Sea ice and carbon dioxide by Hambler, C, Henderson, PA

Temperature, carbon dioxide and methane by Hambler, C, Henderson, PA

“…1) Globally-representative monthly rates of change of atmospheric carbon dioxide and methane are compared with global rates of change of sea ice and with Arctic and Antarctic air temperatures. 2) Carbon dioxide is very strongly correlated with sea ice dynamics, with the carbon dioxide rate at Mauna Loa lagging sea ice extent rate by 7 months. 3) Methane is very strongly correlated with sea ice dynamics, with the global (and Mauna Loa) methane rate lagging sea ice extent rate by 5 months. 4) Sea ice melt rate peaks in very tight synchrony with temperature in each Hemisphere. 5) The very high synchrony of the two gases is most parsimoniously explained by a common causality acting in both Hemispheres. 6) Results are consistent with a proposed role of a high-latitude temperature-dependent abiotic variable such as sea ice in the annual cycles of carbon dioxide and methane. 7) If sea ice does not drive the net flux of these gases, it is a highly precise proxy for whatever does. 8) Potential mechanisms should be investigated urgently.…”

Global decarbonisation patterns – total and transport CO2 intensity by Tapio, P, Finel, N, Banister, D, Luukkanen, J, Vehmas, J, Willamo, R

Sea ice and argon by Hambler, C

“…1) Atmospheric argon on Earth and Mars cycles on a seasonal basis and abiotic factors will be particularly important drivers of this noble gas. 2) It is predicted and confirmed that there is similarity in the seasonality of sea ice and argon, with atmospheric argon in a Hemisphere often increasing fastest when sea ice in that Hemisphere is declining fastest. 3) There is some visual similarity between the detailed phenology of Greenland Sea ice extent and argon in some Northern Hemisphere sites, but formal analysis is required. 4) If causal, the mechanism is unclear but could involve argon bubble formation during freezing and bubble release in the spring melt. 5) Other variables with very similar phenology to sea ice, including high-latitude sea temperatures, should be investigated as potential drivers. 6) Cycling of argon by sea ice would strengthen the argument that seasonal cycling of carbon dioxide is in part driven abiotically.…”

Monopolistic sequestration of European carbon emissions by Jaakkola, N

“…These investments include pipeline networks for transporting carbon dioxide (CO2) from industrial sites ('sources') to the storage sites ('sinks'). …”

Why do CO2 emissions differ in China, Japan and Korea? by Chung, H

“…Scientific evidence suggests that a continued increase in the atmospheric concentration of carbon dioxide (CO,) and other greenhouse gases resultant from human activities will lead to global climatic change with a potentially catastrophic impact. …”

Exploring the Carbon Kuznets hypothesis by Müller-Fürstenberger, G, Wagner, M, Müller, B

“…The Carbon Kuznets hypothesis conjectures an inverse U–shape relation between GDP and carbon dioxide emissions. We investigate a number of empirical problems with this hypothesis by way of both econometric analysis and CGE modelling. …”

The modelling of anthropogenic methane emissions : methodology and estimates by Müller, B, Bartsch, U

“…Six gases were singled out, of which carbon dioxide (CO4 and methane (CH4) are the most important, accounting for about 95 per cent of global anthropogenic GHG emissions. …”

Nuclear power in China: its role in national energy policy by Andrews-Speed, P

“…The government’s policy objectives driving this programme are fourfold: enhancing security of energy supply, reducing carbon dioxide emissions, promoting advanced industrial and technological development, and boosting technology exports. …”

Investment in electricity generation under emissions price uncertainty : the plant-type decision by Tuthill, L

“…Two models are presented in which the policy variable, the carbon dioxide (CO2) price, is assumed to evolve according to two different stochastic processes, each representing a different degree of possible future government intervention. …”

Greenhouse gas network design using backward Lagrangian particle dispersion modelling - Part 1: Methodology and Australian test case by Ziehn, T, Nickless, A, Rayner, P, Law, R, Roff, G, Fraser, P

“…This paper describes the generation of optimal atmospheric measurement networks for determining carbon dioxide fluxes over Australia using inverse methods. …”

Cumulative Carbon Emissions and Climate Change: Has the Economics of Climate Policies Lost Contact with the Physics? by Rhys, J

“…Carbon dioxide (CO2) emissions are essentially cumulative in character; but much of the economic analysis and policy making in relation to the mitigation of CO2 emissions fails to reflect fully this fundamental feature of any analysis of the impact of emissions on climate. …”
