‘Civil Disobedience Has to Become the New Norm.’ Jane Fonda on the Fight Against Climate Change

BY JUSTIN WORLAND UPDATED: SEPTEMBER 3, 2020 4:28 PM EDT | ORIGINALLY PUBLISHED: SEPTEMBER 3, 2020 7:00 AM EDT

Jane Fonda wants to teach you about climate change. In the fall of 2019, Fonda regularly convened with fellow climate activists—and some of her Hollywood friends—on the steps of the U.S. Capitol Building to call for a Green New Deal and other government action on climate change. The protests, which she called “Fire Drill Fridays,” deliberately ended in arrest.

Do you think your book will get older voters to think about climate change and affect the way they vote? 

They’re already thinking about it! The young climate strikers globally have had a lot to do with that. I’m targeting the people who notice the climate crisis and don’t know what to do about it. I’m teaching them more and then giving people things to do… Civil disobedience has to become the new norm. No matter who is elected in November.

Because of climate or everything else going on in the world? 

Because of everything—and out of everything, what looms is the climate crisis. If we don’t cut our fossil fuel emissions in half by 2030, everything will not only become much, much harder, but a lot of things—equality, democracy, stability in our society—will become impossible. What I want to tell voters who say, “I can’t decide who to vote for. I don’t really believe in Joe Biden,” is, “Hey, I’d rather push a moderate than fight a fascist.”

Greens like Fonda completely fail to explain why life would become so much harder so quickly if the world warmed by a few degrees. Every degree of warming is like moving a bit closer to the equator – just not that big a deal.

Fonda is only a useful idiot. It is best to go after the organ grinder, not the dancing monkey. The West is supposed to cut its fossil use by half – which leaves all the oil in the ME to the Chicoms. Who coincidentally will sell us solar panels and wind turbines. Are you getting it (as the late Steve Jobs might say)? Who is benefiting here. Follow the money. The Soviets had the nuclear disarmament and environmental groups well infiltrated. They probably set up the Club of Rome. Now the Chinese have hitched their caboose to the disinformation train, and their booming economy incredibly is using almost half of the world’s resources. They plan to keep on buying SUVs and building condo towers and triple-story wedding-cake mansions and eating lots more meat. Seemingly WE are the only ones who must cut back.

To Dr. Sowell’s point a recent video shows a BLM criminally harrassing a US Congressman by yelling in his face “How do you FEEL about… (police murdering Blacks)”.

It made me extraordinarily uncomfortable that the focus of this useful idiot was on “feelings”.
She would not accept rational answers from her “victim” who agreed any murder is wrong and just kept shouting “how do you FEEL…”

Aside from starting from a false premise, she phrased her shout in the classic “When did you stop beating your wife?” model, where NO satisfactory answer to the accusation exists.

Eric wrote, “Every degree of warming is like moving a bit closer to the equator – just not that big a deal.”

True, and it is easy to quantify what “a bit closer” means, by looking at an agricultural growing zone map. Here’s one, shared by permission from the Arbor Day Foundation:

comment image

From eyeballing the map, it looks to me like 1°C (1.8°F) = about 50-70 miles latitude change.

Here’s James Hansen and his GISS friends reporting a similar figure:

“A warming of 0.5°C… implies typically a poleward shift of isotherms by 50 to 75 km…”

(100 to 175 km = 62 to 93 miles.)
Source: https://pubs.giss.nasa.gov/abs/ha02700w.html

So, the 0.4 to 0.9 °C of warming which we’ve seen since 1958 (when Mauna Loa CO2 measurements began) has caused, on average, a growing zone shift of only about 40 to 135 km (24 – 84 miles).

Ho hum. 🥱

In most places climate changes can be compensated to by farmers, simply by adjusting planting dates.

For example, in Kansas, 0.4 to 0.9 °C of warming can be compensated for by planting 2 to 6 days earlier in springtime:
comment image

In order to find a result in which warmer temperatures cause significant crop damage, you either have to use wildly unrealistic tests (like the Jasper Ridge wild grass study, which used heat lamps outputting 20 times the IR radiation that would be caused by a doubling of CO2), or else assume that farmers are too stupid to adjust their planting dates (like PNAS’s Zhao C, et al. 2017 did). The claim that temperature increases from manmade global warming are significantly damaging to agriculture is crackpot nonsense.

That’s important to know, because the most important effects of climate, weather & CO2 are on agriculture.

At high latitudes, a slightly longer growing season reduces risk of frost damage to crops, and may enable use of high-yielding, slower-maturing cultivars, in some cases. But that’s minor compared to the large benefits of “CO2 fertilization.”

