Yikes: One Bitcoin Transaction Now Uses as Much Energy as Your House in a Week

“Bitcoin’s surge in price has sent its electricity consumption soaring.”

Well, this isn’t good news for the people speculating in the crypto-currency markets. This isn’t a problem with mining new coins in a block-chain system (which is even worse). This is per transaction. And this is happening against a background of exponential growth – which means the energy cost will rapidly increase.

Which means people trying to use the money they are mining or investing in are going to hit a computational/energy wall pretty soon, given that the growth in energy creation isn’t nearly as steep as the growth of the energy cost per transaction.

I wonder how long it will be until this collapses?

Pay attention – your life depends upon it.

Yesterday bishops and spouses from around North and Central America went to visit with the native congregations of the Diocese of Alaska. As part of our day, we joined with the people who live in this beautiful and majestic place to bless the land and thank God for the gift of it.

(Arriving at St. Matthew’s in Fairbanks)

I was part of a group that stayed in Fairbanks. We walked along the Chena River, saw the beaver dams beside water treatment plants and worshiped and ate at St. Matthews – one of the oldest congregations in this region. We heard the stories of the elders about how the community worked together to survive the winters and celebrate the everyday events of their lives: baptisms, weddings, confirmations and more. The recently retired, long serving rector addressed us all. “Fifty odd bishops” he named us. (He has no idea how accurate that is.)

(Beaver Dam)

He spoke to us on a pedestrian bridge as we pronounced the blessing along with others spread out across the state. He told us of how people in Alaska have learned to pay attention to what was happening around them. They learned to that or they died. They learned to speak of the wind and its direction, because if the direction changed, and you were out on the ice, you’d be carried out to sea – or in danger of being crushed as the ice piled up on the land. He told of how important it was to pay attention to the temperature – and whether it was rising or falling. He talked of noticing the ice as you walked – if it was suddenly thinner than thought, you would fall through and die.

Paying attention in the wilderness is life or death business.

It strikes me that paying attention to Creation in a era of climate change is life or death business whether you are in the wilderness or not. And paying attention to the spirit of the age is life or death business as we increasingly encounter voices that gain more power be creating division – rather than dying to self to draw all people toward the One on Whom We All Depend.

Jesus told us about this need. He told his disciples to be awake in the night and to watch for the coming of God – and the breaking of the dawn light. He too told us that paying attention to the signs of the time was so important that our lives depend upon it. (Mark 13:32ff or Luke 12:40ff or Luke 21:36 or…)

Maybe we should listen the wisdom of the elders of Church as they point us to the Wisdom of Only Begotten One. Our lives depend on it – in this wilderness time.

Fairbanks via Seattle

The Fall 2017 House of Bishops meeting is being held in Fairbanks Alaska this year. Held in Fairbanks is sort of a misnomer. We’re spending part of our time in Fairbanks, and the main meeting site is in Fairbanks, but Alaska being Alaska, we’ll be spending time away from the city – far away – too. Some of the bishops are going to be loaded on to mail planes I’m told, to fly out to villages along the Yukon that are only accessible by air, and will visit small Episcopal congregations to worship and talk with the communities they serve.

We’ll be talking about climate change and how it is creating pressures for the people in Alaska. We talk about the same topic in Rhode Island, and are even thinking about which church building will be imperiled over the next few decades, but what we’re facing in RI is nothing like the major dislocating changes that are coming the Artic region and the people who live around the Artic Sea.

The Episcopal Café has some pretty good background published on their site if you’re looking for more information.

I’ve never been to Alaska – and never imagined that my first visit would be as far north as Fairbanks. I admit to hoping for clear skies and an active solar magnetosphere. (I’ve never seen the Aurora Borealis.) I wish I had found space to bring my good camera with me. (I’ll try to make do with the camera in my cell phone.) Keep us all in your prayers this week as we listen and learn and pray.

I’ll post pictures as I get them – and impressions as I receive them.

Grace for Creation: free!

We have a great tradition of holding classes for parishioners in Lent, but once Easter comes, and Spring springs, we tend to focus on other things. But, what would happen if we tried an Easter class – like a Lent class, but later?

