NASA Documentary: The Search For Life 🚀(2017)

On September 21, 2016, NASA scientists and stakeholders came together at the Smithsonian National Air and Space Museum for a presentation on the agency’s search for life beyond Earth. “The Search for Life” featured presentations from some of NASA’s leading scientists, including the late former astronaut, Dr. Piers Sellers. Through compelling visualizations, “The Search for…

Biogeochemical regulation: Anoxia in the Past and Present (September 2016)

September 2016: Professor Andrew Watson FRS, (University of Exeter, UK) speaks at Royal Society event Ocean ventilation and deoxygenation in a warming world. Abstract The major biogeochemical cycles which keep the present-day Earth habitable are linked by a network of feedbacks which has led to a broadly stable chemical composition of the oceans and atmosphere…

Study: Contribution of Antarctica to past and future sea-level rise (2016)

A study published in March 2016, suggests that large parts of East Antarctica’s ice sheet can collapse, can do so under Pliocene conditions. A key question has long been whether ice sheet contribution could accelerate substantially, by an order of magnitude, either in this century or subsequently. Until recently ice sheet models had problems to…

Dan Lunt: Past climates and climate sensitivity #DeepTime #Reconstruction #3DEdition

To curiosity-driven scientist Dan Lunt, understanding the past climate of our Earth (from the scorching greenhouse of the mid-Cretaceous, to the frozen wastes of the last ice age) is of fundamental interest.

Research links abrupt paleoclimatic change to possible methane hydrate destabilization

Using a core sample from the Santa Barbara Basin, UCSB researchers decipher the history of paleoclimate change with surprising results By Julie Cohen (UCSB): Global climate change isn’t new — the phenomenon has been around for millions of years. But now, a core from the ocean floor in the Santa Barbara Basin provides a remarkable…

Doubling times of 10, 20 or 40 years yield sea level rise of several meters

According to a new study, sea level rise of several meters might happen faster then previously thought. Based on data from past climate changes, when sea level rose to +5–9 m, including the occurrence of extreme storms – during a time when temperatures were less than 1 ◦C warmer than today, experts warn of similar…

A world with this much CO²: lessons from 4 million years ago

With Dr Chris Brierley, UCL Geography In Spring last year, carbon dioxide concentrations passed 400 parts per million in the atmosphere — a level not seen since the Pliocene era (3-5 million years ago), and perhaps not even then. We know that the Pliocene was a warm world without glacial cycles, and that the climate…

Abrupt Climate Change explained by Jim White, 12 Minutes excerpt (@AGU 2014)

Climate is changing as humans put more and more greenhouse gases into the atmosphere. With CO2 levels today around 400ppm, we are clearly committed to far more climate change, both in the near term, and well beyond our children’s future. A key question is how that change will occur. Abrupt climate changes are those that…

Bill McGuire: Modelling suggests with ice cap melt, an increase in volcanic activity

ClimateState interviewed Bill McGuire, Emeritus Professor of Earth Sciences at the University College London, one of Britain’s leading volcanologists and contributing author to the 2011 IPCC report. He called for an early tsunami warning system (2004, The Guardian) and warned in his book The Waking Giant, of the Earth response (more earthquakes, tsunamis and landslides)…

Experts: Arctic craters could be ‘Visible Effect’ of Global Warming

The preliminary results from scientists studying the mysterious holes (craters), that began emerging in recent times in Siberia, indicate that climate change may be a cause. The Russian crater research team led by Alexei Plekhanov of the Scientific Centre of Arctic Studies, explained a possible mechanism, in a Nature interview. The past two summers were…

Novel climate proxy reveals CO2 content of Earth’s atmosphere, of the past 400 million years

The study New constraints on atmospheric CO2 concentration for the Phanerozoic (DOI: 10.1002/2014GL060457), by Peter J. Franks, Dana L. Royer, David J. Beerling , Peter K. Van de Water, David J. Cantrill, Margaret M. Barbour, and Joseph A. Berry, estimates CO2 in Earth history based on a new climate proxy. Estimates are in particular based…

Everything you need to know about Mass Extinction, Sea Level Rise and Amplification

Professor Peter Ward (Professor, Sprigg Institute of Geobiology, The University of Adelaide) explains the interconnections of rising carbon dioxide levels and flood basalt, and how it leads to anoxic oceans (with Hydrogen sulfide). Ward explains how today’s CO2 levels will result in sea level rise with disrupting implications for crops and how deglaciation will ultimately…