Fortunately, those effects have been heavily studied. The best place to look for such references is in the agronomy literature (which most so-called “climate scientists” apparently never read).

Here’s what eCO2 does for wheat:
https://www.ncbi.nlm.nih.gov/pubmed/26929390

Here’s what it does for corn:
https://www.tandfonline.com/doi/abs/10.1080/00103624.2018.1448413

eCO2 is especially beneficial for legumes, like beans, peas, and alfalfa, which are grown for their protein content. So eCO2 helps mitigate protein shortages in poor countries. Here’s a paper:
https://www.frontiersin.org/articles/10.3389/fpls.2017.01546/full

Hundreds of studies show that eCO2 is very beneficial for all major crops.

eCO2 also enables plants to use water more efficiently. It does so by increasing carbon uptake relative to transpiration. In other words, when grown with higher CO2 levels, plants need less water to get the carbon they need from CO2 in the atmosphere. That is especially helpful in arid regions, and during droughts. Here’s a paper:
http://www.sciencedirect.com/science/article/pii/S0168192310003163
Excerpt:

“There have been many studies on the interaction of CO2 and water on plant growth. Under elevated CO2, less water is used to produce each unit of dry matter by reducing stomatal conductance.”

That’s one of the reasons that eCO2 has contributed to the sharp decline in famines, especially drought-driven famines, which is documented here:
https://ourworldindata.org/famines

To make the case that eCO2 is net-harmful, you would need to show that it has had measurable harmful effects which exceed the value of those measured benefits. Of course there are many modeling studies which speculate about a wide variety of climate-related calamities in the future. But, in science, measurements trump predictions, and it would be very difficult to make a case, on the basis of actual measurements, that manmade climate change has been net-harmful.

Secondary effects on other things, like sea-level, hurricanes & tornadoes, droughts, etc., are also well measured. None of them have significantly worsened, due to the last six decades of rising CO2 levels.

Sea-level trends have been substantially linear since the 1920s. Here’s the best Pacific measurement record, from NOAA. It’s trend is very typical:

Way back in 1908, Arrhenius predicted that CO2 emissions and rising CO2 levels would be very beneficial, rather than harmful.
Excerpt:

“By the influence of the increasing percentage of carbonic acid in the atmosphere, we may hope to enjoy ages with more equable and better climates, especially as regards the colder regions of the earth, ages when the earth will bring form much more abundant crops than at present, for the benefit of rapidly propagating mankind.”

Dave, the truth is Arrhenius got half of it right. What he couldn’t have known from the sparse data in hand then was CO2 is a by-product of ocean warming driven by the sun.

comment image

In the above image, the CO2 plot (circled #17) peaks in the 1990s, at the same time of peak uptake.

From Asynchronous carbon sink saturation in African and Amazonian tropical forests “Overall, the uptake of carbon into Earth’s intact tropical forests peaked in the 1990s. ”

Nature is finely tuned. The outgassing temperature for CO2 is 25.6°C, which is near the mean ideal temperature for subtropical ‘carbon’ uptake vis photosynthesis, 24.1°C to 27.4°C.

Climate change, rainfall/drought cycles, and CO2 are naturally solar-driven.

Reply to  Bob Weber
September 6, 2020 3:22 pm

Bob, that is incorrect. Arrhenius got it right. The oceans are removing CO2 from the atmosphere, not adding it.

CO2 has not peaked. Annually averaged atmospheric CO2 concentration has risen every year since precise measurements began.

You might have been listening to Dr. Murry Salby, who claims that atmospheric CO2 levels are rising, not because of anthropogenic CO2 emissions, but because global warming is causing the oceans to outgas CO2. It’s not, and they aren’t. He is confused.

As CO2 levels climb, the rate at which nature (mainly oceans & biosphere) removes CO2 from the air increases.

The rate of CO2 absorption by water is controlled mainly by atmospheric CO2 partial pressure, per Henry’s Law. It’s a bit more complicated than that, but not much. The CO2 levels in ocean and air are far from equilibrium. The atmospheric CO2 partial pressure has increased by nearly 50%, and the dissolved CO2 concentration in the ocean has increased only slightly. The ocean’s carbon storage reservoir is vast, compared to the atmosphere, and calcifying coccolithophores transport carbonates from surface water, where the CO2 dissolves, to the ocean depths. So return of that carbon to the atmosphere would take a very, very long time, and some of it will never return.

