This has been supplemented by continuous erosion by sea towards the land. Global warming refers to the long-term rise in the average temperature of the Earth's climate system.It is a major aspect of climate change, and has been demonstrated by the instrumental temperature record which shows global warming of around 1 °C since the pre-industrial period, although the bulk of this (0.9 °C) has occurred since 1970. To understand what this means for humanity, it is necessary to understand what global warming is, how scientists know it's happening, and how they predict future climate. h�b```�W���B ��ea�h8�p��)P��b�1ǂ��,�� v�e��X�H;��c �ǖ@ 磏�g���"=+b-gk�+U���rI_s�Ԫ �m�L/O�u�<9FP�J�s�J�+���-p�7\�����3P��%��u��c-qɷ�#�쭑N��Z��^v���p��9�~�k��7O}?xw��s�� �\��g�Y������k�v|ȝ~�(a�7�F��� browser may not display or print as intended.

However, global warming, and with it climate change and … In fact, global warming has already begun, as earth’s temperature has risen between 0.4 and 0.8°C in the l ast 100 years. Changes in sea level would alter flooding patterns and the structure and areal extent of mangroves. Mangroves are tropical/subtropical communities of primarily tree species that grow in the intertidal zone. ߜ��: �r�==���-�#=�u2�v>*~�&KP�U�z��V��>d囷����W/G��j�.G���G`��͘��X=��U]�T�o~��;:B��X!\n[�V�/��݇Ua�(��� Mg��nYHU��g����W�� Widespread destruction of mangroves along the coasts results in economic damages of $6 – 42 billion every year, says a report titled “The Importance of Mangroves: A Call to Action”, released by the United Nations Environment Programme on Monday. 1472 0 obj <>stream �J0$c�-p3a�������u5���T7��O�ۧ�����|s��|���j�x�g�zZ�V�6��� Topic: Changes in critical geographical features (including waterbodies and ice-caps) and in flora and fauna and the effects of such changes 1) Discuss the significance of mangroves and the impact of climate change on them.

Therefore global warming will cause the development of this type of disease to become widespread and have an impact on humans. More specifically, changes to near-surface air temperatures will likely influence ecosystem functioning and thus the biodiversity of plants, animals, and other forms of life.The current geographic ranges of plant and animal species have been established by adaptation to long-term seasonal climate patterns.

The destruction of mangrove forests doesn’t just present a danger to the creatures that thrive within their ecosystems. the documents to your computer and open them with Adobe Reader. Beginning around the late 1980s, as evidence grew demonstrating global warming, a growing body of research has explored, and attempted to predict, how mangroves around the world, including in the The existence of mangrove peat deposits worldwide attests to past episodes of local and regional extinction, primarily in response to abrupt, rapid rises in sea level. In many countries with mangroves, much of the human population resides in the coastal zone, and their activities often negatively impact the integrity of mangrove forests. Causes of Depletion of mangroves Sea level rise and coastal erosion Due to global warming, the sea levels are continuously rising. These tidal forests are important coastal ecosystems that are valued for a variety of ecological and societal goods and services. For best results viewing and printing PDF documents, it is recommended that you download Global warming may promote expansion of mangrove forests to higher latitudes and accelerate sea-level rise through melting of polar ice or steric expansion of oceans. In the same way, where the land grows conifers and the like, the country was said to have one of the world’s largest mangrove forest. Elevated CO2 concentration may increase mangrove growth by stimulating photosynthesis or improving water use efficiency, but the consequences of this growth enhancement for the ecosystem are unknown. ��� These distinctive trees also help reduce global warming because their rich, waterlogged soil can absorb and store a great deal of carbon. [63] [64] Scientists realized over 30 years ago the ocean was a key fingerprint of human impact on climate change and "the best opportunity for major improvement in our understanding of climate sensitivity is probably monitoring of internal ocean temperature". The surface temperature of the earth is more than 0.74 degree Celsius higher than what it was 150 years ago and is expected to rise by a larger number in the next century. (Retd.) Global Warming and its Major effects on Environment and Human Health The “natural” greenhouse effect has been part of the basis of life on Earth since the early atmosphere formed.

Climate change may also alter rainfall patterns, which would in turn change local salinity regimes and competitive interactions of mangroves with other wetland species.
