Climate science is the study of relatively long-term weather conditions, typically spanning decades to centuries but extending to geological timescales. The discipline is primarily concerned with atmospheric properties – for example temperature and humidity – and patterns of circulation, as well as interactions with the ocean, the biosphere, and, over longer timescales, the geosphere.
The causes of symmetrical changes in climate between the Northern and Southern Hemisphere are poorly understood. A geological reconstruction of Patagonian glacial extent reveals that changes in Pacific-wide atmospheric circulation (linked to variations in Earth’s orbit and teleconnections between hemispheres) may have led to nearly synchronous global ice sheet evolution.
The response of ozone in the secondary ozone layer to energetic particle precipitation events leads to significant changes in ozone concentration globally due to induced residual circulation changes, suggest satellite-based observations and numerical modelling.
Data-driven detection of governing rules and trends in dynamics of nonautonomous systems usually requires a significant amount of measured data. The authors propose an operator-theoretic technique for identifying trends and persistent cycles using data from a single measured trajectory, relevant for the analysis of climate dynamics.
The first case in East Asia to challenge government climate policies will boost awareness of global warming and encourage further lawsuits in the region.
The inherent differences in epistemologies and research methods in electrical engineering and earth science hinder interdisciplinary collaboration. In the context of climate change, this divide affects the shift towards long-term sustainability in global energy systems, prompting dialogue between the disciplines to enable effective interdisciplinary collaborations.
Rich nations’ fixation on forests as climate offsets has resulted in the needs of those who live in or make a living from these resources being ignored. A broader view and more collaboration between disciplines is required.
