Researchers used a novel model ensemble to study compound hot-dry-events and found that precipitation trends determine their future occurrence. The frequency of these events is expected to increase fourfold in a two-degree warmer climate, with an uncertainty of up to 48% for precipitation trends.
A new study provides evidence of growth limitations in Antarctic fish, which have adapted to survive in freezing temperatures. Despite similar ecological conditions, these fish consume less food and grow at half the rate of temperate water cousins when held at the same temperature.
A new study reveals a significant shift in the Northern Hemisphere jet stream position, increasing by up to 330 km and speed by 8% during 1871-2011. This shift is linked to warming Arctic winters and decreased temperature gradients, with implications for climate predictions and storm activity.
A new study found that Amazonian forests are impacted by high maximum temperatures, causing tall trees to shed their leaves and branches. The study, led by the University of Helsinki, used LiDAR to track the effects of fragmentation and climate change on plant phenology.
A recent study by Dr. Henrik Svensmark and colleagues reveals a close connection between supernovae occurrence and the burial of organic matter in sediments on Earth. The correlation indicates that supernovae are essential for life's existence, with high nutrient concentrations leading to increased bioproductivity and oxygen production.
The study, led by Universidad Complutense de Madrid, estimates that record temperatures are eight times higher than expected without global warming. At least one in four new record rainfalls is attributed to climate change.
Scientists discovered a persistent link between Earth's orbit and millennial-scale climate variability. The study analyzed four climate-sensitive records, finding that orbital variations influenced abrupt climate events through the Pleistocene. This discovery highlights the complex interactions between orbital geometry and global glaci...
The Three Gorges Region experienced its second-highest average precipitation on record, with heavy rainstorms and floods dominating the summer of 2020. The region's ecological environment improved, with a significant weakening trend in acid rain over the past decade.
A new study finds that greenhouse warming will increase North Tropical Atlantic variability, causing more frequent extreme events like hurricanes and droughts. The research also reveals an amplification of ENSO-induced temperature anomalies due to increased ENSO variability in a warming climate.
A recent study found that greenhouse gases from human activity and warmer North Atlantic Ocean temperatures contributed to the Northeast's increased extreme precipitation since 1996. The research used global climate model simulations and statistical methods to isolate the causes of the increase.
Researchers found that accounting for climate variability increases predicted sea level rise by 2.7-4.3 inches by 2100, compared to 10.6-14.9 inches without variability. This additional ice melt will impact hurricane storm surges globally.
Using supervised learning algorithm, researchers reduced uncertainty in oceanic N2O emissions by substantial margins. The study reveals a vigorous seasonal cycle dominated by tropical and coastal upwelling regions
Climate scientists have found that individual climate models may not provide the complete picture of the Earth's climate sensitivity due to underestimated internal climate variability. Combining uncertainty from multiple models yields wider distributions, improving long-term predictions.
Research findings show that mid-high latitude climate variability significantly impacts the East Asian monsoon, with a synergistic effect on predictability sources. Chinese scientists propose new concepts to explain combined effects of regional climate variabilities on East Asian climate.
Century-scale climate variability was enhanced when the Earth was warmer during the Last Interglacial period compared to current interglacial conditions. The study reveals series of century-scale arid events in southern Europe and cold water-mass expansions in the North Atlantic.
Researchers found pink noise energy signatures in historical climate proxy data before and after the Industrial Revolution, suggesting a possible link between pink noise and Earth's climate dynamics. The study's findings could have implications for understanding 'resonances' that couple and amplify warming processes.
A recent study suggests that fructans in wheat plants hold the key to developing climate-resilient varieties with increased nutritional value. The authors propose using fructans as a breeding target to create healthier and more resilient wheat varieties.
Researchers reconstruct climate and oceanographic conditions in the westernmost Mediterranean Sea, revealing hot and dry Medieval Climatic Anomaly and cooler Little Ice Age conditions. Human impact also detected in temperature increase, aridification, and soil erosion.
A team of researchers has developed a new method to measure ecosystem sensitivity to climate variability by analyzing satellite data gathered over the past 14 years. The Vegetation Sensitivity Index (VSI) reveals ecologically sensitive regions with amplified responses to climate changes in various parts of the world.
A new study by an international team of scientists confirms that recent record warm years are almost certainly due to human-made climate change. The odds of these extreme temperature records occurring naturally are extremely low, between 1 in 5000 and 1 in 170,000.
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.
