Assessing potential climate effects of natural gas versus coal electricity generation is complicated by the large number of factors reported in life cycle assessment studies, compounded by the large number of proposed climate metrics. Thus, there is a need to identify the key factors affecting the climate effects of natural gas versus coal electricity production, and to present these climate effects in as clear and transparent a way as possible.

The world will have to completely phase out fossil fuels in electricity generation by the end of this century and reduce their use to 20% by 2050 if disastrous consequences of climate change are to

Livestock is poorly represented in N budgets for the African continent although some studies have examined livestock-related N flows at different levels. Livestock plays an important role in N cycling and therefore on N budgets including livestock-related flows. This study reviews the literature on N budgets for Africa to identify factors contributing to uncertainties. Livestock densities are usually modelled because of the lack of observational spatial data.

Future sea level rises could put more than $200 billion of Australian infrastructure at risk, a report by the Climate Council has found. The report, Counting the Costs: Climate Change and Coastal Flooding, showed sea levels were likely to rise by between 40 centimetres and one metre over the next century.

Coal-fired power plants are the single biggest global source of greenhouse gas emissions. Coal is the dirtiest fuel and global coal reserves represent a greater source of potential CO2 than any other fossil fuel.

Livestock-based food production is an important and pervasive way humans impact the environment. It causes about one-fifth of global greenhouse gas emissions, and is the key land user and source of water pollution by nutrient overabundance. It also competes with biodiversity, and promotes species extinctions. Empowering consumers to make choices that mitigate some of these impacts through devising and disseminating numerically sound information is thus a key socio environmental priority.

BEIJING: China could set a new pace for slow-moving international climate talks by bringing its domestic commitment to fight global warming on to the world stage, the EU's top climate change offici

The terrestrial ecosystems of North America have been identified as a sink of atmospheric CO2 though there is no consensus on the magnitude. However, the emissions of non-CO2 greenhouse gases (CH4 and N2O) may offset or even overturn the climate cooling effect induced by the CO2 sink. Using a coupled biogeochemical model, in this study, we have estimated the combined global warming potentials (GWP) of CO2, CH4 and N2O fluxes in North American terrestrial ecosystems and quantified the relative contributions of environmental factors to the GWP changes during 1979–2010.

The average temperature of Earth maintained its warming trend in 2013, despite seasonal and regional variations that included a shrinking ice cap in the Arctic and a massively growing one in the so
