How shifting tectonic plates drove Earth’s climate swings

Carbon released from Earth’s spreading tectonic plates, not volcanoes, may have triggered major transitions between ancient ice ages and warm climates, new research finds.This post was originally published on this site

Surprisingly in sync: Sunlight and sediments reveal climate history of Antarctica

Phys.org

The remnants of ice attached to the coast offer astounding insights into the climate history of past millennia. An international research team led by the CNR Institute of Polar Sciences (Italy) and involving the University […]

Ecosystem productivity shapes how soil microbes store or release carbon, challenging old assumptions

Phys.org

Soils store more carbon than the atmosphere and vegetation combined, with soil microorganisms playing the main role. As a result, the global soil carbon cycle—by which carbon enters, moves through, and leaves soils worldwide—exerts a […]

Ancient CO₂ surge triggered widespread forest fires and erosion 56 million years ago

Phys.org

The climate warmed up almost as quickly 56 million years ago as it is doing now. When a huge amount of CO2 entered the atmosphere in a short period of time, it led to large-scale […]

What deep sea mud is revealing about giant earthquakes along the Pacific Coast

Phys.org

Marine turbidites are layers of mud and sand deposited on the deep ocean floor by massive underwater landslides and are often used as a historical record for reconstructing earthquake histories.This post was originally published on […]

Mount Fuji’s unique clouds: Research provides insights into frequency and formation conditions

Phys.org

Researchers at the University of Tsukuba conducted a three-year observational study (January 2019–December 2021) using a network of live cameras to monitor characteristic clouds around Mount Fuji.This post was originally published on this site

3D mapping of fault beneath Marmara Sea reveals likely sites for future earthquakes

Phys.org

According to researchers from Science Tokyo, a new three-dimensional model of the fault beneath the Marmara Sea in Turkey reveals where a future major earthquake could take place. Using electromagnetic measurements, the team mapped hidden […]

Scientists trace microplastics in fertilizer from fields to the beach

Phys.org

Researchers from Tokyo Metropolitan University have studied how polymer-coated fertilizer (PCF) applied to fields ends up on beaches and in the sea. They studied PCF deposits on beaches around Japan, finding that only 0.2% of […]

Calm seas can drive coral bleaching, research reveals

Phys.org

New research by Monash University and the ARC Center of Excellence for the Weather of the 21st Century analyzed close to three decades of weather data during the coral bleaching season and identified the prevalence […]

Japan Trench geology confirmed as key driver of 2011 megaquake

Phys.org

Geologists from Heriot-Watt are part of an international research team that has confirmed why the 2011 Tōhoku earthquake off northeast Japan behaved in such an extreme and destructive way.This post was originally published on this […]

New details capture 13 years of wage-related laws, show increased protections for workers in the US

For more than a decade, local and state laws have been increasingly focused on providing more protection and agency to workers fighting wage theft, according to new data published on LawAtlas.org and analysis in a [...]
