Orbital (Hydro)Climate Variability in the Ice-Free Early Eocene Arctic.
Paleoceanogr Paleoclimatol
December 2024
Article Synopsis
- - The study analyzes Early Eocene Arctic climate dynamics using sediments to understand climate patterns without ice, focusing on orbital variability that influenced climate changes during that period.
- - High-resolution records of lipid biomarkers and pollen indicate that temperature changes were linked to orbital cycles, with significant sea surface temperature increases tied to higher precipitation and nutrient supply in the Arctic Basin.
- - The research suggests that Arctic climate responses during the Early Eocene were significantly influenced by local insolation, showing stronger temperature variability compared to the deep ocean and tropics, even in the absence of ice-albedo feedbacks.
Light Limitation of Poleward Coral Reef Expansion During Past Warm Climates.
Geophys Res Lett
November 2024
Article Synopsis
- The distribution of modern shallow-water tropical corals is primarily influenced by temperature, thriving only in waters above 16-18°C year-round.
- Researchers tested whether solar radiation limits the spread of coral reefs toward the poles during warmer climates, using a new model for coral calcification.
- Findings indicate that calcification rates significantly decline past 40° latitude and severely drop after 50° latitude due to less winter daylight, implying that light availability restricts coral reef expansion, not temperature alone, and that fossil coral distribution is not a reliable indicator for water temperatures in these areas.
Problem: For health care providers to ensure appropriate decision-making in clinical settings during childbirth, facilitators and barriers must be identified.
Background: Women who experience a sense of control by participating in the decision-making process, are more likely to have a positive birth experience. However, decision-making may involve hierarchies of close observation and control.
The long-term effects of the Central Atlantic Magmatic Province, a large igneous province connected to the end-Triassic mass-extinction (201.5 Ma), remain largely elusive. Here, we document the persistence of volcanic-induced mercury (Hg) pollution and its effects on the biosphere for ~1.
