7 SCIENCE that "a well-defined layer of radioactive cesium is now present in polar glaciers, providing a new reference for estimating snow accumulation rates and dating ice core samples.' Because the Chernobyl cloud extended only into the troposphere (where, within weeks, particles either fall out or are washed out with precipitation), it left a much clearer signal in the ice than did past nuclear weapons tests, which spewed radioisotopes into the stratosphere where residence times exceed a year.
The heat is causing the polar glaciers to melt and it is feared that this will cause ocean levels to rise, inundating low-lying islands around the world.
This greenhouse effect continues for tens of thousands of years, transferring more and more moisture to the growing polar glaciers and creating an ice age.
