Sentences with phrase «offset human emissions»

George is convinced that by adding iron sulphate to the oceans, he can stimulate plankton blooms and so suck enough carbon dioxide out of the atmosphere to offset human emissions from burning coal and oil.

Even then, CO2 concentration rises because the stronger sink is still not enough to offset human emissions.

It's is offsetting human emissions.

In other words, the EF defines carbon uptake in forests as the single mechanism for offsetting human emissions of greenhouse gases from industrial activity to the atmosphere.

Not exact matches

The authors of this new research paper analysed data and models from the USEPA's updated global non-CO2 GHG mitigation assessment to investigate the potential for GHG reductions from agricultural emissions from seven regions globally, offsetting costs against social benefit of GHG mitigation (e.g. human health, flood risk and energy costs).

As future climate changes become more severe, people might become interested in ways of offsetting the effects of human - induced climate, which could be cheaper than measures to cut carbon dioxide emissions.

Human aerosol emissions are also offsetting a significant amount of the warming by causing global dimming.

Some wonder if this could be the start of an extended period of solar indolence that would more than offset the warming effect of human - made carbon dioxide emissions.

[Some wonder if this could be the start of an extended period of solar indolence that would more than offset the warming effect of human - made carbon dioxide emissions]

Thus a grand solar minimum would have to cause about 1 °C cooling, plus it would have to offset the continued human - caused global warming between 1 and 5 °C by 2100, depending on how our greenhouse gas emissions change over the next century.

Greenhouse gases can be attributed to about 0.9 °C of this warming, but it has been partially offset by about 0.3 °C cooling from human aerosol emissions.

orgConsider David Keith's idea, presented in an article published in the Proceedings of the National Academy of Sciences, of deploying a fleet of thermostatically self - regulating, mirror - coated, nanotechnology flying saucers, which would be programmed to assemble at the latitude and altitude appropriate to reflect back the precise amount of sun light necessary to offset the global heating associated with human - caused CO2 emissions.

The economic benefit of better air quality, from improved human health and increased yields from agriculture and forestry, can offset costs associated with emissions reductions.

The Advisory Board shall recommend changes to offset methodologies, protocols, or project types, or to the overall offset program under this part, to ensure that offset credits issued by the Administrator do not compromise the integrity of the annual emission reductions established under section 703, and to avoid or minimize adverse effects to human health or the environment.

-- Dot Earth Blog — October 3, 2008 — Expert: Some wonder if this could be the start of an extended period of solar indolence that would more than offset the warming effect of human - made carbon dioxide emissions.

And exactly how much global warming is being offset by human aerosol emissions?

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.

All of these studies find that humans are responsible for close to 100 % of the observed global warming over the past 50 years, and human greenhouse gas emissions are responsible for close to 150 % of the observed warming, with human aerosol (sulfur dioxide - SO2) emissions offsetting approximately one - third to one - half of that greenhouse warming.

A physicist is no more likely than a sociologist to know what human emissions will be 50 years from now — if a slight warming would be beneficial or harmful to humans or the natural world; if forcings and feedbacks will partly or completely offset the theoretical warming; if natural variability will exceed any discernible human effect; if secondary effects on weather will lead to more extreme or more mild weather events; if efforts to reduce emissions will be successful; who should reduce emissions, by what amounts, or when; and whether the costs of attempting to reduce emissions will exceed the benefits by an amount so large as to render the effort counterproductive.

The derivatives since 1960: The variability in sink rate is caused by temperature variability, the offset and slope of dCO2 / dt is caused by human emissions.

It's not a avery large offset to human emissions and I think there bigger concern is that all of this very large reservoir of lake moss peat, this lake carbon, is stored in permafrost since the sediments refreeze when they drain.»

It simply isn't conceivable that a mere 55 % of human emissions, (after deducting the so called airborne fraction) offsets the entire absorption changes caused globally and naturally by warmer ocean surfaces.

If forests globally were to become a net source of carbon to the atmosphere in the future — an all - too - plausible scenario under climate change — the EF would approach infinity, since additional forest would augment human carbon emissions rather than offset them.

Its methodology involves constructing and comparing two separate «accounts,» representing the supply and demand of renewable biological resources across six mutually exclusive land - use types: cropland, grazing land, forest, fishing ground, built - up land, and the area of forest required to offset human carbon emissions (the carbon footprint).

So, in order to trigger another LIA, a new grand solar minimum would have to cause about 1 °C cooling, plus it would have to offset the continued human - caused global warming of 1 to 5 °C by 2100, depending on how our greenhouse gas emissions change over the next century.

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).

That means if plants around the world continue to adjust to rising carbon dioxide concentrations, increasing their biomass on a global scale, they could actually help offset some of our human carbon emissions by removing more carbon dioxide from the air.
