In a victory for environmental, health and community activists, fracking has been banned in New York state. That was the conclusion reached at a public, livestreamed meeting of Governor Andrew Cuomo's cabinet in Albany today. Commissioner of the Department of Environmental Conservation Joseph Martens issued the order, following a report on his own findings and a strongly cautionary report from Dr. Howard Zucker, commissioner of the Department of Health, who compared the unknown health impacts of fracking to those of secondhand smoke, once considered benign.
The hearing opened unpromisingly with Cuomo making what sounded like condescending remarks on the issue.
"I’ve been asked about 46,000 times at various decibel levels," he said as he introduced the subject. "The dialogue on fracking is an emotional one, both pro and con. You talk to anti-frackers for 30 seconds and they’re yelling and they’re passionate and emotional and scared and they’re not listening and they’re not hearing and they’re yelling. You listen to pro-frackers and same thing. This is probably the most emotionally charged issue I’ve experienced, more emotionally charged than marriage equality, more emotionally charged than the gun issue, more emotionally charged than the death penalty."
But he added, "I'm not a scientist. I'm not a health expert. I'm not a doctor. I'm not an environmentalist. So let's bring the emotion down and ask qualified experts what their opinions is. My two cents on the matter is I will defer to these two gentlemen."
"Those two gentlemen" he referred to were Martens and Zucker. They spoke following Cuomo's remarks and their conclusion was clear: no fracking in New York.
Martens addressed some of the aspects that made fracking impractical and economically unattractive in the state, including the large areas that would be off limits to fracking due to endangering water supplies or local bans on drilling, which were ruled legal in the state by a court decision in June, finding in favor of the town of Dryden which enacted a ban. He also presented evidence that the highly touted evidence of the economic benefits of fracking to the region was questionable at best.
But it was Zucker who made the most powerful case against letting fracking go forward.
"The questions one would want answered are, is my water safe enough to drink, is my air safe to breath, can I grow vegetables in my garden, the effects on reservoirs that provide drinking water to 9 million people in New York City," he said.
He referred to numerous studies, saying that they raised concerns about water and air contamination, health impacts on those living near wells and the increase in noise, odors, traffic and traffic fatalities.
"There are many red flags, questions that remain unanswered," he said. "Bonafide scientific literature is now emerging. Most studies have been in the last two years. The bottom line is we lack long-term comprehensive studies. They're not yet completed or yet to be initiated. The science isn’t there. These concerns gives me reason to pause."
"Governor, you asked me for my opinion and said, let the science decide," Zucker concluded. "Would I live in a community with high-volume hydraulic fracking, based on facts I have now? After looking at plethora of reports, my answer is no. Until the public health red flags are answered by valid evidence, I cannot support high volume hydraulic fracking in the great state of New York."
Based on that conclusion, Martens said he would issue a legally binding statement prohibiting fracking in the state.
Following their presentations, Cuomo said, "Dr. Zucker, I found your statement especially effective. What I found most powerful in your presentation is you wouldn’t let your family live in an area with high-volume fracking. If you don’t believe your children should live there, your duty is to suggest no child should live there."
Ever the politician, Cuomo wrapped up saying, "This is self-executing between you two gentlemen. I have nothing to do with it."
So he can technically say he didn't ban fracking in New York. But for the foreseeable future, there will be no fracking in New York. The ban makes permanent a moratorium put in place in 2008 that kicked the decision down the road; it was set to expire in 2017. Cuomo said earlier this week a decision would be made by the end of the year, and some activists were afraid the governor favored letting fracking proceed.
Needless to say, environmental groups were elated that they'd won their hard-fought battle.
"Our growing national movement has persevered," said Wenonah Hauter of Food & Water Watch. "We applaud Governor Cuomo for acknowledging the overwhelming science that speaks to the inherent dangers of fracking to public health and the environment. Fracking has no place in New York or anywhere, and the governor has smartly seized a golden opportunity to be a real national leader on health, environmental protection and a future free of polluting fossil fuels."
