Emmanuel Quiroz is from Benicia, CA. He is class of , majoring in Biological Engineering Course He is doing a UROP at the Wittrup Lab, finding a bispecific protein that tags and eliminates tumorous colon cancer cells. Antarctic ice core analysis has provided scientists with a history of climatic and atmospheric changes over the past quarter of a million years. A similar rise and fall of temperature and CO 2 has been observed in all of the ice core records. Three main CO 2 and temperature relations are suggested with supporting evidence, but uncertainties and outside factors need to be taken into account.

Ice cores and climate change - British Antarctic Survey
Scientists working in the Allen Hills region of Antarctica have drilled the oldest ice core ever. Dating back an estimated 2. Up until recently, scientists faced a problem finding extremely old ice core samples. Heat from the Earth's core tends to melt the super deep layers of ice over time, and the oldest ice core scientists thought they were able to harvest was around , years old.
Climate Data Information
How far into the past can ice-core records go? Scientists have now identified regions in Antarctica they say could store information about Earth's climate and greenhouse gases extending as far back as 1. By studying the past climate, scientists can understand better how temperature responds to changes in greenhouse-gas concentrations in the atmosphere.
Ice cores are one of the most effective, though not the only, methods of recreating long term records of temperature and atmospheric gases. Particularly in the polar region, but also at high elevations elsewhere, snow falls on an annual cycle and remains permanently. Over time, a few decades, the layers of snow compact under their own weight and become ice.
