The carbon sequestration potential of terrestrial ecosystems | Journal of Soil and Water Conservation

The global technical potential of terrestrial C sequestration is some 333 Pg C (367.1 × 109 tn C) by the end of the twenty-first century, equivalent to atmospheric CO2 drawdown of 156 ppm. This must be considered objectively by policymakers and those at all levels of planning and management.

2020 A factor of two: how the mitigation plans of ‘climate progressive’ nations fall far short of Paris-compliant pathways
https://www.tandfonline.com/doi/full/10.1080/14693062.2020.1728209

Without a belief in the successful deployment of planetary scale negative emissions technologies, double-digit annual mitigation rates are required of developed countries, from 2020, if they are to align their policies with the Paris Agreement’s temperature commitments and principles of equity.

Paris-compliant carbon budgets for developed countries imply full decarbonization of energy by 2035-40, necessitating a scale of change in physical infrastructure reminiscent of the post-Second World War Marshall Plan. This brings issues of values, measures of prosperity and socio-economic inequality to the fore.

The stringency of Paris-compliant pathways severely limits the opportunity for inter-sectoral emissions trading. Consequently aviation, as with all sectors, will need to identify policies to reduce emissions to zero, directly or through the use of zero carbon fuels.

The UK and Swedish governments’ emissions pathways imply a carbon budget of at least a factor of two greater than their fair contribution to delivering on the Paris Agreement’s 1.5-2°C commitment.

Halving emission by 2030 and achieving net zero by 2050 will get us to the 1.5°C ambition" is a dangerous myth, and it is unfortunately spreading all over the place
https://threadreaderapp.com/thread/1308881427992399872.html


in summary we have three actual options for 1.5°C:
1. Reduce CO2 ~50% by 2030, net zero 2050, AND REMOVE ~10-100 GtCO2 BEFORE 2100
2. Reduce CO2 by 80%(!) 2030, reach net zero 2050, and stay at zero
3. Reduce CO2 by 55% 2030, reach net zero 2033(!), and stay at zero

PLEASE NOTE that "Halving emission by 2030 and achieving net zero by 2050, and chill" IS NOT ONE OF THE OPTIONS!

...

companies will have a "science-based" net zero goal, based on the flawed premise that that when a company has reaching net zero they have done enough, when SR15 clearly states that that is not the case! Still need to remove massive amounts of CO2

...

The same issue also applies to countries, e.g. the Swedish climate law, which has a net zero date, but no specific goals related to net negative emissions after reaching net zero. Or the EU, which has set a net zero by 2050 goal, and might want to reduce 55% by 2030 (compared to 1990), but also has nothing on negative emissions after 2050.

...

So in summary: Whenever anyone tells you "halve by 2030 and net zero by 2050, and 1.5°C is all set!" you should just ask them politely

"AND WHAT ABOUT THE ON THE ORDER OF 100–1000 GtCO2 TO BE REMOVED DURING THE 21st CENTURY, DID YOU FORGOT ABOUT THAT

The American West is ablaze with fires fueled by climate change and a century of misguided fire suppression. In California, wildfire has blackened more than three million acres; in Oregon, a once-in-a-generation crisis has forced half a million people to flee their homes. All the while, one of our most valuable firefighting allies has remained overlooked: The beaver.
A new study concludes that, by building dams, forming ponds, and digging canals, beavers irrigate vast stream corridors and create fireproof refuges in which plants and animals can shelter. In some cases, the rodents’ engineering can even stop fire in its tracks.
“It doesn't matter if there’s a wildfire right next door,” says study leader Emily Fairfax, an ecohydrologist at California State University Channel Islands. “Beaver-dammed areas are green and happy and healthy-looking.”

Chris Hedges: The Cost of Resistance - scheerpost.com
https://scheerpost.com/2020/09/22/chris-hedges-the-cost-of-resistance/

Two of the rebels I admire most, Julian Assange, the WikiLeaks publisher, and Roger Hallam, the co-founder of Extinction Rebellion, are in jail in Britain. That should not be surprising. You can measure the effectiveness of resistance by the fury of the response. Julian courageously exposed the lies, deceit, war crimes and corruption of the ruling imperial elites. Roger has helped organized the largest acts of mass civil disobedience in British history, shutting down parts of London for weeks, in a bid to wrest power from a ruling class that has done nothing, and will do nothing, to halt the climate emergency and our death march to mass extinction.

