Climate change, what can I do?

I was prompted to think about some new ideas

I went to a meeting at the Golden Cross in Cirencester a few days ago. We enjoyed a great presentation from Vijay Shah who spoke about his experiences in Arctic regions where climate change has been particularly severe. He also outlined other aspects of climate change including its causes and actions we might take to limit it and the damage it’s doing. Vijay pointed out that there are individual actions we can take in terms of our diet, modes of transport and so forth, and there are industrial and government actions that can be taken too. In the excellent discussion afterwards some of these individual and local matters were raised from the floor.

It was good to talk with others at the meeting, I was surprised by the wide variety of ages, professions, and opinions represented. And I was prompted to think about some new ideas that the talk sparked in my own thinking as I listened, chatted, and again as I walked home afterwards.

Some are original, others are already being widely discussed, some were mentioned at the meeting, but I present them here in the hope they will encourage others to think creatively about what is possible. Here are some of those ideas:

Streetlights – LED streetlights are becoming common in towns and villages, replacing the less efficient high-pressure sodium lamps just as they in turn replaced the older sodium and mercury lamps installed in the 1960s and ’70s.

But why not go further? Instead of drawing power from underground cables, why not fit lithium-ion batteries in the streetlight posts and top the lamp off with a solar panel and a wind generator? The one-off cost savings of not providing a mains power connection, and the lifelong savings of electrical energy would help offset the additional manufacturing cost. Once installed, the street lighting would be entirely green.

Greening the desert – Some deserts have ready supplies of seawater nearby, parts of the Sahara, the Kalahari, the west coast of South America, and regions of Southern Australia spring to mind. Building wind farms and solar farms in these coastal deserts would allow for green desalination, green pumping of the fresh water far inland, and the literal greening of large areas of desert. Not only could the land be used for crops, it might also be possible to establish areas of forest, thus sequestering significant amounts of carbon. And evapotranspiration would reduce the temperature and increase the humidity of the climate downwind of the greened zones. If a sufficient area could be greened in this way, clouds might form and reflect away some of the incoming solar energy

Solar car parks – Many towns and cities have public parking areas, asphalt ‘deserts’ where cars bake in the summer heat while we are shopping or working. Why not cover these areas with solar farms supported on frameworks above the cars and pedestrians? Most towns could generate as much power this way as would a small solar farm in the countryside. As a bonus, radiant heat transfer would be partially blocked from the covered area, so parked cars would stay cooler on hot days, and warmer on cold nights. And pedestrians would get shelter from rain and snow.

Using electric cars to balance demand – Electric cars have considerable amounts of energy storage and this could be used to help smooth power peaks and troughs. Cars plugged in overnight at home or during the day in town and workplace car parks would absorb wind power when excess is available, and return some of it to the grid at times of peak demand. Combined with dedicated battery storage facilities, this would make a change to fully renewable energy supplies possible.

Generating methane – Elon Musk is considering using green electrical energy to extract carbon dioxide from the air and combine it with hydrogen from water to generate methane and oxygen. Using the methane as a fuel would consume oxygen and produce carbon dioxide and water – a closed system. Originally this idea was intended to allow refuelling of SpaceX’s Starship on the surface of Mars, but he is now looking at the idea of using the same process on Earth to fuel the spacecraft. Extending the idea, methane has potential to be used as a storable fuel for air, sea and land travel. Clearly, as methane is a potent greenhouse gas, it will be essential to burn it in an oxygen-rich manner to make sure none escapes.

Using ocean trenches – Why not place organic materials (including plastic waste) in the subduction zones in deep ocean trenches where the material would be buried as layers of silt are deposited naturally, and in the very long term would be carried down by plate tectonics and processed by heat and pressure into simpler, harmless molecules.

Solar farms in polar regions – This is, perhaps, the oddest of ideas -but aspects of it may have some merit. Incoming radiation from the sun comes from low in the sky during a polar summer. Solar panels would need to be angled close to vertical and would throw very long shadows; they would need to track the sun across the sky, east to west. The shadows would provide some cooling by absorbing incoming solar energy, reducing the melting of ice and snow in the shadows. But what to do with the electrical power? I suggest radiators at the focus of parabolic reflectors pointing vertically upwards, sending the energy back into space. The atmosphere is transparent at visible, radio, and some infra-red wavelengths. Rather than trying to cover large areas, the idea would be to protect specific areas at risk of losing the white, reflective cover of snow and ice. This scheme might be a bit zany, but perhaps it will spark other minds to come up with more practical alternatives.

