Lent – walking dangerous paths

23rd March 2024  

Your word is a lamp to my feet and a light to my path. Psalm 119:105

You Lord, are the source of all good things: 

We praise you.

You call us to tend and care for your creation: 

May we strive to do your will.

You have made us as brothers and sisters with all that lives: 

May we live together in peace.

A reading from Deuteronomy 10:12-13 

So now, O Israel, what does the Lord your God require of you? Only to fear the Lord your God, to walk in all his ways, to love him, to serve the Lord your God with all your heart and with all your soul,  and to keep the commandments of the Lord your God and his decrees that I am commanding you today, for your own well-being.

People who walk as refugees 

struggling under burdens too heavy to unpack, 

want only a safe future.

Merciful God, show us your pathways of love.


People who walk the lonely streets 

wrapped in a dirt-worn sleeping bag, 

want only a bed to call home.

Merciful God, show us your pathways of love.


People who walk across parched fields 

at a pace which hunger dictates, 

want only a square meal each day.

Merciful God, show us your pathways of love.

People who walk gingerly around unexplored ordinances 

ducking out of the sniper’s range, 

want only a foundation for peace.

Merciful God, show us your pathways of love.

People who walk the chicane 

of benefits offices and job centres, of interviews and rejections, 

want only life-fulfilling employment.

Merciful God, show us your pathways of love.

People who walk as massed processions 

bearing placards that express their hopes and fears, 

want only justice and democracy.

Merciful God, show us your pathways of love.

People who walk the corridors of power 

enveloped in self importance and blinkered by nepotism, 

need – surely? – only to walk the streets of lived experience.

Merciful God, show us your pathways of love.

A further reading from Matthew 21:7-11

They brought the donkey and the colt, and put their cloaks on them, and he sat on them.  A very large crowd spread their cloaks on the road, and others cut branches from the trees and spread them on the road. The crowds that went ahead of him and that followed were shouting,

‘Hosanna to the Son of David!
    Blessed is the one who comes in the name of the Lord!
Hosanna in the highest heaven!’

When he entered Jerusalem, the whole city was in turmoil, asking, ‘Who is this?’ The crowds were saying, ‘This is the prophet Jesus from Nazareth in Galilee.’

Merciful God, lead us in the right paths.

Amen.

Carbon sequestration is a formal name given to the processes by which carbon is captured from the atmosphere and stored on a long-term basis. Such long-term storage might include peat bogs, forests, kelp beds etc and may be referred to as ‘carbon sinks’.

Carbon sequestration can be used as a means of  mitigating the effects of climate change. This can be biologically by, for example, planting more forests, restoring peat bogs and wetlands, and re-establishing kelp meadows. This natural sequestration can be enhanced, in the case of forests, by using felled timber to make items such as buildings, furniture etc and keeping those items for hundreds of years. However growing trees for timber needs to be carefully managed to a) maximise the carbon captured by the growing tree, and b) to maximise the flourishing of biodiversity.

Carbon can also be sequestered geologically if the CO2 can be captured  eg from a cement factory. Then the CO2 “can be compressed to ≈100 bar into a supercritical fluid. In this form, the CO2 could be transported via pipeline … and  injected deep underground, typically around 1 km, where it would be stable for hundreds to millions of years.” (https://en.wikipedia.org/wiki/Carbon_sequestration)

The carbon cycle 

The earth’s systems have various ways of absorbing and using carbon dioxide in such a way as to enable life to flourish. Plants absorb carbon dioxide as part of the process of photosynthesis storing the carbon as cellular material  in their leaves, branches etc. Plants release carbon dioxide back into the atmosphere as they respire – breathe. A living growing plant absorbs more carbon dioxide than it releases. When the plant dies, the carbon that has been stored as leaves and branches etc slowly decays – breaks down – and the carbon returns to the atmosphere as carbon dioxide. This is as true of water and marine plants as it is true of land plants. 

 (For a short video describing how trees absorb and use  carbon – https://www.woodlandtrust.org.uk/climate-change/carbon-trees/)

Soil in part is made up of dead plant and animal material which decays slowly overtime. Soil is therefore a storer of carbon.

The seas and oceans also contain carbon dioxide that is dissolved in the water. This carbon dioxide cycles through the water as marine plants take in, store and release the carbon as they grow. Marine waters  and the layers of sediment at the bottom of the seas and oceans store carbon in the same way as does soil. 

This brings us back to an earlier post about how much carbon dioxide there is in the atmosphere (measured in part per million) and the rate at which that concentration is increasing due to human activities – https://greentau.org/2024/02/19/counting-on-day/

The geological history of oil and gas. 

