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

Among the non-CO 2 pollutants are hydrofluorocarbons (HFCs), methane, tropospheric ozone, and black carbon soot. The next round of UN climate negotiations begins in Cancun today. ” The authors go on to say that reducing the non-CO 2 pollutants can delay additional climate warming by several decades.

CICERO-led study finds global warming effect of leaked hydrogen almost 12x stronger than CO2

Green Car Congress

A study led by Norwegian climate center CICERO has found that the global warming effect of leaked hydrogen is almost 12 times stronger than that of CO 2. Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. The climate effects of hydrogen have been an under-researched topic.

However, climate models to date have mischaracterized the effects of soot in the atmosphere, according to Jacobson, director of Stanford’s Atmosphere/Energy Program. 1990; Anisimov, 2007] and chemical production of ozone in already-polluted locations [Jacobson, 2008b].

(The figure includes the direct effects and those indirect effects due to the production of tropospheric ozone and stratospheric water vapor.) In 2011, CH4 emissions from coal mining were 63.2 Climate Change Emissions Natural Gas' From 1990 to 2011, CH4 emissions from landfills decreased by 44.7 Tg CO 2 Eq., Tg CO 2 eq.

MIT study finds including non-CO2 emissions from synthetic aviation fuel in lifecycle analysis of climate impact can lead to decrease in relative environmental merit; need for a holistic analysis framework

Aviation climate change impacts pathway. An an example, they point out that an SPK fuel option with zero life cycle GHG emissions would offer a 100% reduction in GHG emissions but only a 48% reduction in actual climate impact using a 100-year time window and the nominal climate modeling assumptions in the paper.
