The Sea Level Rise May Be Irreversible
Every year we see the loss of coastal regions due to rising sea levels and erosion. In fact, by the end of this century, when the ice at the poles melts completely, sea levels may be up to 23 feet higher than they are today.
Climate change is known to be a major factor in the rise of sea levels globally. It is also becoming increasingly clear that this is not a problem we can ignore.
If we don’t take measures to stop it now, then it may be too late to stop it later.
The glaciers at the north and south poles are melting rapidly, and this has an impact on sea levels. The rising temperatures in the ocean caused by climate change cause the sea level to rise.
This, in turn, causes higher tides and leads to more erosion along coastlines. Coastal areas are also more vulnerable to storm surges, which can lead to more flooding and damage.
We’ve been hearing about climate change and its effects for decades now. There’s no denying that the changes in the Earth’s environment are real, and they’re happening faster than anyone predicted. Every year we see the loss of coastal regions due to rising sea levels and erosion.
What can we do? The seas are rising, but there is something we can do about it. By reducing our carbon emissions, we can reduce the amount of greenhouse gas that is released into the atmosphere.
This will slow down the rate at which the ice melts and help to keep our coastal regions from being flooded.
The World’s Coastlines Are Retreating
The map of the world has changed, and it’s continuing to change. Humans are killing our oceans, and the coastlines are retreating due to erosion.
Erosion is a natural process that can lead to significant changes in our landscape. It’s a naturally occurring process of the earth, but humans have sped up this process by interfering with nature.
The single most important fact to understand about coastal erosion is that it occurs on a human timescale. The coastline does not change overnight; it changes over decades and centuries. In other words: we are responsible for coastal erosion, and we can do something about it.
The loss of sand along beaches is natural and happens over time due to a combination of wave action, tides, currents, and storms.
However, human activities such as dredging or construction in coastal or marine areas can cause scarring of the sea bottom and increase the rate at which sand erodes.
Damming rivers can increase sedimentation in lakes, resulting in the filling of these water bodies. This can also cause sedimentation along the coasts and reduce rates of sediment transport downstream to estuaries and shorelines.
Beaches are naturally formed by erosion and deposition processes (the interaction between waves).
The removal of sand from beaches to replenish eroded beaches elsewhere can disrupt this process significantly and may lead to beach erosion in areas where sand has been removed.
Sea Level Rise Is a Problem We Have Now
We’ve been talking about climate change and global warming for what feels like forever, right? And it’s a bit overwhelming to devote so much attention to something that can seem remote or abstract when you’re busy with your life. But sea level rise is a problem we have now — and not in some distant future.
The impacts of climate change are getting closer, and we’re seeing them in our homes, businesses, and communities. Storm surges are sweeping away buildings and homes; flooding is damaging roads, bridges, railways and ports; wildfires are destroying our forests.
The seas will continue to grow for centuries. Sea levels won’t stop rising when we reach the climate tipping point; they will continue to rise for centuries.
This means that any actions we take now that affect sea levels won’t have an immediate effect — but they will influence future generations.
Over the past century, the global sea level rose by about 8ins. But scientists have seen an accelerating rate of rise since 1993. In actual fact, the rate of sea level rise has doubled since then. So, what’s behind this acceleration? The main cause is melting ice – and not just at the poles.
Most of this ice comes from glaciers and ice caps, which are melting because of global warming. This includes melting land ice on Greenland and Antarctica.
In the coming decades, hundreds of millions of people will be forced to flee their homes because of rising sea levels and climate change.
With nowhere else to go, many will head to cities. Already, half of all people live in urban areas, a proportion that is growing rapidly.
Rising Ocean Levels Also Can Make Storms Worse
When we hear of rising sea levels, the first thing that might come to our minds is how it is going to affect our beaches. But what you may not know is that rising sea level can also be attributed to more intense storms too.
It is the increase in the amount of moisture that adds fuel to the fire and greatly magnifies the amount of damage caused by the storm.
According to research, when it comes to intensifying tropical cyclones, sea level rise plays an important role in this process. These cyclones are well known as hurricanes in the Atlantic Ocean, typhoons in the Pacific Ocean, and cyclones in the Indian Ocean.
The increasing number of tropical storms and hurricanes has been a major concern in recent years. The latest estimates suggest that climate change may be making them stronger and more frequent than ever before.
How Does Climate Change Effect You?
While the long-term effect of climate change is uncertain, it’s clear that each day more people are experiencing more extreme weather conditions than ever before. It’s causing damage to homes and businesses, disrupting transportation, and even leading to public health issues. Climate change is already happening, and if it continues climate change will have an impact on almost everything in your life.
The problem with increasing ocean levels is that it increases the number of storm surges and coastal flooding during a storm. Storm surges are mainly driven by wind speed.
However, in areas where there are already high sea levels, it doesn’t take much to cause severe flooding.
Scientists also say that rising sea levels will also make storm surges from hurricanes worse as well as storms like Nor’easters or other winter storms that are driven by low-pressure systems along the east coast.
As sea levels rise over time, this phenomenon will only get worse, so expect stronger storms and higher death tolls as time goes on if we do not reverse this trend.
