A changing climate---more soybeans, fewer pine trees, lower lake levels.


ANN ARBOR---Researchers from the Great Lakes Regional Assessment Team at
the University of Michigan have released a summary report for the Great
Lakes region---"Preparing for a Changing Climate: The Potential
Consequences of Climate Variability and Change."

The report is based on information from state-of-the-art climate models
and follows closely the release of the first U.S. National Assessment
report. The Great Lakes report is a regional component of the National
Assessment process that was mandated by Congress in the Global Change
Research Act of 1990 and organized by the U.S. Global Change Research
Program (USGCRP).

The team estimates that by the year 2090 Great Lakes water levels will
be 1 to 3 feet lower; algae production, the primary food source for fish
in the Great Lakes, will likely be 10 percent-20 percent less; pine
trees may be all but eliminated from the region; dangerously high ozone
days may occur twice as frequently; and soybean yields may nearly
double.

The report focuses on results for the years 2030 and 2090. These two
times occur approximately 30 years before and after the time when
atmospheric carbon dioxide is expected to have doubled from its current
value.

The team's findings and recommendations are the work of more than 40
faculty, research associates, graduate and undergraduate students, and
external collaborators from the region and used recent output from
General Circulation Models (GCMs) that accounted for aerosols and for
steady increases in atmospheric carbon dioxide.
