A crucial distinction in the global - warming balance sheet — and another stumbling block for beginners starting to count carbons — is that researchers treat fuel from current plant growth as causing zero net greenhouse - gas emissions.

The researchers [3] quantified China's current contribution to global «radiative forcing» (the imbalance, of human origin, of our planet's radiation budget), by differentiating between the contributions of long - life greenhouse gases, the ozone and its precursors, as well as aerosols.

At the height of the last interglacial, when greenhouse - gas levels were roughly similar to current values, the global sea level was 4 - 6 metres higher than it is today.

Writing in Current Climate Change Reports, they conclude that, the most urgent course of action is to reduce global greenhouse gas emissions, but concurrently there is also a need to consider novel management techniques and previously over-looked reef areas for protective actions under predicted climate change impacts.

So the report notes that the current «pause» in new global average temperature records since 1998 — a year that saw the second strongest El Nino on record and shattered warming records — does not reflect the long - term trend and may be explained by the oceans absorbing the majority of the extra heat trapped by greenhouse gases as well as the cooling contributions of volcanic eruptions.

A new study, published today in Nature Climate Change, suggests that — if current trends continue — food production alone will reach, if not exceed, the global targets for total greenhouse gas (GHG) emissions in 2050.

As a self - proclaimed «climate leader» the UK government has a critical role to play in closing the «emissions gap» — the gap between the current global trajectory of greenhouse gas emissions and the actions necessary to limit warming to 1.5 ˚C and «well below» 2 ˚C (and hence reduce the risks of disaster), they write.

As a self - proclaimed «climate leader» the UK government has a critical role to play in closing the»em issions gap» — the gap between the current global trajectory of greenhouse gas emissions and the actions necessary to limit warming to 1.5?

But if people continue to pump greenhouse gases into the air at current rates, global temperatures could increase by as much as 7.8 °C (about 14 °F) by 2100, the new report points out.

On a related note, is a «runaway greenhouse» effect impossible, given the current data and understanding about global warming?

To derive the climate projections for this assessment, we employed 20 general circulation models to consider two scenarios of global carbon emissions: one where atmospheric greenhouse gases are stabilized by the end of the century and the other where it grows on its current path (the stabilization [RCP4.5] and business - as - usual [RCP8.5] emission scenarios, respectively).

A recent study by Utah State University scientists found a possible link, but other researchers have been reluctant to pin the current drought on the rise in global greenhouse gas emissions.

Current management practices in the land use sector are responsible for approximately 25 per cent of the global greenhouse gas emissions.

Without mitigation of emissions, we may generate greenhouse gas concentrations and global temperatures more akin to those of the early Paleogene, over forty million years ago, than those of the current geological period, the Neogene.

Based on current scientific understanding, this requires that global greenhouse gas emissions need to be reduced by at least 50 % below their 1990 levels by the year 2050.

Specifically, do you believe current global warming is caused by GCR's and thereby greenhouse gases are unimportant?

«A rapid cutback in greenhouse gas emissions could speed up global warming... because current global warming is offset by global dimming — the 2 - 3ºC of cooling cause by industrial pollution, known to scientists as aerosol particles, in the atmosphere.»

Justin Gillis has filed a post on the Green Blog summarizing the main points in a new and voluminous draft federal report on current and anticipated impacts from greenhouse - driven global warming on the United States.

Second, «always» is forever, but ice isn't, especially since on our current greenhouse gas emissions path, we may see more than 5 °C global warming this century.

I don't think I try to poke holes at the idea that Arctic warming is «likely driven in part by the global greenhouse effect» but I do seek out weaknesses with suggestions that it is driven entirely, or to some very large degree, by a human - enhanced greenhouse effect (at least at the current time).

although the experts are divided on what mix of forces is in play — from winds to warm currents to the underlying warming of the global climate from accumulating greenhouse gases.»

Many think so, although the experts are divided on what mix of forces is in play — from winds to warm currents to the underlying warming of the global climate from accumulating greenhouse gases.

