Much of the U.S. electricity is generated in thermal generating stations that burn fossil fuels such as coal and natural gas. The use of solar-powered generating stations is expected to increase over the next decade and replace older fossil-fuel generating stations. What impact might this change have on greenhouse gas emissions?
Which statement best describes the cause of the Earth's warming in recent decades? Which one is it?
1. Volcanic eruptions have increased in frequency, causing more greenhouse gases to be emitted.
2. The sun has become brighter, causing the planet to absorb more heat.
3. Greenhouse gases like carbon dioxide have increased in concentration. This has prevented some of the radiation that normally leaves the Earth's atmosphere from leaving, causing the temperature l to increase.
4. The species of plant that normally absorb sunlight have undergone genetic mutations, causing them to emit heat rather than absorb it.
Which predicted consequence of global warming has not yet occurred?
(a) Melting ice caps
(b) Rising sea levels
(c) Melting permafrost
(d) Shutting down the thermohaline circulation of the ocean
(e) Altered breeding times and flowering times of animals and plants
