Solar radiation management attempts to
offset effects of greenhouse gases by causing Earth to absorb less solar radiation.
Not exact matches
Overall these aerosol
effects promote cooling that could
offset the warming
effect of long - lived
greenhouse gases to some extent.
Scientists knew about the warming
effects of greenhouse gases, but proponents
of global cooling argued that
greenhouse warming would be more than
offset by Earth's orbital changes.
Some things we might do if we got desperate enough: scrub
greenhouse gasses from the atmosphere technologically, geo - engineering to create cooling
effects to
offset greenhouse heating, [SLIDE 42] lots
of adaptation policies, cropping patterns, heat drought and salt - resistant crops, strengthen public health and environmental engineering defenses against tropical disease, new water projects for flood control and drought management, dyke storm surge barriers, avoiding further development on flood plains in near sea level.
(I think that an anomalously warm ocean surface heated from below would lead to more evaporation, and the additional water vapor would give a positive
greenhouse effect that would partially
offset the
effect of a drop in
greenhouse gas concentrations.)
Multi-signal detection and attribution analyses, which quantify the contributions
of different natural and anthropogenic forcings to observed changes, show that
greenhouse gas forcing alone during the past half century would likely have resulted in greater than the observed warming if there had not been an
offsetting cooling
effect from aerosol and other forcings.
Thus it is entirely unsurprising that these short - term
effects all aligning in the cooling direction in recent years have
offset much
of the surface warming caused by human
greenhouse gas emissions.
As the CO2 and CH4 (methane) level goes up, H2O vapour in the atmosphere falls which — because H2O is 30 times more important than CO2 as a «
greenhouse gas»
offsets the
effect of CO2 on temperature, while cloud cover and albedo increases because warmed moist air rises to form clouds, further cooling the world.
«It isn't the case,
of course, that carbon - emission controls are the only policy response to climate change risks; technologies that furnish a substitute for and that
offset the
effects of greenhouse -
gas - producing energy sources can contribute, too,» wrote Kahan and his colleagues.
Yesterday, we released our annual survey
of the voluntary carbon markets, which takes stock
of what individuals, corporations, and governments have been doing to
offset their
greenhouse -
gas emissions until the Paris Agreement takes
effect — which could happen as early as next year.
Which points out the anemic
effect that U.S.
greenhouse gas reductions will have on the climate
of the U.S. and just how easily the whims
of foreign nations, not to mention Mother Nature, can completely
offset any climate changes induced by our
greenhouse gas emissions reductions.»
By reflecting the sun's rays back to space, these cool materials also release less heat into the atmosphere, thus cooling the planet and
offsetting the warming
effects of substantial amounts
of greenhouse gas emissions.
Declining solar insolation as part
of a normal eleven - year cycle, and a cyclical change from an El Nino to a La Nina dominate our measure
of anthropogenic
effects because rapid growth in short - lived sulfur emissions partially
offsets rising
greenhouse gas concentrations.
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).
16 November 2010 Governors from the US state
of California, the Brazilian state
of Acre, and the Mexican state
of Chiapas have taken concrete steps to reduce
greenhouse gas emissions from deforestation and forest degradation (REDD) by creating a working group designed to help Acre and Chiapas generate REDD credits that can be recognized by California's Air Resources Board (ARB) and sold as
offsets to industrial emitters in California once the state's mandatory cap on
greenhouse gas emissions goes into
effect at the end
of next year.
The resulting simulations show the cooling contribution
of aerosols
offset the ongoing warming
effect of increasing
greenhouse gases over the mid-twentieth century in that part
of the Arctic.
By absorbing less sunlight than either green or black roofs, white roofs
offset a portion
of the warming
effect from
greenhouse gas emissions...
If we add in the warming
effects of the other long - lived
greenhouse gases, the best estimate rises to 1.22 °C surface warming caused by human emissions (we've only observed ~ 0.8 °C warming because much
of that has been
offset by human aerosol emissions).
There is substantial question as to the behavior
of a minute amount
of a trace
gas in an atmospheric / hydrological system the basic
effect of which is to move immense amounts
of heat and moisture from point A to point B. For example, a 10 % reduction in humidity in the upper troposphere is enough to
offset the entire
greenhouse effect of all the atmospheric CO2 above 160 ppm, which is the minimum level needed to sustain life.
