How did the early Great Barrier Reef manage rapid environmental change?

The study found that elevated nutrient levels impacted reef growth, leading to the establishment of slower-growing and more sediment-tolerant coral communities in deeper water. This provides evidence on early Holocene water quality and demonstrates the capacity of the reef to grow under conditions typically considered unsuitable.

Study reshapes understanding of mass extinction in Late Devonian era

Researchers have long debated the cause of the Late Devonian mass extinction event, with some attributing it to large-scale volcanic eruptions and others to a mass deoxygenation event caused by land plants. A new study now posits that both factors played a role, highlighting the environmental tipping points the planet faces today.

How a climate model can illustrate and explain ice-age climate variability

Researchers used a well-tested climate model to depict changes in natural climate variability during the last peak glacial period. The study found that internal mechanisms, such as variations in salinity and temperature, drove the multi-centennial climate variability, resulting in fluctuations in sea ice extent and Greenland temperatures.

Giant planets cast a deadly pall

New studies show that giant gas planets in nearby star systems can prevent life on smaller, rocky planet neighbors by kicking them out of orbit and wreaking havoc on their climates. Researchers found that four giant planets in the HD 141399 system are likely to destroy the chances for life on Earth-like planets.
