Climate engineeringClimate engineering (also called geoengineering) is a term used for both carbon dioxide removal and solar radiation management, also called solar geoengineering, when applied at a planetary scale. However, they have very different geophysical characteristics which is why the Intergovernmental Panel on Climate Change no longer uses this overarching term. Carbon dioxide removal approaches are part of climate change mitigation. Solar geoengineering involves reflecting some sunlight (solar radiation) back to space.
Polar amplificationPolar amplification is the phenomenon that any change in the net radiation balance (for example greenhouse intensification) tends to produce a larger change in temperature near the poles than in the planetary average. This is commonly referred to as the ratio of polar warming to tropical warming. On a planet with an atmosphere that can restrict emission of longwave radiation to space (a greenhouse effect), surface temperatures will be warmer than a simple planetary equilibrium temperature calculation would predict.
Tibetic languagesThe Tibetic languages form a well-defined group of languages descended from Old Tibetan (7th to 9th centuries). According to Tournadre (2014), there are 50 languages, which split into over 200 dialects or could be grouped into 8 dialect continua. These languages are spoken in the Tibetan Plateau and in the Himalayas in Gilgit-Baltistan, Aksai Chin, Ladakh, Nepal, Himachal Pradesh, Uttarakhand, and Bhutan. Classical Tibetan is the major literary language, particularly for its use in Buddhist literature.
SawdustSawdust (or wood dust) is a by-product or waste product of woodworking operations such as sawing, sanding, milling, planing, and routing. It is composed of small chippings of wood. These operations can be performed by woodworking machinery, portable power tools or by use of hand tools. Wood dust is also the byproduct of certain animals, birds and insects which live in wood, such as the woodpecker and carpenter ant. In some manufacturing industries it can be a significant fire hazard and source of occupational dust exposure.
