NASA Satellite Detects Tree Leaf Changes as Early Volcano Eruption Warning Signal
NASA and Smithsonian scientists find that greener trees seen in satellite images may warn of upcoming volcanic eruptions. The change is linked to rising carbon dioxide emissions from magma, which trees absorb and display through greener leaves. This method could enhance early warning systems and improve public safety near active volcanoes.

Study Finds Coronal Loop Flickers Could Predict Solar Flares Hours in Advance
NASA's Solar Dynamics Observatory has revealed a potential breakthrough in predicting solar flares. Scientists observed brightness fluctuations in coronal loops—plasma structures in the Sun's atmosphere—that intensify hours before solar flares occur. This discovery, with a prediction accuracy of 60–80%, may provide 2–6 hours of advance warn...

Study Warns Saltwater Intrusion Threatens Global Coastal Groundwater by 2100
A NASA-DOD study indicates that by 2100, 77% of global coastal aquifers will face saltwater intrusion due to rising sea levels and reduced groundwater recharge. This phenomenon, caused by shifting fresh and saltwater dynamics, threatens water quality, agriculture, and infrastructure. Low-lying regions, including Southeast Asia, the U.S. Eastern Sea...

NASA Awards Johns Hopkins University Contract for Suprathermal Ion Sensor Development
NASA has awarded a $20.5M contract to Johns Hopkins Applied Physics Laboratory to develop Suprathermal Ion Sensors under NOAA's Space Weather Next Programme. The sensors will play a pivotal role in monitoring ions and solar winds, aiding early warnings against space weather impacts. Spanning a period through 2034, the project also involves integrat...

NASA Satellites Reveal Freshwater Decline as Global Droughts and Warming Persist
NASA’s GRACE satellites have recorded a significant decline in Earth’s freshwater reserves since 2014, revealing a loss of 1,200 cubic kilometres—two and a half times the volume of Lake Erie. This trend, highlighted in the journal Surveys in Geophysics, is attributed to persistent droughts and rising global temperatures, particularly in regio...

Global Freshwater Levels Decline Since 2014, NASA-German Satellites Reveal
Data from NASA and German satellites reveal Earth's freshwater levels declined significantly after May 2014, with storage remaining persistently low. Research attributes this to global warming, major droughts, and human activity such as irrigation. The trend raises concerns over water stress, food security, and long-term environmental stability.

Severe Solar Storm Warning: NOAA Predicts Auroras Across US, Possible Power Grid Impact
NOAA has issued a warning for a severe solar storm expected to hit Earth on October 10-11, 2024. This storm, classified as G4, is caused by a coronal mass ejection from the sun, travelling at nearly 2.9 million miles per hour. It has the potential to disrupt power grids, radio communications, and satellites. Additionally, the storm could enhance au...

NASA Explains How Intense Geomagnetic Storms Lead to Stunning Auroras
The National Oceanic and Atmospheric Administration (NOAA) has issued a warning about an intense geomagnetic storm at level G4, which is likely to disrupt power grids, GPS, and radio signals. Despite these potential issues, the storm offers a remarkable visual treat with colourful auroras visible in high-latitude areas of Canada and the United Stat...
