Today we’re going to talk about climate change which is when there is a change in the average weather patterns in a region over a long period of time - these changes can be natural or human-caused. We’ll discuss the main driving forces...

What we know today about global greenhouse gas emissions is mostly self-reported by countries, and those numbers (sometimes tallied manually on paper!) are often inaccurate and prone to manipulation. If we really want to get serious...

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. ...

Meter is the standard unit of length used by most countries around the world. But how did they define it?

As the Earth's surface temperature gradually rises, it has become vital for us to predict the rate of this increase with as much precision as possible. In order to do that, scientists need to understand more about aerosols and clouds....

As we keep pumping carbon dioxide into the atmosphere, more of it is dissolving in the oceans, leading to drastic changes in the water's chemistry. Triona McGrath researches this process, known as ocean acidification, and in this talk...

Pupil outcome: I can describe ways in which food systems contribute to climate change and investigate possible actions that can be taken to reduce the carbon footprint of food. Key learning points: - Farming and food production are major...

Pupil outcome: I can understand how the biosphere regulates the atmosphere and provides important environmental services. Key learning points: - The biosphere regulates the composition of the atmosphere. - The biosphere maintains soil...

Pupil outcome: I can understand how natural changes and human activities affect the balance of small-scale ecosystems. Key learning points: - Ecosystems are finely balanced and can be affected by changing one component. - College Lake is...

The term climate change is used to denote the long-term changes in the weather patterns in a given region. Another term often interchanged with climate change is global warming. Global warming is formally defined as a rise in Earth's...

Explore the escalating threat of forest fires exacerbated by climate change. Learn how rising temperatures, reduced rainfall, and prolonged droughts contribute to increasingly severe fire seasons. Discover the role of human activities...

Learn how the enhanced greenhouse effect, driven by human activities, leads to global climate change. Delve into the role of greenhouse gases like carbon dioxide and methane in trapping more heat in the atmosphere, and discover the...

Discover how increasing urbanization and industrial activity contribute to air pollution and its harmful effects on ecosystems. Learn about the damaging consequences of smog on plant species like the Ponderosa pine and the broader...

Explore the consequences of human activities like deforestation and the resulting strain on our planet's ecosystems and wildlife. Discover how our increasing population and resource demands alter landscapes and contribute to the...

This video explores five fun facts about avalanches.

It classifies pollutants based on different criteria and explains the type of hazard that they cause.

The video discusses the importance of biodiversity, which is the variety of all the different species of organisms on Earth or within an ecosystem. It explains how human activities such as waste management, deforestation, and global...

The video is a lecture presentation on the human impacts on biodiversity. The presenter discusses how common human activities, such as fishing and farming, can have unforeseen consequences that reduce biodiversity. They explain the...

A news feature from NASA’s Ames Research Center in Silicon Valley originally posted on August 24, 2016.

In this program, learn all about forests as ecosystems and their vital role for humankind. Understand how and why climate change is occurring, its role in the dramatic increase in forest fires, and how it threatens not only the survival...

This segment provides an introduction to aerosols- their varied sources, brief lifetimes, and erratic behavior. Glory's APS will help researchers determine the global distribution of aerosol particles. This unique instrument will...

COVID-19 led to changes in human activities around the globe. Some bodies of water have run clearer, emissions of pollutants have temporarily declined, and transportation and shipment of goods have decreased. We can see...

By most accounts, 2020 has been a rough year for the planet. It was the warmest year on record, just barely exceeding the record set in 2016 by less than a tenth of a degree according to NASA’s analysis....

The term climate change is used to denote the long-term changes in the weather patterns in a given region. Another term often interchanged with climate change is global warming. Global warming is formally defined as a rise in Earth's...
