...people listened to Arrhenius then, as few people listened in the next century to others who issued the same warning, a little louder each time. TIME came late to global warming by the standards of the Swedish chemist, but early by most measures. We published our first cover story on the topic in October 1987. "It is too soon to tell whether unusual global warming has indeed begun," wrote Michael D. Lemonick. But if the climate did begin to change, we could expect "dramatically altered weather patterns, major shifts of deserts and fertile regions, intensification of tropical storms...
Still, as far back as the late 1890s, Swedish Chemist Svante Arrhenius had begun to fret that the massive burning of coal during the Industrial Revolution, which pumped unprecedented amounts of CO2 into the atmosphere, might be too much of a good thing. Arrhenius made the startling prediction that a doubling of atmospheric CO2 would eventually lead to a 9 degrees F warming of the globe. Conversely, he suggested, glacial periods might be caused by diminished levels of the gas. His contemporaries scoffed. Arrhenius, however, was exactly right. In his time, the CO2 concentration was about 280 to 290 parts...
...From the "panspermia" theory of Swedish Chemist Svante Arrhenius, who suggested in 1908 that living cells floated haphazardly through the universe, bringing life to desolate planets...
Asteroid walks would be high adventure. Weighing less than an ounce in full space gear, an astronaut might jump half a mile off the surface before drifting gently back down. But Alfvèn and Arrhenius suggest limiting such activity to asteroids at least a mile across...
...undertake such an adventure in the near future, there is little time to lose. In 1975, Alfvèn and Arrhenius note, an asteroid that seems almost ideal for exploration will come within 14 million miles of earth. It is 15 miles long and five miles wide, and will be traveling only 5,600 m.p.h. relative to the earth. That asteroid is Buck Rogers' favorite: Eros...
