refers to any significant change in the measures of climate lasting for an extended period of time and includes major changes in temperature, precipitation, or wind patterns, among other effects, that occur over several decades or longer.
What is climate change?
Tells you what type of clothes to have in your closet.

What does the earth's tilt cause?
A. The seasons
B. Day and Night
C. Tsunamis
D. Earthquakes
A. The seasons
Certain gases in the atmosphere – water vapor, carbon dioxide, methane and nitrous oxide – help maintain the Earth’s temperatures and climate. These are called: __________ .
A ozone gases
B solar gases
C greenhouse gases
D stomach gases
C greenhouse gases
Something that might happen because of global warming is: __________.
A melting polar ice caps
B more reflected sunlight off the ice pack
C lower sea levels
D a sale on bathing suits
A melting polar ice caps
We can reduce the risks we will face from climate change.
True
False
True
By making choices that reduce greenhouse gas pollution, and preparing for the changes that are already underway, we can reduce risks from climate change. Our decisions today will shape the world our children and grandchildren will live in.
Where do air masses acquire their temperature and humidity characteristics?
What effect does the tilt of the earth have?
A. It changes the angle that the sun strikes the earth in different land areas
B. It causes the earth to be farther away from the sun at different times of the year
C. When the earth is tilted away from the sun we have night
D. When the earth is tilted away from the sun we have day
A. It changes the angle that the sun strikes the earth in different land areas
Global warming is caused only by natural factors.
True
False
False
Changes in the climate are partially due to natural forces and partially due to human activities. Scientists now believe that most of the planet's warming in the last few decades has been due to our emissions of GH gases.
Which of the following industries could be negatively affected by global warming?
D. All of the above
D. All of the above
Insurance companies can expect to pay out more in disaster claims. The fishing industry will suffer from depleted fish stocks. Some wine regions will no longer be able to sustain grape crops.
Some changes to the climate are unavoidable.
True
False
True
Carbon dioxide can stay in the atmosphere for nearly a century, so Earth will continue to warm in the coming decades. The warmer it gets, the greater the risk for more severe changes to the climate and Earth's system. Although it's difficult to predict the exact impacts of climate change, what's clear is that the climate we are accustomed to is no longer a reliable guide for what to expect in the future.
The area where the dry/cold air mass meets the humid/hot air mass is called:
Which of the following best describes the tilt of the earth when it is summer in the southern hemisphere?
A. The northern hemisphere is tilted toward the sun
B. The northern hemisphere is tilted away from the sun
C. The norther hemisphere is tilted neither toward or away from the sun
D. Why are you talking about the northern hemisphere when you asked about the southern hemisphere?
B. The northern hemisphere is tilted away from the sun
The solar energy that warms the Earth includes visible light, infrared and _____ coming from the sun.
A gamma rays
B ultraviolet radiation
C microwaves
D sunspots
B ultraviolet radiation
A rise in global temperature is expected to increase instances of certain human disease.
True
False
True
For example: Rising temps allow mosquitoes to survive at higher altitudes, potentially bringing them to regions that lack population immunity. In addition, the transmission period for vector-borne diseases is increased with expanded warm seasons.
How much have sea levels risen in the past 100 years?
A. 7 inches
B. 2 inches
C. 5 inches
D. 16 inches
A. 7 inches
On average, global sea level has risen about seven inches in the last 100 years. By 2100, sea level is expected to increase by another 1.5 to 3 feet, resulting in stronger and more frequent storm surges.
Wind is created when cold air rushes into an emptier space because previously:
Which of the following best describes the tilt of the earth during the spring and fall equinoxes?
A. The earth is tilted away from the sun (Northern hemisphere)
B. The earth is tilted neither toward or away from the sun (tilt is side to side)
C. The earth is tilted toward the sun (Northern hemisphere)
D. The earth is not tilted during spring and fall
B. The earth is tilted neither toward or away from the sun (tilt is side to side)
The solar radiation that bounces off the Earth back toward the atmosphere is mostly _____ (with a longer wavelength).
A gamma radiation
B x-ray radiation
C nuclear radiation
D infrared radiation
D infrared radiation
Global warming is accelerated by the reduction of global snow and ice cover.
True
False
True
Ice-covered surfaces reflect more solar energy than ice-free surfaces and therefore have a global cooling effect. As ice-covered surfaces are reduced, global warming will accelerate because more heat will be absorbed.
How much have global average temperatures increased in the last century?
A. 2.1 degrees Fahrenheit
B. 0.6 degrees Fahrenheit
C. 4.3 degrees Fahrenheit
D. 1.5 degrees Fahrenheit
D. 1.5 degrees Fahrenheit
Global average temperatures have increased more than 1.5 degrees Fahrenheit over the last 100 years. Scientists project that Earth's average temperature will rise between two and 12 degrees Fahrenheit by 2100. It's estimated that a change of just two degrees in average global temperature could result in sea level rise, lower crop yields, increased rainfall and flooding, more wildfires and other negative environmental impacts. The historic climate agreement involving 196 nations at the 2015 United Nations Climate Change Conference set a goal to limit global warming to less than 3.6 degrees Fahrenheit.
