What would result from the jet stream shifting?



  1. 0 Votes

    The Jet Stream, the massive currents of air that flow miles above the Earth and largely dictate weather patterns all around the world, are shifting by small amounts due to global warming, according to recent studies. Global warming is effecting the expansion of the atmosphere around the equator, which is pushing these rivers of air farther north and south toward the poles. While the small shifts (approx. 1.25 miles a year) occurring thus far are not seriously changing weather patterns, greater shifts could change precipitation and temperature patterns too rapidly for plants and animals to adjust, threatening many species worldwide. Changing weather patterns would also have repercussions for farming, storm systems, and may even result in more hurricanes in the future. It remains to be seen if these shifts will escalate to dangerous degrees in the future.