“The formation of oil takes a significant amount of time with oil beginning to form millions of years ago. 70% of oil deposits existing today were formed in the Mesozoic age (252 to 66 million years ago), 20% were formed in the Cenozoic age (65 million years ago), and only 10% were formed in the Paleozoic age (541 to 252 million years ago). This is likely because the Mesozoic age was marked by a tropical climate, with large amounts of plankton in the ocean.

“The formation of oil begins in warm, shallow oceans that were present on the Earth millions of years ago. In these oceans, extremely small dead organic matter – classified as plankton – falls to the floor of the ocean. This plankton consists of animals, called zooplankton, or plants, called phytoplankton. This material then lands on the ocean floor and mixes with inorganic material that enters the ocean by rivers. It is this sediment on the ocean floor that then forms oil over many years”.

  1. The dead plankton, plus algae and bacteria form an organic rich mud.
  2. If the mud remains in an anoxic environment  – lacking in oxygen such as stagnant water – it does not decompose and so retains its carbon content. 
  3. This anoxic environment becomes embedded by subsequent layers of mud, compressing the carbon rich  layer into an organic shale. 
  4. Overtime the shale sinks as more layers are added. At a depth of 2 to 4km the temperatures from the earth’s core plus the increased pressure converts the organic shale to oil shale.
  5. If the temperatures at this depth are between 90 and 160C this oil shale is transformed into oil and natural gas. This will either seep upwards being lighter than water, or maybe sealed in by subsequent layers of impervious rock.

(https://energyeducation.ca/encyclopedia/Oil_formation)

Again it is mind blowing to reflect that these oil and gas deposits that took millions of years in the making, are now being burnt at an annual rate of 6.6 billion tonnes, such that we have 47 years of reserves remaining – should we be foolish enough to want to burn them.(https://www.worldometers.info/oil/) 

We should keep in mind that the IEA warns that a cannot risk developing and burning new oil and gas reserves without exceeding the 1.5C global warming limit.

The Carboniferous era began around 359 million years ago and lasted some 60 million years. It was an era in which life, land and marine, was well established – verdant swamps and forests. Raised oxygen levels in the atmosphere encouraged the evolutionary expansion of land and marine fauna. It is also known as the Age of the Amphibians as these dominated the  environment – later eras saw the evolutionary journey onto mammals. This abundance of plant and animal life as they decayed became coal beds, often forming in shallow seas and swampy areas of the landscape. It was also a time of increased tectonic movement as land masses moved and mountains were formed. Towards the end of the era, increased  glacial activity and climate change brought about the collapse of the Carboniferous rain forests. 

The name Carboniferous comes from the Latin ‘carbo’ for coal and ‘fera’ for carrying or bearing. Ie it was the coal bearing era. An era 60 million years in the making, locking away tonnes of carbon dioxide as coal, it is mind blowing to think that at current consumption levels – 7.25 billion tonnes a year – we have just 133 years of coal left.

What are the risks of climate change?

Here in the UK the risks include:-

  • Extremes of temperatures. Excess deaths during the heatwave of 2022, exceeded 4500 persons. Deaths due to heat will rise as peak temperatures rise. There is also the risk that the higher temperatures will enable disease-carrying insects to migrate north leading to outbreaks of dengue fever and Zika virus. Cold temperatures also cause deaths many of which could be prevented if homes were better insulated.
  • Flooding. Extreme weather events such as strong winds and storms, together with heavier rainfall (warmer air absorbs more moisture) flooding is an increasing occurrence, damaging homes, infrastructure such  as roads and railways, buildings such as schools and hospitals, etc. Storms and strong winds also damage power cables and cause power outages.
  • Extremes of temperature and flooding adversely affect agricultural output and the increased risk of food shortages. The UK imports about 60% of its food, so our food supplies are also dependent on the impact of climate change on food producing countries in other parts of the world.
  • Rising sea levels due to melting icecaps is already threatening coastal communities as well as increasing the risk of flooding  around and upstream of estuaries.
  • Droughts are an increasing feature of climate change with hotter drier summers. For  a nation that is used to having a constant supply of water for drinking, washing, cleaning cars, filling swimming pool, watering lawns and irrigating agricultural crops, using less water is a challenge.
  • Any disruption of normal life due to heat waves, flooding, storms etc affects business output, disrupts education, delays hospital treatments, interrupts deliveries to supermarkets etc.

These are some of the risks and impacts of the climate crisis that we are experiencing in the UK. In other more vulnerable parts of the world, the impacts are even greater.