Have I got a deal for you:

In 2011, the Episcopal Church House of Bishops issued a pastoral letter on the environment. In response, a five-week study course titled A Life of Grace for the Whole World has been created. The curriculum follows the five sections of this letter.

via Curriculum – Grace for Creation

This is the result of work done by the Episcopal Church in New England, spearheaded by Bishop Tom Ely and two incredibly talented priests, Stephanie Johnson and Jerry Cappel. It’s a perfect fit for a springtime course, and it’s basically turn-key. Download it and go. The only thing we ask is that if downloadbutton.jpgyou use it, you let us know how it went. What could be easier?

Bill Nye contra climate change deniers

Bill Nye, the Science Guy, is releasing a new book on the science behind Climate Change and the implications – in the short and long term – for all us.

When asked about the myths that have come to surround the whole topic he speaks very plainly:

The biggest myth is that scientific uncertainty, plus or minus so many percent, is the same as doubt about the whole thing. And that’s wrong; that’s patently wrong. And that’s a dangerous confusion. This is one of the big reasons I wrote the book.

The full interview is here: Bill Nye demolishes climate deniers: “The single most important thing we can do now is talk about climate change.” – Salon.com

Former Presiding Bishop Katharine Jefferts Schori says something very similar in a video we and others did on the Catechism of Creation (that ought be out and available for parish and small group use any day now…)

Thorium based energy economy?

Here’s an interesting idea. Apparently there’s a company in the US that is about to release a small power generating device capable of providing up to 250 megawatts of power in a 500 pound unit small enough to fit in the engine compartment of a car.

The device uses Thorium, a relatively common rare-earth element. The US leads the world in thorium reserves.

“The key to the system developed by inventor Charles Stevens, CEO and chairman of Connecticut-based Laser Power Systems, is that when silvery metal thorium is heated by an external source, it becomes so dense its molecules give off considerable heat.

Small blocks of thorium generate heat surges that are configured as a thorium-based laser, Stevens tells Ward’s. These create steam from water within mini-turbines, generating electricity to drive a car.

[…]Because thorium is so dense, similar to uranium, it stores considerable potential energy: 1 gm of thorium equals the energy of 7,500 gallons (28,391 L) of gasoline Stevens says. So, using just 8 gm of thorium in a car should mean it would never need refueling.”

More here.

Assuming this is plausible and economically viable, this is kind of a big deal.

The power of a 747 jet at take off is about 100 megawatts. This would generate more than twice that. Imagine how much more a jet could carry without needed to lift all that fuel… Or imagine buying a car that would never need to be refueled. (A few grams of thorium would easily power it for the useable life time. 1 gram of thorium has the energy equivalent of 7500 gallons of gasoline.)

Or, think what you could do with powering houses off grid with a fuel station like this. Actually, forget houses. A small 500 lb generator could supply everything a small city needs.

The big issue with this would be managing exhaust heat. Thorium and uranium decay are the chief cause of the the planetary interior heating. It’s where the lava comes from.

The upshot is energy for all. The downside is this would accelerate heat-death due to the second law of thermodynamics.

Reevaluating some global warming claims (polar bears probably not going to drown)

There’s a group that’s been looking at driftwood dispersal as a measure of the historic extent of the ice sheets in the northern hemisphere. It’s interesting right now because there’s been a series of claims that we’re close to or have crossed the tipping point where we are about to lose all of the northern ice cap.

That would create a huge problem as the oceans suddenly receive a huge supply of cold fresh water from the melt. It’s thought that such an infusion might slow down, or even stop, the conveyor effect – which is the driver behind the Gulf Stream current. Stopping that current would have a huge climatological effect on northern Europe.

But a team, looking at the best data we’ve go right now says, maybe we should all calm down:

“Dr Funder and his team say their data shows a clear connection between temperature and the amount of sea ice. The researchers concluded that for about 3,000 years, during a period called the Holocene Climate Optimum, there was more open water and far less ice than today – probably less than 50% of the minimum Arctic sea ice recorded in 2007.

But the researcher says that even with a loss of this size, the sea ice will not reach a point of no return.

“I think we can say that with the loss of 50% of the current ice, the tipping point wasn’t reached.””

Global “cooling” due in large part to coal plant increase

Why is the Earth so different than Venus? Both planets are roughly the same size, and both exist within what is known as the “Life Zone” in the solar system. (The Life Zone is the region of solar space where it’s possible for liquid water to be found on the surface of a planet.)

I used to ask that question every semester when I got to the section on planetology in an Astronomy course, and I never had a good answer.

