Global Warming News Facts & Causes

Global Warming: News, Facts, Causes 

 

Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate.

There is great debate among many people, and sometimes in the news, on whether global warming is real (some call it a hoax). But climate scientists looking at the data and facts agree the planet is warming. While many view the effects of global warming to be more substantial and more rapidly occurring than others do, the scientific consensus on climatic changes related to global warming is that the average temperature of the Earth has risen between 0.4 and 0.8 °C over the past 100 years.

The increased volumes of carbon dioxide and other greenhouse gases released by the burning of fossil fuels, land clearing, agriculture, and other human activities, are believed to be the primary sources of the global warming that has occurred over the past 50 years. Scientists from the Intergovernmental Panel on Climate carrying out global warming research have recently predicted that average global temperatures could increase between 1.4 and 5.8 °C by the year 2100. Changes resulting from global warming may include rising sea levels due to the melting of the polar ice caps, as well as an increase in occurrence and severity of storms and other severe weather events.

Global warming is a phenomenon wherein there occurs a rise in the average temperature of the Earth’s atmosphere and water bodies since the late 19th century and is still an on-going process. Since the early 1900’s, Earth’s average surface temperature has rose by about 0.8 °C(1.4 °F), with almost two-thirds of this hike occurring since 1980. Proposed policy responses to this crisis include mitigation through emissions reduction, adaptation to its effects etc. Most of the countries in the world  are members of the  United Nations Framework Convention on Climate Change(UNFCCC)  whose sole objective is to prevent dangerous anthropocentric i.e., human-induced climate change. All of the party members have taken an oath to adopt a range of policies that work around reducing greenhouse gas emissions that are the sole reason for an increase in global. Currently efforts as of the early 21st century that  are mainly directed towards  reducing emissions seem to  be quite  inadequate to cope up with  the UNFCCC’s 2 °C target. Here are the top 10 causes for Global Warming.
