Fresh water is essential for life, but are we using it wisely?

“A new analysis of freshwater resources across the globe shows that human activity has pushed variation in the planet’s freshwater cycle well outside of its pre-industrial range. The study shows that the updated planetary boundary for freshwater change was surpassed by the mid-twentieth century. In other words, for the past century, humans have been pushing the Earth’s freshwater system far beyond the stable conditions that prevailed before industrialisation.” (1)

We are seeing more extreme wet and more extreme dry conditions across the globe. Ingo Fetzer at the Stockholm Resilience Centre notes: “Water extremes, such as droughts and flooding, can have significant impacts on ecosystems and biodiversity that function are essential for human societies. However, human activities, including agriculture, urbanisation, and climate change, influence the water cycle and exacerbate extreme events. By understanding and mitigating these factors, we can work to protect and preserve our planet’s vital water resources and maintain biodiversity.” (1)

What is AMOC?

AMOC, the Atlantic Meridional Overturning Circulation, is a system of ocean currents that help distribute warm water around the world. (1)

I wrote about this last month – https://greentau.org/2025/11/18/counting-on-189/ – but want to recommend Professor Tim Lenton’s address at the National Emergency Briefing which illustrates vividly the impact if AMOC fails: https://youtu.be/tmd6MDiJmQU?si=RcnuJIDqMeJHirD5

Research, which is still on going, suggests that the topping point which will make the collapse of AMOC inevitable could be passed in the next few decades – but the resulting collapse of the system might take another 50-100 years to happen. Even keeping the global temperature rise to the 1.5C Paris target is now predicted to carry a 10-25% risk of reaching this tipping point before the end of the century. It is a risk we cannot afford to take given the impact it will have on the viability of human life – even if that will not effect us now, it will effect future generations, our children and our children’s children.

Third Sunday of Advent

14th December 2025

Reflection with readings below

Advent is the season when we prepare for the coming of Jesus – of his coming as both a frail human baby and as the Word that establishes the reign of God here on Earth. Prophets such as Isaiah gave their people – and us – a vision of what that world order would look like. It is one of beauty and flourishing, of abundance, of healing and restoration. Who wouldn’t want to love in such a world? Why then is it that 2000 years after the birth of Jesus we still seem stuck in a world order that doesn’t protect beauty, that doesn’t enable everyone to flourish, that allows a minority to have more than enough whilst others go without, that rations healing according to wealth or advantage, that is racing towards planetary destruction rather than restoration?

Somehow we are failing to live according to the rule, the way of life, that God intends for us. It was Bernard Shaw who famously said “Christianity might be a good thing if anyone ever tried it.”

Today’s canticle is the Magnificat, the Song of Mary, which is also prophetic. What Mary proclaims is not the state of the world as it was in her day, but how it could – would – become in the day of her son, God’s son. And it is prophetic in telling how that future will come into place – and it is a way that is radical, turning the accepted order upside down!

It is a song that openly challenges the maintenance of the status quo. It is a song that openly asserts that those who are rich are going to have to fore sake most of their wealth; it is a song that asserts that those with power are going to have to vacate their high positions and enable a widespread sharing of power; it is a song that challenges those who think they know all the answers, who think they have everything under their control.

I wonder if we are ready for such a revolution? How would we feel if the rich were asked to give up their wealth? Or if those with power were asked to share it? How would we feel if those who live in comfort were asked to share the life experiences of the poor? Maybe these are the situations we are expected to ponder on and prepare for during Advent?

This last week the group Take Back Power tipped bags of manure out under the Christmas tree at the Ritz hotel in a protest aimed at highlighting the wealth inequality that exists in the UK. The group is calling in the government to establish a “permanent House of the People- a citizen’s assembly chosen by democratic lottery, that has the power to tax extreme wealth and fix Britain.”

Later the group carried out another action at the Tower of London, splashing apple and crumble and custard over the display case containing the Crown Jewels. One of the protestors said “Our country is crumbling before our eyes. We have homeless people dying on the very streets that King Charles passed on his way to the coronation, whilst there are more empty homes than unhoused people in this country. It’s time the ultra-rich pay their fair share.”

If such tactics revolt us, how would we go about bringing in the changes that the Magnificat celebrates?

Today’s gospel tells us that Jesus understood his coming onto the human stage as the messiah, would be apparent through the transformation his ministry wrought. Is his ministry still being carried on by us? Are we as Christians – as Christ Followers – bringing about a visible change in the order of things? Could a modern day bystander go and tell John that “the blind receive their sight, the lame walk, the lepers are cleansed, the deaf hear, the dead are raised, and the poor have good news brought to them. And blessed is anyone who takes no offence at me.”?

