Climate Change 1
What historical event in the 1800s caused average global temperatures to increase drastically?
The Industrial Revolution
True or False: Climate change refers to SHORT-TERM fluctuations in weather patterns.
False. Climate change refers to LONG-TERM shifts in global or regional climate patterns.
What is the term for the process by which solar radiation is trapped by the Earth's atmosphere, leading to an increase in global temperatures?
The greenhouse effect.
What process naturally removes carbon dioxide from the atmosphere and releases carbon dioxide
photosynthesis
Fossil fuels are a renewable resource.
True or Falsle
False
What are the 3 main green house gasses
methane, water vapor, carbon dioxide
How do green house gases cause the Earth's temperature to rise?
They absorb the sun's radiation and trap heat
How does deforestation contribute to climate change?
Deforestation removes trees, which are natural carbon sinks, leading to an increase in atmospheric CO2 levels.
How would Earth's temperature be without green house gases?
Earth's temperatures would be cold, oceans would freeze
All of the radiation from the sun is absorbed by the Earth.
True or False
False
Why is the increase of Greenhouse gasses a big issue?
It causes climate change and increase in the global temerature
Which two green house gases contribute the most to global warming?
Carbon dioxide and Methane
Which countries are presently emitting the most CO2? ( list 2)
US/ China
What are 3 examples of fossil fuels?
Oil, coal and gas
The average weather for a region over a long period of time is. _______________.
Climate
What is the greenhouse effect?
Certain gasses in the atmosphere trap heat and warm the Earth
Burning these contributes to global warming.
Burning fossil fuels
As global warming continues, the intensity of what type of storm that hits coastlines is predicted to increase?
Hurricanes
How can global warming cause sea levels to rise?
Melting glaciers and ice caps
During what time period did the human population increase from 2 billion to 6 billion?
List four things that are evidence of global climate change?
1. rising global temperatures
2. melting ice caps and sea level rise
3. More severe storms
4. Ocean acidification
What do we call the act in cutting down trees and other shrubbery.
deforestation
What government agency protects people and the environment from significant health risks, sponsors and conducts research, and develops and enforces environmental regulations. ?
The Environmental Protection Agency (EPA)
How can we as humans minimize the amout of green house gases we emit into the atmosphere?
drive less
turn off lights
burn fewer fossil fuels
What is the main source of methane emissions that contributes to climate change?
Agriculture, particularly livestock farming (cattle, sheep, etc.), as well as landfills.
