NDR Serie salty FiSH: „Klimawandel in SH – Die Kelpwälder vor Helgoland“

Philipp Jeß und Jonas Drescher (NDR Forschungstaucher), Video 20 min

In der 1. Folge ihrer neuen NDR Doku-Serie „salty FiSH“ beschreiben die beiden NDR Autoren in „Klimawandel in SH: Die Kelpwälder vor Helgoland“, wie Forscher:innen des Verbundes „sea4soCiety“ der deutschen Forschungsmission CDRmare mit verschiedenen Methoden (u.a. Video, Hydroakustik, Drohne, Fernerkundung) die Verbreitung der großen Braunalgen vor Helgoland erstmals großflächig kartieren. Ein weiteres Thema ist die Analyse von Wasserproben, um herauszufinden, was mit dem gelösten Kohlenstoff passiert, den der Kelp in seine Umgebung abgibt.  Längerfristig soll erforscht werden, unter welchen Bedingungen die Wiederaufforstung von Tangwäldern in der Nordsee am erfolgreichsten wäre, um die CO2-Aufnahmekapazität zu erhöhen.

The public must be assured that potential leakages from storage reservoirs can be detected and that therefore the CO2 is safely contained. The authors conducted a controlled release of 675 kg CO2 within sediments at 120 m water depth, to simulate a leak and test novel detection, quantification and attribution approaches. The authors show that even at a very low release rate (6 kg day⁻¹), CO2 can be detected within sediments and in the water column. Alongside detection the authors show the fluxes of both dissolved and gaseous CO2 can be quantified. The CO2 source was verified using natural and added tracers. The experiment demonstrates that existing technologies and techniques can detect, attribute and quantify any escape of CO2 from sub-seabed reservoirs as required for public assurance, regulatory oversight and emissions trading schemes.

To Remove CO2 From the Atmosphere, Imagine the Possibilities

by Richard Press on nist.gov (official website of the United States government)

„Computer simulation methods from NIST help speed up the search for carbon capture materials.[…] NIST scientists use computer simulations that calculate a potential capture material’s affinity for CO2 relative to other gases in the atmosphere. That allows them to predict how well the capture material will perform. The simulations also generate images that show how carbon capture works on a molecular scale.“

Flooding Wetlands Could Be the Next Big Carbon Capture Hack

by Bianca Nogrady on wired.com

„The Nywaigi people in Australia have discovered a way to sequester carbon, boost coastal biodiversity, and create jobs. […] In addition to boosting ecotourism, the revitalized wetlands are providing a unique opportunity for the development of a carbon credit business. Restoring Mungalla’s native landscape sequesters carbon dioxide both through reforestation on land and in the soils and sediments of the wetlands and mangroves. That sequestered carbon can be accounted for and then traded on the carbon markets as credits to offset emissions elsewhere.“

We must fundamentally rethink “net-zero” climate plans. Here are six ways.

by James Temple on MIT technologyreview.com

„Corporate climate plans are too often a mix of fuzzy math, flawed assumptions, and wishful thinking. […] Numerous studies and analyses have highlighted serious problems with the plans from many large companies to achieve what’s known as carbon neutrality or net-zero emissions. […] It’s time to stop that. (Even HBO’s John Oliver has taken to ridiculing offsets on his show.) Going forward, the purchase of such credits should at best be thought of as an act of climate philanthropy, but not as a realistic method for scratching off tons of emissions from corporate carbon ledgers. […] Here are six ways that companies can take real steps to tackle their pollution and help get industries on track to make much faster progress in the coming years.“
