The Rapidly Evolving World of Grid Battery Storage
For most of the 2010s, “grid-scale battery storage” meant one thing: rows of lithium-ion racks, stacked in shipping-container-sized enclosures, doing their job quietly behind chain-link fences. Then came Moss Landing — and the industry’s relationship with that assumption changed for good. What’s followed since has been one of the more interesting sprints in energy technology: a scramble to build storage that’s not just bigger, but safer, cheaper, and better suited to keeping a renewable-heavy grid running for hours or even days at a time. Moss Landing: The Wake-Up Call California’s Moss Landing battery storage facility was once the world’s largest and a symbol of the clean energy transition. But on…

A Powerful El Niño Is Brewing—and Scientists Are Watching Closely
El Niño is a natural event where the surface water in the middle of the Pacific Ocean, near the equator, gets warmer than usual. This happens every few years, and it changes weather patterns all over the world — causing things like extra rain in some places, droughts in others, and shifts in temperature. A Record-Breaking El Niño on the Rise Scientists at NOAA say this year’s El Niño is growing fast and could become one of the strongest ever recorded since they started keeping track in 1950. There’s an 81% chance it will reach “very strong” status by fall. This El Niño only started last month, but it’s already…

Unmasking CO₂ Myths: The Science You Need to Know
Welcome to the third part of my Fact-Checking Series, where I dig into myths about carbon dioxide and clear up misunderstandings about climate. Carbon dioxide, or CO₂, is an invisible gas that is all around us in the air. It’s made up of one carbon atom and two oxygen atoms. People and animals breathe it out when we exhale, and plants take it in to help them grow through a process called photosynthesis. CO₂ is also a strong greenhouse gas, which means it traps heat in the Earth’s atmosphere. Without CO₂, our planet would be too cold for us to live. While this is natural and important for life, too…

Oohs, Ahhs, and Toxic Aftermath of Fireworks
Fireworks look amazing lighting up the night sky, but scientists have discovered they leave behind pollution that can linger long after the show is over. Three new studies looked at what really happens after the fireworks fade. Leftover Firework “Trash” Pollutes Water After fireworks explode, burned pieces and leftover chemicals fall back to the ground. Rain can wash this debris into nearby rivers and lakes, where it releases metals and other chemicals into the water. It can also change how other pollutants behave. Scientists worry this could disrupt the tiny microbes and other organisms that help keep these ecosystems healthy, especially in places where fireworks are used year after year.…

Desalination: Why Turning Ocean Water Into Drinking Water Isn’t as Easy as It Sounds
More and more cities are running out of water. In coastal areas, people often say, “There’s a whole ocean right there — why not just take the salt out and drink it?” It sounds like a simple fix. But desalination plants (the places that do this) actually cause some real problems. In addition, they don’t produce nearly as much clean water as you’d think. Let’s break down why. The Leftover Salt Has to Go Somewhere Here’s how desalination basically works: a plant sucks in ocean water and pushes it through filters to remove the salt. But here’s the catch — for every 2 cups of ocean water that go in,…

California Wildfire Severity Is Skyrocketing — And Scientists Know Why
Have you ever driven through a forest and seen a huge field of burned tree trunks, standing like ghosts? That’s what one wildfire researcher calls “tree gravestones” — and in California, they’re becoming a lot more common. A new study from UCLA looked at forest fires across the state going all the way back to 1985, and the results show just how much California wildfire severity has changed. What they found is pretty alarming: today’s forest fires burn about 10 times more land every year than fires did back in the 1980s. But here’s the part that really stands out — the most destructive type of fire, called high-severity fire,…

China Is the World’s Renewable Energy Champion
China keeps breaking records when it comes to renewable power. China’s renewable energy boom continued in the first two months of 2026, when the country added about 45 gigawatts of new green energy. That’s enough electricity to supply millions of households. Out of all the new power plants built in those two months, more than two out of every three came from solar panels and wind turbines. By the end of February, China’s total renewable energy capacity had grown to about 2,380 gigawatts. That means renewables now make up about 60% of all the power-generating capacity in the entire country–solar farms, wind turbines, hydroelectric dams, and more. China isn’t just…

