Current models of the global carbon cycle lack natural mechanisms to explain known large,
transient shifts in past records of the stable carbon-isotope ratio (δ13C) of carbon reservoirs …

The processes controlling the carbon flux and carbon storage of the atmosphere, ocean and
terrestrial biosphere are temperature sensitive,,, and are likely to provide a positive feedback …

The response of the terrestrial carbon cycle to climate change is among the largest
uncertainties affecting future climate change projections,. The feedback between the …

Abstract The Early Eocene Climate Optimum (EECO, which occurred about 51 to 53 million
years ago), was the warmest interval of the past 65 million years, with mean annual surface …

The continued increase in the atmospheric concentration of carbon dioxide due to
anthropogenic emissions is predicted to lead to significant changes in climate. About half of …

The lack of an adequate ancient analogue for future climates means that we ultimately must
use and trust climate models, evaluated against modern observation and our best geologic …

Global climate and the concentration of atmospheric carbon dioxide (CO2) are correlated
over recent glacial cycles,. The combination of processes responsible for a rise in …

Abstract The Middle Eocene Climatic Optimum (MECO) was an approximately 500,000-year-
long episode of widespread ocean–atmosphere warming about 40 million years ago …

Terrestrial ecosystems and the climate system are closely coupled, particularly by cycling of
carbon between vegetation, soils and the atmosphere. It has been suggested, that changes …
