ABSTRACT The damage which brought about global warming and climate change to heritage sites is more or less immutable. However, further deterioration could be slowed, if not stopped, with the patronization of green energy. Three sources of green energy, namely solar power, wind power, and hydropower were discussed in this research. Their indirect role in preserving heritage sites was examined and their cumulative effects on mitigating climate change were also cited. Results showed that the climate might have been continually changing for the past thousands of years. The effects of climate change and global warming on the arctic ice, carbon dioxide concentration, sea levels, global surface temperat...

ABSTRACT Global warming is predicted to strengthen marine plant-herbivore interactions. However, little is known about the effect of temperature on palatability and the associated chemical composition of marine macroalgae. To study the effects of physiological stress caused by the warm water temperatures and nutrient-poor conditions that occur during summer, we cultured the brown alga Sargassum yezoense at three different temperatures (16°C, 22°C, and 28°C) in both nutrient-enriched and non-enriched media. We then compared phlorotannin (i.e., defensive compounds) and nitrogen concentrations of S. yezoense as well as consumption rate by the sea urchin Hemicetrotus pulcherri...
