A hard look at geoengineering reveals global risks
University of California - Santa BarbaraPeer-Reviewed Publication
With CO2 emissions continuing unabated, an increasing number of policymakers, scientists and environmentalists are considering geoengineering to avert a climate catastrophe. Such interventions could influence everything from rainfall to global food supplies, making the stakes enormous. In brief, manipulating other aspects of Earth’s climate system might reduce some effects of climate change. But the wondrous complexity of our planet complicates every one of these proposals.

Climate change could drastically reduce aquifer recharge in Brazil
Fundação de Amparo à Pesquisa do Estado de São PauloPeer-Reviewed Publication
Study shows that most of the country’s underground reservoirs will lose their capacity for renewal, increasing the risk of water shortages in several regions, especially the Southeast and South. One strategy to address the problem is “managed recharge,” which includes techniques that promote the infiltration of rainwater or even treated sewage.

AI boosts National Weather Model flood prediction accuracy sixfold
American Geophysical UnionPeer-Reviewed Publication
A new machine learning tool can reduce errors in national flood prediction programing, resulting in more accurate predictions of where floods will occur. In a new study published in AGU Advances, scientists found that when the AI was used in combination with the National Water Model, developed by the U.S. National Oceanic and Atmospheric Administration, the resulting hybrid model was four to six times more accurate.

Chapman University research reveals tropical rainforest soils may fuel climate change as the Earth warms – Accelerating global warming
Chapman UniversityPeer-Reviewed Publication
Chapman University researchers, in collaboration with the U.S. Forest Service and others, published a study in Nature Communications showing that warming tropical rainforest soils release vast amounts of carbon dioxide, potentially accelerating climate change. In Puerto Rico, experimentally heated plots showed a 42–204% increase in soil respiration, among the highest CO₂ release rates ever recorded. The findings suggest that instead of acting as carbon sinks, tropical soils could become major carbon sources, intensifying global warming. Chapman’s Dr. Christine Sierra O’Connell co-led the research as part of the TRACE project.

MIT geologists discover where energy goes during an earthquake
Massachusetts Institute of TechnologyPeer-Reviewed Publication
Studying miniature analogs of natural earthquakes in the lab, MIT geologists quantified how much energy from the quake goes into heat, shaking, and fracturing. The research could help seismologists predict the likelihood of quakes in seismically active regions.

Warming temps alone fail to trigger increased CO2 levels from soil
North Carolina State UniversityPeer-Reviewed Publication
Higher temperatures combined with added carbon – and added nutrients – led to higher carbon dioxide levels released from the soil.
