Burning coal may have caused Earth’s worst mass extinction | Dana Nuccitelli

New geological research from Utah suggests the end-Permian extinction was mainly caused by burning coal, ignited by magma

Earth has so far gone through five mass extinction events – scientists are worried we’re on course to trigger a sixth – and the deadliest one happened 252 million years ago at the end of the Permian geologic period. In this event, coined “the Great Dying,” over 90% of marine species and 70% of terrestrial vertebrate species went extinct. It took about 10 million years for life on Earth to recover from this catastrophic event.

Scientists have proposed a number of possible culprits responsible for this mass extinction, including an asteroid impact, mercury poisoning, a collapse of the ozone layer, and acid rain. Heavy volcanic activity in Siberia was suspected to play a key role in the end-Permian event.

How America's clean coal dream unravelled

Exclusive: Kemper power plant promised to be a world leader in ‘clean coal’ technology but Guardian reporting found evidence top executives knew of construction problems and design flaws years before the scheme collapsed

High above the red dirt and evergreen trees of Kemper County, Mississippi, gleams a 15-story monolith of pipes surrounded by a town-sized array of steel towers and white buildings. The hi-tech industrial site juts out of the surrounding forest, its sharp silhouette out of place amid the gray crumbling roads, catfish stands and trailer homes of nearby De Kalb, population: 1,164.

The $7.5bn Kemper power plant once drew officials from as far as Saudi Arabia, Japan and Norway to marvel at a 21st-century power project so technologically complex its builder compared it to the moonshot of the 1960s. It’s promise? Energy from “clean coal”.

Energy agency rejects Trump plan to prop up coal and nuclear power plants

The unexpected decision by the Republican-controlled body is a blow to the president’s high-profile mission to revive the struggling US coal industry

An independent energy agency on Monday rejected a Trump administration plan to bolster coal-fired and nuclear power plants with subsidies, dealing a blow to the president’s high-profile mission to revive the struggling coal industry.

The decision by the Republican-controlled Federal Energy Regulatory Commission (FERC) was unexpected and comes amid repeated promises by Trump to rejuvenate coal as the nation’s top power source. The industry has been besieged by multiple bankruptcies and a steady loss of market share as natural gas and renewable energy have flourished.
