What is the main idea of “City Under Siege”?

In Paragraph H, why does Gulledge make an analogy with heating water on a stove? H      As the oceans warm, they’re giving off more water vapor. “Everybody knows that if you turn up the fire on your stove, you evaporate the water in a pot more rapidly,” says Jay Gulledge, senior scientist at the Center for Climate and Energy Solutions (C2ES), a think tank3 in Arlington, Virginia. During the past 25 years satellites have measured a 4 percent average rise in water vapor in the air. The more water vapor, the greater the potential for intense rainfalls. The amount of rain falling in intense downpours—the heaviest one percent of rain events—has increased by nearly 20 percent during the past century in the U.S. “You’re getting more rain from a given storm now than you would have 30 or 40 years ago,” says Gerald Meehl, a senior scientist at the National Center for Atmospheric Research in Boulder, Colorado. Global warming, he says, has changed the odds for extreme weather.

In Paragraph L, why does Gulledge compare weather disasters to heart attacks? L      Weather disasters are like heart attacks, says Jay Gulledge. “When your doctor advises you about how to avoid a heart attack, he doesn’t say, ‘Well, you need to exercise, but it’s OK to keep smoking,’” he says. The smart approach to extreme weather is to attack all the risk factors, by designing crops that can survive drought, buildings that can resist floods and high winds, policies that discourage people from building in dangerous places—and of course, by cutting greenhouse gas emissions.

What is the purpose of the first two paragraphs (Paragraphs A–B)?

The “standby mode” on electronic devices

How does the section Weather Gone Wild support the author’s argument?

Match the word with its meaning.

Despite unpredictable weather, the world’s largest PV solar industry can be found here.

We can infer that another way to refer to “climate change” is “global warming.”

The author’s family switched to wind energy to further reduce their carbon footprint.
