Climate Change Natural Impacts

Name?

What has been causing the Earth's atmospheric temperature to increase since 1850?

• Decrease in greenhouse gases
• Emission of greenhouse gases
• Depletion of ozone layer
• Increase in solar radiation

What has been the main consequence of the excess heat trapped by greenhouse gases?

• Decrease in atmospheric temperatures
• Decrease in ocean temperatures
• Increase in atmospheric temperatures
• Increase in ocean temperatures

Which regions are expected to be warmer than others in the world's oceans?

• Waters near Greenland
• Waters near the poles
• Waters near the equator
• Eastern coast of South America, western coast of central Africa and Northeast Asia

What changes does climate change bring to terrestrial ecosystems?

• Rise in global atmospheric temperature
• Excessive rainfall in some areas leading to floods
• Dry regions becoming even drier, leading to droughts
• Increases in global ocean circulation
• Decrease in greenhouse gas emissions

How does climate change affect the global ocean circulation and surface temperatures?

• Causes all of the world’s oceans to experience an increase in surface temperatures
• Increases the speed of global ocean circulation
• Causes all of the world’s oceans to experience a decrease in surface temperatures
• Stops the global ocean circulation
• Slows down the global ocean circulation

A. Based on the text, how is climate change affecting the global ocean circulation?

• Climate change is slowing down the global ocean circulation
• Climate change is speeding up the global ocean circulation
• Climate change is making the global ocean circulation more erratic
• Climate change is not affecting the global ocean circulation

B. Which sentence from the text best supports your answer to Part A?

• Do you know that the water in our oceans is constantly moving around the world?
• Most of the excess heat trapped by these gases has been absorbed by the world’s oceans, causing their temperatures to increase
• Since the oceans are so huge, the temperature change seems small
• However, climate change is expected to slow down this global circulation of water

A. What impacts does climate change have on terrestrial ecosystems according to the text?

• Climate change is causing a decrease in rainfall leading to droughts in every area
• Climate change is causing an increase in rainfall in all areas leading to floods everywhere
• Climate change is causing excessive rainfall in some areas leading to floods and is making dry areas even drier, leading to droughts
• Climate change is making wet areas drier and dry areas wetter

B. Which sentence from the text best supports your answer to Part A?

• The lack of moisture can further reduce the occurrence of rain
• Do you notice that from 1910 onwards, the average global surface sea temperature has been rising steadily?
• Climate change is causing an increase in excessive rainfall in some areas...Climate change will result in dry areas becoming even drier, and may increase the occurrences of droughts in these areas
• This is because water at the surface gains heat due to rising atmospheric temperatures
