Carbon cycle
Global average carbon dioxide reached a record high of 422.7 parts per million (ppm), marking a significant milestone in atmospheric carbon concentration.
|
| 2022 |
Carbon sequestration
A certification organization published methodological guidelines for biomass burial, providing formal frameworks for carbon sequestration techniques.
|
| 2022 |
Carbon sequestration
IPCC Sixth Assessment Report completely omitted any mention of 'ocean storage' in its Carbon Dioxide Removal taxonomy.
|
| 2022 |
Carbon sequestration
Ocean fertilization research status changed: approach of using iron fertilization to encourage phytoplankton blooms for carbon sequestration was no longer being actively pursued.
|
| 2021 |
Crassulacean acid metabolism
First genome of a quillwort (Isoetes taiwanensis) was interpreted, suggesting CAM as an example of convergent evolution in this plant species.
|
| 2021 |
C4 carbon fixation
The UK Government provided £1.2 million to study C2 photosynthesis engineering as a potential intermediate approach for rice conversion.
|
| January 20 2021 |
Carbon sequestration
United States issues Executive Order 13990, which focuses on protecting public health and environment, and specifically addresses carbon sequestration through conservation and restoration of carbon sink ecosystems like wetlands and forests.
|
| 2020 |
Carbon cycle
Human activities increased atmospheric carbon by nearly 50%, primarily through carbon dioxide emissions from burning fossil fuels and concrete manufacturing.
|
| 2020 |
Carbon cycle
Carbon dioxide in the atmosphere increased nearly 52% over pre-industrial levels, contributing to global warming and significant environmental changes.
|
| 2020 |
Carbon sequestration
The FAO reported the total carbon stock in forests had decreased to 662 gigatonnes from 668 gigatonnes in 1990.
|
| 2020 |
Carbon sequestration
A report estimated the cost of carbon sequestration in forests, ranging from US$35 per tonne for small quantities to US$280 per tonne for 10% of the total carbon required to limit global warming to 1.5°C, while also noting the risk of forest fires potentially releasing stored carbon.
|
| 2019 |
Carbon cycle
International efforts under the Montreal Protocol and Kyoto Protocol continue to control the growth of environmentally potent halocarbon gases.
|
| 2019 |
Carbon cycle
Halocarbons account for approximately 10% of total direct radiative forcing from long-lived greenhouse gases, highlighting their significant environmental impact.
|
| 2019 |
C4 carbon fixation
The Bill & Melinda Gates Foundation granted an additional US$15 million to the Oxford-University-led C4 Rice Project, with the goal of establishing experimental field plots in Taiwan by 2024.
|
| 2019 |
RuBisCO
First robust and reliable engineering of RuBisCO and other enzymes in the C3 cycle was achieved through a synthetic biology approach.
|
| 2019 |
Carbon sequestration
Forests were found to take up a third less carbon compared to the 1990s, due to higher temperatures, droughts, and deforestation. Global greenhouse gas emissions from tropical rainforest damage were substantially underestimated.
|
| 2018 |
Photoinhibition
Glowacka et al. performed research demonstrating that higher concentrations of PsBs protein can inhibit stomatal aperture without affecting CO2 intake, and improve water use efficiency in Nicotinana tabacum through genetic modifications and protein expression studies.
|
| 2016 |
Photoinhibition
Tibiletti et al. conducted studies on the PsBs protein in Chlamydomonas reinhardtii, using SDS-PAGE and immunoblot assays to locate the protein and determine its role in sensing pH changes and rapidly accumulating in high light conditions.

Bionic Leaf
Nocera's team developed 'Bionic Leaf 2.0' with a new catalyst designed to be non-harmful to the bacteria, improving the device's ability to convert CO2 into alcohol fuels or chemicals.
|
| 2015 |
Bionic Leaf
The first version of the Bionic Leaf was created, though its initial catalyst was harmful to the bacteria.
|
| 2014 |
RuBisCO
Two transplastomic tobacco lines were created by replacing RuBisCO with large and small subunit genes from the cyanobacterium Synechococcus elongatus PCC7942 (Se7942). The mutants had increased carbon fixation rates but grew more slowly than wild-type plants.
|
| 2014 |
Carbon sequestration
IPCC Fifth Assessment Report no longer mentioned the term 'ocean storage' in its climate change mitigation methods report.
|
| 2012 |
C4 carbon fixation
The Government of the United Kingdom and the Bill & Melinda Gates Foundation provided US$14 million over three years to support the C4 Rice Project at the International Rice Research Institute.
|
| 2012 |
Bionic Leaf
Nocera moved to Harvard, and The Silver Lab of Harvard Medical School joined his team to expand the artificial leaf technology.