But I do agree with the Breakthrough point that an overemphasis on current events as the reason to pursue the decades - long task of shifting global greenhouse emissions trajectories can backfire, and in more ways than they describe.

In the standards for middle school, for example, one of the core ideas is that «human activities, such as the release of greenhouse gases from burning fossil fuels, are major factors in the current rise in Earth's mean surface temperature («global warming»).»

Although APS plans to reduce its coal burn from the current 35 % to 17 % by 2029, by increasing its natural gas burn from 19 % to 35 %, it will actually increase its greenhouse gas emissions in the near term, since the global warming potential from methane, which is leaked at multiple points of the natural gas supply chain, is 86 times that of carbon over 20 years, according to the Intergovernmental Panel on Climate Change's 2013 report.

Kevin Hamilton, who co-authored the report, warns: «If our model results prove to be representative of the real global climate, then climate is actually more sensitive to perturbations by greenhouse gases than current global models predict, and even the highest warming predictions would underestimate the real change we could see.»

And if you look at the current rapid rise in global greenhouse - gas emissions, we'll likely put enough carbon dioxide in the atmosphere by mid-century to surpass the 2 °C limit — and soar past the 4 °C limit by century's end.

However, current estimates of lake level changes are uncertain, even for continued increases in global greenhouse gas emissions (A2 scenario).

If the Earth stays on its current course without reversing greenhouse gas emissions, and global temperatures rise 5 degrees Celsius, as scientists say is possible, the pace of change will be at least 50 times and possibly 100 times swifter than what's occurred in the past, Field said.

Continued greenhouse gas emissions at or above current rates would cause further warming and induce many changes in the global climate system during the 21st century that would very likely be larger than those observed during the 20th century.

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.

This technical document provides the following information: - An update of global greenhouse gas emission estimates, based on a number of different authoritative scientific sources; - An overview of national emission levels, both current (2010) and projected (2020) consistent with current pledges and other commitments; - An estimate of the level of global emissions consistent with the two degree target in 2020, 2030 and 2050; - An update of the assessment of the «emissions gap» for 2020; - A review of selected examples of the rapid progress being made in different parts of the world to implement policies already leading to substantial emission reductions and how they can be scaled up and replicated in other countries, with the view to bridging the emissions gap.

This technical document presents the latest estimates of the emissions gap in 2020 and provides plentiful information, including about current (2010) and projected (2020) levels of global greenhouse gas emissions, both in the absence of additional policies and consistent with national pledge implementation; the implications of starting decided emission reductions now or in the coming decades; agricultural development policies that can help increase yields, reduce fertilizer usage and bring about other benefits, while reducing emissions of greenhouse gases; and, international cooperative initiatives that, while potentially overlapping with pledges, can complement them and help bridge the emissions gap.

This is so because the world will need to reduce global greenhouse gas emissions from current levels by 80 % or greater by the middle of this century to prevent catastrophic climate change as greenhouse gas emissions increase world wide increase at 2 % per year under current trends.

The Climate Scoreboard calculates the long - term global temperature rise if all the current national proposals to reduce greenhouse gas emissions were implemented.

WASHINGTON — A sobering new report warns that the oceans face a «fundamental and irreversible ecological transformation» not seen in millions of years as greenhouse gases and climate change already have affected temperature, acidity, sea and oxygen levels, the food chain and possibly major currents that could alter global weather.

Internal variability has always been superimposed on top of global surface temperature trends, but the magnitude - as well as the fingerprints - of current warming clearly indicates that anthropogenic greenhouse gases are the dominant factor.

At current production rates, high - carbon tar sands oil and its byproducts throw off enough greenhouse gas emissions to mark Canada as an obstacle to stopping global warming short of catastrophic levels.

Thus, the hypothesis of current global warming as a result of increased emission of carbon dioxide (greenhouse gases) into the atmosphere is not true.
