Giving Thanks on an Endangered Earth
So many of us are now searching for a bridge to the world we need. I’m thankful that we’re searching together and for the possibilities we may find.
Nov 27, 2025
The days grow dark here in the North as the year winds down. Friends slowly return from COP30 in Brazil, the frontline of the fight for our climate future, with far too little won. There’s a weight to the air. It’s an age of global polycrisis, an era of authoritarian upsurge, a time of anger, grief, and overwhelm, nesting dolls of troubled times, from the planetary to the personal. And in the US, it’s Thanksgiving, a time when we are meant to gather to show gratitude for the things we’ve been given.
It’s a complicated proposition, giving thanks; it has always looked very different depending on who and where you are in this country. Because what have we been given and by whom? What have we taken and from whom? What is being taken today and who are the takers?
And it grows more complicated each year, giving thanks, as so many of us whose lives are materially abundant increasingly see that abundance less as a blessing and more as our birthright and a legacy to maintain. When in reality, modern materialist lifestyles were always the brittle pretense of an era of extraction that is hollowing out the Earth and our space to be safe upon it—and is starting to crack.
And this year, with cracks appearing everywhere—in our climate, our politics, our communities, our bodies and minds, our very sense of reality—it is profoundly complicated, giving thanks. This era of capitalist extraction and detached materialism has belched up such historic, geopolitical hairballs as Donald Trump presiding over the world’s richest nation for a second time and promptly pulling us out of the Paris Climate Agreement; such inexcusable own goals as global carbon emissions hitting a new record high in 2025; and such multigenerational tragedies as the vital, life-supporting 1.5°C climate target being all but certified dead. (We can overshoot and return to 1.5°C but we’re making this task harder.)
No one knows where this is going—why can’t it be somewhere beautiful?
This follows a decade of urgent talk about the all-important “2030 deadline” for deeply reducing emissions to achieve this target—“we have just 10 years to avoid catastrophic climate change”, wait, “just 5 years”, wait… This was a message that children around the world picked up and shouted, demanding to be heard. But this year, the adults have gone quiet. The deadline will be missed.
So, it’s a complicated thanks. If I consider what really matters to me, each of those things is under some kind of assault. And my thanks is suffused with grief and anger.
But gratitude is powerful. It’s both something we offer up and, when we mean it, it’s a gift we give ourselves that can help us to hold grief, move anger, and bring us into right relation with what is.
So here are things I’m thankful for.
I’m thankful for the food that will be on the table. I’m thankful for the hands that harvested it. I’m thankful for everyday people in cities across the nation, defending our immigrant friends and neighbors from this administration’s inhumanity.
I’m thankful for the defenders of science, justice, and truth, the people who work tirelessly to ensure these pillars of a free and fair society outlast this authoritarian spasm.
I’m thankful for the creators—the ones making the music, writing the words, conjuring the new and unexpected art forms, and drawing forth visions of the possible that can see us through this dark time.
I’m thankful for the elders. Not the arrested-development adolescents wandering the halls of power in old people’s bodies. True elders, people with the wisdom the world so badly needs. May we listen; may we become one ourselves.
I’m thankful for the dreams of young people that spring eternal, with each new generation, and renew the world’s purpose: to let them thrive.
I’m thankful for the beauty of nature. I’ll grieve coral reefs the rest of my days, but I saw them; I witnessed that wonder of creation and I’m grateful. And though I long for a time when witnessing nature’s beauty was simply about awe, not grief, I wasn’t born then. Learning to hold grief and wonder together not only spares us from emotionally shutting down but can open a deep well of strength and equanimity.
I’m thankful for the resilient living Earth. I’m thankful for all that she has absorbed of our foolishness: the consumption, the fossil-fuel pollution, the bottomless corporate greed—she has spared us the true cost of it all. But now the atmosphere is trapping ever more heat; the oceans break out in fevers; the land endures the drought, floods, and fires of its more violent climate. Ecosystems collapse, people suffer, animals are made extinct. This is the Earth seeking new equilibrium; this is the future; we will be less shielded from the consequences of our choices. And yet… the Earth adapts and, if given a chance, life will always seek to thrive.
I’m thankful for the people who, their lifeways tied to the Earth, continue to stand against the madness and for right relations with nature and each other. Around the world, Indigenous people who have suffered immeasurably in these centuries of colonial extraction, but endured, are raising voices and showing ways forward, including at COP30 in Brazil. They’ve been offering wisdom we should have heeded, just as the Mayflower colonists should have heeded, but it’s not too late.
