True or False: All plants, animals and people are affected by changes in the climate
Define climate change
How many degrees has the temperature risen in the last 100 years?
Define global warming.
Explain why a SMALL change in temperature can make a big difference. Name two changes that could occur.
What does a paleoclimatologist study?
Explain what a proxie is.
Why do scientists want to find out information about how the Earth's climate changed during the past?
Name two proxies of climate change
How do scientists know the amounts of greenhouse gasses in the atmosphere at certain times during the past?
True or False: All cars are fueled by petroleum
How can a car be more fuel efficient?

Explain why deforestation is believed to be causing Earth's climate to change.
very cold
CFC's
water vapor
Carbon dioxide
100 Years
True
change in weather patterns over a long period of time
1 degree
an average increase in Earth's surface temperature
sea levels will rise, hurricanes will become stronger and more intense, glaciers will melt, more droughts and heatwaves
past climate changes
They are examples of evidence showing changes in the climate and greenhouse gasses
It will give them a prediction of future events
ice core samples, tree rings, coral samples,sedimentary rock samples, sediment layers
they study air bubbles trapped in ice samples
false
use the AC less, buy smaller compact cars that get good gas milage
Large SUV or Trucks with low gas milage
burning coal
The same amount of land was used, but the machines used now add to burning fossil fuels and increasing temperatures
occured naturally in the past
train
More people means more cities, more homes and more heating and cooling needs, more fossil fuels will be burnt, more transportation and vehicles will be needed
driving cars. electricity, heating and cooling homes and buildings, building cities, farming, water heating, cooking, waching clothes
trees absord carbon dioxide. If the trees are cut down, then there is nothing to absord the carbon and the gasses get released into the atmosphere
