This year’s edition highlights the growing divergence between demands for action on climatechange and the actual pace of progress on reducing carbon emissions.
A new study published in Nature Communications by researchers from IIASA, Boston University, and the Ca’ Foscari University of Venice found that by mid-century, climatechange will increase the demand for energy globally, even with modest warming.
The gap, noted the researchers in their open-access paper in Nature ClimateChange , is equivalent to Japan’s annual CO 2 emissions, the world’s fourth largest emitter, with 5% of the global total. The dashed line represents the aggregated CO2 emissions calculated from the provincial energy statistics 1997–2010.
Published in the journal Nature ClimateChange , the new analysis shows fossil fuel emissions increased by 5.9% Global CO 2 emissions since 2000 are tracking the high end of the projections used by the Intergovernmental Panel on ClimateChange, which far exceed two degrees warming by 2100. parts per million.
These findings, published in Nature ClimateChange , are contrary to results of some earlier work on this subject. Extreme value theory , used in science, engineering, insurance and risk management, provides a theoretical foundation for building statistical models describing extreme events. —Auroop Ganguly. Shih-Chieh Kao.
Under benchmark risk management metrics, allowable emission paths should have less than a 10% chance of overshooting the target, Lemoine notes in a new paper published in the American Meteorological Society’s Journal of Climate , so policymakers “ may therefore require significant near-term abatement and eventual net negative emissions.
The report for the Department for Transport is based on a survey module included in the Office for National Statistics’ Opinions (Omnibus) survey which has been carried out each August since 2006. It found that 65% of respondents spontaneously selected emissions from road transport as a cause of climatechange.
Using a variety of data including direct observations, computer-generated models, and estimates from countries’ energy statistics, the team created a global CO 2 budget—the amount of CO 2 produced and consumed—from 1959 to 2008. Tags: ClimateChange Emissions. over the previous seven years. —Dr Canadell.

Decomposition of the decadal change in total global CO 2 emissions from fossil fuel combustion by four driving factors; population, income (GDP) per capita, energy intensity of GDP and carbon intensity of energy. However, the underlying estimates do not take into account economic benefits of reduced climatechange.
The wisdom of crowd effect is a statistical phenomenon and not a social psychological effect, because it is based on a mathematical aggregation of individual estimates. Therefore, social influence can also have an impact on the statistical aggregate and the resulting collective wisdom of the respective crowd. —Lorenz et al.

GEOS-Chem captures observed seasonal trends with no statistically significant difference between simulated and measured mean annual concentrations. Once they mix with other chemicals, it’s unknown what danger they could pose to animals and humans, especially in concert with climatechange stressors in the Arctic.
While CO 2 emissions are likely important for estimating global climatechange impacts, a recent report on the climatechange potential of aviation suggests that emissions other than CO 2 , including soot and NO x , need to be included in forecasts of potential aviation induced global climatechange.
The report is based on recent results from the joint JRC/PBL Emissions Database for Global Atmospheric Research (EDGAR), the latest statistics on energy use and various other activities. According to national statistics, in 2013 total oil consumption in transport increased somewhat by 0.5%, relative to 2012 levels. billion tonnes (Gt).
A paper and subsequent formal comments and responses in the journal ClimaticChange highlights the conceptual differences and the impact on policy. In a Commentary published in ClimaticChange , Robert De Kleine and his colleagues argue that the assumptions used by DeCicco and his colleagues are invalid. earlier post ).
Researchers at the University of California, Irvine and other institutions have conducted a statistical analysis of pollution exposure and yields from 1980 to 2015 on a key sector making up about 38% of the state’s total agricultural output: perennial crops such as almonds, grapes, nectarines, peaches, strawberries and walnuts. Mueller, N.D.,
The authors compared cloud properties inside the shipping route with an estimate of what those cloud properties would have been in the absence of shipping based on statistics from nearby, unpolluted areas. However, if this small change occurred worldwide, it would be enough to affect global temperatures. C, or 1.8 ?F,
The findings, published in the 21 September issue of Atmospheric Chemistry and Physics , are generally consistent with official Chinese government statistics and could bolster their credibility as international negotiations proceed on commitments of China and other nations to combat climatechange. Munger, J. McElroy, M.
The IEA’s chief economist recently estimated that eliminating all subsidies in 2012 for coal, gas, and oil could save as much as Germany’s annual greenhouse gas emissions each year by 2015, while the emission savings over the next decade might be enough to cover half of the carbon savings needed to stop dangerous levels of climatechange.
Many projections of future greenhouse gas (GHG) emissions and subsequent warming trends, particularly those used by the United Nations Framework Convention on ClimateChange (UNFCCC), assume a constant airborne fraction to 2100. Tags: ClimateChangeClimate models Emissions Land use. Earlier post.)
EDGAR used the latest international statistics and data on greenhouse gas emissions to model emissions for every country in the world. The EDGAR database fills a gap in current greenhouse gas statistics as it gives consistent information on both industrialized and developing countries.
The Intergovernmental Panel on ClimateChange (IPCC) recommends an overall 40% to 70% reduction in GHG emissions from 2010 levels by 2050. The researchers combined data from trade organizations, governmental scientific agencies and academic literature with monetary trade statistics and their own bottom-up estimates.

Munich Re and climatechange. In 2010 prior to the world climate summit, Munich Re drew attention to the number and scale of weather-related natural catastrophes in the first nine months of that year: floods in central Europe, wildfires in Russia, widespread flooding in Pakistan. There was also widespread ground deformation.
The increase is due mainly to the simulated rise in wildfire frequency in the future, warmer climate. Previous studies by other researchers have probed the links between climatechange and fire severity in the West and elsewhere. Source: Spracklen et al. Click to enlarge. Jennifer Logan. Resources.
