Did volcanoes kill the dinosaurs? New evidence points to ‘maybe.’

(Princeton University) Princeton geoscientists Blair Schoene and Gerta Keller led an international team of researchers who have assembled the first high-resolution timeline for the massive eruptions in India’s Deccan Traps, determining that the largest eruption pulse occurred less than 100,000 years before the mass extinction that killed the (non-avian) dinosaurs.

Do volcanoes or an asteroid deserve blame for dinosaur extinction?

Scientists have obtained more precise dates for the Deccan Traps volcanic lava flows, linking peak activity more closely to the asteroid or comet impact 66 million years ago and the coincident mass extinction. But if greenhouse gases emitted before the impact created a hothouse climate that set life up for a fall when the impact cooled the planet, those gases did not coincide with the largest lava flows from the Deccan Traps.

Coastal waters are unexpected hotspots for nitrogen fixation

Nitrogen fixation is surprisingly high in the ocean’s coastal waters and may play a larger role than expected in carbon dioxide uptake, a new study shows. The findings — based on thousands of samples collected in the western North Atlantic — upend prevailing theories about where and when nitrogen fixation occurs, and underscore the need for scientists to revisit the global distribution of marine nitrogen fixation and reevaluate its role in the coastal carbon cycle.

Expanding the use of silicon in batteries, by preventing electrodes from expanding

(Drexel University) Silicon anodes are generally viewed as the next development in lithium-ion battery technology. Silicon’s ability to absorb more charge translates to longer battery life and smaller batteries, if researchers can check the physical expansion of the silicon that comes with charging. Research from Drexel University and the Trinity College in Ireland, suggests that adding MXene ink to the silicon electrode-making process would do just that.

Environmental activists to take legal action against US Steel for polluting

Environmentalists are taking legal action against United States Steel Company (U.S. Steel) because of pollution in Pittsburg’s Mon Valley. The Clean Air Council and PennEnvironment are suing the steel manufacturer for violating the Clean Air Act after a fire broke out at a facility in Clairton, Pennsylvania. “We cannot expect families to sustain this kind of health burden and trauma, and we cannot expect kids to learn, grow and flourish when they are confined to their homes, unable to breathe,”…

Arctic Sea Ice Continues To Grow

Last year had the highest June Arctic sea ice volume since 2006, and this year is well ahead of last year. Spreadsheet     Data Most of the Arctic is covered with ice more than two meters thick. CICE_combine_thick_SM_EN_20190215.png (758×631) Arctic…

Extreme Wildfire Fraud In The National Climate Assessment

Yesterday I showed how the National Climate Assessment is committing blatant fraud about heat waves by hiding the data that shows their claims are inverted from reality. Extreme Fraud In The National Climate Assessment | The Deplorable Climate Science Blog…

Massive Bolivian earthquake reveals mountains 660 kilometers below our feet

Geophysicists used data from an enormous earthquake in Bolivia to find mountains at the base of the mantle’s transition zone, located 660 kilometers below our feet. Their statistical model didn’t allow for precise height measurements, but these mountains may be bigger than anything on the surface of the Earth. The researchers also examined the top of the transition zone (410 km down) and did not find similar roughness.
