Most scientists agree that sea temperature increases due to global climate change have already caused mass mortality of corals throughout the tropics over the last 5-10 years. Given the current climate change predictions from organisations like the Hadley Centre in the UK, it appears likely that increases in sea temperatures will cause the complete collapse of these ecosystems within only a few decades. These estimates may be too pessimistic, because corals are able to adapt to rising temperatures using a variety of mechanisms. However, at the same time coral diseases have become increasingly common, as they have in many other systems and groups of organisms. Several scientists have proposed that these increases in disease are linked to climate change and we aim here to test whether temperature stress increases a corals' susceptibility to disease by monitoring indicators of health, antimicrobial defences and bacterial community structure and function. There are other possible causes of the recorded increase in diseases, however, such as increased transport and transfer of micro-organisms via tourists or ships' ballast water, for example. It is therfore vital that we understand the disease process so that appropriate and effective measures can be used to improve the health of coral reefs.

大多数科学家都认为，过去 5-10 年来，全球气候变化导致的海水温度升高已经导致整个热带地区的珊瑚大量死亡。鉴于英国哈德利中心等组织目前对气候变化的预测，海水温度上升很可能会在短短几十年内导致这些生态系统完全崩溃。这些估计可能过于悲观，因为珊瑚能够通过多种机制适应不断上升的温度。然而，与此同时，珊瑚疾病变得越来越普遍，就像在许多其他系统和生物体群体中一样。一些科学家提出，疾病的增加与气候变化有关，我们的目标是通过监测健康指标、抗菌防御以​​及细菌群落结构和功能来测试温度压力是否会增加珊瑚对疾病的易感性。然而，造成疾病数量增加的还有其他可能的原因，例如微生物通过游客或船舶压载水的运输和转移增加。因此，我们了解疾病的过程至关重要，以便采取适当有效的措施来改善珊瑚礁的健康。
