Trapping of heat by gases in the atmosphere, keeping Earth warm enough for life.

Gases that trap heat, contributing to the greenhouse effect. Examples: CO2, methane, nitrous oxides, CFCs, and ozone.

A greenhouse gas, released naturally and through human activities (burning fossil fuels).

A greenhouse gas, occurring naturally and having significant human sources (agriculture, landfills).

A gas in the atmosphere, beneficial in the stratosphere (protects from UV radiation), but harmful in the troposphere (smog).

Microscopic particles in the air, from natural sources (dust) and human activities (pollution).

The study of past climates using indirect evidence (proxy data).

Indirect evidence used to reconstruct past climates, like tree rings or ice cores.

Using tree rings to study past climates.

Indirect evidence of past climates.

Cylindrical samples of ice used to study past atmospheric composition.

Coral skeletons show growth patterns reflecting climate conditions.

Examining pollen in sediment layers to understand past vegetation and climate.

Written accounts (journals etc.) used to study past climate.

Variability in energy from the sun over time.

Changes in Earth's orbit affecting climate over long periods.

Changes in Earth's orbit around the sun, tilt, and wobble of its axis of rotation cause glacial and interglacial periods over 100,000-year cycles.

Ash from volcanic eruptions can reflect sunlight, leading to a temporary cooling effect on Earth's climate.

The Intergovernmental Panel on Climate Change (IPCC) is a global group of scientists who assess the scientific, technical, and socio-economic information relevant to understanding climate change.

There is strong scientific evidence that human activities are changing the global climate.

Global surface temperatures are projected to increase by between 1.4°C and 5.8°C during this century.

A continuous circulation of ocean water that transports heat and influences global climate.

Increased ocean temperatures can fuel stronger and more intense hurricanes.

Melting ice sheets, glaciers, and thermal expansion of ocean water all contribute to rising sea levels.

The Arctic region experiences warming at a faster rate than the rest of the planet.

Melting sea ice disrupts ecosystems, impacting polar bear survival and human communities.

A navigable sea route through the Arctic Ocean, now increasingly accessible due to melting sea ice.

Computer simulations that incorporate human emissions and natural factors to project future climate scenarios.

Decomposing organic matter in the ocean releases carbon dioxide, contributing to the greenhouse effect.

The increase in acidity of ocean water due to the absorption of carbon dioxide from the atmosphere.

Ocean acidification makes it difficult for marine organisms like corals, shellfish, and plankton to build their calcium carbonate shells and skeletons.

The decline in the productivity of land, often caused by loss of vegetation and soil erosion.

Climate change can increase the likelihood and severity of droughts, especially in areas with warmer and drier conditions.

Climate change can contribute to an increase in wildfires, especially in areas with warmer temperatures and drier conditions.

An international agreement to phase out the production of chemicals (CFCs) that were depleting the ozone layer.

An international agreement aiming to reduce greenhouse gas emissions by nations to combat climate change.

Canada's decision to withdraw from the Kyoto Protocol due to concerns about achieving emission reduction targets.

A global conference focused on alternative methods for reducing emissions, including clean development methods, joint implementation, and emission trading.

Strategies employed by developing nations to improve their carbon balance, often through environmentally friendly practices like renewable energy and sustainable agriculture.

A collaborative effort where developing countries receive financial and technical assistance from wealthy nations to reduce emissions, resulting in shared emission credits.

A market-based system where countries exceeding their emission reduction targets can sell their surplus credits to countries struggling to meet their targets.

An international accord aimed at limiting global warming well below 2°C, with efforts to pursue 1.5°C, through shared commitments from participating countries.

The process of capturing and storing carbon dioxide (CO2) before it enters the atmosphere, effectively removing it from circulation.

A future where reliance on fossil fuels remains high, resulting in a significant temperature increase of about 4.5°C and a potential sea level rise of 1.4 meters.

A more optimistic future where clean and resource-efficient technologies are widely adopted, leading to a smaller temperature increase of about 2°C and a potential sea level rise of 0.5 meters.
