Is Climate Change the New Doctrine of The Catholic Church?

From THE WESTERN JOURNAL

At Castel Gandolfo last week, Pope Leo XIV managed to make global headlines—but not for preaching the gospel. Instead, he solemnly blessed a block of ice at the Raising Hope for Climate Justice conference.

The gesture, intended as a symbol of melting glaciers and a warming world, was met with laughter and disbelief. “Will this become Holy Water?” one observer quipped online. Others were blunter: the papacy, they said, has become climate theater.

The pope’s symbolism was meant to inspire. Instead, it revealed something troubling: the Vatican’s moral authority is being melted down into a prop for environmental politics. When the Bishop of Rome plays to the gallery with ice blocks and photo ops, the message is clear: faith is being repackaged to serve as a public relations tool.

This spectacle was not an isolated event. It came paired with a speech in which Pope Leo condemned those who “minimize the increasingly evident impact of rising temperatures” and derided critics who “ridicule those who speak of global warming.” It was a script that echoed Pope Francis’s 2015 encyclical Laudato Si’, which firmly planted the Roman Catholic Church in the middle of global climate activism.

Leo XIV insisted, “We will raise hope by demanding that leaders act with courage, not delay.” But these words ring less like pastoral guidance and more like political sloganeering. A shepherd’s role is to guide souls — not to issue rallying cries that could just as easily be lifted from a UN climate summit.

The blessing of ice exposed the problem most starkly. A papal blessing traditionally sanctifies elements that nourish the life of the Roman Catholic Church: water for baptism, bread and wine for the Eucharist, oil for anointing. Here, ice was not consecrated for divine purposes, but conscripted as a prop for political messaging.

That distinction matters. The sacraments draw their power from Christ, not from climate metaphors. When holy ritual is used as a stage device, it cheapens both the faith and the message. A block of ice cannot stand in for stewardship of creation, nor does blessing it advance the mission of the Roman Catholic Church.

Pope Leo also repeated the familiar claim that climate change hits the poor hardest, and that skeptics are “blaming the poor for the very thing that affects them the most.” But here again, rhetoric outruns reality. In practice, it is the poor who suffer most under the weight of climate policies themselves. High energy costs, stifled development, and curtailed opportunities are the bitter fruits of the “green” agenda. Europe’s recent energy crisis, driven by overreliance on renewables and a retreat from affordable fossil fuels, left families struggling to heat their homes. Across Africa, development is stifled by Western climate aid packages tied to restrictions that prevent industrial growth. These policies, cheered on by elites, deepen poverty rather than relieving it. Yet the pope reserves his sharpest criticism not for policymakers, but for skeptics.

This is not the first time the Roman Catholic Church has tied itself to a scientific consensus. The Galileo affair remains a cautionary tale: doctrine was entangled with prevailing science, and when that science shifted, Rome’s credibility collapsed. Today, climate models — uncertain, politicized, and often wrong — are treated as moral absolutes from the pulpit. It is a dangerous repetition of history.

Yes, the climate changes. It always has. But the leap from “some warming” to “existential crisis requiring radical global transformation” is not theology — it is ideology. The papacy should never mistake one for the other.

As a Roman Catholic, I want to be clear: I do not deny the call to stewardship of creation, nor do I reject the authority of the Roman Catholic Church in matters of faith and morals. But I cannot support the Holy See when it uses the papal office to advance politicized views on climate science. My disagreement is not with the faith but with a misguided application of it. The pope’s duty is to lead souls to Christ, not to serve as a spokesman for contested policies.

Scripture is clear: we are to care for the Earth. But stewardship is not synonymous with political posturing or theatrical stunts. Blessing blocks of ice may make headlines, but it does nothing to strengthen faith or lift the burdens of the poor.

The Roman Catholic Church’s mission is eternal salvation, not temporal activism. Its message should be timeless, not tied to the agenda of climate conferences. If Pope Leo truly wishes to raise hope, he would do better to preach than pontificate. For Roman Catholics, salvation will never be measured in tons of CO₂ — but in faith, truth, and fidelity to the gospel.

Pray for Pope Leo. He may be less of a scientific moron than Pope Francis, but he is still burdened by his ignorance. Re his role as leader of the Catholic Church, he is failing in many ways, and failure to promote sound science is one of the smallest issues.

Thank you Anthony. As a fellow Catholic, you have exactly expressed my view as well.

I wonder how much he believes this climate catastrophe nonsense and how much politics within the Church is forcing his hand to try to hold things together. In any case, whether it’s sincere error or imprudent intra-ecclesial politics, it doesn’t touch the true faith in any way.