Fifth Sunday of Lent

17th March 2024

Reflection- readings are below

Throughout Lent the psalms seem to have been chosen for their focus on sin and the grief that causes us. In today’s the psalmist acknowledges his sinfulness – a sinfulness which has been a burden from birth. What the psalmist realises is that the effect of sin is to break down the relationship between him (or her) and God, and that it is only God who cleanse the psalmist of sin and restore in her the gifts of truth and wisdom, to renew his heart and reinvigorate him with God’s Holy Spirit, so bring her back again into that right relationship with God that he desires. 

Sin separates us from God. It separates us from those gifts that enable us to live in harmony with one another and with all creation. As not-God’s-people we are greedy, hurtful, hateful, mean and jealous. We destroy the natural environment. We persecute others. We perpetuate wars and inflict suffering on the innocent. And this is not what God wants. Jeremiah describes God desire to remake the relationship between God and  by writing the law on their hearts, by internalising the law within them –   So that “they shall all know me, from the least of them to the greatest, says the Lord; for I will forgive their iniquity, and remember their sin no more.”

Jeremiah writes in the plural, for sin doesn’t just affect the individual, but the community. Sometimes my sin has a worse affect on my neighbour either as an unintended consequence or as a deliberate act on my part. And that happens repeatedly through communities from the family units to international groups.  We know on one hand what God wants, and we see on the other hand fighting and cruelty, suffering and aggression. And we feel helpless. 

Do we ignore what’s going on and find peace in ignorance? Do we work really hard so that we have no time to worry about anything else? Do we dissolve into a pool of tears? Do we recognise the sin and suffering for what they are, and seek to find a positive way forwards – healing – through God’s faithfulness?

Whilst the psalms during Lent focus on sin, many of the readings have focused more on suffering and how to cope with it. Last week we had the story of Moses’s childhood – a time fraught with risk but which the protagonists reacted to positively – from the persecuted Hebrew mother to the royal princess. Their efforts were rewarded in the short term but I doubt any of them foresaw the long term salvation that will come from their actions. Likewise last week we were reminded that the process of salvation can also be the way cause great pain. We take the best action, accepting pain if necessary, and be confident that in God’s time there will be  salvation – knowing that we are being restored or healed in our relationship with God.

The week before we heard Jesus’s words “Take up your cross and  follow me”.  A reminder that we should not expect life to be easy but be ready to face challenges and undertake hard graft. Where would Moses have been if the princess had said, “I can’t be bothered”? Where would the food banks be if people said, What’s the point? And gave neither food or time.    Where  would the UN aid organisations be if rich nations said, We’re not that rich. And gave neither  money and support? 

Clinging on to your own life, your own desires, sustaining your own selfishness, Jesus told his disciples, is self-destructive. We think we are protecting ourselves but we are cutting ourselves off from real growth, from true fullness of life. Letting go so that we are part of a bigger story, allows us to experience life to the full.

In today’s  gospel Jesus gives us the image of a seed. The seed is the residue of a living plant. It falls to the ground – as if unwanted – but then in the darkness of the soil is transformed. Its inner heart has the potential for life and, breaking out into new growth, becomes more than it ever was! Jesus sees in all of us that same potential. The potential to change the world around us. This vision is there in so many of his parables – the yeast that swells the bread dough, the salt that flavours the whole meal, the candle flame that lights a room, the seed that grows in the good soil etc. 

Sowing and growing. Being willing to let go of self, of self interest, of self importance. Being willing to undergo transformation. The seed grows best in the good soil. Jeremiah tells us  that transformation is about not just the individual but the community. Jesus very directly addresses his words in the plural – “Those who love their life lose it, and those who hate their life in this world will keep it for eternal life” – as he talks to both his disciples and those – here some Greeks – who are drawn to meet Jesus. It is the community and the support of others that enables our seeds to flourish as they grow.

It is we as part of  a community who must relinquish self interest in the interests of the common good. Indeed it is we as a whole community who must relinquish self interest in the interests of the global good. We cannot go on burning fossil fuels and consuming raw materials without pause. We must be ready to forego some consumer goods in order not to deplete the world to the detriment of the whole world. We must let go our desire to be the most important nation, the strongest nation, in order that all nations be treated with equal value. That will be the resurrection light for the whole world.

So let us be brave. Let us be active. Let us let go of wealth and standing and self importance to allow our lives to enrich the whole world. 

How? By standing up and being vocal about the rights of others. In standing up against greed and excess consumption. In standing up and showing love to our neighbour. By drawing strength from Jesus, seeing in him the example to follow, and finding in him the source of the Holy Spirit that will fill us with strength and joy. By being a community of believers that is fed by and empowered by the fellowship of the Holy Spirit.

