The increase in alongshore winds over the northern region reduces coastal downwelling, while the increase in alongshore winds over the central region enhances coastal upwelling. Rising temperatures increase the risk of irreversible loss of marine and coastal ecosystems, including damage to coral reefs and mangroves. Coastal zones, the world’s most densely populated regions, are increasingly threatened by climate change stressors such as rising and warming seas, intensifying storms, and increasing frequency of extreme events.
Coastal wetlands, which are key defense against climate change, are also vulnerable to climate change. In theory, coastal wetlands can only survive in specific conditions. Globally, total coastal CH4 and N2O emissions decrease the coastal CO2 sink by 9-20. Southeast Asia, North America, and Africa are critical regional hotspots for climate change.
Two of the most important effects of climate change on coastal and ocean ecosystems are increasing temperatures and sea level rise. Climate and ecological emergencies play out acutely in coastal systems, with devastating impacts on biodiversity and community livelihoods. Coasts are at risk from rising sea levels and extreme weather events driven by anthropogenic climate, which threaten blue economies. Sea-level rise may cause increased coastal erosion, more extensive coastal flooding, drowning of low-lying coastal areas, and landward intrusion of seawater into estuaries.
Removing the extra ocean heat caused by short-lived gases is an extremely slow process, trapping the earth’s heat and warming the planet as a whole, including the ocean. Sea-level rise is a major effect of climate change, with unprecedented cascading effects, including ice-melting, sea-level rise, marine heatwaves, and ocean acidification.
📹 This is what sea level rise will do to coastal cities
Sea level rise is already redrawing coastlines around the world. What happens when the coast retreats through a major city?
How would an increase in greenhouse gasses affect the ocean?
Climate change is causing oceans to absorb more heat, leading to increased sea surface temperatures and rising sea levels. These changes can alter global climate patterns, such as promoting stronger storms in the tropics and causing property damage and loss of life. The impacts of sea level rise and stronger storm surges are particularly relevant to coastal communities. Oceans store large amounts of carbon dioxide, but increasing levels of dissolved carbon are changing the chemistry of seawater, making it more acidic.
This makes it difficult for organisms like corals and shellfish to build their skeletons and shells, affecting the biodiversity and productivity of ocean ecosystems. Ocean systems change over longer periods than in the atmosphere, with interactions between the oceans and atmosphere occurring slowly over months to years. Therefore, even if greenhouse gas emissions were stabilized, it would take decades to centuries for oceans to adjust to changes in the atmosphere and climate.
How do increased greenhouse gases affect the environment?
Climate change is causing warming and affecting various aspects of climate, including surface air and ocean temperatures, precipitation, and sea levels. It affects human health, agriculture, water resources, forests, wildlife, and coastal areas. Many greenhouse gases are long-lived and remain airborne for tens to hundreds of years, while others, like tropospheric ozone, have a short lifetime. Other factors, such as radiatively important substances and albedo, can also alter the Earth’s climate.
How does global warming affect the sea?
The ocean has been the primary carbon sink for human-made global warming, absorbing 90% of the heat generated by rising emissions. This leads to cascading effects such as ice-melting, sea-level rise, marine heatwaves, and ocean acidification. These changes significantly impact marine biodiversity and the livelihoods of coastal communities, including 680 million people in low-lying coastal areas, 2 billion in coastal megacities, 3.
3 billion people relying on fish for protein, and 60 million people working in fisheries and aquaculture. The impacts of climate change on the ocean have far-reaching consequences, including a loss of marine biodiversity, increased sea-level rise, and a significant impact on marine biodiversity.
What is the effect of increased carbon dioxide in the ocean?
Ocean acidification is a result of rising carbon dioxide emissions, a greenhouse gas that contributes to climate change. The ocean absorbs about one-third of all human-induced CO2, causing a change in seawater chemistry. This poses a significant threat to marine life, ecosystem health, and livelihoods reliant on the ocean. When CO2 dissolves in seawater, it forms carbonic acid, releasing hydrogen ions and increasing ocean acidity. Acidity is crucial for calcification, a process essential for organisms like plankton, oysters, crabs, sea urchins, shrimps, and lobsters.
