The entire US state of Florida will be submerged in 5cm of water forever if this disaster is not prevented: The world 'wobbles'!

In just 1 day, 8.5 billion tons of ice poured into the sea!

Located in the Southeast region of the United States, Florida is the only state bordering both the Gulf of Mexico and the Atlantic Ocean at the same time, so it possesses a total coastline of 13,500km. With an area of ​​170,311 square kilometers, Florida is the 22nd largest state in the United States by area.

This southeastern state of the United States has a very different topographical feature: It is very flat, even low terrain - The lowest point is 8 meters below sea level. The highest point is near the Alabama border in Walton County, just 105 meters above sea level.

In the eyes of scientists, all these geographical features are very worrying. Why?

In a world that is increasingly warming due to climate change, the snow and ice are disintegrating massively. With a state with a coastline of nearly 14,000km plus low terrain, Florida has made Florida "very vulnerable" to rising sea levels (due to melting ice).

Statistics of scientists show that Greenland has experienced a major ice melt event during an Arctic heat wave, the amount of water ice could cover the entire state of Florida in 5cm of water.

2nd largest ice block crashed world

Specifically, according to the Danish Meteorological Institute, this is one of the most severe ice melting events of 2021 - the Greenland ice sheet has undergone a major meltdown due to a heatwave occurring in the Arctic region. .

The heatwave in northern Greenland saw temperatures rise more than 20 degrees Celsius above average compared to previous years in the same period.

On July 27, 201 alone, a huge amount of ice weighing up to 8.5 billion tons collapsed and melted into the ocean. That amount of ice lost on July 27 is said to be enough to flood the entire US state of Florida in 5cm of water!

This is not an approximate image. Because if the ice continues to melt like this, coastal cities and countries will suffer this terrible disaster.

The Greenland ice sheet is the world's second largest freshwater ice sheet, covering an area of ​​1.8 million square kilometers. Fortunately, the largest iceberg on the planet is still in Antarctica.

In the last week of July 2021, the total amount of ice in Greenland has lost up to 18.4 billion tons. Although the total amount of ice lost that week does not exceed the total amount of ice lost in one week of 2019, that part of the ice melt area is larger than the event two years ago.

The Danish researchers also reported that the current rate of ice melt is twice as high as normal in previous summers many years ago.

Melting events were recorded in 1990 but have accelerated since 2000. High volume melt loss in recent years has occurred four times faster than before 2000.

2019 alone saw 532 billion tons of ice collapse and then enter the oceans, thus resulting in a permanent 1.5 mm increase in global sea levels.

The Greenland ice melt event comes days after the Greenland government announced that it would suspend all oil and gas exploration and future plans due to environmental and climate change concerns.

Storms raging

The Arctic heatwave (which causes melting ice) is just one of many extreme/extreme climate events happening globally just this summer 2021, as temperatures reach new peaks on the west coast of Canada and the United States in July 2021, as well as in Siberia, where hundreds of wildfires have occurred in the region.

Many other parts of the world are still facing terrible floods. This pandemic has been, is and will have a wide-ranging impact.

This is the evidence of scientists.

1. Hundreds of millions of people could be hit by floods

At one point in 2020, a third of Bangladesh is underwater. Although seasonal flooding is not unusual in Bangladesh, a low-lying country, in recent years the frequency and intensity of irregular floods has increased and caused serious financial damage. property and human life.

Like Bangladesh, countries in East, Southeast and South Asia have had millions displaced and hundreds killed due to heavy rainfall and flooding. Models consistently predict that climate change in Asia will manifest into more intense floods and rainy seasons.

According to a recent study published in the Nature Portfolio Journal, over the past 20 years, at least 86 million people have relocated or relocated to high-risk areas (flood zones) - increasing the risk makes 20% of the world's population vulnerable to flooding [10 times higher than previous estimates].

Thus, about 290 million people will be directly affected by major floods and if this trajectory continues, more people will lose their homes, livelihoods and die from floods.

Using climate models from the World Resources Institute, the study also forecasts that between 2010 and 2030 it is likely that an additional 179 million people will be affected by the effects of flooding.

Some of the worst floods ever hit countries in the global south, including sub-Saharan Africa, South Asia and Southeast Asia. Flooding affects more people than any other environmental hazard. Flooding hinders sustainable development, scientists say.

2. South and Southeast Asia 'most vulnerable'

Low-lying and crowded cities in many South and Southeast Asian countries are most at risk, and the millions of people living there are particularly vulnerable. It is especially one of the most flood prone areas in the world. Floods frequently occur due to strong monsoons causing great damage to people's lives, property, crops and infrastructure.

This is the result of research by a team of scientists from the University of Arizona (USA), after using thousands of satellite images taken over nearly two decades, recording 913 major floods around the globe since 2015. 2000 to 2018.

The Asian Development Bank (ADB) offers a scenario: Climate change could reduce Southeast Asia's GDP by 11%, affecting key industries such as agriculture, tourism, and fishing. , health and labor productivity. Without technological progress, rice yields in Indonesia, the Philippines, Thailand and Vietnam could fall by nearly 50% by 2100 from 1990 levels.

Similar effects on key economic sectors are likely in South Asia. For example, in an average year, flood-related costs in Bangladesh are about US$175 million. However, in extreme cases, these costs can exceed $2 billion - This is the result of the 1998 flood when more than 70% of Bangladesh was under water.

Along with droughts in many parts of the world (especially in Africa), floods and melting ice have all left many parts of the world under water - in a world that is increasingly warming and climate change difficult. measure.
