"After NASA scientists claimed last August to have found evidence of past life in carbonate intrusions in the rock, skeptics argued that the chemical composition of the carbonate could only have formed at temperatures of 650 degrees Celsius or above--too high for life. But in tomorrow's Science, two papers fuel the argument with new evidence that the rock formed at comfortably low temperatures."
- Scientists Clash Over Global Warming--or Cooling? (Science Now 3/12/97)
- "The world should be warming, if climate models predicting the effects of rising levels of greenhouse gases are to be believed. But satellite data seemed to throw cold water on these predictions, suggesting that the atmosphere has in fact become slightly cooler over the last 2 decades. Now two scientists, in a report in tomorrow's issue of Nature, challenge the satellite measurements, suggesting that they actually reveal a slight warming trend."
- Global Warming Under Way (Washington Post/AP 3/11/97)
- "Satellite temperature measurements bolster the conclusion that global warming is already under way, two Colorado scientists say. The readings support last year's conclusion by an international scientific panel that 'the balance of evidence suggests that there is a discernible human influence on climate.'"
- China mine blast kills 86 (CNN/AP 3/11/97)
- "Pent-up gas exploded in a privately run coal mine in central Henan province, killing 86 people and injuring 12. The explosion was caused by an accumulation of gases inside the mine over the long Chinese New Year holiday."
- Meteorologists now can predict El Nino up to a year in advance (Nando Times 3/11/97)
- "For the first time in the history of their science, meteorologists now can predict a major climatic effect - namely, El Nino - up to a year in advance. This unprecedented ability already is paying off for Australia, Brazil and Peru. Devastating droughts or floods in those countries are linked directly to the state of the tropical eastern Pacific."
- Gigantic star discovered with diameter 370 times that of the sun (Nando Times 3/11/97)

- Global warming a recipe for disease(MSNBC 3/7/97)
- "If you thought rising oceans, heavier rains and worsening droughts were the only things to fear from global warming, try new epidemics of malaria and cholera. According to researchers at a Bethesda, Md., conference on climate and health this week, even a slight warming of global temperatures will likely be accompanied by tens of millions of additional cases of hot-weather illnesses in regions previously unaffected by them. "

"
- No fix in sight for global warming (Nando Times 3/3/97)
- "Many scientists who analyze climate change say that even the most ambitious program with any chance of adoption won't be enough to stop the atmospheric buildup of carbon dioxide, which is believed to be causing temperatures to rise."
