Melting of polar ice shifting Earth itself, not just sea levels
The melting of polar ice is not only shifting the levels of our oceans, it is changing the planet Earth itself. Newly minted Ph.D. Sophie Coulson and her colleagues explained in a recent paper in Geophysical Research Letters that, as glacial ice from.....»»

New computer algorithm supercharges climate models and could lead to better predictions of future climate change
Earth System Models—complex computer models that describe Earth processes and how they interact—are critical for predicting future climate change. By simulating the response of our land, oceans and atmosphere to manmade greenhouse gas emissions,.....»»
Start today: Save with Dell and shape a more sustainable future for us all
The Dell sustainability mission for Earth Day 2024 means you can save while also remaining eco-conscious, something we desperately need in today's world......»»
Launch date set for NASA"s PREFIRE mission to study polar energy loss
NASA and Rocket Lab are targeting no earlier than Wednesday, May 22, 2024, for the first of two launches of the agency's PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission to study heat loss to space in Earth's polar regions......»»
Scientists show that ancient village adapted to drought, rising seas
Around 6,200 BCE, the climate changed. Global temperatures dropped, sea levels rose and the southern Levant, including modern-day Israel, the Palestinian territories, Jordan, Lebanon, southern Syria and the Sinai desert, entered a period of drought......»»
An AI model to reduce uncertainty in evapotranspiration prediction
When scientists look at the Earth's available water for ecosystem services, they don't just look at precipitation. They must also account for water moving from the ground to the atmosphere, a process known as evapotranspiration (ET)......»»
How the plant world shapes the climate cycle
In order to understand the Earth's resilience, researchers at ETH Zurich are modeling climate changes from times long past. And they show that plants are not simply victims of circumstances, but have helped to shape climate conditions on Earth......»»
NASA lays out how SpaceX will refuel Starships in low-Earth orbit
"The fundamental flow mechanism is the pressure delta across the umbilical." Enlarge / Artist's illustration of two Starships docked belly-to-belly in orbit. (credit: SpaceX) Some time next year, NASA believes SpaceX wi.....»»
Maps developed with artificial intelligence confirm low levels of phosphorus in Amazonian soil
As the impacts of climate change increasingly affect the daily lives of residents in several countries, including Brazil, the resilience of forests, especially tropical ones such as the Amazon, has become a frequent topic of research. In addition to.....»»
Hubble spots magnificent barred galaxy NGC 2217
The magnificent central bar of NGC 2217 (also known as AM 0619-271) shines bright in the constellation of Canis Major (The Greater Dog), in this image taken by the NASA/ESA Hubble Space Telescope. Roughly 65 million light-years from Earth, this barre.....»»
How did the early Great Barrier Reef manage rapid environmental change?
As the modern Great Barrier Reef emerged after the last ice age, it had to cope with multiple environmental stresses—rising sea levels, increased sediment from a flooding coastline, ocean turbulence and likely warming oceans......»»
Study provides new global accounting of Earth"s rivers
A study led by NASA researchers provides new estimates of how much water courses through Earth's rivers, the rates at which it's flowing into the ocean, and how much both of those figures have fluctuated over time—crucial information for understand.....»»
Fruit fly helps unlock clues about how organs, tissue and cancer grow
The fruit fly, Drosophila, has been used by scientists for more than 100 years to unravel key features of life on Earth, such as how animals respond to the sun and how the bodies of animals are patterned from head to tail......»»
Human activities have an intense impact on Earth"s deep subsurface fluid flow
The impact of human activities—such as greenhouse gas emissions and deforestation—on Earth's surface have been well-studied. Now, hydrology researchers from the University of Arizona have investigated how humans impact Earth's deep subsurface, a.....»»
Here"s why we should put a gravitational wave observatory on the moon
Scientists detected the first long-predicted gravitational wave in 2015, and since then, researchers have been hungering for better detectors. But the Earth is warm and seismically noisy, and that will always limit the effectiveness of Earth-based de.....»»
Mapping the Milky Way"s magnetic field in 3D
We are all very familiar with the concept of the Earth's magnetic field. It turns out that most objects in space have magnetic fields but it's quite tricky to measure them. Astronomers have developed an ingenious way to measure the magnetic field of.....»»
