Antarctic Peninsula Climate – A Change in Krill Ecosystem
Antarctic Peninsula Climate – A Change in Krill Ecosystem
Antarctic Peninsula has been experiencing warming trends for over 40 years with an increase of 2-3 C, thus correlating with lower sea ice conditions in the Amundsen Sea and Bellinghausen Sea. Warming temperatures around the Antarctic Peninsula is changing the dynamics of the ecosystem. The rise in atmospheric temperature is causing increasing in melting of freshwater glaciers and ice shelves. Fresh water emerging into the sea counteracts the salinity within a regional area. Changes identified are;
• Decrease in sea water salinity up to 60 miles offshore
• Lower sea ice
• Decreased krill population
• Increased salp (open ocean tunicate that is reminiscent of a jelly-fish) population
• Increase in cryptophytes (single cell phytoplankton algae)
• Decrease in diatom phytoplankton
• Increase in carbon sequestering in deep ocean sinks
• Decrease in carbon availability in the food chain
The Antarctic Krill (Euphausia superba), a small shrimp like crustacean is the most important zooplankton species associated with the sea ice and plays a crucial role in the Antarctic food web. On a regional basis the amount of krill appear to be declining in the southern ocean. There are definitely lower trends in krill population during lower sea ice years around Antarctica. Part of the rational for the population decline is that ice algae rely on the sea ice for protection and growth. The krill need the sea ice in order to feed on the algae and phytoplankton.
Krill occur in groups or large swarms. They are less than 3 inches in size and feed primarily on phytoplankton and sea ice algae. Krill filter diatom phytoplankton out of the water column and scrape algae from the sea ice. Apart from frequenting the sea ice to feed, krill in particular juveniles, seek protection from predators in the many nooks and crannies formed by the deformed sea ice floes. Krill is the staple food of many fish, birds and mammals in the Southern Ocean. The biomass of Antarctic krill is considered to be larger than that of the earth’s human population.
Sea- ice algae utilizes atmospheric carbon dioxide for its energy source, the same as plants do on land. Krill diet of the sea-ice algae and phytoplankton is essential for converting the carbon for use in higher animals such as fish, birds, and whales. This carbon conversion is a very critical role in predatory nutrition. Additionally krill do eliminate some of the silica from the diatom shells and carbon in sticky balls that sinks nearly two miles into the deep ocean. These cold, deep waters are able to contain carbon dioxide and prevent the gas from rising to the surface, thus immobilizing carbon that is not passed into the food chain.
In recent years there have been increases in algae phytoplankton called cryptophytes. Mark Moline, California Polytechnic State University, states that the cryptophyte population correlates with warmer temperatures and lower salinity waters that are produced by the melting of the freshwater glacier. Cryptophytes measure around 2 mm, while other plankton in the Antarctic waters are much larger and measure 15 to 270 mm. Along with the increase in cryptophyte population an increase in salp, a pelagic tunicate, population has also occurred. There are differences between salps and krill. Salps feeding efficiency is capable of grazing on smaller food sources less than 4mm, whereas, the Antarctic Krill efficiency declines on any food less than 20 mm. The salps compete with krill for the phytoplankton and thus decrease the krill population. Additionally the salps feed on krill larvae, which also cause a decline in krill numbers.
The warming trend in the Antarctic Peninsula is showing a pattern of increasing cryptophytes over other phytoplankton and the increase in the salp. This influence is due to the low sea ice and the lowering of the salinity in the seawater. Salps and cryptophytes do better in the lower salinity, while the krill and other plankton are unable to tolerate the increased freshwater regime from the glacier ice melts. This selectivity gives preference to the salps as the dominant species while decreasing krill abundance. During lower sea ice seasons the density of krill declines while the salp population increases.
Carbon sequestering into the deep ocean from the algae and phytoplankton occur by both the salp and krill. Both species eliminate the atmospheric carbon received from the primary producing algae by producing fecal pellets by the salps and sticky balls by the krill, thereby, reducing the amount of carbon dioxide in the atmosphere. The salps though sequester more carbon into the cold deep ocean than the krill. However, the krill provides the most efficient pathway for carbon transfer up into the food chain. The cryptophyte dominated waters are less efficient in the food chain due to increased feeding by salps and the difficulty of the krill to utilize the cryptophytes as a food source. Migration patterns by penguins are changing, in part due to the changing krill population. Krill is a mainstay diet for penguins, and if the krill population changes, many other ecological changes occur with it.

