This objective presents challenges because many offsets are difficult to measure. From a global climatechange perspective, it does not matter where or from what source the reduction occurs: the effect on the atmospheric concentration of GHGs would be the same. CREDIBILITY OF OFFSETS. Assuming the offset is legitimate—i.e.,
A study published in Nature ClimateChange suggests that thermoelectric power plants (i.e., nuclear and fossil-fueled generating units) in Europe and the United States are vulnerable to climatechange due to the combined impacts of lower summer river flows and higher river water temperatures. 19% in Europe and 4.4—16%
The Royal Society, the UK’s national academy of science, has published a new short guide to the science of climatechange. The guide summarizes the evidence and clarifies the levels of confidence associated with the current scientific understanding of climatechange. Future climatechange.
Population growth, limits to arable land and fresh water, and climatechange have “ profound implications ” for the ability of agriculture to meet this century’s demands for food, feed, fiber, and fuel while reducing the environmental impact of their production. ” —Federoff et al. —Federoff et al.
Noting the references in scientific and policy literature to the need for fast-action mitigation to help avoid DAI and abrupt climatechanges, the authors define “fast-action” to include regulatory measures that can begin within 2–3 years, be substantially implemented in 5–10 years, and produce a climate response within decades.

” Bunker spent the bulk of his presentation describing the new medium- and heavy-duty fuel economy and greenhouse gas regulations from EPA and the Department of Transportation. While many over time have grown dismissive of radical new engine ideas, remember that they have the opportunity to change the dynamic.we Earlier post.)
Other climate variables used in the analysis are sea surface temperature (SST), sea-level pressure (SLP) from the Hadley center, and vertical velocity, surface winds, and lower tropospheric static stability (potential temperature at 700 mb minus surface temperature) from the ERA-40 reanalysis. a positive feedback). a positive feedback).
It is an unpalatable truth that unless we can succeed in greatly reducing CO 2 emissions we are headed for a very uncomfortable and challenging climate future, and geoengineering will be the only option left to limit further temperature increases. Professor John Shepherd, chair of the Royal Society’s geoengineering study.
Developing technology to address the causes of climatechange, mitigate its impact, and adapt to the crisis is one of IEEE’s top priorities. To assist with that effort, the IEEE Young Professionals group this year launched its Climate and Sustainability Task Force. On 12 September, CSTF and IRENA presented a Youth Day event.

ClimateChange Europe Policy Power Generation'
In other words, the findings suggest that policymakers should be paying more, rather than less, attention to tackling climatechange in economically tough times. A paper on the study was published in the journal Nature ClimateChange. Governments are abandoning climate action as they focus on reviving their economies.
One of the UK’s leading climate scientists has presented new research findings on the increasing potential for a 4 degrees Celsius (7.2 °F) Dr Richard Betts, Head of Climate Impacts at the UK Met Office Hadley Centre, presented the findings at a special conference called “ 4 degrees and beyond ” at Oxford University.
IEEE continues to raise its visibility as a trusted voice on mitigating the effects of climatechange. ClimateChange Conference (COP29). Then in December, IEEE and the International Telecommunication Union held a symposium on achieving climate resilience. Rahman was the events general chair.
The report is not a comprehensive scientific assessment, the authors note; one such is slated to be forthcoming from the Intergovernmental Panel on ClimateChange (IPCC) in 2013–14 in its Fifth Assessment Report. Indeed, present emission trends put the world plausibly on a path toward 4°C warming within the century.
You say you’d like to see that presentation? Here it is as presented to the Green Task Force. He did so on behalf of his son, Carter: You know, I liked Robert’s hyperbolic intro of me so much I’m going to repeat it at the top of this footage of your ever present Creative Greenius addressing the board.
According to the ITF Transport Outlook 2021 , the biennial flagship report of the International Transport Forum, a sister organization of the OECD, global transport activity will more than double by 2050, and traffic emissions will rise by 16% compared to 2015 even if existing commitments to decarbonize transport are fully implemented.
Internationalclimate negotiations can only go so far. Systems such as pledge-and-review set up in Copenhagen and Cancun are a useful way forward in the absence of an internationally legally-binding agreement, but individual Governments must provide urgent political leadership—that is not happening at present.
Aerosol impacts on cloud processes via this pathway are known as aerosol indirect effects, referred to as aerosol-cloud interaction in the most recent Intergovernmental Panel on ClimateChange report. Aerosol impacts are a key uncertainty in understanding the current and future climate as well as extreme weather.
Bethan Owen and colleagues note that aviation is not now one of the main drivers of global warming, with international aviation (the source of 60% of carbon dioxide emissions from aircraft) not even included in the Kyoto Protocol. Tags: Aviation ClimateChange Emissions. Owen et al. Technol. ,
Our results suggest that gas-aerosol interactions play an important role in methane’s GWP, and hence our larger value would allow better optimization of climatechange mitigation policies. Methane’s GWP may also change with time as air quality regulations alter the background state of tropospheric chemistry. Shindell et al.
” A Eurobarometer poll conducted in August and September found that almost nine out 10 EU citizens believe climatechange is a serious problem, with 63% convinced that it is a very serious issue. Now we can.”
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 findings are presented in an open-access paper in Nature Communications. China will reach carbon emission peak before 2030 and carbon neutrality by 2060, and large cities with a significant greening trend play an important role in neutralizing carbon emission and mitigating the impact of global climatechange in urban areas.
Although food security is a longstanding issue, the world needs to confront a new set of challenges such as climatechange, competition for land from bioenergy production, heightened water scarcity, and possible shortfalls of phosphorus for fertilizer. Greater Risk than Necessary?
million by 2030 if the UK is to achieve its climatechange targets. The study suggests that biofuels should be considered a last resort for sectors where at present there are no practical alternatives to fossil fuels, such as aviation, shipping and heavy goods transport.
Moreira’s technology also helps to track the effects of climatechange. By collecting more detailed information, we can better understand, for example, how the forests are changinginternally by imaging every layer,” he says, referring to the emergent layer and the canopy, understory, and forest floor.
