Reshaping how we can talk positively about the climate crisis – part 2:  Buildings 

February 2025

How can we talk about the climate crisis in a way that sounds encouraging?

The climate crisis is an existential threat which is certainly not good news. Its causes and impact are diverse and numerous such that it is hard to pin down ‘This is the cause’ and ‘This is the solution’. It is hard to quantify ‘This is how it will effect you’ and ‘This will be the time table.’ 

All this makes it difficult to find a way of talking to people about the crisis and how we might respond.

So here are some thoughts that might help.

Warmer – and cooler – homes!

Improved insulation for domestic and other buildings makes them more comfortable for occupants and reduces the costs of heating/ cooling. Studies show that all houses built before 1990, and 75% of those built before 2010, have inadequate insulation which means that both the country will struggle to reach net zero and occupiers will either be paying unnecessarily high heating bills and/ or living in cold damp conditions. For January 2023 the Resolution Foundation estimated that “families in energy-inefficient homes will be facing monthly gas bills £231 higher than those who live in equivalent homes that already meet the Government’s efficiency target (EPC C).” https://www.resolutionfoundation.org/publications/cutting-back-to-keep-warm/

Ensuring all buildings – not just domestic ones, but office buildings, schools, prisons, hospitals etc – will benefit occupants (making their environment comfortable and healthy) and reduce running costs.

Well insulated buildings offer all year round comfort and benefit everyone.

Sustainable buildings

Buildings themselves can contribute to a better environment for us all. Installing solar panels on roofs and elsewhere – eg over car and cycle parks, on top of bus shelters etc – can boost energy production and provide locally based energy without the need for substations and long distance power lines. They can also be a source of local community income. https://www.bbc.co.uk/news/business-65626371

Installing water butts, grey water systems, SUDs (surface urban drainage) that absorb rainfall, are all easy ways of reducing flooding and pollution risks. Such things are most economically included at the design stage but can still justifiably be added as a retrofit. https://www.susdrain.org/

New buildings can be designed with over hanging eves and recessed windows to increase shading against summer heat and also helping to shelter the building from heavy rain and wind. Retrospectively verandas and sun shades can be added or plants trained up the sides of buildings and across pergolas to create a similar outcome. https://www.solinear.co.uk/the-ultimate-guide-to-external-solar-shading-solutions-in-the-uk/

Trees can be planted nearby to provide shade from the sun, cooling via respiration from their leaves,  and at the same time reducing flooding risks as their leaves and roots slow the flow of water and increase absorption in the earth beneath. 

Sustainable buildings are also ones that have a long life. Keeping buildings in good repair prolongs their life, creates employment and ensures that the buildings remain comfortable and safe for their occupants. 

Buildings designed and maintained for sustainability provide comfortable, safe and healthy places, and

Reflection with readings below

“Cursed are those who trust in mere mortals” In whom then or where should we place our trust?

As Christians, the answer is obvious: in God! In that wisdom of God, revealed to us in Christ Jesus, that we should love and care for other. And as part of the living planet, the answer is equally obvious, in nature. 

Nature – the world and all its flora and fauna, its natural resources and self-sustaining cyclical systems – is what God has (and is) creating. It is God’s art work, God’s gift. It is good! And it is to be trusted! The world, all its natural resources, can feed and sustain all living beings – if we humans do not misuse or abuse it.

Those who trust in God, says Jeremiah, are like a tree planted by a stream. Trees are amazing things – with roots that embrace the earth, that interconnect with the soil and communicate via mycorrhizal fungi. Through their roots they feed and sustain each other and also the soil on which they depend. 

Trees grow branches from a secure base that provide strength and support, lifting up their leaves to reach the sunlight from which they produce life-giving energy and release oxygen. Trees create and sustain that hospitable atmosphere that allows all of us creatures to live. Trees provide homes and living spaces for a multitude of other beings – flora and fauna. They create essential microclimates. They create rainfall in the right places and limit flooding. They nurture the soil and ensure the stability of the ground. 

Just imagine what the world would be like if we humans could achieve even half of that! A world where people communicate with one another – the good news and the bad which really means telling the truth. A world where people help each other, they support the ones who provide food and shelter, those who sustain life. A world where people protect each other from harm. A world where people focus on the common good, on the wellbeing of the community.

