Scientists have, for the first time, observed the unleashing of an enormous glacial lake flooding event in East Greenland. The rare outburst involved 3,000-plus billion liters of meltwater bursting forth in a matter of weeks.

Witnessed by researchers from the University of Copenhagen, the natural phenomenon provides insight into the powerful and potentially dangerous forces that can be released by meltwater, a press release from University of Copenhagen’s Niels Bohr Institute said.

“Imagine an enormous bathtub atop a mountain filled with water equivalent to three times Denmark’s annual water consumption, and then suddenly bursting. This is essentially what happened when the massive Catalina Lake in East Greenland released 3.4 cubic kilometers of meltwater — 3,000 billion liters — into the Scoresby Sound fjord,” the press release said.

The enormous volume of water released by the lake made it one of the three largest events of its kind ever to be documented.

The meltwater outburst flood happened from September 23 to October 11, during which time the water level of Catalina Lake fell by 154 meters. The scientists were able to use satellite imagery to observe the spectacle in real time.

“We have previously found traces of similar outburst floods, but due to polar night and clouds obstructing the potential for satellite observations, this is the first time that researchers have been able to monitor an event and measure the water volumes in real time,” explained Aslak Grinsted, a climate researcher with the Niels Bohr Institute, in the press release.

The outburst flood was caused by the accumulation of meltwater from Catalina Lake over the last two decades. The lake sits nestled in a valley obstructed by the Edward Bailey Glacier. As the lake filled up, the water started to lift the glacier, resulting in a 25-kilometer-long, carved-out tunnel underneath the ice. The pressure from the water building up finally caused it to burst into Scoresby Sound, the largest fjord on Earth.

The phenomenon of a glacial lake gradually filling and releasing its meltwater in a rush is known as a Glacial Lake Outburst Flood (GLOF).

Events such as this have been happening more often in the past 30 years due to global heating and climate change.

“The danger from glacier-dammed lakes is increasing due to global warming. It’s vital to improve our understanding of this phenomenon to issue timely warnings should there be an imminent risk,” Grinsted warned.

The recent GLOF in East Greenland did not cause any harm due to the area’s sparse population. However, floods like this can be catastrophic in more populated areas such as the Himalayas, where villages are frequently destroyed. A 2023 study found that 15 million people globally live under threat of dangerous glacial floods.

“I expect that we will witness outbursts from even larger ice-dammed lakes as Greenland’s ice sheet retreats in coming centuries. At the end of the last Ice Age, Lake Missoula had an outburst that was 2,500 times larger than the recent Catalina event. To understand these massive forces, we must study the largest outbursts when they occur,” Grinsted said. “In this case, the energy released by the glacier flood was equivalent to the output of the world’s largest nuclear power plant running at full capacity for 22 days.”

Grinsted said it was worth considering how the incredible power of such natural phenomena could be harnessed as a green energy source. The energy produced by the event at Catalina Lake could theoretically have generated 50 megawatts of electricity, which is enough to power a small town.

In this instance, however, the closest human settlement of 350 residents was 180 kilometers away, which would pose a major technological challenge for energy transmission and potential use.

“As with many other natural resources in Greenland, infrastructure is a problem. But if a brilliant engineer could figure out how to harness these meltwater outbursts, there’s enormous power and energy potential in them,” Grinsted concluded.

“The danger from glacier-dammed lakes is increasing due to global warming. It’s vital to improve our understanding of this phenomenon to issue timely warnings should there be an imminent risk,” says Grinsted.

8 Ways to Reduce Your Impact Today

Published

on

With a full-time job, an active social life, and perhaps a kid or a pup to raise, it can be tough to fit in a commitment to the environment — especially if it seems to require added cost or responsibility.
Take heart, though, because there are many simple ways to reduce your impact on the planet that actually help you save money. Once you’re up to speed with the basics like changing your incandescent light bulbs to energy-efficient LEDs and shopping with reusable bags, check out these equally easy ways to simplify your go-go life.

