Global warming is the long-term rise in the average temperature of the Earth’s climate system. The concern about the environment is always first priority. Environment and climate and related to each other, when some imbalance in environment occurs the effect is reflected by the climate. Many national and international policies have been framed to fight with the ailing environment and reduction in the rise of temperature. The main reason of the climate change is the Greenhouse gases with the major contribution of carbon dioxide. A recent study by British Antarctic Survey reveal: An iceberg twice the size of New York City is about to break off of Antarctica. A chasm (chasm 1 and chasm 2) and a crack (Halloween crack) on the Brunt Ice Shelf in Antarctica are creeping closer and closer to one another, and when the two finally meet, a slab of ice twice the size of New York City will break away and float out to sea. The two glacial flaws are about 2.5 miles apart, and it could take days or months for them to finally rendezvous. In October 2016, another crack called the Halloween crack quickly formed 17 kilometres north of the research station. It continues to extend east.
In general global warming is a matter of concern: it is neither in the first nor for last time. So, an agreement was initiated known as Paris agreement which deals with greenhouse-gas-emissions mitigation, adaptation, and finance, starting in the year 2020. The agreement›s language was negotiated by representatives of 196 state parties at the 21st Conference of the Parties of the UNFCCC (United Nations Framework Convention on Climate Change) in Le Bourget, near Paris, France, and adopted by consensus on 12 December 2015. As of February 2019, 195 UNFCCC members have signed the agreement, and 185 have become party to it. The Paris Agreement›s long-term goal is to keep the increase in global average temperature to well below 2 °C above pre-industrial levels; and to limit the increase to 1.5 °C, since this would substantially reduce the risks and effects of climate change. And , other protocols have been framed such as Kyoto Protocol and so on.
What causes the Greenhouse effect?
The main reasons of the Greenhouse effect are greenhouses gases (carbon dioxide and other gases), which result from the fossil fuel fired power plants and other industrial processing plants, and deforestation which in turn reflects from modernisation. Modernisation has a head on relation with the economy, and hence the relation with energy assets. The oil crisis in 1973 and 1979 has moved the intension of the nations to renewable assets, but the behaviour of mankind did not support it, as we cannot achieve the best outcomes and it also requires huge investment. Now , fossil fuel assets show a decline in reserves and the dramatic impact on the health of earth and atmosphere has fiercely changed the mind of modern society to renewable assets( with huge investment in R&D and adopting the protocols, policies, Acts).
