A

• Adaptation: Making changes to live with the effects of climate change.
• Air Pollution: Harmful gases or particles released into the air.
• Atmosphere: The layer of air around the Earth.

B

• Biodiversity: The variety of plants, animals, and other living things on Earth.

C

• Carbon Dioxide (CO₂): A gas from burning coal, oil, gas, and trees, which causes global warming.
• Carbon Footprint: The amount of carbon dioxide a person or activity adds to the atmosphere.
• Climate: The usual weather in a place over a long time.
• Climate Change: Changes in the usual weather, like more heat, rain, or storms, over many years.
• Conservation: Protecting nature, like forests and animals.

D

• Deforestation: Cutting down forests.
• Drought: A long time without rain, making the land very dry.

E

• Ecosystem: A community of plants, animals, and their environment working together.
• Emissions: Gases released into the air, like from cars or factories.
• Energy Efficiency: Using less energy to do the same work, like using LED lights.

F

• Fossil Fuels: Fuels like coal, oil, and gas made from old plants and animals.
• Flood: Too much water covering land, usually after heavy rain.
• Feedback Loop: A chain reaction where one change leads to another, making the first change bigger or smaller.

G

• Global Warming: The Earth getting hotter because of too much carbon dioxide.
• Greenhouse Effect: When gases in the atmosphere trap heat from the sun, making Earth warm.
• Greenhouse Gases: Gases like carbon dioxide and methane that trap heat in the atmosphere.
• Glaciers: Big, slow-moving rivers of ice found in cold places.

H

• Heatwave: A period of very hot weather.

I

• Industrialization: Building factories and cities, often causing more pollution.
• Ice Caps: Large areas of ice covering land or water in the Arctic and Antarctic.
• Irreversibility: Changes that cannot be undone.

L

Landfill: A place where garbage is buried in the ground.

M

• Methane (CH₄): A powerful greenhouse gas from animals, landfills, and oil production.
• Mitigation: Actions to reduce the effects of climate change, like planting trees.

N

Natural Disasters: Events like hurricanes, wildfires, or earthquakes that can harm people and nature.
Net Zero: Balancing the amount of harmful gases we put in the air with the amount nature can remove.

O

• Ozone Layer: A layer of gas in the atmosphere that protects us from harmful sunlight.

P

• Pollution: Harmful substances added to the air, water, or land.
• Precipitation: Rain, snow, or other water falling from the sky.
• Permafrost: Ground in very cold places that stays frozen all year.
• Positive Feedback Loop: When a small change keeps growing, like melting ice making the Earth warmer.

R

• Recycling: Reusing materials like plastic, paper, and metal to make new products.
• Renewable Energy: Energy that comes from natural sources like the sun, wind, or water.
• Rainforest: A forest with a lot of trees and rain, home to many animals and plants.
• Reduce, Reuse, Recycle: Three ways to make less waste and protect nature.

S

• Sea Level Rise: The ocean getting higher because of melting ice and warmer water.
• Solar Energy: Energy from the sun.

T

• Temperature: How hot or cold it is.
• Tipping Point: A moment when changes in the climate become unstoppable.

W

• Weather: The condition of the air (rain, heat, wind) over a short time.
• Wind Energy: Power made from the wind using turbines.

Z

• Zero Emissions: No greenhouse gases released into the atmosphere.