I think we are as Christians beholden to take a stand, to call our injustice and inequality, and to heal and to make good all that has been inured and destroyed by the world’s greed. We may have to be patient – and persistent – in this. But equally we should draw strength and hope from the knowledge that we are not alone, for even as we wait for Jesus, he is already alongside us.

Isaiah 35:1-10

The wilderness and the dry land shall be glad,
the desert shall rejoice and blossom;

like the crocus it shall blossom abundantly,
and rejoice with joy and singing.

The glory of Lebanon shall be given to it,
the majesty of Carmel and Sharon.

They shall see the glory of the Lord,
the majesty of our God.

Strengthen the weak hands,
and make firm the feeble knees.

Say to those who are of a fearful heart,
“Be strong, do not fear!

Here is your God.
He will come with vengeance,

with terrible recompense.
He will come and save you.”

Then the eyes of the blind shall be opened,
and the ears of the deaf unstopped;

then the lame shall leap like a deer,
and the tongue of the speechless sing for joy.

For waters shall break forth in the wilderness,
and streams in the desert;

the burning sand shall become a pool,
and the thirsty ground springs of water;

the haunt of jackals shall become a swamp,
the grass shall become reeds and rushes.

A highway shall be there,
and it shall be called the Holy Way;

the unclean shall not travel on it,
but it shall be for God’s people; no traveler, not even fools, shall go astray.

No lion shall be there,
nor shall any ravenous beast come up on it;

they shall not be found there,
but the redeemed shall walk there.

And the ransomed of the Lord shall return,
and come to Zion with singing;

everlasting joy shall be upon their heads;
they shall obtain joy and gladness,
and sorrow and sighing shall flee away.

The Song of Mary Magnificat

My soul proclaims the greatness of the Lord,

my spirit rejoices in God my Saviour; *
for he has looked with favour on his lowly servant.

From this day all generations will call me blessed: *
the Almighty has done great things for me, and holy is his Name.

He has mercy on those who fear him *
in every generation.

He has shown the strength of his arm, *
he has scattered the proud in their conceit.

He has cast down the mighty from their thrones, *
and has lifted up the lowly.

He has filled the hungry with good things, *
and the rich he has sent away empty.

He has come to the help of his servant Israel, *
for he has remembered his promise of mercy,

The promise he made to our fathers, *
to Abraham and his children for ever.

Glory to the Father, and to the Son, and to the Holy Spirit: *
as it was in the beginning, is now, and will be for ever. Amen.

James 5:7-10

Be patient, therefore, beloved, until the coming of the Lord. The farmer waits for the precious crop from the earth, being patient with it until it receives the early and the late rains. You also must be patient. Strengthen your hearts, for the coming of the Lord is near. Beloved, do not grumble against one another, so that you may not be judged. See, the Judge is standing at the doors! As an example of suffering and patience, beloved, take the prophets who spoke in the name of the Lord.

Matthew 11:2-11

When John heard in prison what the Messiah was doing, he sent word by his disciples and said to him, “Are you the one who is to come, or are we to wait for another?” Jesus answered them, “Go and tell John what you hear and see: the blind receive their sight, the lame walk, the lepers are cleansed, the deaf hear, the dead are raised, and the poor have good news brought to them. And blessed is anyone who takes no offence at me.”

As they went away, Jesus began to speak to the crowds about John: “What did you go out into the wilderness to look at? A reed shaken by the wind? What then did you go out to see? Someone dressed in soft robes? Look, those who wear soft robes are in royal palaces. What then did you go out to see? A prophet? Yes, I tell you, and more than a prophet. This is the one about whom it is written,

‘See, I am sending my messenger ahead of you,
who will prepare your way before you.’

“Truly I tell you, among those born of women no one has arisen greater than John the Baptist; yet the least in the kingdom of heaven is greater than he.”

Advent – for those who work and give

13th December 2025

Those who sow in tears shall reap with joyful shouting.

He who goes to and fro weeping, carrying his bag of seed,

Shall indeed come again with a shout of joy, bringing his sheaves with him. Psalm 126:5-6

In Scandinavia a sheaf of wheat or other grains is saved and put out at Christmas for the birds. If lots of birds come, it is said to presage a good harvest. Maybe it is a reminder that generosity is frequently reciprocal.

