Only eight EU countries to phase out coal by 2030

The EU said Tuesday that eight of its 28 member countries aim to phase out coal-powered electricity by 2030, triggering charges it is missing the mark under the Paris climate deal.

Why old-school climate denial has had its day

The Coalition has been re-elected to government, and after six years in office it has not created any effective policies for reducing greenhouse emissions. Does that mean the Australian climate change debate is stuck in 2013? ...

S.African green groups sue government over air pollution

Two South African environmental groups are suing the government over air pollution in the northeastern province of Mpumalanga, where 83 percent of the country's coal is mined, their lawyer said Monday.

Coal

Coal is a readily combustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. It is composed primarily of carbon along with variable quantities of other elements, chiefly sulfur, hydrogen, oxygen and nitrogen.

Coal was formed from layer upon layer of annual plant remains accumulating slowly that were protected from biodegradation by usually acidic covering waters that gave a natural antiseptic effect combating microorganisms and then later mud deposits protecting against oxidization in the widespread shallow seas — mainly during the Carboniferous period — thus trapping atmospheric carbon in the ground in immense peat bogs that eventually were covered over and deeply buried by sediments under which they metamorphosed into coal. In this manner, over time, the chemical and physical properties of the plant remains (believed to mainly have been fern-like species antedating more modern plant and tree species) were changed by geological action to create a solid material.

Coal, a fossil fuel, is the largest source of energy for the generation of electricity worldwide, as well as one of the largest worldwide anthropogenic sources of carbon dioxide emissions. Gross carbon dioxide emissions from coal usage are slightly more than those from petroleum and about double the amount from natural gas. Coal is extracted from the ground by mining, either underground or in open pits.