The best answer seems to be that life evolved on the surface of the Earth and it didn’t on the surface of Venus. Because of life, much of the carbon CO2 in the early atmosphere, which was created by volcanic outgassing on both planets and was primarily CO2 and methane, both major greenhouse gasses, was sequestered out of the atmosphere and stored in giants rafts of bacteria on the Earth’s surface. As the CO2 was scrubbed, the greenhouse effect diminished and the surface temp dropped. Eventually the temperature dropped to a point where liquid water could collect on the surface, in which even more CO2 could be dissolved, which accelerated the process.

(Key point this. For people who argue that life can not drive global warming (of which the anthropogenic idea is a part), then they have to come up with a different explanation for the primordial cooling of the Earth and otherwise explain the wildly different surface temps between the Earth and Venus.)

Venus, where we have not found life, is still so hot on the surface that the ground has the consistency of stiff oatmeal – it’s not cooled enough to lose its plasticity.

So what happens if we reload the atmosphere with CO2? Temps should rise until the extra CO2 can be absorbed in the water or sequestered by biological processes (like stored in limestone). That assumes that ocean isn’t saturated CO2 (which it appears to be) and can absorb the additional gas. (Bio processes take a very long time, and they can contribute to CO2 just as they can act to sequester it.)

So, if we’re putting more CO2 in the air (which we are) at an increasing rate (which we are), then why isn’t the temperature rising right now? That’s been the biggest criticism of anthropogenic global warming. Temps increased for a while in the early 20th cent. and then started to level off.

A group of scientists think they’ve found the answer.

“”The masking of CO2-induced global warming by short term sulphur emissions is well known – it’s believed that the flattening off of global mean temperatures in the 1950s was due to European and US coal burning, and just such a mechanism could be operating today from Chinese coal,” he told BBC News.

“Other natural fluctuations in the Sun’s output, volcanoes and water vapour have also been proposed for causing the non-warming ‘noughties’, and may have contributed to a degree.

“It needs to be emphasised that any masking is short-lived, and the increased CO2 from the same coal will remain in the atmosphere for many decades and dominate the long-term warming over the next decades.”

Since the end of the study period, in 2007, China’s coal consumption has risen again by about 30%.”

More here.

So this is basically a form of the old Nuclear Winter idea that was thought to be a consequence of an unrestrained global nuclear war (back in the days when we were worried about such things). The problem here is that there’s not enough junk being put into the atmosphere to overcome the greenhouse effect longterm. And since we’re not going to mask it, the system will very quickly and exponentially begin to be driven by the greenhouse warming.

We talk about Venus as a place of run-away greenhouse effect. If we don’t get a handle on things here on Earth, at some point, just in the way that the existence of life on the surface of Earth had the long term effect of cooling the planet, so too will life restore it to a closer resemblance to our sister planet.

Climate change God’s judgement not Man’s fault?

The BBC has a report this morning on a growing sentiment in parts of the developing world that the climate change that they are witnessing is not due to the actions of humankind. They are a result of God’s judgement upon us. And as such, there is nothing we can change that will have any effect on the situation other than pray for help.

From the end of the article:

“Climate change is a global issue transcending national boundaries, but impacting first on those who can least afford to cope with the consequences.

The ‘God not man’ cry from the lady in Kenya’s northern reaches illustrates a common problem relating to understanding the underlying causes, and underscores the incapability of people in such situations to deal with the crisis that has impacted so severely on their communities.

As Wangari Maathai, the Nobel Peace Prize winner, notes:

‘Climate change will bring massive ecological and economic challenges… therefore, alleviating dehumanising poverty will become even more difficult.'”

Read the full article here.

The point the article is trying to make, but doesn’t really in the end, is that attributing the climate changes to God leads us to think that God is going to be the one who’s going to reverse them. It’s the very definition of magical thinking and is not likely to be very effective.

It doesn’t seem all that different, to me at least, than the line of thought attributed to people like the former Secretary of the Interior, James Watt, who believed the rapture was so imminent that there was no reason for Christians to conserve natural resources. Instead, the reasoning went, profligate use of the resources was a sign of strong faith that God was coming soon and would remake the earth and effectively restore everything we had used.

Not unlike using the ever-increasing equity in our homes to pay off our ever increasing credit card debt…

The BBC article really doesn’t suggest any solutions to the problem of magical thinking among the poor in the developing world other than to “harness the power of youth”. But as the sixties remind all of us who grew up in them, that doesn’t really guarantee anything. Youth can act destructively as likely as they might act constructively. Such is the way of mankind.

