Mitigating Methane?

06/11/2021 4:58 PM

If the U. S. (gummint) is so (compulsed) to throw RECORD amounts of tax-payer-dollars around, why doesn't it try to do something that benefits ALL of us by awarding big cash-prize-incentives for creating the best new ways of capturing, transforming, and/or re-purposing, CH4 to counter-act ''Global Warming'' while there's still time? ...

Why "counter-act" something that increases your funding and enhanses your control? And It's Climate Change now BTW. S.M.

Amen! Preaching to the choir.

We're already burning it as fast as we can....

Sounds like a useless exercise in tail chasing...

There are a number of greenhouse gases: CO2, CH4, N2O, and fluorinated gases. The last 3 are more potent at trapping heat than CO2. But you have to factor in the concentration and lifetime in the atmosphere before they are broken down. Taking these into account, CO2 accounts for 3/4 of the warming while methane accounts for about 1/6.

If we could remove all the greenhouse gases from the atmosphere, all life on earth would be extinguished. CO2 is necessary for plant life, and if not for the greenhouse effect, the average temperature would be far too cold.

"Without this greenhouse effect, the average surface temperature would be 255 degrees kelvin (-18 degrees Celsius or 0 degrees Fahrenheit); a temperature so low that all water on Earth would freeze, the oceans would turn into ice and life, as we know it, would not exist."

You left out the biggie, while it isn't as effective as the others you mentioned, the quantity more than counters that. H2O

You are correct, that's a good point.

Water is the wild card. As vapor, it absorbs infrared as a greenhouse gas, and as clouds or snow cover, it reflects solar radiation back into space, so it's playing on both sides. In addition, its concentration varies from place to place and from time to time, pretty much out of our control.

You missed another one that is even more important!

Nitrogen!

It does by far outweigh all other gases.

I thought that we, as Engineers, were supposed to be educated to be problem-solvers, not problem-perpetrators, or -perpetuators.

Based on the (replys) presented herein, I stand corrected...

It probubly takes an imaginary engineer to solve an imaginary problem. So don't get too excited. S.M.

With some exceptions, most people here on this thread and others having to do with the environment seem to THINK they are engineers.

About all they have are opinions. You know, opinions are NOT facts.

This includes the cherry picking Google "scientists" here who can always find a citation that fits their "facts."

..."(Methane) only makes up 0.00017% (1.7 parts per million by volume) of the atmosphere"...

Cherry picked link...

That's what we google scientists call a trace gas...

..."Researchers are now saying say that, globally at least, the increase in recent years is due to the activities of microbes in wetlands, rice paddies, and the guts of ruminants. “Despite the large increase in natural gas production, there has not been an upward trend in industrial emissions,” says Stefan Schwietzke, of the U.S. National Oceanic and Atmospheric Administration (NOAA) in Boulder, Colo., who is the lead author of one of the new studies.

“Since 2007, atmospheric methane has been rising rapidly,” notes Euan Nisbet of Royal Holloway, University of London. But he says his research shows that the increase is dominated by microbial emissions, particularly from the tropics. "....

Why pick on the sources we need to survive?

Again here mankind is characterized as unnatural....we are characterized as some evil invading force....Man is part of nature....we are a natural source...

How much methane do humans produce each year?

Not to mention the noise pollution,and the incidence of rage-related violence in crowded environments?

8 Billion farts/day times average life span in years of 70=560,000,000,000 farts/Yr.

Times 196 milliliters average is a lot of methane.

We should feel guilty every time we flatulate.

Why not include Beano in the USDA MDR of all foods?

Think of how much you will be helping the environment.

Those that refuse the Beano will be fitted with a government mandated surgically implanted charcoal methane absorber,with IoT tracker.

Can I get $$ for a government study on this?

Things like this keep me awake at night.

I am afraid there may be more people like The Farter from Sparta.

This would explain a lot of the greenhouse gasses.
