Trees and Land Absorbed Almost No CO2 Last Year 86

The Earth's natural carbon sinks -- oceans, forests, and soils -- are increasingly struggling to absorb human carbon emissions as global temperatures rise, raising concerns that achieving net-zero targets may become impossible. "In 2023, the hottest year ever recorded, preliminary findings by an international team of researchers show the amount of carbon absorbed by land has temporarily collapsed," reports The Guardian. "The final result was that forest, plants and soil -- as a net category -- absorbed almost no carbon." The Guardian reports: The 2023 breakdown of the land carbon sink could be temporary: without the pressures of drought or wildfires, land would return to absorbing carbon again. But it demonstrates the fragility of these ecosystems, with massive implications for the climate crisis. Reaching net zero is impossible without nature. In the absence of technology that can remove atmospheric carbon on a large scale, the Earth's vast forests, grasslands, peat bogs and oceans are the only option for absorbing human carbon pollution, which reached a record 37.4bn tonnes in 2023.

At least 118 countries are relying on the land to meet national climate targets. But rising temperatures, increased extreme weather and droughts are pushing the ecosystems into uncharted territory. The kind of rapid land sink collapse seen in 2023 has not been factored into most climate models. If it continues, it raises the prospect of rapid global heating beyond what those models have predicted.
"We're seeing cracks in the resilience of the Earth's systems. We're seeing massive cracks on land -- terrestrial ecosystems are losing their carbon store and carbon uptake capacity, but the oceans are also showing signs of instability," Johan Rockstrom, director of the Potsdam Institute for Climate Impact Research, told an event at New York Climate Week in September.

"Nature has so far balanced our abuse. This is coming to an end."

That way, if ThingX has any negative effects on humans or the environment, they have ample time to mount a disinformation campaign and bribe people at key positions before everyone else is even aware a problem exists, essentially being one lap ahead of everyone else.

    Now that the problem is blowing up in our faces, take note of who's been telling you that this is a problem that needs to be dealt with for decades and who's been lying about even the existence of the problem since the beginning.

      It means there was no net growth.

      Some trees grew. Others rotted or burned.

      2023 was a record year for forest fires.

      • On the bright side, if we can reduce forest fires, we will be getting a net carbon sink from forests again. And recently burned areas should grow quickly. Not that I'm suggesting we don't also need to reduce CO2 emissions to a sustainable level.
        • by AvitarX ( 172628 )

          I think the concern is that climate change has increased the amount of fires (record hot year) and therefore making it harder to use the forests as a sink.

          • You can also only count on growing so many trees, and that each of those trees is going to have a limit on how much CO2 they can absorb and sequester. And then yes, when you count deforestation, either through human activity or wildfires, even where everything else is equal, you're going to start hitting those limits.

    Tree continued to grow and forests continued to absorb billions of tonnes of CO2.

    But the natural output of CO2 by said forests has increased so that forests are no longer large net CO2 reducers.

    Forests used to be considered to take up about 2x more CO2 than they emitted: "Forests emitted on average 8.1 billion metric tonnes of carbon dioxide and absorbed 16 billion between 2001 and 2019." but that dynamic is what is being highlighted here.

    • by flink ( 18449 )

      I think forests being carbon sinks is only a short term artifact of the fact that we have so many young forests due to reforestation after the deforestation of the last 500 years. A mature forest is going to have as almost as much gradual CO2 release due to decay as there is capture due to growth, with an occasional rapid release due to fires. The only exception is if there is some mechanism that sequesters organic material before it can rot or burn, like a peat bog, or rivers carrying fallen trees out to

      Every bucket has a top, every system has a maximum carrying capacity. This idea that somehow because fossil fuels are relatively cheap and high density energy storage mediums, that thermodynamics somehow is magically suspended is the very core of the magical thinking of defenders of such energy sources. The physical laws of our universe don't care about our economic systems or are short term interests, or hell even our long term interests. Increase the thermal equilibrium of any system, whether a pot of water or the atmosphere and oceans of our planet, and things will heat up (in other words, more energy in the system). To deny it is to basically deny bedrock physical laws we've known about since the 19th century.

  • First of all, I am a firm believer in the effects of climate change, to the point that I'm very familiar with the Keeling curve [ucsd.edu]. A shift in 8 Gigatons per year should be noticeable, IMHO but I can't see it. Maybe another carbon sink is simultaneously increasing its capture capacity?

      Should it? 8 gigatons is a little over one part per million of the atmosphere. The winter to summer variation is about 6 ppm.

      Looking at the Keeling curve https://gml.noaa.gov/ccgg/tren... [noaa.gov] the slope is definitely increasing.

      The curve itself doesn't say whether the increase in slope is a decrease in absorption or an increase in emission, but sites I see tend to say emissions aren't increasing (e.g., https://www.carbonbrief.org/an...
