Climate Change Facts

What Is Climate Change?

Climate change refers to long-term changes in Earth's temperatures and weather patterns. While climate has naturally changed throughout history, scientists have found that today's rapid warming is mainly caused by human activities such as burning fossil fuels, deforestation, and industrial pollution. These activities release greenhouse gases like carbon dioxide (CO₂), which trap heat in the atmosphere and warm the planet (NASA, 2025).

Fast Facts

🌍 The Earth is warming.
Global temperatures have increased significantly over the last century, with the fastest warming occurring in recent decades.

🌡️ Greenhouse gases are the main cause.
Carbon dioxide, methane, and other greenhouse gases trap heat in the atmosphere, creating the "greenhouse effect."

🧊 Glaciers and ice sheets are melting.
Warmer temperatures are causing glaciers and polar ice to shrink, contributing to rising sea levels.

🌊 Sea levels are rising.
As ice melts and ocean water expands from warming, coastal communities face increased flooding and erosion.

🌪️ Extreme weather is becoming more common.
Climate change is linked to stronger hurricanes, longer droughts, heavier rainfall, wildfires, and more frequent heat waves.

🌳 Forests help fight climate change.
Trees absorb carbon dioxide from the atmosphere. Protecting forests and planting more trees helps reduce greenhouse gases.

🐾 Wildlife is affected too.
Many animals are losing their habitats because of rising temperatures, changing weather patterns, and habitat destruction.

What Can You Do?

Everyone can help protect the environment by making small changes every day.

  • Recycle and reduce waste.

  • Use reusable bottles and shopping bags.

  • Turn off lights and electronics when not in use.

  • Walk, bike, or carpool whenever possible.

  • Plant trees and protect local green spaces.

  • Support renewable energy and environmentally friendly businesses.

  • Share accurate information about climate change with others.

Why It Matters

Climate change affects our health, food supply, water resources, wildlife, and future generations. Taking action today can reduce pollution, protect ecosystems, and create a cleaner, healthier planet for everyone. Every small action adds up, and together we can make a meaningful difference.

Did You Know?

  • Carbon dioxide levels are now higher than they have been in hundreds of thousands of years.

  • The last decade has been the warmest on record.

  • Renewable energy sources like solar and wind continue to grow and help reduce greenhouse gas emissions.

  • Scientists around the world agree that human activities are the primary cause of modern climate change.
