Examine the impact of deforestation on climate change. How does forest loss contribute to global warming, and what measures can be taken to address this issue?
s well as being stunningly beautiful, forests are vital for the health of our planet. They provide food and shelter for so much of life on Earth – from fungi and insects to tigers and elephants.

s well as being stunningly beautiful, forests are vital for the health of our planet. They provide food and shelter for so much of life on Earth – from fungi and insects to tigers and elephants.
More than half the world’s land-based plants and animals, and three-quarters of all birds, live in and around forests.
Forests have a big influence on rainfall patterns, water and soil quality and flood prevention too. Millions of people rely directly on forests as their home or for making a living.
But the risks from deforestation go even wider. Trees absorb and store carbon dioxide. If forests are cleared, or even disturbed, they release carbon dioxide and other greenhouse gases.
Forest loss and damage is the cause of around 10% of global warming. There’s simply no way we can fight the climate crisis if we don’t stop deforestation.
We need to protect forests now more than ever.

Deforestation has profound implications on local climate patterns and biodiversity. The removal of trees disrupts the water cycle and leading to decreased rainfall, which can cause droughts and alter local climate patterns. Without tree cover, soil erosion increases, and temperature extremes become more pronounced, exacerbating the heat island effect in surrounding areas. These changes can severely affect agriculture, water supplies, and the livelihoods of local communities. Biodiversity also suffers greatly from deforestation. Forests are home to countless species, many of which are endemic and cannot survive elsewhere. The loss of habitat leads to species decline and extinction, disrupting ecosystems and reducing the genetic diversity necessary for resilience against environmental changes. To make reforestation projects more effective, it is essential to focus on restoring native ecosystems rather than simply planting trees. Selecting diverse native species that are well-suited to local conditions ensures that the new forest can support a wide range of wildlife. Involving local communities in reforestation efforts can provide economic benefits and encourage long-term stewardship of the land. Additionally, combining reforestation with sustainable land management practices, such as agroforestry, can enhance biodiversity while supporting local agriculture. Monitoring and maintaining these projects are crucial for ensuring their success over time.

Deforestation significantly contributes to climate change through several mechanisms. When trees are cut down, they release the carbon dioxide (CO2) they have stored during their lifetime back into the atmosphere. This release increases the concentration of greenhouse gases, which trap heat and lead to global warming. Forests act as carbon sinks, absorbing CO2 from the atmosphere. The reduction of forests diminishes this natural carbon absorption capacity, exacerbating the accumulation of greenhouse gases.

The removal of trees disrupts these patterns, potentially causing shifts in weather conditions and contributing to regional and global climate changes. Trees also release water vapor into the atmosphere through transpiration, which helps form clouds and promotes rainfall. Deforestation reduces this process, potentially leading to decreased rainfall and increased risk of droughts.
Additionally, forests protect soil from erosion by stabilizing the ground with their root systems. When trees are removed, soil erosion increases, releasing more stored carbon into the atmosphere. The loss of forest cover also increases the land’s albedo, or reflectivity, which can affect local climate by reflecting more sunlight back into space. These combined effects make deforestation a critical driver of climate change.
