Urban areas account for more than 70% of CO2 emissions from burning fossil fuels. If the top 50 emitting cities were a single country, its emissions would rank third globally, behind China and the United States. In addition to playing a major role in rising atmospheric CO2 and global warming, cities are also heat islands. A heat island is formed on the one hand from waste heat emitted from cars, poorly insulated buildings and industrial plants, and on the other from heat stored and reradiated from the artificial surfaces that cover our cities.

When I initially heard about the VW scandal, it was secondhand and I hadn’t read any of the news yet, I didn’t have any of the facts. But I remember thinking (and saying), I don’t know what the big deal is about, everyone knows those chassis dynamometer tests they use for estimating emissions don’t get anywhere close to the real-world emission values. Then I read about it and saw what all the fuss was about – 35 times higher than the US limit value?! And cheating software to pass the test?!

King Coal – as the most widespread and cheapest fossil energy source is often called – is entering a crucial, maybe definitive, phase. Indeed, worldwide coal consumption has decreased significantly in recent years due to a growing hostility to the generation of electricity using unsustainable coal.

The second international Potsdam Summer School drew to a close on 23 September. Over 10 days, 40 participants from various fields and 28 different countries discussed this year’s Summer School theme, “Facing Natural Hazards”, with renowned scientists from Potsdam-based research institutes and international experts. One of those participants was Nina Köksalan. Nina studied geography, art history, philosophy and sociology and has been working for three and a half years at the Food and Agriculture Organization (FAO) of the United Nations in Rome.

When the German Foreign Office asked me in March whether I would like to become a member of the Working Group on Sustainable Arctic Development in the German Observer Delegation of the Arctic Council, of course I did not hesitate. What a splendid opportunity for an Arctic scholar to experience Arctic governance first-hand!

Rómulo Fernando Acurio Traverso is the Deputy Representative of Peru for Climate Change. In this function, he played a central role in the previous United Nations Framework Convention on Climate Change (UNFCCC) conferences and is currently preparing the 21st Conference of the Parties (COP21) in Paris this year, where 96 countries will come together to seek a deal to limit emissions to less than 2˚C above pre-industrial levels.

It was one of the most important messages to emerge from the 2014 climate negotiations in Lima: beyond the discussions of goals and time frames, we mustn’t forget to take action. When climate negotiations take place once again at the end of this year in Paris, they should serve above all to give an emphatic boost to processes towards sustainable development and globally effective climate protection. In the fight against climate change, verifiable paths need to be identified and embarked upon in a concerted way.

The IASS recently hosted a presentation titled Imagination in World Politics - Climate Change, the Mind and the Future by Manjana Milkoreit, a postdoctoral fellow at Arizona State University.

What does reforming the international monetary system have to do with saving the climate? As it happens quite a bit, says Robert Wade, Professor for Political Economy and Development at the London School of Economics. At a guest lecture at the IASS on 15 June, he described a number of proposals for reducing macroeconomic imbalances and strengthening the resilience of the international financial system.

A couple of weeks ago, I had the privilege of attending the Arctic Science Summit Week (ASSW) 2015 in Toyama, Japan, organised by the International Arctic Science Committee (IASC) and the Science Council of Japan. The event brought together nearly 700 international scientists, students, policy makers, research managers, Indigenous Peoples, and other key players with the goal of “developing, prioritizing and coordinating plans for future Arctic research”.

Recently, the Eiffel Tower in Paris was equipped with two small vertical wind turbines, which, while they spawned many news articles, have a generation capacity that is rather symbolic. In the same week, the French Parliament debated and voted on an extensive new bill laying out the country’s plans for transforming its energy supply and curbing GHG emissions.

A silent revolution is under way. In November, Dubai announced the construction of a solar energy park that will produce electricity for less than $0.06 per kilowatt-hour – undercutting the cost of the alternative investment option, a gas or coal-fired power plant.

The plant – which is expected to be operational in 2017 – is yet another harbinger of a future in which renewable energy crowds out conventional fossil fuels.

Germany aims to reduce its carbon emissions by at least 40 per cent compared to 1990 levels by the year 2020 and achieve an emissions reduction of 80 to 95 per cent by 2050. Kiel University is one of the research institutes that are already playing their part in this process.

In its most recent report, the German government’s Expert Commission on Research and Innovation criticised Germany’s feed-in tariff for renewable energy and the associated costs for electricity consumers based on two central claims. Firstly, the rapid diffusion of renewable energy – so the commission argues – has no effect on the reduction of greenhouse gas emissions.

How can ordinary people be familiarised with science? Few other researchers have devoted as much attention to this question as the Belgian atmospheric scientist Guy Brasseur. From 2009 to 2014, he was head of the Climate Service Center (CSC) in Hamburg, whose task is to communicate the latest climate research findings to politicians, scientists, and business people. Before he joined the Climate Service Center, Guy Brasseur headed the Earth and Sun Systems Laboratory in Boulder, Colorado.

Part 1 of a blog series on climate protection and structural change through participation by Katleen de Flander and Ina Richter

In recent weeks, the issue of climate protection has been high on the national and international political agenda. At international level, participants at the UN Climate Conference in Lima last week laid the foundations for a global climate agreement that is due to be concluded next year in Paris.
