Earth’s ice might seem far away—at the top of the world or high on a mountain—but it quietly helps keep Earth livable. Frozen oceans reflect sunlight, glaciers store freshwater, and icy ground holds ancient carbon in place. Together, these frozen parts of our planet are called the cryosphere, and they act like Earth’s natural air conditioner. As 2025 comes to an end, scientists are taking a hard look at how that system is doing. The answer is sobering. From shrinking sea ice at the poles to retreating glaciers and thawing permafrost, Earth’s ice is changing faster than expected. What’s happening in these frozen places doesn’t stay there—it affects sea level,…

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 has been losing its shine for decades, reflecting less light back into space—and the amount of light reflected by the Northern Hemisphere is decreasing more quickly than that of the Southern Hemisphere, recent research suggests. For a long time, scientists believed both hemispheres reflected roughly the same amount of light.…

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 dead plant bits, called litter. They were trying to picture what the Arctic might look like as plants keep spreading north. The results were pretty wild: that extra plant material actually changed the DNA of the tiny microbes living in the soil! Those microbes got busier—and hungrier—breaking down old carbon…

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 Find? Over six years, researchers from the Monterey Bay Aquarium noticed something troubling along the California Coast. Blue whales and fin whales began singing less often when the ocean got unusually warm. Scientists say the silence is a serious warning. Meanwhile, some whales that eat lots of different things (like…

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 is covered in permafrost, soil that usually stays frozen solid all year long. But, as the planet heats up, permafrost is thawing faster than ever. That’s already causing big problems you can see—like sinkholes opening up, telephone poles leaning, roads and runways cracking, and forests where trees just topple over.…

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. At the same time, it crushes coral reefs, seagrass meadows, and habitats that have taken centuries to grow. Behind it, clouds of dark mud swirl like an underwater storm. Even stingrays and baby sharks get trapped, with no chance of escape. This method, called bottom trawling, is one of the…

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 Shocking Rapid Intensification Erin exploded from a Category 1 storm to a monster Category 5 in less than a day—one of the fastest growth spurts ever recorded. Scientists say this kind of rapid jump is happening more often as our planet heats up. Jim Kossin, a former hurricane expert at…

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 rainwater and melting snow burst through a glacial dam near Juneau, unleashing a torrent that pushed the Mendenhall River to its highest level ever recorded. Streets and homes in the city were swallowed by the flood. Recent heavy rains caused sudden flash floods in Pakistan, killing 337 people. Since late…

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 year’s worth of rain in just days, killing 38 people. In Texas, massive floods claimed 119 lives. And now, Tennessee is under siege from rising water—where one family’s life ended in an instant when flood-loosened trees came crashing down on their car. Torrential rains swamped homes and roads across Mexico…

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 were enjoying the beach, unaware that dangerous bacteria called Vibrio were hiding in the water. Vibrio live naturally in oceans and rivers. Some types are harmless and even help the environment by recycling nutrients. But others can make people very sick—with symptoms like stomach cramps, diarrhea, or in rare cases,…

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. Some of my most cherished memories come from forests, such as the rainforests of Borneo, or in Tasmania where I was greeted by a curious pademelon at the entrance of my log cabin. In the Amazon rainforest I watched wild macaw parrots gather at clay licks — a vibrantly colorful and magical sight I wish everyone could experience. In nearly any forest on Earth, the productions of nature saturate our senses: the smell of moist ground and humid air, the sounds of birdsong, of tree…

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 for our warming world. What’s Happening? Scientists studied 20 years of satellite data to learn how clouds are changing. They found that the thick, low clouds that form over the ocean are shrinking. These clouds are important because they reflect sunlight back into space—kind of like a giant mirror. When…

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 about it the most. We just reached 430 ppm CO2, a more than 50% increase since 1750. CO2 levels haven’t been this high in millions of years. That’s way before humans—or even most of the animals and plants we know today—existed. That’s a big warning sign for our planet. Don’t…

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 the next few years. It uses powerful computer models to predict both long-term climate changes caused by things like greenhouse gas emissions and short-term natural patterns like El Niño, La Niña, and ocean cycles like the Atlantic Multidecadal Variability (AMV). What Does the Forecast Predict? 1. Super-hot years are probably…

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. When a fire starts—due to lightning, human activity, or other causes—it can spread quickly and become harder to control. In fact, fire seasons are lasting longer and happening more often than they used to. Wildfires and Climate Change: A Two-Way Street Wildfires aren’t just caused by climate change—they can make…

Climate change is making it easier for diseases spread by insects, like mosquitoes and ticks, to affect more people around the world. As temperatures rise and weather patterns change, these insects can live in more places and for longer periods. Now we’re seeing a surrge of insect-related diseases. What Are Insect-Related Diseases? Insect-related, known as vector-borne, diseases are are illnesses transmitted to humans through carriers like mosquitoes and ticks. These carriers, or “vectors,” pick up harmful germs from one host and pass them to another. Examples include: Malaria Dengue fever Zika virus Chikungunya Yellow fever These diseases are responsible for over 700,000 deaths each year and make up more than…

In 2024, scientists saw the biggest jump in carbon dioxide (CO₂) levels in Earth’s air since they started keeping track back in 1958. CO₂ went up by 3.58 parts per million compared to 2023, beating the old record from 2016. Nature couldn’t keep up. Most of this rise came from burning fossil fuels like coal, oil, and gas. On top of that, natural events like El Niño and massive wildfires in North and South America made things worse. We know all this from something called the Keeling Curve—a graph that shows how CO₂ levels have changed over time. It’s named after Charles David Keeling, the scientist who started measuring CO₂…

Glaciers on the Brink: Imagine a world where the towering glaciers, nature’s ancient water reservoirs, are on the brink of vanishing before our eyes. This isn’t a scene from a science fiction movie—it’s our current reality. What Are Glaciers and Why Do They Matter? Glaciers are like giant frozen libraries! They contain all kinds of important information about Earth’s past.  They are massive, slow-moving rivers of ice found in mountain regions and polar areas that store about 70% of the world’s freshwater. They also hold clues about past climate, how Earth has changed over time, and they even preserve plants, animals, and microorganisms that are really old. As they melt…

More than half the people in the world eat rice every day. But now, rising carbon dioxide and hotter temperatures are creating toxic rice. Global Hunger in Focus The world is already facing a huge hunger crisis. Right now, about 1.9 million people are experiencing extreme hunger, mostly in places like Gaza and Sudan, but also in parts of Sudan, Haiti, Mali, and parts of the Middle East. These people are very close to famine, which means not having enough food to survive. In one camp in northern Sudan, famine is already happening. Many of these hunger emergencies are getting worse each year because of many problems happening at the…
