Climate change refers to long-term shifts in temperatures and weather patterns. These changes can be natural, resulting from variations in the sun’s activity or large volcanic eruptions. However, since the 1800s, human activities—primarily the burning of fossil fuels like coal, oil, and gas—have become the main driver of climate change. The impact includes alterations in Earth’s local, regional, and global climates, affecting everything from average temperatures to extreme weather events.

The major contributors are

1.Greenhouse Gases (GHGs):

• Carbon Dioxide (CO₂): Released from burning fossil fuels and deforestation.
• Methane (CH₄): From livestock, landfills, and fossil fuel production.
• Nitrous Oxide (N₂O): Emitted during fertilizer use and fossil fuel burning.
• Chlorofluorocarbons (CFCs): Industrial compounds (now regulated).
• Water Vapor

2. Industrialized Nations

Industrialized nations are defined as places where a large portion of the gross domestic product and exports comes from industrial production. 

3.Land Use (deforestation, urbanization, agriculture)

All throughout human history, we have subjugated natural lands to our own purposes. Forests cover around 31% of the world and hold more than 80% of the world’s terrestrial species; however, humans are decreasing the amount of forested land and, consequently, the biodiversity housed there.

4.Waste

In a world of mass production, humans produce more waste than we know what to do with.

Around the world, about 30% of total food production is wasted either before or after it reaches its consumers. Around 2 billion tons of municipal solid waste is generated globally every year.

International Measures:

• Paris Agreement: Adopted in 2015, aims to limit global warming to well below 2°C (preferably 1.5°C). Countries committed to emission reduction and adaptation efforts.
• Sustainable Development Goals (SDGs): Goal 13 focuses on climate action, intrinsically linked to other SDGs.
• IPCC Reports: Provide assessments and guidance for mitigation efforts.
• Renewable Energy Transition: Shift to cleaner energy sources.
• Global Cooperation: Coordinated efforts to address emissions worldwide.

climate change results from human activities that release greenhouse gases (GHGs) into the atmosphere. Major contributors include carbon dioxide (CO₂) from fossil fuels, methane (CH₄) from livestock and landfills, and nitrous oxide (N₂O) from agriculture. International efforts, such as the Paris Agreement, aim to limit global warming, transition to renewable energy, and promote global cooperation. Let’s work together to protect our planet!

Deforestation occurs when forests are converted to non-forest uses, such as agriculture and road construction. It leads to the long-term loss of forest area. In contrast, forest degradation doesn’t reduce the forest area but rather results in a qualitative decline in forest condition. Forest ecosystems lose their capacity to provide essential goods and services to people and nature during degradation. These threats jeopardize the critical role forests play in purifying water, mitigating climate change, and supporting biodiversity.

Local Impacts:

• Loss of Biodiversity: Deforestation disrupts habitats, leading to the loss of plant and animal species. Many species rely on specific forest ecosystems for survival.
• Changes in Water Cycle: Healthy forests play a vital role in the local water cycle by creating rainfall. When deforestation occurs, forests are less capable of fulfilling this role, resulting in changes in precipitation and river flow¹.
• Soil Erosion: Tree roots stabilize soil, preventing erosion. Without trees, soil becomes vulnerable to erosion, affecting local agriculture and water quality.
• Temperature and Rainfall Changes: Deforestation, especially in tropical regions, impacts local temperatures and rainfall. These changes can compound the effects of global climate change, affecting human health and agricultural productivity.

Global Impacts

• Climate Change: Almost 17.4% of global greenhouse gas emissions result from deforestation and forest degradation. Trees store carbon, and excessive deforestation releases this carbon into the atmosphere, contributing to global warming and climate change.
• Carbon Sink Loss: Forests act as carbon sinks, absorbing carbon dioxide. Deforestation reduces this capacity, exacerbating climate change.
• Altered Weather Patterns: Deforestation affects weather patterns globally, impacting rainfall distribution and temperature regulation.
• Loss of Ecosystem Services: Forests provide essential services like air and water purification, nutrient cycling, and pollination. Their loss affects global ecosystems and human well-being.

Governments can provide policies and regulations that promote sustainable forestry practices and penalize companies that engage in deforestation.Efforts to combat deforestation include responsible forest management, reforestation, and sustainable land use practices. Protecting forests is crucial for a healthy planet and the well-being of all living beings.
