Last few decades were evident with an increase in frequency and intensity of bleaching events at different reef systems around the globe. The present work was carried out to disseminate the importance of atmospheric variables in inducing bleaching and coral reef degradation at Lakshadweep system. SST, UVR, cloud fraction and water vapor content was obtained from MODIS aqua and TOMS and interpreted with stress response to identify their influence in coral bleaching at Kavaratti and Agatti islands during 2010 and 2011. Results indicates that in Lakshadweep reef system water vapor positive feedback do have more influence in causing coral bleaching when compared with previously established cloud shading theory. This study is also an evidence for the integrated influence of stressors in causing bleaching when compared to the influence of single parameter alone.

*2016 Journal Impact Factor was established by dividing the number of articles published in 2014 and 2015 with the number of times they are cited in 2016 based on Google Scholar, Google Search and the Microsoft Academic Search. If ‘A’ is the total number of articles published in 2014 and 2015, and ‘B’ is the number of times these articles were cited in indexed publications during 2016 then, journal impact factor = A/B.
