Already, land-based plants absorb about one-third of the carbon dioxide (CO2) attributable to fossil-fuel burning worldwide. Understanding what might limit their ability to sequester carbon is therefore an enormously consequential line of research.
Aug 27, 2021 · The desire for unseasonal flowers supports a carbon-and-chemical-heavy global trade. In the UK, according to government statistics, the cut-flower and ornamental plant market was worth...

Researchers that studiedhundreds of plant species between 1980 and 2017 found that most unfertilized terrestrial ecosystems are becoming deficient in nutrients, particularly nitrogen. They attributed this decrease in nutrients to global changes, including rising temperatures and CO2 levels. Nitrogen is the most abundant element on Earth, making up ...
Griffin’s work also found that the temperature response of nitrogen fixation is independent from the temperature response of photosynthesis, which involves enzymes made with nitrogen. Higher temperatures can make these enzymes less efficient. Rubisco is the key enzyme that helps turn carbon dioxide into carbohydrates in photosynthesis, but as tempe...
Climate change will bring more frequent and severe extreme weather events, including extreme precipitation, wind disturbance, heat waves, and drought. Extreme precipitation events can disturb plant growth, particularly in recently burned forests, and make plants more vulnerable to flooding and soils to erosion. More frequent high winds can stress t...
While some crop yields may increase, rising CO2 levels affect the level of important nutrients in crops. With elevated CO2, protein concentrations in grains of wheat, rice and barley, and in potato tubers decreased by 10 to 15 percent in one study. Crops also lose important minerals including calcium, magnesium, phosphorus, iron, and zinc. A 2018 s...
May 5, 2021 · On top of pollutants and water use, flowers can generate serious carbon emissions because of refrigeration and long-haul transport. Stems may be transported up to 6,000 miles in refrigerated airplane holds.
Dec 8, 2021 · Because carbon dioxide stays in the atmosphere decades longer than other greenhouse gases driving global warming, efforts to reduce it are critical to mitigating climate change. Plants, through photosynthesis, and soils sequester roughly a third of carbon dioxide emissions released into the atmosphere each decade from the burning of fossil fuels.
Nov 17, 2023 · The world’s vegetation has a remarkable ability to absorb carbon dioxide (CO₂) from the air and store it as biomass. In doing so, plants slow down climate change since the CO₂ they take up does...

Oct 10, 2023 · Carbon capture technologies will be part of the solution in the long term but are still in their infancy, unproven, and in no way ready to absorb the amount of carbon dioxide needed – even with the required reduction and halting of harmful emissions – to keep us on track for a 1.5-degree pathway.
