On Mars or Earth, biohybrid can turn carbon dioxide into new products

Bacteria on nanowires convert sunlight, carbon dioxide and water to organic building blocks University of California – Berkeley If humans ever hope to colonize Mars, the settlers will need to manufacture on-planet a huge range of organic compounds, from fuels to drugs, that are too expensive to ship from Earth. University of California, Berkeley, and…

Fungal decisions can affect climate

American Society of Agronomy Fungi play an important role in the ecosystem by decomposing plant and animal debris into nutrients and simpler compounds. Credit Susan V. Fisk When we think of climate change, we tend to think about greenhouse gases, fossil fuels and pollution. Most of us don’t think about fungi. But Kathleen Treseder does.…

Negative CO2 Emissions

by Kevin Kilty An article in the January 2020 Issue of Physics Today (1) presents an interesting and very readable overview of methods to capture and store away CO2 emissions. The purpose of this guest blog is to summarize a few key points the paper makes, and add some commentary. WUWT has covered some of…

Carbon Sequestration

Guest post by Rud Istvan, As most WUWT readers know, the issue of carbon sequestration is an important but largely IPCC undiscussed ‘anthropogenic global warming’ question. I got to thinking about it again as a result of the Australian brush fires that are dramatically releasing sequestered brush carbon. And it has been years since the…

E. coli bacteria engineered to eat carbon dioxide

What could go wrong? ~cr From Nature Feat could turn bacteria into biological factories for energy and even food. The bacterium Escherichia coli has been engineered to grow by consuming carbon dioxide.Credit: Steve Gschmeissner/SPL E. coli is on a diet. Researchers have created a strain of the lab workhorse bacterium — full name Escherichia coli…

Department of Energy Announces $43 Million to Develop Carbon Capture and Storage Technology

From Energy.gov November 14, 2019 WASHINGTON, D.C. – Today, the U.S. Department of Energy’s (DOE) Advanced Research Projects Agency-Energy (ARPA-E) announced up to $43 million in funding to develop carbon capture and storage (CCS) technologies that enable power generators to be responsive to grid conditions in a high variable renewable energy (VRE) penetration environment. The…

2017 NOAA Study Authors Recommended Fewer Controlled Burns, Because Climate Change

Guest essay by Eric Worrall According to the study authors, frequent controlled burns reduce the ability of some forests to sequester CO2. More frequent fires reduce soil carbon and fertility, slowing the regrowth of plantsLong-term effects of repeated fires on soils found to have significant impacts on carbon storage not previously considered in global greenhouse…

Plants and fungi together could slow climate change

International Institute for Applied Systems Analysis A new global assessment shows that human impacts have greatly reduced plant-fungus symbioses, which play a key role in sequestering carbon in soils. Restoring these ecosystems could be one strategy to slow climate change. Human-induced transformations of Earth’s ecosystems have strongly affected distribution patterns of plant-fungus symbioses known as…
