Atmospheric scientists fires resolve ice question climate models
2020/9/4
When fossil fuel or biomass burns, soot -- also known as black carbon -- fills the air. Black carbon is an important short-term climate driver because it absorbs solar energy and can affect the format...
Volcanic activity and changes in Earth's mantle were key to rise of atmospheric oxygen（图）
Volcanic activity changes Earth mantle were key rise atmospheric oxygen
2020/6/19
Oxygen first accumulated in the Earth's atmosphere about 2.4 billion years ago, during the Great Oxidation Event. A long-standing puzzle has been that geologic clues suggest early bacteria were photos...

2020/6/12
Atmospheric scientist Sonia Kreidenweis of Colorado State University and her colleagues have identified an atmospheric region unchanged by human-related activities. The National Science...
Scientists solve long-standing mystery:Why atmospheric carbon dioxide was lower during ice ages（图）
Scientists long-standing mystery atmospheric carbon dioxide lower during ice ages
2019/10/28
Since scientists first determined that atmospheric carbon dioxide was lower during ice ages than during warm phases, they have looked at why, theorizing that it may be a function of ocean circulation,...
Six million years ago, atmospheric shifts led to increased diversity of grassland mammals（图）
Six million years ago atmospheric shifts grassland mammals
2019/10/30
Six million years ago, grass-eating mammals became more diverse in South America. Shifts in tropical atmospheric circulation known as Hadley circulation led to changes in climate and vegetation, espec...
