whats is climate change?

What is Climate change

• Climate change is the long-term alteration of Earth’s climate patterns caused mainly by human activities

• Can affect the biophysical and anthropogenic systems, leading to significant environmental, economic, and social impacts.

how does land cover change such as deforestation for cattle grazing contribut to climate change?

Land cover change, particularly deforestation for cattle grazing, contributes to climate change by reducing the number of trees that absorb carbon dioxide, a key greenhouse gas. This loss of forest cover not only increases atmospheric CO2 levels but also disrupts local and global climate patterns.

explain the role of the amazon rainforest as a carbon sink and what happens when this function is lost.

The Amazon rainforest acts as a major carbon sink by absorbing large amounts of carbon dioxide through photosynthesis, helping regulate Earth’s climate. When deforestation or degredation occurs, this ability is lost, releasing stores carbon, increasing greenhouse gas levels, and increasing global warming and climate change.

What are coastal wetlands and why are they important?

Coastal Wetlands are ecosystems found where land meets the sea, inlcuding magroves, salt marshes, sea grass and meadows. they are important since they store carbon, protect shorelines from erosion and storms, filter pollutants, and provide critical habitats for diverse species, supporting biodiversity and maintaining healthy coastal enviorments.

what is biophysical

Biophysical refers to the physical and biological components of the Earth's systems, such as the atmosphere, oceans, land, and ecosystems, and their interactions.

what is anthropogenic

Anthropogenic refers to effects or processes that are caused or influenced by human activities.

What role do mangrove forests play in protecting the coastal wetland ecosystems, and what factors are currently threatening their existence?

• It protects coastal wetlands by stabilising shorelines, reducing erosion, filtering pollutants and providing habitats for marine life. They can store large amounts of Carbon.

• They are threatened by deforestation, coastal development, pollution, agricultural expansion, and rising sea levels caused by climate change, leading to habitat loss and degradation.