This article contains affiliate links. If you make a purchase through these links we will receive a small commission from the sale that helps fund our work.

1. Say ‘No’ to To-Go Waste

Even if you’re constantly on the run, it’s possible to reduce the amount of waste you generate by packing your own reusable mug, water bottle, food containers, and cutlery. The majority of restaurant to-go containers are still made from plastics that don’t recycle easily, so they’re used once and then thrown away. Each plastic cup, fork, straw, and clamshell box costs money, and you can be sure this cost is passed onto consumers — not to mention the environmental costs of all that plastic waste.

2. Water Well

Water is a precious resource, which is often a fact overlooked in developed countries where we can just turn on the tap and get clean, safe water. However, according to a 2025 WHO/UNICEF report, 2.1 billion people globally still lack access to safely managed drinking water, and the global potable water supply is under pressure from climate change and population growth. You can decrease your water consumption by following a few simple steps.

Flush and run sparingly: The average toilet uses between 1.6 and 5.5 gallons of water per flush. If you are already “letting it mellow,” save even more water by turning on the tap only when absolutely necessary. There’s no need for the water to run when brushing your teeth, washing your hands, or doing the dishes, for example.

Make sure it’s really dirty before washing: Clothing, dishes, and your body should undergo the wash and rinse cycle only when necessary. Use the same water glass all day, and wear those jeans more than once.

3. Hang It Out to Dry

Clothes dryers are among the most energy-intensive household appliances. Most of us are not willing to give up cold milk and crisp veggies from the fridge, but we can easily use the dryer less often, which can add up to significant savings of energy and money.

As an added bonus, letting your clothes air dry extends their usable lives (it is much less taxing on the stitching and fabric), it gives you a good excuse to get outside in nice weather, and line-dried laundry smells better too! If you live in a place where drying clothes outside right now would mean wearing duds that are cold and wet, consider using indoor drying racks to accomplish the same energy-free job.

4. Lights, Camera, Out!

Many electronic devices — such as phone and camera chargers, televisions, and computers — continue to draw energy even when in the “off” position. To avoid phantom power use, unplug such devices or plug everything into a power strip you can turn off when not in use. Encourage these same practices at your workplace. And no matter where you are, always turn off unnecessary lights.

5. Be a Wise Post-Consumer

In the digital age, many of us still rely on a steady stream of paper in our offices, kitchens, and bathrooms. Here are some easy suggestions for keeping more trees outside.

Print sparingly: When you do need to hold a document in your hand, be sure it has been printed and/or copied on both sides, and of course, be sure to recycle when done.

Buy the highest level of post-consumer, recycled paper: From toilet paper to notebooks, there is rarely a reason to use virgin paper. Look for the percentage on the packaging (such as products made with 100% recycled or 50% post-consumer materials), and also look for paper that is processed chlorine-free (PCF).

Class it up with cloth: Reusable napkins are not just for fancy dinner parties. They can be washed and reused indefinitely. The same goes for old T-shirts or towels, which can be repurposed as rags and used instead of disposable paper towels.

6. Resist the Urge to Splurge

A lack of excess cash can serve as a great excuse to reduce your consumption. Here are a few suggestions to help you consume less.

Take a consumption vacation: Consider taking the day or week off from making any new purchases, with the exception of necessities such as health products and food. By doing this, you’re not only saving money, but you’re also reducing the waste created throughout the life cycle of each new product, the packaging used, and the fuel consumed and produced in transporting products from the original resources to the manufacturer to your local store.

Buy nice, don’t buy twice: For necessities, make sure that you buy the highest quality, most energy-efficient, environmentally friendly model available within your budget. From appliances (Energy Star) to food (Local Harvest), there are low-impact alternatives for almost everything on the market.

7. Bid Your Car Adieu

We are a society that loves our cars, but there are many alternatives to a day spent solo in your gas-guzzling ride. Backing out of your car rut can also provide new opportunities to socialize and get some exercise.