Jeremiah 31:31-34

The days are surely coming, says the Lord, when I will make a new covenant with the house of Israel and the house of Judah. It will not be like the covenant that I made with their ancestors when I took them by the hand to bring them out of the land of Egypt—a covenant that they broke, though I was their husband, says the Lord. But this is the covenant that I will make with the house of Israel after those days, says the Lord: I will put my law within them, and I will write it on their hearts; and I will be their God, and they shall be my people. No longer shall they teach one another, or say to each other, “Know the Lord,” for they shall all know me, from the least of them to the greatest, says the Lord; for I will forgive their iniquity, and remember their sin no more.

Psalm 51:1-13

1 Have mercy on me, O God, according to your loving-kindness; *
in your great compassion blot out my offences.

2 Wash me through and through from my wickedness *
and cleanse me from my sin.

3 For I know my transgressions, *
and my sin is ever before me.

4 Against you only have I sinned *
and done what is evil in your sight.

5 And so you are justified when you speak *
and upright in your judgment.

6 Indeed, I have been wicked from my birth, *
a sinner from my mother’s womb.

7 For behold, you look for truth deep within me, *
and will make me understand wisdom secretly.

8 Purge me from my sin, and I shall be pure; *
wash me, and I shall be clean indeed.

9 Make me hear of joy and gladness, *
that the body you have broken may rejoice.

10 Hide your face from my sins *
and blot out all my iniquities.

11 Create in me a clean heart, O God, *
and renew a right spirit within me.

12 Cast me not away from your presence *
and take not your holy Spirit from me.

13 Give me the joy of your saving help again *
and sustain me with your bountiful Spirit.

Hebrews 5:5-10

Christ did not glorify himself in becoming a high priest, but was appointed by the one who said to him,

“You are my Son,
today I have begotten you”;

as he says also in another place,

“You are a priest forever,
according to the order of Melchizedek.”

In the days of his flesh, Jesus offered up prayers and supplications, with loud cries and tears, to the one who was able to save him from death, and he was heard because of his reverent submission. Although he was a Son, he learned obedience through what he suffered; and having been made perfect, he became the source of eternal salvation for all who obey him, having been designated by God a high priest according to the order of Melchizedek.

The Gospel

John 12:20-33

Now among those who went up to worship at the festival were some Greeks. They came to Philip, who was from Bethsaida in Galilee, and said to him, “Sir, we wish to see Jesus.” Philip went and told Andrew; then Andrew and Philip went and told Jesus. Jesus answered them, “The hour has come for the Son of Man to be glorified. Very truly, I tell you, unless a grain of wheat falls into the earth and dies, it remains just a single grain; but if it dies, it bears much fruit. Those who love their life lose it, and those who hate their life in this world will keep it for eternal life. Whoever serves me must follow me, and where I am, there will my servant be also. Whoever serves me, the Father will honour.

“Now my soul is troubled. And what should I say—‘Father, save me from this hour’? No, it is for this reason that I have come to this hour. Father, glorify your name.” Then a voice came from heaven, “I have glorified it, and I will glorify it again.” The crowd standing there heard it and said that it was thunder. Others said, “An angel has spoken to him.” Jesus answered, “This voice has come for your sake, not for mine. Now is the judgment of this world; now the ruler of this world will be driven out. And I, when I am lifted up from the earth, will draw all people to myself.” He said this to indicate the kind of death he was to die.

Lent – seeking God’s wisdom

Friday 18th March

“Hey there! All who are thirsty, come to the water! Are you penniless? Come anyway—buy and eat!
Come, buy your drinks, buy wine and milk. Buy without money—everything’s free! Isaiah 55:1

You Lord, are the source of all good things: 

We praise you.

You call us to tend and care for your creation: 

May we strive to do your will.

You have made us as brothers and sisters with all that lives: 

May we live together in peace.

A Reading: Isaiah 55: 6-13 (The Message translation)

Seek God while he’s here to be found,
    pray to him while he’s close at hand.
Let the wicked abandon their way of life
    and the evil their way of thinking.
Let them come back to God, who is merciful,
    come back to our God, who is lavish with forgiveness.

“I don’t think the way you think.
    The way you work isn’t the way I work.”
        God’s Decree.
“For as the sky soars high above earth,
    so the way I work surpasses the way you work,
    and the way I think is beyond the way you think.
Just as rain and snow descend from the skies
    and don’t go back until they’ve watered the earth,
Doing their work of making things grow and blossom,
    producing seed for farmers and food for the hungry,
So will the words that come out of my mouth
    not come back empty-handed.
They’ll do the work I sent them to do,
    they’ll complete the assignment I gave them.

