In 1988, James Hansen projected future warming trends. He used 3 different scenarios, identified as A, B, and C. Each represente
d different levels of greenhouse gas emissions. All three indicated a strong cause and effect relationship between observed
temperatures and human emissions of greenhouse gases into the atmosphere. Greenhouse gas emissions are at the center of
almost all climate change concerns. What are the likely effects of increasing Greenhouse gas emissions on the ecosystem? Select
ALL that apply.
A)
rising sea-levels and ocean acidification
B)
changes in precipitation resulting in flooding and droughts
more extreme, erratic, unpredictable weather, including intense hurricanes
D)
decreases in respiratory illnesses due to the warming temperatures and
shorter winters
E)
increases in agriculture production due to increased CO2 availability for
photosynthesis
