Sentences with phrase «climate over the next several decades»

Not exact matches

Officials from 195 countries, from giants like the U.S. to the tiniest impoverished states, agreed on the world's first global climate - change deal on Saturday evening, committing the world to drastically cutting back carbon emissions and transforming the planet's energy mix over the next several decades.

Finally, the presence of vigorous climate variability presents significant challenges to near - term climate prediction (25, 26), leaving open the possibility of steady or even declining global mean surface temperatures over the next several decades that could present a significant empirical obstacle to the implementation of policies directed at reducing greenhouse gas emissions (27).

While it is worth continuing study of global climate engineering to control warming if the rising concentrations of GHGs can not be halted over the next several decades, the potential for climate engineering approaches to moderate impacts in the particularly exposed regions being affected merits investigation.

With global GHG emissions and concentrations continuing to increase; with climate change intensifying changes in ecosystems, ice sheet deterioration, and sea level rise; and with fossil fuels providing more than 80 % of the world's energy, the likelihood seems low that cooperative actions will prevent increasingly disruptive climate change over the next several decades.

One reason for this is that many impacts of climate change are expected to be proportional to the amount of global average warming that occurs over the next several decades to centuries.

A new assessment by the Intergovernmental Panel on Climate Change (IPCC) concludes that the world community could slow and then reduce global emissions of greenhouse gases (GHGs) over the next several decades by exploiting cost - effective policies and current and emerging technologies.

«Finally, the presence of vigorous climate variability presents significant challenges to near - term climate prediction (25, 26), leaving open the possibility of steady or even declining global mean surface temperatures over the next several decades that could present a significant empirical obstacle to the implemen - tation of policies directed at reducing greenhouse gas emissions (27).

Over the next several decades, almost all of the power plants in the U.S. will need to be replaced, and America's dependence on fossil fuels presents serious national security concerns — they sap our economy, exacerbate climate change, and constrict U.S. foreign policy.

Fast action to reduce short - lived climate pollutants (SLCPs) could slow the rate of global warming while saving millions of lives over the next several decades from air pollution — which now kills more than 6 million people a year.

A 2013 study modeled climate and water system (hydroclimate) changes in the Western US over the next three decades and found that increased temperature is the dominant factor, likely leading to several hydroclimate changes, including: decreases in spring snow pack, increases in cold - season days above freezing, and decreases in the cold - season snow - to - precipitation ratio.

While much of the work on whole - ecosystem regime shifts has focused on drylands, a growing body of evidence indicates abrupt state shifts will plausibly affect many other ecosystems as climate continues to change over the next several decades.

Meeting the ambitious climate change targets agreed upon in Paris last December will require deep transformation of the global economy — especially in energy systems, transportation systems, and industry — over the next several decades.
