Sentences with phrase «warming pollutants emitted»

We are hopeful that Mr. Trump and his campaign will take a closer look at energy efficiency as an energy resource to promote energy security so that current and future generations are less dependent on imported fuels as well as to ensure that we all have cleaner air to breathe since energy efficiency helps reduce the smog and global warming pollutants emitted from fossil - fueled power plants.

Not exact matches

A study published in ACS» journal Environmental Science & Technology has found that because the newer engines emit higher levels of the climate - warming pollutant black carbon than traditional engines, their impact on the climate is uncertain.

Engineers focused on improving thermal efficiency and reducing friction of the engine's internal moving parts, especially during warm - up — the time when an engine emits higher levels of CO2 and other pollutants.

Given those two factors and ignoring future emissions that will drive the temperature even higher, we are already over +2 C warming once we stop emitting short - lived coal smoke and other pollutants into the air and we give the Earth time to reach temperature equilibrium.

Black carbon — a dangerous pollutant emitted by old, dirty diesel engines like school buses — is thought to be the second largest contributor to global warming after carbon dioxide.

Recent studies including an assessment by the United Nations Environment Program and the World Meteorological Organization indicate that it's possible to slow the pace of warming and melting in the Arctic in the near term by reducing emissions of two common climate pollutants: black carbon and methane, both of which are emitted from the extraction and burning of fossil fuels.

However in John's recent weekly news (28 Dec) the 3rd article (Climate change 2013: Where we are now - not what you think) contained - «The new IPCC report tells us that half of warming (57 %) that should have already occurred has been masked by aerosols mostly emitted since the turn of the century in rapidly developing Asian nations (yes, warming would double if cooling smog pollutants were suddenly cleaned up in Asia).»

«The short - lived climate pollutants [like methane] that we emit from human activities are basically controlling how fast the warming occurs,» she said.

Also contributing to the warmer urban atmosphere is the blanket of pollutants and water vapour that absorbs a portion of the thermal radiation emitted by the Earth's surface.

«Precise measurements of temperature within the ocean confirm that the Earth is absorbing more energy from sunlight than it emits back to space, providing perhaps the strongest evidence to date that rising concentrations of greenhouse gases and other pollutants are the primary cause of the current global warming trend.

Cars, buses, and trucks release pollutants and greenhouse gases that promote warming, while emitting few aerosols that counteract it.

He added that ethanol may also emit more global - warming pollutants than fossil fuels, according to the latest scientific studies.

«Power plants directly emit a long list of harmful pollutants,» the campaign's website says, «and electric utilities also remain the nation's largest industrial source of carbon dioxide, a significant contributor to global warming.»