The governing elites, when truly threatened, turn the rule of law into farce. Dissent becomes treason. They use the state mechanisms of control – intelligence agencies, police, courts, black propaganda and a compliant press that acts as their echo chamber, along with the jails and prisons, not only to marginalize and isolate rebels, but to psychologically and physically destroy them. The list of rebels silenced or killed by ruling elites runs in a direct line from Socrates to the Haitian resistance leader Toussaint L’Ouverture, who led the only successful slave revolt in human history and died in a frigid French prison cell of malnutrition and exhaustion, to the imprisonment of the socialist Eugene V. Debs, whose health was also broken in a federal prison. Rebel leaders from the 1960s, including Mumia Abu Jamal, Sundiata Acoli, Kojo Bomani Sababu, Mutulu Shakur and Leonard Peltier, remain, decades later, in U.S. prisons. Muslim activists, including those who led the charity The Holy Land Foundation and Syed Fahad Hashmi, were arrested, often at the request of Israel, after the hysteria following 9/11, and given tawdry show trials. They also remain incarcerated.

Melting Antarctic ice will raise sea level by 2.5 metres – even if Paris climate goals are met, study finds | Environment | The Guardian
https://www.theguardian.com/...ea-level-by-25-metres-even-if-paris-climate-goals-are-met-study-finds

Melting of the Antarctic ice sheet will cause sea level rises of about two and a half metres around the world, even if the goals of the Paris agreement are met, research has shown.

The melting is likely to take place over a long period, beyond the end of this century, but is almost certain to be irreversible, because of the way in which the ice cap is likely to melt, the new model reveals.

Even if temperatures were to fall again after rising by 2C (3.6F), the temperature limit set out in the Paris agreement, the ice would not regrow to its initial state, because of self-reinforcing mechanisms that destabilise the ice,

The hysteresis of the Antarctic Ice Sheet
https://www.nature.com/articles/s41586-020-2727-5

So far, we are lacking a comprehensive stability analysis of the Antarctic Ice Sheet for different amounts of global warming. Here we show that the Antarctic Ice Sheet exhibits a multitude of temperature thresholds beyond which ice loss is irreversible. Consistent with palaeodata2 we find, using the Parallel Ice Sheet Model3,4,5, that at global warming levels around 2 degrees Celsius above pre-industrial levels, West Antarctica is committed to long-term partial collapse owing to the marine ice-sheet instability. Between 6 and 9 degrees of warming above pre-industrial levels, the loss of more than 70 per cent of the present-day ice volume is triggered, mainly caused by the surface elevation feedback. At more than 10 degrees of warming above pre-industrial levels, Antarctica is committed to become virtually ice-free. The ice sheet’s temperature sensitivity is 1.3 metres of sea-level equivalent per degree of warming up to 2 degrees above pre-industrial levels, almost doubling to 2.4 metres per degree of warming between 2 and 6 degrees and increasing to about 10 metres per degree of warming between 6 and 9 degrees.

27% US marketu (trzni kapitalizace) tlaci na US congress pro climate policy action

Net Zero Is The New Business Imperative
https://www.forbes.com/...yexchange/2020/09/23/net-zero-is-the-new-business-imperative/#50db5b9d4fd4

Climate change doesn’t pause for pandemics or economic downturns, as evidenced by the wildfires raging on the West Coast, and hurricanes battering the Southeast. These impacts are pounding our economy so frequently and severely that the Commodity Futures Trading Commission’s most recent report, which involved experts from the financial services, energy and agricultural sectors, warns that climate change could destabilize the U.S. financial system.
...

In fact, the number of net zero pledges has doubled in less than a year, including more than 1,500 companies with a combined revenue of more than $11.4 trillion, per a new analysis by NewClimate Institute and Data-Driven Enviro Lab.
...

That’s why this month’s climate policy statement from the Business Roundtable, whose members account for 27% of total US market capitalization, is a powerful call on Congress to make climate policy a top priority. In addition, the group endorsed a set of principles to guide the development of U.S. climate policy.

Co studie Deloitte opomíjí a v čem se mýlí?
Polemika se studií “Ekonomie změny klimatu. Včetně dopadů na Česko”

Oceňujeme, že se konzultační společnost Deloitte, jako jeden z mála komerčních subjektů v ČR, problematikou změn klimatu dlouhodobě zabývá. Jedním z výstupů těchto aktivit je nejnovější analýza dopadů vyvolaných změnou klimatu pro ČR (Deloitte 2020). Tuto studii vítáme, protože přispívá k odborné debatě o závažných problémech, kterým musíme čelit.
Avšak závěry provedeného modelování dopadů klimatické změny - a to jak ve vydané tiskové zprávě, tak v následně uveřejněné studii - nejsou adekvátně podložené, trpí omezeními použitého přístupu a neměly by být používány k zobecnění, o které se studie pokouší. Pokusíme se v následujících bodech vysvětlit proč.
