A new IEA report: Following two years of small declines, energy-related CO2 emissions rose to a record high in 2017. The increase in carbon emissions “was the result of robust global economic growth of 3.7%, lower fossil fuel prices and weaker energy efficiency efforts.” Fast-growing Asian economies accounted for two-thirds of the increase.
Summary of an interview with Paul Ehrlich. Professor Ehrlich became famous fifty years ago when his book about the perils of overpopulation was published. The famine he predicted then was avoided by the green revolution but other problems having serious consequences have accelerated. He now thinks a collapse of civilization within decades is a near certainty, putting much of the blame on things like overconsumption and increases in toxic pollution—but surprisingly little on climate change.
A limited nuclear exchange today, on any part of the Earth, would cause severe cooling conditions globally that last for many years. That is the current prevailing view from scientists, but not well-publicized. “And it’s not just one computer model simulation that is projecting a sharp global cool down and potential famine from a nuclear conflict….This is something that has been confirmed now in multiple climate models.”
Report based on a recent study of wildfire projections for North America. “By 2039, the researchers estimate there will be 50 fewer days of snowpack in much of the West and a four-degree Fahrenheit increase in average temperature. Both trends will create longer fire seasons that burn much more land.” In the eleven states that are most affected the average annual area burned would then be likely to increase 500%. This work was based on comprehensive studies of events over the past three decades, the speeding change of which has amazed those doing the research.
A better way to install solar panels at ground level. The interesting low-tech idea is simple and practical, and the savings involved are large enough to make a real difference in the total cost of producing solar electricity by this type of setup, which is commonly employed on large acreages all over the world. It should give the industry a competitive boost.
