The Environment Flashcards
What signs of global warming are being seen around the world?
Arctic ice and permafrost are disappearing
Antarctic ice sheets are melting into the oceans
Tropics are experiencing more frequent and destructive storms and floods
European glaciers are disappearing
Why has global warming become more of a problem to society in recent years?
Due to the increased demand for energy, more fossil fuels are being burnt thus releasing phenomenal volumes of carbon dioxide into the atmosphere
What are the problems involved with global warming?
Flooding Drought Can lead to improved growth of crops in some areas but is generally associated with food shortages Rising sea levels Unpredictable weather
What substitutes do we have to fossil fuel plants?
Wind turbines
Tidal power
Solar plants
Nuclear plants
What is CCS?
Carbon capture and storage; the process of capturing carbon dioxide from power stations and storing it away safely
Where can carbon dioxide be stored?
In underground porous rock
In old oil fields and gas fields
In underground pipes
Can be reacted to form metal carbonates
How does carbon dioxide help with the oil extraction industry?
The last 30% of oil from an oil field is difficult to extract but with the aid of waste carbon dioxide being pumped in helps to extract more oil
What is the problem with converting carbon dioxide into carbonates?
The reaction is very slow
Would have to be very energy intensive to be worthwhile
