Soot from massive 2017 fire clouds persisted in stratosphere for months

Soot from massive 2017 fire clouds persisted in stratosphere for months

A sooty cloud generated by a 2017 firestorm provided an ideal opportunity for researchers to test a climate model that simulated the lifetime of that soot in the stratosphere.

New NOAA-led study measures soot from North Dakota  flaring in oil and gas fields

New NOAA-led study measures soot from North Dakota flaring in oil and gas fields

In the lonely reaches of northwestern North Dakota and across the border into Saskatchewan, the vast Bakken oil field hosts extensive activities to extract both crude oil and natural gas. Business is booming—production increased by 30 percent between May 2013 and May 2014. More than a quarter of the total gas produced from the Bakken operations can’t be processed fast enough, though, and the common industry practice is to flare it—burn it off as it is vented to the atmosphere. Jutting 30 feet upward like enormous lit matchsticks, the flares pose a new question for atmospheric scientists: What do the flares put into the air? A new NOAA-led study has produced the first direct measurements of how much black carbon—a major component of airborne particles that are commonly referred to as soot —is emitted by the Bakken flaring operations.

Black carbon larger cause of climate change than previously assessed

Black carbon larger cause of climate change than previously assessed

Soot, known as black carbon to scientists, is the second largest man-made contributor to global warming, and its influence on climate has been greatly underestimated.
