeled climate change responses appear to be insensitive to CO 2 forcing scenarios. —NSF EaSM solicitation.
