Life on Earth has weathered boiling-hot oceans and volcanic-ash-darkened skies—but that’s nothing like the climate change we’re experiencing now. In this episode of Crash Course Biology, we’ll talk about the greenhouse effect, learn why...

If we’re going to send people to Mars someday, we’re going to need to be very conscious of the challenges presented in this endeavor. And at the top of that list is the ferocious nature of dust on the barren planet.

We already have the technology to bring humans safely to Mars and set up small settlements - or at least could do within a generation. But those settlements will need to be cocooned - shielded against the deadly cold, intense radiation,...

You’ve seen it in the comment section before: “Climate change is natural. It’s happened before and it will keep happening”. In reality, comments like these are the newest kind of climate change denial. In this video we’re going to learn...

In this video Paul Andersen explains how the greenhouse effect and greenhouse gases keep our planet warm enough to be habitable. He explains how greenhouse gases keep heat closer to the surface. He finally shows how increases in...

Do other planets have weather? It turns out that, yes, they do! But, the weather isn't all the same on other planets because of things like atmosphere. In this episode of Crash Course Kids, Sabrina takes us on a tour of the weather on...

Top climate scientist James Hansen tells the story of his involvement in the science of and debate over global climate change. In doing so he outlines the overwhelming evidence that change is happening and why that makes him deeply...

You’ve probably heard a lot about how climate change is affecting our planet, but did you know a warming climate also affects objects in space?

Venus is a gorgeous naked-eye planet, hanging like a diamond in the twilight -- but it’s beauty is best looked at from afar. Even though Mercury is closer to the sun, Venus is the hottest planet in the solar system, due to a runaway...

In this video Paul Andersen explains how the global climate is changing as a result of natural phenomenon and human actions. Changes in the solar radiation due to variations in the Earth's tilt and orbit have caused the ice ages. ...

There's a game of Tetris happening on a global scale: The playing space is planet Earth, and all those pesky, stacking blocks represent carbon dioxide -- a greenhouse gas that is piling up ever more rapidly as we burn the fossil fuels...

In this video Paul Andersen explains how matter and energy flow and cycle through systems. He starts by explaining how energy and matter input and output will always be conserved. He addresses the many misconceptions surround energy...

Scientists tend to be careful and resistant to big claims. So evidence for the possible end of the living world took a while to be seen as such. In this episode of Crash Course History of Science, Hank talks to us about where Climate...

In this video Paul Andersen describes both weather and climate. Weather is the day-to-day conditions on the Earth's surface, including temperature, wind, humidity, air pressure, and precipitation. Climate are the long term conditions...

In this video Paul Andersen explains how the climate on the earth is affected by the amount of solar radiation and the greenhouse affect. The addition of anthropogenic greenhouse gases has led to global warming which is impacting humans...

A video entitled "Polluting of the Atmosphere" which talks about the negative effects of pollution.

Pupil outcome: I can use my understanding of climate change to give a speech. Key learning points: - Climate change is driven by human activity - specifically, an increase in greenhouse gases. - Climate change will have significant...

Pupil outcome: I can make notes about deforestation in the Amazon rainforest and its links to climate change to answer an essay question. Key learning points: - Before we write an essay, we need to research the subject, making notes that...

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....

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,...
