Global Warming: "Pseudoscientific Fraud"

[snowcat]

Swedish teen climate activist Greta Thunberg arrived in New York City to chants and cheers Wednesday after a trans-Atlantic trip on a sailboat to attend a global warming conference.

Thunberg, 16, and her crew were escorted into a lower Manhattan marina at about 4 p.m., concluding a two-week crossing from Plymouth, England. Hundreds of activists gathered on a Hudson River promenade to cheer her arrival.
Thunberg waved, was lifted onto a dock, then took her first wobbly steps on dry land.
"All of this is very overwhelming," she said of the reception, looking slightly embarrassed.

The teenager refused to fly because of the carbon cost of plane travel. A 2018 study said that because of cloud and ozone formation, air travel may trap two to four times more heat than that caused by just emissions of carbon dioxide and other greenhouse gases.

The sailing team that's taking climate activist Greta Thunberg from England to the United States aboard a high-tech racing yacht says it will fly two crew across the Atlantic to bring the boat back, but that the carbon emissions from their flights will be compensated for.

Question for JL or other scientists: Is there anything to the idea in this paper that carbon dioxide can be sequestered in meaningful quantities with alkaline minerals like olivine?

Abstract:

The weathering of calcium and magnesium silicates is the main natural mechanism limiting
atmospheric CO2 levels. The weathering process transforms CO2 into bicarbonate, which
washes down to the oceans where it ultimately precipitates as carbonate.

However weathering at its natural pace is unable to keep up with current and prospective
anthropogenic CO2 production. Thus we propose to mitigate excess CO2 by increasing the rate
of weathering: olivine, volcanic ash and similar silicate rocks should be mined, milled, and spread
widely, mainly in the humid tropics where weathering rates are highest.

This may produce important additional benefits, reversing the acidification of soils, rivers and
oceans, and enriching soils with mineral nutrients. Oceans would receive additional fluxes of
orthosilicic acid, a limiting nutrient for marine diatoms: the consequent increase in diatom
phytoproductivity could increase carbon fluxes to deep ocean, or support the production of
biofuels in 'diatom farms'.

Carbon capture and storage (CCS) technology attached to power stations is currently being
pursued as a solution to climate change. However CCS costs are estimated as $50-$100/t CO2,
while there are fears as to the long term security of reservoirs. Using accelerated rock
weathering, by contrast, CO2 could be securely and rapidly sequestered for about €10/t CO2,
while bringing benefits to agriculture and forestry, and restoring ocean alkalinity.

With key countries including India, China, Brazil, Indonesia and Canada rich in exploitable olivine
deposits, international acceptance of CO2 mitigation by accelerated weathering would advance
the prospect of achieving an encompassing climate agreement.

I'd post a pic of crickets, but can't find one. I am pretty sure they are all dead due to climate change.

I was hoping one of the scientist types would respond to this because the technoloigy sounds interesting.

Yeah - that's not exactly my area of expertise.

Interesting idea. I am skeptical that it could be effective in terms of cost and scale, but certainly worth a look.

Map of tropospheric NO2 content (an indicator for air pollution) for the month of September 2019 based on data from ESA's Sentinel5-precursor satellite's Tropomi spectrograph... If we got rid of parts of California, New England, and parts of Illinois then the US wouldn't look too bad.

What's causing the indicator for air pollution in Southern Africa?

Keystone ski resort announces this morning that, with the recent snowstorm and upgrades to its snow equipment, it will open tomorrow morning, making it the first resort in the nation to open this ski season. Or so it seemed at the time.

Arapahoe Basin responds with a post at 1:45 pm announcing its grand opening on . . . well, today, at 3:30 pm, getting in about two hours of skiing before Keystone's opening tomorrow.

So delightfully petty. I love it.

Happy ski season everyone.

Wow, early October is amazingly early. Jackson Hole won't open until November 28. The local hill here is saying they'll have good snow for an early season opening but have zero coverage at the moment (it's 50F up there right now).

Thanks for responding. As a follow-up, is it possible that natural carbonate formation has accelerated, and helped delay anthropogenic warming?

As a separate line of questioning, I understand that models are based on simulations. What I don't understand is why the outcome of a warming planet is assuredly negative. It seems that the models would have to yield some probability of positive, or at least less negative outcomes as opposed to the cataclysmic outcomes so widely predicted by those who regularly discuss climate change.

Are you sure those aren't the macqueadores of TJ? (sorry about sp)
