"Our future," James Lovelock observed, "is like that of the passengers on a small pleasure boat sailing quietly above the Niagara Falls, not knowing that the engines are about to fail." By 2020, two-thirds of wild animals will be gone. Life is being extinguished as fast as when the dinosaurs disappeared because humanity is taking a chainsaw to the tree of life. Our best chance to save our ecosystems and 80-90% of all species is giving them enough safe space to thrive -- by keeping half the Earth intact.

Not the end of the planet, but
maybe the end of its human inhabitants
(August 10, 2018) – "Our future," scientist James Lovelock has written, "is like that of the passengers on a small pleasure boat sailing quietly above the Niagara Falls, not knowing that the engines are about to fail."
I thought about Lovelock the other day as I drove across Idaho, watching plumes from a forest fire rise in the distance. My mom and two of my kids were texting me about their experience driving through Redding, the city in Northern California where a "firenado" had devastated the region and accelerated a wildfire that killed six people. Not far away, in Mendocino, the largest fire in California history was burning an area the size of Los Angeles.
On the radio, I listened to reports from around the world: in Athens, Greece, a fire killed 92 people; in Japan, a brutal heat wave claimed 80 lives. This summer, wildfires have been burning in the United Kingdom, Denmark, Estonia, Finland, Latvia, Malta, the Netherlands, Poland and Germany. There are even wildfires in the Arctic.
High temperature records have been shattered all around the globe, including in Death Valley, California, which set the record for the hottest month ever recorded on the planet, with 21 days over 120 degrees. Our world is aflame.
I doubt any of this would surprise Lovelock, who is one of the most original thinkers of the 20th century, as well as one of the most articulate prophets of doom. As an inventor, he created a device that helped detect the growing hole in the ozone layer and jump-start the environmental movement in the 1970s.
And as a scientist, he introduced the revolutionary theory known as Gaia -- the idea that our entire planet is a kind of super-organism that is, in a sense, "alive." Once dismissed as New Age quackery, Lovelock's vision of a self-regulating Earth now underlies virtually all climate science.
And in Lovelock's view, the Earth's self-regulating system is seriously out of whack, thanks largely to our 150-year fossil fuel binge. "You could quite seriously look at climate change as a response of the system intended to get rid of an irritating species: us humans," Lovelock told me in 2007 when I visited him at his house in Devon, England, for a profile in Rolling Stone. "Or at least cut them back to size."
And Lovelock did not mince words about the future that we are creating for ourselves by ignoring the warning signs on our superheated planet. As I wrote at the time: "In Lovelock's view, the scale of the catastrophe that awaits us will soon become obvious. By 2020, droughts and other extreme weather will be commonplace. By 2040, the Sahara will be moving into Europe, and Berlin will be as hot as Baghdad.
"Atlanta will end up a kudzu jungle. Phoenix will become uninhabitable, as will parts of Beijing (desert), Miami (rising seas) and London (floods). Food shortages will drive millions of people north, raising political tensions.
"'The Chinese have nowhere to go but up into Siberia,' Lovelock says. 'How will the Russians feel about that? I fear that war between Russia and China is probably inevitable.'
"With hardship and mass migrations will come epidemics, which are likely to kill millions.
"By 2100, Lovelock believes, the Earth's population will be culled from today's 6.6 billion to as few as 500 million, with most of the survivors living in the far latitudes -- Canada, Iceland, Scandinavia, the Arctic Basin.
A new paper published last week in the Proceedings of the National Academy of Sciences called "Trajectories of the Earth System in the Anthropocene" reached more or less the same conclusion, even if was stated in more general scientific terms (and of course minus any reference to a "culling" of Earth's population).
The paper, which was widely covered by everyone from USA Today to Al Jazeera, projected a very Lovelock-ian view of our world, arguing that even if we managed to hit the carbon emissions targets set in the Paris Climate Accord, we still might trigger a series of accelerating climate-system feedback loops that would push the climate into a permanent hothouse state, with a warming of four, five or even six degrees Celsius.
If that were to happen, the paper argued, "Hothouse Earth is likely to be uncontrollable and dangerous to many, particularly if we transition into it in only a century or two, and it poses severe risks for health, economies, political stability (especially for the most climate vulnerable), and ultimately, the habitability of the planet for humans."
The idea that the Earth's climate system has certain tipping points, or thresholds, is nothing new. Small changes in the temperature of the Southern Ocean, for example, might have big implications for the West Antarctic ice sheet, leading to an ice cliff collapse that could raise sea levels by 10 feet or more in a very short (geologically-speaking) period of time.
Richard Alley, a glaciologist at Penn State, has described the Earth's climate as a highly complex system that, based on small forces that are still only dimly understood, tends to lurch from one steady state to another.
There is no groundbreaking new science in the Hothouse Earth paper. Rather, it's a synthesis of what is already known and presented in a compelling way. But it is an important reminder of two key attributes of the climate crisis.
