Running Head : CLIMATE CHANGE IS NOTHING NEW

Climate Change is Nothing New The world is now trying to resolve the problem of global warming , a condition wherein the earth 's average near-surface temperature increases dramatically . This not only affects the human population , but also species that were adapted to live on a specific range of temperature Experts argue that the problem of global warming is due to the increased production of greenhouse gasses from human technologies and activities Global climate change , however , is nothing new , as earth has faced a series of

climate changes over the course of its history

Global surface temperature increased by as much as 0 .92 ?C for the past century . Experts concluded that the increase was likely due to the increase of greenhouse gas concentrations enhancing the greenhouse effect , while the increase of solar radiation and volcanic activities also play a small role in warming the earth 's surface . These reasons that has caused the current climate change , among others , were also the cause of past climate changes that the earth experienced . Using together evidences that hint past climates , scientists were able to determine that the earth has undergone through at least 10 ice ages in the last million years (Reibeek , 2006 , and had , therefore , undergone climate changes between and during these times

Clues embedded in the earth suggest that the earth has undergone several different climate changes in the past . Sediments in the sea reveal the amount of ice that has existed during a...
