What are essential ecosystem services provided by the Earth?
- Purifying water
- Producing oxygen
- Recycling materials
- Processing carbon dioxide
Global warming threatens these services, endangering the environment and human well-being.

What are direct impacts of increased temperature on health?
- Heatstroke, particularly in the elderly
- More intense tropical storms and cyclones
Rising ocean heat intensifies storms.
What is a significant concern for coastal regions due to climate change?
Sea level rise
Heat causes water to expand, posing a major sustainability threat for islands with populations and tourism.
What are evident shifts in climate patterns?
- Unseasonal rainfall
- Flooding
- Property damage
- Loss of lives
Some Caribbean countries now experience heavy rainfall during the dry season.
What economic impacts are being felt due to climate change?
- Increased insurance prices
- Rising food prices
These economic consequences are already affecting people today.
True or False: Climate change exacerbates existing issues like pollution and poverty.
True
This makes solutions to these issues more challenging.
What is the primary cause of the warming trend observed in the Earth’s climate?
Human activities
Particularly the use of fossil fuels.
Define ‘warming trend’.
A long-term increase in the average temperature of the Earth’s climate system
This trend is largely driven by human activities.
What process do greenhouse gases contribute to?
The greenhouse effect
This process traps heat in the atmosphere, leading to a warming effect on the planet.
What are fossil fuels?
Energy resources formed from the remains of ancient plants and animals
Examples include coal, oil, and natural gas.
What is the concentration unit for gases in the atmosphere?
Parts per million (ppm)
This unit measures the concentration of gases like carbon dioxide.
Fill in the blank: Human activities have significantly increased _____ levels.
CO₂
This increase leads to a substantial and long-lasting warming effect.
What are two key human activities contributing to climate change?
- Driving cars
- Using electricity from coal power plants
Both activities release significant amounts of CO₂.
What is the greenhouse effect?
The process where certain gases in Earth’s atmosphere trap heat
This effect is crucial for maintaining Earth’s temperature.
What is the impact of increased CO₂ on climate?
It acts as a greenhouse gas that absorbs and re-emits heat radiation
This leads to a warmer climate.
What has been the global temperature rise since pre-industrial times?
Approximately 1°C
This rise is primarily due to human-induced factors.
What are the consequences of climate change on agriculture?
- Reduced crop yields
- Increased food insecurity
These effects pose a threat to global food supply.
What is the goal of the Paris Agreement?
To limit global warming to well below 2°C
Countries submit national plans to cut emissions.
Define ‘mitigation’ in the context of climate change.
Actions to reduce greenhouse gas emissions
This includes measures like switching to renewable energy.
What does NDC stand for?
Nationally Determined Contribution
It refers to a country’s self-defined climate action plan under the Paris Agreement.
What is a Small Island Developing State (SIDS)?
An island nation with development challenges and high climate sensitivity
Examples include Trinidad and Tobago.
What is the role of the UNFCCC Secretariat?
Support negotiations and implementation of climate agreements
It facilitates transparency and accountability.
What is the ACE initiative?
Action for Climate Empowerment
It promotes training, public engagement, and curricula integration on climate issues.
