The world is failing to curb carbon, and we may be close to a scorched earth tipping point
Idea
Donald Trump is America’s first president to scream “drill, baby, drill.” And the Independence Day parade in Washington over the weekend became the first parade in 250 years to be canceled due to intense heat.
On the same day, Iran, which showed its oil power to force the world economy by closing the Strait of Hormuz, installed 6000 sprinkler systems to cool the crowd at the funeral of Ayatollah Ali Khamenei.
For the first time, World Cup matches are being stopped for mandatory hydration breaks in each match to protect player health from extreme heat. While health regulations in Paris have been relaxed to allow people to swim in the River Seine, French stores are reporting chalk leaks as people are submerged. They smear their windows white to reflect sunlight.
Of course, it wasn’t enough to protect everyone. French authorities are reporting a preliminary heat death toll of 2,025 people per week from June 22, the peak of the record heatwave; This number is approximately 30 percent more than in the corresponding week last year.
Overall, heat wave Killed more than 4000 people In Western Europe, it is based on preliminary national calculations. Belgian authorities said they have seen the highest one-day death toll since the first wave of the Covid-19 epidemic.
The years 2023-2025 were the three hottest years on record. The world is failing to rein in carbon. Because collective solutions have failed, people who can afford to buy private protection are doing what they can. There is something working on the air conditioner. “A/C stocks become next hot bet as Europe weakens” made headlines in London Finance Times two weeks ago.
Taking it a step further, some of the people who reap the biggest profits from the carbon-pumping economy are protecting themselves with the trendy profit room indulged by billionaires.
“A snow room is more or less the opposite of a sauna.” like New York Times describes it. “It’s a cave-like space of ice and snow. In some, white flakes slowly descend from the ceiling, creating the feeling of being inside a snow globe.” Prices start at US$130,000 ($187,200).
Petrochemical billionaire Mukesh Ambani has installed one in his skyscraper home in Mumbai, the newspaper reported. Saudi Crown Prince Mohammed bin Salman has one on his superyacht.
snow room manufacturer, Tyler Slater of Spa Butler In Texas, he says, “We can basically produce any fantasy you want. Think of it as snowy Disneyland.”
But while you can visit Disneyland, you can’t live there. Climate activist George Monbiot calls the “billionaire brain” a pathology. One symptom, he says, is an inability to see beyond short-term gain: “They will plunder the planet for a few more rocks on a mountain of unnecessary wealth.”
Friederike Otto, professor of climate science at Imperial College London, says: “Climate change is here, it is already affecting the things we enjoy in our daily lives, and it will continue to get worse the longer we prolong the inevitable transition to net zero emissions.”
Yes, but how long will it take? Today, hopes for progress are threatened by the global fashion for electricity-guzzling data centers. The Australian government requires backers to supply renewable energy to their projects, but other countries are not as responsive.
It is too early to despair about humanity’s ability to keep warming within the Paris Agreement’s 1.5 degree limit. Although The global average for 2024 was 1.55 degrees The fact that it is already above the pre-industrial average is not enough to make the goal unachievable. Because Paris Agreement temperatures are measured as 20-year moving averages.
UN Environment Program tells us “It remains technically possible to reach a 1.5 degree Celsius pathway, where solar energy, wind and forests hold real promise for far-reaching and rapid emissions cuts.”
But he says countries need to set more ambitious national targets. So we can get there, but how long will it take? So, in the meantime, will we resort to tipping points that will make warming irreversible?
Scientists identify multiple potential tipping points. One of these is the focus of minds, especially in Europe. Atlantic Meridional Overturning Circulationor AMOC, is a giant system that circulates warm air from the equator to Europe.
“This is why Europe, located at the same latitudes, has a milder climate than the Americas,” explains Dr Trish Lavery, from the ANU’s National Security College Futures Council.
“More and more models show it is slowing down. There is debate about whether it will slow down gradually or stop suddenly. If it stops suddenly, Europe could be up to 10 degrees Celsius colder in the winter. This poses an existential threat to Europe.”
Icelandic government Determined AMOC’s collapse An existential risk in November is the launch of official planning for food and energy supplies in worst-case scenarios.
“This has kicked off a fair amount of funding and interest in Europe,” says Lavery, a former OECD strategic foresight consultant. “There would be no nice little pastures where the little fluffy sheep would graze; some areas would be covered with ice.”
a paper published in April He suggests that AMOC closure is possible by mid-century – sooner than thought.
To save time, scientists and governments are increasingly interested in projects that can postpone such serious events. “That’s why we have the world’s largest geoengineering project outside of Southern Cross University on the Great Barrier Reef,” says Lavery.
“It may sound like science fiction, but ‘sea cloud shines‘ is being seriously considered as a way to protect parts of the ocean from extreme heat.
The researchers spray seawater from a ship-mounted water cannon, creating clouds that reflect sunlight back into the sky. It works. The focus now is on how to achieve maximum effectiveness.
“Scientists think the return of coral reefs is one of the first possible tipping points,” says Lavery. “Reefs are important for protecting coasts from storm waves, protecting fish habitats, and protecting shorelines from erosion.”
Another, more striking idea: “solar radiation modification“It is intended that large numbers of aircraft or unmanned aerial vehicles will release sulfur dioxide into the stratosphere, forming clouds and reflecting sunlight towards space. This is still at the theoretical stage, but a US-Israeli based start-up called Stardust already has patents.
“It’s important to remember that these don’t solve the problem,” says Lavery, who is working on potential governance mechanisms for how such projects could be managed. “It just provides a band-aid to buy us some time to do the hard work of mitigating climate change.”
Drill, baby, drill? Without more global political will, we could be drilling ourselves to death.
