Global Warming Global warming is the gradual rise in the overall temperature of the Earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.

Causes of Global Warming: Natural causes Variations in the Earth’s orbit Variations in tilt of the Earth’s axis Variations in sunspot activity Changes in the amount of dust in the atmosphere Changes in the Earth’s ocean currents

Anthropogenic Causes:

Consequences:

Melting of glaciers

Number of death and Total loss of economic value

Inactivity and Clean Energy

Global Climate Change - Statistics & Facts In 2016, the earth’s surface temperature was around 0.94 Celsius degrees warmer than the 20th century average. In the last few years, global temperatures have been consistently among the hottest on record. The global anomaly in surface temperature might be the cause of an increase in sea level, a decrease in artic ice and the growing number of weather-related catastrophes, including storms, floods and droughts. The economic loss due to the 2012 drought in United States reached around 20 billion U.S. dollars, making it the country’s most costly drought in history. Between November 30 and December 11, 2015, Paris hosted the 21st session of the Conference of the Parties to the United Nations' Framework Conference on Climate Change. The objective of the annual conference was to tackle climate change, stabilize greenhouse gas concentrations in the atmosphere, and to reach a post-Kyoto Protocol agreement. The Kyoto Protocol was initially adopted in 1997 as an extension to the United Nations Framework Convention on Climate Change (UNFCCC).

Projected impacts of climate change in Mauritius ·        Decreasing trend of 8% in annual rainfall.  Utilizable water resources will decrease by up to 13% by 2050. ·        Increase in heavy precipitation events with increased risk of flash flood. ·        More frequent heat waves in summer.   ·        Increasing frequency of heat spells, giving rise to cardiovascular and pulmonary complications. ·        Increase in the number of intense tropical cyclones ·        Increase in duration of dry spell ·        Increase events of high energy waves (tidal surge) impacting the shores of Mauritius. ·        Heat stress will impact on productivity in the poultry and livestock sector ·        Propagation of vector-borne and infectious diseases as a result of higher temperature and recurrent floods. ·        Lengthening of the transmission period of important vector-borne diseases due to rise in temperature.  ·        Live corals to be reduced by 80-100% in the event of 3.28oC rise in temperature by the year 2100.  ·        Migratory shifts in tuna aggregations thereby disrupting the local seafood hub activities and other fish based industries and may result in conflict over the stock both at a national and international level. ·        Changes in fish stock distribution and fluctuations in abundance of conventionally fished and “new” species may disrupt existing allocation arrangements.
