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.

Low-lying and other vulnerable countries calling for fast action on non-CO2 global warming pollutants

Green Car Congress

Led by the tiny Pacific island of the Federated States of Micronesia, a growing group of low-lying islands and other vulnerable countries are calling for fast action on the approximately 50% of global warming that is caused by pollutants other than carbon dioxide (CO 2 ). The next round of UN climate negotiations begins in Cancun today.

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. By 2050, HFC emissions could equal up to 19% of global CO 2 emissions under business-as-usual scenarios. million people a year, global action to cut soot emissions would reap major benefits for both public health and climate.

ICCT study finds that transitioning to low-GWP MAC refrigerants in China could avoid up to US$150B in costs

Green Car Congress

The costs of transition are generally favorable compared to other available CO 2 reduction technologies for motor vehicles. MAC technology and equipment is generally of a commodity nature and is available through third-party suppliers to any vehicle manufacturer.

Study Highlights the Importance of Considering Climate Effects of Non-CO2 Emissions from Transport in Mitigation Strategies and Policies

Green Car Congress

Radiative forcing from the global and US ORT and PG sectors. The on-road transportation (ORT) and power generation (PG) sectors are major contributors to CO 2 emissions and a host of short-lived radiatively-active air pollutants, including tropospheric ozone and fine aerosol particles, that exert complex influences on global climate.

Volkswagen to use CO2 as refrigerant for future air conditioning systems

Green Car Congress

The Volkswagen Group announced that it is choosing CO 2 as the future low global warming potential (GWP) refrigerant for its mobile air conditioning (MAC) systems. With a GWP (Global Warming Potential) value of 1, R744 is 99.3% It has a high cooling capacity and is available worldwide at low cost in the required qualities.

Royal Society Report Concludes Geoengineering and its Consequences May be the Price for Failure to Act on Climate Change; Recommendations for Plan B

Green Car Congress

Geoengineering is defined as the deliberate large-scale intervention in the Earth’s climate system in order to moderate global warming. Enhanced weathering – this technique, which utilizes naturally occurring reactions of CO2 from the air with rocks and minerals, was identified as a prospective longer-term option.