I’m thankful for those cracks, the ones that seem to be appearing everywhere. Bayo Akomolafe says, “The crack is the monster’s gift,” a weakness in the wall, an opening on which to pry. Vanessa Machado de Oliveira invites us to use these openings to “hospice modernity,” to gently deconstruct the sources of destruction, and to grow in their place the world the world needs. More than I can ever recall, so many people seem to sense that world, waiting to be grown; are planting seeds and tending; are questioning what we as humans really need to live rich lives and creating community that can meet those needs. So many of us are now searching for a bridge to the world we need. I’m thankful that we’re searching together and for the possibilities we may find. No one knows where this is going—why can’t it be somewhere beautiful?
And I’m thankful for our capable, willing hands, yours and mine. We’re going to need to pry at the cracks and plant for tomorrow, together. We’re going to need to raise defiant fists and hold out compassionate palms. And we’re all going to need to hold hands as we meet what comes. I wish I had simpler things to tell my children about this moment, I wish giving thanks was simpler. But they are teens and young adults now and their time here will not be simple, so I tell them the truth: Some things are lost. A lot can be saved. I won’t see the world we’re trying to reach. I hope you will. All we can do today is build a bridge to that world. All we can do is hold hands tightly and be the bridge.
Happy Thanksgiving.

'Our New Reality': Planet Reaches First Climate Tipping Point With Coral Reef Dieback
“We can no longer talk about tipping points as a future risk,” said one researcher. “This is our new reality.”
Oct 13, 2025
Less than two years after researchers at the University of Exeter in the United Kingdom warned that the world was nearing numerous climate tipping points, a report out Monday warns that one such "point of no return" has already been reached, with warm-water coral reefs "experiencing unprecedented dieback."
Surging global temperatures, especially in recent years, have pushed the world's coral reefs into a state of widespread decline, with the worst bleaching event on record taking place since 2023. More than 84% of the world's reefs have been impacted.
In the Global Tipping Points Report 2025 released Monday, the researchers warned that "the central estimate" of coral reefs' "tipping point of 1.2°C global warming has been crossed," with planetary heating now at about 1.4°C above preindustrial levels.
The warming waters have caused widespread bleaching of coral reefs, which impacts the nearly a million species of marine animals and organisms that rely on them to support some of the planet's most diverse ecosystems.
“Unless we return to global mean surface temperatures of 1.2°C (and eventually to at least 1°C) as fast as possible, we will not retain warm-water reefs on our planet at any meaningful scale,” the report says. Minimizing non-climatic stressors, particularly improved reef management, can give reefs the best chance of surviving under what must be a minimal exceedance of their thermal tipping point."
The decline of coral reefs also leaves coastal communities without natural barriers against storm surge, compounds the overfishing crisis by depriving fish of a habitat in which to reproduce, and impacts thousands of jobs and billions of dollars in reef tourism each year.
"As we head into the COP30 climate negotiations it’s vital that all parties grasp the gravity of the situation."
"We can no longer talk about tipping points as a future risk,” Steve Smith, a social scientist at the University of Exeter and a lead author of the report, told Nature. “This is our new reality.”
The arrival of the tipping point necessitates immediate, significant reductions in fossil fuel emissions that are driving planetary heating in order to return to a global mean surface temperature of 1.2°C over preindustrial temperatures, but climate scientist Bill McGuire did not mince words Monday regarding the likelihood of mitigating the damage already done to coral reefs.
"We won't reduce temps to 1.2°C as soon as possible, so this is the death knell for most of the world's stupendous reef communities," said McGuire. "Other tipping points will follow."
The report notes that the world is still headed toward other climate tipping points, namely the "large-scale" degradation of the Amazon rainforest, which is projected to "weaken global climate regulation" and accelerate biodiversity loss; the melting of mountain glaciers like Áakʼw Tá Hít in Alaska; and for the Atlantic Meridional Overturning Circulation (AMOC), which regulates the climate by transporting warmer waters from the tropics to the northern Atlantic Ocean, whose likelihood of reaching a tipping point "increases with global temperature" rise.
Without rapid cuts to greenhouse gas emissions, the Global Tipping Points report says, the upper threshold of global temperature rise for coral reefs of 1.5°C is likely to be reached within 10 years.
“We are going to overshoot 1.5°C of global warming probably around 2030 on current projections,” Tim Lenton of the University of Exeter’s Global Systems Institute told The Guardian.
Manjana Milkoreit, a co-author of the report and political scientist at the University of Oslo, told Nature that "we have the knowledge regarding how to stop the Earth from reaching more tipping points."gr
“What we need is a kind of governance that matches the nature of this challenge," she said.
The report also acknowledges "positive tipping points" that could have runaway impacts on the ability to rapidly draw down greenhouse gas emissions, such as the widespread adoption of regenerative agricultural practices and an acceleration in the transition toward electric vehicle and solar power use.
