Current Climate change effects in the Antarctic Better known as the Penguin Activity Better known as the Penguin Activity

What we know for sure about climate change: Mechanism of the greenhouse effect Mechanism of the greenhouse effect CO 2 at the beginning of the Industrial revolution: 280ppm CO 2 at the beginning of the Industrial revolution: 280ppm CO 2 today: 398ppm CO 2 today: 398ppm CO 2 increases.5%/year CO 2 increases.5%/year Since 1860 global mean temp has increased.6-.7 o C ( o F) Since 1860 global mean temp has increased.6-.7 o C ( o F)

IPCC: Intergovernmental Panel on Climate Change UN group of scientists representing almost every country UN group of scientists representing almost every country Jan 2007 – issued report on climate change. Jan 2007 – issued report on climate change. Absolute agreement on anthropogenic cause of current climate change. Absolute agreement on anthropogenic cause of current climate change. “Warming of the climate system is unequivocal” “Warming of the climate system is unequivocal” “There is very high confidence that the net effect of human activities since 1750 has been one of warming.” “There is very high confidence that the net effect of human activities since 1750 has been one of warming.”

What effects of these changes are we already seeing?

CO 2 levels currently Mauna Loa Observatory - Hawaii Mauna Loa Observatory - Hawaii CO2 at beginning of Industrial revolution: 280 ppm CO2 at beginning of Industrial revolution: 280 ppm Current CO 2 levels: 398ppm Current CO 2 levels: 398ppm Current CO 2 levels: 398ppm Current CO 2 levels: 398ppm (watch the movie – when is CO2 highest? Where??? Why???) (watch the movie – when is CO2 highest? Where??? Why???)

The poles are experiencing more intense change Winter temps rising faster than summer temps Winter temps rising faster than summer temps Average temperature change is double the change at lower latitudes. Average temperature change is double the change at lower latitudes. 3-4 o C in 50 years (5 - 7 o F) 3-4 o C in 50 years (5 - 7 o F)

The importance of ice cover: The albedo effect: The albedo effect: Incoming radiant energy hits a white surface and is reflected – it bounces without being converted to infrared energy Incoming radiant energy hits a white surface and is reflected – it bounces without being converted to infrared energy

Today: determine relationships

AND relationships between some abiotic factors: Air temperature Air temperature Sea ice extent Sea ice extent Winter snow Winter snow

Make a prediction: Predict the relationship between one of the biotic factors and one of the abiotic factors in this activity Biotic: krill, chinstrap penguins, adelie penguins Biotic: krill, chinstrap penguins, adelie penguins Abiotic: air temperature, sea ice extent, winter snow Abiotic: air temperature, sea ice extent, winter snow

Expert groups: Complete Part I examine data set examine data set Summarize key information provided about your biotic or abiotic factor Summarize key information provided about your biotic or abiotic factor You have 15 minutes You have 15 minutes

Home Group: Go get: big paper, glue, 6 different cards, colored pencils Go get: big paper, glue, 6 different cards, colored pencils Make a concept map which shows relationships between abiotic and biotic factors. Make a concept map which shows relationships between abiotic and biotic factors. Include cards, arrows, explanations Include cards, arrows, explanations When you are sure about the relationships, glue them down When you are sure about the relationships, glue them down

So how did that prediction work out for you? Describe something you learned about the effects of climate change from doing this activity. Describe something you learned about the effects of climate change from doing this activity.

Soooo..... What does the penguin activity show you? Feedback loops play a role in climate change (identify them) Feedback loops play a role in climate change (identify them) Complexity of a system makes prediction difficult (give an example) Complexity of a system makes prediction difficult (give an example) Biodiversity loss – populations may not be able to adapt quickly enough Biodiversity loss – populations may not be able to adapt quickly enough A “little” change (.7 o C/1 o F) is a big deal A “little” change (.7 o C/1 o F) is a big deal
