How can we better adapt to heat waves?

These are some initial thoughts on things that we could do as individuals, as communities and as a society.

  1. Insulate all buildings – insulation helps maintain a comfortable internal temperature, warm enough in winter and cooler enough in summer. Think how a cool bag or thermos flask can be used both to keep cold things cool and hot things warm.
  2. Government and local authorities can ensure that this happens through mandates, loans and grants.
  3. ‘Enough’ is a key word – warm enough in winter maybe 16-18C whilst cool enough in summer may be 24-26C.
  4. As well as insulation, adaptation to buildings – domestic and otherwise – should include shading of walls and windows exposed to the sun. This could be in the form verandas, awnings, blinds, shutters and planting of climbing or other shade-giving plants. These ideally would provide shade from the summer sun but allow winter warming when the sun’s rays fall at a lower angle.
  5. Other natural cooling could include vents at high-level that draw out hot air without allowing hot air back in and which can create a cooling air flow.
  6. In some situations – such as hospitals and care homes – air conditioning may well be essential. Who will foot the bill? The taxpayer?
  7. Prisons too should be be considered for air conditioning as people confined to a small space with limited options for cooling are vulnerable.
  8. For some vulnerable groups – the old and very young, people with particular disabilities or ailments – additional provision of air conditioning at home may be necessary.  Who will foot the bill? The tax payer who might then avoid the higher cost of medical care? Should grants/ loans be means-tested?
  9. Consider providing schools and libraries with air conditioning if these can then also be used  as cool hubs for other users. Encourage community networks that can check up on vulnerable people.
  10.  Expand number of cool hubs – encourage pubs, churches, community halls and libraries to participate – provide grants to encourage this. This map shows what is currently publicly available in London – https://apps.london.gov.uk/cool-spaces/
  11.  Ensure everyone is well informed about how to cope with heat waves – public health campaign etc. The Red Cross has food advice – could this be made available as a booklet? https://www.redcross.org.uk/get-help/prepare-for-emergencies/heatwaves-uk
  12.  Install more drinking water points and encourage people to carry refillable drinking bottles.
  13.  Public health campaigns to encourage everyone to use a sunhat and/or parasol. 
  14.  Switch to double summer time so that in the summer we are getting up two hours earlier when the day is much cooler. (The clock change could take place at the May bank holiday).
  15.  Set the school day to start an hour earlier to maximise use of cooler air. This would also encourage businesses and shops to adopt earlier opening hours. 
  16.  Switch the school year to start in January so that exams can be held when the weather is cooler. Consider dividing the academic year into four terms.
  17.  Encourage adoption of an afternoon siesta to include shops and businesses – but also consider could/ would this time be of benefit to staff.
  18.  Legislate for maximum working temperatures. Legislate for regular – paid for – rest periods during hot weather.
  19.  Mandate welfare provision such as access to toilets, drinking water, cool spaces etc for all work environments including bus, lorry and delivery drivers.
  20.  Expand planting of trees in streets and parks to create more cool places. 
  21.  Expand the creation of parklets to provide cool resting places.
  22.  Encourage where practical replacement of hard surfaces and drive ways with grass or other suitable planting. Encourage generally more planting to create localised cooler microclimates – as well as supporting biodiversity.
  23.  Public health campaign to encourage active travel so as to reduce the number of cars driving or parked on the streets where they absorb and radiate heat.
  24.  Encourage shops and businesses to install awnings to provide protection from the sun in summer and rain in winter. 
  25.  Mandate that premises using air conditioning keep doors closed to conserve energy. Such premises should not be attempting to cool the whole street! A public health campaign could encourage closing doors and windows to keep the heat out. 

Any other suggestions?