What impact does global warming have on coastal ecosystems?
Climate change is causing species to adapt by changing their behavior, physical characteristics, or body functions, leading to expansions, reductions, or extinctions of some populations. This can affect the overall biodiversity of a region. Plants and animals may also change their geographic range in response to changing climatic conditions, such as land animals moving north by an average of 3. 8 miles per decade in the United States and some marine species shifting north by more than 17 miles per decade.
Changes in the timing of natural events and cycles can also occur, as many plants and animals rely on cues in nature, such as temperature and water conditions, to trigger certain stages of their life cycles. As a result, species that depend on each other at certain times of the year may no longer be in sync. For example, plankton, an important food source for young fish, may not be as available when growing fish need it most. Additionally, birds may find their main food source grew too early due to shifting temperatures, affecting their migration patterns.
How do greenhouse gases cause ocean acidification?
Ocean acidification in NSW is a chemical reaction where seawater absorbs excess carbon dioxide from the atmosphere, causing it to lower the pH and make the water more acidic. While marine species can cope with short-term variations in ocean pH, ongoing ocean acidification may reduce their ability to adapt. This is particularly true for marine organisms like coral, shellfish, and plankton, which use carbonate to build their shells and skeletons. Less carbonate in the water makes it harder for these organisms to form their shells and skeletons.
What does an increase in greenhouse gases cause an increase in?
The greenhouse effect represents the primary cause of climate change, as certain gases in the Earth’s atmosphere serve to trap the sun’s heat, thereby causing global warming. The concentration of these gases, including carbon dioxide, methane, nitrous oxide, and fluorinated gases, is rising as a consequence of human activities, which can be likened to the glass in a greenhouse.
How does increasing the amount of greenhouse gases affect Earth?
Human activity contributes to the accumulation of greenhouse gases in the atmosphere, causing a boost in the greenhouse effect and altering the planet’s climate. This results in shifts in snow and rainfall patterns, increased average temperatures, and extreme climate events like heatwaves and floods. Natural greenhouse gases include carbon dioxide, methane, and nitrous oxide. Their global warming potential varies.
How could the greenhouse effect lead to rising sea levels?
Global warming due to the greenhouse effect could increase sea levels by about a metre in the next century and several meters in the next few hundred years by expanding ocean water, melting mountain glaciers, and causing ice sheets to melt or slide into the oceans. This could lead to melting or sliding ice sheets into the oceans. Copyright © 2024 Elsevier B. V., its licensors, and contributors.
What are the threats to the coastal ecosystem?
The effects of climate change, including increased precipitation, an elevated frequency of storms, and ocean acidification, are exerting considerable pressure on coastal ecosystems. The Authority is advocating for an integrated, comprehensive approach to the protection and restoration of these ecosystems, which are of paramount importance for the continued health of the Reef. The strategies in question can be found in the aforementioned position statement on coastal ecosystems.
How does global warming affect the coastal areas?
The phenomenon of global warming is causing an increase in the temperature of the Earth’s atmosphere, which is leading to the melting of ice at the poles and in glaciers. This phenomenon results in increased ocean water levels, which may potentially lead to the sinking of coastal regions and the melting of glaciers, as well as the sinking of oceans.

12800-+ years ago the oceans rose 400 feet practically over night swallowing up coastal lands around the world. Maybe we all should have been taught this while in school. Now you know . If you live next to any body of water, river,stream,lake,sea or ocean don’t complain . Just move. That’s all it is.
Looking at some world maps, there is often a pale blue outline around areas of land. Some seemingly actually joining land masses together. This is shelves or offshore shallows, where once there was land. The process continues, if now at an accelerating rate. I live in Key West Fl, US. 4.3m above sea level. Property values are extremely high here. One day it will just disappear into the rest of the pale blue patch surrounding it.
