Peter Wilf, a renowned paleobotanist, has been awarded the prestigious Distinguished Speaker honor by the Paleontological Society. His research on ancient plants and terrestrial ecosystems will be showcased through three lectures, shedding light on biodiversity, climate change, and extinction.
Researchers estimate that the 60-million-year-old Titanoboa cerrejonensis snake would have required an average annual temperature of 30-34°C to survive. Its size is comparable to that of today's anacondas and reticulated pythons, but its discovery challenges our understanding of climate and species adaptation.
The Geosphere journal features two studies: one on climate change in the southwestern US from 17-6 million years ago, and another on the evolution of the South Balkan extensional system. The climate study used sedimentation and erosion history to interpret changes in ocean circulation and North American monsoon activity.
A team of researchers used oceanographic data to predict the potential consequences of climate change on a global scale. They found that if current trends continue, altered ocean circulation could lead to dramatic implications for the world's climate and biosphere.
Researchers reconstructed Arctic climate patterns over 65 million years, revealing a link between Arctic cooling and global cooling. Changes in ocean circulation could lead to abrupt changes in climate, similar to those that occurred at the onset of the last ice age.
Researchers discovered three periods of high vegetation cover in the Sahara Desert over the past 120,000 years, tied to changes in Earth's rotation axis and increased precipitation. Computer model simulations support these findings, suggesting a potential expansion of vegetation in the region under human-driven climate change.
A long-term study of mammal fossils in northern Pakistan reveals a significant decline in diversity after climate change precipitated a shift in vegetation. The research, spanning 5 million years, shows that mammals that relied on fruit and browse disappeared early, while those that ate grass adapted or went extinct.
Recent studies shed new light on the late Paleozoic ice age, revealing a dynamic icehouse regime and challenging traditional interpretations. This improved understanding can aid in preparing for rising atmospheric carbon dioxide levels and global temperature increases.
A 120-foot sediment core from the Gulf of Guinea reveals a 155,000-year record of continuous monsoon history, tied to Northern Hemisphere climate shifts and local solar radiation. The study demonstrates the sensitivity of the monsoon region to global climate conditions.
Researchers have gathered quantitative temperature data from arctic lake sediments and glaciers, revealing temperatures five degrees warmer than today. This finding provides a climate analogue to inform future predictions, highlighting the exceptional magnitude and rate of warming in the Arctic.
Researchers from Indiana University and Royal Netherlands Institute for Sea Research found evidence of dramatic climate changes during the Mesozoic Era, with temperature variations ranging from 30 deg C to 36 deg C. The discovery suggests that global fluctuations in carbon cycling played a significant role in shaping ancient climates.
Researchers identify a previously unrecognized link between mid-latitude climate dynamics and tropical African climate, leading to exceptionally high organic carbon burial. The study suggests that changes in atmospheric pressure systems and surface winds drive variations in precipitation and runoff patterns.
Scientists have found that temperature variations are more intimately linked across time scales than previously thought. The researchers used measurements from corals, ice cores, and sediment cores to estimate past temperatures, revealing a stronger connection between annual and decadal cycles.
A new study suggests that natural climate change may be more significant than previously thought, with a notable cold period in the 17th century and similarities between historical reconstructions and computer simulations. The findings highlight the importance of considering natural variability in future climate scenarios.
The thermohaline circulation plays a vital role in maintaining current climate patterns. A shutdown could lead to regional climate change and extreme weather events in eastern North America and western Europe.
Ocean drilling research advances understanding of rapid climate change, including the Paleocene-Eocene Thermal Maximum. The study also explores climate triggers and effects on various scales, from tectonic uplift to human history. Additionally, new findings challenge traditional theories on volcanic regions.
Leading climate scientists endorse the position on climate change and greenhouse gases taken by AGU in 1998, stating that natural factors cannot fully explain recent warming. They argue that proxy data must be assessed for temperature variability and hemispheric mean temperature should be distinguished from regional temperature anomalies.
Researchers used coral reefs to study the impact of hurricanes on ocean health and climate patterns. By comparing high- and low-frequency hurricane areas, they established a model for analyzing older fossil reefs.
A team of paleoecologists from Amsterdam used pollen grains to accurately recreate the local climate in Southern Mexico and Northern Guatemala around 1000 AD. The study suggests that the collapse of the well-organised Maya empire led to widespread destruction of wildlife and agricultural areas, resulting in a drier climate.
Researchers reconstruct past temperature changes using high-precision equipment, revealing a 4.5F warmer climate 5000 years ago and a 2F colder Little Ice Age. The region surrounding the North Atlantic Ocean is particularly sensitive to climatic changes due to ocean circulation patterns.
A team of researchers, led by Maureen E. Raymo, have discovered millennial-scale climate instabilities that existed much further back in time than previously thought. These rapid climate fluctuations were found to be tied to changes in ocean circulation and heat transfer.
Researchers use numerical simulations to show connection between Earth's changing shape and gravitational effects of other bodies in the Solar System. The study reveals that changes in the Earth's axial tilt can produce large changes in climate.
