"We've been using your excellent services for about two years," she tells the librarian in a high, warm voice when it's her turn.
Never use a high (warm) setting, and always keep your blow-drier far enough away from your ear.
These systems typically use HFC-134a, which has a high global warming potential.
"In a high global warming world, more people would be better off with geoengineering, but some people would be worse off," he said.
Such systems operate both at medium temperature (MT), i.e. [−5 10]°CC, and low temperature (LT), i.e. [−25 −15]°CC, and they are originally designed to work with hydrofluorocarbon (HFC) R404a, known as a high global warming potential (GWP) fluid (GWP = 3922).
A system performance comparison is conducted for three refrigerant fluids: (i) a banned refrigerant (R12); (ii) its original ozone depletion harmless substitute, but with a high global warming potential, GWP (R134a), and (iii) one of the current substitutes of R134a, i.e., R1234yf.
Summer temperatures in Luliang follows the same trend as Yunnan, but winter temperatures show a slightly higher warming trend than the provincial average, indicating that Luliang is slightly more vulnerable to drought.
They reported an increase in the Brewer-Dobson circulation in the presence of a low-latitude warming and a decrease in the presence of a high-latitude warming extending to the subtropics.
Even if one accepts the estimates advocated by some of a higher "global warming potential" for methane by a factor of approximately three, the increase in climate forcing by methane is significantly smaller than for carbon dioxide.
Cooking with unsustainably harvested biomass can affect climate because inefficient fuel combustion releases products of incomplete combustion with a higher global warming potential than carbon dioxide, such as methane and carbon monoxide (Sagar and Kartha 2007).