How to keep cool in hot weather

26th June 2026

  1. Drink lots of fluids.
  2. Dress in loose light coloured and light weight clothes. Go bare foot (unless the ground surface is too hot).  Wear a sun hat. Use a Japanese style paper fan. (Hand held battery fans will ultimately just add to landfill problems).
  3. When temperatures outside are cooler than inside then during the day close curtains to keep the sun out whilst,  if cool enough outside (ie of it is cooler out than in), keep windows open to allow air moving through the room. You might also a bowl of water on the window sill or hang up wet towels to benefit from the cooling effect of evaporating water. When the sun sets or moves round, open the curtains to allow maximum airflow of cooler air. Open windows on different sides of the house and different floors to encourage air to move through the house. 
  4.  If the outside temperature is warmer than inside, it will be better to keep bight windows and curtains closed to keep that hot air out – consider how keeping the windows closed in winter keeps the cold out. If you have a loft or roof space you might open a window here to draw out heat that is building up in the house. Only open the windows when the temperatures drop and then open as many as possible to pull in the cooler air.
  5. Turn off unused electrical appliances, even those on sleep may be emitting extra heat into the room.
  6. Shade the outside of the window to prevent the glass from heating up and radiating heat into the room. You could use a sheet or towel as an ad hoc shade. Or place a gazebo or sun parasol to shade the window. Longer term consider fixing an awning to shade south facing windows and/or install external shutters – these will also work to keep warm air in in the winter. Erect a pergola outside and allow climbing plants to shade the window.
  7. Sit with your feet in a bowl of cold water. Keep damp flannels in the fridge for a cool wipe.
  8. Freeze a plastic bottle of water (don’t completely fill the bottle as frozen water expands)  and use it as a cold ‘hot’ water bottle. To avoid ice burns wrap in a towel before placing it on your skin. Alternatively place in your bed at night.
  9. Fill a sock with rice, secure the end and place in the freezer. Use as a cold pad or as cold ‘hot’ water bottle in your bed. 
  10. Get up early and start your day while it is still cool. Catch up on sleep later with an siesta when its hot. 
  11.  Consider using planting to cool your home – climbers, large shrubs and trees can provide useful shade, herbaceous borders can create cooler local microclimates, grass and planting – unlike paved areas – will absorb rather than radiate heat.
  12. Have you a tip to share?

Love

“Ultimately, love is the reason we do one thing and not another. What we love determines how we act.” (P139) Those this does beg the question, what do we love? The answer might be money, power or self.

As an alternative, Davison suggest we might “see love as the criterion by which are actions are judged.” (P140)  Do our actions express a God-like love?

Davison then explores an often overlooked issue – “What difference does my contribution make?”

One answer is that even that small difference is worth doing if it is the right or just thing – think of the parable of the widow’s mite. (P141)

Another is that we are in this together. (P142) My small contribution is part of our communal action and therefore part of a bigger whole. It is as communities that we best give and  receive love, and as communities that we will best make the changes we need to make to safeguard our common future. 

And again Davison reminds us of the core focus of the book (1), restraint. Love will always help us exercise restraint, and as regards our future, love will help us exercise restraint in the net zero lifestyles that we must embrace.

Hope

‘Among the virtues, the one that looks the most to the future is hope. Just as importantly, hope also looks to God. Indeed, Christians will say that they can venture great things because their confidence rests in God, not themselves.’ (P121)

Davison then considers that human endeavours are most effective where they are human in scale, reflecting the fact that humans are communal creatures, and that this is where hope best thrives. ‘St Thomas of Aquinas’, writes Davison, ‘describes hope as the entirely necessary human capacity to strive for difficult but not impossible future goods.’ (P124). This hope, says Davison connects our actions and aspirations to God and the overarching story of redemption. 

As we tackle the difficult but not impossible challenge of the climate crisis, we know that we are not doing this on our own, but with God, for creating a better future in this world is God’s desire too.

Faith

Davison introduces us to some of the theology of St Bonaventure, vis that ‘the characteristic effect of faith is to transform the intellect, of hope to transform memory, and of love to transform the will’ and that these are the three main ways in which we bear the image of God. (P108)

Faith, then, shapes how we see the world, how we act within it, and how we understand the relationship between ourselves, the world and God. Faith them motives and shapes our desire that we live so as to ensure a sustainable and equitable future for all life on earth. Davison gives us a further insight from the teaching of St Augustine of Hippo. ‘[T]he Christian should value the world, with its good things, like a bride (or, we would add,  bridegroom) values a wedding ring. Loving the ring more than the person would be weird and insulting, but so would despising the ring. The world is not God, and to value it over God would be a travesty, but it is also God’s gift, and treating it badly is it’s own kind of insult to the one who gave it.’ (p112)

I think one might add to that, the idea that a wedding ring is a sign of a covenant between the two parties.

Faith in God is inseparable from faith in God’s desire for a good Earth. Faith therefore compels us to care.

