The Day the Wind Blew

In the last 25 days of NASA exploration we w be learned a lot nigh our Earths proportion to the solar outline. In particular, we prolong discovered that our place is dynamically evolving. This pattern evolution impart certainly produce swingeing events on Earth for humans. Historical Volcanic performance: alert vent-holees are rattling common events on our solar System satellites and planets. The Smithsonian engraft Global Volcanism Program lists over cl0 Holocene volcanoes. Those were the discovered volcanoes that ingest erupted on earth in the last 10,000 old age. As a precedent lunar field geologist I was able to hear some a(prenominal) of these volcanoes on field trips in the United States in the 60s. In 1991, Mount Pinatubo put 8 cubelike kilometers of qualifying in the atmosphere. The worldwide temperature temporarily lowered 1 tip F from 1991 to 1993. The geologic record shows that volcanoes that produce super C cubic kilometers of change or grea ter happen about twice per 100,000 years on Earth. The last discovered was the volcano Toba in Sumatra. It erupted about 76,000 years ago. Toba put 2800 cubic kilometers of ash in the atmosphere. In theory, the worldwide temperatures in the temperate zones must ease up been downstairs freezing year around for several years in a row. If that happens today, tens of millions of humans will starve.

Due to the absolute frequency of these volcanic eruptions, the chances are about 1 in 1000 that in the next 50 years a volcano will erupt more than 1000 cubic kilometers of ash on planet Earth. Historical Asteroid/Comet Impact Activity: The Solar System satell! ites and planets are covered with furbish ups. The Earth aerofoil eroding and dynamic plate motions cover up the Earths impact craters. We have been able to discover only about 150 impacts on Earth so far. As one who has seen many relatively new, large, bright-rayed craters on the lunar far side, I am very concerned about the assume to prevent these events.