A reading from Deuteronomy 24:10-21

When you reap your harvest in your field and have forgotten a sheaf in the field, you shall not go back to get it; it shall be for the alien, for the orphan, and for the widow, in order that the Lord your God may bless you in all the work of your hands. When you beat your olive tree, you shall not go over the boughs again; it shall be for the alien, for the orphan, and for the widow. “When you gather the grapes of your vineyard, you shall not go over it again; it shall be for the alien, for the orphan, and for the widow.

As we prepare for Christmas amidst a rush to buy all that we want and more, let us pray for those from whose labour we gain:

We pray for shop staff and shelf stackers, warehouse workers and delivery drivers:

May their work be rewarding and well rewarded.

We pray for factory hands and machinists, for assemblers and packers:

May their labour be rewarded, their safety ensured.

We pray for farmers and growers, labourers and pickers:

May the fruits of their work be savoured and not be wasted.

We pray for the soil and the water table:

May what is extracted be replenished, may their good health be sustained.

We pray for agricultural live stock – birds, animals and fish:

May they be raised with love and respect and, at their life’s end, with dignity and care.

May we as consumers, always show out thanks and respect for the work of others.

May we be measured in what we buy,

may we be conscientious in caring for what we have,

and may we be generous in passing forward all that we can share.

Amen.

Go forth into the world in peace.

Be of good courage.

Hold fast that which is good.

Render to no one evil for evil.

Strengthen the fainthearted.

Support the weak.

Help the afflicted.

Show love to everyone.

Love and serve the Lord,

rejoicing in the power of the Holy Spirit;

and may the blessing of almighty God,

the Father, the Son, and the Holy Spirit,

be with us all.

Amen.

Can the acidification of the oceans be reversed? This from Biology Insights

“Reversing ocean acidification involves both natural and engineered approaches. The Earth has self-regulating mechanisms, such as the dissolution of calcium carbonate sediments on the ocean floor and the weathering of rocks on land. These processes release alkaline materials that neutralise acidity, but they operate over thousands of years and are too slow to counteract the current rapid changes.

“Scientists are exploring geoengineering techniques to accelerate this process. One proposal is ocean alkalinity enhancement, which adds alkaline substances like ground olivine or lime to seawater to increase its pH. This method seeks to speed up the natural weathering process to neutralise excess acidity.

“Other methods are more technologically intensive, such as electrochemical approaches that remove acidity directly from seawater. These systems would use electricity to manage ions and reduce acidity, but they face challenges of scale, cost, and energy requirements. The potential for unintended ecological side effects from these engineered solutions is not yet fully understood.” (1)

It is hard to imagine how either the geo engineering or the electrochemical solutions can work at scale. Ditto for proposals that carbon dioxide could be removed from the oceans and stored underground using carbon capture technology.

More promising are projects that focus on planting seaweeds such as kelp and sea grass which as they grow absorb carbon dioxide from the water. (2) At the same time such projects improve marine biodiversity, and indeed are often established as part of Marine Protected Areas. These project are often simply restoring ecosystems that have been degraded by human exploitation. Nevertheless even plants such as seagrass can struggle as temperatures rise and as ecosystems become more unstable. (3)

Therefore the most important way of protecting our oceans is to to reduce significantly and at speed the amount of carbon dioxide that we emit.

What is a tipping point?

From the Met Office “In the context of climate science, a tipping point refers to a critical threshold in the earth’s system or related processes which, if passed, can cause sudden, dramatic or even irreversible changes to some of the earth’s largest systems, such as the Antarctic ice sheet or the Amazon rainforest.” (1)

And from the Natural History Museum: “Large areas of the world could soon become unrecognisable if global temperatures continue to rise. From the loss of coral reefs to the shutdown of major ocean currents, shifts in Earth’s climate and ecosystems will have untold consequences for billions of people across the world.” (2)

Tim Lennon, head of the Global Systems Institute at Exeter University p, spoke very eloquently on this issue at the recent National Emergency Briefing. You can see a recording here – https://youtu.be/tmd6MDiJmQU?si=goRIfzf8AhiriESi

Tipping points also work in the opposite direction. Just last year the last coal fired power station closed ahead of schedule as policies that encouraged the phasing out of coal reached that critical tipping point. Similar tipping points can also be seen in the cost fall and expansion of wind farms, solars panels and electric vehicles.

When planetary boundaries are once crossed, it is still possible to reverse the situation and restore the balance of the Earth’s systems. However the effect of crossing a planetary boundary may irreversibly impact delicate parts of the Earth’s ecosystems such as coral reefs.

