Title: Pliocene World: Earth's Climate 3 Million Years Ago and How it Relates to our Future
By Marci Robinson, USGS Research Geologist 

• Three million years ago, during the late Pliocene, CO2 levels were similar to today, but global temperatures and sea level were much higher
• Find out how we use microfossils to reconstruct temperature, salinity and more across the globe from this geological interval just before ice ages began. 
• Using our reconstruction of the Pliocene world, we better understand the climate dynamics of a warmer world, and global climate models better simulate our future climate.
