Contribution of CO2 emitted to the atmosphere by diffuse degassing from volcanoes: The Furnas Volcano case study
Furnas Volcano is a dormant central volcano located in the eastern part of São Miguel Island (Azores archipelago, Portugal). The last volcanic eruption in this volcanic system took place in 1630 causing about 200 victims. Present–day activity comprises fumarolic fields, thermal and cold CO2–rich springs and soil diffuse degassing areas. CO2 diffusely released from the volcano soils was estimated ...

World’s Carbon Budget to Be Spent in Three Decades
The Intergovernmental Panel on Climate Change’s (IPCC) Fifth Assessment Report (AR5) has delivered an overwhelming consensus that climate change impacts are accelerating, fueled by human-caused emissions. We may have just about 30 years left until the world’s carbon budget is spent if we want a likely chance of limiting warming to 2 degrees C. Breaching this limit would put the world ...

Greenhouse gas mitigation in the UK: An overview of the current policy landscape
Domestic legislation – the Climate Change Act 2008 – commits the United Kingdom to an 80 percent emission reduction by 2050 on 1990 levels, and to a system of 5-year carbon budgets to progress toward that target. These carbon budgets require UK emission reductions on 1990 levels of 34 percent by 2020 and 50 percent by 2025. The Carbon Plan, published in December 2011, sets out the UK ...

Soil carbon dynamics and carbon budget of newly reconstructed tall-grass prairies in south central Iowa
Received for publication February 16, 2009. In addition to their aesthetic and environmental qualities, reconstructed prairies can act as C sinks and potentially offset rising atmospheric CO2 concentration. The objective of this study was to quantify C budget components of newly established prairies on previously cultivated land. Net ecosystem production (NEP) was estimated using a C budgeting ...

India’s contribution in carbon emissions – a case study on Delhi region
Global warming due to increase in green house gases especially carbon dioxide has changed the earth’s climate forever. Therefore, this paper is an attempt to find how much does Delhi contribute to global warming? And what role should India play in solving this problem? The study reveals that the major cause of increase in green house gases in Delhi is because of the increased number of vehicles ...

Carbon management for business; A beginner`s guide
Climate change and carbon foot printing are current and real issues for business today. We face many challenges in a world where average temperatures and sea levels continue to rise, affecting food chains, human populations, biodiversity and even insurance premiums. Business can connect on this issue via established environmental management systems such as ISO14001 or BS8555. Whilst carbon ...

Research Article: The Biophysical Role of Water and Ice Within Permafrost Nearing Collapse: Insights from Novel Geophysical Observations
Plain Language Summary: “Changes in the amount of water and ice below the surface, in both space and time, influence high latitude boreal ecosystems across many scales—from microorganisms living within the soils to the health and stability of aboveground plant, animal, and human communities. Warming temperatures and changes in precipitation have the potential to significantly weaken ...

Delaying substantial emission reductions limits climate policy choices
If fast and substantial reduction in greenhouse gas emissions is postponed further, there are fewer options available to stay below the 2 °C warming target for the end of the century. Delayed action is likely to require measures that remove CO2 from the atmosphere by planting forests and using bioenergy in combination with carbon capture and storage. The latter technique still involves ...

Actively aerated methanobiofilters to control methane emissions from landfills
Methane (CH4) capture at sanitary landfills for energy recovery is capable of reducing the impact of CH4 on the global atmospheric carbon budget. However, gas capture may only be viable where gas quantities are high enough to warrant economical energy production. Considering the potential global warming impacts, there is a need to identify alternative methods to control landfill CH4 emissions to ...

Government ignores carbon emission reductions during recession
DECC remains confident that existing plans to cut carbon emissions by 2020 will serve to achieve carbon targets, reports Envido. In its response to the first annual report from the independent Committee on Climate Change (CCC), the government accepted the committee's recommendation to effectively ignore carbon emission reductions that have been achieved as a result of the economic downturn. The ...

The Great Climate Disconnect
GE has asked the members of its Citizenship Advisory Panel to reflect on trends and key challenges for sustainable development in 2013. This first post by Nick Robins tackles the gap between climate change risk and ambition. The year ahead will be dominated by growing tension between ever-stronger evidence of climate change and the inadequacy of the global policy response. Drought in the USA in ...

Carbon Dioxide Emissions from Fossil Fuels and Cement Reach Highest Point in Human History
We already know the world’s carbon budget is being exhausted at an alarming pace, but a new scientific assessment reveals just how sobering the picture of the global carbon cycle truly is. The Global Carbon Project’s (GCP) 2013 report finds that at the precise time emissions reductions are needed most, carbon dioxide (CO2) emissions from burning fossil fuels and producing cement have ...

Reduction in greenhouse gas emissions from sewage sludge aerobic compost in China
Sewage sludge is an important contributor to greenhouse gas (GHG) emissions and the carbon budget of organic solid waste treatment and disposal. In this case study, total GHG emissions from an auto-control sludge compost system, including direct and indirect emissions and replaceable reduction due to sludge compost being reused as fertilizer, were quantified. The results indicated that no ...

Paris Climate Change Agreement: What next?
The Paris Climate Change Agreement took a huge leap forward on 3 September when the world's two biggest economies and emitters of greenhouse gases – the USA and China – announced that they would formally ratify the accord. This brings hope that the deal will be concluded this year. It also piles pressure on the UK to swiftly formalise its commitment to a contract it shaped and take ...
