Velazco-Domínguez, MS Puerto Rico Department of Natural and Environmental Resources Ernesto Weil, PhD Dept. Australian and international research has shown that an increase in average global temperatures of just 1°C above the preindustrial period will cause coral … The production of limestone-like calcium carbonate is high enough in many warm-water coral reefs to establish carbonate structures. External factors.Externally, there is considerable variation in the environmental conditions experienced by coral colonies.This variation creates critical differences in exposure to heat, light or other stressors, leading to many of the patterns seen in bleaching responses. The Coral Reef Temperature Anomaly Database (CoRTAD) is an annually updated, long-term, high resolution collection of weekly averaged sea surface temperature (SST) and related thermal stress metrics derived from the 4 km AVHRR Pathfinder Project. You can download the paper by clicking the button above. Coral reefs are very sensitive to light and temperature. Climate change is making ocean heat waves worse—a reality that increases the chances for mass bleaching and puts young coral in jeopardy. too much light and heat will cause photosystem 2 of the zooks to get damaged, this means that the light reaction of photosynthisis is occuring and creating energy but this energy has no where to go and builds up in the zooks, this energy will then need somewhere to go, this somewhere comes in the form of the terminal electron acepter oxygen. In addition to discussing the impact of climate change and coral bleaching on reef ecosystems, panelists brainstormed ways to better reach both the public and policymakers.
