Earth in the News
The latest reports of natural disasters and scientific discoveries about the Earth.
Scientists have made new updates to old technology that will enable weather forecasters to make improved predictions of severe weather.
Increasing energy demands and expanding industrial and agricultural activities worldwide are changing the composition of the atmosphere and contributing to major global challenges like climate change and air pollution.
Using a detection network based in Japan, scientists have uncovered a rare type of deep-earth tremor that they attribute to a distant North Atlantic storm called a 'weather bomb.' The discovery marks the first time scientists have observed this particular tremor, known as an S wave microseism.
Solar variations affect the abundance of clouds in our atmosphere, a new study suggests. Large eruptions on the surface of the Sun can temporarily shield Earth from so-called cosmic rays which now appear to affect cloud formation.
Every year, humans advance climate change and global warming by injecting about 30 billion tons of carbon dioxide into the atmosphere. Scientists believe they've found a way to convert all these emissions into energy-rich fuel in a carbon-neutral cycle that uses a very abundant natural resource: silicon. Readily available in sand, it's the seventh most-abundant element in the universe and the second most-abundant element in the earth's crust.
How many millimeters has the sea level risen? How fast are the continents moving? In order to answer these questions, measurements are being made around the clock at more than 1,700 globally distributed observing stations. These data are then evaluated by researchers. Their new realization of the global reference system that has now been published, is so exact that it even allows to detect seasonal variations.
Scientists says a new map of the ecological footprint of humankind shows 97 percent of the most species-rich places on Earth have been seriously altered.
One size does not always fit all, especially when it comes to global climate models, according to climate researchers who caution users of climate model projections to take into account the increased uncertainties in assessing local climate scenarios.
An international research project has found human activity has been causing global warming for almost two centuries, proving human-induced climate change is not just a 20th century phenomenon.
Extreme global warming 252 million years ago caused a severe mass extinction of life on Earth. It took life up to 9 million years to recover. New study finds clues in the Arctic as to why this recovery took so long.
The global impact of human activities on the natural environment is extensive, but those impacts are expanding at a slower rate than the rate of economic and population growth.
Earth's climate interacts with so called surface processes -- such as landslides or river erosion -- and tectonics to shape the landscape that we see. In some regions, the sheer force of these processes has led scientists to believe that they may even influence the development of tectonics. Scientists have now disproved this assumption.
An international team of researchers have shown that vulnerable coral populations in the eastern tropical Pacific have been completely isolated from the rest of the Pacific Ocean for at least the past two decades.
Geologists are using new direct methods to measure the Earth's oxygenation. They identified, for the first time, exactly how much oxygen was in Earth's atmosphere 813 million years ago -- 10.9 percent. This finding, they say, demonstrates that oxygenation on Earth occurred 300 million years earlier than previously concluded from indirect measurements.
The April 2015 Gorkha earthquake in Nepal killed more than 8,000 people and injured more than 21,000. With a magnitude of 7.8, it was the worst natural disaster to strike Nepal since the 1934 Nepal-Bihar earthquake. Researchers have now discovered complex relationship between major earthquake faulting and mountain building in the Himalayas.
Extreme weather conditions associated with climate change may extend the ozone season in the Southeastern United States as drought-stressed trees emit more of the precursor compound that helps form the health-threatening pollutant. July and August have traditionally been peak ozone months, but a new study suggests those peaks could extend well into the fall as weather becomes warmer and drier.
Fresh understanding of West Antarctica has revealed how the region's ice sheet could become unstable in a warming world.
On August 24, 2014, just south of Napa, California, a fault in Earth suddenly slipped, violently shifting and splitting huge blocks of solid rock, 6 miles below the surface. The underground upheaval generated severe shaking at the surface, lasting 10 to 20 seconds. When the shaking subsided, the magnitude 6.0 earthquake left in its wake crumpled building facades, ruptured water mains, and fractured roadways. Scientists now report that this earthquake continued to creep, weeks after the main shock.
This year's melt season in the Arctic Ocean and surrounding seas started with a bang, with a record low maximum extent in March and relatively rapid ice loss through May. One NASA sea ice scientist describes this as 'the new normal.'
Sea level changes in the Pacific Ocean can be used to estimate future global surface temperatures, according to a new paper. Scientists knew both the rate at which global surface temperature is rising and sea level in the Pacific varied, but had not connected the two phenomena. The researchers estimate by the end of 2016, average surface temperature will increase up to 0.5 F (0.28 C) more than in 2014.
