Ninth sandstorm in less than two months shuts down much of Iraq | Iraq | The Guardian

Iraq is ranked as one of the world’s five most vulnerable nations to climate change and desertification.

The environment ministry has warned that over the next two decades Iraq could endure an average of 272 days of sandstorms a year, rising to above 300 by 2050.

Iraq’s previous two sandstorms sent nearly 10,000 people to hospital with respiratory problems and killed one person.

It’s publication day! In researching Regenesis, I found hope where hope seemed absent. I stumbled across astonishing stories and unimagined possibilities. I pieced together what I see as a plausible future for humanity and the wonderful life with which we share this planet.

My message to graduates as they embark on their professional careers:

Don’t work for climate-wreckers.

Use your talents to drive us towards a renewable future.

We all have a responsibility not to squander our skills, but to use them in a responsible and constructive way.

nejaky relativne dobry zpravy. rychly prirustek biomassy po pozarech v australii. chapu-li to spravne, tak uvilnenej uhlik uz by mel byt zpatky v biomase?

Here, we analyzed space-borne optical, thermal, and microwave images to assess changes in the structure and function of vegetation using four vegetation indices (VIs), leaf area index (LAI), solar-induced chlorophyll fluorescence (SIF), gross primary production (GPP), and aboveground biomass (AGB). We found that all eight variables show large losses in 2019, driven by fires and climate (drought and high temperature), but large gains in 2020, resulting from the high resilience of most trees to fire and rapid growth of understory vegetation under wet condition in 2020. In 2019, the forest area has an AGB loss of 0.20 Pg C, which is ~15% of the pre-fire AGB. Attribution analyses showed that both fire and climate (prior and co-occurring severe drought and record high temperatures) are responsible for the AGB loss in 2019, approximately 0.09 Pg C (fire) and 0.11 Pg C (climate), respectively. In 2020, the forest area has a total AGB gain of 0.26 Pg C, composed of 0.22 Pg C from fire-affected forest area and 0.04 Pg C from fire-unaffected forest area. Fire-adapted Eucalyptus forests and above-average annual precipitation in 2020 brought by a moderate La Niña drove the recovery of vegetation cover, productivity, and AGB.

Farmers in England are starting to bury a charcoal-like material in their fields to see if it could offer a new large-scale way of putting the brakes on climate change.
Biochar is the carbon-rich material left over from burning wood and other biomass at high temperatures in an oxygen-free environment. Most of its use today is at the small scale, such as gardeners using it as a fertiliser.

Uhlikovou dan na vytezene = Uhlikovou dan na vytezenou ropu/uhli/plyn, ...

Tzn. obecne.

Uhlikovou dan na vytezene

1. Plasty
- snizit druhovou rozmanitost
- primarni recyklace tam kde to jde
- preferovat PET (a jeho modernejsi derivaty) pro potravinarstvi kvuli moznosti uplne recyklace (tj. ne downcykl) (plus ultimatni parametry PETu, stabilita, netoxicita, nic se z neho neuvolnuje, etc.).
- Zbytek nevyuzitelnych plastu a dalsi ropnych odpadu pyrolyzne, nebo plasmovym zplynovanim na syngas.

Syngas → pro prechodne obdobi synteticky methan, synteticka paliva.* (Postupny prechod na H2 a namist paliv bateriova akumulace). Pozdeji nahrada esencialnich ropnych produktu (zejmena rozpoustedla a mazadla)

* [PETER_PAN @ Klimaticka zmena // Jak sesekat emise? Novy IPCC report je venku. Kdo posle nejlepsi vytah dostane diplom]

2. Komunalni odpad po vytrizeni. Vsechno na Syngas.

3. Dlouhodobe carbon capture. CO2 vyuzit pro vyrobu materialu (preferovat materialy s dlouhodobou fixaci uhliku).

DZODZO: Ne. Materialy.

Pod pojmem "Olefines" si muzes predstavit monomery pro polymerni chemii. Od tech co maji malou zivotnost a jsou biologicky rozlozitelne (LD-PE) az po stabilni PB-1. Olefiny se daji transofrmovat i na aromaticke slouceniny a z nich delat plast s zivotnosti radove stovky let. Olefiny se daji take vhodne oxidovat, da se udelat i strojni polyamid (s prispenim dalsich latek samozrejmne).

Dlouha zivotnost vypada jako negativum, ale je to naopak zadouci. Snizit neabrazivni formaci mikroplastu, dlouhou zivotnost s dlouhu fixaci uhliku. Zaroven ponechat dobre vlastnosti pro primarni recyklaci (u rychle degradujicich plastu je primarni recyklace vzdycky kompromis). Tohle chceme.
