EVERYDAY SCIENCE

Detailed explanation-1: -By measuring the ratios of different water isotopes in polar ice cores, we can determine how temperature in Antarctica and Greenland has changed in the past.

Detailed explanation-2: -Ice cores can tell scientists about temperature, precipitation, atmospheric composition, volcanic activity, and even wind patternsIce cores can tell scientists about temperature, precipitation, atmospheric composition, volcanic activity, and even wind patterns.

Detailed explanation-3: -Clues about the past climate are buried in sediments at the bottom of the oceans and lakes, locked away in coral reefs, frozen in glaciers and ice caps, and preserved in the rings of treesTo extend those records, paleoclimatologists look for clues in Earth’s natural environmental records.

Detailed explanation-4: -Geological materials like dust and minerals provide clues about wind patterns, water currents and volcanic events. Biological materials like microscopic shelled organisms, algae, pollen grains and spores provide clues about temperature, nutrient levels, ice cover, oxygen levels and salinity.