Justice

“‘What will it cost to make the climate safe?’ That is a question for mangers, engineers, economists and politicians, but [t]he ultimate question is ….’how much will it cost not to make the climate safe?’” (P83) This is where justice is the prevailing virtue, for rather than what will it cost me to act, it is what will it cost my neighbour/ my children/ future generations if I don’t act?

So in pursuing a liveable future, Davison writes: “Prudence looks ahead … and navigates the path. Courage spurs us on to overcome obstacles. Temperance checks us from being lured off course …  [And] justice is our goal”. (P83)

What then is justice? As a base, Davison suggests it is giving a person what they are due or conversely that they should not suffer harm or wrong doing without recompense. (P85). This can apply as much to a community as to an individual. Virtues are meant to make us better people so justice is also about us: justice should make is people who seek fairness for others. And that is what God made us for: “act justly and to love mercy and to walk humbly with your God.” Micah 6:8

There is no escaping the fact that as Christians we are compelled to act on climate change so that if nothing else, we can ensure justice for all our neighbours.

Temperance

If courage is the strength or virtue we need to overcome our hesitancy of acting when we would rather not, then temperance is the strength or virtue we need to overcome the temptation of doing what we know we shouldn’t do even when it seems so attractive. “If courage deals with aversion, then temperance deals with allure “ (p64)

Temperance is the virtue that helps us weigh up what is good and why is not good about the options on offer. It helps us distinguish between want and need. It helps us find the balance between too much and too little. Temperance helps to free us from false truths – more, bigger, faster, easier are not always better!

Temperance helps us exercise restraint: 

Davison reflects on the widespread practice of fasting within the Christian faith – such a during Lent. Here the practice of fasting where going without helps us to let go of distractions, enable us to focus on spiritual preparation. But Davison the reminds us that fasting for Lent may only be for 40 day where as the restraint we need to show to address climate polycrises, has to be a lifetime’s undertaking. Yet, whereas we may choose fasting in Lent that is deliberately discomforting (eg giving up chocolate), the restraint we must adopt as a complete life style change, can be such that it is pleasurable – eg having more free time for reading, eating a more tasteful diet etc. 

Davison  then draws out another analogy for us: athletes because of their love of the sport, will exercise temperance and discipline in their daily lives to ensure that they can be best athlete that they can be. Our love of God, our love of creation, will inspire such dedication in our daily lives.

Proper 7, third Sunday after Trinity

Reflection with readings below

I struggle – not I think unreasonably  – with today’s words from Matthew’s Gospel. Maybe they reflect the situation that prevailed in 1st century Christian communities.  Maybe they were struggling with division and conflict between those who believed and those who didn’t; those eager to speak out and those who preferred discretion; those who felt it was more important to survive as a community within their society and those who felt it was more important to stand apart from the prevailing society. If so, then it seems a if the writer of Matthew’s gospel wants to reassure those whose faith pits them at odds with their families, with their community, with society. 

On the other hand, it is important to consider that for some people their Christian faith – or maybe their understanding of that faith – does put them at odds with family, with friends, with work colleagues, with governments.  Only last week we saw 4 young people imprisoned because their views on the outrageous actions carried out by the State of Israel against Palestinians, put them at odds with our government. They felt that that those manufacturing arms to supply the Israeli Defence Force should be stopped where as the government did not. 

In the Church Times one can read letters and articles that highlight the differing views of Christians on the rights of transpeople, or about the conflicting views about national identity and Christian identities. 

Perhaps what we can learn from today’s gospel is the importance of listening to other people’s viewpoint (even if we don’t agree) and in seeking to understand the situations that lead to conflict, as well as the importance of trying to establish the truth. Today’s gospel also encourages to be willing to let go of long held views when these prevent us living more truthfully as followers of Jesus.

The passage from Jeremiah also makes for a challenging read. To serve God does not guarantee a life of roses. God understands that life is not always straightforward, is not always easy, and that to counter what is going awry can demand vulnerability.  It is not everyone’s vocation to be a prophet, but for those who are, it is a challenging role. Jeremiah’s words express how it can feel to present a counter story or a counter argument to the accepted way of a society. How it feels to be mocked and here’s. How it feels to be the one – apparently – out on a limb. Yet when prophets speak and act in truth for God, they can find consolation in knowing that God understands and values what they are going through.

