On November 7, 2013, Typhoon Haiyan (Yolanda in the Philippines) made landfall, with imated wind speeds of ~315 km/hr - the strongest <a href="/earth/Atmosphere/hurricane/intensity.html&dev=1/earth/Atmosphere/moons/h/neptune/games_junk.html">tropical cyclone</a> to make landfall in recorded history.  As Haiyan moved across the Philippines before reaching Vietnam and China, its <a href="/earth/Atmosphere/wind.html&dev=1/earth/Atmosphere/moons/h/neptune/games_junk.html">winds</a> and <a href="/earth/Atmosphere/hurricane/surge.html&dev=1/earth/Atmosphere/moons/h/neptune/games_junk.html">storm surge</a> left devastation in its wake, leading to massive loss of life, destruction of homes, and hundreds of thousands of displaced inhabitants. <a href="http://www.cnn.com/2013/11/09/world/iyw-how-to-help-typhoon-haiyan/index.html">How to Help</a><p><small><em>Image courtesy of COMS-1, SSEC, University of Wisconsin-Madison</em></small></p>A new study has found that <a href="/earth/Atmosphere/airpollution_intro.html&dev=1/earth/Atmosphere/moons/h/neptune/games_junk.html">pollution</a> from <a href="/earth/Atmosphere/particulates.html&dev=1/earth/Atmosphere/moons/h/neptune/games_junk.html">fine particles</a> in the air - mainly the result of burning coal or <a href="/earth/interior/eruptions.html&dev=1/earth/Atmosphere/moons/h/neptune/games_junk.html">volcanic eruptions</a> - can shade <a href="/earth/Life/cnidarian.html&dev=1/earth/Atmosphere/moons/h/neptune/games_junk.html">corals</a> from sunlight and cool the surrounding water resulting in reduced growth rates.

They are similar to crepuscular rays, but are seen opposite the sun in the sky. Anti-crepuscular rays are most frequently visible near sunrise or sunset. This photo of anti-crepuscular rays was taken at sunset in Boulder, Colorado. Crepuscular rays are usually much brighter than anti-crepuscular rays.<p><small><em> Image Courtesy of Carlye Calvin</em></small></p>How did life evolve on <a href="/earth/earth.html&dev=1/earth/Atmosphere/moons/h/neptune/games_junk.html">Earth</a> during the <a href="/earth/past/Archean.html&dev=1/earth/Atmosphere/moons/h/neptune/games_junk.html">Archean</a>, when the <a href="/sun/sun.html&dev=1/earth/Atmosphere/moons/h/neptune/games_junk.html">Sun</a> was about 25% weaker than today?