The Dirty Truth About Your Produce—and How to Clean It
Strawberries may be sweet and juicy, but they made third place in this year’s “Dirty Dozen” list from the Environmental Working Group (EWG). The Dirty Dozen is an annual report that looks at which fruits and vegetables have the highest levels of pesticide residue based on testing by the U.S. Department of Agriculture. Other foods on the list include spinach, kale, blueberries, grapes, peaches, cherries, apples, pears, and potatoes. The good news is that simply rinsing fruits and vegetables under running water can remove many pesticide residues. Some scientists say you can make washing even more effective by soaking produce in water mixed with a little baking soda or vinegar.…

The AMOC Slowdown: A Warning Sign From the Atlantic
What Is the AMOC? Picture a giant conveyor belt — like the ones at a grocery store checkout — but instead of groceries, it’s moving billions of gallons of ocean water all around the planet. That’s basically what the Atlantic Meridional Overturning Circulation, or AMOC (say it like “AY-mock”), does. Here’s how it works: Warm, salty water near the tropics flows north along the surface of the Atlantic Ocean, carrying heat with it toward Europe. When this warm water reaches the cold waters near Greenland, it cools down and gets heavier. Heavy water sinks to the ocean floor, then flows back south as a deep, cold current. Eventually, that cold…

Virtual Power Plants: The Power Plant You Can’t See
Imagine if thousands of homes, businesses, and electric cars could work together like one giant power plant—without building a single smokestack or power station. That may sound like science fiction, but it’s already happening. It’s called a Virtual Power Plant, or VPP. What Is a Virtual Power Plant? A virtual power plant isn’t a real building. Instead, it’s a network of connected energy devices that work together through computers and the internet. These devices can include: On their own, each device doesn’t make much of a difference. But when thousands of them work together, they can act like a large power plant. How Does It Work? Think of a virtual…

How California’s Ocean Heat Wave Is Wiping Out Seabirds
My good friend, George is a surfer. Recently, he walked up the beach carrying his surfboard and counted seven dead birds in a distance of just 100 feet or so. So, what’s going on? A major ocean heat wave is hitting the California coast and harming wildlife — especially seabirds like pelicans, cormorants, murres, and gulls. In some places, ocean temperatures have jumped as much as 7 degrees above normal, breaking records along the coast. Scientists at the Scripps Institution of Oceanography recorded 38 days since January 1st where the water temperature off their La Jolla pier broke records dating back to 1916. Why Are Birds Starving? Warm water disrupts…

Is Global Warming Just an Urban Heat Island Effect? Scientists Say No
Have you ever noticed it’s hotter in a city than in the countryside? That’s not your imagination — it’s a real thing called the urban heat island effect. But some people claim this means global warming isn’t real, that we’re just measuring hot pavement instead of an actual warming planet. It may sound convincing at first, but the evidence doesn’t support it. First, What is the Urban Heat Island Effect? Cities are full of concrete, asphalt, and buildings that soak up heat during the day and release it slowly at night. There aren’t many trees to provide shade or moisture. So, cities end up several degrees warmer than the forests…

Renewable Energy is Powering a Brighter Future
I know it’s hard to ignore the bad news right now. We’re seeing stronger heat waves, bigger wildfires, and oceans under stress. And on top of that, some political decisions feel like they’re pushing us backward instead of forward. But here’s something amazing: in 2025, something shifted—and you’re here to see it. The part that doesn’t always make the headlines? Renewable energy is moving ahead anyway—and it’s picking up speed. For the first time in history, the world added so much renewable energy that fossil fuels actually lost ground. Not just slowed down. Lost ground. Solar panels and wind turbines grew so fast that they supplied 99% of all the…