And isn’t that what Jeremiah is saying we can be like if we trust enough in God’s wisdom? Jesus is giving us the same message. When he says, “Blessed are the hungry for they shall be filled”, Jesus is not saying just wait a while and God will wave a magic wand and food will appear. No Jesus is saying when you are true to God’s way, when you live the way God desires, then by virtue of your ability to live  righteous lives you will perforce never let anyone go hungry. You will never let anyone go uncared for. You will never let anyone go uncomforted. You will share your riches: then no one will be rich and all  being poor will be blessed! 

But instead humans seem dead set on looking only after themselves. We seek only what profits us, and any riches we gain, we keep only for ourselves – stashed away so that no one else can benefit from what we have ‘earnt’. We humans eschew cooperation, and decline to go out of our way to help others unless the reward to us is even greater. We are not driven by love but by profit, and we seem unable to envisage any different sort of economy.

Last Friday I took part in two actions. One inviting the Church of England to take the lead in rewilding to address the UK’s position as one of the most nature-depleted nations. The other calling on the government to stop subsidising the burning of trees at the Drax power station.

If it is in God we trust, and if it is the natural world that God has given us that provides us with a safe, provident and beautiful, habitable home, then why are we not doing more to protect trees in particular and biodiversity more generally?

If all we do is seek riches, then maybe we will deserve the woes that Jesus foretells?

What can we do this week to align ourselves with God’s wisdom, to love and cherish all our neighbours, to love and restore biodiversity – to value the common home we share – and to pursue justice not profits, to place our trust in God?

Jeremiah 17:5-10

Thus says the Lord:

Cursed are those who trust in mere mortals
and make mere flesh their strength,
whose hearts turn away from the Lord. 

They shall be like a shrub in the desert,
and shall not see when relief comes. 

They shall live in the parched places of the wilderness,
in an uninhabited salt land. 

Blessed are those who trust in the Lord,
whose trust is the Lord.

They shall be like a tree planted by water,
sending out its roots by the stream.

It shall not fear when heat comes,
and its leaves shall stay green;

in the year of drought it is not anxious,
and it does not cease to bear fruit.

The heart is devious above all else;
it is perverse–
who can understand it? 

I the Lord test the mind
and search the heart, 

to give to all according to their ways,
according to the fruit of their doings. 

Psalm 1 

1 Happy are they who have not walked in the counsel of the wicked, *
nor lingered in the way of sinners,
nor sat in the seats of the scornful!

2 Their delight is in the law of the Lord, *
and they meditate on his law day and night.

3 They are like trees planted by streams of water,
bearing fruit in due season, with leaves that do not wither; *
everything they do shall prosper.

4 It is not so with the wicked; *
they are like chaff which the wind blows away.

5 Therefore the wicked shall not stand upright when judgment comes, *
nor the sinner in the council of the righteous.

6 For the Lord knows the way of the righteous, *
but the way of the wicked is doomed.

1 Corinthians 15:12-20

Now if Christ is proclaimed as raised from the dead, how can some of you say there is no resurrection of the dead? If there is no resurrection of the dead, then Christ has not been raised; and if Christ has not been raised, then our proclamation has been in vain and your faith has been in vain. We are even found to be misrepresenting God, because we testified of God that he raised Christ–whom he did not raise if it is true that the dead are not raised. For if the dead are not raised, then Christ has not been raised. If Christ has not been raised, your faith is futile and you are still in your sins. Then those also who have died in Christ have perished. If for this life only we have hoped in Christ, we are of all people most to be pitied.

But in fact Christ has been raised from the dead, the first fruits of those who have died.

Luke 6:17-26

Jesus came down with the twelve apostles and stood on a level place, with a great crowd of his disciples and a great multitude of people from all Judea, Jerusalem, and the coast of Tyre and Sidon. They had come to hear him and to be healed of their diseases; and those who were troubled with unclean spirits were cured. And all in the crowd were trying to touch him, for power came out from him and healed all of them.

