Global Warming and Climate Change

Global warming and climate change are often referred to interchangeably but there is a clear difference between the two. Global warming refers to increase in the temperature of Earth’s atmosphere due to the increase in fossil fuel emissions. Climate change refers to changing climate trends brought about by global warming. In other words, global warming causes climate change. While global warming describes the increase in the average temperature of the Earth, climate change is measured not only in terms of global changes in temperature, but also pertains to the change in strength and frequency of extreme weather events like...

Who was the first king of India

The great ruler Chandragupta Maurya, who founded Maurya Dynasty was indisputably the first king of India, as he not only won almost all the fragmented kingdoms in ancient India but also combined them into a large empire, boundaries of which were even extended to Afghanistan and towards the edge of Persia. Chandragupta Maurya was born around 340BC in Patliputra in Magadh, the region which is currently known as Bihar. He was only 20 years old when he founded Maurya Dynasty in Magadh with the help of great economist, scholar, philosopher and a learned Brahmin Chanakya. In fact, it was Chanakya who discovered Chandragupta Maurya in Vinjha Forest. Chanakya wanted to take revenge from Dhana Nand, the King of the then ruling Nanda Dynasty of Magadh. Chanakya was in the search of a young warrior who could help him eliminate Nanda Empire as the King Dhana Nand had once insulted him badly due to his ugly looks. On his orders, the soldiers of Dhana Nand had even forcefully thrown Chanakya out of his assembly. To fulfil his aim, Chanakya mentored and trained Chandragupta Maurya in different war skills. Simultaneously he also taught him humanities, crafts and all the political lessons required for becoming a powerful ruler. Later in the year 322 BC, Chandragupta Maurya successfully raised a strong army with the help of Chanakya and eliminated the empire of Dhana Nand and...

Know Who All Ruled India

Since the ancient time, India has remained under international spotlight, due to its immense wealth, spices, gold and an enormous expanse of natural resources, that’s why India was known as Golden Bird or Sone Ki Chidiya at one point of time. And to exploit its seamless wealth the country has been time and again invaded and ruled by numerous dynasties which include Sakas, Kushanas, Huns, Afghans, Turks, Khiljis, Lodhis and Mughals to the Britishers. Even, Alexander- the great ruler of ancient Greek kingdom also voyaged across several miles along with a huge army of Yavans in 326BC to invade India. However, his impressive winning streak finally met with an unfortunate end at the Hydaspas River where the most powerful King Porus of Paurava Kingdom (spanned across the current Punjab region) engaged him in a bloody battle and pushed him back. Overall, if we take a peek into the vast history of the rulers of India, we observe that India has witnessed the rule of several smaller kingdoms, while the power centres, mostly remained divided among the rulers of Magadha and Southern India. The bringing together of smaller states and kingdoms spanning from Himalayan region to Indian ocean, into one unified country was made possible only during the era of British rule. Finally, the British rule in India also ended in the year 1947 after nearly 200 years of Indian...

Global Warming

Due to global warming, the temperature of the Earth is continuously rising. There are tremendous changes in the climate with natural calamities striking us too often. The rise in sea level, changes in weather, melting of glaciers, decrease in forests, destruction of many types of organisms and vegetative species, increase in various diseases, etc are seen in all parts of the world. In fact, global warming is a major issue related to the existence of mankind. That’s why everyone should know about it and take steps to counter the threat posed by it. What is Global Warming? Global warming means continuous rise in Earth’s average surface or environmental temperature due to greenhouse effect.  Now what’s greenhouse effect? The Earth’s atmosphere is composed of nitrogen, oxygen, etc which is responsible for maintaining average temperature for life on Earth at 16 degree Celsius. When the sun rays collide with the Earth’s surface, most of the energy is absorbed by greenhouse gases such as carbon dioxide, methane, nitrous oxide, sulphur dioxide, carbon monoxide, while a part of the solar radiation called infrared radiation returns into space by means of clouds, snowflakes, and other reflective things. Reasons/Causes of Global Warming The most important reason for the increase in the temperature of our Earth is the continuous increase in the pollution, due to which the level of greenhouse gases is increasing, which is damaging the...