What’s Killing Gray Whales? (Hint: It’s Not Wind Energy)
Scientists are sounding the alarm about a gray whale crisis up and down the Pacific Coast. The culprits are well documented — and offshore wind isn’t one of them. San Francisco Bay is famous for its Golden Gate Bridge, its ferries, and its busy ports. But lately, locals have been noticing something new in those waters: gray whales. Huge, barnacle-covered, and beautiful — they’ve been showing up in growing numbers since 2018. Their arrival has brought both wonder and worry. People line the shores to watch them feed and swim. Researchers race to understand why so many of them are starving. And too often, the whales end up dead. In…

Red Flag Warning: Why Wildfires Are Everyone’s Problem Now
You’ve probably heard the phrase “red flag warning” lately. It might sound like complicated weather talk — but it’s actually a warning we all need to take seriously. A red flag warning means conditions are perfect for a wildfire to ignite quickly and spread even faster. All it takes is: One spark. That’s it. And suddenly, you have a wildfire. This isn’t just a hypothetical — it’s happening right now, across the country. In Georgia, fires are behaving in extreme ways: racing forward with the wind and hurling embers ahead of the flames, destroying homes and infrastructure in their path. As of April 25, 2026, a dangerous combination of severe…

Truth or Trickery? How to Tell Science from Propaganda
I spend way too much time on social media platforms. I often come across various forms of propaganda and disinformation, especially about climate change and renewable. Bots create some of these posts. Bad actors funded by billionaires and dirty energy produce others, and some come from people who genuinely can’t distinguish between science and propaganda. The Early Days of Propaganda in America Even though the word propaganda became popular in the United States around World War I, the idea behind it is much older. One of the first groups to use it were the ancient Greeks. They didn’t have printed ads or movies like we do today, but they still…

Earth’s Energy Imbalance: Why Our Planet Is Heating Up
Have you ever stepped outside on a sunny day (it’s 78 today where I live!) and felt the warmth of the Sun on your skin? That sunlight is energy—and it’s what keeps our planet livable. But here’s the problem: Earth is now taking in more energy than it sends back out to space. Scientists call this an energy imbalance, and it’s the main reason our planet is warming. Scientists have been tracking this imbalance since the late 1980s. But things really improved in 2000, when Terra satellite began collecting detailed data using NASA’s CERES instrument. That mission gave us the first long-term, high-accuracy global record of Earth’s energy imbalance. How…

Solar Breakthrough: More Energy from the Same Sunlight
Japanese and German scientists have made a big breakthrough in solar energy—and it could change how much power we get from the sun. Normally, solar panels follow a basic rule: one particle of light (called a photon) creates one unit of energy. Because of this, there’s been a “limit” on how efficient solar panels can be. In fact, they usually capture only a fraction of the sunlight that hits them. But now, researchers have found a way to go beyond that limit. They used a special process called singlet fission. This lets one particle of light split its energy into two usable energy packets instead of just one. To make…

Are Hair Products Safe? New Report Finds Cancer-Linked Ingredients
A new report raises serious concerns about cancer-linked ingredients in some hair products sold in stores like Sally Beauty. Researchers found that many of these products—especially those marketed to Black women and other women of color—may contain chemicals linked to cancer and other health problems. What Did the Researchers Find? Scientists tested hundreds of hair products made for curly, coily, and textured hair. These included things like hair relaxers, straightening creams, conditioners, and styling products. They discovered that many of these products contain toxic chemicals that can release formaldehyde, a substance known to cause cancer. Even when formaldehyde isn’t listed on the label, some ingredients can turn into it when…

California’s Next Megaflood May Be Closer Than You Think
Scientists like Daniel Swain are studying something called megafloods, which are really, really big floods that can last for weeks and cover large parts of a region with water. These aren’t normal floods from a thunderstorm — they’re massive events caused by long periods of extreme rain and storms. I decided to write about this after three powerful storms recently slammed parts of California. Some neighborhoods in Los Angeles even flooded. I went to college in LA and lived there from 2002 to 2022. In all those years, I never saw fires and floods like the ones we’re seeing now. The weather feels different — more intense, more extreme. It…

