    Soil Grown Tall: The Epic Saga of Life from Earth | SpringerLink
    https://link.springer.com/book/10.1007/978-3-030-88739-1

    "Soil Grown Tall" looks at the role of life in buffering the global carbon cycle, using evidence captured in paleosoils - fossil soils - over periods stretching back right to the beginning of the solar system..

    Gregory is a pretty rare creature - a geologist and paelobiologist specialised in paleosoils, which he has analysed and studied way more than anyone else. He's always expressed surprise at how few colleagues made paleosoils their life's calling and, reading this masterpiece, you cannot but agree with him. More knowledge about our planet's history is hidden in fossil soils than anywhere else.

    Retallack shows how paleosoils contain plenty of evidence towards what he calls the Proserpina Principle, or the way the planet achieved homeostasis - long-term stability - without falling either into a runaway greenhouse, like Venus, or an unchanging snowball, like Mars. The secret? A never-ending evolutionary arms race between producers (plants) and consumers (animals).

    For example, when trees evolved they precipitated a serious ice age, as lignin is so, so hard to digest. When termites evolved the ability to digest wood a hundred million years later or so, they tipped the planet into a greenhouse world, as they put all the carbon trees had captured back in the air.

    Similar producer-precipitated ice ages came earlier (with the evolution of lichens) and later (with the evolution of grasses), interrupted by consumer-precipated greenhouse worlds.

    That dance goes back to the very dawn of life: the microbial mats that covered the world three thousand million years ago also drew down vast amounts of carbon dioxide, both directly through photosynthesis, and by enhancing weathering through the acids they produced. They, as much as lichens and trees, were responsible for planetary deep freezes.

    The Proserpina Principle kept the planet liveable through mile-wide asteroid impacts and continent-sized volcanic eruptions (see the Siberian or Deccan traps). The huge amounts of carbon that spewed into the air heated the world up, which encouraged plant growth even into polar regions, which soon drew that carbon back into seas and soils.

    What this long view leaves you with is, first, that as far as the planet is concerned, we're just the latest consumers tipping the world into a greenhouse (two hundred million years before termites, millipedes did a great job too), and second, that whether we fine-tune the system to keep Holocene-like stability (through all our favourite nature-based solutions, from agroforestry and holistic grazing to ocean iron fertilization and kelp forests) or not, matters little to the world: a hotter one will see less ice and deserts and more forests and grasslands, and they'll do the job of getting carbon back out of the atmosphere whether we like it or not.

    Of course, something that matters little to the world may still matter a lot to us. Sea levels 90m higher and crocodile-infested rainforests in Antarctica may be business as usual for the planet, but most definitely not for us.

    New Energy Infrastructure Chief Wants Companies To Feel FOMO Over Decarbonization
    https://www.forbes.com/sites/jeffmcmahon/2023/06/28/new-energy-infrastructure-chief-wants-companies-to-feel-fomo-over-decarbonization/

    We need to create an air of inevitability that these things are going to happen so that everyone's moving in the same direction,” said David Crane on June 14, less than an hour after being sworn in as undersecretary.
    ...
    What we're trying to do with the $6.3 billion for industrial decarb is to bring that 2035 date for deep decarbonization of processed heat into this decade,” he said, “and so if you still have a plan to do that in the 2030s you're going to be left behind.”
    ...
    Crane was CEO of Houston-based NRG Energy for 12 years. He also served as director of DOE’s Office of Clean Energy Demonstrations. Prior to government service, he was the CEO of Climate Real Impact Solutions and served on the Boards of Heliogen Inc, Source Global, JERA Co. Inc., and Tata Steel Ltd, along with the not-for-profit Boards of Elemental Excelerator and The Climate Group NA. He was confirmed as undersecretary June 8 by a Senate vote of 56 to 43.

    Experience exceeds awareness of anthropogenic climate change in Greenland | Nature Climate Change
    https://www.nature.com/articles/s41558-023-01701-9

    Greenlanders are more likely than residents of top oil-producing Arctic countries to perceive that climate change is happening and about twice as likely to have personally experienced its effects. However, half are unaware that climate change is human-caused and those who are most affected appear to be least aware

    Vesta calculates that the North Sea Beach project will remove roughly 400 tonnes of CO2 from the atmosphere, after factoring in emissions from mining, grinding and shipping the olivine from Norway. The company plans to sell carbon credits, but the US$2-million pilot project will neither make money nor alter the climate, says Andrews. “It is a proof of concept.”

    První rána Green Dealu. Europoslanci ze "zeleného" výboru odmítli klíčovou normu - Aktuálně.cz
    https://zpravy.aktualne.cz/zahranici/evropsky-parlament/prvni-rana-green-dealu-europoslanci-ze-zeleneho-vyboru-odmit/r~7f26272e14f111eea25a0cc47ab5f122/?

