Electric vehicles – It's not just about the car - "One of the key characteristics of complex systems, such as the world's energy and transport sectors, is that when they change it tends not to be a linear process. They flip from one state to another in a way strongly analogous to a phase change in material science... A second important characteristic of this type of economic phase change is that when one major sector flips, the results rip through the whole economy and can have impacts on the societal scale."

Logic hacking - "Writing shorter and shorter computer programs for which it's unknowable whether these programs run forever, or stop... the winner of the Busy Beaver Game for N-state Turing machines becomes unknowable using ordinary math - somewhere between N = 5 and N = 1919." [more inside]
Alaska is Having Its Hottest Year Since Records Began - "After a spring that was a full ten degrees hotter than normal, the northern state is on track for the most sweltering year on record." (via) [more inside]
The case for optimism on climate change - "I'll finish with this story. When I was 13 years old, I heard that proposal by President Kennedy to land a person on the Moon and bring him back safely in 10 years. And I heard adults of that day and time say, 'That's reckless, expensive, may well fail.' But eight years and two months later, in the moment that Neil Armstrong set foot on the Moon, there was great cheer that went up in NASA's mission control in Houston. Here's a little-known fact about that: the average age of the systems engineers, the controllers in the room that day, was 26, which means, among other things, their age, when they heard that challenge, was 18."

The world's coral is suddenly and rapidly starting to die - "This is only the third time we've seen what we would refer to as a global bleaching event. [The prior events] were in 1998 and 2010, and those were pretty much one year events. We're looking at a similar spatial scale of bleaching across the globe, but spanning across at least 2 years. So that means a lot of these corals are being put under really prolonged stress, or are being hit 2 years in a row." Can 'manually breeding supercorals capable of living in increasingly inhospitable waters' help in time? (via/via)
Breaking the Tragedy of the Horizon – climate change and financial stability: Bank of England Governor Mark Carney warns investors face 'huge' climate change losses - "The Financial Stability Board, an international body monitoring the global financial system that Mr Carney chairs, may recommend G20 countries make it easier for investors to compare the 'carbon intensity' of different assets."

Tesla Powerwall Battery Economics: Almost There - "Elon Musk announced Tesla's home / business battery today. [video] tl;dr: It'll get enthusiastic early adopters to buy. The economics are almost there to make it cost effective for a wide market... That said, for large scale grid deployment (outside of the home), it still looks like flow batteries and advanced compressed air are likely to be far cheaper in the long run." [more inside]
All of California remains in drought with over 80% in worst categories of 'extreme' or 'exceptional' drought. Reservoir levels are 50% below average. (previously) [more inside]
The Economic Risks of Climate Change in the United States (PDF); prospectus (PDF); press coverage (YT) - "The signature effects of human-induced climate change—rising seas, increased damage from storm surge, more frequent bouts of extreme heat—all have specific, measurable impacts on our nation's current assets and ongoing economic activity. [The report] uses a standard risk-assessment approach to determine the range of potential consequences for each region of the U.S.—as well as for selected sectors of the economy—if we continue on our current path..."

UN Climate Report: We Must Focus On 'Decarbonization', and It Won't Wreck the Economy - "The basic message is simple: We share a planet. Let's start acting like it." [more inside]
With the climate bill dead and blame portioned, Ezra Klein asks what happens when congress fails? He concludes that "regulations to reduce carbon emissions are alive and well. The Environmental Protection Agency can attack carbon as a pollutant, and the Obama administration's announcement that efforts to hamstring the EPA will be vetoed suggests that they mean to do exactly that."

Talking About Energy at TED "Bill Gates unveils his vision for the world's energy future, describing the need for 'miracles' to avoid planetary catastrophe and explaining why he's backing a dramatically different type of nuclear reactor. The necessary goal? Zero carbon emissions globally by 2050." Others, however, reckon no breakthroughs are needed.
