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."

Then there is another fact: CO2 does absorb electromagnetic waves in the near Infrared, especially between wavelengths of 13 to 17 micrometers, which corresponds to a black body of a temperature between 170 K and 220 K. The actual average temperature of Earth's surface is about 290 K, but 170 K - 220 K is the temperature range of Earth's tropopause. Basically, CO2 blocks all temperature radiation from below the tropopause. Earth's atmospheric temperature in the troposphere follows an adiabatic law, which means that a higher tropopause means higher surface temperatures. Or to be more clear, the tropopause appears, because of the absorption properties of Earth's troposphere.
Those are facts you can check yourself too. Fill a balloon with hydrogen or helium, use a thermometer and an antenna as payload and record a temperature profile of Earth's atmosphere!
You can also check at what rate different type of plants absorb CO2 at which temperatures. You will notice that for instance monocots, which include most of our common crops like wheat, corn and rice, have their optimum at lower temperatures than eudicots. which means that at higher temperatures, we would have to shift our nutrition to new types of plants. Ever wondered why most ancient civilizations we know of started out in subtropic or moderate climate? Because monocots in general generate higher yields from farming - also a fact you can check for yourself.
No, this is still not fearmongering. It's a list of facts. The fear might arise if you are wondering what this means for our future.

As in we added more CO2 last year, and plant and forrest life produced as much CO2 as it absorbed (Due to forst, plants, and soil expelling CO2 due to drought/fire/deforestation) etc.
