Although APS plans to reduce its coal burn from the current 35 % to 17 % by 2029, by increasing its natural gas burn from 19 % to 35 %, it will actually increase its greenhouse gas emissions in the near term, since the global warming potential from methane, which is leaked at multiple points of the natural gas supply chain, is 86 times that of carbon over 20 years, according to the Intergovernmental Panel on Climate Change's 2013 report.

Enhance Cooperation on Hydroflurocarbons (HFCs): Building on the historic Sunnylands agreement between President Xi and President Obama regarding HFCs, the United States and China will enhance bilateral cooperation to begin phasing down the use of high global warming potential HFCs, including through technical cooperation on domestic measures to promote HFC alternatives and to transition government procurement toward climate - friendly refrigerants.

al., Enhanced CO2 uptake at a shallow Arctic Ocean seep field overwhelms the positive warming potential of emitted methane.

The Technology Warming Potential approach [of the new Alvarez et al paper] seems to be a step backward from simply calculating the temperature change caused by an emission.

Yet, HFCs are also extremely harmful to the climate, with global warming potentials much higher than carbon dioxide.

Since methane has a much shorter residence time in the atmosphere than carbon dioxide, but has a greater warming potential over that time, the use of a 20 - year time frame makes methane seem more serious than if a timeframe of 100 years or longer is used.

Hello Alex I read a study a few months ago that says that carbon emissions d'ont take 40 years to reach thei full warming potential, but only 10... I wish I had kept the link though.

A task force of the Ministry calculated that thanks to these alternative solutions, 120 million tons of CO2 - equivalent (a figure for global warming potential measuring how much of a certain greenhouse gas contributes to the greenhouse effect) was eliminated in 2010.

It suggests that replacing HFCs with low global warming potential alternatives would limit this problem.

Yet, despite its widespread use, global warming potential fails to provide an accurate look at how greenhouse gases affect the environment in the short and long - term, according to a team of researchers from Princeton University, the Environmental Defense Fund and Harvard University.

The researchers argue in the May 5 issue of Science that because global warming potential calculates the warming effects of greenhouse gases over 100 years, they discount the effects of any greenhouse gas that disappears from the atmosphere after a decade or two.

The US Global Warming Action Plan, published last October, says the government will «narrow the scope of uses allowed for HFCs with high global warming potential where better alternatives exist».

The additional warming potential is a few watts per square metre of the Earth's surface, or about double the heating effect of all human energy use.

A Japanese study showed that producing a kilogram of beef leads to the emission of greenhouse gases with a global warming potential equivalent to 36.4 kilograms of carbon dioxide (CO2).

Class 14b: Global climate change Basics of global warming Potential effects Politics of global warming.

The workshop addressed, through presentations, subsequent question and answer sessions and general discussion, the following issues: the diversity of nationally appropriate mitigation actions (NAMAs); their underlying assumptions; methodologies, sectors and gases covered; the global warming potential value used; the support needed for NAMA implementation; and the estimated mitigation outcomes.

What is with these deniers such as Chief Hydrologist and Haddad who think that one - time combustion has anywhere near the same effect as the GHG warming potential.

HFCs are synthetic chemicals, primarily used in refrigeration, air conditioning and foam blowing, which were commercialized to replace the high - global warming potential zone - depleting chemicals phased out by the Montreal Protocol over the past 25 years.

The Montreal Protocol has a lot more to offer than a model for addressing global warming emissions, it is itself an important tool that urgently needs to be strengthened to harvest the «low hanging fruit» of phasing out hydrofluorocarbons (and HCFCs), the high global warming potential ODS alternatives with genuinely climate friendly natural refrigerant solutions.

(The latter targets the destruction of a wide range of waste refrigerants and air conditioning substances — which not only deplete ozone, but have profound global warming potential impacts, ranging between 100 and 11,000 times the greenhouse gas potency of carbon dioxide.)
