12. The United Nations, under the auspices of the Intergovernmental Panel on Climate Change, has attempted to assess the scientific understanding of how greenhouse-gas emissions will affect the climate, and thus people. The UN reports show that if we continue on our present path, burning fossil fuels at a faster and faster rate:
A) Climate will change, primarily getting warmer, and these changes will hurt everyone, equally.B) Climate will change, with cooling at high latitudes that primarily will hurt wealthy people living in C) Climate will change, primarily getting warmer, and those changes will primarily hurt the poor D) Climate will change, primarily getting warmer, and those changes will primarily hurt poor people E) Climate will change, primarily getting colder, and those changes will especially hurt those people Feedback: Blizzards play havoc with airline travel, which hurts the economy in the mid- and high-latitude wealthier countries. If you have winter (so that warming reduces blizzards), air conditioners (so you can keep the economy humming when the weather is otherwise too hot), and bulldozers (so you can build sea walls or haul things out of the way as the ocean rises), a little warming might even help your economy, although too much warming will be bad. If you are missing any of winter, air conditioning, or bulldozers, all warming is likely to be bad. Most of the world’s people are missing all three, and will be hurt by warming, but the warming is being caused primarily by people who have all three.those cold places.people in warm places who are the main causes of the climate changes through deforestation and other actions.in warm places, but the climate changes are primarily being caused by wealthier people in colder places.living in northwestern Europe.Points Earned: 0.0/1.0 Correct Answer(s):D13.
The picture above shows the stem of devil’s club, a plant of the northwestern coast of North America. The native people use devil's club for medicinal purposes. We now know that:poisonous to many things that would eat the plants; those chemicals are always harmful to humans (poison ivy, for example).poisonous to many things that would eat the plants; those chemicals are always beneficial to humans, and are the basis for all of our medicines.poisonous to many things that would eat the plants; those chemicals are sometimes harmful to humans (poison ivy, for example) but sometimes beneficial to humans, and have given us many of our medicines.
