Belize's Future: Global Warming's Impact Explored

Belize is highly vulnerable to the effects of global warming. As a small state situated on the Caribbean Sea, it is already facing hurricanes, flooding, sea level rise, coastal erosion, coral bleaching, and droughts, with impacts likely to intensify given expected increases in weather volatility and sea temperature. Sea temperatures are rising every year, resulting in coral bleaching and reduced fish catch, both of which significantly impact local livelihoods. Storms are becoming more intense and frequent, disrupting economic activities and severely impacting the lives of local communities.

Rising sea levels

Increased Flooding and Coastal Erosion

Belize's low-lying geography exacerbates the effects of rising sea levels, making the country more prone to flooding. Coastal areas are particularly vulnerable, with higher sea levels coinciding with more dangerous hurricanes and typhoons that move slowly and drop more rain. This combination of factors contributes to powerful storm surges that can cause devastating damage by stripping away everything in their path. As sea levels continue to rise, the frequency and severity of flooding events are expected to increase, forcing people to migrate to higher ground and disrupting basic services such as internet access.

Damage to the Belize Barrier Reef Reserve System

The Belize Barrier Reef Reserve System, a UNESCO World Heritage Site, is facing multiple impacts of climate change, including rising sea levels. The increase in sea levels, coupled with warmer temperatures and ocean acidification, poses a severe threat to the rich diversity of marine life that depends on this ecosystem. Rising sea levels can also lead to coastal erosion, further damaging the reef system and the livelihoods of the local communities that depend on it.

Coral Bleaching

Coral bleaching is one of the most serious consequences of rising sea temperatures and ocean acidification. It has already caused long-term damage to coral reefs worldwide, including those in Belize. The Belize Barrier Reef Reserve System is highly vulnerable to the physiological impacts of coral bleaching, which can disrupt the entire reef complex and the species that depend on it.

Loss of Habitat for Wildlife

As sea levels rise, coastal habitats are at risk of destructive erosion, wetland flooding, and contamination of aquifers and agricultural soils with saltwater. This loss of habitat can have far-reaching consequences for fish, birds, and plant species, as well as threatened species such as marine turtles, manatees, and the American crocodile, which depend on the reef system for survival.

Economic Impacts

Coral bleaching

Coral reefs, often called the rainforests of the ocean, are home to over a quarter of all marine life on Earth. They are incredibly important for the biodiversity of the ocean and the health of the planet. However, they are extremely vulnerable to the effects of global warming, and the coral reefs in Belize are no exception.

The Mesoamerican Barrier Reef, located between the Yucatan Peninsula in Mexico and Belize, holds a fragile coral reef system. Due to elevated temperatures caused by climate change, much of the reef environments have been transformed from vibrant to dull as massive coral bleaching has devastated the reef's wildlife. According to Zoe Dagan, a dive master at Glover's reef and coral reef educator, the bleaching events tend to be more extreme and last longer, which can be very harmful to the reefs.

The effects of coral bleaching are devastating. When coral is stressed by high temperatures, it expels its symbiotic algae, causing it to lose its brilliant colour and source of nutrients. Without algae to sustain them, the coral starves and can become vulnerable to disease and death. In addition, bleached coral has a compromised immune system, making it susceptible to different types of diseases. If temperatures remain high, the coral can die.

In 1998, Belize lost nearly half of its reef, a World Heritage Site, when global warming and the "El Nino" weather phenomenon combined to create the highest sea temperatures ever recorded worldwide. This event caused severe bleaching and mass mortality of corals on lagoonal reefs in Belize, and the first collapse of a coral population in the Caribbean. The effects of this bleaching event were long-lasting, and some scientists warn that the reef is likely to die if temperatures continue to rise.

More frequent and intense storms

Belize is highly vulnerable to the impacts of climate change, and storms are becoming more frequent and intense, with the 2020 Atlantic hurricane season seeing a record 30 named storms. These storms have disrupted economic activities and severely impacted the lives of local communities. Belize's low-lying terrain exacerbates the effects of flooding and sea-level rise, and the country is also at risk of extreme temperature events.

