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. A global warming potential of 11.6 Sand et al.

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

Controlling soot from fossil fuels and solid biofuels may be a faster method of reducing Arctic ice loss and global warming than other options, including controlling CH 4 or CO 2 , although all controls are needed, according to a new study by Dr. Mark Z. Particle traps filter out soot particles from exhaust fumes. Mark Jacobson.

Harvard team finds that the phase of atmospheric secondary organic material affects chemical aging; may require revision of regional and global climate models

Green Car Congress

The findings, published in the Proceedings of the National Academy of Sciences , demonstrate that phase can be a key regulator of the reactivity of atmospheric SOM particles, and may call for a revision of regional and global climate models. In the atmosphere, the particles of ?-pinene In dry conditions, they solidify without crystallizing.

Climate Expert: Don't Call It Geoengineering

Cars That Think

Everyone solemnly agreed, again, to follow the science, which has shown in exhaustive detail that humanity will suffer from heat, fire, floods, and droughts if the world warms beyond 1.5° If they meet all the pledges they've made for emission reductions by 2030, global temperature rise will be at 2.4° C above pre-industrial levels.

ICCT finds growth in shipping in Arctic could increase pollutant emissions 150-600% by 2025 with current fuels

Green Car Congress

MARPOL Annex VI sets limits on NO x and SO x emissions from ship exhaust, and prohibits deliberate emissions of ozone-depleting substances. Annex VI defines two sets of emission and fuel quality requirements: global requirements; and. more stringent requirements applicable to ships in Emission Control Areas (ECA).

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

The growth in hydrous ethanol, which uses a blend of 94-95% ethanol to 5-6% water, rapidly increased during the 1980s, with consumption peaking in 1989. water content in it and Gasoline C, or E25, which is a mixture of 75% Gasoline A and 25% in volume of anhydrous ethanol (AEAC) with a maximum of 0.4% 40 CFR § 80.27 40 CFR § 80.27(d)

EPA says methane emissions from natural gas production have dropped 36% from 2007-2011

Green Car Congress

Reasons the agency sited for this trend include factors such as increased voluntary reductions, as well as the effects of the recent global economic slowdown. a global warming potential of 21. a global warming potential of 21. Methane is more than 20 times as effective as CO 2 at trapping heat in the atmosphere—i.e.,
