What future do we want?  +John Baez presents the issue very well:  We want energy - massive amounts of it - but our systems don't currently incorporate associated future costs.  Asking all of us to forgo immediate benefits to address a clearly foreseeable future remains difficult.  How will we respond?  It will be interesting to see what leaders, industries, countries, and policies will help us maintain our progress and growth - while addressing one of the most important issues of our time. 

"There is no political or economic system anywhere in the world currently that can persuade an energy company to leave a valuable fossil fuel resource untapped. There is no government in the world that has demonstrated the ability to forgo the economic wealth from natural resource extraction, for the good of the planet as a whole. We’re lacking both the political will and the political institutions to achieve this. Finding a way to achieve this presents us with a challenge far bigger than we ever imagined.

For a good discussion on renewables, distributed energy, land utilization, urbanization, materials, economics, sustainability, energy independence, and quality of life, see also discussions on +Mark Bruce's energy graph:

I really enjoy posting fun stuff here.  But this is serious.

Steve Easterbrook just finished writing a series of important posts on Azimuth, summarizing part of the IPCC report on climate change.  Here's a short version of his last post.  Pay attention!


To stay below 2°C of warming, most fossil fuels must stay buried in the ground.

Perhaps the most profound advance since the previous IPCC report is a characterization of our global carbon budget. This is based on a finding that has emerged strongly from a number of studies in the last few years: the expected temperature change has a simple linear relationship with cumulative CO2 emissions since the beginning of the industrial era.

The chart is hard to follow, but the main idea is this: whatever we do, the results tend to lie on a straight line on this graph. You do get a slightly different slope in one case, “1% percent CO2 increase per year", where only CO2 rises - and much more slowly than it has over the last few decades.  But all the more realistic scenarios lie in the orange band, and all have about the same slope.

This is a useful insight, because it means that for any target ceiling for temperature rise - like the UN’s commitment to not allow warming to rise more than 2°C above pre-industrial levels - we can easily estimate the total amount of carbon we can spew into the atmosphere:

• To give us a one third (33%) chance of staying below 2°C of warming over pre-industrial levels, we cannot ever emit more than 880 gigatonnes of carbon.

• To give us a 50% chance, we cannot ever emit more than 840 gigatonnes of carbon.

• To give us a 66% chance, we cannot ever emit more than 800 gigatonnes of carbon.

Since the beginning of industrialization, we have already emitted a little more than 500 gigatonnes. So, our remaining budget is somewhere between 300 and 400 gigatonnes of carbon.

Existing known fossil fuel reserves are enough to release at least 1000 gigatonnes. New discoveries and unconventional sources will likely more than double this.

That leads to one conclusion:

Most of our remaining carbon reserves must never reach the atmosphere.

We’ve never done that before. There is no political or economic system anywhere in the world currently that can persuade an energy company to leave a valuable fossil fuel resource untapped. There is no government in the world that has demonstrated the ability to forgo the economic wealth from natural resource extraction, for the good of the planet as a whole. We’re lacking both the political will and the political institutions to achieve this. Finding a way to achieve this presents us with a challenge far bigger than we ever imagined.


Red Steve's whole series of posts starting here:

Each post summarizes a key finding of the IPCC Working Group 1 report on climate change, released last year.  These findings are:

1. The warming is unequivocal.

2. Humans caused the majority of it.

3. The warming is largely irreversible.

4. Most of the heat is going into the oceans.

5. Current rates of ocean acidification are unprecedented.

6. We have to choose which future we want very soon.

7.  To stay below 2°C of warming, the world must become carbon negative.

8.  To stay below 2°C of warming, most fossil fuels must stay buried in the ground.

Partly it's our poor time/future skills.  A research claims that on average we have as much empathy for our selves 30 years into the future as for a total stranger with no connection to us now.  That's part of it, then yet another part comes in two points.  We all hope someone else will eat the pain.  It's interesting that people will even write a check to Green Peace right before they hop on a Jet plane, travel to some coast, jump on a cruise ship, motor around a jungle in a Humvee. We can complain about Carbon emissions while living an extremely high carbon lifestyle.  The other part of it is no one wants to be first, very few people will seriously alter their lifestyle as long as they see other refusing to do so.  Finally we don't have a system for deciding & enforcing action on a world wide scale because those who have it all want to arbitrage their advantage.

I made the following comment, another wording of a common theme of mine, in +Yonatan Zunger 's recient post on the Bundy ranch & special pleadings. Beyond special pleadings, the rich & corporations can make their home in many domiciles at once, so they can pick where to prosecute their case with laws & the moral force of power holders favouring them. Before I paste it, I just want to point to a new example here of this sort of arbitrage..


State rights, even the idea of the nation state, are founded on the idea that pretty much anything I or I and my clique do is my/our business alone. The development of the science of ecology has pretty much laid that concept in it's grave. Even the existence of the poorest person living the most low carbon density life possible in the most remote desert has an impact on me & you, and naturally we, pounding away on our keyboards, are having a far heavier impact on them and the ecology they must survive in.

The scoundrels have long ago learned how to play (both little state ala USA and big) State against State, and to use boundaries to escape the law & their obligations. (sic Google & the Irish / Dutch Sandwich).  The FBI isn't enough and the UN is mostly the un, as in unwilling, unable and unmanageable. 

How will we live in this new world? Not where borders no longer exist, but where they have become, ever increasingly, the impediment to safety of our health and wealth? This is going to be one of our real challenges in the future!


