Not exact matches

«As powerful as the cycle is, it is also surprisingly susceptible to environmental changes — and humankind is imposing massive perturbations on Amazonia by both cutting down the trees and heating up the air with greenhouse gases, which reduces large - scale moisture transport and precipitation, and end up affecting even the untouched patches of the forests.»

Methane, which can leak from pipelines and valves, is a powerful greenhouse gas, with up to 80 times the potential of carbon dioxide to trap the planet's heat.

The second argument is that it is claimed that computer models are now powerful and accurate enough to replicate temperature given the inputs of greenhouse gas forcing and natural forcing (this is what Nordhaus shows in footnote 4) a graph with both is much more accurate than with just natural forcing.

If nothing else, the White House coordinated today's Rose Garden announcement to start balancing North American greenhouse gas emissions with adequate energy supplies at the center of Canada's powerful energy industry.

In both cases, methane gas bubbles to the surface with little or no oxidation, entering the atmosphere as CH4 — a powerful greenhouse gas which increases local, then Arctic atmospheric and ocean temperature, resulting in progressively deeper and larger deposits of clathrate melting.

Its warming effect, however, is simultaneously amplified and dampened by positive and negative feedbacks such as increased water vapor (the most powerful greenhouse gas), reduced albedo, which is a measure of Earth's reflectivity, changes in cloud characteristics, and CO2 exchanges with the ocean and terrestrial ecosystems.

Of the fossil fuels, natural gas emits less carbon dioxide than oil (though the gas itself, methane, is a powerful greenhouse gas and there are serious leakage problems with its use).

Danger of Undermining Emissions Mitigation Efforts If politicians are led to believe that a low - cost technological fix can reduce or eliminate the need for politically difficult actions such as increasing the cost of carbon by cap and trade schemes or taxation, going against the wishes of powerful fossil energy corporations, and getting countries all around the world to agree on climate goals, it is likely to undermine their resolve to deal with the underlying cause of the problem by reducing greenhouse gas emissions.

Prime Minister Justin Trudeau's plan to replace fossil fuels with ethanol and other low - carbon fuels through a «clean fuel standard» — expected to slash greenhouse gas emissions by 30 million tonnes a year by 2030 — faces mounting opposition, especially from a powerful lobby south of the border.
