Water being prevented from reaching the surface by trees or grass. It acts as a temporary storage.

Rainfall that reaches the ground directly, without being intercepted by vegetation.

Water flowing through the topsoil layer parallel to the surface, much slower than overland flow.

Water seeping downwards through the soil and rock layers.

Water flowing over the surface of the land.

A project to restore peatlands on Exmoor by blocking drainage ditches to increase water storage and reduce flooding.

Rock that does not allow water to pass through it easily.

Water soaking into the ground.

Deforestation reduces evapotranspiration, leading to less water vapor in the atmosphere. This results in decreased precipitation and a higher risk of drought. Additionally, soil erosion increases, leading to reduced water retention and local flooding.

A natural environment that absorbs more carbon dioxide from the atmosphere than it releases, helping to offset greenhouse gas emissions.

A natural system that releases more carbon dioxide into the atmosphere than it absorbs and stores.

A place where carbon is accumulated and stored. Major carbon stores include the lithosphere, hydrosphere, cryosphere, atmosphere, and biosphere.

The movement of carbon between different carbon stores.

The process where living organisms use sunlight, water, and carbon dioxide to create oxygen and glucose.

Deforestation disrupts the natural carbon cycle, leading to increased carbon dioxide in the atmosphere. This happens because trees act as carbon sinks, absorbing CO2 during photosynthesis. Removing trees reduces this absorption, contributing to climate change.

Deforestation reduces the amount of carbon stored in trees, releasing stored carbon back into the atmosphere. This contributes to global warming and climate change.

A visual representation of global temperature trends over the past 1000 years, showing a sharp upward trend starting in the late 20th century.

A carbon sink absorbs more carbon than it releases, while a carbon source releases more carbon than it absorbs.

The conversion of land from natural ecosystems to agricultural or urban areas, often resulting in increased carbon emissions.

Livestock, primarily cattle, contribute significantly to methane emissions through enteric fermentation (digestion).

Rice paddies, due to constant flooding, create a breeding ground for bacteria that produce large amounts of methane.

Activities like fertilizer use, manure management, and fossil fuel combustion contribute to nitrous oxide emissions.

Expanding farmland destroys natural ecosystems, negatively impacting local wildlife and biodiversity.

Cold water dissolves more CO2 than warm water. This means chemical processes, like those in the carbon cycle, are more active in colder areas.

When the ocean absorbs more CO2, it becomes more acidic. This harms marine life, particularly coral reefs, which can bleach and die.

As the Arctic and Antarctic warm, they can hold less CO2, potentially releasing it back into the atmosphere.

A warmer globe can lead to increased forest coverage in higher latitudes, increasing photosynthesis and respiration, potentially reducing atmospheric CO2.

Melting ice and snow contribute to runoff into oceans, carrying sediment that eventually forms deep ocean sediments and fossil fuels.

Melting permafrost across the Arctic releases methane and CO2, contributing to climate change.

Cold temperatures slow down decomposition, reducing the transfer of carbon from dead organisms to the atmosphere.

Wildfires, particularly long-lasting ones, release significant amounts of CO2 and other greenhouse gases into the atmosphere.

Over 600 million people live in coastal areas less than 10 meters above sea level, making them vulnerable to rising sea levels.

One-third of the world's coral reefs have died due to repeated heat stress, highlighting the impact of climate change on marine ecosystems.

The process of capturing waste CO2, transporting it to a storage site, and securely storing it underground to prevent its release into the atmosphere.

A CCS project in Canada aiming to capture 90% of a coal plant's CO2 output. However, it was expensive to build and consumes a significant portion of the plant's energy.

CCS can reduce carbon emissions, potentially lowering the costs of addressing climate change and creating jobs in the building and maintenance sectors.

The deliberate planting of trees, often in large numbers, to absorb carbon dioxide from the atmosphere.

Planting trees in areas where they were not previously present or were cleared allows for carbon storage and helps mitigate climate change.

The increasing acidity of ocean water due to the absorption of carbon dioxide from the atmosphere, which harms marine ecosystems and coastal communities.

Ocean acidification poses risks to coastal communities by affecting their food sources (reduced fish populations) and their ability to withstand rising sea levels (weakened coastlines).

The process of chemical weathering breaks down rocks, releasing carbon dioxide into the atmosphere. This carbon dioxide eventually gets absorbed into rainwater and oceans, contributing to ocean acidification.

Marine organisms like shellfish use carbon dioxide dissolved in seawater to form their shells. As ocean acidification increases, the availability of this carbon dioxide for shell growth decreases, impacting these creatures.

Rising global temperatures cause the Arctic ice to melt faster, leading to a decrease in reflective surfaces and increased heat absorption.

Melting ice leads to warmer water, which further melts the ice, creating a reinforcing loop that accelerates global warming.

Increased evaporation from warmer temperatures leads to more water vapor in the atmosphere, forming more clouds and reflecting more sunlight back into space, potentially cooling the Earth.

Feedback loops in the water cycle can amplify or dampen the effects of climate change. Positive feedback loops accelerate warming, while negative feedback loops can help moderate it.