Mobile Car Wash Rules Slated City of Oxnard CA
The City of Oxnard, California is concerned with the quality of its storm water and rightfully so, as it has made great strides over the years. Oxnard CA is also home to the gateway to the channel islands with some incredible beaches and nice resort style living, and all that storm water leads to the ocean and those beautiful beaches. Thus, the city has chosen to start cracking down on mobile car washes.
This should not come as any surprise to anyone, as the city had previously implemented many programs to help clean the storm water runoff. They had developed a nearly bullet proof NPDES plan to insure clean water. The beaches never looked so good and this recent ruling to finish that job nearly a decade and a half later has come all the way down to washing of cars.
Our company had dealt with this issue in the late 80s and early 90s and helped write all the NPDES BMPs for several counties near there. The devices used are fairly easy to buy, and it really doesn’t take much, further it is my contention that all mobile car washes ought to follow the rules to protect the environment and there ought to be no excuses on that.
Indeed, over the years, we’ve worked with many cities on this, in fact, one thing we did was join the committees to help write the original BMPs for surface cleaners in Ventura County, CA where the City of Oxnard is located. A mobile car wash operator should not only follow the rules but be part of the solution. Think on that.

Save the Planet by Becoming Energy Efficient
Save the Planet by Becoming Energy Efficient
Save the planet! As Earth Day approaches April 22, what are you doing to get ready? Earth day is an event that started to bring attention to our environment. How we handle our garbage reflects our environment. Here are three tips to help save our environment.
- First, recycle. Recycling is taking some of our garbage and reusing it, directly or indirectly. To recycle a water bottle, you may reuse it again and again. But for gallon milk jugs or 2 liter soft drink bottles, you may opt to collect them and bring them to a recycling center. The recycling center will forward them on to a company that will melt them down and reprocess them.
- Second, shop efficiently. Try using what your Grandma used when she cleaned her house. Try using vinegar and baking soda. There are lots of sites that recommend natural cleaning products instead of chemicals. Also, buy those products in bulk. It reduces packaging which ends up in our garbage dumps and it may be cheaper, the more you buy, the cheaper it is.
- Third, conservation. Since I already have compact fluorescent light(CFL) bulbs installed, turning off the lights when I leave is the next best thing. My Mom always told me to turn off lights when I leave a room. She was right. Using more electricity only raises your electric bill. It will also increase your carbon footprint.
Education is a goal of Earth Day. Educating everyone from adults to children can get involved. Challenge your kids to come up with projects to bring attention to our environment. When we teach our next generation, we are saving our planet. But first, we must start ourselves. Be a steward of what God gave you. Become energy efficient by recycling and conservation. Our planet is worth it.
And now I would like to invite you to join me in learning energy saving tips you can do yourself to decrease your electric bill at http://energyconsciousconsultant.com Energy conservation should be out goal.
Go Green With Natural Finishes
Go Green With Natural Finishes
Finishes are coatings that are applied to the external and inside surfaces of walls to protect them from the elements and from wear and tear. They also improve the appearance of the structure and are used to enhance the design of rooms.
Petroleum, our main source of oil-based wood finishes and paint, is a non-renewable resource. There are now paints and finishes on the market that are derived from a renewable resource, which in a small way, helps to reduce dependence on oil, and contributes to a more sustainable world.
The basis for these products is whey, which is a product of cheese making, and which has a high biochemical oxygen demand (BOD). This increases the burden on waste treatment facilities, and can also pollute our natural water sources. In the last ten years, this by-product has been used for many new purposes, one of which is natural wood finishes.
When choosing paints for your decorating, use the low or no VOC (volatile organic compound) paints. For hundreds, no, thousands of years, earth, clay and lime have been used, both in hot and cold areas of the world. And now this knowledge is being readapted for contemporary use. If you do any redecorating or new building, it makes sense to contribute to having green, healthy surroundings.
