Definition of Climate Change:
Climate change refers to significant and lasting alterations in Earth's climate patterns, including changes in temperature, precipitation, and extreme weather events. It's primarily driven by human activities that release greenhouse gases (GHGs) into the atmosphere, trapping heat and leading to global warming.
Causes of Climate Change:
Greenhouse Gas Emissions
Burning fossil fuels (coal, oil, and natural gas) for energy, deforestation, industrial processes, and agriculture contributes to increased carbon dioxide, methane, and nitrous oxide emissions.
Land Use Changes
Land use changes, like deforestation and urbanization, disrupt the balance of gases in the air. They reduce the Earth's ability to absorb carbon dioxide and can release potent greenhouse gases, contributing to global warming and climate change.
Waste Management
Improper waste disposal and decomposition release methane, adding to greenhouse gas concentrations.
Effects of Climate Change:
Rising Temperatures:
Global average temperatures have increased, leading to heatwaves and altered weather patterns.
Extreme Weather Events:
More frequent and intense storms, floods, droughts, and wildfires are observed globally.
Sea-Level Rise:
Melting glaciers and ice caps contribute to rising sea levels, threatening coastal communities and habitats.
Ecosystem Disruptions:
Shifts in habitats and changes in animal migration patterns affect biodiversity and ecosystems.
Impacts on Agriculture:
Climate change affects crop yields, water availability, and livestock, impacting food security.
