Clouds Less Climate-sensitive Than Assumed

Media Reports & Press Releases |

Airborne Campaign Solves Parts of the Riddle of Clouds Cumulus clouds in trade-wind regions cover nearly 20 percent of our planet, producing a cooling effect. Until recently, it was assumed that global warming would reduce the surface covered by these clouds, amplifying the warming. However, a team around Dr. Raphaela Vogel from Universität Hamburg was

Die dras­ti­sche Er­wär­mung der Ark­tis und ih­re ge­mein­schaft­li­che Er­for­schung

Media Reports & Press Releases |

Im Frühjahr 2022 fand die großangelegte Forschungskampagne HALO-(AC)³ in der Arktis ausgehend von Kiruna/Nordschweden und Ny-Ålesund/Spitzbergen statt. Mehr als 100 Wissenschaftlerinnen und Wissenschaftler, 3 Forschungsflugzeuge, Ballon und Bodenmessstationen waren im Einsatz, um die arktische Verstärkung, die immer rasantere Erwärmung der Arktis, in Zeiten des Klimawandels zu erforschen. Dabei schauten die Forschungsteams besonders auf die nordwärts gerichteten Warmlufteinschübe

Bremen Participates in Research Flights over Canada

Media Reports & Press Releases |

Methane is produced by oil and gas extraction, coal mining, landfills, farming, wetlands, and thawing permafrost areas. But what are the exact numbers for each source? To find out, the HALO research aircraft has been operating over Canada – with researchers from the University of Bremen on board. “Methane in the Earth’s atmosphere is considered

Re­search flights over Cana­da anal­yse green­house gas­es

Media Reports & Press Releases |

Coal mining, oil and gas production, landfill and agriculture are all anthropogenic sources of the greenhouse gas methane, which is the second most important contributor to climate change after carbon dioxide. A methane molecule has an up to 86 times stronger climate impact than carbon dioxide. This is compounded by Earth’s large wetlands and thawing

Smoke from the Black Summer wildfires in Australia impacted the climate and high altitude winds of the southern hemisphere for more than a year and a half

Media Reports & Press Releases |

TROPOS analysis: Wildfire smoke becomes increasingly important for climate models due to climate change The 2019/20 wildfires in Australia transported more smoke into the atmosphere than observed ever before anywhere in the world. In the so-called Black Summer, three times as many particles reached high air layers as in the previous record wildfires in Canada