I'm not convinced even "good"  guys like Google are about to give up their tax loop holes in order to save the poor & many more who will soon join the ranks of poor from a horrid short life & frequent random death. That would be like asking most Americans to give up their car.  Anyone seen the leading topics in Explore on G+? heavy with gas sucking monster cars.

Earth-size and habitable-zone. :) A good candidate for liquid water and rocky terrain.  We don't know yet what the composition is - but we've seen that combination before - and it's given rise to some of the most complex, beautiful, insightful, and curious parts of the known Universe. 

NASA's Kepler Mission Discovers First Earth-Size Planet In The 'Habitable Zone' of Another Star!
April 17, 2014: This artist's concept depicts Kepler-186f, the first validated Earth-size planet to orbit a distant star in the habitable zone. Using NASA's Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the "habitable zone"—the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun.

While planets have previously been found in the habitable zone, they are all at least 40 percent larger in size than Earth and understanding their makeup is challenging. Kepler-186f is more reminiscent of Earth.
"The discovery of Kepler-186f is a significant step toward finding worlds like our planet Earth," said Paul Hertz, NASA's Astrophysics Division director at the agency's headquarters in Washington. "Future NASA missions, like the Transiting Exoplanet Survey Satellite and the James Webb Space Telescope, will discover the nearest rocky exoplanets and determine their composition and atmospheric conditions, continuing humankind's quest to find truly Earth-like worlds."

Although the size of Kepler-186f is known, its mass and composition are not. Previous research, however, suggests that a planet the size of Kepler-186f is likely to be rocky.

"We know of just one planet where life exists -- Earth. When we search for life outside our solar system we focus on finding planets with characteristics that mimic that of Earth," said Elisa Quintana, research scientist at the SETI Institute at NASA's Ames Research Center in Moffett Field, Calif., and lead author of the paper published today in the journal Science. "Finding a habitable zone planet comparable to Earth in size is a major step forward."

Kepler-186f resides in the Kepler-186 system, about 500 light-years from Earth in the constellation Cygnus. The system is also home to four companion planets, which orbit a star half the size and mass of our sun. The star is classified as an M dwarf, or red dwarf, a class of stars that makes up 70 percent of the stars in the Milky Way galaxy.
"M dwarfs are the most numerous stars," said Quintana. "The first signs of other life in the galaxy may well come from planets orbiting an M dwarf."

Kepler-186f orbits its star once every 130-days and receives one-third the energy from its star that Earth gets from the sun, placing it nearer the outer edge of the habitable zone. On the surface of Kepler-186f, the brightness of its star at high noon is only as bright as our sun appears to us about an hour before sunset.

"Being in the habitable zone does not mean we know this planet is habitable. The temperature on the planet is strongly dependent on what kind of atmosphere the planet has," said Thomas Barclay, research scientist at the Bay Area Environmental Research Institute at Ames, and co-author of the paper. "Kepler-186f can be thought of as an Earth-cousin rather than an Earth-twin. It has many properties that resemble Earth."

The four companion planets, Kepler-186b, Kepler-186c, Kepler-186d, and Kepler-186e, whiz around their sun every four, seven, 13, and 22 days, respectively, making them too hot for life as we know it. These four inner planets all measure less than 1.5 times the size of Earth.
The next steps in the search for distant life include looking for true Earth-twins -- Earth-size planets orbiting within the habitable zone of a sun-like star -- and measuring the their chemical compositions. The Kepler Space Telescope, which simultaneously and continuously measured the brightness of more than 150,000 stars, is NASA's first mission capable of detecting Earth-size planets around stars like our sun.

Ames is responsible for Kepler's ground system development, mission operations, and science data analysis. NASA's Jet Propulsion Laboratory in Pasadena, Calif., managed Kepler mission development. Ball Aerospace & Technologies Corp. in Boulder, Colo., developed the Kepler flight system and supports mission operations with the Laboratory for Atmospheric and Space Physics at the University of Colorado in Boulder. The Space Telescope Science Institute in Baltimore archives, hosts and distributes Kepler science data. Kepler is NASA's 10th Discovery Mission and was funded by the agency's Science Mission Directorate.

The SETI Institute is a private, nonprofit organization dedicated to scientific research, education and public outreach.  The mission of the SETI Institute is to explore, understand and explain the origin, nature and prevalence of life in the universe.

He calls it a "very sexy curve on a graph" and it will be a game changer.  Highly recommended article on the economics of energy from +Mark Bruce and +David Fuchs

When we think of the huge role our concentrated energy sources play in politics, war, and the economy, it's amazing. Adequate levels of distributed energy really will change everything.

Consider it a freedom to choose your energy provider as they become comparibly closer to meet your energy needs - storage being the key.
The cartels will back off production and maintain prices they want/need just as they do now. Even if our transport went to alternative energies the oil is still needed for the bitumen on the road to the lubricants in the machines so yes you're right. We will need oil for a long time to come.

I understand the argument that from a physics/mathematical perspective Now is just a arbitrarily chosen point on a timeline, not any different than any other Nows. The question why "Now" is special it that it isn't.

This may be true in a mathematical sense, yet from a perspective of our consciousness "Now" is quite unique. Dismissing it as non-special based on math seems to me to implie an asumption that math is more fundamental than consciousness. To me this is an assumtion that we are not capable of verifying, and as long as we do not understand what consciousness really is, the jury is still debating.
