Today’s Plan Logistics Field notes on a Catastrophe Ch. 3, 4

Today’s Plan

• Logistics

• Field notes on a Catastrophe Ch. 3, 4

Additional comments about Autobiographies

• Some too long (and repetitive)– stick to range in assignment– good exercise to remove unneeded words!

• First paragraph get to main point (e.g. location)• Topic sentences of paragraphs give main point

of paragraph• Go through assignment and make your own

checklist of key points or “deliverables”

Autobiography Comments Continued

• Example of getting rid of “to be” verbs– The location I chose is Timberline Lodge because my

family went there often and I loved looking at the mountain.

– Edit 1: I chose Timberline Lodge because my family went there often and I loved looking at the mountain.

– Edit 2: My family often visited Timberline Lodge, where the stunning views of the mountain nourished my childhood dreams of climbing adventures.

• Avoid too much conditional voice– I would imagine many visitors feel the same…– I imagine many visitors feel the same…

Autobiography Comments Continued

• Some copy edits– Underline: (see comment in margin or just noting a potential

error)– Checkmark: a notable point– Question mark: something doesn’t sound right, confusion– awk: sounds awkward here– loop or cross out: deletion suggested

• Stretch yourself—some stuck to same theme used in artifact assignment

• Write for some one who hasn’t seen assignment or taken class—an educated, but general reader

• Proofreading Log

Field notes Chapters 1&2 Review

• Chapter 1(Artic Change)– Shishmaref, AK (close up, further)– NOAA Artic Ice Extent Sept. 2002-2008– Drunken Forests– Albedo (ratio of reflected to incident light)

• Chapter 2 (History of CO2-warming connection)– Historical

• John Tyndall (mid 1800s)– Absorption of infrared by CO2, methane, water vapor (but not

Oxygen and Nitrogen)• Svante Arrhenius

– First model of effect of CO2 on global temperature

– Charles Keeling Curve CO2 and global warming

Field notes Chapter 3 (Glaciers)

• Swiss Camp, Greenland– Konrad Steffen research group– Above artic circle– Speaker Pelosi Visit

• Acceleration of Greenland Ice– 13 inches a day in 1996; 20 inches a day 2001– A Positive Feedback

• “acceleration of Greenland ice sheet suggests yet another feedback mechanism: once an ice sheet begins to melt, it starts to flow faster, which means it also thins out faster, encouraging further melt” p. 54

• “Particularly alarming, Corell said, were the most recent data from Greenland, which showed the ice sheet melting much faster ‘than we thought possible even a decade ago.’” p. 63