The first is that the real threat of climate change is not a slow slide into a warmer world; it's a fast change into a radically different climate. How fast that change could happen, and how radically different it might be, no one can say for sure. But by continuing to dump fossil fuels into the atmosphere at an ever-increasing rate, we are rolling the dice.
As Columbia University scientist Wally Broecker famously put it, "If you're living with any angry beast, you shouldn't poke it with a stick."
And we are not doing nearly enough to fight it. The Hothouse Earth paper points out -- again, in a very Lovelock-ian way -- that fighting climate change is not just a matter of reducing carbon pollution in the future, important as that obviously is. It's about taking active stewardship of the planet now, and thinking more holistically about how to manage it now.
Among other things, that means giving up the notion that there is a "solution" for climate change and accepting the idea we are living in a rapidly changing world now. How will we engineer drinking water systems to deal with this? How will we manage forests? How are coastal cities going to adapt to -- or intelligently retreat from -- rapidly rising seas?
"The heat and fires we're seeing this summer is worrisome," Alley tells Rolling Stone, in his typically understated way. "There are certainly human fingerprints on a lot of it." But, Alley points out, this is just the beginning.
As of now, the Earth has warmed just 1 degree Celsius. "Dealing with what we're seeing now is the easy stuff," Alley says. "With each additional degree of warming, the impact will be greater." Alley is most concerned about physical systems with likely tipping points, such as the West Antarctic ice sheet.
He's also concerned about biological tipping points. "If the oxygen level in oceans drops just a little, it could have a big and immediate impact on sea life," Alley says. "A fire in Brazil could lead to rainforest being replaced with savannah, which would have all kinds of consequences for biological diversity, as well as for carbon uptake."
But it's the tipping point in human systems that worry Alley the most. He points to the recent drought in the Middle East, which was a key driver in the Syrian civil war. "You can see the resilience of different political systems. During the drought, Israel was OK. But Syria was not."
Maybe this is the summer that we figure out that, as Lovelock put it, our engines are about the fail and we are indeed headed over the falls. But I thought that after Hurricane Katrina, too. And after Sandy.
Instead, America elected a president who thinks climate change is a hoax and tweets insanely about how California doesn't have enough water to fight the fires because it has "diverted" rivers into the Pacific. (As University of California at Merced professor LeRoy Westerling explained to NPR, "Even if you built a massive statewide sprinkler system and drained all of our natural water bodies to operate it, it wouldn't keep up with evaporation from warmer temperatures from climate change.")
When I talked to Lovelock in his cottage in Devon 11 years ago, he wasn't worried about the fate of the planet. "Gaia is a tough bitch," he told me. Whatever we humans do to it, he argued, it will eventually recover its equilibrium, even if it takes millions of years.
What's at stake, Lovelock believes, is civilization. "I don't see it being too long before forms of life, based on the idea of [artificial intelligence] and so on, take over and run the planet for heaven knows how long."
What about humans? When asked about this recently, Lovelock told the BBC: "Don't you consider it possible that we've had our time?"
By 2020, two-thirds of wild animals will be gone. Life is being extinguished as fast as when the dinosaurs disappeared -- and it's happening because humanity is taking a chainsaw to the tree of life.
Unless we stop this tragedy, the Earth's delicate biodiversity could completely collapse, leaving our planet deathly silent and uninhabitable for humans. But there's hope -- top scientists are backing an ambitious plan to put half our planet under protection and restore harmony with our home.
Governments are meeting soon to discuss how we address the crisis. If we bring a resounding chorus of human voices behind the 50% plan, we can push governments to stop the next mass extinction.
We're testing the boundaries of our planet's ability to sustain us and all life, but the biodiversity crisis still isn't high on the political agenda! If enough of us engage now, we could change that.
Scientists say our best chance to save our ecosystems and 80-90% of all species is giving them enough safe space to thrive, then nature uses its wisdom to regenerate. The 50% plan sounds ambitious, but in fact it's totally viable, and likely the best way to sustain our intricate web of life.
But to get this off the ground we have to show our governments now that people overwhelmingly want to protect 50% from deforestation, dirty energy, and industrial fishing and agriculture. Let's start today with a massive petition for 50%, and keep building the pressure until we win!
It is a great unwisdom of our species that we have become so disconnected from our natural world. But it's not too late. We have the capacity to grow wiser. Our hope for change built this massive movement, and we won the Paris climate deal. We are within sight of protecting 50% of our planet. Let's come together, lead, and restore the harmony between humans and our home.
"We global citizens are deeply concerned by scientists warning that ecosystems critical to sustaining life on Earth could collapse in our lifetimes. We call on you to meet existing targets to protect biodiversity, forge a new agreement so that at least 50% of our lands and oceans are protected and restored, and ensure our planet is completely sustainably managed. This must take into consideration the needs of human development, and have the active support of indigenous peoples. This long-term goal for nature can restore harmony with our home."
