Carbon taxes and emission trading systems are the most cost-effective means of reducing CO2 emissions, and should be at the centre of government efforts to tackle climate change,according to a new OECD study.

The solid-state structures of two cobalt–pyridine–sulfate compounds, namely catena-poly[[tetra­kis­(pyridine-κN)cobalt(II)]-μ-sulfato-κ2O:O'], [Co(SO4)(C5H5N)4]n, (1), and catena-poly[[tetra­kis­(pyridine-κN)cobalt(II)]-μ-sulfato-κ3O:O',O''-[bis­(pyridine-κN)cobalt(II)]-μ-sulfato-κ3O,O':O'']n, [Co2(SO4)2(C5H5N)6]n, (2), are reported. Compound (1) displays a polymeric structure, with infinite chains of CoII cations adopting octa­hedral N4O2 coordination environments that involve four pyridine ligands and two bridging sulfate ions. Compound (2) is also polymeric with infinite chains of CoII cations. The first Co center has an octa­hedral N4O2 coordination environment that involves four pyridine ligands and two bridging sulfate ligands. The second Co center has an octa­hedral N2O4 coordination environment that involves two pyridine ligands and two bridging sulfate ions that chelate the Co atom. The structure of (2) was refined as a two-component inversion twin.

A series of Co2−xRuxMnSi (x = 0, 0.25, 0.5, 0.75, 1) Heusler compounds were successfully synthesized. The heat-treatment conditions were crucial to make the materials form a single phase with a Heusler structure. With increasing Ru content, the half-metallic gap, lattice parameters and magnetization are continuously adjustable in a wide range. The Co2−xRuxMnSi (x = 0, 0.25) compounds are rigorous half-metals and show a T3 dependence of resistance at low temperature. The Co2−xRuxMnSi (x = 0.5, 0.75, 1) Heusler compounds are the nearly half-metallic materials and show a semiconductive dependence of resistance at low temperature. The experimental magnetization is consistent with that in theory and follows the Slater–Pauling rule. The Curie temperature is higher than 750 K for all Co2−xRuxMnSi Heusler compounds.

The last time Earth experienced both ice sheets and carbon dioxide levels within the range predicted for this century was a period of major sea […]

Two grass species that had been relatively rare in the plots, Spartina patens and Distichlis spicata, began to respond vigorously to the excess nitrogen. Eventually the grasses became much more abundant. Nitrogen ultimately changed the composition of the ecosystem as well as its capacity to store carbon.

A new study by European researchers highlights the important contribution of greenhouse gases (GHGs) other than carbon dioxide to climate change and suggests policy measures to help reduce their impact. The study provides improved estimates of the current GHG balance of Europe, taking nitrous oxide and methane into account.

One method that has been proposed for removing carbon dioxide (CO2) from the atmosphere is to ‘fertilise’ the ocean to encourage phytoplankton (algae) blooms. A recent study has outlined the environmental, legal and social implications of large-scale fertilisation of the sea with urea in the Sulu Sea off the coast of the Philippines.

A recent study has examined the implications of CO2 leaking from storage sites under a variety of scenarios over 100,000 years. The findings suggest that ocean storage of CO2 (prohibited in the EU) would lead to long-term warming of the atmosphere, higher sea levels and acidification and dead zones in the ocean. In contrast, geological storage with low-leakage rates (1 per cent per 1000 years) would lead to conditions similar to a low-emissions future. This implies that

Technological advances in European cement production could reduce energy consumption by up to 10% and CO2 emissions by 4%, according to a new analysis. The research suggests that initial costs of some of the pending technological improvements could be recouped in as little as a year.

Rising levels of atmospheric carbon dioxide (CO2) is likely to cause some soils to release large quantities of two potent greenhouse gases (GHGs), nitrous oxide and methane, according to a recent analysis. The results suggest that the contribution of soils and terrestrial ecosystems to slow climate change has been overestimated.

The world’s ocean ecosystems will suffer warming, increased acidity, low oxygen and reduced primary food supply as a result of rising CO2 and this is likely to have dramatic environmental and social impacts, a new study concludes. It predicts that the most vulnerable low-income countries, where 870 million people are dependent on marine ecosystems, would be affected if CO2 emissions are not tackled.

Deep-water fish living along the Irish-UK continental slope remove more than a million tonnes of CO2 from the atmosphere each year, according to a recent study. Continental slope ecosystems play an important role in carbon sequestration, which should be considered before exploiting deep-water resources, say the researchers.