The terrestrial biosphere’s removal of CO2 from the atmosphere is more complicated, but that rate also increases as CO2 levels rise:
comment image

The difference between the amount of anthropogenic CO2 emitted, and the amount by which CO2 level increases year-to-year, is the “CO2 removal rate.” That’s the rate at which negative feedback mechanisms, like terrestrial “greening” and dissolution into the oceans, remove CO2 from the atmosphere. It has been greater than zero every year since precise atmospheric CO2 level measurements began.

The CO2 removal rate is affected by many factors, but principally by the atmospheric CO2 level. Dr. Roy Spencer examined it, and found that it is closely approximated by a very simple function:

    (co2level – 295.1) × 0.0233
    (units are ppmv CO2)

Mankind is currently adding about 5 ppmv of CO2 (about 10½ PgC) to the atmosphere each year, but the atmospheric CO2 level is only rising at a rate of about 2.5 ppmv per year. The difference is the rate at which natural negative feedbacks (mainly terrestrial greening and absorption by the oceans) remove CO2 from the air: currently about 2.5 ppmv per year.

When Salby claims that nature is raising the atmospheric CO2 level, it makes me wonder how he can be incapable of subtracting 2.5 from 5.

The solubility of gases like CO2 (or CH4) in water does decrease as the water gets warmer (per the temperature dependence of Henry’s law), so as the oceans warm they would outgas CO2, if nothing else changed. The capacity of the water to hold dissolved CO2 decreases by about 3% per 1°C by which the water warms.

The measly 3% per °C, by which CO2 solubility in water decreases as the water warms, is dwarfed by the 48% by which solubility increased as atmospheric CO2 concentration rose by 48% (from 280 ppmv to 414 ppmv). As the atmospheric CO2 level continues to rise, the rate at which the oceans remove CO2 from the air will continue to accelerate.

So, when the oceans are absorbing CO2, as is currently the case in most places other than the tropics, if the water warms then the oceans absorb CO2 just a little more slowly.

The CO2, in turn, works as a GHG to cause warming, which is one of the reasons that atmospheric CO2 levels swing up & down by about 90 ppmv over glaciation/deglaciation cycles. (There are almost certainly also biological [2] and/or ice sheet burial mechanisms at work, which increase the magnitude of glacial-interglacial CO2 swings.) That’s a slight positive feedback mechanism.

That positive feedback loop is undoubtedly one of the causes for the apparent hysteresis [2] in the temperature and CO2 records: Over the last million years, the Earth’s climate has tended to be either mild, as in our current interglacial (the Holocene), or, more of the time, heavily glaciated and cold, with relatively brief, unstable transitions between. (But see also: Deglaciation / Volcanism / CO2 Feedback.)

In paleoclimate reconstructions from ice cores, CO2 level changes generally lag temperature changes by hundreds of years, which is consistent with the fact that higher CO2 levels not only cause higher temperatures, but are also caused by higher ocean temperatures, and ocean temperature is slow to respond to air temperature changes.

BTW, you don’t need Henry’s Law to understand, intuitively, why the rate at which the ocean absorbs CO2 from the air increases with CO2’s partial pressure in the air. Just remember that the concentration of CO2 in the air determines the rate at which CO2 molecules collide with and are absorbed by the surface of the ocean, and falling raindrops.

For a more complete treatment of this issue, I strongly recommend this essay by Ferdinand Engelbeen:

Bob Weber wrote, “…adjusted for the trend, 1997 was the peak year for CO2.”

Translation: “If you ignore the increase in CO2 level, 1997 was the peak year for CO2 level.” Or something like that.

Perhaps you’re trying to say that the rate of increase in CO2 level peaked in 1997? That would be irrelevant, even if it were true, but it’s not true, anyhow. Note the slight upward-curve in this plot of annually-averaged CO2 concentrations; concave-upward means accelerating:
https://www.sealevel.info/co2.html

There was a spike in the rate of CO2 increase in 1998 (not 1997), due to the El Niño. 1998’s average CO2 level at Mauna Loa was 2.97 ppmv higher than 1997’s. Maybe that’s what you’re talking about?

But so what? That’s what happens during El Niños. The 2016 El Niño was accompanied by an even larger 3.41 ppmv CO2 level increase.

In 1997, the average CO2 level for the year increased by 1.12 ppmv over 1996’s average level, at Mauna Loa.
In 1998, the average CO2 level increased again, this time by 2.97 ppmv over 1997.
In 1999, the average CO2 level increased again, this time by 1.58 ppmv over 1998.
In 2000, the average CO2 level increased again, this time by 1.17 ppmv over 1999.
Etc.

