Antarctic ice shelves hold twice as much meltwater as previously thought      (via sciencedaily.com)     Original source 

Slush -- water-soaked snow -- makes up more than half of all meltwater on the Antarctic ice shelves during the height of summer, yet is poorly accounted for in regional climate models. The findings could have profound implications for ice shelf stability and sea level rise.

Groundbreaking discovery: Zinc can make crop yields more climate-resilient      (via sciencedaily.com)     Original source 

Climate change, drought, increased temperature and other stressors challenge agricultural sustainability. Researchers have now made an unexpected discovery: zinc plays a pivotal role in the plant response to abiotic stress. This groundbreaking discovery not only sheds light on the intricate mechanisms of plant growth but also holds promise for revolutionizing crop resilience, especially in legume-based agriculture.

New twists on tornadoes: Earth scientist studies why U.S. has so many tornadoes      (via sciencedaily.com)     Original source 

Across the Midwest during the warmer months, studying the sky for signs of storms and tornadoes becomes one of the most popular pastimes. Working at the intersection of climate science and meteorology and using modeling, scientists are looking at the big picture of what causes severe storms and tornadoes -- and what dictates where they occur.

Climate change and sea level rise pose an acute challenge for cities with combined sewer systems      (via sciencedaily.com)     Original source 

Older coastal cities, like Philadelphia, New York and Boston are at risk of being inundated by untreated sewage during floods. Due in part to the design of their combined sewer systems and in part due to sea level rise, these cities could be facing a growing public health crisis as climate change also drives more extreme precipitation. The group recently published research that modeled the potential extent of the problem in a section of the coastal city of Camden, New Jersey, and the effectiveness of one proposed intervention to help protect these communities.

For many urban residents, it's even hotter than their weather app says      (via sciencedaily.com)     Original source 

There's a strong chance that last week's scorching temperatures were even hotter than reported for those living in underserved urban areas. New research from environmental engineers has shown that citizen science tools used to gauge heat in these urban areas likely understate the problem of heat islands due to a lack of weather stations. The researchers also suggest a statistical method to improve estimates of urban heat.

Restoring the Great Salt Lake would have environmental justice as well as ecological benefits      (via sciencedaily.com)     Original source 

Inland seas around the world are drying up due to increasing human water use and accelerating climate change, and their desiccation is releasing harmful dust that pollutes the surrounding areas during acute dust storms. Using the Great Salt Lake in Utah as a case study, researchers show that dust exposure was highest among Pacific Islanders and Hispanic people and lower in white people compared to all other racial/ethnic groups, and higher for individuals without a high school diploma. Restoring the lake would benefit everyone in the vicinity by reducing dust exposure, and it would also decrease the disparities in exposure between different racial/ethnic and socioeconomic groups.

Understanding the Green Sahara's collapse      (via sciencedaily.com)     Original source 

Abrupt shifts within complex systems such as the Earth's climate system are extremely hard to predict. Researchers have now succeeded in developing a new method to anticipate such tipping points in advance. They successfully tested the reliability of their method using one of the most severe abrupt climate changes of the past: the shift of the once-green Sahara into a desert.

Quantum data assimilation: A quantum leap in weather prediction      (via sciencedaily.com)     Original source 

Data assimilation is an important mathematical discipline in earth sciences, particularly in numerical weather prediction (NWP). However, conventional data assimilation methods require significant computational resources. To address this, researchers developed a novel method to solve data assimilation on quantum computers, significantly reducing the computation time. The findings of the study have the potential to advance NWP systems and will inspire practical applications of quantum computers for advancing data assimilation.

New coral disease forecasting system      (via sciencedaily.com)     Original source 

Research has led to a new tool for forecasting coral disease that could help conservationists step in at the right times with key interventions. Ecological forecasts are critical tools for conserving and managing marine ecosystems, but few forecasting systems can account for the wide range of ecological complexities in near-real-time.