Then he looked up at his disciples and said:

“Blessed are you who are poor,
for yours is the kingdom of God.

“Blessed are you who are hungry now,
for you will be filled. 

“Blessed are you who weep now,
for you will laugh. 

“Blessed are you when people hate you, and when they exclude you, revile you, and defame you on account of the Son of Man. Rejoice in that day and leap for joy, for surely your reward is great in heaven; for that is what their ancestors did to the prophets.” 

“But woe to you who are rich,
for you have received your consolation. 

“Woe to you who are full now,
for you will be hungry. 

“Woe to you who are laughing now,
for you will mourn and weep. 

“Woe to you when all speak well of you, for that is what their ancestors did to the false prophets.”

Trust in the Lord and be doing good; dwell in the land and be nourished with truth.
 Let your delight be in the Lord and he will give you your heart’s desire.
Commit your way to the Lord and put your trust in him, and he will bring it to pass. Psalm 37:3-5

You Lord are the bread of life;

feed us with your wisdom.

Our meat is to do the Father’s  will.

guide us in all we do

Whenever we eat or drink

Let it be to the glory of God.

Reading Mark 6: 38-44 ( from The Message)

But he was quite serious. “How many loaves of bread do you have? Take an inventory.”

That didn’t take long. “Five,” they said, “plus two fish.”

 Jesus got them all to sit down in groups of fifty or a hundred—they looked like a patchwork quilt of wildflowers spread out on the green grass! He took the five loaves and two fish, lifted his face to heaven in prayer, blessed, broke, and gave the bread to the disciples, and the disciples in turn gave it to the people. He did the same with the fish. They all ate their fill. The disciples gathered twelve baskets of leftovers. More than five thousand were at the supper.  

Table Piece

Around the table, smallest to largest, 

youngest to oldest – comfortable and companionable.

Bread, first mixed and kneaded, 

shared together at the table.

Wisdom, debated and pondered,

gathered from around the table. 

Gentle chiding, loving acceptance, laughter –

differences reconciled at the table.

Thanks given, prayers said, hands clasped 

a place of worship at the table.

Kith and kin, friends – all welcome: love 

a community built around the table.

Prayers

We give thanks O Lord, for the food we have to eat, 

for the opportunities we have to eat together, 

for the times we gather to share and  learn together, 

and for the joy of worshipping at your table. 

We pray Lord, for all who struggle to get food to eat, 

all who lack the companionship of friends and family, 

all who are exploited and all who are fall prey to disinformation, 

and for all who have yet to feel included at you table. 

Stir us Lord, to respond with generosity and determination 

to feed the hungry, 

to transform the inequalities of society, 

to reach out to those starved of love,

and to nourish all with your word.

Amen.

The Psychology of Peace

14th February 2025

The other week I went to the Imperial War Museum to see their exhibition ‘War and the Mind’ which was exploring the psychology that prompts people to go to war, the psychological impact on both combatants and noncombatants, how army leaders maintain moral, ditto for civilians in war zones, how people try and look after their own mental well-being etc. Towards the end of the exhibition one display focused on how the UK government set out to persuade British people to reshape their view of German people (distinguishing between war criminals and the ordinary person) and to understand the need to provide both jobs for the German populace and an education for the children so that they wouldn’t behave as their forebears had. 

This struck me as so important. We can’t make peace until we see the other as someone of equal value as ourselves, until see the other as our neighbour to be loved. There can be no place in peace for revenge or hostile discrimination. Yet even in the UK there are still people willing to make jokes about Germans referencing the war, to make jokes that are predicated on the British being some sort of superior victor – or a British Bulldog. 

Such attitudes then filter into other areas of life – that Britain is obviously a world leader in any and every field of endeavour, that we have nothing to learn from others, that we have no need to cooperate with anyone else, that the way we do things must be the best – the only – way.

This blinkered view that can only see self as right and everyone else as wrong, is repeated in other nations and other conflicts around the world. Can there be peace in Gaza until everyone sees the other as a brother or sister? Can there be global cooperation and agreement until everyone sees the good in everyone else? 

So the question is how do we change we think and act both as individuals and as communities and nations?