Low and no VOC paints have less smell and less impact on air quality. EPA studies have shown that indoor air quality is up to five times more toxic than outdoors, mainly because of toxic emissions from paint and finishes. This particularly affects anyone with allergies, asthma, or chemical sensitivities. With the new “green” paints, there will be lower contamination of landfills, groundwater, and the ozone.
Switching will not cost you more. Cleanup is easily done with soap and water, instead of toxic chemicals, and brushes can easily be cleaned and reused. The paint is still washable, and is far less harmful to you, your pets, and the environment.

How to NOT Be One of Them – Farmers Are Being Pushed to Increase in Size Or Get Out!
It doesn’t matter what size it is, your farm is an ever increasing asset, even more so if you can provide chemical free, clean food.
Australian conventional food prices are forecast to quadruple in price over the next five years. The reason is Asia. We are in the middle of a global revolution in the way we think, eat and live.
This week I received this news from Craig Sobey who has recently toured China with representatives from five city councils, Austrade and Regional Development Victoria and reports that there is a real opportunity for all to take a significant market share in this period.
Basically, if it is Australian and premium quality there is a ready market. Australia is seen as a source of safe food regardless of whether it is organic or conventional. At this stage price does not appear in the conversation, just consistent supply and traceability. The interest in all products represented included convenience food packages (pre-cooked), meats, dairy, wines etc.
Did you know:
- This co-op now owns China’s fifth biggest supermarket chain with over 500,000 stores.
- There is a farmer’s co-op representative with over five million members?
- 6,000 of them over 30,000 sq metres. The supermarket turned over 18 billion dollars in 2007 with revenues growing by 150 % per annum on average.
- They have offered an entire Australian Pavilion for Aussie produce including organics in their premiere stores in Beijing and Shanghai. Organic Wines were the big attraction.,
- China creates 80,000 millionaires each year.
- There are over 350 million middle class and a niche market of super wealthy Chinese? (Craig told me that French wine is selling as much as $600 a bottle and even one watermelon cost $40!).
However there is real interest in China for organics (which they refer to as Green Food) and particularly food safety/ traceability which is the paramount concern for all serious buyers they met. A new Australian wide network (not for profit) company is being formed for all sections of the organic market. This is so that a pool of members can tackle the export markets together. Its goal is to give you an export premium to help make membership very appealing.
The time is ripe for all growers to stop and think about the future of their farming. What choice will you make? Your future will depend on it. Even if all of Australia’s certified organic farmers, processors etc. were to unite they could not supply the market in China alone and therefore there is untapped potential over the next ten to twenty years to be further developed.
Farming Secrets is a club for farmers who want to farm healthier and more profitably. Farming Secrets reconnects them with the experts through supporting them with one to one help and constant support from experts in order to fast track their farming goals that much quicker.

THE 3 Rs – Reuse and Recycle, Lazy Ways to Reduce
THE 3 Rs – Reuse and Recycle, Lazy Ways to Reduce
The 3 Rs (Reduce, Reuse, and Recycle) is no longer simply a mantra for environmental activists, it’s a ticket to saving you money while you consider the planet. The 3Rs ask you to buy less, reuse more, and recycle products at the end of their useful life-wonderful guiding principles for reducing our environmental footprint and bringing our lifestyles into balance with nature. But in practice, how many of us are really willing to cut back on the stuff we want to own, to reuse what we’d like to throw out, and to recycle when doing so is often incredibly inconvenient? Fortunately for budget-conscious Lazy Environmentalists, the 3Rs are receiving a twenty-first-century facelift, making them easy to implement and even easier on the wallet.
Reduce, the first of the 3Rs, releases you from the hassle, expense, and waste of unwanted stuff while helping you use less energy and create less trash. And while most of us can’t imagine life without our most prized four-wheeled possession, the first place to embrace Reduce is with our cars. That’s because our automobiles generate about half of our personal greenhouse gas emissions-the other half comes from our homes.
