Not exact matches

Even the 350 - ppm limit for carbon dioxide is «questionable,» says physicist Myles Allen of the Climate Dynamics Group at the University of Oxford, and focusing instead on keeping cumulative emissions below one trillion metric tons might make more sense, which would mean humanity has already used up more than half of its overall emissions budget.

Instead, what's important is the cumulative emissions of carbon dioxide (CO2)-- since a single molecule of CO2 can linger in the atmosphere for as long as 1,000 years — emitted since the dawn of the industrial era.

His work has shown that limiting cumulative emissions of carbon dioxide may be a more robust approach to climate change mitigation policy than attempting to define a «safe» stabilization level for atmospheric greenhouse gases.

The long - term sea level rise will depend critically on the cumulative carbon emission pathway humans follow, which determines the sustained global warming that can be maintained for centuries to millennia.

In other words — by 2014 we'd used more of the carbon budget than any of the RCPs had anticipated and if we are not confident that the real world is cooler than the models at this level of cumulative emissions, this means that available emissions for 1.5 degrees should decrease proportionately.

Cumulative emissions from producing and burning Canadian oil would use up 16 % of the world's carbon budget to keep temperatures below 1.5 degrees, or 7 % of the budget for 2 degrees.

Regarding text stating that limiting warming from anthropogenic CO2 emissions alone to likely less than 2 °C since 1861 - 1880 requires cumulative emissions to stay below 1000 gigatonnes of carbon (GtC), Saudi Arabia urged using 1850 for consistency, to which the CLAs responded that some model simulations only begin in 1860, which delegates agreed to reflect in a footnote.

While the models get the warming just about right for the current concentrations of CO2, the fact that they tend to have lower estimates of historical emissions means that the carbon budgets based on the relationship between cumulative CO2 emissions and warming tend to be on the low side.

Cumulative carbon dioxide emissions should be calculated on a per capita basis for each country, so that every nation can shoulder a common but differentiated responsibility for climate change... Such a calculation «better reflects the principal of equity for developing countries»...

In order to estimate the cumulative CO2 emissions for use in calculating the carbon budget, ESMs within CMIP5 had to back - calculate emissions based on the atmospheric concentrations using the carbon cycle within each model.

«The proportionality of warming to cumulative emissions depends in part on a cancellation of the saturation of carbon sinks with increasing cumulative emissions (leading to a larger airborne fraction of cumulative emissions for higher emissions) and the logarithmic dependence of radiative forcing on atmospheric CO2 concentration [leading to a smaller increase in radiative forcing per unit increase in atmospheric CO2 at higher CO2 concentrations; Matthews et al. (2009)-RSB-.

Hence, cumulative carbon emissions to 2200 and peak emission rates could provide a clear and simple framework for CO2 mitigation policy.

Translating this commitment into quantitative implications for cumulative carbon involves a lot of guesswork as to how China will go about fulfilling its commitment, because the agreement does not spell out the value at which emissions will peak.

In addition to it's focus on temperature increase, the report also suggests the use of cumulative carbon emissions over time as a valuable metric for linking emissions to impacts.

Overall the G8 pathway has cumulative carbon dioxide emissions (2012 — 2100) of 1,485 Gt CO2 for fossil fuels, and 125 for LUCF, with an additional 45 GtCO2 after 2100 assuming continued exponential decline.

For example, analyses of remaining carbon budgets often use ESM - derived numbers from the Intergovernmental Panel on Climate Change's (IPCC) most recent assessment report, and calculate remaining budgets using observed cumulative emissions to date.

Each molecule of carbon dioxide, which is the most important long - lived manmade greenhouse gas, can remain in the atmosphere for as many as 1,000 years, making it more urgent to cut emissions in the near future, or face continued cumulative warming for centuries to come.

The Carbon Majors website is based on ground - breaking research on 90 entities (investor - owned, state - owned, and government - run fossil fuel and cement producers) that are responsible for producing the fuels that have resulted in 63 percent of the global cumulative emissions of industrial carbon dioxide and methane between 1751 and 2010.

Cumulative carbon emissions, emissions floors and short - term rates of warming: implications for policy

Keeping global average temperatures to 1.4 C would mean cumulative global emissions couldn't exceed around 600bn tonnes of carbon (~ 2,200 bn tonnes of CO2) since pre-industrial times, rather than 850bn tonnes (~ 3,100 bn tonnes of CO2) for 2C, the paper says.
