A Pathway To 350 PPM Part 1: Carbon Sequestration Is Vital | CleanTechnica

According to a paper by Hansen et al., a safe level of atmospheric CO2 to avert runaway global warming is below 350 PPM. Before our discovery and use of fossil carbon, pre-industrial CO2 levels hovered around 280 PPM. So we have our work seriously cut out for us not only to reduce our emissions, but remove (sequester) GHGs from the atmosphere.

Carbon Sequestration is vital for overcoming the climate crisis
In order to quickly return atmospheric greenhouse gases to safe levels and avoid triggering positive feedback loops, not only do we need to stop burning fossil carbon, we need to implement carbon sequestration strategies

There are two types of carbon sequestration: Geological Carbon Capture and Storage (GEO-CCS) and Biological Carbon Capture and Storage (BIO-CCS) also known as carbon farming. GEO-CCS uses technology, including sorbents, electricity, and heat, to capture and store the whole CO2 molecule ultimately underground. BIO-CCS relies on the natural photosynthesis of plants to separate the oxygen atoms of CO2 and store the carbon atoms in the stem and roots of plants. Some BIO-CCS examples include forestry, timber and biomass plantations, and ecosystem protection and restoration.

Out of the investor thread from a few days ago:

The main solution for agriculture is to electrify the agricultural equipment (tractors etc.)

There's other things you can do beyond that. Moving back to renewable fertilizers instead of fossil fuel-derived ones helps. For livestock, collecting methane from manure (instead of letting it escape to atmosphere can help). Controlling feed and/or gut bacteria to minimize animal methane emissions (especially in ruminants) helps, and there's research being done to figure out how to best do this.

Probably the best thing is to have an agricultural system that was not monoculture. The flooding and loss of topsoil this spring would have been far less if only a section of the farmland was waiting to be replanted rather than all of it.

For livestock, collecting methane from manure (instead of letting it escape to atmosphere can help).

Problem with that is it's likely only practical under the worst, tightly packed, industrial farming scenarios.

Which is mostly where we get our meat, amirite? Driving through western Kansas seems to show that.

 

[JRP3]

We should probably change that for many reasons.

I concur.

adsorb

He doesn't even know the difference between "absorb" and "adsorb". Wow.

 

[nwdiver]

So what you just posted concludes that, because trees (and plants) may be able to adsorb co2 and mitigate your "climate change" they could derail your CAGW agenda. Correct?

Correct. We just need to plant >1B square miles of trees on a planet with ~200M square miles of land. By your 'logic' that will totally work

 

[ggr]

Pointing out bias is not ad hominem. Calling someone a denier is.

Ohmman's reply was to @Swampgator calling my reply for saying I pointed out bias. But I didn't do that. I pointed out internal inconsistency in @Swampgator's statements. That is simple fact, not bias. And I didn't call @Swampgator or anyone else a denier. Is denying denial denial?

 

[ggr]

He may mean "corroborated."

No collusion!

 

[Swampgator]

Because you folks are training the AI and perhaps he doesn’t have access to a dictionary?

Yeah, you guys got me on a typo. Great work team alarmist!

 

[Swampgator]

So you agree that CO2 causes climate change? If only there was an energy source that didn't emit CO2.... oh, wait...

For the ~13th time.... if it's not the ~40% rise in CO2... WHAT IS IT???????????????

And for the 10th time, temperature changes happen ALL THE FREAKING TIME in the earths history. Mostly completely independent from CO2 changes. Get that through your skull.
I have showed you times when CO2 was high and yet we went into ice ages. I can show you times when CO2 was low and yet the earth warmed. I know the CO2 hypothesis fits nicely into your human hating worldview, but no explanation is needed to explain temperature changes that fall inside the range of normal natural variability.

Has Your Doctor Talked To You About Climate Change?

When Michael Howard arrives for a checkup with his lung specialist, he's worried about how his body will cope with the heat and humidity of a Boston summer.

