Monitoring strategies of suspended matter after natural and deep-sea mining disturbances

"Dust clouds" at the bottom of the deep sea, that will be created by deep-sea mining activities, descend at a short distance for the most part. That is shown by Ph.D. research of NIOZ marine geologist Sabine Haalboom, on the bottom of the Pacific Ocean.

Summers warm up faster than winters, fossil shells from Antwerp show

In a warmer climate, summers warm much faster than winters. That is the conclusion of research into fossil shells by Earth scientist Niels de Winter. With this knowledge, we can better map the consequences of current global warming in the North Sea area.

The case for sharing carbon storage risk

Even the most optimistic projections for the rapid build-out of solar, wind, and other low-carbon resources acknowledge that coal, natural gas, and other fossil fuels will dominate the world's energy mix for decades to come. If the vast greenhouse gas emissions from burning these fossil fuels continue to enter the planet's atmosphere, global warming will not be limited to sustainable levels. The capture and geologic sequestration of carbon emissions (CCS) offer a promising solution to the world's carbon conundrum.

How wildfires change soil chemistry

The huge, long-lasting wildfires that have become increasingly common in recent years can cause changes in soil chemistry that affect water contamination, air quality, and plant growth. But these changes are poorly monitored and rarely factor into post-fire recovery efforts or risk assessments, according to a review study published May 14 in Nature Reviews Earth & Environment.

Horizontal resolution affects model aerosol properties, finds Earth system model research

Earth system models are running at higher resolutions. Yet parameterizations designed to represent aerosol lifecycles and their interactions with clouds and radiation in the Energy Exascale Earth System Model (E3SM) are developed and evaluated at Earth system model scales, and their performance at higher resolution is unclear.

Research team develops an impact-based forecasting system for improved early flood warning

Climate change increases the frequency of extreme events such as flooding. This reinforces the need to develop methods for more precise and faster flood forecasting in order to better protect the population in the future.

Enhancing marine heat wave predictions with advanced ocean data assimilation

The "Blob," a significant marine heat wave in the Northeast Pacific Ocean from 2013 to 2016, had profound effects on climate and marine ecosystems. Predicting such events is challenging due to the complexity of ocean–atmosphere interactions and the need for accurate initial conditions in models.

Weaker ocean currents lead to decline in nutrients for North Atlantic ocean life during prehistoric climate change

Researchers at Georgia Institute of Technology have finished investigating how the prehistoric weakening of a major ocean current led to a decline in ocean nutrients and negative impacts on North Atlantic ocean life. The results support predictions about how our oceans might react to a changing climateβ€”and what that means for ocean life.

Alerting communities to hyperlocalized urban flooding

As climate change continues to warm the planet, scientists expect natural hazards such as flooding to increase. Urban flooding can be caused by extreme precipitation events, storm surges, or high tides, with dangerous and expensive consequences for public health and infrastructure.

Wildfires in old-growth Amazon forest areas rose 152% in 2023, study shows

Although the rate of deforestation in the Brazilian Amazon fell in 2023, the region is faced with another challenge in the shape of fire affecting the native vegetation that has so far been spared destruction. An article published in the journal Global Change Biology warns that wildfires in old-growth forests rose 152% last year compared with 2022, despite a drop of 16% in the total number of fires throughout the Amazon and a 22% drop in deforestation.

Improved wildfire smoke model identifies areas for public health intervention

The Canadian wildfires of June 2023 exposed a large portion of the Northeastern United States to unprecedented levels of smoke. A new model that combines wildfire smoke forecasts and data from ground-based sensors may help public health officials plan targeted interventions in areas most at risk for the negative health effects of unexpected smoke events and air pollution, according to a team led by Penn State scientists.

Unearthing the impacts of hydrological sensitivity on global rainfall

Georgia Tech researcher Jie He set out to predict how rainfall will change as Earth's atmosphere continues to heat up. In the process, he made some unexpected discoveries that might explain how greenhouse gas emissions will impact tropical oceans, affecting climate on a global scale.

Bleaching of coral reefs shows severe ocean circulation changes

A new paper in Oxford Open Climate Change indicates that extensive bleaching and deaths are widespread at several major coral reefs around the world. This suggests that climate change has resulted in shifting patterns in ocean circulation. Coral reefs may soon be a thing of the past.

Every drop counts: New algorithm tracks Texas's daily reservoir evaporation rates

Summer can be an extra challenging time for Texas's 189 major water supply reservoirs. With temperatures consistently reaching 100 degrees or higher, reservoir evaporation rates see high increases.
