Rise in Southeast Asia forest clearance increasing greenhouse gases
forest clearance greenhouse gases Southeast Asia
2021/8/3
Forest clearance in Southeast Asia is accelerating, leading to unprecedented increases in carbon emissions, according to new research. The findings show that forests are being cut down at increasingly...
Rising greenhouse gases pose continued threat to Arctic ozone layer
ozone loss greenhouse gases climate change
2021/8/4
A new study shows that extremely low winter temperatures high in the atmosphere over the Arctic are becoming more frequent and more extreme because of climate patterns associated with global warming. ...

Gases ancient Inland Northwest volcanic eruptions blocked out sun cooling planet
2017/10/25
The Pacific Northwest was home to one of the Earth’s largest known volcanic eruptions, a millennia-long spewing of sulfuric gas that blocked out the sun and cooled the planet, Washington State Univers...
Stellar parenting:Making new stars by 'adopting' stray cosmic gases
Stellar parenting Making new stars adopting stray cosmic gases
2016/2/22
Among the most striking objects in the universe are glittering, dense swarms of stars known as globular clusters. Astronomers had long thought globular clusters formed their millions of stars in bulk ...
ANOMALOUS CURRENT IN PERIODIC LORENTZ GASES WITH INFINITE HORIZON
PERIODIC LORENTZ GASES INFINITE HORIZON
2015/9/29
We study electrical current in two-dimensional periodic Lorentz gas in the presence of a weak homogeneous etric field.When the horizon is finite, i.e. the free flights between
colli...
Vapour-phase crystallisation of silica from SiF4-bearing volcanic gases
SiF4 vapour crystallisation silica degassing
2015/9/10
Thermodynamic modelling of magmatic gases shows that SiF4 may be an important F-bearing species at the high
pressures typical of magma reservoirs. Upon decompression during degassing, SiF4 will react...
Isotopically light carbon dioxide in nitrogen rich gases: the gas distribution pattern in the French Massif Central, the Eifel and the western Eger Rift
Eger Rift French Massif Central Eifel carbon dioxide gas fractionation isotope composition
2015/9/10
Based on characteristics of the distribution pattern of the western Eger Rift spring gases, a distribution pattern is
presented for the gases of the French Massif Central. The central parts of these ...
Chemical and isotopic composition of fumarolic gases at Iwate volcano, Japan, during and after seismic activity in 1998: implications for the modification of ascending volcanic gases
Volcanoes volcanic earthquakes expectations and volcanic gases seismic activity the concentration of hydrochloric acid
2015/8/27
In 1998, there were many volcanic earthquakes recorded at Iwate volcano, Japan. Although an eruption was anticipated, it never occurred. Fumarolic gases were sampled at the volcano on six occasions du...
Ionospheric trends in Southern Hemisphere stations due to the increasing greenhouse gases concentration

2015/8/14
The lower and middle atmosphere present long-term variations in temperature and other parameters linked to anthropogenic sources, such as the increase in greenhouse gases concentration since the start...
A new WRF-Chem treatment for studying regional-scale impacts of cloud processes on aerosol and trace gases in parameterized cumuli
regional-scale impacts new WRF-Chem treatment
2015/3/5
A new treatment of cloud effects on aerosol and
trace gases within parameterized shallow and deep convection, and aerosol effects on cloud droplet number, has been
implemented in the Weather Researc...
Landau damping of spin waves in trapped Boltzmann gases
Ultracold gas boltzmann spatial dependence
2014/12/20
A semiclassical method is used to study Landau damping of transverse pseudo-spin waves in harmonically trapped ultracold gases in the collisionless Boltzmann limit. In this approach, the time evolutio...
