Climate and atmospheric history of the past 420,000 years from the Vostok ice core,
- Antarctica. Nature
, 1999
"... Antarctica has allowed the extension of the ice record of atmospheric composition and climate to the past four glacial-interglacial cycles. The succession of changes through each climate cycle and termination was similar, and atmospheric and climate properties oscillated between stable bounds. Inte ..."

The ice record The data are shown in Figs 1, 2 and 3 (see Supplementary Information for the numerical data). They include the deuterium content
Response of a Coupled Ocean–Atmosphere Model to Increasing Atmospheric Carbon Dioxide: Sensitivity to the Rate of Increase
- JOURNAL OF CLIMATE
, 1999
"... The influence of differing rates of increase of the atmospheric CO 2 concentration on the climatic response is investigated using a coupled ocean–atmosphere model. Five transient integrations are performed each using a different constant exponential rate of CO 2 increase ranging from 4 % yr �1 to 0. ..."

, 1997
"... Abstract. We examine the sensitivity of a climate model to a wide range of radiative forcings, including changes of solar irradiance, atmospheric CO2, 03, CFCs, clouds, aerosols, surface •bedo, and a "ghost " forcing introduced at arbitrary heights, latitudes, longitudes, seasons, and time ..."

Target atmospheric CO2: where should humanity aim?
- Open Atmospheric Science Journal,
, 2008
"... Paleoclimate data show that climate sensitivity is ~3°C for doubled CO 2 , including only fast feedback processes. Equilibrium sensitivity, including slower surface albedo feedbacks, is ~6°C for doubled CO 2 for the range of climate states between glacial conditions and icefree Antarctica. Decreasi ..."

Measurement of the apparent dissociation constants of carbonic acid in seawater at atmospheric pressure
, 1973
"... The apparent dissociation constants of carbonic acid in seawater were determined as functions of temperature (2-35°C) and salinity ( 19-43%) at atmospheric pressure by measurement of K’1 and the product K’, K’,. At 35sa salinity and 25°C the measured values were pE1 = 6.600 and pK’2 = 9.115; at 35 % ..."

Biogeochemical controls and feedbacks on ocean primary production
- Science
, 1998
