As 2025 wraps up (even though it feels like it just started!), here’s a quick update on global greenhouse gas emissions. Sadly, the news isn’t great—our three biggest heat-trapping gases are still risi Carbon Dioxide (CO2) Emissions Image: CO2 in the air from the Mauna Loa Observatory.

Scientists predict that 2025 will be the second or third warmest year on record. We’re emitting more CO2 every year, so why won’t this year be warmer than last year? Even though Earth is warming over the long run, not every single year will be warmer than the one before it. That’s because natural climate patterns, like El Niño and …

Have you ever noticed how bright our planet looks from space? Earth usually reflects sunlight like a giant blue-and-white mirror. But scientists have discovered something surprising: Earth is losing it's shine and is actually getting dimmer. What “Getting Dimmer” Means Our planet has a property called albedo, which is the fraction of sunlight that gets bounced back into space. Earth …

Since about 2006, methane levels in Earth’s atmosphere have been climbing fast — mostly because of human activities. It is a super-powerful greenhouse gas that traps heat, but it doesn’t last as long in the air as carbon dioxide does. It's also the second-largest contributor to rising global temperatures after carbon dioxide (CO₂). It’s already added about half a degree …

https://www.nature.com/articles/s43247-025-02768-2As our planet heats up, the Arctic is getting greener. I just read an interesting study about how all those new plants—especially shrubs—could be changing what’s going on underground in the frozen soils known as permafrost. For four years, scientists in northern Greenland ran an experiment to see what happens when frozen soil is exposed to air and mixed with …

Under the ocean’s surface, there’s an underwater symphony. Blue whales and other marine mammals fill the water with songs and calls, almost like an underwater orchestra. To eavesdrop on this symphony, scientists use special tools called hydrophones — microphones designed to work underwater. In this case, researchers used a hydrophone anchored 3,000 feet below the surface. What Did the Scientists …

Imagine this: you’re walking across the frozen tundra in Siberia and—whoa—there’s a giant hole in the ground, big enough to swallow a house. No, it’s not a scene from a sci-fi movie. These craters are real, and scientists have been finding more of them over the past decade. The big question: what’s going on? What’s Hiding Under the Ice? Siberia …

As a scuba diver, I’ve seen the wonders of the undersea world—brilliant coral reefs, swaying seagrass meadows, and the incredible creatures that call these places home. That’s why what happens with bottom trawling feels so devastating. Picture this: a huge fishing boat drags a massive, weighted net across the seafloor. It tears through everything in its path, scooping up fish. …

In August, Hurricane Erin tore across the Atlantic Ocean with winds blasting over 160 miles per hour on August 16. Erin didn't make landfall, but its effects—big waves, riptides, and rough weather—slammed coastal communities. This created dangerous conditions stretching over 1,000 miles of the East Coast. And here’s the kicker: climate change is making those effects worse. Supercharged: Hurricane Erin’s …

In Arizona, the summer heat has turned deadly. Public health officials warn that extreme temperatures in Maricopa County may have already claimed more than 400 lives. Across the ocean, Southern Europe is also in crisis, with heatwaves fueling wildfires—including 152 new blazes in Greece alone. Far to the north, Alaska faced a very different kind of disaster. A lake of …

August 13, 2025 Floods aren’t just breaking records—they’re breaking lives. Picture this: streets turned into raging rivers, rooftops barely peeking above swirling brown water, and rescue boats zigzagging through what used to be quiet neighborhoods. Right now, parts of the Midwest are drowning. Not long ago, New York City’s subways became underground lakes. Last month, Beijing was hammered with a …

We're used to hearing about floods and wildfires, but there's a great deal of climate change happening beneath the surface. You've likely heard about ocean acidification and coral bleaching, but there's so much more we just can't see. On a small research boat in Chesapeake Bay, a scientist collected water to study tiny living things called microbes. All around, people …

Special thanks to Jay Thompson for his contribution to this blog! Vanishing insects are the silent alarm of climate change—one we can’t afford to ignore. Image: Pademelon at the door of my cabin Credit: Susan Callery Some of my most cherished memories come from forests, such as the rainforests of Borneo, or in Tasmania where I was greeted by a …

Every year, Earth’s temperature changes a little. Sometimes it gets hotter, and sometimes cooler. Scientists track this closely to understand how our climate is changing. But it’s not just about climate change. Natural patterns in the ocean also affect short-term global temperatures. Two of the biggest ones are called El Niño and La Niña. These are part of a system …

Vanishing clouds? Why should we care? We usually think of clouds as just part of the weather—something that blocks the sun, brings rain, or makes cool shapes in the sky. But did you know that clouds also help protect our planet from getting too hot? A new study shows that certain types of clouds are disappearing, and that’s bad news …

The world’s major farming regions—places like the California and the Midwest in the U.S. and parts of Asia and Africa—are heating up. These areas grow the foods we depend on most, like wheat, corn, and rice. But climate change is making it harder for these crops to survive. In fact, scientists say we’re already seeing smaller harvests in some places. …

We hear the most about carbon dioxide (CO2) because it's the main greenhouse gas causing climate change. Most of the CO2 comes from burning fossil fuels like coal, oil, and gas for things like electricity, cars, and factories. Since humans produce so much of it every day, CO2 has the biggest long-term impact on Earth's temperature. That's why people talk …

Alarming Forecast: The World Meteorological Organization (WMO) is a group that studies Earth’s weather and climate. They just released a new report that looks at what Earth’s climate might be like from 2025 to 2029, and it's scary! This report, called the Global Annual to Decadal Climate Update, is something they publish regularly to help us understand what’s coming in …

Wildfires are becoming more common and intense, and human-caused climate change is a big reason why. Here's a simple explanation of how climate change fuels wildfires. 🔥 Why Are Wildfires Getting Worse? As the Earth's climate warms, certain areas experience hotter, drier conditions and thirstier air. This dries out trees, plants, and grass, making them more likely to catch fire. …
