An unnatural weather change Effects on Adelie Penguins Lizzy Plotkin Thomas Daigneau Amanda McCracken

Slide 2

Presentation Outline “Based on different investigative proof, we envision that on the Antarctic Peninsula, fast environmental change is prompting populace decrease of the Adelie Penguins.” Background Information Meet the Penguins Antarctica Global Warming The Consequences… In the Future Two Adelie penguins

Slide 3

Meet the Adelie Penguins Pygoscelis adeliae Smallest Antarctic Penguin species Ice Dependent Rapid Population Decline A Group of Adelie Penguins

Slide 4

Area of Study Antarctic Peninsula Map Antarctic Peninsula Home of the Adelie Mostly on the Peninsula 177 provinces Average Temperature: 0 to - 10 °C Adelie Penguin states in Antarctica

Slide 5

Global Warming Basics Starting at the Industrial Revolution Increase in Greenhouse Gasses Many Possible Causes Global warming patterns from 1860 to 2001

Slide 6

Effects on Antarctica Winter Temperature has risen 9 °F in most recent 50 years Unpredictable yet sensational Ice Melting Glacier Calving Species Loss Antarctic ice sheet calving

Slide 7

The Consequences Adelie Population as a Result of Sea Ice Extent and Air Temperature Adelie Population and Sea Ice Extent (1978-2005)

Slide 8

The Food Chain A base's graph up natural pecking order comprising of ice green growth, krill and the Adelie Penguins. So what’s the issue?

Slide 9

Effects of Ice Melting Decline in ice green growth reasons soften up natural pecking order Blocks in regular scrounge ways Destruction of homes Glacier calving Heavier snows Slush versus ice and rock

Slide 10

STELLA Model STELLA model demonstrating the impacts of liquefying ice's on the Ice populaces Algae, Krill, and Adelie penguin species.

Slide 11

STELLA RESULTS A chart contrasting the Ice's populaces Algae, Krill and Adelie penguins with the temperature change in Antarctica. Adelie penguin populace with the temperature change in the Antarctic landmass.

Slide 12

Continuation of ice misfortune Loss of settling destinations More liquefying Sun’s beam on dry ice versus wet ice T b=E T s Further separate of the natural pecking order Species adjustment to new corners Homogenization Less differing speciation Future Predictions Larsen B ice rack, fifth March 2002 (after 16 days) Larsen B ice rack, seventeenth Feb 2002

Slide 13

What You Can Do Limit utilization of fossil fills Use less vitality Recycle Spread the word Sign up to offer assistance! Greenpeace International You’ll make the penguins much more satisfied!
