1. Notes from Friday, Feb 23rd

2. Message in Nissan Commerical
Bear is thankful of the man driving an electric car that doesn’t burn fossil fuels. WHY?
Burning fossil fuels increases CO2 concentrations in atmospheric
Increase in CO2 , causes increase in temperature
Increase in temperature causes the ice melt (where the polar bear lives)

3. What is the main human cause of global warming?
Burning fossil fuels
which releases greenhouse gases (mainly, carbon dioxide) into the atmosphere…
These gases absorb long-wave radiation (heat energy) being radiated back from earth.
The CO2 molecules then re-emit the long-wave radiation back to earth….
Resulting in the atmosphere getting warmer.

4. Climate Change Effects
Increases in temperature
Sea level rise
Ice mass loss (ice is going to melt)
Shifts in flower/plant blooming
