Non-marine paleoclimatic evidence

Non-marine paleoclimatic evidence. Speleothems. Speleothems. Commonly known as stalagmites and stalactites. Like trees, speleothems form growth rings that develop over hundreds or thousands of years. Growth rate depends on amount and rate of precipitation and on cave temperature and humidity.
