Flood basalts and mass extinctions – ancient hyperthermals as analogs for anthropogenic climate change. Oceanic Anoxic Event (OAE) and mass extinctions are considered to be hyperthermals – usually associated with flood basalt eruptions.[2] Phases of rapid global warming, known collectively as hyperthermals.[1] Flood basalts are a subset of large igneous provinces (LIPs), the terms flood basalt…
In this episode of Turbulence (Sep 15, 2017), Jake speaks with Peter Ward about the mass extinction events throughout Earth’s history, the pressing issue of climate change, the future of evolution, the future of the human race, and other topics.

Wikipedia: A flood basalt is the result of a giant volcanic eruption or series of eruptions that coats large stretches of land or the ocean floor with basalt lava. Flood basalt provinces are often called traps, which derives from the characteristic stairstep morphology of many associated landscapes. Related Greenland ice sheet collapse, triggered ancient sea…
Notice: The original video is no longer available. Published on Sep 28, 2013: “Last Hours” is the first in a series of short films that explore the perils of climate change and the solutions to avert climate disaster. Each subsequent film will highlight fact-based challenges facing the human race, and offer solutions to ameliorate these…
AGU Fall Meeting 2013: Our understanding of future Arctic change is informed by the history of past changes, which often have been both large and abrupt. The well-known ice-age events such as the Younger Dryas show how sea-ice changes can amplify forcing to produce very large responses, with wintertime sea ice especially important. These changes…
Science World Report, Aug 14, 2013: Extinctions are occurring at a phenomenal rate these days. As our climate changes and environments are altered, species are disappearing from our planet. Now, scientists are examining mass extinctions more closely. They’ve discovered how after these events in the past, species and ecosystems managed to recover in the aftermath. About…
