A team proposes that the addition of a small accessory subunit to the carbon-fixing enzyme was key to improving its catalytic properties and specificity to CO₂.

While the higher temperatures and CO₂ levels associated with climate change currently fuel plant productivity, a study finds that changing conditions could take a toll on photosynthesis rates in regions outside the Arctic within a decade.

The growing season on the tundra is starting earlier as the planet warms, but the plants aren’t sequestering more carbon, a new study finds.

When soil heats up, microbes scale back protein synthesis machinery by making use of higher reaction rates that occur at higher temperatures, a study finds.

The first evidence of biologically produced elemental carbon inspires more questions than answers.  

Brood X’s emergence tunnels—numbering in the hundreds per square meter of soil—give researchers a special opportunity to study how such extreme soil aeration affects the ecosystem.

More-accurate predictions of the severity of an upcoming grass pollen season based on rainfall and temperature could help allergy sufferers manage their symptoms.

A new study finds reductions in greenhouse gases are insufficient to substantially slow warming, and the authors argue that to continue the benefits of reduced emissions, policymakers will need to adopt green economic recovery strategies.

Bacteria that take in inorganic carbon could have applications in sustainable biofuels.

Carbon dioxide and temperature need to increase in a constant ratio for plants to keep up with climate change.

The concentration of the greenhouse gas is now one-and-a-half times what it was before the Industrial Revolution, the World Meteorological Association says.

Plants use two different strategies to photosynthesize underwater.

Insulating tundra soil with snow increased the abundance of microbial species involved in carbon dioxide and methane release.

Microbiologists identify diatoms, algae, and cyanobacteria species from samples above a mountaintop in France.

A higher species richness could boost plant communities’ ability to mitigate climate change, a study suggests.

Researchers predict that activity around the digital currency could single-handedly push warming above 2 °C within 30 years, but other experts say the conclusion is flawed.

With samples taken from the crust of the Mid-Atlantic Ridge, researchers have discovered where some of the oceans’ dissolved organic carbon winds up.

A study of 686 fish and invertebrates predicts that some animals will have to shift more than 1,000 kilometers to stay within tolerable temperatures.

Researchers exposed a coral reef to carbonated water to study the effects of ocean acidification.