Today, you can enjoy the freedom of being in the driver’s seat while eliminating all of the expense of owning-or leasing-and maintaining a car by joining a car-share service. Zipcar is leading the way. Available in more than 40 U.S. cities, Zipcar lets members locate cars conveniently parked at designated spots around the city and reserve them for an hourly fee (typically between $10.50 and $16.50). Members arrive at the parking spot, swipe their membership card over the windshield sensor to unlock the door, hop in, and go. There’s no need to pay for gasoline or insurance; Zipcar has got you covered. You won’t sacrifice your ride either; Zipcar lets you choose from models like the BMW 325, Mini Cooper, Honda Fit, Volkswagen Jetta, Toyota Prius, Honda Civic Hybrid, Volvo S40, Mazda 3, and Subaru Outback. According to the company’s surveys, over time Zipcar members reduce their car usage by as much as 50 percent. Zipcar estimates that each of its cars removes the equivalent of about 15 privately owned vehicles from the road. Other car-sharing services are popping up across the country and around the world. Visit Carsharing.net for a comprehensive list.
Reuse-the middle child of the 3Rs-has been a part of our lives before we were “eco” anything (eco-conscious, eco-savvy, even a tentative eco-curious). Think about it: Every day, we reuse items like T-shirts, cereal bowls, and underwear without a second thought. We don’t toss them after one use. We reuse. The secret to twenty-first century Reusing is to discover how to reuse other people’s really cool stuff as well as our own.
Reuse logic is in effect at Goozex.com, where gamers gather to swap their video game. Visit the website, create an account and list the games you own that you’d like to trade. Then Goozex quickly locates other gamers who want them and makes instantaneous matches for you. With each game you mail, you earn Goozex points, which you can then use to acquire the games you want from other members. Instead of spending lots of money on new games (and paying for all that packaging waste), you’ll pay Goozex $1 each time you receive a game. Whether you’re partial to Xbox, Wii, Nintendo, or many other gaming platforms, the Goozex trading community has got you covered. Get your reused copy of Call of Duty 2 or NCAA Football 09 today.
Swapping websites are emerging in all kinds of categories. Bookworms can browse more than two million titles available for trade at Paperbackswap.com. Movie collectors can visit Swapadvd.com to trade both new and classic DVD titles. CD fans (you know you’ve still got ‘em) can tap into more than 130,000 titles available at Swapacd.com. And new and expecting parents can trade for baby strollers, bibs, bedding, bumpers, and more at Zwaggle.com.
Recycle, the last of the 3R trio, is the most transformative of the Rs. When we recycle, we’re giving used products the chance to be reborn as something new. That’s especially the case thanks to companies like Preserve that has partnered with Stonyfield Farm to recycle its yogurt cups-from organic yogurt, of course-into ergonomic plastic toothbrushes, razors, and an assortment of colorful kitchenware (and now also does the same with Brita pitcher filters).
TerraCycle, another green innovator, is on pace to redefine much of America’s relationship with trash. The company that began with its signature Plant Food-made from worm poop, packaged in empty Pepsi bottles and sold at the likes of Home Depot and Wal-Mart-has evolved into an innovation powerhouse that continually introduces new products made entirely from waste. Take the E-Water Trash Cans and Recycling Bins available at OfficeMax for $10.99 each and made from crushed computers and fax machines (that would otherwise end up in a landfill). Or the rain barrels and composters made from Kendall-Jackson oak wine barrels that sell for $99 each at Sam’s Club. They’re both prime examples of a company that sees opportunity where others see garbage. In so doing, TerraCycle helps us make attractive choices that are mindful of the planet and our wallets.

Start Recycling Today
Recycling is like exercising – everyone knows we should do it, but not all of us do it as frequently as we should and many of us don’t do it at all. However, there are tons of reasons why you must make an effort to recycle as much as feasible. If you have not been diligent about recycling, this article provides some great reasons why you should start.
1. Recycling cuts back on global warming.
2. Production of certain materials from the start can release serious amounts of CO2 into the atmosphere.
3. Recycling paper saves trees – for each ton of paper recycled, 17 trees are saved. Each of these trees can extract around 250 pounds of carbon-dioxide from the air in a year.
4. Recycling makes us more energy-efficient. It frequently takes a great amount more energy to form something from nothing than to reuse it.
5. It keeps our landfills from overflowing. We are fast running out of space for landfills especially near towns.
Beach towns have been dumping trash into their seas for years to by-pass the difficulty, but with widespread sea ecological collapse, this isn’t longer a practicable option. Worse yet, it’s hard to find land in suburban and agricultural areas whose residents will permit landfills to come into their areas without a fight. The squeeze for rubbish heap land is only going to become worse in the future.
