Pliocene oceanic seaways and global climate
Tectonically induced changes in oceanic seaways had profound effects on global and regional climate during the Late Neogene. The constriction of the Central American Seaway reached a critical threshold during the early Pliocene ~4.8-4 million years (Ma) ago. Model simulations indicate the strengthening of the Atlantic Meridional Overturning Circulation (AMOC) with a signature warming response i...
متن کاملIntroduction. Pliocene climate, processes and problems.
Climate predictions produced by numerical climate models, often referred to as general circulation models (GCMs), suggest that by the end of the twenty-first century global mean annual surface air temperatures will increase by 1.1-6.4 degrees C. Trace gas records from ice cores indicate that atmospheric concentrations of CO2 are already higher than at any time during the last 650000 years. In t...
متن کاملClimate stability during the Pliocene warm period
[1] We present a high-resolution climate record from a sediment core spanning an 80-kyr interval of time during the mid-Pliocene epoch, when warmer conditions and lower global ice volume prevailed worldwide. Oxygen and carbon isotope analyses were made on benthic and planktonic foraminifera from ODP Site 981 in the North Atlantic. The amplitude and approximate recurrence interval of suborbital ...
متن کاملWorkshop on Bridging Satellite Climate Data Gaps
Detecting the small signals of climate change for the most essential climate variables requires that satellite sensors make highly accurate and consistent measurements. Data gaps in the time series (such as gaps resulting from launch delay or failure) and inconsistencies in radiometric scales between satellites undermine the credibility of fundamental climate data records, and can lead to erron...
متن کاملWorkshop on Tropical Cyclones and Climate
In final form 31 October 2006 ©2007 American Meteorological Society ropical cyclones (TCs) are among the most destructive of natural disasters. The statistics of TC occurrence and intensity are influenced by variations in the large-scale climate, but many aspects of this influence are poorly understood. Even less is known about the influence of tropical cyclones on the large-scale climate. Thes...
