Carbon-Measuring NASA Satellite to Take Orbit This Week

Climate

A NASA satellite will take orbit Tuesday to help the agency better understand carbon's role in our changing climate.

With the Orbiting Carbon Observatory-2, scientists can record around 100,000 measurements of carbon dioxide measurements in detail each day around the world.

"Now that humans are acknowledging the environmental effects of our dependence on fossil fuels and other carbon dioxide-emitting activities, our goal is to analyze the sources and sinks of this carbon dioxide and to find better ways to manage it," Gregg Marland, a professor in the Geology Department at Appalachian State University, said in a statement from NASA's Jet Propulsion Laboratory.

More than half of all fossil fuels ever used by humans were consumed in the last 20 years. While Marland says that amount totals "only a few percent of the total yearly atmospheric uptake or loss of carbon dioxide from plant life and geochemical processes on land and in the ocean," it has been enough to tip the scale.

Now, NASA will monitor that consumption to complement various efforts to quantify fossil fuel emissions through the use of statistics on fuel, activity of cars and more to pinpoint emissions on scales as small as an individual building or street.

Those efforts are being funded by NASA and led by Kevin Gurney, an associate professor at Arizona State University's School of Life Sciences.

"This research and OCO-2 together will act like partners in closing the carbon budget, with my data products estimating movements from the bottom up and OCO-2 estimating sources from the top down," Gurney said. "By tackling the problem from both perspectives, we'll stand to achieve an independent, mutually compatible view of the carbon cycle. And the insight gained by combining these top-down and bottom-up approaches might take on special significance in the near future as our policymakers consider options for regulating carbon dioxide across the entire globe."

The coronavirus is certainly scary, but despite the constant reporting on total cases and a climbing death toll, the reality is that the vast majority of people who come down with COVID-19 survive it. Just as the number of cases grows, so does another number: those who have recovered.

In mid-March, the number of patients in the U.S. who had officially recovered from the virus was close to zero. That number is now in the tens of thousands and is climbing every day. But recovering from COVID-19 is more complicated than simply feeling better. Recovery involves biology, epidemiology and a little bit of bureaucracy too.

The future for the world's oceans often looks grim. Fisheries are set to collapse by 2048, according to one study, and 8 million tons of plastic pollute the ocean every year, causing considerable damage to delicate marine ecosystems. Yet a new study in Nature offers an alternative, and more optimistic view on the ocean's future: it asserts that the entire marine environment could be substantially rebuilt by 2050, if humanity is able to step up to the challenge.

Across the country, the novel coronavirus is severely affecting black people at much higher rates than whites, according to data released by several states, as The New York Times reported.

Bread has been a source of basic nutrition for centuries, the holy trinity being wheat, maize and rice. It has also been the reason for a lot of innovation in science and technology, from millstones to microbiological investigations into a family of single-cell fungi called Saccharomyces.

The biodiversity loss caused by the climate crisis will be sudden and swift, and could begin before 2030.
