The Role of Market Mechanisms in a Post-2020 Climate Change Agreement. CEPS Special Report No. 87/May 2014

This special report is intended to serve as a background briefing document for the European Climate Platform seminar on Carbon Markets in the 2015 Agreement: Role and Architecture, but also raises issues of more enduring relevance in the wider debate about market mechanisms and the next climate change agreement. The paper looks at the relationship between the carbon market and a new climate change agreement, to be finalised in Paris in 2015. It tries to answer two key questions: does the carbon market have a role to play in a post-2020 agreement, and what is the role of a post-2020 agreement in the creation and operation of a carbon market? Introduction. The world has changed in many ways since 1997 when the Kyoto Protocol was adopted, along some critical axes, both from an economic and emissions points of view. Moreover, and this cannot be quantified, the appetite for global governance, especially for an agreement with such far-reaching implications as a climate change agreement, has diminished considerably. This paper looks at the relationship between the carbon market and a new climate change agreement, to be finalised in Paris in 2015. It tries to answer two key questions: does the carbon market have a role to play in a post-2020 agreement, and what is the role of a post-2020 agreement in the creation and operation of a carbon market?

Surface velocity fields, digital elevation models and ice front positions derived from multi-mission SAR remote sensing data at Sjögren Inlet glaciers, Antarctic Peninsula

Substantial retreat or disintegration of numerous ice shelves have been observed on the Antarctic Peninsula. The ice shelf in the Prince Gustav Channel retreated gradually since the late 1980's and broke-up in 1995. Tributary glaciers reacted with speed-up, surface lowering and increased ice discharge, consequently contributing to sea level rise. We present a detailed long-term study (1993-2014) on the dynamic response of Sjögren Inlet glaciers to the disintegration of Prince Gustav Ice Shelf. We analyzed various remote sensing datasets to observe the reactions of the glaciers to the loss of the buttressing ice shelf. A strong increase in ice surface velocities was observed with maximum flow speeds reaching 2.82±0.48 m/d in 2007 and 1.50±0.32 m/d in 2004 at Sjögren and Boydell glaciers respectively. Subsequently, the flow velocities decelerated, however in late 2014, we still measured about two times the values of our first measurements in 1996. The tributary glaciers retreated 61.7±3.1 km² behind the former grounding line of the ice shelf. In regions below 1000 m a.s.l., a mean surface lowering of -68±10 m (-3.1 m/a) was observed in the period 1993-2014. The lowering rate decreased to -2.2 m/a in recent years. Based on the surface lowering rates, geodetic mass balances of the glaciers were derived for different time steps. High mass loss rate of -1.21±0.36 Gt/a was found in the earliest period (1993-2001). Due to the dynamic adjustments of the glaciers to the new boundary conditions the ice mass loss reduced to -0.59±0.11 Gt/a in the period 2012-2014, resulting in an average mass loss rate of -0.89±0.16 Gt/a (1993-2014). Including the retreat of the ice front and grounding line, a total mass change of -38.5±7.7 Gt and a contribution to sea level rise of 0.061±0.013 mm were computed. Analysis of the ice flux revealed that available bedrock elevation estimates at Sjögren Inlet are too shallow and are the major uncertainty in ice flux computations. This temporally dense time series analysis of Sjögren Inlet glaciers shows that the adjustments of tributary glaciers to ice shelf disintegration are still going on and provides detailed information of the changes in glacier dynamics.
