This Catalyst article examines the differences between fossil fuels and biofuels. At present, fossil fuels are used to provide most of our global energy requirements. Fossil fuels are a finite resource as they take millions of years to form and the remaining supplies are being used at a greater rate than can be...

In this podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC), reporters find out how satellites have revolutionised our understanding of climate change.

They provide a completely different perspective on how planet Earth works, which was impossible before the...

This Catalyst article explains how artificial photosynthesis could provide a useful energy supply and reduce the amount of carbon dioxide in the atmosphere. Experiments are underway in labs around the world. The aim is to use the basis of Photosynthesis to recycle the huge amounts of Carbon Dioxide being emitted...

A Catalyst article explaining how carbon capture and storage can reduce the amount of carbon dioxide entering the atmosphere and may reduce the effects of climate change. Burning fossil fuels releases carbon dioxide into the atmosphere. This is a major contributor to climate change but can CO2 be captured and...

A Catalyst article about carbon dioxide which can be used as a solvent in industry, or as a regulator of blood pH. This article looks at some other uses of carbon dioxide and considers its importance in global warming. It also explains how the greenhouse effect is a natural part of the operation of the Earth's...

This simulation can be used to explore how light interacts with molecules in our atmosphere.

Sample learning objectives include:

*Explore how light interacts with molecules in our atmosphere

*Identify that absorption of light depends on the molecule and the type of light

*Relate the...

A Catalyst article investigating what nitrogen and its compounds are used for. Nitrogen is colourless, odourless, non-toxic and inert, and has a wide range of uses. Nitrogen makes up seventy eight per cent of the Earth’s atmosphere by volume and has a considerable influence on respiration in plants and animals. The...

In this podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC), two researchers talk about the technological solutions some scientists say might have to be used to tackle climate change.

With average temperatures expected to rise by 2°C this century, and efforts...

Aerospace engineers need to take into account the heat generated when the space craft move through the atmosphere at extreme speeds, both during launch and at re-entry, as without proper thermal protection the space craft could be destroyed. Insulating blankets, foams and tiles are used to protect the spacecraft....

These resources from NASA look at why telescopes are put into space. Students build simple spectroscopes and telescopes to learn the answer to this question. This educator guide is divided into units of study that include science demonstrations, lesson plans and student sheets so that students may learn about Earth...

These resources, provided by University of Liverpool, focus on the rise in Carbon Dioxide levels in the atmosphere over time.

Further information can be obtained from the Youtube site OceanClimateatUoL site, hosting other videos from Andy Heath and Ric Williams from University of Liverpool.

This collection contains a selection of videos relating to themes concerning climate change.

The first collection focuses on the rise in Carbon Dioxide levels in the atmosphere over time. The second resource offers three perspectives on...
