They include less wait time at toll booths, reduced greenhouse gas emissions and fewer accidents.

Such so - called in situ production requires less water but far more energy to get the bitumen flowing, resulting in greenhouse gas emissions some 2.5 times higher than those from mining.

It says nations will have to impose drastic curbs on their still rising greenhouse gas emissions to keep a promise made by almost 200 countries in 2010 to limit global warming to less than 2 degrees Celsius (3.6 Fahrenheit) over pre-industrial times.

It produces less carbon dioxide emissions than coal for electricity or gasoline and diesel for fuel, but even a small amount of natural gas release — which is essentially methane — packs a greenhouse gas punch about 30 times more powerful than the same amount of carbon dioxide.

It turned out things were far more nuanced (as he later said, «The Earth system may be less responsive in the warm times than it was in the cold times»), but in a field that had long mainly foreseen smooth curves for planetary change with rising greenhouse gas levels, the result was a vital focus on the risks of abrupt climate change.

Eating a plant - based diet was presented in the form of moderate - impact actions such as eating less meat, even though a completely plant - based diet can be 2 to 4.7 times more effective at reducing greenhouse gas emissions than decreased meat intake.

Less well known is the immense potential of soils to act as vast carbon sinks, with the ability to «naturally turn over about 10 times more greenhouse gas on a global scale than the burning of fossil fuels.»

In times when the oceans are warming, there could be several factors that influence this, each with varying contributions based on natural and / or anthropogenic variability: 1) Greater solar output 2) Less aerosols in the atmosphere 3) Less cloudiness (especially of a certain type) 4) Increased greenhouse gases

«causes of the earlier warming are less clear since this period precedes the time of strongest increases in human - induced greenhouse gas (radiative) forcing.»

While the latter warming is often attributed to a human - induced increase of greenhouse gases, causes of the earlier warming are less clear since this period precedes the time of strongest increases in human - induced greenhouse gas (radiative) forcing.»

Although this concentration is far less than that of CO2, methane is 30 times as potent a greenhouse gas and so may now be responsible for 15 — 20 % of the predicted global warming.»

This decline is one - third less than the decline experienced by the nation as a whole, which saw greenhouse gas emissions drop 9.3 percent during the same time period.

ECCC, less focused on protecting the environment than on meeting its 2018 and 2019 deadlines for implementing the clean fuel standard, effectively told them to buzz off, saying it «may make updates to the emissions calculations to reflect indirect greenhouse gas emissions at a future time.»

That's right, the latest climate science (some 10 studies published in just the past 3 years) indicates that the earth's climate sensitivity — that is, how much the global average surface temperature will rise as a result of greenhouse gases emitted from human activities — is some 33 percent less than scientists thought at the time of the last IPCC Assessment, published in 2007.

With the greenhouse gases already accumulated in the atmosphere, it would take less than 30 years for it to be inevitable that temperature would in time reach 2 °C above the pre-industrial level if the global greenhouse - gas emissions stayed at their current rate.

Waste heat is currently responsible for about 100 times less global warming than carbon dioxide and other greenhouse gases.

At this time, there will be a lesser offset of the positive greenhouse effects of the halocarbons and the other well - mixed greenhouse gases (WMO, 1999).

CalCars» mission is to narrow the cost gap through incentives, subsidies and rebates while making the case for paying extra to gain access to car - pool lanes, spend less time at gas stations, get home backup power, lower maintenance costs, and, most importantly, benefit society by reducing oil imports, greenhouse gases and pollution.

'' [Cities] require less time, money, fuel and greenhouse gas emissions for residents to meet their everyday travel needs.

Answer: The forcing of greenhouse gases is counteracted by about 1 Watt / m2 of aerosols, leaving us with 1.5 W / m2 or thereabouts, or less than half that of a doubling of CO2 (3.7 W / m2), and thermal inertia cuts that by half again for the high end sensitivities, and not much of a cut is required for the low end sensitivites (1.5 C times fraction of forcing 1.5 / 3.7 giving about 0.6 C).

CO2 better than HFC Instead of HFC, the machines use CO2, which in this case they estimate to be 1,300 times less potent a greenhouse gas than HFC (over a certain interval of time, the measurement is also known as GWP, or global warming potential).

This means that the impact of greenhouse gases can accumulate and intensify over time, while the aerosol effects become comparatively less important on longer time scales due to the accumulation of carbon dioxide.
