- "Astronomers say a mile-wide asteroid described as "the most dangerous one we've found so far" may be on course for a near-miss -- or even a collision -- with Earth in the year 2028. The Central Bureau for Astronomical Telegrams -- which tracks asteroids -- conducted further observations that determined 1997 XF11 should pass just under 30,000 miles from Earth on October 26, 2028."
- Antarctic Rocks Yield Clues About Global Change (Science Daily 3/12)
- "In the Journal of Geology, (1997, vol. 105, p. 285-294), a UMaine team has published new evidence consistent with the view that the East Antarctic ice sheet remained stable during that period [the last 3-4 million years] and did not melt as other researchers have suggested."

- Tsunami Hunters Probe Lake Bottoms For Clues (Science Daily 3/6)
- " Exactly how big the tsunamis will be and how far inland they will reach depends on the intensity of the earthquake. Still, the best way to predict what might happen is to look back and see what's already happened. That's why a group of scientists, including SFU geographer Ian Hutchinson and plant paleontologist Rolf Mathewes, have spent the last three years probing the gooey depths of several tiny lakes on the west coast of Vancouver Island. Preliminary results of their study suggest that tsunamis on Canada's exposed west coast may be smaller than previously thought."
