Overcoming Gene
Therapy’s Long Shadow
By Tanya Lewis
oN THe C ove r
As Earth warms, additional water evaporates
into the air. Warmer air, in turn, can hold more
of that vapor. A juicier atmosphere provides
extra energy and moisture for destructive
rainstorms and helps tropical storms like
Hurricane Ida intensify faster, leaving precious
little time to warn people in the crosshairs.
