Professor Park Je - Geun, Associate Director of the Center for Correlated Electron Systems (CCES), within the Institute for Basic Science (IBS), and colleagues have observed, quantified and created a new theoretical model of the coupling of two forms of collective atomic excitation, known as magnons and phonons in crystals of the antiferromagnet manganite (Y, Lu) MnO3, a mineral made of manganese oxide and rare - earth elements called yttrium (Y) and lutetium (Lu).

Within the integrated Earth system science paradigm, our major research thrusts include the physics and chemistry of aerosols, clouds and precipitation; integrating our understanding of climate, energy, and other human and natural systems through the development and application of models that span a wide range of spatial scales; and determining the impacts of and informing responses to climate and other global and regional environmental changes.

ECCO model - data syntheses are being used to quantify the ocean's role in the global carbon cycle, to understand the recent evolution of the polar oceans, to monitor time - evolving heat, water, and chemical exchanges within and between different components of the Earth system, and for many other science applications.

(1) In this case even if they were correct and the models failed to predict or match reality (which, acc to this post has not been adequately established, bec we're still in overlapping data and model confidence intervals), it could just as well mean that AGW stands and the modelers have failed to include some less well understood or unquantifiable earth system variable into the models, or there are other unknowns within our weather / climate / earth systems, or some noise or choas or catastrophe (whose equation has not been found yet) thing.

The challenges are significant, but the record of progress suggests that within the next decade the scientific community will develop fully coupled dynamical (prognostic) models of the full Earth system (e.g., the coupled physical climate, biogeochemical, human sub-systems) that can be employed on multi-decadal time - scales and at spatial scales relevant to strategic impact assessment.

So it seems to me that the simple way of communicating a complex problem has led to several fallacies becoming fixed in the discussions of the real problem; (1) the Earth is a black body, (2) with no materials either surrounding the systems or in the systems, (3) in radiative energy transport equilibrium, (4) response is chaotic solely based on extremely rough appeal to temporal - based chaotic response, (5) but at the same time exhibits trends, (6) but at the same time averages of chaotic response are not chaotic, (7) the mathematical model is a boundary value problem yet it is solved in the time domain, (8) absolutely all that matters is the incoming radiative energy at the TOA and the outgoing radiative energy at the Earth's surface, (9) all the physical phenomena and processes that are occurring between the TOA and the surface along with all the materials within the subsystems can be ignored, (10) including all other activities of human kind save for our contributions of CO2 to the atmosphere, (11) neglecting to mention that if these were true there would be no problem yet we continue to expend time and money working on the problem.
