Roger Revelle’s 1980 Discussion of CO2 and Climate Risks

Roger Revelle, is a pioneering researcher in the study of the human influence on the atmosphere, carbon cycle and climate In 1980, then director of Scripps Institution of Oceanography, Revelle gave the talk “The Role of the Oceans in Earth’s Climate and Carbon Budget” at Lawrence Livermore National Labs. He gives a great overview…

Permafrost may release largest Mercury source on Earth

There are 32 million gallons worth of mercury, or the equivalent of 50 Olympic swimming pools, trapped in the permafrost. For context, that’s “twice as much mercury as the rest of all soils, the atmosphere, and oceans combined. And it could be released. Ambarchik: Research on permafrost at the Siberian arctic coast Permafrost…

Energy consumption Bitcoin vs Banking System

The highest estimates for Bitcoins annual terawatt hours consumption is 28.67. This means, more than 3 times more efficient than a very conservative calculation of the cost of the global banking system. Carlos Domingo: The Bitcoin vs Visa Electricity Consumption Fallacy Jonathan Koomey gets quoted in the Washington Post, and other estimates Highest…

Expert asks, can we control the climate crisis in time?

Stefan Rahmstorf speaks at the 2017 Bonn climate conference, explaining the basics of global climate change, and outlines our current emissions pathway – asking if we can control the climate crisis. The talk is titled Climate Action and Human Wellbeing at a Crossroads: Historical Transformation or Backlash?

The 936 PPM CO2 NASA Model Prediction

This NASA visualization is based on the latest IPCC report, and uses the business as usual scenario, where carbon dioxide concentrations rise to 936 parts per million—more than double today’s levels of 400 parts per million—by the year 2100. Temperature anomalies are estimated to be close to 4°C in the Arctic.


Natural Gas (Methane) likely make Climate much worse

The evidence is overwhelming that natural gas has no net climate benefit on timescales that matters to humans. A new study found that just the methane emissions leaking from New Mexico’s gas and oil industry are equivalent to the climate impact of approximately 12 coal-fired power plants. Natural Gas has Major Role in Climate…
