1. * CO2 ‘Drove end to last Ice Age'
By: Diane Torres

2. About the article

The last ice age was ended by a rise in
temperature driven by an increase in atmospheric
carbon dioxide.They found very broad range of
data, including shells of ancient tiny ocean animals.
The team behind this study says this may has
something to do with global warming. "At the end of
the last ice age, CO2 rose from about 180 parts per
million (ppm) in the atmosphere to about 260; and
today we're at 392.

3. What was learned from the
article.
 This may have to do with the change in the Earth's orbit around the
Sun because it increases the amount of light reaching northern
latitudes and triggers the collapse of the hemisphere's great ice sheets
 According to the studies because of this ,fresh water that enters the
North Atlantic to upset ocean circulation is produced.
 The heat on the equator usually distributes northwards then backs
up, now it’s raising the temperature in the South
 This causes more changes to world and ocean circulation, which
causes the Southern Oceans to release CO2 from its waters
 When CO2 rises the temperature rises and there is a big change in
the climate.
