Climate Change Elevator Pitch: Naomi Oreskes
Naomi Oreskes, author of Merchants of Doubt, Peter Sinclair talked to her in December, 2014, in San Francisco.
Siberian Arctic permafrost decay and methane escape
Widespread seafloor gas release from the seabed offshore the West Yamal Peninsula, suggests that permafrost has degraded more significantly than previously thought. Gas is released in an area of at least 7500 km2 in water depths >20 m.((Offshore permafrost decay and massive seabed methane escape in water depths >20 m at the South Kara Sea shelf | http://onlinelibrary.wiley.com/doi/10.1002/grl.50735/abstract | Alexey Portnov,…
BOOM: Oil Price Collapse and why it is Important
I recently mentioned, get out of fossil energy while you still can, when the price for crude was at $64.82. Though, today it has approached $55.84, with many oil guys loosing a fortune, oil billionaire Hamm lost half his fortune in three months. And the New York Times noted, free fall in oil price underscores shift…
The Siberian Traps and Volcanic Mass Extinction
Siberian Flood Basalts – MIT: About 252 million years ago, the largest mass extinction and the largest volcanic eruptions in Earth history occurred apparently synchronously. Massive volcanic eruptions set the stage for dinosaurs’ demise http://arstechnica.com/science/2014/12/massive-volcanic-eruptions-set-the-stage-for-dinosaurs-demise/ Bill McGuire: Modelling suggests with ice cap melt, an increase in volcanic activity https://climatestate.com/2014/10/16/methane-hydrate-destabilisation-is-clearly-a-real-worry-particularly-in-the-context-of-warming-ocean-waters-in-the-east-siberian-continental-shelf/ Siberian Traps http://en.wikipedia.org/wiki/Siberian_Traps Deccan Traps http://en.wikipedia.org/wiki/Deccan_Traps
Royal Society: An introduction to climate change in 60 seconds
Published on Dec 10, 2014: Climate science explained in 60 seconds by the Royal Society and the US National Academy of Sciences. During the last 200 years, human activities such as the burning of fossil fuels have increased concentrations of CO2 in the atmosphere by 40%. If unchecked, continuing emissions will warm up the planet…
Mythbusters tests global warming theory – does CO2 warm air?
Mythbusters build transparent boxes, filled some with carbon dioxide (CO2) and methane (CH4), then monitored temperature differences.
Natural Gas versus Coal Power Plants: Greenhouse gas warming
Ken Caldeira: We had a paper come out comparing effects of natural gas versus coal plants, aimed at understanding how much methane leakage there could be from natural gas before it caused more near-term warming than coal. The answer depends on how efficient the different power plants are, but one thing that is clear is…
Dr. Richard Alley on Undersea Methane
Interviewed in San Francisco, December, 2013. Dr. Alley worked with the National Academy of Science to produce a study of abrupt climate change impacts, including the so-called “methane bomb” – an uncontrolled release of methane from the arctic ice shelves.
What Is Biochar Gardening?
Expert tree care Tallahassee gardening services. CBS – MINNEAPOLIS (WCCO) — The mayor of Minneapolis and the chairman of the Shakopee Mdewakanton Sioux signed an agreement Tuesday that promotes the use of biochar.Jim Doten, Minneapolis’ environmental services’ supervisor, says it’s a product similar to cooking charcoal that’s used for gardening.“They really increase the soil fertility,…
