Ocean Carbon Pumps: Analysis of Relative Strengths and Efficiencies in Ocean‐Driven Atmospheric CO2 Changes
T. Volk, M. Hoffert
It is concluded that a broad range of intensive research and development is urgently needed to produce technological options that can allow both climate stabilization and economic development.
The United Nations Framework Convention on Climate Change calls for “stabilization of greenhouse-gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic…
M. Hoffert, C. Covey
To assess the future impact of anthropogenic greenhouse gases on global climate, we need a reliable estimate of the sensitivity of the Earth's climate to changes in radiative forcing. Climate…
Unless climate sensitivity is low and acceptable amounts of climate change are high, climate stabilization will require a massive transition to CO2 emission–free energy technologies.
The role of deep sea heat storage in the secular response to climatic forcing
M. Hoffert, A. Callegari, C. Hsieh
The influence of the world oceans on climatic response is considered here with emphasis on the heat transferred to waters beneath the well-mixed surface layer and to polar bottom water forming zones.…
Effects of Subgrid-Scale Mixing Parameterizations on Simulated Distributions of Natural 14C, Temperature, and Salinity in a Three-Dimensional Ocean General Circulation Model
P. Duffy, K. Caldeira, J. Selvaggi, M. Hoffert
Abstract The effects of parameterizations of subgrid-scale mixing on simulated distributions of natural 14C, temperature, and salinity in a three-dimensional ocean general circulation model are…
S. Davis, N. Lewis, +29 authors K. Caldeira
The special challenges associated with an energy system that does not add any CO2 to the atmosphere (a net-zero emissions energy system) are reviewed and prominent technological opportunities and barriers for eliminating and/or managing emissions related to the difficult-to-decarbonize services are discussed.
M. Hoffert, Yeong-Cherng Wey, A. Callegari, W. Broecker
The possibility of controlling atmospheric carbon dioxide accumulation and attendant climatic effects from fossil-fuel burning by diverting a fraction of the combustion product and injecting it into…
