In this paper, a two year experiment with six rates (0, 75, 150 , 225 , 300 , 375 N/ha) of nitrogen fertilizer application was designed to examine GHG emissions by measuring carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) flux and their cumulative global warming potential (GWP) from paddy fields in Hangzhou, Zhejiang in 2013 and 2014.
The effects of the warm phase of the PDO and the current El Niño may be cumulative in terms of warming the planet.
Impacts for the indicators global warming potential, cumulative energy demand fossil, eutrophication potential, and human health carcinogenic are also lower than in the base case, albeit only by a small percentage.
The other differences between the two versions of the pumped hydropower station are hardly visible for the indicators global warming potential, cumulative energy demand metals, eutrophication potential, and human health carcinogenic, as impacts are dominated by the impacts of the operational stage, which remain the same as in the base case.
Under the cumulative weight of acidification, warming, habitat destruction, coastal pollution and overfishing, the ocean environment may soon become fit only for jellyfish.
The indicators global warming potential and cumulative energy demand were selected to reflect this.
But we're still the largest source of warming in terms of cumulative emissions, and on a per-capita basis Americans produce more CO2 than just about anyone except the Qataris.
The primary response was the change observed between 2003 and 2004, while the secondary response was between 2005 and 2006 and the cumulative response was the observed change between the initiation of the warming experiment in 2003 and 2006.
Burning fossil fuels for energy over the past two centuries has now warmed the planet about 1 degree Celsius (about 1.5F), with at least another 0.5C of warming likely as global temperatures continue to rise in response to cumulative historical emissions.
The cumulative effect of the carbon dioxide and other heat-trapping gases released since the dawn of the Industrial Revolution are likely to add another half a degree Celsius (0.9F) to warming that's already occurred, "So what we are seeing is the veritable tip of the iceberg," he said.