As I have argued in previous comments, the idea that popes can make errors is not in conflict with the dogma of papal infallibility since that dogma extends only to matters of faith and morals. His teaching here is a prudential judgment.

In any case infallibility relates to confirming the faith handed down from the apostles. I don’t recall reading the parable of the hockey stick in any of the gospels!

He has to be “wrong headed” because he was cheated into “office” even more than Biden – the guy who at the age of 80 suddenly became an overwoke, open border,diversity ,tranny lover(without even knowing).

And this pope is just as “authentic” as Joes wokeness.
The USA is 10* worse than Sodom and Gomorrah.
Degeneration,perversion,corruption all over the place.
Electing someone from the USA as pope is like chosing your mother superior from a brothel or making a Pigfarmer run Mekka – impossible, but normal in a crazy world.

Just as Obama he is from Chicago (I wonder if his career was also financed by the Mafia families Pritzker and Crown) and Chicago was the place they tried to establish the scam of all scams: a Climate Wall Street = CCX.

Funny thing: He was stationed in Peru,
a country with an average altitude of a mile where you just need to walk 200 meters away from the coast to get your 2 degrees of cooling to compensate the AGW..
And despite Perus(and USA’s) endless coastline(same with Italy) and that it hasn’t changed anywhere throughout the decades he still pretends to believe in global warming.

On the other hand I shouldn’t complain too much as I said from day 1 that he is a 100% AGW imposter.
As the only chance for a guy from Sodom to become Pope is wokeness and a rigged election (and to counter Trump)

Cardinal Baronio made the statement often erroneously attributed to Galileo: “The Bible teaches us how to go to heaven, not how the heavens go.”
As a Catholic I am deeply disappointed that the leaders of the Church have become so committed to the notion that there is a climate emergency caused by human behaviour. As has been pointed out, this is a matter of prudential judgement and the Popes should have left it at that. Instead, every week my local parish bulletin contains a quotation from Laudato Si, as if that were the most important papal encycical of all time. The Scottish Catholic International Aid Fund (SCIAF) regularly sends representatives to COPs in order to get them to commit further to abandon fossil fuels even though by doing so they are condemning millions of people to living in continued poverty. One can but pray that the Church abandons this nonsense as soon as possible.

I’m not surprised by this at all. The Catholic Church is a worldly cult to begin with. The ugly history of this Cult and it’s heresy, of placing themselves, and Mary, in-between man & Jesus, is all anyone needs to know, goes directly against what Jesus taught. Most Catholics have never read, and understood the Bible for themselves. For the curious, I recommend reading the Bible, and Constantine’s Sword, for a historical account of several nasty centuries of the Catholic Church, the rest of which, were the same. The Emperor Constantine co-opted the Catholic Church, merging the State & Religion. Before the Protestant Reformation, people couldn’t even have a Bible to read on their own. Which meant the church could just dictate whatever it wanted to the masses. In essence, Catholics believe in a Works Salvation, not a Salvation of Grace.

I see the vitriol, but I don’t see the lies.
It is true that the Catholic Church put the Saints and Mary between people and Jesus. Before we were married, I took my wife to the church I had been attending. She told me afterword that it seem sacrilegious to her, to pray directly to Jesus. She been taught that you were supposed to pray to the Saints and they would carry your prayers to Jesus. In her words, when you have a problem, you go to the secretary, not directly to the boss.

Also, the Catholic Church was opposed to having the Bible written in the local languages, they kept it in Latin for many centuries. It wasn’t until a bit over a century ago that the Catholic Church changed it’s position on this. A number of really conservative churches still conduct the Mass in Latin.

I bought my wife her first Bible, she had never read it herself or been encouraged to do so.

That is full of Protestant lies. (By which I mean lies that are often put forward by Protestants.)
In the Bible we read that Mary asked Jesus to do something about the lack of wine at the marriage feast at Cana. Catholics simply ask Mary to ask Jesus to do something on our behalf.
Catholics probably hear more of the Bible read in their churches at Mass in the course of a year than the average Protestant. It is just a lie to say that before the Protestant Reformation people were forbidden from having a Bible to read on their own. What prevented most people from having their own Bible was the huge cost of producing a Bible and the fact that most people were illiterate. After the invention of the printing press lots of people were able to buy a Bible. There were also translations of the Bible into the vernacular long before the Protestant Reformation.
As to Constantine merging the state and religion, that is just a load of hooey.
These were all myths promoted by Protestants to justify their departure from the Catholic Church. Just like the many myths associated with the Inquisition.

