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…

The Stunning Amount of CO2 Emissions [visualized]

Together with the Potsdam Institute for Climate Impact Research (PIK), the Urban Complexity Lab of the University of Applied Sciences Potsdam (FHP) developed an animated short movie that visualizes the carbon dioxide (CO2) emissions of the past – and the possible future. A Brief History of CO2 Emissions Release via Potsdam Institute —– Credits:…

Like Champagne opened, methane explosions resulted in Ocean craters

Like ‘champagne bottles being opened’: Scientists document an ancient Arctic methane explosion What could possibly go wrong, ignoring climate change, the warnings or clues from what science tells us, even if we were just creating a better world with clean energy, and millions of new jobs? One thing which could go very wrong, are based…
