Climate change
Today we are experiencing rapid warming from human activities, primarily due to _________ that generate ___________.
burning fossil fuels, greenhouse gas emissions.
Increasing __________ from human activity act like a blanket wrapped
around the earth, trapping the sun’s heat, and raising temperatures.
greenhouse gas emissions
Examples of greenhouse gas emissions that are causing climate change include _________ and _______.
carbon dioxide and methane.
Carbon Emissions
• These come from burning fossil fuels such as gasoline for driving a car or coal for heating a building.
• Clearing land and forests can also release carbon dioxide.
• Landfills for garbage are another source.
• Energy, industry, agriculture and waste disposal are among the major emitters.
The four major emitters.
Energy, industry, agriculture and waste disposal
Switching energy systems from fossil fuels to _______ will reduce the emissions driving climate change.
renewables like solar
Fossil fuel production must decline by roughly ______ per year between 2020 and 2030.
6 per cent
How do we reduce carbon emissions
- Reduce your energy use and switch to renewable energy.
- Change what you eat.
- Change the way you travel.
- Change how much you buy and who you buy from.

Excessive carbon release
In the process of photosynthesis, trees absorb carbon and convert it into nutrients required for their development. The ______ the forest, the more carbon it can store.
younger
