What is Climate Change?
Climate change refers to long-term shifts in weather patterns and average temperatures on Earth. It is primarily driven by human activities such as the burning of fossil fuels, deforestation, and industrial processes that release greenhouse gases into the atmosphere. These greenhouse gases, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), trap heat from the sun and cause the planet to warm up.
Causes of Climate Change
1. Greenhouse Gas Emissions: The burning of fossil fuels for energy, transportation, and industrial processes releases CO2 and other greenhouse gases into the atmosphere.
2. Deforestation: The clearing of forests reduces the number of trees that can absorb CO2 from the atmosphere, leading to increased levels of greenhouse gases.
3. Agricultural Practices: Farming activities such as rice cultivation and livestock farming produce methane, contributing to climate change.
4. Industrial Processes: Certain industrial activities release potent greenhouse gases like fluorinated gases, contributing to the warming of the planet.
Effects of Climate Change
1. Rising Temperatures: Global average temperatures are increasing, leading to heatwaves and changes in weather patterns.
2. Extreme Weather Events: Climate change is linked to more frequent and severe weather events such as hurricanes, droughts, and floods.
3. Sea-Level Rise: Melting ice caps and glaciers contribute to rising sea levels, posing a threat to coastal communities.
4. Ecological Impact: Changes in temperature and precipitation patterns can disrupt ecosystems and threaten the survival of plant and animal species.
