Weather intensity – A force to be reckoned with


In Trinidad and Tobago, we are fortunate to be located in the Southern Caribbean just below the equator (Latitude: 10oN, Longitude: 61oW). When storms form in the Atlantic Ocean they rotate in a clockwise direction which projects the storms north-westerly, hence we are usually spared from bad weather. However, recently we have been experiencing intense weather conditions that were seemingly not there before. These once rare occurrences are becoming more frequent.

Why are we experiencing this weather?

Let us discuss the role that Climate Change has on the increasing weather intensity. Climate Change refers to the abnormalities that occur within our normal climate. For example, in Trinidad and Tobago, we have two seasons, the dry season and the wet season. This year we have had an extremely hot dry season, and we are currently experiencing torrential rains in our wet season. We have seen reports of rooves blowing away, trees falling, landslides, and much more throughout the length and breadth of the country. The now warmer waters of the Atlantic fuels more violent storms. It also means that there are storms more frequently.

After looking at the news on the night of September 3rd, 2021, a counselor from Cumuto brought up an important point about deforestation. The trees in forested areas like Cumuto once was, play a crucial role in breaking the wind shear. This protects us from facing the full brunt of the force of the wind. Not only is deforestation bad in terms of the wind shear but it also increases the surface runoff since there is less open soil and trees to soak up excess water. This results in flooding across numerous parts of Trinidad and Tobago. Our constantly changing environment alters the way that weather affects us, not just in terms of rainfall, but drought and increased temperature.

Additionally, we have been experiencing drastic weather changes. One minute we have scorching sunshine and in the blink of an eye the weather is completely changed. This is not a regular occurrence, but it is the weather we have been experiencing for the past two weeks. All these changes can be attributed to climate change.

Manatees in Trinidad and Tobago

Image
What are Manatees? Manatees, though they live in water, are classified as mammals because they come up to the surface every three to five minutes to get oxygen through their nostrils. In the Caribbean, we have the West Indian Manatee (Latin Name: Trichechus Manatus), also known as the ‘Sea Cow’. These gentle giants can grow up to 13 feet long and weigh up to 1200 pounds. Their diet consists of seagrasses and small invertebrates, consuming up to 15% of their body weight in vegetation. It is believed that the lack of predators in Trinidad and Tobago allows our Manatees to live up to sixty (60) years. Figure 1: showing a manatee floating (WNW Press Release 2021) What is the Status of our Manatees? In Trinidad, the Nariva Swamp is the most well-known habitat for manatees. However, based on an evaluation by UNEP/CEP in 1995, they determined that the manatee population consisted of twenty-five (25) to thirty (30) individuals in total. At that time the trend was that the population was de

Deforestation in Trinidad and Tobago

What is deforestation in Trinidad and Tobago? Deforestation is defined as the removal of trees from forested areas across the world. Locally, we have three main forested areas: the Northern range, Central Range in Trinidad, and the Main Ridge in Tobago. It is important to mention that South Trinidad is also largely forested especially in and around the Trinity Hills. These forested areas are constantly under attack by legal and illegal deforestation. Figure 1: showing deforestation in Trinidad (Loop News 2021) Deforestation in Trinidad and Tobago Firstly, not all deforestation is illegal. Companies that require space for infrastructural development can apply to the Environmental Management Authority (EMA) for approval on the project. The EMA can determine the impact that the project would cause on the environment based on the details of the venture. Lumber companies also need to apply for a license before they teardown trees from any area. However, a large portion of the trees

The East Coast Terror: Sargassum Seaweed

Image
  What is Sargassum Seaweed? Sargassum, also called gulfweed or sea holly, is a type of large, brown seaweed that floats on the surface of the ocean. Unlike many other types of seaweed, it never attaches to the seafloor. This type of seaweed is very abundant in the Atlantic Ocean from January to May (the Dry Season). It almost looks like a moving island, due to the large mats the seaweed forms in the ocean. It is deposited along the coastlines of Trinidad and Tobago. Figure 1: showing Sargassum mats in a Bay in Trinidad and Tobago (TEMA 2022) Where does the Sargassum come from? Sargassum originates from two main sources, the Sargasso Sea, located in the Northern Atlantic Ocean, and the Great Atlantic Sargassum Belt. The Atlantic Current is responsible for the movement of Sargassum and the deposits that are made along the West African Coast, the Eastern South American Coast, and throughout the Lesser Antilles.
