Junior Professor Denis Scholz will continue speleothem research, extending it to longer-term objectives. Speleothems are suitable archives of past climate variability due to their global distribution and precise dating capabilities.
Researchers discovered a significant drop in CO2 levels at the end of the Ordovician Period, preceding an ice age and mass extinction. This finding can help climatologists predict future environmental changes by understanding past carbon cycles.
Researchers found longer, less frequent climate fluctuations contribute to abrupt and unexplained ecosystem shifts in the North Pacific. The study suggests changing climate variability contributed to 1977 and 1989 regime changes with more likely larger climate-triggered shifts.
A new study found that climate variability historically accounts for one-third of yield variability for maize, rice, wheat, and soybeans worldwide. The equivalent of 36 million metric tons of food is lost each year due to climate-related crop yield fluctuations.
A new study reveals that Pine Island Glacier is highly sensitive to climatic and oceanic changes, with fluctuations in ocean heat causing significant melting. The glacier's response to climate variability has been underestimated, suggesting a more complex interplay between geological, oceanographic, and climatic processes.
A study by the University of Zurich found that climate variability accounts for 54% of global vegetation activity changes. Human activity caused over 30% of changes, with regions such as Tanzania and Zimbabwe experiencing declines in vegetation activity. The research team will further investigate interactions between humans and climate.
A team of scientists predicts that Earth's climate has undergone rapid transitions over the last 800,000 years, with evidence from ancient snow layers and volcanic eruptions. The study extends the current 100,000-year record to create a new testing ground for climate models.
A new study reveals that climate change has strengthened the connection between El Nino-Southern Oscillation (ENSO) and cholera cycles, leading to increased disease outbreaks in warmer years. The researchers found that ENSO events trigger cholera increases after warm events and decreases after cold events.
The Mid-Atlantic Regional Assessment of climate change impacts identifies severe consequences for the region's population and ecosystems. The study finds that rising temperatures, sea-level rise, and extreme weather events will have devastating effects on agriculture, water resources, and coastal communities.