"By banning fracking, Governor Cuomo has set himself apart as a national political leader who stands up for people and not for the interests of the dirty fuel lobby," said Sierra Club executive director Michael Brune. "Today’s decision will shake the foundations of our nation’s flawed energy policy, and we can only expect that it will give strength to activists nationwide who are fighting fracking in dozens of states and hundreds of cities and counties. The Sierra Club also extends heartfelt congratulations to all of the passionate anti-fracking activists in New York who were relentless in telling the truth about the dangers of fracking, persevered years of opposition from the oil and gas lobby, and ultimately prevailed."
“This is truly a monumental day," said Earthjustice managing attorney Deborah Goldberg, who represented Dryden in the June decision. "Governor Andrew Cuomo has earned a place in history. Never before has a state with proven gas reserves banned fracking. I believe that future generations will point to this day and say 'This is when the tide began to turn against the dirty, dangerous and destructive fossil fuel industry.’ We hope that this determined leadership Governor Cuomo has displayed will give courage to elected leaders throughout the country and world: fracking is too dangerous and must not continue.”
Other health professionals shared Dr. Zucker's concerns about fracking's health effects.
"Concerned Health Professionals of NY congratulates Governor Cuomo and his administration for listening to the science on drilling and fracking and putting public health first by prohibiting fracking in New York State," said the group's co-founder Dr. Larysa Dyrszka. "As hundreds of peer-reviewed papers have shown, drilling and fracking threaten to have very serious public health and environmental impacts on families and communities. Governor Cuomo put the science first and acted in the best interest of all New Yorkers and future generations. We hope that Governor Cuomo's wise decision will have ripple effects across the country and the world."
And many praised the community activists who organized, protested, rallied and lobbied.
"This victory for health and climate belongs to the thousands of grassroots organizers who led a years long fight to defend their communities from Big Oil and Gas," said 350.org’s fracking campaign manager Linda Capato. "They defeated millions of dollars in lobbying and paid misinformation with grassroots energy and bold organizing. This is also a huge win for the anti-fracking movement nationwide. The same health and environmental concerns that led to the ban in New York are present everywhere. Once they have the facts, people across the country will clearly agree with New Yorkers that it is more important to put the health of our children and climate over industry greed."
350.org founder Bill McKibben added, "This is exactly what happens when people organize with enormous skill and dedication. People, especially scattered in small towns across upstate New York—with some help from the big city—showed the whole movement how it's done. 350.org will be continuing to support the movement to stop fracking in New York and across the United States."

These longer periods of stratification could have "far-reaching implications" for lake ecosystems, the paper says, and can drive toxic algal blooms, fish die-offs and increased methane emissions.
The study, published in Nature Communications, finds that the average seasonal lake stratification period in the northern hemisphere could last almost two weeks longer by the end of the century, even under a low emission scenario. It finds that stratification could last over a month longer if emissions are extremely high.
If stratification periods continue to lengthen, "we can expect catastrophic changes to some lake ecosystems, which may have irreversible impacts on ecological communities," the lead author of the study tells Carbon Brief.
The study also finds that larger lakes will see more notable changes. For example, the North American Great Lakes, which house "irreplaceable biodiversity" and represent some of the world's largest freshwater ecosystems, are already experiencing "rapid changes" in their stratification periods, according to the study.
'Fatal Consequences'
As temperatures rise in the spring, many lakes begin the process of "stratification." Warm air heats the surface of the lake, heating the top layer of water, which separates out from the cooler layers of water beneath.
The stratified layers do not mix easily and the greater the temperature difference between the layers, the less mixing there is. Lakes generally stratify between spring and autumn, when hot weather maintains the temperature gradient between warm surface water and colder water deeper down.
