The Carbon Cycle

The Carbon Cycle is the process by which carbon is constantly absorbed, stored and recycled by living and non-living things, thereby maintaining the delicate balance that supports all life on Earth.

Our Carbon Culture

For centuries, humans have relied on fossil fuels to power our world. Coal fuelled the Industrial Revolution but has also had a devastating impact on people and the natural environment. Let’s dig a little deeper into our use of coal.

Since the 1970s, our oceans have absorbed 90% of the excess heat produced by CO2 emissions. As our oceans get hotter, and sea levels continue to rise, our world is sure to look very different in the future.

Heatwaves caused by periods of extreme hot or dry weather are becoming more frequent across our planet. While some regions are able to cope with their devastating effects, others struggle to survive.

Adding to the Problem

Deforestation and the use of fossil fuels are not the only human activities causing climate change. Other aspects of modern life are adding to the problem by producing greenhouse gases, like methane, nitrous oxide and chlorofluorocarbons. Let’s examine where they come from.

By monitoring changes in C02 levels over thousands of years, scientists know that Earth’s temperature is rising. The biggest cause of global warming? Our reliance on harmful fossil fuels.

Fossil Fuels: Part Two

For centuries, humans have relied on fossil fuels to power our world. Oil and gas are hydrocarbons that have helped fuel our modern way of living, but burning them has a devastating impact on the natural world.

Burning the Forests

Trees and forests are known as the lungs of the Earth – because they absorb and store carbon. But when they’re burned or cut down, the C02 they release contributes to global warming.

The Greenhouse Effect

Earth’s atmosphere acts like a greenhouse, deflecting the fiercest of the Sun’s rays while retaining heat that would otherwise escape at night. This is known as the greenhouse effect and it’s a process that’s essential to life on Earth.
