Geophysicists Reveal Megathrust Fault Off Costa Rica
Geophysicists have obtained detailed three-dimensional images of a dangerous megathrust fault west of Costa Rica where two plates of the Earth’s crust collide. The images…

The Sun might emit less radiation by mid-century, giving planet Earth a chance to warm a bit more slowly but not halt the trend of…
For the first time, scientists have estimated how much energy is transferred from large to small scales within the magnetosheath, the boundary region between the…
A new study has found that dust, not spring warmth, controls the pace of spring snowmelt that feeds the headwaters of the Colorado River. Contrary…
Just before a surprise eruption of New Zealand’s Ruapehu volcano in 2007, seismic tremor near its crater became tightly correlated with twice-monthly changes in the…
A new international analysis of marine fossils shows that the warming of the polar oceans during the Eocene, a greenhouse period that provides a glimpse…
A new analysis by NASA shows that Earth’s global surface temperatures in 2017 ranked as the second warmest since 1880. Continuing the planet’s long-term warming…
A paper appearing in Geophysical Research Letters uses machine learning to craft an improved model for understanding geothermal heat flux — heat emanating from the…
Princeton University researchers have found that the climate models scientists use to project future conditions on our planet underestimate the cooling effect that clouds have…
Sixty-five million years ago, clouds of ash choked the skies over Earth. Dinosaurs, along with about half of all the species on Earth, staggered and…
Like Earth, space has weather. Except instead of swirling winds and downpours of precipitation, space weather is defined by shifting electric and magnetic fields and…
Using measurements from NASA’s Aura satellite, scientists studied chlorine within the Antarctic ozone hole over the last several years, watching as the amount slowly decreased….
This visualization shows the motion of one electron in the magnetic reconnection region. As the spacecraft approaches the reconnection region, it detects first high-energy particles,…
A new NASA-led study has solved a puzzle involving the recent rise in atmospheric methane, a potent greenhouse gas, with a new calculation of emissions…
In September 2017, a new iceberg calved from Pine Island Glacier—one of the main outlets where the West Antarctic Ice Sheet flows into the ocean….
What is causing the droughts that the Iberian Peninsula regularly endures? Why are the winters sometimes mild and rainy and other times cold and dry…
The air we breathe contains particulate matter from a range of natural and human-related sources. Particulate matter is responsible for thousands of premature deaths in…
A breakthrough in the understanding of how cosmic rays from supernovae can influence Earth’s cloud cover and thereby climate is published today in the journal…
