What will we do for Carbon , for life and plant growth?

[AlbertaFarmer5]

So you are admitting that the requirement for scientific evidence is a double standard that only applies to anyone but you? You can make outrageous ficticious claims about CO2 with no sources at all?

Maybe you are right, and the CO2 we have released already will last for 1000's of years, and my concerns about levels declining back to pre-inustrials are unfounded. But until you provide the source for your claim, we don't know.

Humans will be releasing stored carbon into the atmosphere for hundreds if not thousands of years. The carbon cycle will continue. And all that excess carbon released from the burning of millions of years of stored carbon in fossil fuels won’t just disappear in 5 years!

So now you claim we have enough recoverable fossil fuels to last for hundreds if not thousands of years. Do you have a source for that? That is very reassuring if it is true.

So you have now narrowed down the residence time to somewhere between 5 years and thousands of years(but still no source). Do you think that estimated range is accurate enough to justify the actions being proposed? I I would have thought we would have a more precise value for CO2 residence time by now, considering how long the science has been settled already.
Do you think the mitigation efforts and the urgency are on the same scale if the answer is 5 years, vs if it is 1000's of times longer than that?

Fossil fuels are not the only source of stored carbon and other greenhouse gases will also continue to be released. Agriculture and land use plus other industrial uses will have some impact on stored carbon.

But now that you have given up on the fallacy that the short residency of CO2 is a significant factor in human caused climate change, You can move on to other details that laypersons can’t answer? LOL

Why not just ask a climate scientist or look it up yourself?

For those of you care about the residence time of CO2 like A5 read this: https://www.skepticalscience.com/co2-residence-time.htm https://www.skepticalscience.com/co2-residence-time.htm

“It is true that an individual molecule of CO2 has a short residence time in the atmosphere. However, in most cases when a molecule of CO2 leaves the atmosphere it is simply swapping places with one in the ocean. Thus, the warming potential of CO2 has very little to do with the residence time of CO2.“

A5 you still sticking to your grande illusion? LOL

In your highlighted article it states that the C02 in the atmosphere has the potential to warm the atmosphere for 500 years. That shows me that any changes we make will have little affect for possibly hundreds of years, money would be better spent on adaptation!

We need to do both or risk out of control warming that melts the greenland and antarctiac ice sheets and raises oceans many feet.

I was trying hard not to get distracted by your irrelevant side stories, but you have piqued my curiosity. What are these other sources of stoed Carbon (or do you mean CO2, i'm never sure, as you seem to think the two products are interchangeable?), that we can continue to release? That could solve the original dilemma if you have that answer.

As for questions that a layperson can't answer, I was hoping you knew of an expert scientist who would be able to answer, since you as a layperson can only narrow it down to a range between 5 years and at least 1000 times longer than that. Surely the policy makers must have a more exact answer than that. After all, they are proposing to spend trillions, sacrifice the first world and our standard of living, that must be based on settled science?

We need to do both or risk out of control warming that melts all the ice sheets and raises oceans many feet.

Do you really want to go through this all over again? We just spent 8 pages helping you learn about sea level rise. Please reread that thread before beating that dead horse again.

Also, can you provide a citation for the claim of melting "all" the ice sheets? What credible scientific organization is claiming that as a reasonable possibility?

[chuckChuck]

Let me rephrase that. Melting significant amounts of all the ice sheets. Which Is well underway at relatively modest amounts of warming. Backed up by all the major world class scientific organizations which you think are wrong. LOL

[chuckChuck]

All ice sheets are losing mass, some more than others. You can read about it here :
