Our
proposal for IGCP Project 555 “Rapid Environmental/Climate
Change in the Cretaceous Greenhouse World:
Ocean-Land Interactions” was one of several
new IGCP projects approved by the UNESCO-IUGS
IGCP Scientific Board during its 35th
session in early 2007. Our four-year project
will run from 2007 to 2010.
Recently the
Earth’s climate has oscillated between
glacial and inter-glacial episodes with
ice sheets expanding on the northern hemisphere
continents, and permanent ice restricted
to Antarctica and Greenland...
Our
goal is to investigate the causes, processes,
and consequences of rapid environmental
changes in the Cretaceous greenhouse world.
In contrast to the oscillating glacial-interglacial
climates of the past few million years,
the Cretaceous was a time of long term
climate stability with warm equable climates
resulting from a higher atmospheric greenhouse
gas content...