Solar rooftops – By no means a new idea, but many industrial and commercial buildings do not currently have solar power generation installed. Reduced taxation could encourage more rooftops to supply energy in this way, and it would be generated in towns and cities, right where it is needed. Lobby governments and local authorities to encourage this.

Burying organic matter – Organic waste and/or purpose grown biomass could be air dried and packed into disused coal mines or other available spaces. Sequestered in this way, the carbon content would be removed from the atmosphere, reducing the levels of carbon dioxide that drive global heating.

Over to you! – Maybe you can come up with some green energy ideas of your own; this planet needs all the good ideas we can provide. Anything that reduces our level of consumption or enables us to live in harmony with the natural world should be publicised and adopted as widely as possible. If you have a good idea, leave a comment and tell us about it. And make sure to share it as widely as you can.

Cirencester Wharf

There would have been bargaining and haggling, tobacco smoked and ale downed

Modern residents of Cirencester may not know that the town once had a wharf where canal boats tied up to load and unload goods of all kinds, including coal, manufactured goods, and timber. There were small hand-operated cranes on the quayside to help with handling heavy items.

The canal was a branch from the main Thames & Severn Canal that ran through Siddington and is currently being restored by the Cotswold Canals Trust.

So where was the wharf?

The wharf lay at the bottom of what is now Querns Hill, less than half a mile south of where Cricklade Street meets the Market Place. It was an easy trip by horse and cart for any of the businesses in the town in the late 18th and early 19th centuries, and would have been a bustling hub of activity. The area was large enough to turn arriving barges for the trip back to Siddington; imagine the sounds and smells as horses were harnessed and roped for departure or released to rest and graze after arrival. Money would have changed hands as goods were loaded or unloaded from carts and dreys. There would have been bargaining and haggling, tobacco smoked and ale downed, jokes and banter and laughter, bread, cheese and meat passed around. People would have greeted one another and said their goodbyes because barges were used to carry passengers as well as goods.

Does anything remain?

Surprisingly, yes! Parts of the towpath remain as footpaths and can still be walked, though the canal has been filled in and there’s no sign of it in the area near the wharf. There are dry stone walls that were once the boundary walls of the canal; you can see these when you know what to look for. And it’s not hard to trace the route of the canal on foot.

Begin near the bottom of Querns Hill, where it meets Querns Lane and Sheep Street, find the view in the location photo below.

Location of the wharf

You are now looking at the site of the old wharf. It stretched from close to the building on the left (beyond the parked cars and the wall) across to the right hand edge of the photo. The canal leading from the wharf headed directly through the building in the centre of the photo and passed to the right of the trees in the centre.

The trees follow the line of the old towpath

The photo above shows the same trees but looks back towards the wharf; the buildings on the left are close to those in the first photo. The canal would have more or less followed the road from the buildings on the left right up to the green bin. Turning 180° from this view there is a house built over the route of the canal, but walking around it, the footpath between the houses is again the old towpath. What’s more, a dry stone wall on the left hand side of this path is almost certainly the old boundary wall that ran along both sides of the canal. The wall is high here, about 2 m, but in farmland the wall was only 1 m or so.

The old towpath and boundary wall, the canal was where the grass is

I was quite surprised to find so much remaining and still identifiable. Local history can be quite fascinating and sometimes the detective work is easier than expected. It would be nice to have some of these remains marked and explained on noticeboards.

If anyone reading this is interested in helping to research the Cirencester Branch of the canal, please leave a comment below and I’ll make contact.

The family business prospered for many years

(See indexes on other topics)

This was the family business, founded in 1795. It prospered for many years, growing and selling nursery stock to other businesses, the government, and to the general public. It ceased trading in 1984 and the garden centre business was sold to Country Gardens PLC, although the company was not officially dissolved until 1994.

Spiritual melody

Everyone present should be free to begin a song

Part 6 of a series – Spiritual melody

Eat together | Index | No later posts >

When we think about church music, we usually think in terms of something that’s organised in advance and is played by a band of some kind. Often there’s a worship leader. Over the centuries church music has developed in parallel with the changes in secular music, some examples include Gregorian Plainsong, the chanting of psalms, hymns from hymnbooks accompanied by an organ, informal choruses in house meetings, and more recently bands playing in styles drawn from modern secular music and sometimes of excellent professional standard.

