In this comprehensive research report, we undertake an extensive examination of one of the most transformative biological discoveries of the modern scientific era. For centuries, the foundational dogma of terrestrial ecology was absolute: the sun was the ultimate and singular source of energy capable of sustaining complex life.

Not all giant icebergs, or "megabergs," release fertilizing nutrients into the ocean as they melt; their capacity to stimulate marine life and absorb atmospheric carbon varies drastically depending on their individual life cycles and histories.

Rivers worldwide are progressively warming and losing oxygen, a transformation that turns them into significant, under-accounted sources of greenhouse gases (GHGs). The influx of agricultural and urban nutrients, combined with rising temperatures, fuels microbial activity that releases carbon dioxide, methane, and nitrous oxide into the atmosphere.

The reintroduction and activity of beavers in river corridors transform headwater streams into expansive wetlands that function as highly efficient, long-term carbon sinks. By naturally flooding landscapes and altering groundwater flows, beavers facilitate the extensive trapping of both organic and inorganic carbon materials.

We were happy to welcome MSc and BSc students from Wageningen University & Research to the Max Planck Institute for Meteorology in Hamburg yesterday. 🌍

Through presentations on #ClimateModeling, ocean #biogeochemistry, and #cloud observations, the students got an inside look at our research. In small-group discussions with early-career scientists, they could also ask questions about PhDs and careers in #ClimateScience. We finished the visit with a rooftop view over Hamburg 📸

The unprecedented surge in #atmospheric #methane during the early 2020s was primarily driven by a temporary decline in #hydroxyl (OH) radicals, which reduced the atmosphere's ability to break down the gas, coupled with increased natural emissions from wetlands due to wetter #climate conditions.

Edward Smith Deevey Jr. (3 December 1914 – 29 November 1988), born in #AlbanyNewYork, was a prominent American #ecologist and #paleolimnologist, and an early protégé of #GEvelynHutchinson at #YaleUniversity. He was a creative pioneer in several areas, including quantitative #palynology, cycling of natural #isotopes, #biogeochemistry, #populationDynamics, #systematics and #ecology of freshwater #zooplankton, and he promoted the use of life tables in ecology. In 1938.

7.8: Why Do These Cancelled Science Grants Matter?

In this episode, Christina talks to Dr Gabriel Filippelli - one of the first scientists to have a running project canceled by the Trump administration. This fascinating interview reveals just how important internationally these American grants can be, and Dr Filippelli passionately describes this unprecedented attack on science and education and what we all lose when the work that scientists do grinds to a halt or is extremely politically curtailed. It's important, he tells us, to support the institutions that you care about and are vital to the continued knowledge of how to survive our climate-changed future.

Dr Filippelli is the Chancellor’s Professor of Earth Sciences at Indiana University Indianapolis and the Executive Director of the Indiana University Environmental Resilience Institute. He works at the junction between biogeochemical cycles, climate change, and human health.

Dr Filippelli has also written the book Climate Change and Life: The Complex Co-evolution of Climate and Life on Earth, and Beyond, which explores Earth's ecological resilience to the great changes in climate that have occurred over the history of the Earth. He was also part of the driving force behind Climate Change and Resilience in Indiana and Beyond, which details local efforts to reduce the risks and lessen the harmful impacts of climate change, as well as prepare for the unavoidable consequences of climate change.

Congratulations to both!

The Bog Brush was handed on to Bristol so we'll see you in 2025 for #BOGS2025.