Sea Level Rise Could Mean More Damaging Tsunamis
Sea level rise linked to global climate change could be making devastating tsunamis more frequent, researchers warn. For the first time, scientists have related modern sea level rise to the frequency of tsunamis striking certain coastlines around the world.
In a study of the western Pacific, researchers found that when sea levels rose by as little as 10cms (four inches), the frequency of tsunamis increased by between 5-10%.
The researchers tracked the frequency of tsunamis striking coastlines in the Pacific Ocean, which is home to most of the world’s tsunami risk. They found that where sea levels are rising fastest, the frequency of damaging tsunamis is also increasing.
This is because a tsunami’s energy spreads out as it moves inland and higher ground rises more slowly than lower ground. Meaning the distance over which a tsunami’s energy spreads increases as it moves onto land.
This means that for any given wave height, a tsunami will have more destructive power if sea levels are rising.
The results also show that along parts of the coastlines studied, rising sea levels could offset much or all the benefits that come from building better defences against tsunamis.
This includes efforts to strengthen buildings against damage or working on early warning systems. The research was led by scientists at the National Oceanography Centre (NOC) and the University of Southampton in collaboration with teams in the USA and Australia.
The most important implication of this research is that it could help to inform future coastal planning and risk management strategies.
Melting Glaciers and Thermal Expansion Contribute
When it comes to the rate of sea level rise, two drivers contribute—melting ice sheets and thermal expansion.
Melting glaciers contribute about half the observed amount of sea level rise today. The other half is caused by the thermal expansion of ocean water as it warms. Melting ice flows from land into the ocean, making the water level rise.
A warmer ocean does not get bigger, but the water does expand and occupy more space because, according to the laws of physics, warmer water has a larger volume than cooler water.
This thermal expansion also contributes to sea level rise by raising the overall level of ocean waters.
Sea level rise is happening faster today than at any time during the last 2,000 years. Since 1900, global sea levels have risen by about 7ins due to melting glaciers and the thermal expansion of seawater as it warms.
Sea levels are also projected to continue to rise in the future due to climate change—at an increased rate.
These two drivers are expected to continue contributing to sea level rise in coming decades but at different rates.
Most climate models show that by 2100, melting glaciers will contribute about 70% of the total increase in global sea level, while the thermal expansion will lead to the remaining 30% of global sea level rise.
The World’s Coastal Population Is in Danger
The world is facing a massive threat, and perhaps its biggest in decades. That threat is sea level rise, and in the future, it will be a vastly different place.
Rising sea levels are making coastal areas more vulnerable to storms and floods. This is leading to significant loss of life and property damage because of the intensity of the storms and later flooding of these areas.
The first thing we need to understand is that there is no one solution to this problem. Even if we were to stop all greenhouse gas emissions at once, sea levels would continue to rise for decades.
The only way to stop the rising seas from becoming a major problem is to remove greenhouse gases from the atmosphere.
The good news is that humans are already doing this in many ways. We have developed technologies that can capture carbon dioxide from the air and store it underground or use it for other purposes such as industrial processes or fuel production.
There are also natural processes that remove carbon dioxide from the atmosphere as plants grow and convert sunlight into energy for themselves through photosynthesis.
As sea levels rise due to climate change, coastal areas are becoming increasingly vulnerable to storms and floods. Storms can cause devastating loss of life and property damage because of their intensity, as well as subsequent flooding of these areas.
It is important to understand how sea level rise will affect your area so you can take the necessary steps to protect yourself and your family.
Sea Level Rise Is a Huge Threat to Life on Earth
Why is sea level rise a big deal? Well, it’s quite simple really. Sea level rise threatens the very existence of our planet and life as we know it. This problem threatens every single person on this earth.
When you look at it this way, it certainly makes you think about your role in protecting the planet, right? It’s time to be aware of sea level rise and realise that this isn’t something that won’t affect us until the year 2100 or 2200, sea level rise is here now and threatening life as we know it!
Planet Earth goes through cycles of warming and cooling. This is normal. The ice caps will melt, and then they will form again over time.
But right now, the Arctic Ocean is warming twice as fast as the rest of the world! That’s not normal although many people are trying to make excuses that this isn’t happening or that there is nothing we can do about it.
The ice caps are melting at an alarming rate, that’s the problem. Ice melts when it’s exposed to heat, so as things like global warming become more of a threat, the ice caps in both the Arctic and Antarctic are starting to melt at a much faster pace than predicted.
If you think about this in basic terms, as more ice melts and exposes itself to heat, there is even more ice that is exposed to heat, which then melts that ice…and so on and so forth. As you can see, this is a vicious cycle that could have catastrophic results.
The issue with sea level rise is that there isn’t one specific thing we can point out and say, “stop doing that!” There are many things causing sea level rise.
Global warming has a large effect on sea levels because the melting of the icecaps is what causes sea level rise. However, other things such as pollution contribute to this as well.
Pollution adds carbon dioxide into our atmosphere which also contributes to global warming by trapping in warm air and making temperatures increase rapidly.
If you want to know why sea level rise is such a big deal, just think about what would happen if all the world’s water started rising and flooding everything!
Sea level rise is already happening, and it will continue rising. It’s not a theory, it’s real and it threatens cities and life around the world.