"Solar PV panels have dropped in price by a quarter for each doubling of their installed capacity. Batteries have improved in quality and plummeted in price the more that are deployed," reads the report. "This encourages further adoption. The spread of climate litigation cases and nature positive initiatives is also self-amplifying. The more people undertaking them the more they influence others to act."
Lenton told The Guardian that "the race is on to bring forward these positive tipping points to avoid what we are now sure will be the unmanageable consequences of further tipping points in the Earth system."
As Common Dreams reported last week, global progress toward transitioning away from fossil fuels and expanding the use of renewable energy is surging worldwide—but the US has been left out this year under President Donald Trump, with a major spending bill imposing new fees on solar and wind development and boosting drilling on public lands while the US Department of Energy is investing $625 million in coal.
The Global Tipping Points report was released four weeks before global leaders are set to meet in Belém, Brazil for the 30th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP30), where policymakers will be asked to contribute to a Granary of Solutions: "a reservoir of concrete tools and initiatives—scalable, replicable, and aligned with the Paris Agreement—that connect ambition with implementation" in order to trigger "positive tipping points of transformation leveraging solutions that already exist."
"As we head into the COP30 climate negotiations it’s vital that all parties grasp the gravity of the situation,” Mike Barrett, chief scientific adviser at the World Wide Fund for Nature in the UK and a co-author of the report, told Yale Environment 360. “Countries must show the political bravery and leadership to work together and achieve them.”

'Graveyard of Corals': Bleaching Led to Great Barrier Reef's Worst Die-Off on Record
"We will ultimately get to a tipping point where coral cover can't bounce back," warned one researcher. "We have to mitigate the root causes of the problem and reduce emissions and stabilize temperatures."
Aug 06, 2025
After last year's climate-fueled bleaching in Australia's famed Great Barrier Reef, large swaths of the GBR suffered the worst coral die-off since records began, a government report revealed Wednesday, prompting renewed calls for reducing greenhouse gas emissions as well as reef conservation and restoration.
The GBR "experienced unprecedented levels of heat stress, which caused the most spatially extensive and severe bleaching recorded to date," the Australian Institute of Marine Science's (AIMS) annual report states.
AIMS studied the health of 124 coral reefs between August 2024 and May 2025 and found that northern and southern branches of the approximately 1,400-mile (2,300 km) GBR suffered the "largest annual decline in coral cover" ever recorded since monitoring began nearly 40 years ago.
Data collected last year from aerial surveys showed that 75% of the GBR had been bleached amid record heat driven by the worsening climate emergency. The U.S. National Oceanic and Atmospheric Administration warned in March 2024 that the bleaching would likely be the worst the world had ever seen.
The new report confirmed that "the 2024 event had the largest spatial footprint ever recorded on the GBR, with high to extreme bleaching prevalence observed across all three regions" of the GBR.
According to AIMS:
In 2025, hard coral cover declined substantially across the GBR, although considerable coral cover remains in all three regions. Regional declines ranged between 14% and 30% compared to 2024 levels, with some individual reefs experiencing coral declines of up to 70.8%. These declines are primarily attributed to coral mortality from the 2024 mass coral bleaching event, compounded by the cumulative impacts of two cyclones in December 2023 and January 2024, freshwater inundation, and some crown-of-thorns starfish activity.
In 2025, 48% of surveyed reefs underwent a decline in percentage coral cover, 42% showed no net change, and only 10% had an increase. Reefs with stable or increasing coral cover were predominantly located in the central GBR.
Scientists described the resulting seascape as a "graveyard of corals."
AIMS research lead Mike Emslie told Agence France-Presse that the "number one cause" of GBR coral decline "is climate change."
"There is no doubt about that," Emslie added.
The problem is by no means limited to the GBR. A mass global bleaching event has devastated more than 80% of the world's coral reefs over the past two years, affecting 82 countries and territories.
Prior to the current die-off, the last major GBR bleaching event occurred in 2014-17, when scientists said nearly one-third of its coral died and approximately 15% of all reefs worldwide experienced major coral deaths.
"These impacts we are seeing are serious and substantial and the bleaching events are coming closer and closer together," Emslie said in a separate interview with The Guardian.
"We will ultimately get to a tipping point where coral cover can't bounce back because disturbances come so quickly that there's no time left for recovery," he warned. "We have to mitigate the root causes of the problem and reduce emissions and stabilize temperatures."
AIMS called for greater global efforts to reduce the greenhouse gas emissions fueling planetary heating, "continued good local management," and more interventions "to help corals adapt and recover."
Larissa Waters, leader of the Australian Greens and a federal senator representing Queensland, on Monday urged the governing Labor Party to "follow the science, set 2035 targets at net-zero, stop new coal and gas, or risk losing our reef, its immense biodiversity, and the 60,000 jobs it sustains."
