近几十年来，在全球变暖背景下，季节性极端降水事件的发生频率与强度日趋增加，亚洲季风区成为受其影响最大的地区之一。深入研究季风区降水的季节分配和变化规律，对于我国应对气候变化与可持续发展策略的制定与实施，具有至关重要的意义。然而，已有地质记录由于测年精度及代用指标分辨率的问题，难以揭示历史时期降雨的季节性变化。
More intense and frequent thunderstorms linked to global climate variability

More than half of the structures in the contiguous United States are exposed to potentially devastating natural hazards -- such as floods, tornadoes and wildfires -- according to a new study in the AG...
Asymmetry in CO2 emissions and removals could skew climate targets
carbon dioxide emissions climate targets carbon dioxide removals
<
2021/8/4
Changes in climate resulting from carbon dioxide (CO2) emissions into the Earth's atmosphere are not equal to the climate changes from deliberate CO2 removals -- and assuming such a balance could lead...
