Human activity caused the long-term growth of greenhouse gas methane
Decadal growth rate of methane in the atmosphere varied dramatically over the past 30 yeas with three distinct periods of slowed (1988-1998), quasi-stationary (1999-2006) and renewed (2007-2016) phases. An inverse analysis with atmospheric chemistry transport modeling explained these variations consistently. While emissions from oil and gas exploitation and natural climate events caused the slowed growth and the temporary pause, those from coal mining in China and livestock farming in the tropics drove the renewed growth.

Radioactive elements may be crucial to the habitability of rocky planets
The amount of long-lived radioactive elements incorporated into a rocky planet as it forms may be a crucial factor in determining its future habitability. That's because internal heating from the radioactive decay of the heavy elements thorium and uranium drives plate tectonics and may be necessary for the planet to generate a magnetic field. Earth's magnetic field protects the planet from solar winds and cosmic rays. (2020-11-10)

Crystals reveal the danger of sleeping volcanoes
Most active volcanoes on Earth are dormant and are normally not considered hazardous. A team of volcanologists from the University of Geneva has devised a technique that can predict their devastating potential. The scientists used zircon, a tiny crystal contained in volcanic rocks, to estimate the volume of magma that could be erupted once Nevado de Toluca volcano (Mexico) will wake up from its dormancy. Up to 350 km3 of magma are currently lying below. (2020-11-05)

Using a volcano's eruption 'memory' to forecast dangerous follow-on explosions
Stromboli, the 'lighthouse of the Mediterranean', is known for its low-energy but persistent explosive eruptions, behaviour that is known scientifically as Strombolian activity. Occasionally, however, more intense and sudden explosions occur, most recently in July and August last year (2019). These are known as 'Strombolian paroxysms'. During such events several of Stromboli's craters are active simultaneously and much greater volumes of pyroclastic materials are erupted than is usual for the volcano. (2020-10-28)

For the first time: Realistic simulation of plasma edge instabilities in tokamaks