Dr Richard Woolway from the European Space Agency is the lead author of the paper, which finds that climate change is driving stratification to begin earlier and end later. He tells Carbon Brief that the impacts of stratification are "widespread and extensive," and that longer periods of stratification could have "irreversible impacts" on ecosystems.
For example, Dr Dominic Vachon – a postdoctoral fellow from the Climate Impacts Research Centre at Umea University, who was not involved in the study – explains that stratification can create a "physical barrier" that makes it harder for dissolved gases and particles to move between the layers of water.
This can prevent the oxygen from the surface of the water from sinking deeper into the lake and can lead to "deoxygenation" in the depths of the water, where oxygen levels are lower and respiration becomes more difficult.
Oxygen depletion can have "fatal consequences for living organisms," according to Dr Bertram Boehrer, a researcher at the Helmholtz Centre for Environmental Research, who was not involved in the study.
Lead author Woolway tells Carbon Brief that the decrease in oxygen levels at deeper depths traps fish in the warmer surface waters:
"Fish often migrate to deeper waters during the summer to escape warmer conditions at the surface – for example during a lake heatwave. A decrease in oxygen at depth will mean that fish will have no thermal refuge, as they often can't survive when oxygen concentrations are too low."
This can be very harmful for lake life and can even increase "fish die-off events" the study notes.
However, the impacts of stratification are not limited to fish. The study notes that a shift to earlier stratification in spring can also encourage communities of phytoplankton – a type of algae – to grow sooner, and can put them out of sync with the species that rely on them for food. This is called a "trophic mismatch."
Prof Catherine O'Reilly, a professor of geography, geology and the environment at Illinois State University, who was not involved in the study, adds that longer stratified periods could also "increase the likelihood of harmful algae blooms."
The impact of climate change on lakes also extends beyond ecosystems. Low oxygen levels in lakes can enhance the production of methane, which is "produced in and emitted from lakes at globally significant rates," according to the study.
Woolway explains that higher levels of warming could therefore create a positive climate feedback in lakes, where rising temperatures mean larger planet-warming emissions:
"Low oxygen levels at depth also promotes methane production in lake sediments, which can then be released to the surface either via bubbles or by diffusion, resulting in a positive feedback to climate change."
Onset and Breakup
In the study, the authors determine historical changes in lake stratification periods using long-term observational data from some of the "best-monitored lakes in the world" and daily simulations from a collection of lake models.
They also run simulations of future changes in lake stratification period under three different emission scenarios, to determine how the process could change in the future. The study focuses on lakes in the northern hemisphere.
The figure below shows the average change in lake stratification days between 1900 and 2099, compared to the 1970-1999 average. The plot shows historical measurements (black), and the low emission RCP2.6 (blue), mid emissions RCP6.0 (yellow) and extremely high emissions RCP8.5 (red) scenarios.

The plot shows that the average lake stratification period has already lengthened. However, the study adds that some lakes are seeing more significant impacts than others.
For example, Blelham Tarn – the most well-monitored lake in the English Lake District – is now stratifying 24 days earlier and maintaining its stratification for an extra 18 days compared to its 1963-1972 averages, the study finds. Woolway tells Carbon Brief that as a result, the lake is already showing signs of oxygen depletion.
Climate change is increasing average stratification duration in lakes, the findings show, by moving the onset of stratification earlier and pushing the stratification "breakup" later. The table below shows projected changes in the onset, breakup and overall length of lake stratification under different emission scenarios, compared to a 1970-1999 baseline.
The table shows that even under the low emission scenario, the lake stratification period is expected to be 13 days longer by the end of the century. However, in the extremely high emissions scenario, it could be 33 days longer.
The table also shows that stratification onset has changed more significantly than stratification breakup. The reasons why are revealed by looking at the drivers of stratification more closely.
Warmer Weather and Weaker Winds
The timing of stratification onset and breakup in lakes is driven by two main factors – temperature and wind speed.
