Study on formaldehyde scavenging in thunderstorms shows changing ideas about atmospheric processes

Study on formaldehyde scavenging in thunderstorms shows changing ideas about atmospheric processes

Thunderstorms are powerful things: their churning circulation can stir gases from the lower atmosphere into the upper atmosphere and even the lower stratosphere. They can also scrub gases out of the air by dissolving them in raindrops, a process known as scavenging. In a new study, INSTAAR scientists in collaboration with other scientists at CU and NCAR found that scavenging is not nearly as effective as previously believed for some soluble and highly reactive trace gases, a result that may change our views of atmospheric chemistry in a warming climate.

Water and natural gas: Win some, lose less?

Natural gas has been touted as a “bridge fuel” which would allow us to transition towards cleaner alternatives in the future while leaning away from emission-heavy carbon based fuels. We looked at some of the atmospheric consequences for using natural gas last week, and this week we’re taking a closer look at water. Water lost to fracking may be mitigated by water savings during power generation.
