Gregor Hagedorn (born 1965) is a German botanist and academic director at the Natural History Museum, Berlin. [1]
Gregor Hagedorn studied biology at the University of Tübingen and at Duke University (North Carolina). [3] Afterwards, he worked in the Department of Mycology at the University of Bayreuth until 2007. [4] In 2007 his dissertation on "Structuring Descriptive Data of Organisms – Requirement Analysis and Information Models" was completed at the University of Bayreuth. [5]
From 1992 to 2013 he was a staff member at the Federal Biological Research Centre for Agriculture and Forestry, now Julius Kühn Institute. [3] He played a major role in the development of a data standard for describing gender within the Taxonomic Databases Working Group. [6]
Since 2013, Hagedorn has been working at the Museum of Natural History Berlin, first as Head of Digital World and Information Science (until 2016), then as Academic Director. [7] [8]
Between 2014 and 2018 Hagedorn was a member of the German National Council for Information Infrastructures as a representative of the scientific organisations.
Together with other scientists, Hagedorn founded the grassroots movement Scientists for Future (S4F) in March 2019. [9] [10] [11] This initiative was inspired by a group of Belgian scientists who had earlier offered their support to the nascent Fridays for Future movement in January 2019 under the banner of Scientists for Climate. [12] [13] [14] The first statement by Scientists For Future was written by a circle of 30 people and signed by 26800 scientists in Germany, Switzerland, and Austria. [14] The key authors also published a similar statement in Science with scientists from the United States, including Michael Mann and Katharine Hayhoe. [15] Hagedorn represented Scientists for Future at an environmental meeting with the German Federal President Frank-Walter Steinmeier in early 2020. [16] In late‑2021, Hagedorn presented a TEDx talk in Potsdam on the topic of sustainability. [17]
Dansgaard–Oeschger events, named after palaeoclimatologists Willi Dansgaard and Hans Oeschger, are rapid climate fluctuations that occurred 25 times during the last glacial period. Some scientists say that the events occur quasi-periodically with a recurrence time being a multiple of 1,470 years, but this is debated. The comparable climate cyclicity during the Holocene is referred to as Bond events.
RealClimate is a commentary site (blog) on climatology. The site's contributors include climate scientists whose goal is to provide a response to developing stories and a context they feel is sometimes missing in mainstream commentary on climate science and climate change. The forum is moderated, and is restricted to scientific topics to avoid discussion of political or economic implications of the science. RealClimate was launched on 10 December 2004 by nine climate scientists.
Climate sensitivity is a measure of how much Earth's surface will warm for a doubling in the atmospheric carbon dioxide concentration. In technical terms, climate sensitivity is the average change in global mean surface temperature in response to a radiative forcing, which drives a difference between Earth's incoming and outgoing energy. Climate sensitivity is a key measure in climate science, and a focus area for climate scientists, who want to understand the ultimate consequences of anthropogenic global warming.
Stefan Rahmstorf is a German oceanographer and climatologist. Since 2000, he has been a Professor of Physics of the Oceans at Potsdam University. He studied physical oceanography at Bangor University and received his Ph.D. in oceanography from Victoria University of Wellington (1990). His work focuses on the role of ocean currents in climate change. He was one of the lead authors of the IPCC Fourth Assessment Report.
Johannes Daniel Dahm is a German geographer, ecologist, activist, consultant and entrepreneur.
The Atlantic meridional overturning circulation (AMOC) is part of a global thermohaline circulation in the oceans and is the zonally integrated component of surface and deep currents in the Atlantic Ocean. It is characterized by a northward flow of warm, salty water in the upper layers of the Atlantic, and a southward flow of colder, deep waters. These "limbs" are linked by regions of overturning in the Nordic and Labrador Seas and the Southern Ocean, although the extent of overturning in the Labrador Sea is disputed. The AMOC is an important component of the Earth's climate system, and is a result of both atmospheric and thermohaline drivers.
Gerhard Scherhorn was a German Professor and economist.
