German Science Hour: Täglich eine Stunde Wissenschaft

Das Klimaabkommen von Paris war ein wichtiger Meilenstein für die Klimaforschung. Sie hat die Wissensgrundlagen geschaffen und spielt nun eine entscheidende Rolle, um die Ziele des Abkommens zu erreichen.

Das BMBF brachte deshalb die Klimaforschung ins Herz der Verhandlungen bei COP23 und veranstaltete täglich im Deutschen Pavillon die German Science Hour. Fachleute aus Wissenschaft, Politik und Gesellschaft ...width=180

... präsentierten aktuelle wissenschaftliche Fakten über den Klimawandel
... erklärten Forschungsergebnisse auf verständliche Weise
... standen dem Publikum Rede und Antwort

Das Spektrum der German Science Hour reichte von naturwissenschaftlichen, gesellschaftlichen und wirtschaftlichen Aspekten bis hin zu Klimakommunikation in Zeiten von fake news.

Science of extreme events
It is difficult to feel and experience climate change, but extreme events such as heat waves, floods, droughts make it to the news headlines. How does climate change influence such extremes? What can we do to avoid dangerous impacts?

Climate of the past - climate of the future
The climate has always changed, but the current change is not caused by natural reasons, is much faster and poses high risks for human welfare. What happened in the past to ecosystems and humans? Why is the current change different? How will the Earth system develop in the future? What are the implications of the Paris Agreement?

Communicating climate science
Despite the scientific facts on climate change large parts of the public are not aware of the associated risks and the need for transformational change. Many think that climate change is a matter of believe and do not trust the science. How can science communication be improved? What are dos and donts when talking to different target audiences?

The fate of greenhouse gases: the knowns and the unknowns
Greenhouse gas emissions are highest in human history and rising concentrations are changing the climate, as well as heating and acidifying the oceans. What do we know about the carbon cycle? Which methods are used to observe greenhouse gas fluxes from land, ocean, and in the atmosphere? How can we detect the human signal?

Carbon pricing: making polluters pay or selling out our future?
Carbon pricing, in the form of carbon taxes and cap & trade schemes, is becoming a pillar of climate policy around the world. Recently it has been argued that it could also help to overcome the cooperation problem at the global level. At the same time, concerns about effectiveness, persistently low prices, interactions with other instruments and distributional effects continue to grow. The session aims at giving an interdisciplinary perspective on the strength and limits of carbon pricing in the pursuit of a low-carbon and inclusive future.

Our ocean future: marine ecosystems under climate change
Climate change poses multiple risks for the oceans: increasing acidification, warming and deoxygenation affect marine ecosystems, which are already threatened by marine litter. At the same time a substantial fraction of the global population depends on fishery for their livelihoods. The event will provide insights in risks of the multiple changes in the oceans and possible consequences for society.

Science in times of fake news
Science and the IPCC in particular have identified the problem of climate change and the challenges involved to tackle this problem. The UNFCCC and the Paris Agreement are committed to be science-based, but important countries and stakeholder deny the facts. The event will discuss the role of science for climate policy as well as different forms of scepticism and ways to address these.

Paris, coal, and the price of carbon
Keeping global temperature rise below 2°C or 1.5°C requires highly ambitious mitigation actions by all countries such as the immediate phase-out of coal and avoiding carbon-intensive infrastructures. Yet, global cooperation is challenged by to-date inadequate credibility of Nationally Determined Contributions, increasing concerns around national competitiveness, regional development, and the renaissance of cheap coal. This German Science Hour will explore options to implement the global Energiewende with a specific view to the role of international carbon pricing.

Transformation - turning the climate tide
Hans Joachim Schellnhuber, Director of the Potsdam Institute for Climate Impact Research: “We must end the Dictatorship of Now – our culture of short-term convenience that comes at the expense of the live chances of future generations. In poorer countries in particular, droughts, floods or hurricanes can trigger entire cascades of impacts. Agriculture and health are affected, and of course this has consequences for migration both regionally and globally.”
Today’s young people are the ones to be confronted with the devastating effects of climate change in the near future. Consequently, we must integrate their perspectives into the debate about tackling the climate problem. This “Dialogue with the Young Generation” offers the opportunity to get to hear voices from people in their Twenties, from three different continents, discussing with one of the most renowned scientists who has been investigating the climate for more than a quarter of a century.

Failing the carbon budget - what's next?
A large fraction of emitted CO2 remains in the atmosphere for centuries, and any amount of warming can be closely associated with a certain carbon budget. To stop global warming, emissions must go to net zero. How much CO2 and other greenhouse gases can we still emit and keep global warming below 1.5°C, 2°C or 3°C? What are the options if we fail to reduce emissions fast enough? The event will address technology options from a scientific, social and political perspective as well as the risks and benefits of technology options vs. transformation.
