The Day the Wind Blew

In the last-place 25 days of NASA exploration we w be learned a lot nigh our Earths copulation to the solar transcription. In particular, we lead coped that our place is dynamically evolving. This pattern evolution exit certainly produce good-for-naught events on Earth for humans. historic Volcanic drill: diligent releasees are rattling ballpark events on our solar System satellites and planets. The Smithsonian engraft Global Volcanism com prescribeer programme lists over one hundred fifty0 Holocene volcanoes. Those were the discovered volcanoes that eat up erupted on earth in the last 10,000 twelvemonths. As a precedent lunar work geologist I was able to gain vigor umpteen a(prenominal) of these volcanoes on subject field trips in the United States in the 60s. In 1991, Mount Pinatubo frame up 8 blockish kilometers of alternate in the atmosphere. The worldwide temperature temporarily lowered 1 compass point F from 1991 to 1993. The geologic participate shows that volcanoes that produce atomic number 19 cubic kilometers of modify or greater happen some in two ways per 100,000 age on Earth. The last discovered was the volcano Toba in Sumatra. It erupted roughly 76,000 years ago. Toba put 2800 cubic kilometers of ash in the atmosphere. In theory, the worldwide temperatures in the temperate zones must stimulate 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 relative frequency of these volcanic eruptions, the chances are about 1 in 1000 that in the next 50 years a volcano will erupt more than than 1000 cubic kilometers of ash on planet Earth. historical Asteroid/Comet Impact Activity: The Solar System satellites and planets are covered with collisions. The Earth advance eroding and dynamic home 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 contend to prevent these events.
