The session explores regional integration of records and dynamic modeling to: (1) understand better the nature of climate - human - ecosystem interactions; (2) quantify the roles of different natural and anthropogenic drivers in forcing environmental change; (3) examine the feedbacks between anthropogenic activity and the natural system and; (4) provide integrated datasets for model development and data - model comparisons.
Given the political climate and opportunities for change — the availability of stimulus funds (including Secretary of Education Arne Duncan's commitment of $ 350 million in stimulus funding to support assessment work), the movement toward common standards, and the upcoming reauthorization of No Child Left Behind — we can bypass the debate between the two flawed options of either maintaining the status quo or returning to performance - based assessment systems of the 1990s.
Global climate change appears to be an example where a dissociation between the output of the analytic and the affective system results in less concern than is advisable, with analytic consideration suggesting to most people that global warming is a serious concern, but the affective system failing to send an early warning signal (Weber, 2006).
We believe that negative synergies between deforestation, climate change, and widespread use of fire indicate a tipping point for the Amazon system to flip to non-forest ecosystems in eastern, southern and central Amazonia at 20 - 25 % deforestation.

There has been a recent emphasis in decadal - scale prediction, and also creating a marriage between climate and fields such as synoptic - dynamic meteorology... something relatively new (and a different sort of problem, than say, estimating the boundary condition change in a 2xCO2 world); as Susan Solomon mentioned in her writing, a lot of people have become much more focused on the nature of the «noise» inherent within the climate system, something which also relates to Kevin Trenberth's remarks about tracking Earth's energy budget carefully.
And through conversations with others in the growing climate justice movement, I began to see all kinds of ways that climate change could become a catalyzing force for positive change — how it could be the best argument progressives have ever had to demand the rebuilding and reviving of local economies; to reclaim our democracies from corrosive corporate influence; to block harmful new free trade deals and rewrite old ones; to invest in starving public infrastructure like mass transit and affordable housing; to take back ownership of essential services like energy and water; to remake our sick agricultural system into something much healthier; to open borders to migrants whose displacement is linked to climate impacts; to finally respect Indigenous land rights — all of which would help to end grotesque levels of inequality within our nations and between them.
Rather, the ice core record shows clearly that changes in temperature precede changes in carbon dioxide throughout the glacial - interglacial cycle (Mudelsee, 2001), and that for the last half million years the climate system has oscillated in a self - limiting way between glacials and interglacials by about 6 deg.
Natural variability might modulate the flow of energy between parts of the system, such as from ocean to atmosphere, but the «pace of climate warming», as in the general gain in energy (or loss of energy) of the entire climate system, can only be dictated by some external forcing, such as somthing that changes the amount of solar radiation reaching the surface, volcanoes, or changes in GH gas concentrations.

Adapting core principles of risk assessment to climate: To date, the approach of climate change assessments has primarily been rooted in communicating relative scientific certainty and uncertainty around anticipated changes in the physical climate system, along with some basic biophysical impacts that would seem to be generally implied by those climate changes: based, for example, on general understanding of associations such as those between impacts and weather extremes.
A spokesperson for Australia's climate change minister Greg Combet told RTCC that they remained committed to a two way link up between their own system and Europe's in 2018.

st Order Draft, the Second Order Draft, p7, cites several papers re empirical relationships between GCR and aspects of the climate system and notes: «The forcing from changes in total solar irradiance alone does not seem to account for these observations, implying the existence of an amplifying mechanism such as the hypothesiz GCR - cloud link.»
Based on the understanding of both the physical processes that control key climate feedbacks (see Section 8.6.3), and also the origin of inter-model differences in the simulation of feedbacks (see Section 8.6.2), the following climate characteristics appear to be particularly important: (i) for the water vapour and lapse rate feedbacks, the response of upper - tropospheric RH and lapse rate to interannual or decadal changes in climate; (ii) for cloud feedbacks, the response of boundary - layer clouds and anvil clouds to a change in surface or atmospheric conditions and the change in cloud radiative properties associated with a change in extratropical synoptic weather systems; (iii) for snow albedo feedbacks, the relationship between surface air temperature and snow melt over northern land areas during spring and (iv) for sea ice feedbacks, the simulation of sea ice thickness.

The interactions between a recovering ozone hole, increasing greenhouse gases, ocean currents, and other components of the climate system must still be explored in order to better understand how the Earth's climate will change in the future.
The non-linearities are emergent properties of the complex interconnectivity of the many parts of the earth climate system — The presence and amplitude of El Nino changes the rainfall in the southeastern US, which affects evapotranspiration and cloudiness over the warm parts of the Atlantic, which affects the amount of sensible and latent heat which goes into the atmosphere, which the prevailing winds carry to Great Britain, and so on through a chain of events which eventually influence the barometric pressure differences between the Eastern and Western Pacific which drive the ENSO.
«Up to 40 % of the Amazonian forests could react drastically to even a slight reduction in precipitation; this means that the tropical vegetation, hydrology and climate system in South America could change very rapidly to another steady state, not necessarily producing gradual changes between the current and the future situation (Rowell and Moore, 2000).»
The contested IPCC statement reads: «Up to 40 % of the Amazonian forests could react drastically to even a slight reduction in precipitation; this means that the tropical vegetation, hydrology and climate system in South America could change very rapidly to another steady state, not necessarily producing gradual changes between the current and the future situation (Rowell and Moore, 2000).»
The short and lazy answer to Matthew Marler's question about the column energetics that bring the system back to equilibrium is that GCMs do of course represent evaporation, sensible heating, etc in ways that are undoubtedly imperfect (e.g., via «bulk formulas» that transfer energy down - gradient of temperature or humidity differences between the surface and air aloft), but they are free to evolve in climate change scenarios in ways that are physically self - consistent.
