November,1997
Global Warming argument goes back centuries (Reuters 11/29)
"Climate negotiators from around the world come to their meeting in Kyoto next week on greenhouse gas emissions armed with centuries' worth of science to argue their cases on what to do about global warming."
Snapshot of Climate Change Science (Washington Post/AP 11/29)
A brief summary of what is known and what is still uncertain about global climate change.
Greenhouse gases could chill Europe (CNN/AP 11/27)
Columbia scientist warns that global warming could trigger collapse of ocean currents (Science Daily 12/1)
"Currents flowing like rivers from pole to pole and from ocean to ocean help keep the Earth's weather in a steady state, but the buildup of greenhouse gases in the atmosphere is threatening this circulation and could dump Europe into a deep freeze, a researcher says."
Big splash: Scientists describe asteroid's ancient ocean plunge (CNN/AP 11/26)
"An asteroid that tumbled through space for eons blasted into the sea off Antarctica more than 2 million years ago with the force of "a cosmic bomb," a multinational team of scientists said in a research paper published Wednesday [in Nature]."
World Views on Global Warming (Washington Post/AP 11/22)
"The threat of global warming has brought more than 140 governments together in intensive negotiations to try to limit the emissions of carbon dioxide and other 'greenhouse gases' that trap heat in the atmosphere. But history, geography, economics and politics are driving them apart."
List of Greenhouse Gas Emissions (Washington Post/AP 11/22)
"Top 10 emitters of carbon dioxide in 1992, in millions of metric tons and in tons per capita: United States -- 4,881 (19 tons per capita); China -- 2,668 (2 per capita); Russia -- 2,103 (14 per capita); Japan -- 1,093 (9 per capita); Germany -- 878 (11 per capita); India -- 769 (1 per capita); Ukraine -- 611 (12 per capita); Britain -- 566 (10 per capita); Canada -- 410 (15 per capita); Italy -- 408 (7 per capita)."
Study Finds Striking Environmental Change In Arctic (Science Daily 11/21)
"The Arctic experienced its highest temperatures in 400 years between the mid-19th and mid-20th centuries. Contrary to previous assumptions, the evidence indicates that the Arctic is characterized by significant climatic change even without the influence of environmental effects caused by humans."
Ice ages on a knife-edge (Nature Science Updates 11/20)
"During this cold snap [the Little Ice Age], separate and semi-permanent snow-fields in the Arctic, in Labrador and Baffin Island, very nearly became confluent. Had they done so, the snow would have become permanent, turning into a glacier, flipping the EarthÕs climate into another Ice Age."
A chinese window on early mammal evolution (Nature Science Updates 11/20)
Fossil May Provide Evolution Clue (Washington Post/AP)
"An unusually clear picture of the early stages of mammal evolution are apparent in a fossil skeleton of a 145-million-year-old rat-sized creature from China."
New Theory Provides Explanation For Flowing, Liquid Water On Ancient Mars (Science Daily 11/17)
"How could Mars--at Pathfinder's landing site a chilly minus 100 F--once have been warm enough to have liquid water on its surface? The answer, says a University of Chicago climatologist and his French colleague, is reflective carbon-dioxide ice clouds that retain thermal radiation near the planet's surface."
Earth Cools In Persistent, 1,500-Year Rhythm, Say Columbia Scientists, Working From Sea Cores (Science Daily 11/14)
"Earth's climate cools significantly and abruptly every 1,500 years or so in a persistent, regular rhythm, a team led by scientists at Columbia University's Lamont-Doherty Earth Observatory reports in the Nov. 14 issue of the journal Science."
Drilling Uncovers Ancient Eruptions That May Have Caused Global Warming (Science Daily 11/12)
"Drilling into the sea floor south of Haiti has uncovered conclusive ashy evidence that multiple massive volcanic eruptions occurred roughly 55 million years ago in the Caribbean Basin. Those cataclysmic events appear to have caused abrupt inversion of ocean waters, triggering one of the most dramatic climatic changes ever."
The power and fury of tsunamis (Seattle Times 11/11)
"Signs, in Clallam, Jefferson, Grays Harbor and Pacific counties, are just the beginning of a regional public-awareness campaign, local emergency-management officials say. They would like Washington's coastal residents to instantly think "run to high ground" when they feel the ground shaking."
Glitch causes 1-year delay in Mars mapping mission (CNN/Reuters)
"A mechanical problem on board the tiny robotic spacecraft orbiting Mars will force a one-year delay in its main mission to map the entire red planet, U.S. space officials said Monday. "
China begins building world's largest dam (CNN 11/8)
"Chinese President Jiang Zemin led a celebration honoring the beginning of the building of the world's largest dam as workers began sealing off a dike to divert the Yangtze River."
Solar storms could put a jolt into earthly affairs (CNN 11/6)
"Two solar storms are headed toward Earth, and when they arrive over the next few days the effects could be costly and inconvenient."
Galileo finds Arizona-sized volcanic deposit On Jupiter's moon Io (NASA News Release 11/6)
"Observations taken by NASA's Galileo spacecraft five months apart reveal a new dark spot the size of Arizona on Jupiter's moon Io, indicating that dramatic volcanic activity occurred during that time." (Galileo Image)
Mount Adams' changing face (Seattle Times 11/4)
"Late October ushered in a series of significant avalanches heard by distant seismometers. The October landslides and another series of landslides in August left scars about 3 miles long on different sides of the massive volcanic mountain."
Astronomers find 2 new moons of Uranus (CNN/AP 11/1)
Two New Moons Of Uranus Discovered (Science Daily 11/1)
"Astronomers have discovered two small moons orbiting Uranus, bringing to 17 the number of moons circling the seventh planet."
Tree-Ring Study Enables Researchers To Link Massive American Earthquake To Japanese Tsunami In January 1700 (Science Daily 11/1)
"Two University of Washington researchers believe that evidence in the dead wood [of red cedar trees] confirms that in the year 1700 a great earthquake struck the Pacific Northwest coast and set off a tsunami, a train of massive ocean waves, that flooded coastal Japan."
So Who Owns Dinosaur Bones (Washington Post/AP 11/1)
"For years, private land owners have cooperated with scientists wanting to dig up dinosaur fossils on their property. But the record $8.4 million paid recently at a public auction for a Tyrannosaurus rex fossil already has some landowners seeing dollar signs."
Dinosaurs In Motion (Discover Magazine 11/97)
"Computer scientists and paleontologists are joining forces to get the very largest of Earth's extinct giants moving again, this time the right way."