It’s not technically the water from melting glaciers that’s causing the sea levels to rise (it contributes, but not much). It’s the fact that as water molecules get warmer, they expand. Joe Scott did a article on that you can look up. The main way that melting glaciers actually affect the sea level is the fact they reflect sunlight away from the Earth’s surface because they’re white, hence keeping the Earth cooler. As the surface area of glaciers decreases, the less light is reflected, making the climate warmer, and in turn, the water molecules of the ocean expand and push back the shorelines. You can see this in action when you take a chilled unopened water bottle from the fridge and let it sit out for a while to warm up. You’ll notice that the bottle starts out crinkly and malleable when it’s cold, then when it warms up to room temperature or hotter, it becomes hard to squeeze.
We have been told for at least 30 years that sea level rise will inundate coasts in the near future. NYC was supposed to be under 10 feet of water by 2014 even if the estimated are off by several years shouldn’t NYC be under at least 4 or 5 feet of water by now? Why are Venice, Italy, Belgium and the Netherlands not under water today? You do know that places like Miami are actually SINKING not being covered by sea rise?
A very simple solution is, MOVE AWAY FROM THE COAST!!! Cities have relocated many times in the past. Does anyone ever think about flood zones?? No matter what is done to control rising sea levels, there are STILL tidal waves / tsunamis, and larger than normal hurricanes. Look at the aftermath of the recent hurricane flooding of Florida, New Jersey, South Carolina, Texas, Louisiana, …..
My city has had flooding on the regular, and in the last 3yrs we’ve had two sinkholes and a tornado. Things our area had never had before. (One of the sinkholes was HUGE, the size of an Olympic swimming pool, the other was admittedly minor.) Thing is? I live in the capital of Canada. That massive sinkhole I mentioned? Yea it happened a block away from Parliament. Ottawa’s built on the Ottawa River, which gets fresh water from melting ice and feeds into the ocean, so it’s directly impacted by this shit.
This is happening around the world, because people loved to have a short way to the ocean, thats why they built their houses along the sea, but now those who want to keep their feet dry have to move up high above the sea, I remember that when I lived up in north of Norway and I read a lot of local papers, and there I found an ad about the rising of sea levels and that Norwegian companies were looking at this seriously and I hope we hear from them soon!!!
Yes, the sea levels are rising but the land is also subsiding to accommodate it. Those who are prepared are not scared of these natural changes, although human activities may have accelerated the process somewhat. We cannot stop what has always been. Earth is a living, moving system. As part of these processes, land fissures will continue to occur, mountains will fracture, slide and begin to fill in valleys and through rain and wind, be spread out and/or redistributed. This will change the topography of everything we currently see.
Scaremongering …in 1983 we were told the ice caps would be gone and sea levels would rise by 70 metres or 200 feet. It didn’t happen. No mention has been made of land upheaval caused since the end of the ice age Most of the issues we have are man made . The expert may work for a non profit think tank but what is their agenda ?who funds them ? How much is he being paid and most notably look at their answers to these problems. Massive expenditure. Someone is making some serious money.
Well strengthening the coastal areas is a good idea anyways. Even if sea levels drop, erosion will still occur. That community in Louisiana that is moving isnt because of rising sea, its because it is built on a lowland silt in the Mississippi River delta. New land forms there and then erodes away. Its been going on forever. Since we put levys and Dams all over the place, the silt that naturally flows downstream isnt forming new land in the delta, the ocean is still eroding so the land is just disappearing and not naturally being replaced. That is the situation with many coastal wetlands. I lean toward climate change. I also think we cant stop it. I think we should focus on minimizing it as much as we can. If it turns out we were overreacting, fine we now have better protection from the occasional floods and natural erosion.
I was thinking maybe as a stop-gap savior to impending sea level rise, it may be worth a feasible study of creating a vast inland ocean in a large arid area: how to make it a viable habitat, implications of it’s effect on weather: If it could be designed to siphon the top warmer ocean layer. Just a thought
I’m sure you’ve heard of the concept of a Sahara Sea, wouldn’t going through with that endeavor lower sea levels by at least a few inches due to so much water being diverted into the new sea? I’m not saying that’ll solve the problem, just thinking that would slow down the rate of rising tides a bit while also tackling another ecological issue.