Get on the bus: Many cities and towns have excellent public transportation systems that include buses, subways, and trains. You’ll be surprised at the new friends you make or the added reading time you find when not behind the wheel.

Carpool with friends or co-workers: Rideshare services now make it easier than ever to find a match. Uber’s UberX Share allows passengers traveling in the same direction to share a ride and reduce costs while cutting emissions. Lyft and Waze discontinued their shared rides programs in 2023.

Get on a bike or walk: While riding your bike or walking might take a little longer to reach your destination, the fresh air, reduced carbon emissions, and the exercise more than make up for the extra minutes.

Phone it in: Explore telecommuting or teleconferencing options with your employer to significantly reduce your daily commute. According to Global Workplace Analytics, a typical employer can save an average of $11,000 per half-time remote worker per year, while employees save between $2,000 and $6,500 annually from reduced commuting and related costs. Telecommuting just a few days a week will save you and your employer money.

8. Ban Planned Obsolescence

The more we view potential waste as building blocks for new products, the lower our overall impact will be. Granted, some products (“gum” comes to mind) are decidedly single-use items, but with a little creativity, many others can easily be creatively repurposed.

Sustainability In Your Ear: Peter Fusaro’s Wall Street Green Summit Explores Financing The Renewables Transition

Global investment in the energy transition reached $2.2 trillion in 2025, up 5% from the previous year despite political headwinds intensified. Peter Fusaro has watched this market evolve from a niche curiosity into a systemic financial concern. As founder of the Wall Street Green Summit, he’s spent a quarter century connecting capital to climate solutions. This year’s summit, the 25th in its history, will take place on March 10 and 11 in New York. This critical conversation arrives at an historic inflection point: insurance companies are withdrawing from climate-vulnerable states, AI data centers are straining electrical grids, and the economics of clean energy have fundamentally shifted.

Peter Fusaro, Founder of the Wall Street Green Summit, is our guest on Sustainability In Your Ear.

The energy transition’s bottleneck isn’t capital, it’s infrastructure. The U.S. went from 110 investor-owned utilities in 1992 to just 40 today, and consolidation meant underinvestment in transmission and distribution. Data centers consumed 2% of U.S. energy demand in 2020; Peter sees that climbing to 10-12% by 2030. Blackouts and brownouts are inevitable, he says. Yet his message is pragmatic optimism: ignore Washington and watch the capital markets and blue states where climate policy is embedded in law. Many companies are “green hushing,” quietly pursuing sustainability without public positioning. The energy industry thinks in 40-year cycles, making the current political moment a blip. “I’ve spent 56 years now in sustainability, before it had a name,” he says. “What I’ve learned is change takes decades.”

Peter argues that Wall Street has genuinely internalized climate as systemic risk—not because of ideology, but because of opportunity. “Wall Street likes exchanges, likes to trade, likes volatility, and certainly likes uncertainty,” he explains. “What people don’t understand about Wall Street, it’s about the edge. What’s the arbitrage opportunity?” The reinsurance industry has stepped forward aggressively, funding carbon credits and sustainability projects. Peter’s recent Earth911 article, “Climate Risk Has Become a Defining Economic Issue,” explores these themes in depth.

However, he sees natural gas and renewables dominating the next 15 years, while geothermal is enjoying a genuine renaissance. His optimism rests on a demographic bet: “I have a tremendous valuation on young people. I’m 75. They’re inheriting this world, and they get the sustainability message globally.” The summit attendees includes no government officials and no academics, just people in the trenches building and financing solutions.

Earth911 Inspiration: Nothing Is Perfect and Everything Is Perfect

Published

on

Sustainability is a series of experiments. No one is perfect and too many people don’t try to help the Earth because they think they won’t make a difference. Author Alice Waters reminds us that every tree is beautiful and we can be, too, if we forget perfection and focus on living well: “In nature, nothing is perfect and everything is still perfect. Trees can be contorted, bent in weird ways, and they’re still beautiful.”
