90° N

How does Carbon Dioxide (CO2) influence the Earth's temperature?

CO2 absorbs outgoing infrared radiation from the Earth.

How do CO2 levels vary during the year?

CO2 levels are lower during the Northern Hemisphere's summer. CO2 levels are lower during the Northern Hemisphere's summer.

Which of the following situations would lead to the highest nighttime temperatures?

Clear conditions during the day and cloudy conditions at night

Which is the correct procedure to determine the daily mean temperature?

Determine the average of the maximum and minimum temperatures for the day.

Which of the following does the video say would most likely result from an increase in carbon dioxide levels, independent of any change in temperature?

Higher carbon dioxide levels can be good for photosynthesis.

Where would you expect to find the highest temperatures in July?

Land in the Northern Hemisphere

Where would you expect to find the highest temperatures in January?

Land in the Southern Hemisphere

Where would you expect to find the lowest temperatures in July?

Land in the Southern Hemisphere

Which of the following statements correctly explain how radiation and cloud cover interact?

More incoming radiation reaches the surface of the Earth on clear days than does on cloudy days. More outgoing radiation is reflected back to Earth on cloudy nights than is reflected on clear nights.

According to the video, which of the following locations is NOT expected to experience double-digit increases in surface air temperatures (in degrees Fahrenheit) by the year 2100?

New Zealand

What do scientists predict will happen to global temperatures during the next century?

Scientists predict temperatures will increase.

Based on what you know about how the angle of incidence of the Sun's rays affects temperatures on Earth, determine which of the following statements are correct.

The Southern Hemisphere receives more direct sunlight than the Northern Hemisphere during January. The Northern Hemisphere receives more direct sunlight than the Southern Hemisphere during July.

Calgary, Alberta, Canada, and London, England, are both situated at approximately 51°N latitude. The winter climate in Calgary is much harsher than that experienced in London. Which is the most significant reason the two cities have such different climates?

The marine location and influence of the warm North Atlantic Drift softens the winter climate in London so it is not as harsh as that experienced at Calgary.

Which of the following factors influence surface temperatures?

The presence of land The presence of ocean currents The angle of incidence of the Sun

Which response does not help explain why cities can often become urban heat islands when compared with surrounding rural areas?

Water tends to cool more slowly than land.

According to the video, in which of the following areas are human populations the most vulnerable to climate change?

countries near the equator

Which is determined by calculating the difference between the daily maximum and the daily minimum temperature?

daily temperature range

Which of the following is the LEAST likely result of global climate change?

decreased human population

High and low temp

highest temp high temp on clear days high temp on cloudy days low

What do we call a line on a weather map that connects points of equal temperature?

isotherm

According to the Coupled Climate Model, which of the following locations is forecasted to have the largest increases in average surface air temperatures?

landmasses

On a spring break vacation you decide to visit the Grand Canyon near Flagstaff, Arizona. Then you head south to visit some friends in Phoenix, Arizona. While on the drive you notice that the temperature is increasing along the route. How do you explain this?

the change in elevation

Siberia, the largest region in Russia, experiences an annual temperature range of 140°F (-70°F to 70°F), the greatest on Earth. What causes this extreme range of annual temperature?

variations in amounts of solar radiation

You live in Phoenix, AZ, where the August daily mean temperature is 93°F. You have a friend in London, England, who is coming to visit in August. She wants to know what temperatures to expect. What is the daily mean temperature in Celsius degrees?

~34°C By using the formula °C = (°F - 32)/1.8 you determine that the daily mean temperature in Phoenix while your friend is visiting should be ~34°C.

This coming summer you will be taking a week-long holiday on Prince Edward Island in Canada. You check the weather forecast for Charlottetown, PEI, and find that the daily mean temperature for the time you will be there is 27°C. What is the temperature in degrees Fahrenheit?

~81°F By using the formula °F = (1.8 × °C) + 32 you determine that the daily mean temperature on PEI while you are there should be ~81°F.
