 Ozone hole shrinks to record low  



Antarctica is particularly vulnerable to ozone-depleting substances, because high winds cause a vortex of cold air to circulate over the continent.

Bad air day: Obama’s smog mistakeThe administration drank the conservative Kool-Aid and agreed that tightening ozone emission rules would have cost billions and hurt the economy. But clean air is popular politically, and the EPA’s own studies show that a tighter standard could have created $17 billion in economic benefits.