Paul knew well from his own experience how it felt to be persecuted, to be mocked and derided. He knew how hard it is to stand in opposition to those with whom you have grown up, in opposition with those with whom you had previously shared common beliefs, and how hard it was to strike out on a different path. He also knew how hard it was to challenge – and be challenged by – your fellow believers when points of conflict arise. But I think Paul saw that leaving behind past practices, past ties, was akin to leaving behind an old self, an old body. It was as he describes in the letter to the Romans, a dying to sin. And that conversely stepping away from the old ways and previously held beliefs, to follow the new of Jesus, was – and is! – a form of rebirth. In Christ we enlivened by new life that is without compare.

A few weeks ago we heard from Matthew’s gospel, the Pharisees complaining that Jesus was mixing with tax collectors and sinners – with those they deemed as undesirables. But Jesus sees it as his mission to drink and eat – to socialise – with them. Then he reminds the Pharisees that it is the sick who need a doctor. Do the Pharisees, I wonder, pause to think whether it is the tax collectors and sinners or they, the Pharisees, who are the ones in need of a doctor?

So let’s not be distracted by today’s gospel from following the example of Jesus of mixing and socialising and talking and listening to one and all.

Jeremiah 20:7-13

O Lord, you have enticed me,
and I was enticed; 

you have overpowered me,
and you have prevailed. 

I have become a laughingstock all day long;
everyone mocks me. 

For whenever I speak, I must cry out,
I must shout, “Violence and destruction!” 

For the word of the Lord has become for me
a reproach and derision all day long.

If I say, “I will not mention him,
or speak any more in his name,” 

then within me there is something like a burning fire
shut up in my bones; 

I am weary with holding it in,
and I cannot. 

For I hear many whispering:
“Terror is all around! 

Denounce him! Let us denounce him!”
All my close friends
are watching for me to stumble. 

“Perhaps he can be enticed,
and we can prevail against him,
and take our revenge on him.”

But the Lord is with me like a dread warrior;
therefore my persecutors will stumble,
and they will not prevail. 

They will be greatly shamed,
for they will not succeed. 

Their eternal dishonour
will never be forgotten. 

O Lord of hosts, you test the righteous,
you see the heart and the mind; 

let me see your retribution upon them,
for to you I have committed my cause. 

Sing to the Lord;
praise the Lord! 

For he has delivered the life of the needy
from the hands of evildoers. 

Psalm 69: 8-20

8 Surely, for your sake have I suffered reproach, *
and shame has covered my face.

9 I have become a stranger to my own kindred, *
an alien to my mother’s children.

10 Zeal for your house has eaten me up; *
the scorn of those who scorn you has fallen upon me.

11 I humbled myself with fasting, *
but that was turned to my reproach.

12 I put on sack-cloth also, *
and became a byword among them.

13 Those who sit at the gate murmur against me, *
and the drunkards make songs about me.

14 But as for me, this is my prayer to you, *
at the time you have set, O Lord:

15 “In your great mercy, O God, *
answer me with your unfailing help.

16 Save me from the mire; do not let me sink; *
let me be rescued from those who hate me
and out of the deep waters.

17 Let not the torrent of waters wash over me,
neither let the deep swallow me up; *
do not let the Pit shut its mouth upon me.

18 Answer me, O Lord, for your love is kind; *
in your great compassion, turn to me.’

19 “Hide not your face from your servant; *
be swift and answer me, for I am in distress.

20 Draw near to me and redeem me; *
because of my enemies deliver me.

Romans 6:1b-11

Should we continue in sin in order that grace may abound? By no means! How can we who died to sin go on living in it? Do you not know that all of us who have been baptised into Christ Jesus were baptised into his death? Therefore we have been buried with him by baptism into death, so that, just as Christ was raised from the dead by the glory of the Father, so we too might walk in newness of life. 

For if we have been united with him in a death like his, we will certainly be united with him in a resurrection like his. We know that our old self was crucified with him so that the body of sin might be destroyed, and we might no longer be enslaved to sin. For whoever has died is freed from sin. But if we have died with Christ, we believe that we will also live with him. We know that Christ, being raised from the dead, will never die again; death no longer has dominion over him. The death he died, he died to sin, once for all; but the life he lives, he lives to God. So you also must consider yourselves dead to sin and alive to God in Christ Jesus.