Julius Kühn-Institut – Bundesforschungsinstitut für Kulturpflanzen (JKI) is the German Federal Research Centre for Cultivated Plants. It is a federal research institute and a higher federal authority divided into 15 specialized institutes. Its objectives, mission and research scope were determined by section 11, paragraph 57 of the 1987 Federal Law on the Protection of Cultivated Plants as subsequently amended.
Hans Joachim "John" Schellnhuber is a German atmospheric physicist, climatologist and founding director of the Potsdam Institute for Climate Impact Research (PIK) and former chair of the German Advisory Council on Global Change (WBGU).
Katherine Richardson Christensen is Professor in Biological Oceanography, leader of the Sustainability Science Centre and a principal investigator for the Center for Macroecology, Evolution and Climate at the University of Copenhagen. She was the vice dean of the Faculty of Science from 2007–2012. Her research focuses on the importance of biological processes in the ocean for the uptake of carbon dioxide from the atmosphere and how ocean biology, including diversity, contributes to ocean function in the Earth System.
The cold blob in the North Atlantic describes a cold temperature anomaly of ocean surface waters, affecting the Atlantic Meridional Overturning Circulation (AMOC) which is part of the thermohaline circulation, possibly related to global warming-induced melting of the Greenland ice sheet.
A carbon budget is a concept used in climate policy to help set emissions reduction targets in a fair and effective way. It looks at "the maximum amount of cumulative net global anthropogenic carbon dioxide emissions that would result in limiting global warming to a given level". When expressed relative to the pre-industrial period it is referred to as the total carbon budget, and when expressed from a recent specified date it is referred to as the remaining carbon budget.
Peter Kalmus is an American scientist and writer based in Altadena, California. He is a data scientist at NASA's Jet Propulsion Laboratory as an associate project scientist at UCLA's Joint Institute for Regional Earth System Science & Engineering.
School Strike for Climate, also known variously as Fridays for Future (FFF), Youth for Climate, Climate Strike or Youth Strike for Climate, is an international movement of school students who skip Friday classes to participate in demonstrations to demand action from political leaders to prevent climate change and for the fossil fuel industry to transition to renewable energy.
Scientists for Future (S4F) is an international environmental initiative founded by a group of scientists in Germany, Austria, and Switzerland in support of the student movement Fridays for Future (FFF).
A climate target, climate goal or climate pledge is a measurable long-term commitment for climate policy and energy policy with the aim of limiting the climate change. Researchers within, among others, the UN climate panel have identified probable consequences of global warming for people and nature at different levels of warming. Based on this, politicians in a large number of countries have agreed on temperature targets for warming, which is the basis for scientifically calculated carbon budgets and ways to achieve these targets. This in turn forms the basis for politically decided global and national emission targets for greenhouse gases, targets for fossil-free energy production and efficient energy use, and for the extent of planned measures for climate change mitigation and adaptation.
Amita Kuttner is a Canadian astrophysicist and politician who served as the interim leader of the Green Party of Canada from November 24, 2021 to November 19, 2022. Kuttner first ran for office in the 2019 federal election, seeking a House of Commons seat as a Green candidate, followed by a run for Green Party leadership in 2020 following the election. They are the first transgender person and the first person of East Asian descent to lead a federal party in Canada.
Ulrike Lohmann is a climate researcher and professor for atmospheric physics at the ETH Zurich. She is known for her research on aerosol particles in clouds.
Joeri Rogelj is a Belgian climate scientist working on solutions to climate change. He explores how societies can transform towards sustainable futures. He is a Professor in Climate Science and Policy at the Centre for Environmental Policy (CEP) and Director of Research at the Grantham Institute – Climate Change and Environment, both at Imperial College London. He is also affiliated with the International Institute for Applied Systems Analysis. He is an author of several climate reports by the Intergovernmental Panel on Climate Change (IPCC) and the United Nations Environment Programme (UNEP), and a member of the European Scientific Advisory Board for Climate Change.
In diesem Sinn entstand im März 2019 der Verbund »Scientists for Future«, den der Botaniker Gregor Hagedorn angestoßen hat. [It was with this in mind that the Scientists for Future network, initiated by botanist Gregor Hagedorn, came into being in March 2019.]