As a Government worker I went to one of these in 2003….various maps showing shaded areas of a 100kilometre stretch of coast where I live. Diagrams showed regular inundation zones expected by 2025-2030. Then those zones permanently inundated by 2050-2060. It was all very well done and quite convincing back in 2003. So what’s changed here? Nothing much at all. Yes some coastal erosion in places but no sea level rises into regular inundation zones. No sea water encroachment at all. All the houses that were predicted to be flooded in the low lying zones are still habitable in 2024 just 1-5 years short of the catastrophic inundation predictions. Those properties still being bought and sold. Real estate prices are premium for these coastal homes. Go figure.
I live 4 miles from the beaches of the Gulf of Mexico. Instead of ruining the global economy trying to change the climate, it seems to me it would be cheaper to adapt to the climate change. By the way, I have lived here since 1980 and fish the waters here around Pensacola and I have never seen 1 millimeter of sea level rise in 42 years. When do you all think it is going to start? Lol….
Mankind has the hubris that climate change can be controlled or dealt with. What everyone seems to miss is that it is an accelerating process, and the rate of acceleration is accelerating. Greenland is melting 6 times faster than in the 1980’s. OK, but in another 20 years it will likely go another 6 times faster, or 36 x faster than the 80’s. And then, faster yet in 20 more years, and then faster yet in more time, etc etc. These multipliers will begin to have real effect in 50 or more years. The rate of sea level rise will be so fast by 2100, that it will become obvious to everyone that investing more in sea walls and other devices is just a waste of money. Eventually, there will be no other option, but to abandon the coastal cities.
In my opinion: -At this moment the two species in danger of extinction should be observed with more interest due to their resilience and vigorosity as a nich. Taking the argument of the new species as invasive, I believe it should not be treated as such merely because of its well adaptations to its immediate environment. In any case it should be native because it’s Center of Origin is the only region it inhabitants, it was not introduced. One of its parentals was introduced. The value of these two species can be reflected later on by organisms in the ecosystem further adapting to this new uncolonized space. This new ecosystem might even harbor more than the already 100 species. As regards to these, they might move on to new regions do environmental pressures. As cons of this it might take years to occur, also their might be lack of interest. The questioning of what is nature comes from its misunderstanding.
This illustrates a gradual rise in sea levels. What is not being taken into account is the fact that the warmer our planet gets, the faster the planet gets warmer: the rate of change is ever-increasing. By the middle of the 21st century, every coastal city in the world will be at least partly in the ocean. And then there is the fact that most of the people in the world live on the coasts, so we will have billions looking for new homes, with all the associated problems from that migration. And that’s not even considering all the other effects of climate change, such as stronger, wetter storms and longer, hotter droughts, fires, etc. We’ve already seen some of it.
Coastal towns and cities have been dealing with this since the beginning. When the Ice Age ended, things began to warm and oceans began rising. The cycle naturally moves faster toward the end-temps and ocean levels rise more quickly. It’s just science/physics. Who is Verge Science? Best to read stuff from leading universities.
I can imagine Manhattan being protected by a system of barricades and dikes; there are relatively narrow openings between the city and the Atlantic, which would be more easily fortified than cities that sit directly on the ocean. Miami, on the other hand, would be a lot more difficult to protect. Not only do you have to worry about flooding, but rising groundwater tables will affect the land as well. Back after the 1900 storm, Galveston, TX, raised the entire city by 15 feet. This was relatively easy given that very few structures survived and those that did were generally small. They just jacked everything up 15 feet and filled in underneath with dirt. They built the 17-foot-tall seawall along the ocean to help protect from future storm surge. This would obviously be insanely expensive — unrealistically expensive, honestly — for most coastal communities, but it might be the only solution for some areas, aside from totally abandoning those communities.
