Typically, with any piece of technology, you pump one unit of energy in and you get about one out. That’s just the first law of thermodynamics: energy has to be conserved. But there’s a piece of technology called a heat pump, where for...

What's it like keeping the lights on during war? Ukrainian energy executive Maxim Timchenko shares how his company has diversified Ukraine's power structures to survive Russian attacks, highlighting the resilience of renewable energy....

If a tree falls into the forest and doesn't decompose, what happens to it?

Oceanographer Penny Chisholm introduces us to an amazing little being: Prochlorococcus, the most abundant photosynthetic species on the planet. A marine microbe that has existed for millions of years, Prochlorococcus wasn't discovered...

Throughout Earth's history, climate has varied greatly. For hundreds of millions of years, the planet had no polar ice caps. Without this ice, the sea level was 70 meters higher. At the other extreme, about 700 million years ago, Earth...

Plastic is an incredible substance for the economy -- and the worst substance possible for the environment, says entrepreneur Andrew Forrest. In a conversation meant to spark debate, Forrest and head of TED Chris Anderson discuss an...

Imagine the hottest day you've ever experienced. Now imagine it's six, 10 or 12 degrees hotter. According to climate researcher Alice Bows-Larkin, that's the type of future in store for us if we don't significantly cut our greenhouse gas...

Huge container ships relying on fossil fuels transport all kinds of goods across the ocean, creating a huge climate change impact. But there's a better way to power this transport using, of all things, water.

Concrete sucks CO2 out of the atmosphere, but making it initially produces a lot of carbon dioxide as a byproduct. Fortunately, by rethinking the chemistry of cement altogether, we can actually use carbon dioxide to create our concrete...

Hank talks about the last major way humans are impacting the environment in this penultimate episode of Crash Course Ecology. Pollution takes many forms - from the simplest piece of litter to the more complex endocrine distruptors - and...

Pupil outcome: I can reflect on the importance of electricity in my life and I can record how I use it for everyday activities. Key learning points: - Most electricity is produced in power stations and then cables deliver the energy to...

Pupil outcome: I can identify the logical argument of an essay and I can identify an essay's linguistic features in a model. Key learning points: - Essays can either examine both sides of an issue in a balanced way, or they can argue...

Pupil outcome: I can explain what a carbon footprint is and how we can reduce it. Key learning points: - Carbon dioxide and other greenhouse gases trap heat in the atmosphere, leading to warmer temperatures on Earth. - A carbon footprint...

Climate scientists are clear that we need to reach net zero carbon emissions by 2050. And in order to do this, we’re going to need to electrify everything and green the grid. But what will this clean, green future look like? Can we pull...

We’ve all heard that we should keep global climate change under 2 degrees of warming, but did you know that there are many places around the globe that have already surpassed that? Some places around the globe are experiencing extreme...

Arctic air is warming, causing scientists to worry that melting arctic ice and snow could also lead to a sudden permafrost thaw and release of carbon dioxide (CO2) and methane (CH4) that forms a climate tipping point or feedback loop....

Remember the 2008 Financial Crisis? Experts warn that the same thing may be happening again, but this time, CLIMATE CHANGE is the culprit. Increasing natural hazards, from wildfires and hurricanes to rising sea levels and catastrophic...

For this episode we wanted to see where we are in terms of “business as usual,” and if we are still headed towards an apocalypse of sorts. Or if, perhaps, all of the technological innovations in renewables and EVs along with new climate...

Climate Change is increasing the frequency and severity of natural disasters all around the world. And in the United States, more and more people seem to be moving to the places that are projected to be most impacted by climate change,...
