TRINIDAD AND TOBAGO

3. Climate encompasses the statistics of temperature, humidity,
atmospheric pressure, wind, rainfall, atmospheric particle count and
Other meteorological elemental measurements in a given region
over long periods. Climate can be contrasted to weather, which is the
present condition of these elements and their variations over
shorter periods.

4. Climate change is a significant and lasting change in the statistical
distribution of weather patterns over periods ranging from
decades to millions of years. It may be a change in average
weather conditions or the distribution of events around that
average (e.g., more or fewer extreme weather events).
Climate change may be limited to a specific region or may occur
across the whole earth.
