"Climate Change slows Gulf Stream down"

A new PIK-study states: the Gulf Stream is slowing down. This enormous oceanic circulation system usually carries huge warm water masses to the North Atlantic and hereby determines the mild climate in Western Europe. PIK-scientist Stefan Rahmstorf about Climate Change as a suspect and possible consequences for our weather. Source: The Independent (UK), 23.03.2015.

"Double Paradox in Antarctica"

A new PIK-study shows: the Climate Change leads to more snowfall in Antarctica. Although this doesn't seem to be a dramatic trend, the heavier snow masses increase the melting of Antarctica's ice. PIK-scientist Ricarda Winkelmann explains this double paradox. Source: Frontline (India), 18.03.2015.

"Paris 2015: Is it time for a global climate deal?"

2015 UN Climate Change Conference will be held in Paris in the upcoming December. Since there is lot of controversy about the success of the 1997 Kyoto Protocol, hope is building that Paris will see an agreement to reduce greenhouse gas emissions beyond 2020, and ultimately keep global warming to below 2C. PIK-affiliated scientist Malte Meinshausen together with Anita Talberg about the negotiation process in the Summit Year 2015. Source: New Zealand Herald, 17.03.2015.

"Global warming and your weather"

A recent PIK-study points out: as the Arctic warms faster then the mid-latitudes, global warming leads to a reduced temperature difference between these regions. This results in a weaker jet stream, making the weather more persistent and promoting prolonged heat extremes. PIK-scientists Dim Coumou and Stefan Rahmstorf explain the study results and the consequences of global warming for the weather. Source: The Washington Post (USA), 12.03.2015.

"Of 'Switch-and-Choke-' or 'Tipping Points"

PIK-director Hans-Joachim Schellnhuber once pointed out the 'tipping points' as 'the Achilles heels of the Earth System', strongly impacted by climate change. About the development of this concept, the challenges of predictive science and the calculation of the safe space for humankind. Source: World Policy Journal (USA), March 2015.

"Ready for Urgent Action on Climate Change"

On world's first Divestment Day on February 13th, hundreds of events around the world called on institutions to divest from the top 200 fossil fuel companies. PIK-director Hans-Joachim Schellnhuber: "Retracting money from the fossil fuel industry could indeed become something like a world citizen movement." About the Divestment campaign and it's consequences for the economy. Source: The Guardian (UK), 13.02.2015.

"Clean Technologies and CO2 pricing"

Would a strict carbon dioxide tax work to reduce greenhouse gas emissions? Could a stronger promotion of clean technologies compensate low CO2 prices? PIK-scientist Gunnar Luderer together with PIK's chief economist Ottmar Edenhofer about deep decarbonisation, successful climate policies and the possibility to combine different approaches.

"The New Climate Normal"

Largely increased heat extremes and substantially reducted water availability - these are only some of the consequences of a global warming of two degrees. According to the PIK-report "Turn Down The Heat", that was recently released by World Bank, a loss in food security, a greater risk of social violence and spreading of diseases will be the results of climate change. This article exemplarily analyses the risks for the Arab World region. Source: BQ Doha (Qatar), 01.02.2015.

"Earth System is critically endangered"

Four of nine planetary boundaries of ecosystem stability are irreversibly crossed, a report of PIK and other research groups from nine countries resumes. About the fact that even richer nations face 'Climate Danger Zone' and the scientists' urge to redoubled efforts to rein in pollution. Source: The Washington Post (USA), 15.01.2015.

"Developing countries need to be compensated"

While an investment of annually US$ 100-150bn in low carbon technologies were necessary to aim 2C target, a future climate agreement would also need to include compensating mechansims to developing countries for part of their abatement effort, PIK-researcher Elmar Kriegler says.

"Europe capable of cutting more emissions"

While Chinas announcement to establish a nation-wide carbon-market is an extremely promising sign, Europe has more capability to reduct greenhouse-gas emissions than it pledges. PIK-scientist Brigitte Knopf about worldwide perspectives in climate policies. Source: Xinhua News Network (China), 01.12.2014.

"Save more than forests"

Changes of land-use lead to roughly one tenth of overall man-made greenhouse gas emissions, explains PIK-scientist Alexander Popp. Why forest protection alone is not enough to mitigate these emissions and why further management is necessary to aim integrated climate protection.

"We have a choice"

It's like an overweight person who is worried about their long-term health, explains PIK-economist Ottmar Edenhofer about the necessity of action to head off climate change. It's a choice as to how quickly we act, he resumes with regard to the IPCC-report 2014. Source: The Sydney Morning Herald (Australia), 04.11.2014.

"Price band for CO2 emissions is necessary"

If the ETS is to be saved, EU policymakers must take the bold step of establishing a price band for CO2 emission rights, argues Brigitte Knopf of Potsdam-Institute for Climate Impact Research (PIK) and Ottmar Edenhofer of PIK and the Mercator Research Institute on Global Commons and Climate Change (MCC).

"How to predict floods with Mathematics"

Floods and related landslides can be some of the most devastating natural disasters for populations, both in terms of immediate danger and also long term and economic impacts. PIK-scientist Niklas Boers tells BBC Science in Action about a straightforward mathematical tool that could be used to predict these heavy rainfall events.