How does that compare with music in the early church? We do have some clues; for example, Paul writes about it briefly in Ephesians 5. In verse 18 he tells us

[Be] filled with the Spirit as you sing psalms and hymns and spiritual songs among yourselves, singing and making melody to the Lord in your hearts.

So it seems likely that singing involves inspiration, literally singing as and when and how the Holy Spirit leads. And that would be the very opposite of what we find in many church meetings where the music is led by a person and/or a band at the front and the congregation joins in. It is sometimes the case that people may, in the process, be caught up emotionally and, perhaps, spiritually. But this is never guaranteed and there’s limited freedom to initiate a new song, sing in the Spirit, or be fully free in praise and worship.

Informal and spiritual worship

So what is Victor Choudhrie suggesting? (See the quote below.) Quite simply he is saying that when we meet, at home, in small groups, after sharing a meal, we should forget organised, planned in advance music with a band. Instead, as we pray and worship and teach one another, everyone present should be free to begin a song if they feel led by the Holy Spirit to do so. Not only that, they should feel free to sing in a tongue, or use their voice with no words at all, sing alone or together, pouring out their hearts to the Lord and to one another. As with everything else – complete freedom in music!

Who is it for? Why are we singing? I’m sure you already know the answer! It’s for the Father, Papa, Abba, Daddy, Yahweh, the Mighty One, Elohim – sing to him in praise and worship. And it’s for the Son, Jesus, Yeshua, Yahshua, the Messiah, Christ, our King, our Redeemer and our Rescuer – sing to him in praise and worship. And it’s for his Spirit, the Spirit of Christ, the Holy Spirit, our Comforter, our Guide, our Cousellor and Advocate, the One who prompts us to sing – sing to him in praise and worship. Sing to the Three in One, the Everlasting Mystery! He is with us, and in us, and amongst us. How could we not sing?

Here’s what Victor Choudhrie has to say about it:

Replace professional music with believers speaking to each other in psalms and spiritual songs, making melody in their hearts to the Lord. OT worship required the sacrifice of four-footed beasts; the NT celebrates by offering two-legged Gentiles as a living sacrifice. The meta-church is a discipling hub and not a singing club. Eph 5:19; Col 3:16; Rom. 15:16

Questions:

  • How can we best give the Holy Spirit freedom in our singing?
  • Is it helpful or unhelpful to restrict singing to a particular slot in a meeting?
  • If our hearts are full of praise, are we more or less likely to sing?
  • If we sing, are our hearts more or less likely to become full of praise?

Hand, foot and eye

At a time when the disciples are well aware of Jesus’ glory, power, transcendence, and authority, they ask, ‘Who’s the greatest in the kingdom of heaven?’

I was reading Matthew 18 this morning, and thought that there are depths in this chapter that can only be grasped when we see things from a kingdom perspective.

In chapter 17, Yahshua reveals his glory to Peter, James and John; deals with the disciples’ lack of faith; speaks of his death and resurrection; and explains that he and his followers are not subject to the demands of religion because they are already part of his holy kingdom. The scene is set, Jesus has demonstrated that he has all the glory, all the power, transcends death, and is subject to no human authority. These factors are all relevant to our understanding of chapter 18, which begins with the words ‘At that time’.

A three-year-old child (Wikipedia)

So, at a time when the disciples are well aware of Jesus’ glory, power, transcendence, and authority, they ask, ‘Who’s the greatest in the kingdom of heaven?’ As he often does, Jesus answers indirectly. He calls over a small child to place amongst them, and tells them clearly that they need to be childlike or they won’t make it into the kingdom of heaven at all. Only the humblest adult can be great in the kingdom, and welcoming such a person is, in reality, welcoming Christ himself.

Furthermore, even being drowned is better for me than putting obstacles in the way of a humble believer; Yahshua isn’t saying I must be put to death, he’s saying I’m already worse than dead! If I cause such stumbling I’m not really one of his followers at all. In verses 8 and 9 Yahshua describes how my hand, my foot, or my eye might cause me to stumble. So it’s what I choose to do, where I decide to go, and what I pay attention to that puts me at risk. There’s a challenge here for all of us: don’t do, go to or look at anything that might cause us to fall. Avoid actions, circumstances and sights that are unhelpful. Stay humble, remain in his presence, and we will share in his glory, power, life and authority. Now that’s good news!
