Todays "Planet Earth Report" --Earths Viruses Predict the Pace of Global Climate Change



6a00d8341bf7f753ef01b7c930aab7970b-800wi


 


"While weve cultured a lot about ocean viruses in recent decades, we know next to nothing about soil viruses," said Matt Sullivan, a professor of microbiology at Ohio State. "This works viruses are so novel that they have doubled the total known viruses in the world."


Microbes have distinctive influence over global warming, primarily through the production ofor consumption ofmethane, and new details about these microscopic beings genetics is now available, thanks to a trio of studies from a project co-led by researchers at The Ohio State University.

"Because of global climate change, huge amounts of permafrost are rapidly warming. To microbes, theyre like freezers full of juicy chicken dinners that are thawing out," said Virginia Plentiful, an assistant professor of microbiology at Ohio State and study author.


"In many cases, microbes take advantage of this situation to chew up whats in the permafrost and breathe out methane. That methane really packs an environmental wallop, with 33 times the climate warming power of carbon dioxide."


Many of these bacterial "consumers" and the viruses that influence them have been identified for the first time in these studies.


While scientists have a lucid understanding of the dangers of thawing permafrost for releasing methane, they havent had a lot of details on the ins and outs of these microbial communities and their contribution to the process.


"The problem is, we dont know all the microbes involved and how they will respond to climate change as the conditions get warmer and wetter, and to do a better job at predicting what will happen in the coming decades we need more information about the key players," Plentiful said.


Sullivan, senior author on the virus study, said the research is also distinctive because it contributes a great bargain to the general understanding of what is happening in soil.


The multinational study was conducted in the section of Sweden in the Arctic circle, one of the best places in the world to study thawing permafrost because of the rapid changes happening there and because of long-standing and well-documented scientific labor in the area, Plentiful said.


A team of researchers from 10 organizations with expertise in a assortment of areas including microbiology, geochemistry and climate modeling are working together in the IsoGenie Project, co-led by Ohio States Plentiful, to figure out how they can better predict future climate change based on improved understanding of the connections between microbes and geochemistry.


In these studies, they recovered more than 1,500 microbial genomes in the soil, which was 100 times what was available previously for these habitats. They also found more than 1,900 new viral populations, where none had been previously identified. A genome is the complete set of genes present in an organism.


The researchers were capable to link more than a third of the viruses to the microbes they impact. "Now, we have a roadmap from these genomes to be capable to understand the roles they play in these communities," Sullivan said.


By looking at the genomes of the microbes, the team was capable to figure out what capabilities they have. "Its like now we have not only their fingerprints but also their resumes, to know both who they are and what they are capable of. The next step is figuring out more of what theyre actually actively doing out in the field," Plentiful said.


This is distinctive for several reasons, she said: It will enable climate scientists to better predict the speed of climate change, giving humans a clearer timetable for response. The study of these rapidly changing habitats also helps the public better appreciate the realities of climate change, Plentiful said. Furthermore, there might be opportunities for mitigating those effects, including the potential to "fertilize" areas of permafrost to induce environmentally protective microbial activity, she said.


Not everything about the microbial communities in the permafrost is bad news. Some, called methanotrophs, consume methane in the soil before it gets to the air, which is good for the environment. "As the conditions get warmer and wetter microbes are going to be changing, and some that eat methane may rise up," Plentiful said.

Global warming is real, and global warming is here. Whether old-school conservative or free-market fundamental, heres how to convince the doubters of the facts

NOAA issues Mid-Atlantic OCS incidental harassment authorizations

The National Oceanic and Atmospheric Administrations fisheries category issued long-awaited incidental harassment authorizations to five geophysical contractors to conduct the first oil and gas seismic evaluations on the US Mid-Atlantic Outer Continental Shelf since the 1980s. Oil and gas associations welcomed the agencys Nov. 30 move while environmental organizations strongly criticized it.

No, the worst-case climate change futures havent been ruled out

A single study has been hailed for narrowing the anger of possible climate change scenarios, but figuring out how the world will warm is more complicated than headlines suggest

Climate change is becoming a talking point for 2020 democrats, but theres a Republican in Congress making sure his party gets into the conversation, too. CBSN political reporter Caitlin Huey-Burns and CBSN associate producer Tyler Kendall join CBSN to discuss their article out Wednesday.
