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.

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?

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. https://svs.gsfc.nasa.gov/cgi-bin/details.cgi?aid=11453

We hear all the time that we need to stop the planet from warming an additional two degrees Celsius above pre-industrial levels. Why is that specific number so important though? And what happens if we exceed that limit? William Brangham offers some background on that climate science target.
Leaders Event – Statements by Heads of State and Government, at the 2015 United Nations Climate Change Conference COP21. In light of the 14 warmest years on record since 2000, Obama urges bold actions. Highlighting coastal erosion, lose of farm land, flooding, or ice lose he points out that we are the first generation which…
A Breathing Planet, Off Balance NASA: Earth’s land and ocean currently absorb about half of all carbon dioxide emissions from the burning of fossil fuels, but it’s uncertain whether the planet can keep this up in the future. NASA’s Earth science program works to improve our understanding of how carbon absorption and emission processes work…
Think of climate change as a cancer. Your doctor told you that he spotted what appears to be likely a melanoma skin cancer, but he is not 100% sure. Do you wait till the signs become more apparent? The cancer might spread in your body, by that diminishing the chance for survival, or do you ask the…
