Definition
Climate change describes a change in the average conditions such as temperature and rainfall in a region over a long period of time.
History
NASA scientists have observed Earth’s surface is warming, and many of the warmest years on record have happened in the past 20 years. Nineteen of the 20 warmest years all have occurred since 2001, with the exception of 1998. The year 2016 ranks as the warmest on record.
Causes
scientists agree that Earth has been getting warmer in the past 50 to 100 years due to human activities.
Certain gases in Earth’s atmosphere block heat from escaping. This is called the greenhouse effect. These gases keep Earth warm like the glass in a greenhouse keeps plants warm.
Human activities — such as burning fuel to power factories, cars and buses — are changing the natural greenhouse. These changes cause the atmosphere to trap more heat than it used to, leading to a warmer Earth.
Greenhouse Effect
a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse consists of carbon dioxide (0.04%), nitrous oxide, methane and ozone are trace gases that account for almost one tenth of 1% of Earth's atmosphere and have an appreciable greenhouse effect. Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels.
Paris Agreement
The Paris Agreement is the first truly global commitment to fight the climate crisis. In 2015, 195 countries and the European Union signed on to a single, sweeping agreement that aims to keep global warming to well below 2°C (3.6°F)—and make every effort to go above 1.5°C (2.7°F).
UNFCCC
The Conference of the Parties or COP is the supreme decision-making body of the United Nations Framework Convention on Climate Change (UNFCCC). The UNFCCC came into force on the 21 March 1994 and today it has a near-universal membership with 197 countries that have ratified the convention. Its main objective is to “stabilize greenhouse gas concentrations at a level that would prevent dangerous human-induced (anthropogenic) interference with the climate system”