The impact of temperature on lake stratification is based on the fact that warm water is less dense than cool water, Woolway tells Carbon Brief:
"Warming of the water's surface by increasing air temperature causes the density of water to decrease and likewise results in distinct thermal layers within a lake to form – cooler, denser water settles to the bottom of the lake, while warmer, lighter water forms a layer on top."
This means that, as climate change causes temperatures to rise, lakes will begin to stratify earlier and remain stratified for longer. Lakes in higher altitudes are also likely to see greater changes in stratification, Woolway tells Carbon Brief, because "the prolonging of summer is very apparent in high latitude regions."
The figure below shows the expected increase in stratification duration from lakes in the northern hemisphere under the low (left), mid (center), and high (right) emission scenarios. Deeper colors indicate a larger increase in stratification period.

The figure shows that the expected impact of climate change on stratification duration becomes more pronounced at more northerly high latitudes.
The second factor is wind speed, Woolway explains:
"Wind speed also affects the timing of stratification onset and breakdown, with stronger winds acting to mix the water column, thus acting against the stratifying effect of increasing air temperature."
According to the study, wind speed is expected to decrease slightly as the planet warms. The authors note that the expected changes in near-surface wind speed are "relatively minor" compared to the likely temperature increase, but they add that it may still cause "substantial" changes in stratification.
The study finds that air temperature is the most important factor behind when a lake will begin to stratify. However, when looking at stratification breakup, it finds that wind speed is a more important driver.
Meanwhile, Vachon says that wind speeds also have implications for methane emissions from lakes. He notes that stratification prevents the methane produced on the bottom of the lake from rising and that, when the stratification period ends, methane is allowed to rise to the surface. However, according to Vachon, the speed of stratification breakup will affect how much methane is released into the atmosphere:
"My work has suggested that the amount of accumulated methane in bottom waters that will be finally emitted is related to how quickly the stratification break-up occurs. For example, a slow and progressive stratification break-up will most likely allow water oxygenation and allow the bacteria to oxidise methane into carbon dioxide. However, a stratification break-up that occurs rapidly – for example after storm events with high wind speed – will allow the accumulated methane to be emitted to the atmosphere more efficiently."
Finally, the study finds that large lakes take longer to stratify in spring and typically remain stratified for longer in the autumn – due to their higher volume of water. For example, the authors highlight the North American Great Lakes, which house "irreplaceable biodiversity" and represent some of the world's largest freshwater ecosystems.
These lakes have been stratifying 3.5 days earlier every decade since 1980, the authors find, and their stratification onset can vary by up to 48 days between some extreme years.
O'Reilly tells Carbon Brief that "it's clear that these changes will be moving lakes into uncharted territory" and adds that the paper "provides a framework for thinking about how much lakes will change under future climate scenarios."

Currently the U.S. Supreme Court has on its docket a case between Texas, New Mexico and Colorado and another one between Mississippi and Tennessee. The court has already ruled this term on cases pitting Texas against New Mexico and Florida against Georgia.
Climate stresses are raising the stakes. Rising temperatures require farmers to use more water to grow the same amount of crops. Prolonged and severe droughts decrease available supplies. Wildfires are burning hotter and lasting longer. Fires bake the soil, reducing forests' ability to hold water, increasing evaporation from barren land and compromising water supplies.
As a longtime observer of interstate water negotiations, I see a basic problem: In some cases, more water rights exist on paper than as wet water – even before factoring in shortages caused by climate change and other stresses. In my view, states should put at least as much effort into reducing water use as they do into litigation, because there are no guaranteed winners in water lawsuits.

Dry Times in the West
The situation is most urgent in California and the Southwest, which currently face "extreme or exceptional" drought conditions. California's reservoirs are half-empty at the end of the rainy season. The Sierra snowpack sits at 60% of normal. In March 2021, federal and state agencies that oversee California's Central Valley Project and State Water Project – regional water systems that each cover hundreds of miles – issued "remarkably bleak warnings" about cutbacks to farmers' water allocations.