These reefs are important because:-

They protect shorelines from strong ocean currents and prevent coastal erosion
They provide sheltered waters for many species of sea life.
They filter polluted water ensuring clean water for marine life and clean beaches
They sustain local fishing based communities and especially those located on low-lying islands
They absorb carbon dioxide

Coral reefs are being damaged by the acidification of the oceans – the depletion of calcium in the structure weakens them. They are also damaged by rising ocean temperatures which stress the corals causing them to expel the symbiotic algae that enable them to feed and which give them their distinctive colours – this is called coral bleaching. (1)

The multiple causes of damage to the world’s coral reefs has destroyed such a proportion that their future is now jeopardised. These reefs are loss of coral reefs on this scale means that we have passed one of the Earth’s systems tipping points. (2)

In the Caribbean, coral reefs have decreased by 48% since 1980. (3)

Ocean health: acidification

One of the nine planetary boundaries is ocean acidification. If the oceans become too acidic it endangers marine life and therefore the lives of the rest of us who are dependent on healthy oceans.

The 2025 Planetary Health Check showed that this planetary boundary has been breached: since the start of the industrial era, the oceans’ acidity has increased by 30-40% destabilising this important Earth systems. (1)

What is ocean acidification?

“For millions of years, the ocean has acted as Earth’s carbon sponge, quietly absorbing carbon dioxide (CO₂) from the air. But that natural partnership has turned toxic in the age of fossil fuels.

“As humanity has pumped unprecedented levels of CO₂ into the atmosphere, the oceans have taken in more and more of it—now absorbing roughly a quarter of all carbon emissions. But this uptake comes at a cost. When carbon dioxide dissolves in seawater, it undergoes a chemical transformation, forming carbonic acid. That acidification strips the ocean of carbonate ions—essential building blocks for creatures like corals, clams, and countless shell-forming organisms.

“As their calcium carbonate shells thin and weaken, so too do the coral reefs and underwater habitats they support. A weakened foundation means collapsing ecosystems—once-thriving marine gardens reduced to skeletal remains.” (2)

Second Sunday of Advent

7th December 2025

Reflection with readings below

This week saplings that have been grown from seeds collected from the sycamore gap tree after it was rudely felled, have been distributed around the country. Places chosen to receive these symbols of new life have included the Alder Hey Children’s Hospital, the Woodcraft Folk’s youth campsite, the West End Women and Girls Centre in Newcastle, the Treetops Hospice, Rhiwbina Primary School, the Goan Welfare Society, and Thames Valley Police HQ. The constituent parts of a good society are varied and diverse.

Today’s reading from Isaiah also talks about a new shoot – a sign of new growth, of life springing up a new. This shoot Isaiah foretells, will create a new era, a new society where life will flourish. This new will be shaped by justice, equity, peace and harmony. Who wouldn’t want such a future for them and their children and their children’s children?

This last week has seen two different aspects of the climate crisis. One was the National Emergency Briefing held in London when ten top scientists and other experts addressed an audience of MPs (sadly only 80 turned up), peers, faith leaders, members of the press and others. Over the three hours concise arguments were presented as to why the government and those in authority should be paying serious attention to the emergency we are facing and to address the crisis with the same urgency and comprehensive engagement that was used during the Second World War. For anyone wanting to hear what was said, a full recording of the morning is available on YouTube.

The other were the horrendous floods and mudslides in Indonesia, Thailand, and Sri Lanka that have engulfed so many communities, washing away so many homes and livelihoods and depriving over 1300 people of their lives. This and similar highly destructive storms in the preceding weeks that affected the Philippines, Jamaica, Haiti and Cuba, have all been intensified by climate change.

Whether it is here in the UK or in the tropical parts of the world, we need to rebuild and reshape the infrastructure of our lives and economies. We need to build for greater resilience and we need to dismantle our dependency on oil and gas. We need to ensure strong caring communities. We need to ensure economic justice and equity. We need to restore harmony with the Earth, living sustainably within its natural limits.

We need to hear afresh the words of John the Baptist, “Prepare the way of the Lord!”

Isaiah 11:1-10

A shoot shall come out from the stump of Jesse,
and a branch shall grow out of his roots.

The spirit of the Lord shall rest on him,
the spirit of wisdom and understanding,
the spirit of counsel and might,
the spirit of knowledge and the fear of the Lord.

His delight shall be in the fear of the Lord.

He shall not judge by what his eyes see,
or decide by what his ears hear;

but with righteousness he shall judge the poor,
and decide with equity for the meek of the earth;

he shall strike the earth with the rod of his mouth,
and with the breath of his lips he shall kill the wicked.

