Why Cities Feel Hotter Every Summer (It’s Not Just You)

Cities trap heat like giant concrete ovens. Roads, buildings, car parks, rooftops... they soak up sunlight during the day and release it slowly through the night. Nature, which would normally cool things down, gets kicked to the curb: trees are replaced with asphalt, grass becomes cement, and shady spots vanish behind reflective windows.



This creates what scientists call “urban heat islands”, areas where temperatures can be 5–10°C warmer than nearby suburbs. That’s why strolling through a city in summer can feel like stepping into a giant hair dryer. Your ice cream melts faster, your shirt sticks to your back, and even the breeze seems to sigh, “Not today, buddy.”

But it’s not just about the materials. Cities are crowded with energy. Air conditioners, cars, buses, and factories all pump out extra heat. Think of it as a city-wide human-generated sauna effect. Add the lack of vegetation, and you get a recipe for sizzling sidewalks and overheated metro stations.

And the problem is getting worse. Each summer, heatwaves creep earlier and linger longer, hitting cities harder than their leafy neighbors. It’s not a coincidence that densely built-up areas are hotspots, it’s physics and city design teaming up against you.



So what’s the secret to cooling our concrete jungles? More plants, please! Trees, parks, and green roofs act like nature’s air conditioning. They provide shade, store water, and evaporate moisture, which cools the surrounding air. Even small patches of greenery can make a surprising difference. Water features, rooftop gardens, and reflective surfaces also help by reducing heat absorption.



Heatwaves aren’t just weather events; they’re design problems. And while we can’t move entire cities into the Arctic, we can rethink how we build them. Planting more trees, replacing asphalt with porous surfaces, and designing buildings to work with the sun rather than against it, these aren’t just landscaping choices; they’re survival strategies for summer in the city.

So next time you’re sweating on the sidewalk, remember: it’s not just your imagination. The city is literally cooking you! With a few clever tweaks, we can turn the urban oven back into a livable, leafy oasis.

The Ocean Is Basically a Giant Lung System (But Slimier)

Image
 When we think about the ocean, most of us picture blue waves, whales doing their dramatic tail flips, and maybe the occasional manta ray gliding by like it owns the place. But the ocean isn’t just a giant aquarium, it’s a breathing, living system that quietly keeps us alive. And yes, you could think of it like Earth’s lungs… if lungs were slimy, salty, and full of sea cucumbers. The Ocean Makes the Air We Breathe (Literally) Here’s something most people don’t realise: more than half of the oxygen we breathe doesn’t come from forests, rainforests, it comes from phytoplankton which are  microscopic marine plants that live near the surface of the ocean. These tiny green powerhouses perform photosynthesis just like land plants: They absorb sunlight They take in carbon dioxide They release oxygen But they do it on such a massive scale that every second breath you take is basically sponsored by plankton. They’re the unsung heroes of life on Earth, doing billions of...

Victoria’s Bushfires: Loss, Grief, and How We Can Help

Victoria’s bushfires are more than just headlines or statistics. I really want to emphasis that it is about homes reduced to ash, ecosystems destroyed in hours, and communities left grieving what can never be replaced. Every fire season, the devastation feels heavier, and the reality of climate change feels closer to home. Bushfires displace wildlife and eat away at habitats that take decades to grow. This loss of habitat leave lasting scars on land and people alike. Native animals suffer immense loss where many don’t escape. The ones that are lucky enough end up facing starvation and a loss of home alike. For communities, the emotional toll is just as significant as the physical damage. Families lose homes, livelihoods, and a sense of safety. It is naive of people to think that recovery happens within months or years, starting from zero is not a joke, and the reality of the situation requires all of our deepest sympathies and support. Why This Keeps Happening Hotter temperatures, prol...