Better, for Christians at least, would be to emphasize the meaning of stewardship among the Christian people in the developing world. We should be encouraging them to expect their governments to find ways to live gently in their environment, to do their collective best to steward the natural riches of the nations in which they live. I remember when I was in Swaziland, talking with local farmers who had begun to realize the toll that western style, petrochemical based agriculture was taking on their tribal lands. The old style tradition of small gardens, compost and regular crop rotation was much more effective at producing enough to eat, and was sustainable.

Of course that will require those of us who live in the developed world to put our money where our mouth is first. Otherwise why should anyone listen to us? We’d be like the Pharisees who bind others with burdens too great to bear while finding loopholes to excuse ourselves.

It will probably require us to downsize the homes we live in, move back into the cities closer to the places we work and shop, buy smaller cars, etc. In other words, live more like European society has been living for years. It’s really not an awful thing to contemplate if we put it into that context is it?

Will our actions make a difference? There’s a legitimate disagreement going on about whether the climate change we are observing is caused by human actions or not. But if not, it makes sense to act conservatively so as to try our best not hasten the rate of the change. Plus living as if it were will help us to start focusing our attention on what might be needed to survive what might come.

It’s not all that bad really. Imagine living in a small German, French or Italian city, or in one of the villages that surround them. What’s to fear in that future?

Climategate and the Irish Church scandal

Last week, while most of us here in the states were busy spending time with family and friends, the ongoing scandal of “Climategate” took a couple of new turns.

Climategate is the popular term referring to the release by a computer hacker of a large body of private emails written by climate researchers. As people have combed through the emails they’ve found a number of questionable statements regarding the data the researchers have been citing to support their contention that Earth is growing warmer.

Note that there’s a variety of terms and causes that are typically included under the popular phrase “Global Warming”. People use that term to imply that human beings, by using fossil fuels, are causing a global rise in temperatures that will have deleterious, even catastrophic effects on our climates.

But, more accurately people can speak of climate change (which means that some places are getting warmer and others are getting colder), anthropogenic change (which means human caused change), global warming in general (which means a rise in average temperatures on the surface of the earth), and rising Carbon levels (which can both be of natural cause and/or human origin) that can contribute to global warming.

How these different things lead to one another, or even interact is not well understood. It’s not even clear that there’s anything we as humans can do to change the system or that we’re driving whatever change is being observed. But all of those questions are dependent on what has, until now, been a broadly accepted set of data that show that whatever the cause or mechanism, global temperatures are getting higher.

But that data is being called into question because of some references within the emails referred to above. These references have caused broad calls that the raw data about the temperature rise be fully published. Until last week, these calls were being rejected.

That changed over the weekend:

“The U-turn by the university follows a week of controversy after the emergence of hundreds of leaked emails, ‘stolen’ by hackers and published online, triggered claims that the academics had massaged statistics.

In a statement welcomed by climate change sceptics, the university said it would make all the data accessible as soon as possible, once its Climatic Research Unit (CRU) had negotiated its release from a range of non-publication agreements.”

From here.

This is critically important, and frankly should have happened long ago. The scientific method fundamentally depends upon transparency. The worst sin a scientist can commit is to fake data. Data points need to be published, and the methods used to obtain them fully disclosed so that the data can be verified and if not, errors can be identified.

The fact that there are loud critics challenging results is no reason at all to hold back on the publication of raw data. If anything it all the more reason to be scrupulously honest. If there are errors, the opponents are going to be the most likely people to find them. And if they’re found, they can be corrected. Which will lead to better data, and better understanding of what is happening. Lather, rinse, repeat.

I can add that I believe the same thing to be true about pretty much any human endeavor, including theological thinking and church governance.

There’s been a great deal of human mischief done to people by the Church because of the sense that the institution needs to be protected from harsh questions. Take the situation in Ireland right now. A series of four archbishops have acted to cover up many many cases of sexual abuse by clergy inflicted upon children throughout that country. Their need to protect the church from “scandal” and not the children, has allowed the abusers to continue to have free access to more victims.

A transparent and public airing of the scandal from the very beginning would have been very embarrassing for the Church. But it would have saved the lives of many children. There’s no doubt what Jesus would do.
