The dark future of three decades after climate change

The dark future of three decades after climate change

On November 12, the world was celebrating the 50th anniversary of a cyclone. The typhoon claimed an estimated 3 million to 5 million lives. It was the deadliest tropical cyclone and the deadliest natural disaster ever recorded.

The catastrophic effects of the catastrophe and the weakness of the then government made it so politicized that it eventually had a direct impact on Bangladesh's freedom struggle. Finally, in 1971, Bangladesh seceded from Pakistan. But 50 years later, some countries in the world are at greater risk of cyclones, one of which is Fiji.

On November 7, Fiji's Prime Minister Frank Bainimarama became the first world leader to congratulate Biden on his victory in the US presidential election. "Congratulations Joe Biden," he tweeted. The time has come for us to work together to protect our planet and improve the global economy. "

"The rising tropical cyclone due to climate change poses a major threat to Fiji's development," said Prime Minister Bainimarama.

When Cyclone Winston hit Fiji on February 20, 2016. Which was considered the most severe cyclone recorded in the Southern Hemisphere. The cyclone killed 44 people and destroyed 40,000 homes. As many as 350,000 people were affected by the cyclone. A 60-day state of emergency was declared in the affected area and the damage was estimated at 1.5 billion US dollars.

Why are cyclones so dangerous?

Tropical cyclones have killed an estimated 2.6 million people worldwide in the last 200 years alone. A hurricane is a type of coastal flood that develops through a low-pressure system, such as a cyclone.

The intensity of the cyclone is increasing due to the hot air coming into the sea. Due to which the sea level also rises. According to studies by various organizations studying the effects of climate change, sea levels are expected to rise by 20 to 30 centimeters by 2050 compared to 2000. This has led to an increase in the risk of cyclonic storms, especially in small island nations.

Can we get information about cyclones from foreshadowing?

Due to the increasing use of satellite technology over the past 50 years, computing power and better forecasting models have dramatically improved cyclone forecasting. 20 years ago, the technology of forecasting up to 3 days was developed. Today, five-day forecasting technology has been developed.

But despite this revolution in the development of cyclone forecasting, the World Meteorological Organization (WMO) says the world is still weak in communicating the risks and effects of cyclones.

The WMO's 2020 State Weather Service report emphasizes the need for small island nations to adopt impact-based forecasts. Even for Fiji, some changes can be complicated. "The more we know what is important, the more we can act wisely," said Prime Minister Bainimarama.

Many small island nations have already identified the need to develop more effective early warning systems for cyclones as a matter of priority.

The Fiji government has released a post-disaster needs assessment report stating that it was not prepared for the intensity of the local typhoon at that time.