Fort Denison sits within the city of Australia’s harbor, Sydney. It is arguably one of the most reliable places to measure sea levels due to its position within the largest body of water in the world, with America and South America at its far east boundary. Fort Denison has been used to measure sea levels since 1914. Sea level measurements have raised and lowered since then, mainly due to the influence of the moon and other planets, but in 1914, the mean sea level was 1.11 metres. In 2019, the same mean sea level was just 1.05 metres, a DROP of 60mm. This is an indisputable fact. For most, we are seeing erosion and NOT sea level rises. Erosion has happened since water lapped land and is perfectly normal. The scare tactics of those who say the sea will rise substantially never ceases to amaze me and the reality proves differently.
Hi, all the extra background noise and music is really distracting. I hope you will eliminate it when people are talking. It’s okay to have sound effects when people aren’t talking but when people are talking it’s very distracting and unnecessary and unpleasant even. Please consider reducing the background music.
Dear Verge Science Team, Isn’t one way to deal with rising ocean levels by starting with putting in rust-proof, steel pilings driven into the bedrock of New York City.For example, they could start block by block. First put in pilings that will rise to a platform of, say, 3 meters. On the platform, once it is secure, 12 feet above street level, they could begin to reconstruct the new entrances to be used from the new level. The lower part of the building could remain and the ‘new’ foundation’ fortified. I am an inventor, and I know one thing: There are ways to do things with existing structures that can be renewed and repurposed using things already in place. The idea is this: Little by little, Manhattan could remain the same, but a new street level would gradually be put in. By 2100, say, the low-lying areas would be ready for the 12 foot rise in foundation level to be put into everyday action. The architects would see the holes in this plan. It’s off the top of my mind. We must incorporate the sea level rise in our thinking and realize that from now on, the earth is going to re-adjust to a massive influx of fresh water pouring into the océans and changing coastlines around the world. If our new structures can simply be elevated to meet each new rise in ocean levels, it can be a win/win situation. The challenge is to keep the coastlines as they are but adapt & build a new city-sea-scape.
People are ignoring one fact. The coastal areas of such cities as Manhattan are built on man-made land. The original coastal line of New York City was much different before people began changing it. We extended the land and built one of the largest metropolis’s on the planet there. This was a bad mistake. Climate change or no climate change, eventually mother nature is going to win, is going to take back what is hers. Just look up a map of New York City from the 1700s and compare it to today. The shape and coast-line is much different, it was much smaller back then.
I have a idea too combat rising sea levels,when you get in a bath the water rises,when you get out it goes lower again,so you take every mortal thing out the sea,fish the waters more than ever,bring up shiipwrecks,airplains,rocks sand,rubbish and anything possible,and then start making huge lakes,,ponds pools all over the place even in deserts,you could even drain the water to the coldest places on earth for it to freeze
Construction of the infrastructure to protect communities from sea level rise and the accompanying severe storms and hurricanes is going to require not only huge amounts resources and funding but years to complete. There is only one strategy that can push back the date of reckoning while other measures are undertaken. This is to website as much water as possible to regions of the planet that are essentially barren and uninhabited. There was a time in the planet’s history when water covered many of the low lying regions that are today desert or near-desert. A globally-funded series of projects to dig canals from the coasts and into the interiors of each continent might just be enough to hold back the seas until other measures (including reduction in CO2 emissions) can be broadly implemented.
I disagree with what she says about our coastal cities are first in line to feel the effects of climate change. Everyone is already feeling the extreme temperatures, and unprecedented fast moving fires are threatening our interiors. It has always bothered me that sea-rise and loss of coastal land is prefaced as the chief concern. By the time we see a big rise in sea levels the bulk of humanity will have died off due to starvation, heat, and unimaginable weather events.
The Prodigy has a solution that will prevent sea level rise……. I may be using the terms wrong but imagine moving dirt on top dirt to make the ground higher such as Puerto Rico for example…..when you layer rocks on the of the dirt and dirt on top of rocks it’s providing a higher level of the ground then layer it with concrete if necessary which will 100% work in my theory that will increase the ground levels. I’m 100% sure this will work.
