Nationalism is the ideological basis for the development of the modern nation-state. According to Leon Baradat, nationalism "calls on people to identify with the interests of their national group and to support the creation of a state - a nation-state - to support those interests."[1] It was an important factor in the development of Europe. In the 19th century, a wave of romantic nationalism swept the European continent, transforming its countries. Some newly formed countries, such as Germany and Italy were formed by uniting various regional states with a common "national identity". Others, such as Greece, Serbia, Poland, Romania and Bulgaria, were formed by uprisings against the Ottoman Empire and Russia. Nationalism was the ideological impetus that, over the century, transformed Europe. Rule by monarchies and foreign control of territory was replaced by self-determination and newly formed national governments. [2]
Climate oscillation or climate cycles are a recurring oscillation within the global or regional climates and their fluctuations produce varying climatic cells and pressures often occurring on an interannual and multi annular basis.
On a decadal and millennium timescales.Current examples of the ENSO, Pacific oscillation, Antarctica, and arctic oscillation. like ENSO is characterized by flooding and drought conditions and the distribution of extreme conditions in the form of heat and cold waves.
Other cycles like the Piora oscillation, Little ice age, medieval warm period, retreating of glaciers and warming of the planet. All these cycles move on earth from the equator to tropics to temperate to polar areas and the continuous warming and cooling periods have altered the rate of spreading of the seafloor and oceanic basin.
Present warming has drastically created a major change in the evolution of species causing extinction and quick decomposition of resources. The release of carbon and methane gases over these years have raised the greenhouse effect at alarming rates.
