Climate Change Web-Quest
Directions- Go to: climate.nasa.gov and using the information of the website, answer the following questions. Write your answers in the space provided.
Key Indicators
1) What is carbon dioxide (CO2) and where does it usually come from?
It is a greenhouse gas that comes from fossil fuels.
2) According to the CO2 charts, what was the highest level of CO2 in the 400,000 years prior to 1950?
Above 400
3) According to the charts, what is the level of CO2 today?
401.69 ppm
4) Based on the information on the page, why is this level of CO2 a problem?
Because it has been the highest in years.
5) According to the charts on Arctic Sea Ice, what has been the overall trend since 1980?
It’s been going down since 1980.
6) What trend can be observed for land ice?
Land ice is decreasing
7) What trend can be observed for sea level?
Sea level is increasing
8) What overall conclusion can you make based on the data of these three charts?
That the melted ice in cause the sea level to increase.
Evidence
9) What are eight areas that scientists look at for evidence of global warming?
Sea level rise, Global temperature rise, Warming oceans, shrinking ice sheets, Declining Arctic sea ice, Glacial retreat, Extreme events, Ocean acidification
Causes
10) What are the five common gases that cause global warming?
Carbon dioxide, Chlorofluorocarbons, Nitrous oxide, Methane, water vapor
Effects
11) According to the effects page, what effect will climate change have on water availability?
It will decrease water availability
12) What visible changes have already occurred due to climate change?
Melting of the ice caps
Consensus
13) What percentage of scientists agree that climate change is due to human activity?
97%
Innovations
14) Describe three innovations in energy that could help the world become independent of fossil fuels.
