.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?
carbon dioxide (CO2) is a colorless, odorless, faintly acidic-tasting, non-flammable gas. CO2 is the fourth most abundant gas in the earth's atmosphere
2) According to the CO2 charts, what was the highest level of CO2 in the 400,000 years prior to 1950?
280 parts per million
3) According to the charts, what is the level of CO2 today?
higher than 350
4) Based on the information on the page, why is this level of CO2 a problem?
climate change becasue of it so may cause global warming
5) According to the charts on Arctic Sea Ice, what has been the overall trend since 1980?
1.71
6) What trend can be observed for land ice?
decrease 287.0
7) What trend can be observed for sea level?
increase 3.24
8) What overall conclusion can you make based on the data of these three charts?
that there are mostly decreases which means there is global warming occuring
Evidence
9) What are eight areas that scientists look at for evidence of global warming?
carbon dioxide, global temperature, artic ice minimum , land ice , sea level
Causes
10) What are the five common gases that cause global warming?
chloroflurocarbons, nitrous oxide ,methane, carbon dioxide, water vapor
Effects
11) According to the effects page, what effect will climate change have on water availability?
more droughts and heat waves the glaciers will melt though and then parts of earths surfaces will be covered in water.
12) What visible changes have already occurred due to climate change?
glaciers melting and the heat change so the climates and temperatures have changed
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.
harness ocean energy wind farms greener spacecraft
