Will we soon be forced to eat jellyfish? Since the beginning of the 2000s, these gelatinous creatures have invaded many of the world's seas, like the Japan Sea, the Black Sea, the Mediterranean Sea, etc. Is it a cyclic phenomenon, caused by changes in marine currents or even global warming? Until now, the causes remained unknown. A new study exposes overfishing as the main factor.
Scientists have found unsuspected linkages between the oxidation state of iron in volcanic rocks and variations in the chemistry of the deep Earth. Not only do the trends run counter to predictions from recent decades of study, they belie a role for carbon circulating in the deep Earth.
It may be the 21st century, but nearly half the world's population still cooks and heats with open fires or primitive stoves that burn wood, animal dung, charcoal and other polluting solid fuels. A new article describes impressive progress being made to remedy that situation and the obstacles that remain.
Deposits left by the eruption of a subglacial volcano, or tuya, 1.8 million years ago could hold the secret to more accurate palaeo-glacial and climate models, according to new research.
Details are emerging from a recent research expedition to the Sub-Tropical North Atlantic. The objective of the expedition was to study the salt concentration (salinity) of the upper ocean. Scientists explored the essential role of the ocean in the global water cycle.
US residents who believe in the scientific consensus on global warming are more likely to support government action to curb emissions, regardless of whether they are Republican or Democrat, according to a new study.
The Finnish Meteorological Institute has updated its estimates concerning the impact of rising sea levels on the Finnish coast. Post-glacial rebound and changes in the Earth’s gravity field protect the Finnish coast against rising sea levels, especially in the Gulf of Bothnia. In the Gulf of Finland, the sea level is starting to rise.
As temperatures warm, plants release gases that help form clouds and cool the atmosphere, according to new research. The new study identified a negative feedback loop in which higher temperatures lead to an increase in concentrations of natural aerosols that have a cooling effect on the atmosphere.
Sea surface temperatures in the Northeast Shelf Large Marine Ecosystem during 2012 were the highest recorded in 150 years, according to new research. Temperature is also affecting distributions of fish and shellfish on the Northeast Shelf.
Researchers have employed a novel measurement device for new studies in Alaska.
