1. Using NASA’s website on climate change answer the following questions:
https://climate.nasa.gov/
A) how much has temperature risen since 1880?;
B) how much has global sea level risen over the past 100 years (in either millimeters, inches, or cms)?;
C) what is the current rate of global sea level rise per year in millimeters?
D) what is the current level of atmospheric CO2 and how does this level rank over the past 650,000 years? What is the cause of the observed changes in climate over the last century?
2. Discuss at least three techniques/data sets scientists use to learn about past climates?
3. The International Panel on Climate Change (IPCC) has identified projections of future climate changes. State one projection that is either “virtually certain” or “very likely/high confidence” for each of these 5 categories: Temperature; Ocean; Polar Region; Weather Patterns; Biosphere (pgs 243-244 SEE ATTACHMENT)Discuss at least three techniques/data sets scientists use to learn about past climates?
4. As climate change continues, in which climate zones are disappearing climates most likely to occur? Why those locations in particular? Name and describe 4 examples of threats to Earth’s biodiversity.