Righteousness shall be the belt around his waist,
and faithfulness the belt around his loins.

The wolf shall live with the lamb,
the leopard shall lie down with the kid,

the calf and the lion and the fatling together,
and a little child shall lead them.

The cow and the bear shall graze,
their young shall lie down together; and the lion shall eat straw like the
ox.

The nursing child shall play over the hole of the asp,
and the weaned child shall put its hand on the adder’s den.

They will not hurt or destroy
on all my holy mountain;

for the earth will be full of the knowledge of the Lord
as the waters cover the sea.

On that day the root of Jesse shall stand as a signal to the peoples; the nations shall inquire of him, and his dwelling shall be glorious.

Psalm 72:1-7, 18-19

1 Give the King your justice, O God, *
and your righteousness to the King’s Son;

2 That he may rule your people righteously *
and the poor with justice;

3 That the mountains may bring prosperity to the people, *
and the little hills bring righteousness.

4 He shall defend the needy among the people; *
he shall rescue the poor and crush the oppressor.

5 He shall live as long as the sun and moon endure, *
from one generation to another.

6 He shall come down like rain upon the mown field, *
like showers that water the earth.

7 In his time shall the righteous flourish; *
there shall be abundance of peace till the moon shall be no more.

18 Blessed be the Lord God, the God of Israel, *
who alone does wondrous deeds!

19 And blessed be his glorious Name for ever! *
and may all the earth be filled with his glory.
Amen. Amen.

Romans 15:4-13

Whatever was written in former days was written for our instruction, so that by steadfastness and by the encouragement of the scriptures we might have hope. May the God of steadfastness and encouragement grant you to live in harmony with one another, in accordance with Christ Jesus, so that together you may with one voice glorify the God and Father of our Lord Jesus Christ.

Welcome one another, therefore, just as Christ has welcomed you, for the glory of God. For I tell you that Christ has become a servant of the circumcised on behalf of the truth of God in order that he might confirm the promises given to the patriarchs, and in order that the Gentiles might glorify God for his mercy. As it is written,

“Therefore I will confess you among the Gentiles,
and sing praises to your name”;

and again he says,

“Rejoice, O Gentiles, with his people”;

and again,

“Praise the Lord, all you Gentiles,
and let all the peoples praise him”;

and again Isaiah says,

“The root of Jesse shall come,
the one who rises to rule the Gentiles;
in him the Gentiles shall hope.”

May the God of hope fill you with all joy and peace in believing, so that you may abound in hope by the power of the Holy Spirit.

Matthew 3:1-12

In those days John the Baptist appeared in the wilderness of Judea, proclaiming, “Repent, for the kingdom of heaven has come near.” This is the one of whom the prophet Isaiah spoke when he said,

“The voice of one crying out in the wilderness:
‘Prepare the way of the Lord,
make his paths straight.’”

Now John wore clothing of camel’s hair with a leather belt around his waist, and his food was locusts and wild honey. Then the people of Jerusalem and all Judea were going out to him, and all the region along the Jordan, and they were baptised by him in the river Jordan, confessing their sins.

But when he saw many Pharisees and Sadducees coming for baptism, he said to them, “You brood of vipers! Who warned you to flee from the wrath to come? Bear fruit worthy of repentance. Do not presume to say to yourselves, ‘We have Abraham as our ancestor’; for I tell you, God is able from these stones to raise up children to Abraham. Even now the ax is lying at the root of the trees; every tree therefore that does not bear good fruit is cut down and thrown into the fire.

“I baptise you with water for repentance, but one who is more powerful than I is coming after me; I am not worthy to carry his sandals. He will baptise you with the Holy Spirit and fire. His winnowing fork is in his hand, and he will clear his threshing floor and will gather his wheat into the granary; but the chaff he will burn with unquenchable fire.”

Given that humanity has exceeded the safe planetary boundaries with respect to nitrogen and phosphorus flows, what can be done to restore a safe balance? Part of the answer lies in changing the food system – how and what food is produced and how it is distributed. Producing less meat would require less land to be dedicated to growing animal feed – both grass and grain – substantially reducing the need for nitrogen and phosphorus rich fertilisers. At the same time adapting agricultural practices such that less fertiliser is needed to grow crops, and where it is used, to ensure limited run-off onto the soil and water. And furthermore reducing food waste at all stages between field and plate.

Adopting worldwide the Eat-Lancet planetary health diet would go along way to achieving this. Will governments implement this and ensure that farmers are helped financially to make the transition?
