Question 29

What is Global Warming?

Answer 29

Global Warming is where infrared radiation becomes stuck in the Earth's atmosphere and heats up the earth. This is because CO² and other gases from fossil fuels rrap the infrared radiation, stopping it from leaving Earth's atmosphere.

Question 30

What is Carbon Capture Storage (CCS)?

Answer 30

Carbon Capture Storage (CCS) is the process of capturing waste CO². The CO² is deposited somewhere, where it wont be released into the atmosphere. The aim is to prevent the release of large quantities of CO² into the armosphere.