    Verdikt výboru pro životní prostředí řadu politiků zaskočil, protože jeho členové jsou víc ekologicky smýšlející než zbytek sedmisethlavého parlamentu. Předpokládalo se tudíž, že návrh projde. Norma ukládá, aby se část nyní obdělávané nebo zastavěné půdy vrátila původnímu užití, tedy volné krajině. EU se tím snaží zabránit úbytku populace rostlin a živočichů na kontinentu.
    ..
    Návrh označil "za špatnou dohodu pro Evropany", kterým by podle něj hrozil až nedostatek potravin kvůli omezení využívané zemědělské půdy. Zastánci obnovy přírody to označují za lži a strašení lidí.

    https://www.researchgate.net/publication/366136487_Global_warming_in_the_pipeline

    Improved knowledge of glacial-to-interglacial global temperature change implies that fast-feedback equilibrium climate sensitivity is at least ~4°C for doubled CO2 (2xCO2), with likely range 3.5-5.5°C. Greenhouse gas (GHG) climate forcing is 4.1 W/m2 larger in 2021 than in 1750, equivalent to 2xCO2 forcing. Global warming in the pipeline is greater than prior estimates. Eventual global warming due to today's GHG forcing alone -- after slow feedbacks operate -- is about 10°C. Human-made aerosols are a major climate forcing, mainly via their effect on clouds. We infer from paleoclimate data that aerosol cooling offset GHG warming for several millennia as civilization developed. A hinge-point in global warming occurred in 1970 as increased GHG warming outpaced aerosol cooling, leading to global warming of 0.18°C per decade. Aerosol cooling is larger than estimated in the current IPCC report, but it has declined since 2010 because of aerosol reductions in China and shipping. Without unprecedented global actions to reduce GHG growth, 2010 could be another hinge point, with global warming in following decades 50-100% greater than in the prior 40 years. The enormity of consequences of warming in the pipeline demands a new approach addressing legacy and future emissions. The essential requirement to "save" young people and future generations is return to Holocene-level global temperature. Three urgently required actions are: 1) a global increasing price on GHG emissions, 2) purposeful intervention to rapidly phase down present massive geoengineering of Earth's climate, and 3) renewed East-West cooperation in a way that accommodates developing world needs.

    Global Warming in the Pipeline
    https://youtu.be/v-ArA_xYxfs


    Dr. Peter Carter, Paul Beckwith and Regina Valdez discuss a recent paper called ‘Global Warming in the Pipeline’ by James Hansen et al. The paper explains global warming will likely pierce the 1.5°C ceiling in the 2020s and 2°C before 2050 under the current geopolitical approach to dealing with anthropogenic greenhouse gas emissions.

    This video was recorded on May 24th, 2023, and published on June 18th, 2023.

    Some of the topics discussed:
    - How one of the key characteristics of climate change known for decades has always been inertia and momentum. This paper shows that at the current levels of greenhouse gases in the atmosphere, the planet is slowly moving towards a 10°C rise in global average temperature.
    - How James Hansen is a voice crying in the climate wilderness as he always seems to have been because the scientific community is not agreeing with him.
    - How one of the big feedbacks in the climate system is ice sheet albedo and its key role in leading us to a 10°C rise.
    - How the methane emissions feedback from the warming of the wetlands will be inevitable.
    - How a new draft of the paper was released on May 19th.
    - How the Global Climate Models (GCMs) have been under predicting the global average temperature rates of change and how by using the Equilibrium Climate Sensitivity (ECS), which is how much the climate warms for a doubling of CO2 levels, we can arrive at much more accurate prediction of global average temperature rise from paleoclimate data.
    - The enormity of consequences of climate change demands a return to a Holocene-level global temperature with the required actions that include: 1) A global increasing price on GHG emissions; 2) An East-West cooperation in a way that accommodates developing world needs; 3) Intervention with Earth’s radiation imbalance to phase down today’s massive human-made “geo-transformation” of Earth’s climate.
    - and much more. . .

    ESSD - Indicators of Global Climate Change 2022: annual update of large-scale indicators of the state of the climate system and human influence
    https://essd.copernicus.org/articles/15/2295/2023/

    The indicators show that human-induced warming reached 1.14 [0.9 to 1.4] ∘C averaged over the 2013–2022 decade and 1.26 [1.0 to 1.6] ∘C in 2022. Over the 2013–2022 period, human-induced warming has been increasing at an unprecedented rate of over 0.2 ∘C per decade. This high rate of warming is caused by a combination of greenhouse gas emissions being at an all-time high of 54 ± 5.3 GtCO2e over the last decade, as well as reductions in the strength of aerosol cooling. Despite this, there is evidence that increases in greenhouse gas emissions have slowed, and depending on societal choices, a continued series of these annual updates over the critical 2020s decade could track a change of direction for human influence on climate.