Over 400 years ago, several castles were built on the cliffs of the oceans near them. The ocean was literally at the cliffs directly below them. Today, the castles are a mile or more from the oceans. Nobody has been freaking out over the centuries that the oceans have been receding, Instead they have built up this new land, so my thought is who are we to say that these waters will not return back to the cliffs of the castles that they once crashed against. 🤔
The saddest thing is the ones who’ve done the most damage to our environment are the ones who will see the fewest amount of consequences from climate change while the less fortunate who have done very little to accelerate the climate are the ones who will pay for it the most. We are in desperate need for politicians who will recognize these problems and actually do something about them.
The sea is enormous and you must put a lot of water in it to raise the level by one millimeter. Try it yourself. Fill your bath tub with water and put one drop of water in it and there is no raise in the level. Put a cup of water in and you have about the same result. Put a bucket of water in and you will see the the difference in the water level. Again you need billions of liters of water to raise the sea level by 8 meters.
Do what Dubai did with the Palm Island and the many other man made land masses they’ve created since by dredging rock and sand from the ocean floor and meticulously dispersing enough of it to create vast coastline extension as well as incredibly secure foundation for the expansion of infrastructure. Will it be costly? Hell yeah! It will most definitely incur a a large amount of New York’s annual GDP but imagine the financial toll it would take on Manhattan as well as the 4 other bureaus if preventive measures aren’t taken to protect a major market like NYC? It would pay for itself within 5-10 years. I can’t think of a better investment than to expand the coastline along the eastern seaboard because now we have the technology!
They’re not thinking or talking about how heat causes water to rise and couple this with storm surges that can lift water incredibly high also you’ve got water as high as four or five stories. I don’t think people are quantifying this. One hundred years is seriously optimistic. The water is rising now so now is the time for families to consider moving to higher ground. There are no second chances when it comes to escaping storm surges.
From another article elsewhere: “It’s a little puzzling that scientists should be surprised that the Earth’s coasts aren’t shrinking. After all, relative sea level changes are not the predominant determinative factor affecting the growth or recession of land area. Coastal erosion and accretion, tectonic uplift and subsidence…are far more influential.” This means the coastal land is getting LARGER, not SMALLER. Yes, Florida may be losing coastal area, but over the entire Earth, it is not true. That doesn’t mean we shouldn’t work at figuring out how to help Florida and other coastal cities fix their problem, but it does mean that the data for this article was “cherry picked” to create fear.
Faster sea level rise from one place to another is literally impossible with all other factors being egual. Unless the properties of water have changed! Some land masses,however, like Manhattan are known to be slowly sinking while others in the world are rising. Google new islands created since the beginning of the 20th century. It’s quite a list.
Given that sea levels have been higher in the past it is no surprise that coastal cities will be affected. Those cities didn’t exist in the past when there was no ice at the poles or Greenland. Sea levels are gonna change in the future just as they did in the past. We have no choice but to make the adjustment.
Interesting. But, I fear, only scratching the surface of the problem – which is worldwide and not just American (I’m speaking as a Brit – don’t hold it against me). Speaking as a pragmatist I’m not saying climate change is happening or not – but let’s at least consider the implications of, say a 2 meter (7ft) rise in sea level over the next 100 years. That’s within the lifetime of most people’s grandchildren. Beyond our lifetime but within that of people we care about. What they will have to live through. If these predictions are correct – andeven if not – can we ignore the possibility? How much land will become flooded? How many cities and towns? How many people displaced? Where will they go? How much agricultural land lost? How much more needed to make-up the loss? What social impacts will be involved? “Locals”, wherever they are, already resent “incomers” – how are they going to feel when pressed to accept double or more foreigners? With associated inter-racial and other social tensions? How much is this likely to cost? Answer: A LOT. And then some! Who will pay? Answer: Everyone – by the dispossessed in losing their livelihoods and homelands; everyone else by safeguarding their own homes and in absorbing those dispossessed into their communities. We have choices. We can ignore the warnings altogether. And it will be up to our grandkids to pay the price. We can go all out to prevent these things happening – which may be excessive and unnecessary. And there are many who will argue against this.