Grey water is water that has been used for washing hands, bathing, washing clothes, washing vegetables etc. Grey water systems that collect and treat grey water, often combining it with collected rainwater, can be plumbed in to flush toilets but these can be expensive, especially when retrofitted. 

In summer months, we may already practice grey water harvesting – collecting water from showers and washing machines to water the garden. Ideally such water should not be stored from more than a day because pathogens from what we have washed may multiply especially when the water is warm.

The Centre for Alternative Technologies has this advice about washing machine water – “If you wish to irrigate with water from a washing machine then use a low-sodium detergent, because sodium damages plants and degrades soil (liquid detergents usually contain less salt than powders). Avoid phosphorus as well, because this causes algal blooms if it collects in ponds or rivers. Otherwise, the water has only very small and well diluted quantities of pathogens or grease and therefore these should not be of concern.” https://cat.org.uk/info-resources/free-information-service/water-and-sanitation/rain-and-grey-water/

And the RHS says – “Plants can be watered with shower, bath, kitchen and washing machine water (from rinse cycles), collectively referred to as ‘grey’ water. It varies in quality and may contain contaminants such as soap and detergent. Fortunately, soil and potting composts are effective at filtering them out, and the residues can sometimes act as a mild fertiliser. To minimise bacterial growth, grey water should be saved for only 24 hours, unless filtered through a reed bed or professionally designed system. It is best applied by watering can; grease and fibres can clog irrigation systems.” https://www.rhs.org.uk/science/gardening-in-a-changing-world/water-use-in-gardens/using-grey-water

In our home, we collect hand wash water and use it to flush the toilet when ‘yellow’ and use the toilet flush when ‘brown’.

Waterfalls are dramatic natural features because of their power and beauty. The power of falling water is utilised by water wheels and hydro power plants. Its power is replicated by power showers and power hoses – but in those situations we may want to think whether the amount of energy and water used is reasonable in a world where we are already overusing limited resources.

That said, another way of saving water and energy is to shower less often. Most of us don’t need to shower every day – we can wash bits of ourselves as necessary in a basin and still smell clean and fresh.

Some 30 years ago we lived for a year in Zimbabwe, during a drought. Households were rationed to initially 50 litres of water a day (between five of us). We were able to send our washing to the laundry but for all other needs had to plan how we used our water. Apart from what we drank, every drop was reused – cooking and washing up water flushed the toilet, baths (we used a baby bath) were shared etc. We weren’t allowed to water the garden as all waste water was need to keep the sewers flowing. 

That was an extreme situation, but thinking about how we use every drop of water is relevant at any time.

The drinking water that comes into our homes, comes at an environmental cost. The water has to be purified to a drinkable standard, it has to be stored and pumped, all of which requires energy and resources – pipe work, concrete for reservoirs etc. Once used it has to be treated again to be clean enough to return into rivers and waterways or to be recycled again as drinking water. If we are more careful about not wasting water, then we are improving the sustainability with which we live. 

The climate crisis increases the likelihood of both droughts – when the benefits of conserving water are most obvious – and floods. Floods can lead to the contamination of drinking water as well as causing difficulties in remove waste water and sewage.

Climate change is triggering more extreme weather conditions including heavy rain and flooding. Water butts are great in the summer to help tide us over dry spells when plants need watering, but they can also be useful in slowing the flow of water into the drains. 

It needs a bit of thinking but if we allow water butts to drain slowly after heavy rain into the drains, then they can be a temporary store for excess water next time it rains – a sort of mini water meadow or overflow reservoir. One precaution that is needed is that empty water butts are easily blown over in strong winds so you may want to put some bricks in the bottom of the water butt or tie the butt to something solid.

Reflection with readings below

God has created a world that is continually evolving. It is network of changing ecosystems inhabited by an infinite variety of species. Amongst these humans stand out for their capacity reshape the world. The writers of scriptures have known for millennia that humans have the ability to act for good or for ill. A passage in Deuteronomy tells the people that they can chose to do what is right and enjoy fruitful and joyous lives, or they can chose to do what is wrong and suffer lives of destruction and misery. And the situation hasn’t changed. 

