Summary: Over 15 years, almost 13,000 scientific papers have been published in the leading conservation science journals. Yet biodiversity remains threatened at a global scale. Researchers have now focused on this worrisome paradox by taking a deeper look at this large volume of literature. One of the major problems is that decisions are usually more […]
Summary: Scientists have analyzed significant changes in the carbon cycle over the last 540 million years, including the five mass extinction events. They have identified ‘thresholds of catastrophe’ in the carbon cycle that, if exceeded, would lead to an unstable environment, and ultimately, mass extinction… Read about this research update at sciencedaily.com: https://www.sciencedaily.com/releases/2017/09/170920182116.htm

As the Triassic Period of the Mesozoic Era began, more than 90 percent of terrestrial and marine species became extinct. Many theories have been given for why this event occurred, including ones that incorporate extensive volcanic activity, global heating or one or more terrestrial impacts… Read more here at scienceworldreport.com: How an Excess of Carbon […]
“A team of scientists, in a groundbreaking analysis of data from hundreds of sources, has concluded that humans are on the verge of causing unprecedented damage to the oceans and the animals living in them.” Report from the New York Times – nytimes.com: Ocean Life Faces Mass Extinction…
Summary: Ancient volcanic eruptions in Australia 510 million years ago significantly affected the climate, causing the first known mass extinction in the history of complex life. Scientists used radioactive dating techniques to precisely measure the age of the eruptions of the Kalkarindji volcanic province. See article below from sciencedaily.com… Australia’s deadly eruptions were reason for the […]