Most of our land mass was once sea bed. Those are the plains we now grow our crops on and where our cities are. If you look at satellite images, this becomes obvious, specially if you look at desert regions. When the ice on the poles melts, the sea will rise much higher around the equator than you think since the land masses at the poles will rise. There is ancient shoreline at 250 meters in Africa. Those coastal settlements had to move eventually because the climate changed. I still don’t believe we are the cause of climate change or that we can do anything about it but adapt, like we have for millions of years.
It would be better to stop building on the low lying land and plan for where the new coastline will be. Any building over a certain age in lower Manhattan should be demolished and made into a parking lot. There is a huge cost to maintain a sea wall. Huge cost pumping water out . Same thing with New Orleans, start getting rid of the low lying buildings and move to higher ground. This should have been done a long time ago. Canadian north is huge and so is Russia. India will be under water. Where will the people go. They will go to Siberia.
Along with the possibility that we may have flooding as we prefent it.i suggest assessable evacuation stations at commonly known flooding zones.most people would have to be rescued by boat. Down town will get hit harder real soon from something. Be prepared for extremely huge snow storm. Dropping 7 to 10 ft with in a couple days time. That’s coming soon also.
Stop dumping stuff in the water. Stop building more floating items. Stop building more land closer to water. All of that lead to water raising. It like you having a water bath. And u decided to throw yourself in and add lots of heavy toys that sink and float. And plant more plants that Absorb water. Like a mangrove. That might help in a million years.
Where is the measurements? Where have you measured the sea level rising? Also the rising of an ever raising and lowering body of water. Aka tides. I’ve been scouring YouTube and google for actual science showing that sea levels have ALREADY been rising. Also what do you mean you can plug the freezer back in? What do you think the ice age was?…
Instead of quoting anonymous non climate scientists try quoting the US Navy and it’s demand for a new shipyard due to the Norfolk shipyard having serious issues with sea level rise. The increasing average rise of sea level has little to do with reality. The rate of sea level rise at the area around the Norfolk Shipyard is many times the average rate. Thermal expansion is the primary cause of sea level rise which is why islands in or near the equator are more vulnerable than at higher latitudes. Obviously having water expanding do to warming is going to play a role in melting ice as well another positive feedback loop. It’s worth looking into the navy, army, CIA and other institutions writings and findings when it comes to their understanding of the implications sea level rise and freshwater scarcity is starting to have on areas at the front line of climate change. Get ready for million man caravans coming from central america. Also for those that like to argue with anecdotes and non official predictions from dubious sources who claimed Mt. Everest would be ice free by 1950, instead read about the history of the Northwest Passage. You’ll find that it crossing that passage linking the Atlantic and Pacific has from the first crossing in the 1890’s all the way till 2007 or so, was the realm of high latitude sailing vessels small enough to get through the narrow openings in the sea ice. Since 2013 the Chinese were saving big bucks by passing the Panama Canal and traversing the NWP with some help from Russian Ice breakers.
Its all too late just recently on the 30th of Sep 2019 a huge piece if antartic ice size of Malta has boken away from the Antarctic so its happening, 7 times faster than they thought, they where for years studing the top of the ice, with sea temperatures rising it was melting at an alarming rate below there are lakes in the Antartic the size of Europe.
checks west coast cities of the US Oh yeah, we mostly built on hills and high ground, our only serious change will be what we grow in the Sacramento valley. Even then a flood barrier similar to that on the Thames would be no problem on the Carquinez Strait. I’d honestly be more worried about flooding from heavy rains here.
You can’t stop mother nature from flushing the toilet. Continents have moved and sea levels have risen and Fallen over the millions of years. You can’t stop that kind of change. You just putting a Band-Aid on it climate change is really the best defense but it seems impossible! At my age I probably have another 25 to 30 years left on this Earth I can’t imagine what it’s going to be like in 30 years. I truly feel sorry for the children being born today. We have left them the mess to clean up!