The Belize Barrier Reef Reserve System, the largest reef complex in the Atlantic-Caribbean region, is threatened by rising sea levels, increasing sea temperatures, and coral bleaching. The Resilient Reefs Initiative is working to build Belize's resilience by harnessing community knowledge, diversifying livelihoods, and balancing conservation with commercial and local use of the reef.

The government of Belize has implemented the five-year Marine Conservation and Climate Adaptation Project (MCCAP) to strengthen the climate resilience of the Belize barrier reef. The project has taken a multifaceted approach by helping coastal communities adapt to a changing climate, increasing protection and restoration efforts, and building public awareness about climate change.

The impacts of more frequent and intense storms on Belize are expected to be severe, and the country is ranked 8th out of 167 countries for climate risk.

Extreme temperature events

Belize is highly vulnerable to natural disasters and climate change. The country is already facing threats such as hurricanes, flooding, sea level rise, and extreme temperature events. Its low-lying terrain exacerbates the impacts of flooding and sea level rise, making it particularly susceptible to these events.

The Natural Disaster Hotspot study by the World Bank ranked Belize 61st out of 167 countries for relative mortality risk from multiple hazards, including extreme temperature events. This ranking underscores the significant threat that climate change poses to Belize and its population.

The impacts of extreme temperature events are expected to intensify with the projected increases in weather volatility and sea temperature rise. Warmer air temperatures can also lead to more moisture in the air, increasing the potential for heavier precipitation and more frequent flooding. This combination of extreme heat and flooding can have devastating effects on Belize's infrastructure, ecosystems, and communities.

To build resilience and adapt to these changes, Belize has been actively engaged in policymaking and development planning. The country has recognized the importance of resilience-building and has collaborated with organizations like the IMF and World Bank to understand and manage the economic impacts of climate change. Additionally, initiatives like the Resilient Reefs Initiative focus on harnessing community knowledge, diversifying livelihoods, and balancing conservation with commercial and local use of natural resources. These efforts aim to safeguard the country's ecosystems and communities from the adverse effects of extreme temperature events and other climate-related hazards.

Coastal erosion

Belize is highly vulnerable to the impacts of climate change, and coastal erosion is one of the most significant threats facing the country. Here is an overview of how global warming can exacerbate coastal erosion in Belize and its potential consequences:

Paragraph 1: Understanding Coastal Erosion

Paragraph 2: Impact of Global Warming on Coastal Erosion in Belize

The combination of rising sea levels and more frequent and intense storms due to global warming poses a significant threat to Belize's coastline. The country has already experienced coastal erosion along its shores, with events becoming more common as climate change impacts continue to grow. For example, the village of Hopkins in Belize experienced an erosion event along its 5.5-kilometre beach shoreline, resulting in the loss of 20 feet of shoreline. This event caused alarm among residents, who were concerned about the potential impact on their lives and the local economy, which relies heavily on tourism.

Paragraph 3: Factors Exacerbating Coastal Erosion in Belize

Several factors related to global warming exacerbate coastal erosion in Belize. One significant factor is the rise in sea surface temperature due to increased greenhouse gas emissions, which contributes to coral bleaching and the subsequent death of coral reefs. Belize has lost a significant portion of its coral reefs, which act as natural barriers that protect the coastline from erosion. Additionally, agricultural practices, such as diverting river water for irrigation, have reduced the amount of sediment reaching the coast, making it more vulnerable to erosion.

Paragraph 4: Consequences of Coastal Erosion in Belize

The consequences of coastal erosion in Belize are far-reaching and impact various aspects of society. One of the most direct impacts is the loss of properties and infrastructure located along the coastline. In Monkey River Village, for instance, coastal erosion has led to the loss of homes, streets, and recreational spaces. Additionally, coastal erosion threatens sacred sites, such as burial grounds, which are traditionally located close to the sea. The loss of these sites can have profound cultural and spiritual implications for the community.

Paragraph 5: Social and Economic Impacts

Paragraph 6: Mitigation and Adaptation

Belize has taken steps to address coastal erosion, such as constructing temporary sea defences. However, the effectiveness of these measures may be limited, and more comprehensive approaches are needed. One strategy is the protection and restoration of coastal wetlands, such as mangrove ecosystems, which act as natural buffers against erosion and storms. Additionally, local collective action and collaboration between communities, journalists, researchers, and local NGOs are crucial for advocating for protection and adaptation measures.
