Sentences with phrase «beyond human emissions»

Not exact matches

Since meaningful diminution of global CO2 emission is either technologically impossible or is beyond the amount of sacrifice that the human race is willing to undertake, why does the IPCC absolutely refuse to even consider looking into means to counteract the effect of CO2?

Beyond the problems of the high margin of error of shortwave albedo measurements, and the lack of a counter-factual on precisely and accurately what albedo has been and what it would be in the absence of humans, SO2 emissions globally appear to have peaked:

So I say it is beyond reasonable doubt that human CO2 emission is the most important perturbation in the climate in at least half a million years.

Manacker asserts «[Hansen groupies] know beyond a shadow of a doubt that there could not have been accelerated sea level rise prior to industrial human CO2c emissions.»

Deforestation has caused even more human emissions beyond the emissions from fossil fuel use, but the response of the biosphere can be deduced from the oxygen balance.

Its revised projection indicates that if we stick with business as usual, in terms of carbon dioxide emissions, average surface temperatures on «Earth by 2100 will hit levels far beyond anything humans have ever experienced.

Reductions in some short - lived human - induced emissions that contribute to warming, such as black carbon (soot) and methane, could reduce some of the projected warming over the next couple of decades, because, unlike carbon dioxide, these gases and particles have relatively short atmospheric lifetimes.The amount of warming projected beyond the next few decades is directly linked to the cumulative global emissions of heat - trapping gases and particles.

The US apparent unwillingness to reduce its greenhouse gas emissions beyond what it is already on track to achieve is of considerable controversy in the Qatar negotiations this week because of the growing scientific concern about the potential inevitability of catastrophic warming caused by human activities.

Beyond the scientific questions — it becomes a question of how to pragmatically reduce human pressures on Earth systems — including inter alia — greenhouse gas emissions.

The main evidence for catastrophic anthropogenic global warming (CAGW), the principal alleged adverse effect of human emissions of carbon dioxide (CO2), is climate models built by CAGW supporters in a field where models with real predictive power do not exist and can not be built with any demonstrable accuracy beyond a week or two because climate and weather are coupled non-linear chaotic systems.

-- Volcanoes and vents emit less than 1 % of human emissions (even the Pinatubo eruption caused a dip in the CO2 increase, as the cooling by the volcanic dust increased the absorption of the oceans beyond the extra emissions.

They believe the study supports their view that carbon emissions produced through human activity continue to warm the Earth far beyond what the planet can handle naturally.

The likely outcome is that global warming will produce significantly increasing CH4 emissions beyond human control (unlike farming and industrial emissions) and well beyond the capacity of hyroxils to oxidise.

And if we don't take urgent action NOW to quickly end our GHG emissions and draw down the already dangerous anthropogenic excess CO2, then AGW is likely to have horrific effects on the entire biosphere that will go far beyond merely ending human civilization.
