Increased concentrations of GHG's above the naturally occurring level of concentration therefore lead to an enhanced Greenhouse Effect. It is a fact that the sun migrates annually between 23 o N and 23 o S, yet to answer the question, one must turn to the general circulation of the atmosphere to explain the apparent paradox. In addition one must also turn to the role water vapour plays in the transfer of heat. The production of precipitation in this matter must also be seen as the production of heat which ameliorates polar temperatures. Back to top Over the march of time, one may experience wet or dry summers, mild or cold winters, hurricane seasons that are either active or relatively quiet.
Scenarios described above are more in keeping with climate variability.
Climate change scenarios are longer term i.e. in the order of decades or centuries. However, with noted global warming, it is becoming increasingly evident that such changing periods are becoming shorter. It is claimed that with Global warming and Climate Change the Caribbean region will experience increased hurricane activity, with the increased likelihood of more intense storms. A major concern for the Caribbean must be any possible trend in intensity, frequency and tracks of Atlantic hurricanes. Climate models have not yet yielded consistent answers to the future of hurricanes.