Today’s readings tell how God – aware of human frailties – time and again calls on individuals to proclaim God’s wisdom, God’s gospel of salvation, to the peoples of the world. God’s call to Isaiah

 was dramatic and profound. The message Isaiah was called to speak was at a time of great tension and threat. It was not an easy message to proclaim, nor was it easy to hear. In fact the people chose to close their ears and ignore God’s warnings. Catastrophe followed.

Paul was clearly aware of the importance of the message he had to share, and equally clear that his role as a chosen messenger was not based on any merit on his part but purely on the grace of God. In fact Isaiah had shared the same sense of inadequacy. And Simon Peter too.

But whereas Isaiah’s encounter with God was full of awe and wonder, smoke and angels, Simon Peter’s boarders on the mundane. He was doing nothing more than his usually daily job. The unexpected catch of fish was certainly amazing but not out of this world. Yet the call, his encounter with Jesus, struck him to his core and was absolutely life changing. Now he was to use  his skills for a different task, that of reaching out to and drawing in his fellow humankind, to allow them to encounter Jesus and to take on board a new way of living – the way of the Gospel, the way of God’s wisdom.

Here we are two millennia later. The world is in a vulnerable place and now – as always – people need to hear the word of God, to hear the wisdom that will lead them to choose the way of right living, of fruitfulness and joy. 

And we are the people who must speak! 

What must we say, what must we proclaim as the word of God to the world?

That we face an existential crisis of our own (human) making. 

We have pumped so much carbon dioxide into the atmosphere (as well as other greenhouse gases) principally through burning fossil fuels at ever increasing rates. The warming effect on the atmosphere has already activating  tipping points and feed back loops which are accelerating the impact. We’re seeing year on year increases in temperatures that are exceeding the expectations of the scientists; we’re seeing increasingly frequent and intense adverse weather events – floods, droughts, wildfire, storms, heat domes; we’re seeing melting glaciers and ice caps, rising sea levels and more frequent land and mud slides. We’re seeing the slowing of the Atlantic Meridian Overturning Current. When this current fails to circulate hot and cold waters, we in the UK will find ourselves in a land that has a climate compatible with that in Greenland. At the same time UK’s land area will be shrinking as sea levels rise by 50-70cm. This, on the present trajectory, will happen in the life time of children who have already been born. This is going to be the probably scenario they will face as they enter the job market and – perhaps – choose whether or not to become parents themselves.

We cannot prevent all of the adverse effects of the crisis – many are already baked in. But we can yet limit the worst impacts, we can protect against the most adverse consequences, we can help one another to live as safely and as comfortably as possible, but – and this is a big BUT – only if we act now on the science we have. Only if we act now for the common good – that is for the good of everyone with equality and justice – and not allow the interests of a minority to take precedence. 

We need to engage the attention and the commitment of governments and organisations, of companies and and trade groups, of workers and investors, of social groups and individuals. 

We have to act now. We have to act with urgency. We need to make substantial step changes so that we are more than half way to our goals of global sustainability in the next five years. We should write to our MPs, to Rachel Reeves, the Chancellor, and Ed Miliband,  secretary of state for energy security and net zero. We should seek out campaigns and support them, sign petitions, boycott those companies that are supporting the continued expansion of fossil fuels. We should review our financial arrangements – do our banks, insurers, pension providers etc support fossil fuels industries? We should look at our own lifestyles – are we walking the talk? We should be looking out for groups and communities being marginalised and penalised by the climate crisis and the failure to make a just transition to a sustainable world.

This is the gospel message: we need to love our neighbours as ourselves – not just the neighbour next door, but the neighbours in the next town, across the next boarder, and in the farthest parts of the globe. We need to tend and care for the planet knowing that it is the unique  common home that God created for us. We need to love God with our whole being because it is that love that will motivate us to act.

Isaiah 6:1-8, [9-13]

In the year that King Uzziah died, I saw the Lord sitting on a throne, high and lofty; and the hem of his robe filled the temple. Seraphs were in attendance above him; each had six wings: with two they covered their faces, and with two they covered their feet, and with two they flew. And one called to another and said:

“Holy, holy, holy is the Lord of hosts;
the whole earth is full of his glory.” 