The Colorado River Basin is mired in a drought that began in 2000. Experts disagree as to how long it could last. What's certain is that the "Law of the River" – the body of rules, regulations and laws governing the Colorado River – has allocated more water to the states than the river reliably provides.
The 1922 Colorado River Compact allocated 7.5 million acre-feet (one acre-foot is roughly 325,000 gallons) to California, Nevada and Arizona, and another 7.5 million acre-feet to Utah, Wyoming, Colorado and New Mexico. A treaty with Mexico secured that country 1.5 million acre-feet, for a total of 16.5 million acre-feet. However, estimates based on tree ring analysis have determined that the actual yearly flow of the river over the last 1,200 years is roughly 14.6 million acre-feet.
The inevitable train wreck has not yet happened, for two reasons. First, Lakes Mead and Powell – the two largest reservoirs on the Colorado – can hold a combined 56 million acre-feet, roughly four times the river's annual flow.
But diversions and increased evaporation due to drought are reducing water levels in the reservoirs. As of Dec. 16, 2020, both lakes were less than half full.
Second, the Upper Basin states – Utah, Wyoming, Colorado and New Mexico – have never used their full allotment. Now, however, they want to use more water. Wyoming has several new dams on the drawing board. So does Colorado, which is also planning a new diversion from the headwaters of the Colorado River to Denver and other cities on the Rocky Mountains' east slope.

Utah Stakes a Claim
The most controversial proposal comes from one of the nation's fastest-growing areas: St. George, Utah, home to approximately 90,000 residents and lots of golf courses. St. George has very high water consumption rates and very low water prices. The city is proposing to augment its water supply with a 140-mile pipeline from Lake Powell, which would carry 86,000 acre-feet per year.
Truth be told, that's not a lot of water, and it would not exceed Utah's unused allocation from the Colorado River. But the six other Colorado River Basin states have protested as though St. George were asking for their firstborn child.
In a joint letter dated Sept. 8, 2020, the other states implored the Interior Department to refrain from issuing a final environmental review of the pipeline until all seven states could "reach consensus regarding legal and operational concerns." The letter explicitly threatened a high "probability of multi-year litigation."
Utah blinked. Having earlier insisted on an expedited pipeline review, the state asked federal officials on Sept. 24, 2020 to delay a decision. But Utah has not given up: In March 2021, Gov. Spencer Cox signed a bill creating a Colorado River Authority of Utah, armed with a $9 million legal defense fund, to protect Utah's share of Colorado River water. One observer predicted "huge, huge litigation."
How huge could it be? In 1930, Arizona sued California in an epic battle that did not end until 2006. Arizona prevailed by finally securing a fixed allocation from the water apportioned to California, Nevada and Arizona.
Litigation or Conservation
Before Utah takes the precipitous step of appealing to the Supreme Court under the court's original jurisdiction over disputes between states, it might explore other solutions. Water conservation and reuse make obvious sense in St. George, where per-person water consumption is among the nation's highest.
St. George could emulate its neighbor, Las Vegas, which has paid residents up to $3 per square foot to rip out lawns and replace them with native desert landscaping. In April 2021 Las Vegas went further, asking the Nevada Legislature to outlaw ornamental grass.
The Southern Nevada Water Authority estimates that the Las Vegas metropolitan area has eight square miles of "nonfunctional turf" – grass that no one ever walks on except the person who cuts it. Removing it would reduce the region's water consumption by 15%.
Water rights litigation is fraught with uncertainty. Just ask Florida, which thought it had a strong case that Georgia's water diversions from the Apalachicola-Chattahoochee-Flint River Basin were harming its oyster fishery downstream.
That case extended over 20 years before the U.S. Supreme Court ended the final chapter in April 2021. The court used a procedural rule that places the burden on plaintiffs to provide "clear and convincing evidence." Florida failed to convince the court, and walked away with nothing.
