Sentences with phrase «absorb greenhouse gas emissions»

Forests clean the air, absorb greenhouse gas emissions, and stabilize the climate — both globally and locally.

There are also concerns that oceans, which currently absorb more than 90 percent of the extra heat being trapped by human greenhouse gas emissions, could eventually release some of that back to the surface, speeding up the surface temperature rise.

«To mitigate climate change means to know well where the emissions of greenhouse gases come from and also how natural systems absorb some of them,» Van Ypersele said.

Greenhouse gases absorb intense emission from the surface and re-emit less intense energy at colder temperatures, resulting in an efficient heat trapping mechanism.

The argument for geoengineering goes like this: the world is getting inexorably warmer; governments show no sign of drastically reducing greenhouse gas emissions, so why not control the planetary thermostat by finding a way to filter, block, absorb or reflect some of the sunlight hitting the Earth?

The IPCC scientists agree that much of the heat that humans have put into the atmosphere since the 1970s through greenhouse gas emissions probably has been absorbed by the ocean.

To compensate the temperature of the Earth system has to increase, increasing the rate of emission in regions of the thermal IR where greenhouse gases do not absorb.

When Oreskes quotes, ««Human activities... are modifying the concentrations of atmospheric constituents... that absorb or scatter radiant energy... [M] ost of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas emissions», her quotation is accurate and she actually emphasizes the word likely.

For instance, the long - term warming effects of CO2 and other greenhouse gases are largely buffered by the ocean, which absorbs more than 90 percent of the excess heat caused by human emissions of CO2 and other greenhouse gases.

To address the unavoidable emissions, H&M and WWF will look at measures to strengthen the planet's ability to recover and resist climate change, as well as supporting technological innovations to absorb greenhouse gases.

To achieve the maximum climate benefits of bioenergy in terms of greenhouse gas emissions avoided, the amount of carbon dioxide released during biomass production, processing, transportation and use should be equal to or smaller than the amount that was absorbed by the harvested biomass.

The destruction of natural ecosystems — whether rain forest in the tropics or grasslands in South America — not only releases greenhouse gases into the atmosphere when they are burned and plowed, but also deprives the planet of natural sponges to absorb carbon emissions.

Mitigation refers to an action that will reduce or prevent greenhouse gas emissions, such as planting trees in order to absorb more CO2.

Both wetland drying and the increased frequency of warm dry summers and associated thunderstorms have led to more large fires in the last ten years than in any decade since record - keeping began in the 1940s.9 In Alaskan tundra, which was too cold and wet to support extensive fires for approximately the last 5,000 years, 105 a single large fire in 2007 released as much carbon to the atmosphere as had been absorbed by the entire circumpolar Arctic tundra during the previous quarter - century.106 Even if climate warming were curtailed by reducing heat - trapping gas (also known as greenhouse gas) emissions (as in the B1 scenario), the annual area burned in Alaska is projected to double by mid-century and to triple by the end of the century, 107 thus fostering increased emissions of heat - trapping gases, higher temperatures, and increased fires.

As greenhouse gas emissions increase, billions of tons of carbon dioxide from smokestacks and vehicle tailpipes are absorbed by the oceans.

The results run contrary to a significant body of recent research which expects that the capacity of terrestrial ecosystems and the oceans to absorb CO2 should start to diminish as CO2 emissions increase, letting greenhouse gas levels skyrocket.
