 "Build-Up
of Carbon Dioxide Slows Down," N. Parks, Earth,
20-22, May 1994.
Data from Hawaii's Mauna Loa Observatory indicate that CO2
levels began to stabilize in mid-1991 although emissions
continued to increase. Speculates about the sink for
"missing" carbon.
Item #d94jun177
"Insects
That Carry a Global Warning," S. Young, New Scientist,
32-35, Apr. 30, 1994.
Insects used as sensitive indicators of global warming show
that signs of warming are already evident on the Arctic island of
Spitsbergen. Whether this reflects long-term climate change or a
broad natural cycle is not clear.
Item #d94jun178
"Drilling
for a Past Climate," H. Beltrami, D. Chapman, ibid.,
36-40, Apr. 23, 1994.

warming can be explained by natural fluctuations in the Earth's
temperature.
