An international team of researchers has found that some of the oldest terrain on Venus, known as tesserae, have layering that seems consistent with volcanic activity. The finding could provide insights into the enigmatic planet's geological history.
In a simulation study, UTokyo researchers showed that limiting global warming to 1.5°C rather than 2°C will mitigate aridification in some regions of the world including the Mediterranean, western Europe, and southern Africa. However, Australia and some parts of Asia were simulated to become wetter rather than drier at both 1.5°C and 2°C of warming. These findings reveal the importance of targeted regional simulations of aridity levels to support policymaking decisions on global warming targets.
New research from the University of Washington shows that a wide variety of marine animals -- from vertebrates to crustaceans to mollusks -- already inhabit the maximum range of breathable ocean that their physiology will allow. The findings provide a warning about climate change: Since warmer waters will harbor less oxygen, some stretches of ocean that are breathable today for a given species may not be in the future.
Expanding the protected areas by 1% could save most remaining primary forests in Europe. This is the main result of researchers from the German Centre for Integrative Biodiversity Research (iDiv), Martin Luther University Halle-Wittenberg, Humboldt-University Berlin and others. This first assessment of the conservation status of Europe's primary forests identifies protection gaps and areas with restoration needs to enable the implementation of the new EU Biodiversity Strategy.
Researchers compared changes from 2000 to 2017 in premature deaths in the US due to drug poisonings, suicide and alcohol-induced causes by geographic areas and demographic characteristics.
People are starting almost all the wildfires that threaten US homes, according to an innovative new analysis combining housing and wildfire data. Through activities like debris burning, equipment use and arson, humans were responsible for igniting 97% of home-threatening wildfires, a University of Colorado Boulder-led team reported this week in the journal Fire.
The Ob, Yenisei, and Lena rivers flow into the Kara and Laptev seas and account for about half of the total freshwater runoff to the Arctic Ocean. The transport and transformation of freshwater discharge in these seas have a large impact on ice formation, biological productivity, and many other processes in the Arctic. Russian researchers have investigated the spreading of large river plumes -- that is, freshened water masses formed as a result of river runoff mixing with ambient saltwater -- in the Russian Arctic seas.
Continued volcanic activity after the collapse of a volcano has not been documented in detail so far. Now and for the first time, researchers from the German Research Center for Geosciences GFZ and Russian volcanologists are presenting the results of a photogrammetric data series spanning seven decades for the Bezymianny volcano, Kamchatka, in the journal "Nature Communications Earth and Environment".
Land development in New Jersey has slowed dramatically since the 2008 Great Recession, but it's unclear how the COVID-19 pandemic and efforts to fight societal and housing inequality will affect future trends, according to a Rutgers co-authored report.
A global analysis reveals for the first time that across almost all tree species, fast growing trees have shorter lifespans. This international study further calls into question predictions that greater tree growth means greater carbon storage in forests in the long term.
