SPECIAL: IPCC report on 1,5°C: Unprecedented transformation needed to reach climate targets

Arctic Sea IceLimiting global warming to 1.5° Celsius would require rapid, far-reaching and unprecedented changes in all aspects of society, says a new detailed assessment by the Intergovernmental Panel on Climate Change (IPCC). Ninety-one authors and review editors from 40 countries were involved in preparing the report, among them Elmar Kriegler from the Potsdam Institute for Climate Impact Research (PIK) who is one of the lead authors for the key chapter on mitigation pathways. The Special Report on Global warming of 1.5°C will be an important scientific input into the UN climate summit in Poland in December and was prepared in response to an invitation from the United Nations Framework Convention on Climate Change when the historic Paris Agreement was adopted in 2015.

Record warm years almost certainly due to human-made climate change

Record warm years almost certainly due to human-made climate change

01/25/2016 - Recent record warm years are with extremely high likelihood caused by human-made climate change. Without greenhouse-gas emissions from burning coal and oil, the odds are vanishingly small that 13 out of the 15 warmest years ever measured would all have happened in the current, still young century. These odds are between 1 in 5000 and 1 in 170.000, a new study by an international team of scientists now shows. Including the data for 2015, which came in after the study was completed, makes the odds even slimmer.

New top German IPCC scientist visits PIK

New top German IPCC scientist visits PIK

2016/01/25 - The newly elected top German scientist in the Intergovernmental Panel on Climate Change (IPCC), Hans-Otto Pörtner, visited the Potsdam Institute (PIK) this week for an intense exchange about challenges of the next climate science assessment report. It will be the sixth of its kind and due in 2022. Pörtner, a senior biologist at the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven, heads the part of the report assessing climate change impacts. This is a core research issue of PIK. What is more, for half a decade PIK’s chief economist was head of the IPCC’s working group on mitigation.

01/14/2016 - The Ambassador of the United States to Germany, John B. Emerson, visited the Potsdam Institute for Climate Impact Research (PIK) this week to discuss the consequences of the recent UN summit in Paris. Following a meeting behind closed doors with PIK director John Schellnhuber, the high-ranking guest gave a talk to researchers and students. Both the Ambassador and the PIK director highlighted the urgency of achieving further progress towards effective climate stabilization.

Human-made climate change suppresses the next ice age

Human-made climate change suppresses the next ice age

01/13/2016 - Humanity has become a geological force that is able to suppress the beginning of the next ice age, a study now published in the renowned scientific journal Nature shows. Cracking the code of glacial inception, scientists of the Potsdam Institute for Climate Impact Research found the relation of insolation and CO2 concentration in the atmosphere to be the key criterion to explain the last eight glacial cycles in Earth history. At the same time their results illustrate that even moderate human interference with the planet’s natural carbon balance might postpone the next glacial inception by 100.000 years.

Historic climate agreement: “The spirits of Paris have defeated the ghosts of Copenhagen"

Historic climate agreement: “The spirits of Paris have defeated the ghosts of Copenhagen"

12/14/2015 - 195 states worldwide adopted a breakthrough climate agreement at the UN climate summit in Paris, COP21. Leading scientists from the Potsdam Institute for Climate Impact Research actively participated in the historic meeting that put the world on the path to limiting global warming to well below 2 degrees Celsius and bring down greenhouse-gas emissions to net zero within a few decades. While implementing the treaty will be an enormous challenge, for the first time ever climate stabilization and hence limiting climate risks including weather extremes and sea-level rise comes into reach. It is the beginning, not the end, of a process that now requires rapid implementation strong policy instruments that live up to the aspirations of the agreement.
