Could Thermal Oceanic Hotspot Increase Climate Changes Activities in North Tropical Atlantic: Example of the 2005 Caribbean Coral Bleaching Hotspot and Hurricane Katrina Interaction
ثبت نشده
چکیده
This paper reviews recent studies and particularly the effects of Climate Change in the North Tropical Atlantic by studying atmospheric conditions that prevailed in 2005 ; Coral Bleaching HotSpot and Hurricane Katrina. In the aim to better understand and estimate the impact of the physical phenomenon, i.e. Thermal Oceanic HotSpot (TOHS), isotopic studies of δO and δC on marine animals from Guadeloupe (French Caribbean Island) were carried out. Recorded measures show Sea Surface Temperature (SST) up to 35°C in August which is much higher than data recorded by NOAA satellites 32°C. After having reviewed the process that led to the creation of Hurricane Katrina which hit New Orleans in August 29, 2005, it will be shown that the climatic conditions in the Caribbean from August to October 2005 have influenced Katrina evolution. This TOHS is a combined effect of various phenomenon which represent an additional factor to estimate future climate changes. Keywords—Climate Change, Thermal Ocean HotSpot, Isotope, Hurricane, Connection, Uncertainty, Sea, Science.

Model-based assessment of the role of human-induced climate change in the 2005 Caribbean coral bleaching event.
Episodes of mass coral bleaching around the world in recent decades have been attributed to periods of anomalously warm ocean temperatures. In 2005, the sea surface temperature (SST) anomaly in the tropical North Atlantic that may have contributed to the strong hurricane season caused widespread coral bleaching in the Eastern Caribbean. Here, we use two global climate models to evaluate the con...
متن کاملHurricanes and coral bleaching linked to changes in coral recruitment in Tobago.
Knowledge of coral recruitment patterns helps us understand how reefs react following major disturbances and provides us with an early warning system for predicting future reef health problems. We have reconstructed and interpreted historical and modern-day recruitment patterns, using a combination of growth modelling and in situ recruitment experiments, in order to understand how hurricanes, s...
متن کاملCoral reef bleaching and global climate change: can corals survive the next century?
C oral reef ecosystems are threatened on a worldwide basis, with overfishing, diseases, eutrophication, hurricanes, overpopulation, and global climate change all contributing to recent declines in reef-forming corals or phase shifts in community structure on time scales not observed previously (1–3). These changes are in contrast to recent periods of long-term stability in coral reef communitie...

Changes in some weather and climate extremes are attributable to human-induced emissions of greenhouse gases. Human-induced warming has likely caused much of the average temperature increase in North America • over the past 50 years. This affects changes in temperature extremes. Heavy precipitation events averaged over North America have increased over the past 50 years, • consistent with the o...
متن کاملCoral bleaching and disease should not be underestimated as causes of Caribbean coral reef decline.
In his recent paper 'A clear human footprint in the coral reefs of the Caribbean', Mora (2008) identifies the drivers of change in Caribbean coral reef communities based on the results of comprehensive analysis. Caution is warranted in accepting some of his major conclusions because, as he himself states, the analysis is a 'snapshot of the potential drivers of coral reef change' and because som...
