Power Tools for Technical Communication: Headings Practice


In this lab, you compose and add headings to a technical document:
  1. Copy the text below this box, and paste it into your preferred word-processing software.

  2. Add second- and third-level headings at the appropriate points in the text and at the appropriate levels. Read carefully!

  3. You are welcome to use other fonts or other typographical effects, but bold on these headings works just fine.

  4. Put your name, Headings Practice: Print, and the date on this document, and either print it out or show it on screen to your instructor, or send it be e-mail attachment to your instructor.


Terrance Joyce, who chairs the Woods Hole Physical Oceanography Department, believes that the cooldown could begin in 10 years. According to Joyce, "Once it does, it could take hundreds of years to reverse." In a recent letter to The New York Times, he challenged readers to "recall the coldest winters in the Northeast, like those of 1936 and 1978, and then imagine recurring winters that are even colder, and you'll have an idea of what this would be like."

A 5 to 10 degree drop in temperature could have devastating ecological and economical effects. The National Academy of Sciences (NAS), in a recent article titled "Abrupt Climate Change: Inevitable Surprises," reported that the cost from agricultural losses alone could reach $100 billion to $200 billion and that damage to ecologies could be "vast and incalculable." They predicted accelerated species extinctions, disappearing forests, low crop yields, inflated housing costs, and dwindling freshwater. The faster the climate change is, according to most predictions, the more dire the consequences will be.

Another prevailing concern is the effect a small ice age would have on the world's poor. In a modern world with closed borders, those living in drastically changing climates would not have the option to simply pick up and move south like ancient tribes did during previous cooling periods. According to the NAS report, "To the extent that abrupt climate change may cause rapid and extensive changes of fortune for those who live off the land, the inability to migrate may remove one of the major safety nets for distressed people."