“So you’ll go out in joy,
    you’ll be led into a whole and complete life.
The mountains and hills will lead the parade,
    bursting with song.
All the trees of the forest will join the procession,
    exuberant with applause.
No more thistles, but giant sequoias,
    no more thornbushes, but stately pines—
Monuments to me, to God,
    living and lasting evidence of God.”

A response: 

God’s vision of the world is one of beauty and harmony –

Yet we do not listen,

We will not hear, 

Our eyes are blinkered. 

Lord, in your mercy awaken us to your wisdom.

God’s vision of the world is one of generosity and abundance –

Yet we hoard what decays,

We squabble over wealth, 

Our hearts are greedy.

Lord, in your mercy awaken us to your wisdom.

God’s vision of the world is one of promise and covenant –

Yet we don’t trust God, 

We don’t  trust our brethren, 

Our ways are deceitful.

Lord, in your mercy awaken us to your wisdom.

God’s vision of the world is one of peace and restoration – 

Yet we fight rather than listen, 

We provoke revenge not love,

Our judgements are corrupt.

Lord, in your mercy awaken us to your wisdom.

Feed us with love

Cleanse us of hate

Gift us with compassion 

Restore our trust in humanity

Renew our understanding of nature 

Fill us with joy

Make us again the people of God.

Amen.

The UK government runs a National Adaptation Programme which assesses the risks arising from climate change and how best we can adapt to reduce of cope with these risks – as well as building on any opportunities where we can gain from change. These plans are reviewed and every five years a new National Adaptation Programme is produced. NAP3 covers the period from 2023 to 2028. It includes items such as:

  • “protecting the natural environment
  • supporting business in adapting to climate change
  • adapting infrastructure (for example, our electricity networks and railways)
  • protecting buildings and their surroundings (for example, from hotter temperatures)
  • protecting public health and communities
  • mitigating international impacts on the UK (for example, on food supplies imported from abroad)”

https://www.gov.uk/government/publications/third-national-adaptation-programme-nap3/understanding-climate-adaptation-and-the-third-national-adaptation-programme-nap3

But are the plans sufficiently stringent? 

“Julia King, chair of the adaptation subcommittee of the CCC, said: “The evidence of the damage from climate change has never been clearer, but the UK’s current approach to adaptation is not working. The national adaptation plan published last July, known as Nap3, was the third in a series of five-yearly updates in response to an assessment of climate risks, required under the 2008 Climate Change Act, from the Department for Environment, Food and Rural Affairs.

“But the CCC found that although it was an improvement on previous efforts, the new plan was still inadequate and required improvement before the next scheduled update in 2028.

“King said: “Defra needs to deliver an immediate strengthening of the government’s programme, with an overhaul of its integration with other government priorities such as net zero and nature restoration. We cannot wait another five years for only incremental improvement.”” https://www.theguardian.com/environment/2024/mar/13/uk-climate-crisis-plans-fall-far-short-of-what-is-required-ccc-says?CMP=Share_iOSApp_Other

Advance planning is key in tackling the climate crisis but it also has to be planning that can flex as circumstance change. The Climate Change Committee was preparing the UK’s fifth carbon budget for the period 2028-2032 back in November 2015. It the executive summary the CCC noted that the publishing of the budget was deliberately being timed to come out before COP21 in Paris – the COP where the Paris agreement was drawn up. 

Amongst the various budget proposals – which largely focused on reducing the carbon intensity of energy generation, and of transport – featured things such as hydrogen powered buses no hydrogen for domestic heating. We now know that the science and the markets have gone down the line of electric buses, and that hydrogen has similarly not proved a practicable substitute for domestic heating – rather the trend has, if very slowly, been for heat pumps.

What the writers of the budget could not have predicted was the Covid pandemic which has altered working patterns and changed the pressures on the transport system. Nor could they have anticipated the war in Ukraine and the sharp increase in fuel prices which has served to reduce gas consumption. 

The CCC is now working on the seventh carbon budget (for the period 2038-2042), having issued the sixth budget in 2020 (for the period 2033-2037). The advance notice of that these budgets give on the shape the economy and infrastructure need to take, should help industry with its investment plans but this does rely on the government both sticking to the plans – eg not changing the proposed date for phasing out new petrol engine cars – and facilitating change when unforeseen circumstances arise such as wars and global energy price hikes.