Matthew 10:24-39

Jesus said to the twelve disciples, “A disciple is not above the teacher, nor a slave above the master; it is enough for the disciple to be like the teacher, and the slave like the master. If they have called the master of the house Beelzebul, how much more will they malign those of his household!

“So have no fear of them; for nothing is covered up that will not be uncovered, and nothing secret that will not become known. What I say to you in the dark, tell in the light; and what you hear whispered, proclaim from the housetops. Do not fear those who kill the body but cannot kill the soul; rather fear him who can destroy both soul and body in hell. Are not two sparrows sold for a penny? Yet not one of them will fall to the ground apart from your Father. And even the hairs of your head are all counted. So do not be afraid; you are of more value than many sparrows.

“Everyone therefore who acknowledges me before others, I also will acknowledge before my Father in heaven; but whoever denies me before others, I also will deny before my Father in heaven. 

“Do not think that I have come to bring peace to the earth; I have not come to bring peace, but a sword. 

For I have come to set a man against his father,
and a daughter against her mother,
and a daughter-in-law against her mother-in-law;
and one’s foes will be members of one’s own household.

Whoever loves father or mother more than me is not worthy of me; and whoever loves son or daughter more than me is not worthy of me; and whoever does not take up the cross and follow me is not worthy of me. Those who find their life will lose it, and those who lose their life for my sake will find it.”

Listening to the sounds of the world

20th June 2026

I will listen to you, LORD God, because you promise peace to those who are faithful and no longer foolish. Psalm 85:8

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.

Reading from 1 Kings 19: 11b – 13a

Now there was a great wind, so strong that it was splitting mountains and breaking rocks in pieces before the Lord, but the Lord was not in the wind; and after the wind an earthquake, but the Lord was not in the earthquake;  and after the earthquake a fire, but the Lord was not in the fire; and after the fire a sound of sheer silence. When Elijah heard it, he wrapped his face in his mantle and went out and stood at the entrance of the cave.

The day is quiet. 

It catches my attention. 

No murmur of cars, nor drone of airplanes. 

No crash or thump of builders. 


Silence – 

Silence? Are you sure?

I can hear a bird – 

no not one but two, maybe three – 

singing. 

The buzz of a passing insect. 

The wind rustling a leaf.

The slight crunch of my shoes on the ground.

The soprano voice of a child – 

Mummy, why do ….?

God, creator and companion, 

Stay my attention on the sounds of ‘silence’, 

on the sounds of life. 

Attune my heart to hear 

the unabated sound of creation, 

to sift out the raucous noise 

of the unimportant sounds.

Open my ears just enough to know your presence.

Ever mindful God, be present 

with those surrounded with the noise 

of guns and bombs. 

Bring compassion 

into the hearts of those who wage war. 

Remove greed and pride from those 

who might then make peace.

Ever mindful God, be present 

with those surrounded with the noise 

of traffic and engines.

Bless the work of those who create green spaces, 

those who bring calm to frenzied lives.

Lend strength to those who protect the environment 

and those who seek a quieter way of life.

Ever mindful God, be present 

with those who seek to tell the truth – 

however inconvenient. 

Open hearts and minds to hear your word, 

to discern your wisdom. 

Give grace to all who question, 

to all who seek to understand 

and to all who are willing to learn – 

for you the way, the truth and the life. 

Amen.

Prudence “is the virtue of being undeceived, of being in touch with reality.” (P 44)

Both authors agree that the urgency of the climate crisis is such that we can not wait for technological solutions to be innovated and/or scaled up. We need to act now with the knowledge and resources we already have – “we need to be prudent.” (P 44)

Davison explores a deeper understanding that says “to be prudent is to know what the world is like, to know what the world should be and to work out how to go from one to the other.” (P 45) This challenges us to identify realistically where the world is not as it should be – especially bearing in mind those people and places outside our immediate bubble (where I suspect we do feel everything is OK). And having been realistic in seeing the world as it really is, identifying what we can do to change it – including changing our own lifestyles – for those will be the changes that mirror the Lord’s Prayer: your kingdom come on earth as it is in heaven.

NB if you don’t feel you have time to read the book, or even if you do, you might like to watch a recording of the talk Julian Allwood gave to Green Christian.
