150 words-What was the attitude of the Medieval/Early Renaissance church toward the use of musical instruments? Why did they feel this way?
er vapor, for instance, a very big component of greenhouse gases and an important player in enhancing the surface warming (Solomon et al. 2010), increases as the atmosphere heats up. This implicates that the possibility of precipitation and clouds, at least in the Northern Hemisphere, increases too. Hence frequent clouds and precipitation are among the most revelatory symptoms of climate change (NASA 2018b). The increased release of carbon dioxide into the atmosphere is mainly caused by anthropogenic activities like deforestation and especially burning fossil fuels. The CO2 adds up to natural emissions like respiration of volcano eruptions. These emissions have increased by more than 30% in the last century. As Figure 1 illustrates and as the Keeling Project on Mauna Loa, Hawaii, proved, the atmospheric carbon dioxide level has risen from an all-time average of 280 to 400 parts per million in just about 70 years. Even though its share in the greenhouse-gas-mix is relatively small, it is considered as the main booster to climate change (Reynolds et al. 2010). Figure 1: Atmospheric carbon dioxide level over the millenniums (NASA 2018c) Methane is a hydrocarbon gas which is an even more active heat-trapping gas than carbon dioxide. However, it occurs rarer in the atmosphere. It is produced naturally, for example through ruminant digestion and through the use of manure of domestic livestock (Grainger, Beauchemin 2011) and the decomposition of wastes in landfills. Its emission can also have anthropogenic causes like agriculture and rice cultivation (Yan et al. 2009). Another one of the main components is nitrous oxide. It is emitted during soil cultivation activities as well as fossil fuel combustion and biomass burning (NASA 2018b). The last main components are chlorofluorocarbons, which are solely used in an industrious way like for the cooling systems of fridges (NASA 2018b). However, their major share in the destruction of the ozone layer has long been discovered and their production has been cut down by international agreement. The amount of the before mentioned gases in the atmosphere has been rising now since the start of industrialization, making them with 100% certainty one of the major shareholders to the enhancement of the greenhouse effect (Chuvieco 2008). Their increase is a concrete objection to the fulfilment of the mitigation goal. 3 Expression of global climate change and possible surveillance methods>GET ANSWER