The annually-averaged atmospheric CO2 concentration has continued to increase, every year since 1958, when precise measurements began at Mauna Loa. More recently:

In 2018, the average CO2 level increased again, to 408.52 ppmv, which was an increase of 1.97 ppmv over 2017.
In 2019, the average CO2 level increased again, by 2.92 ppmv ppmv over 2018.

Because CO2’s warming effect is logarithmically diminishing, the climate forcing trend from rising CO2 level has been close to linear for the last forty years or so, as you can see in this log-scale plot:
https://www.sealevel.info/co2.html?co2scale=2
 

Bob previously asked, “…I do my own work. If there’s a similarity to Salby maybe you can tell me what it is.”

You both think that when mankind adds CO2 to the atmosphere it doesn’t increase the amount of CO2 in the atmosphere. Or something like that. 🤔
 

Bob also boasted, “I know outgassing better than you or Ferdinand.”

You have my sympathy. I’ve found that switching to lactose-free dairy products helps.

Ocean carbon sink processes not understood and driven by natural variability

McKinley et al. (2017) analyzed ocean carbon sink estimates and was willing to admit that due to a lack of observation, we lack a “detailed, quantitative, and mechanistic understanding of how the ocean carbon sink works…

In addition, because internal variability in oceanic carbon uptake is so massive and largely unobserved, we cannot yet detect an anthropogenic influence.

McKinley and co-authors go so far as to acknowledge the “change in CO2 flux over 10 years (1995-2005)…is due almost entirely to the internal variability” because in most ocean regions “the forced [human-induced] trends in CO2 flux are too small to be statistically significant” and the “variability in CO2 flux is large and sufficient to prevent detection of anthropogenic trends in ocean carbon uptake on decadal timescales.”

You have a major gaslighting problem Dave Burton, aside from your inability to so science.

Thank you, Bob for at least admitting that the ocean IS a carbon sink, rather than a net source of atmospheric CO2. I’ll take that as your acknowledgment that “The oceans are removing CO2 from the atmosphere, not adding it,” and that, therefore, the ongoing rise in atmospheric CO2 levels is not due to outgassing from the oceans.

Thanks, too, for the link and quotes from McKinley et al.

I wonder, though, why you didn’t quote the very first sentence of the McKinley’s abstract, since it directly addresses this topic:

Since preindustrial times, the ocean has removed from the atmosphere 41% of the carbon emitted by human industrial activities.

That’s number is actually too high.

Estimated industrial CO2 emissions (1751-2019) were about 452.3 PgC = 206 ppmv
source: https://cdiac.ess-dive.lbl.gov/ftp/ndp030/global.1751_2014.ems
spreadsheet: https://sealevel.info/global.1751_2014.ems5.html#:~:text=Sum%201751-2019

But over that time period atmospheric CO2 concentration rose only about 412 – 277 = 135 ppmv. That means nature removed about 206-135 = 71 ppmv, which is 34.5% of anthropogenic emissions.

We also know that some of that carbon went into the biosphere and soil, rather than the oceans. If the oceans removed half of that, and the biosphere removed the other half, that would mean the oceans removed only about 17% of industrial CO2 emissions, not 41%.

Oh, well. At least they got the sign right, which puts them ahead of Dr. Salby.

Correction: “175 km” should have been “150 km”.

I remember citrus groves in north Florida in the 50’s. And I don’t notice it being appreciably warmer today. However it was cold enough during the 70’s and 80’s to regularly kill citrus. Funny thing about climate. It changes.

Jane has it backwards. If she and her fellow travellers don’t stop demanding the end of fossil fuel use, democracy will become increasingly impossible by 2030, so it looks like we’ll get ten more years of their whining to look forward to since their real goal is the elimination of our freedom, democracy and republican form of government.

She’s still alive?

WOW.

Guess that’s all this was–a publicity stunt to say, “Hey, I’m still breathing over here!”.

She pops up whenever she thinks the public has forgotten about her……it’s nothing more than that. She normally has nothing of substance to say–and gets arrested. I think her goal is to be arrested more times than any “activist” (in quotes for a reason….people that really don’t believe what they are shilling but want the press for it).

So if half is cut by Dec 31, 2029, OK, but if not until Jan 2, 2030, democracy dissolves. Notice that Jane does not even begin to provide any logical reasons for her bizarre prediction. N one will be able to notice any changes between now and 2030, so why will anything as ridiculous as “democracy dissolution” occur?
