Geochemical study of a 3.55 m long lake sediment core from the Badanital Lake (Garhwal Himalaya) reveals Late Holocene centennial-scale climatic changes. The ecosystem of the tectonically formed lake seems to be controlled by natural and anthropogenic factors. The imprints of four major global events, e.g. 4.2 ka event, Medieval Warm Period (MWP), Little Ice Age (LIA) and modern warming are obs...

Recent climatic changes have enhanced plant growth in northern mid-latitudes and high latitudes. However, a comprehensive analysis of the impact of global climatic changes on vegetation productivity has not before been expressed in the context of variable limiting factors to plant growth. We present a global investigation of vegetation responses to climatic changes by analyzing 18 years (1982 t...
