Prof. Dr. Mathias Rotach
(Professor for Dynamic Meteorology at the University of Innsbruck, Institute of Atmospheric and Cryospheric Sciences): The world is not flat – implications for the global Carbon balance

Abstract: Among the processes contributing to the global CO2 budget, net uptake by the land surface bears the largest uncertainty. Therefore, the land sink is often estimated as the residual from the other terms that are known with greater certainty.  On average over the last decades the difference between modelled land surface uptake and this residual is negative, thus suggesting that the different modelling approaches miss an important part in land-atmosphere exchange. Based on experience with atmospheric modelling at high-resolution, it is argued that this discrepancy is likely due to missed meso-scale (thermally or dynamically forced) circulations in complex terrain. Noting that more than 50% of the land surface qualifies as complex terrain, the contribution of meso-scale circulations is hypothesized to alleviate at least partly the uncertainty in the modelled land surface uptake. In this presentation, ‘Carbon’ is only used as an example. In fact, mass exchange in general, but also momentum and energy exchange over complex mountainous terrain is largely affected. The need for a better understanding of these processes will be discussed and current activities will be introduced.

Keynote Talk
Prof. Dr. Karen Pittel (Faculty of Economics, LMU München & Ifo Center for Energy, Climate and Exhaustible Resources)
"Climate policy from a global perspective - A look at costs, benefits and post-paris challenges"

Wherever decisions have to be made under scarcity, economists aim to determine the costs and benefits associated with these decisions. While this may be (relatively) uncomlicated where individual investment decisions are concerned, estimating the costs and benefits of climate protection are unsurprisingly a thousand fold more complex.
Following a brief introduction to the current state of global climate policy and challenges related to reaching the 1.5°C target, this talk offers a first take on the principles and difficulties involved in putting a monetary value on climate protection efforts. These difficulties result in vastly diverging cost and benefit estimations. Studies have, for example, put the social costs of emitting a ton of carbon in the range from scarcely US$ 7 to an astonishing US$ 2400. While both values are, admittedly, outliers, they reflect very well the magnitude to which cost estimates depend on methodology, assumptions and calibration.
