==State of Climate Science==

My first lecture will provide an overview of the latest results of climate
science. I will start out by putting some of the recently observed climatic
extremes into context. Consequently, I will talk about new projections of sea
level rise, the decrease in land and sea ice, and some of the often overlooked
consequences of ocean acidification. I will also provide an update on tipping
elements in the Earth System and present some preliminary research on
the possibility of reaching a global tipping point, i.e., triggering a runaway
greenhouse effect. Last but not least, some basic scientific facts about
climate change will be discussed that highlight the urgency of the problem.

==State of Climate Economics and Policy==
My second lecture will deal with the economic and political dimensions
of climate change. I will discuss the technical and economic feasibility of
confining global temperature rise to 2°C above pre-industrial levels. Various
approaches will be presented, which – if fully implemented – could provide
a way to (still) avoid dangerous climate change. These will be contrasted
with outcomes of the Copenhagen Conference and the current state of
international climate change negotiations.

==Tragic Triumph: Cassandra, Pascal and the IPCC==
 
Climate science has been under a lot of attack recently. In my third lecture, I will revisit the various attempts to discredit climate scientist of the recent past. In particular, I will talk about the repercussions of the CRU E-mails theft and the errors discovered in the last IPCC assessment report. A Part of my lecture will also deal with ideas on reforming the IPCC, recent changes in public opinion about climate change and the dubious role of the media. Finally, drawing on the Cassandra mythos and Pascal’s wager, I argue that the best that climate science can expect is a tragic triumph.