I can’t remember exactly how it was worded, but one of the leaked Podesta/Steyer Obama/Gore era emails boasted that they’d got their man inside the Vatican to influence the climate rhetoric.

But it’s not just the Catholic church. Go to a Methodist Church these days and the sermon will frequently be filled with climate alarmism/lecturing.

And the BBC’s religious messages and thoughts for the day from Christian churchmen, more often than not, contain heavy climate notes regardless of denomination.

I guess they think that by latching onto the new climate religion, they might somehow stay relevant.

I was raised Catholic but now go to a Methodist church whose clergy is liberal but the congregation is split. The one woke topic the clergy seems to avoid is climate change. Perhaps they realize how political and divisive this topic is. Perhaps they also realize many climate solutions serve the affluent vs those struggling.
When Christian religion serves the needs of the political powerful its moral authority is diminished. I also think there is an insecurity in the west who have lost their religion from which much of their cultural values sprung from. Economically the west is barely growing and industrial production has moved to Asia which has accelerated due to misguided climate policy. And regions of the world now growing economically are not Christian countries, making the pope’s stunt even more irrelevant.

“In practice, it is the poor who suffer most under the weight of climate policies themselves.”

Yes, it is the poor who suffer most when fossil-fuel use is denied them. In fact, limiting fossil fuels to combat climate change goes against Pope Francis’s 2015 encyclical. He repeats the advice of previous Popes when he says that the resources of our planet (the fruits of the Earth) are a gift from God and belong to everyone and should be shared equally with the poor. Don’t fossil fuels come from the Earth? Are they not a gift from God that should be shared? Who has the right to tell the poor or anyone else that these gifts from God are off limits? Does the Pope have that right?

October 13, 2025 5:30 am

I’ll throw out a different perspective for consideration, as a geoscientist & a person of the Christian faith :

The general trend in CO2 concentration over geologic time has been downwards , being sequestered by a number of geological processes but primarily organic matter extraction from the air & preservation in rocks (oil, gas, coal) and more importantly by volume, carbonate rock formation.

We know the minimum CO2 concentrations needed for plants to survive… and plants need to survive so animals & humans can survive. As most know here, CO2 is essential to life.

On a relative basis, we are dangerously close to the low end of minimum CO2 needed for life as we know it :
Geologic maximum (in Paleozoic) : 3,000 – 9,000 PPM
Minimum for plant survival : 150 PPM
Pre-industrial age concentration : 280 PPM (and as low as 180 PPM during the most recent glaciation ~)

If we use ~6000 PPM (midway between the Paleozoic range) and where we were at pre-industrial age:

(280-150)/ (6000-150) = ~2.2%
…. or we had sequestered ~ 98% of our CO2 needed for life & only had ~2% left to keep life on our planet going. The geologic processes that naturally sequester CO2 have not stopped. The next cycle of glaciation (we are currently just in an inter-glacial) which will come at some point , could drop us below our critical 150 PPM and then it is game set & match for life on Earth.

Our current concentration is ~422 PPM & by the same math again, we are only up to ~4.6% … very much on the low end of the range & still close to the minimums to sustain life.

So here’s the different perspective: Hydrocarbons have demonstrably and vastly improved the overall quality of & quantity of our lives as humans (think about our quality of life & length of life (on average) now versus the 1800s) , as well as moving us away from dangerously low levels of CO2 to sustain all life. It is absolutely a double-blessing !

I think it could be argued that the endowment of hydrocarbons we have may be the greatest blessing we have … a divine blessing perhaps some would say & one that we should both give thanks for and use to lift all people up to better lives, not suppress. Smart use of hydrocarbons is the best stewardship for our planet and its people.

0.83 g of CO2. If a plant takes in one cubic meter of this air there will be produced 5 g of glucose. This why it takes so long to produce food.

More importantly, this small amount of CO2 can’t cause any warming of air as claimed by the IPCC.

Wow, that’s really stupid and inappropriate for a Pope.

‘No food, no business’: Kenyan women reveal hidden links between climate change and mental health
Now that he’s fixed Gaza and they’re free at last to build their Mediterranean resort.

I went to the Western Journal, and it detected my ad blocker and ask for a money donation. No thank you. So I came right back to WUWT.

I go to many websites and many of them are begging for money especially the environmental NGO’s

The last several popes have exhibited Marxist tendencies. Yes, they’ve even gone there.