Big Changes Are Happening in a Very Salty Part of the Ocean
Scientists found that part of the southern Indian Ocean, the water off the west coast of Australia, is losing a lot of salt much faster than expected. Normally this area is one of the saltiest parts of the ocean, but now it’s getting fresher (less salty) very quickly — and that seems to be connected to climate change. You might ask, “Who cares?” Why Salt Matters in the Ocean Salt changes how heavy water is. This sinking and rising movement helps power giant ocean currents — sometimes called the ocean’s “conveyor belt.” These currents move heat and nutrients all around the planet. But now, research shows the salty region in…

Why AI Data Centers Need So Much Water
You’ve probably heard how fast artificial intelligence (AI) is growing — things like chatbots, smart apps, and online games all use powerful computers hidden inside data centers. These buildings are full of servers (big, fast computers) that help process all the information we send and get online. But what most people don’t think about is that these huge computer hubs need a LOT of water, and that’s causing real problems in places like Texas, Virginia, California, and Arizona. What Do Data Centers Actually Do? When you send a text, stream a video, ask an AI a question, or post a photo, it doesn’t just float around in the air. That…

Did You Know Penguins Live in Africa? Color One!
Did you know there are penguins in Africa? It surprises a lot of people—but it’s true! African penguins live along the coasts of South Africa and Namibia. And right now, these tuxedo-wearing birds are fighting for their lives. African penguins are facing a serious food crisis. Scientists and wildlife experts say many of them are starving because they simply can’t find enough fish to eat. This isn’t just a bad year—it’s part of a long-term problem that has pushed African penguins to the edge of extinction. In fact, African penguins are now listed as critically endangered, which means they could disappear forever if things don’t change soon.

The Energy Source That Never Sleeps: Geothermal
An exciting new study led by Mark Jacobson at Stanford University found that using geothermal energy—which is power from heat deep inside the Earth—could be a big help in moving the world toward clean, renewable energy. Geothermal energy works kind of like this: deep underground the rock is super hot, and we can turn that heat into electricity that doesn’t produce pollution. The cool thing is, it can run 24/7—even when the sun isn’t shining and the wind isn’t blowing. This study shows that if we add this underground heat energy to wind, solar, and batteries, we wouldn’t need as much land or as many big energy systems to make…

N2O – The Greenhouse Gas No One Talks About (But Should)
When people talk about climate change, two gases usually steal the spotlight: carbon dioxide (CO₂) and methane (CH₄). But there’s another greenhouse gas quietly heating up the planet—nitrous oxide (N₂O)—and most people hardly ever hear about it. I live in one of the most diverse and vibrant agricultural regions in the state. Here, winegrapes, olive trees, berries, and vegetables grow side by side, set against rolling green hills—at least in the winter. Farming is part of everyday life here. And that’s exactly why nitrous oxide matters so much. It’s closely tied to how we grow food, and even though it’s often overlooked, it packs a powerful climate punch. What Is…

Is the World Running Out of Fresh Water?
A new report from the United Nations (UN) warns that the world is running out of fresh water. The UN says we’ve entered a time called “water bankruptcy,” which means many places are under extreme water stress. Water stress happens when a community is using almost all the water it has—so there’s very little left to share. This often happens because water isn’t managed well, and climate change makes things worse by bringing longer droughts and less predictable rainfall. Many Big Cities Are Running Out of Fresh Water New research shows that about half of the world’s 100 biggest cities are running out of fresh water. That means places where…

The CO₂ Fingerprint: Proving Where Extra Carbon Comes From
If Earth had a detective story, carbon dioxide would be one of the biggest clues. Scientists know the amount of CO₂ in the air is rising—but the big question is why. Is it volcanoes? The ocean? Natural changes? Or is it us? It turns out carbon leaves behind a kind of fingerprint. By studying tiny differences inside carbon atoms, scientists can tell where that carbon came from. When they looked closely at the CO₂ building up in the atmosphere, the evidence pointed clearly in one direction: human activities, especially burning coal, oil, and gas. This carbon clue is called the Suess Effect, and it helps explain how scientists know the…