The pivots on the thresholds shook at the voices of those who called, and the house filled with smoke. And I said: “Woe is me! I am lost, for I am a man of unclean lips, and I live among a people of unclean lips; yet my eyes have seen the King, the Lord of hosts!”

Then one of the seraphs flew to me, holding a live coal that had been taken from the altar with a pair of tongs. The seraph touched my mouth with it and said: “Now that this has touched your lips, your guilt has departed and your sin is blotted out.” Then I heard the voice of the Lord saying, “Whom shall I send, and who will go for us?” And I said, “Here am I; send me!” And he said, “Go and say to this people:

`Keep listening, but do not comprehend;

keep looking, but do not understand.’ 

Make the mind of this people dull,
and stop their ears,
and shut their eyes,

so that they may not look with their eyes,
and listen with their ears, 

and comprehend with their minds,
and turn and be healed.” 

Then I said, “How long, O Lord?” And he said:

“Until cities lie waste
without inhabitant, 

and houses without people,
and the land is utterly desolate; 

until the Lord sends everyone far away,
and vast is the emptiness in the midst of the land.

Even if a tenth part remain in it,
it will be burned again, 

like a terebinth or an oak
whose stump remains standing
when it is felled.” 

The holy seed is its stump.

Psalm 138

1 I will give thanks to you, O Lord, with my whole heart; *
before the gods I will sing your praise.

2 I will bow down toward your holy temple
and praise your Name, *
because of your love and faithfulness;

3 For you have glorified your Name *
and your word above all things.

4 When I called, you answered me; *
you increased my strength within me.

5 All the kings of the earth will praise you, O Lord, *
when they have heard the words of your mouth.

6 They will sing of the ways of the Lord, *
that great is the glory of the Lord.

7 Though the Lord be high, he cares for the lowly; *
he perceives the haughty from afar.

8 Though I walk in the midst of trouble, you keep me safe; *
you stretch forth your hand against the fury of my enemies;
your right hand shall save me.

9 The Lord will make good his purpose for me; *
O Lord, your love endures for ever;
do not abandon the works of your hands. 

1 Corinthians 15:1-11

I would remind you, brothers and sisters, of the good news that I proclaimed to you, which you in turn received, in which also you stand, through which also you are being saved, if you hold firmly to the message that I proclaimed to you–unless you have come to believe in vain.

For I handed on to you as of first importance what I in turn had received: that Christ died for our sins in accordance with the scriptures, and that he was buried, and that he was raised on the third day in accordance with the scriptures, and that he appeared to Cephas, then to the twelve. Then he appeared to more than five hundred brothers and sisters at one time, most of whom are still alive, though some have died. Then he appeared to James, then to all the apostles. Last of all, as to one untimely born, he appeared also to me. For I am the least of the apostles, unfit to be called an apostle, because I persecuted the church of God. But by the grace of God I am what I am, and his grace toward me has not been in vain. On the contrary, I worked harder than any of them–though it was not I, but the grace of God that is with me. Whether then it was I or they, so we proclaim and so you have come to believe.

Luke 5:1-11

Once while Jesus was standing beside the lake of Gennesaret, and the crowd was pressing in on him to hear the word of God, he saw two boats there at the shore of the lake; the fishermen had gone out of them and were washing their nets. He got into one of the boats, the one belonging to Simon, and asked him to put out a little way from the shore. Then he sat down and taught the crowds from the boat. When he had finished speaking, he said to Simon, “Put out into the deep water and let down your nets for a catch.” Simon answered, “Master, we have worked all night long but have caught nothing. Yet if you say so, I will let down the nets.” When they had done this, they caught so many fish that their nets were beginning to break. So they signalled their partners in the other boat to come and help them. And they came and filled both boats, so that they began to sink. But when Simon Peter saw it, he fell down at Jesus’ knees, saying, “Go away from me, Lord, for I am a sinful man!” For he and all who were with him were amazed at the catch of fish that they had taken; and so also were James and John, sons of Zebedee, who were partners with Simon. Then Jesus said to Simon, “Do not be afraid; from now on you will be catching people.” When they had brought their boats to shore, they left everything and followed him.