In June, the American Medical Association, American Academy of Pediatrics and American Heart Association were among 70 medical and public health groups that issued a call to action asking the U.S. government, business and leaders to recognize climate change as a health emergency.

"The overall trend of the hotter summers that we're seeing [is] due to climate change," Rice says, "and with the overall upward trend, we've got the consequences of climate change."

How did you fare during hurricane Andrew back in 1992? It was teeny tiny compared to hurricane Irma in 2017, don’t forget Jeanie or the other 2 that year, hurricane Charlie that nailedwestern Florida south of Sarasota, oh and hurricane Maria right after Irma what scraped Puerto Rico that 2 years later still has electricity problems, hurricane Michael that devastated the Florida panhandle, there’s a (was no longer) town that was called Mexico Beach, pretty much gone, don’t forget hurricane Harvey, 9 Trillion gallons dumped on Houston, hurricane Gilbert that completely filled the entire Caribbean, random Derecho (inland hurricane) that hit Washington DC a few years ago “and Snowpocalypse and Snowmageddon the next year that dumped huge amounts of water(snow), a rainstorm that dumped record amounts of water on Washington DC in an _afternoon_ last week. Superstorm Sandy, 1,100 miles wide, a hurricane 1,100 miles wide.
All heat engines, running on excess heat (energy) dumped in our collective atomosphere
And typhoon Hyune with a 30 mile wide well defined central eye.
Deny AGW all you want, call us “believers” or “liberals” whom are actual scientists, know a lot of other reputable scientists who publish peer reviewed articles in journals, but meanwhile, pack your valuables and skeddadle to higher ground, although Delaware is only 70ft above msl so not there
I would suggest you read a few articles from say, “journal of the Holocene” where Michael Mann published a few seminal articles, although you might have to go to a college that subscribes so you can read for free.
Meanwhile, you are taking up space just to take up space it seems from the noise to signal ratio
Have a “blessed” day

As a physician yourself, you should be embarrassed to post that.
Seriously. How is the dude going to cope with the hot, humid, Boston summer? Give me a break. I live in SW Florida. Try coming down here pal. Somehow, we all survive the long hot summers down here. Feel for that Boston guy though.

Rather long winded post yourself my friend. Irma came directly over my house. We did great, although we did lose power for a few days. ANd I'll pass on reading anything form Michael Mann, thank you. Mr Hockey stick is an activist posing as a scientist.

Go back to your Heartland bosses and tell them they need to update the agenda, this bogus claim has already been debunked!

Natural variability can not explain modern global warming, as Heartland Institute report claims

Or if you want to look at longer range since last ice age:
This Stunning Graphic Shows Earth’s Temperature Over 22,000 Years

Notice 2 important things on that long graph:
1. Natural warming since last ice age peaked at about 5000BC, then temperature started to cool, but that cooling trend got suddenly reversed since the industrial revolution
2. The rate of temperature change in the "natural" ice age cycle was much slower (several orders of magnitude) than the rate of warming in the last ~100 years.

I have nothing to do with Heartland so that's a fail. And that debunking is simply the opinions of a few, pro CAGW scientists. I can find other scientists who disagree. So what? The hard facts are it has been warmer than today, in the past. CO2 has been higher than today's levels. The earth is 4 billions years old and has had MANY temperature swings. Large ones that wiped out entire Orders if not phylums. Do you disagree with that?

Yes, there were major temperature swings and climate changes in the history of earth. There are two problems with bringing that up as an argument:

1. Those natural changes were 100-1000 times SLOWER than the current one caused by humans.
2. Even those slower changes resulted in mass extinction of 90%+ of species including all of those at and near the top of the food chain.

Evolution can react to changes at a certain speed dictated by the life-cycle of the species. Bacteria have life cycles measured in hours, humans and large mammals have life cycles measured in decades. So, some bacteria species may have a chance to survive the extinction level event we are causing, but not humans or any species big enough to see with the naked eye.
