Earth in the News
The latest reports of natural disasters and scientific discoveries about the Earth.
Accurately modeling climate change and interactive human factors -- including inequality, consumption, and population -- is essential for the effective science-based policies and measures needed to benefit and sustain current and future generations. A recent study presents extensive evidence of the need for a new paradigm of modeling that fully incorporates the feedbacks between Earth systems and human systems.
Researchers have just completed a multiyear study to identify the 'best' candidates for future use as air conditioning refrigerants that will have the lowest impact on the climate.
Seagrass meadows -- bountiful underwater gardens that nestle close to shore and are the most common coastal ecosystem on Earth -- can reduce bacterial exposure for corals, other sea creatures and humans, according to new research.
Researchers have completed the first flights of a NASA-led field campaign that is targeting one of the biggest gaps in scientists' understanding of Earth's water resources: snow.
Bias introduced through analyzing the magnetism of old rocks may not be giving geophysicists an accurate idea of how Earth's magnetic dynamo has functioned. A team has shown there is a way to improve the methodology to get a better understanding of the planet's geodynamo.
New research findings explain an Ice Age paradox and add to the mounting evidence that climate change could bring higher seas than most models predict.
The ongoing global change causes rising ocean temperatures and changes the ocean circulation. Therefore less oxygen is dissolved in surface waters and less oxygen is transported into the deep sea. This reduction of oceanic oxygen supply has major consequences for the organisms in the ocean. Scientists have now published the most comprehensive analysis on oxygen loss in the world's oceans and their cause so far.
Based on data from the first ocean sensors deployed under Greenland's Petermann Glacier, researchers report that the floating ice shelf is strongly coupled, or tied, to the ocean below and to the adjacent Nares Strait. Warming temperatures recorded at the deepest ocean sensors match data from Nares Strait, which connects the Arctic and Atlantic oceans.
A new study shows that high-resolution models captured hurricanes and big waves that low-resolution ones missed. Better extreme wave forecasts are important for coastal cities, the military, the shipping industry, and surfers.
Ice loss from Canada's Arctic glaciers has transformed them into a major contributor to sea level change, new research has found. From 2005 to 2015, surface melt off ice caps and glaciers of the Queen Elizabeth Islands grew by an astonishing 900 percent.
As the world continually emits carbon dioxide into the atmosphere, the oceans are taking a hit, absorbing some of it and growing more acidic. Among other effects, scientists have found that coral reefs and oyster hatcheries are deteriorating as a result. However, scientists studying a type of sea snail report a bit of bright news: The animal can adapt by rejiggering its shell-making process and other functions.
Surprising new evidence derived from ancient ceramics proves that the Earth's geomagnetic force fluctuates -- not diminishes -- over time, researchers say.
Seismicity in the Pacific Northwest is well documented and includes recent seismic activity on fault systems within the Juan de Fuca Strait. However, the seismic potential of crustal faults within the forearc of the northern Cascadia subduction zone in British Columbia has remained elusive.
Researchers found sunlight converted little if any permafrost thawed carbon to carbon dioxide, whereas microbes were shown to rapidly convert permafrost carbon to carbon dioxide.
By using high-res images taken by the latest generation of compact satellites, scientists have developed a new capability for estimating crop yields from space.
Crustaceans from the deepest ocean trenches found to contain ten times the level of industrial pollution than the average earthworm, scientists have shown.
Scientists have discovered that tiny marine bacteria can synthesize one of Earth's most abundant sulfur molecules, which affects atmospheric chemistry and potentially climate. This molecule, dimethylsulfoniopropionate is an important nutrient for marine microorganisms and is the major precursor for the climate-cooling gas, dimethyl sulfide.
Large numbers of threatened species have already been impacted by climate change, new research concludes. Alarmingly, this team of international researchers found evidence of observed responses to recent climate changes in almost 700 birds and mammal species.
Even though it is hotter than the surface of the Sun, the crystallized iron core of the Earth remains solid. A new study may finally settle a longstanding debate over how that's possible, as well as why seismic waves travel at higher speeds between the planet's poles than through the equator.
Scientists uncover huge 1.8 million square kilometers reservoir of melting carbon under Western United States
New research describes how scientists have used the world's largest array of seismic sensors to map a deep-Earth area of melting carbon covering 1.8 million square kilometers. Situated under the Western US, 350km beneath Earth's surface, the discovered melting region challenges accepted understanding of how much carbon Earth contains -- much more than previously understood.
