C02 and climate: a missing feedback?
Nature, 1989THE potential of changes in cloud properties to modulate climate perturbations is well known1,2. Changes in cloud amount and cloud height3, cloud radiative properties4–6 and cloud condensation nuclei7 (CCN) have all been recognized as possible sources of climate feedbacks. Here we report results of simulations that indicate that the changes of state of

Action du laser C02 sur le spectre d'absorption infrarouge du C02
Bulletin de la Classe des sciences, 1973Le travail met en évidence l'effet d'un laser C02 sur le spectre d'absorption de ce même gaz dans la région de 15 fi. On étudie plus spécialement le comportement des raies d'absorption sous l'effet d'un rayonnement laser régulièrement interrompu.

, 2000 The market mechanisms built into the Kyoto Protocol have the potential of significantly reducing costs of limiting greenhouse gases. But if trading proceeds on a bilateral project-by-project basis rather than on a frictionless market, the total cost saving potential of trading is unclear.

EPA HAS DENIED A 1999 PETItion from environmental groups asking the agency to regulate carbon dioxide from motor vehicles under the Clean Air Act. The agency provides two primary reasons for its Aug. 28 decision: The Clean Air Act does not give EPA authority to regulate CO 2 for climate-change purposes, and setting up emissions standards for motor ...

C02 Recovery by way of pH Swing [PDF]
A demand for the reduction in GHG emissions from the worldwide community has seen the energy industry pressured to address its contribution to this dilemma. In recent decades there has been a push toward research into technologies that would provide energy at an affordable price while keeping with GHG emission standards, which are rising as fast ...

Geochimica et Cosmochimica Acta, 1995
Abstract In many geologic environments, dominantly aqueous solutions contain low concentrations of CO2. At ambient temperature, the typical phase assemblage in fluid inclusions which trap these solutions, consists of a CO2-rich vapor (where PrmCO2 ≈ Pinternal and an aqueous phase containing dissolved salts and CO2.

On Modelling the Effects of C02 on Climate
1986The sensitivity of the Meteorological Office’s 5-layer atmospheric general circulation model to enhanced atmospheric C02 concentrations with both a uniform and a latitudinally varying increase in sea surface temperatures is assessed. The changes in atmospheric temperatures depend on the sea surface temperature increases imposed, but the geographical ...

Degreasing of protein-hydrolysate by SC-C02
The Journal of Supercritical Fluids, 1991Abstract The degreasing of a protein-hydrolysate, produced from a pigs-brain raw material, was investigated. A production process based on the removal of fats by dichloromethane should be replaced by a process using an alternative solvent. Therefore, a supercritical-fluid-extraction using C0 2 as a solvent was performed.

C02 Laser Design and Laboratory Projects
IEEE Transactions on Education, 1972The design of an inexpensive CO2 laser and some associated laboratory projects are described. The laser is easily constructed by undergraduate students. The experiments are designed to familiarize students with some characteristics and applications of CO2 lasers.