Recycling gives us some hope. Studies show that 60% to 75% of rubbish in landfills can be recycled. That suggests that if everyone recycled, we would have 60% to 75% less rubbish in our landfills, and we’d need at least that far less land for rubbish disposal. The rubbish in landfills is mostly not treated in any way it’s simply thrown in a huge hole and buried over. A lot of this rubbish isn’t environmentally friendly or readily biodegradable and it is unsurprising that contaminants can get into our water. It is also a major reason why it isn’t safe to drink from streams and brooks when you are hiking and camping even when it’s like you are in a spotless environment. It reduces air pollution. A lot of factories that produce plastics, metals, and paper products release poisons into the air.
For instance, plastics are usually burned in incinerators. Plastics are made with oil, and that oil is released into the atmosphere when the plastic burns, creating significant greenhouse-gas emissions. From manufacturing to processing, from collection to invention it’s common knowledge that recycling is an expansion industry, earning billions of bucks yearly. Our desire to recycle is only going to grow more insistent as populations grow and as technology changes. It adds to property worth. It is obvious a rubbish heap near your house can decrease your property values significantly. Recycling decreases the quantity of land required for landfills. This decreases the quantity of homes near landfills, keeping property values up and house owners cheerful. The more folks recycle, the less landfills we need and if enough folks pitch in, recycling should pay off for everyone. It is good business. Pitting business against the environment is a lose-lose situation – everyone suffers.
Commercial factories and processing plants save masses of cash on energy and extraction systems when they use recycled materials rather than virgin resources. They also make sure that basic resources don’t become a scanty commodity, keeping demand and costs down and making sure that their business can continue for years to come. One person can contribute. Many of us think this is true with recycling, too but the reality is that small acts of recycling make a giant difference.

Bucks USA economic trends – Green technology
Journalism Development
The impression created by the media over years has been held with mixed feelings. Whereas some media corporate world are known to have positively helped transform societies politically, economically, culturally and technologically; some other have only torn the world apart through negative reporting that supports aggressive confrontation, glorifying terror activities to make eye-catching headlines with selfishly money motive.
Similarly, the aggressive, corrupt and oppressive groups and individuals (religiously, politically or economically) have been glorified in the way that sustains situation that steadily extinct some societies.
Their content hardly provided or suggested solutions to alarm-triggering headlines. And much of the media activities have lacked an element of social responsibility that is tangible to give a voice to the voiceless and direct transformative opportunities to the poor, disabled and other disadvantaged groups
Journaling is a key communication tool. All organisms by nature communicate either verbally or non-verbally, yet attempting to make sense of whatever cues that are exchanged or evaluated.
True, we tend to be evaluative of one another whilst trying to figure out what intentions the other party could have towards you. The aim can be to help measure up the relationship that possibly could be developed, whether health or not.
Of course, in certain encounters some people could be threatened, suspicious, lack confidence, defensively withdraw or get on well in a healthy and rewarding relationship. This, indeed, is how communities can influence attitudes and behavior towards one another. That way, we could manage, control and direct directs and behavior. What a powerful tool a pen can be!
But success through journaling it self needs a period of training and practical experience, such that we can communicate to effectively make or unmake relationships or evolve life through the aspects of observing, reading and listening to words and actions of others and things.
The primary motivators to writing is the element of having an opinion yet unique. As part of research steps, one would be required to publish a final report or summarized article from the investigations, results and analyses carried out. Other researchers or students would want to review literature about statements pending investigation. From their successes, investigators either get awards or promotion.
Through practical experience, some people make careers out of their abilities and skills to communicate effectively as writers, as advertising agents, as interpreters and, as counselors or therapists.
Secondary employment too could be provided by journalism like driving, distribution, sale or retailing, legal advising et cetera. Eventually, those associated to it could become social icons or global media giants.
On the other hand, journaling could have important health benefits as stress reliever. By writing about one’s traumatic experience, sufferer could drop so much mental toxins off him or her.
And, at the same time it would help improve on analytical and problem-solving skills crucial in successful dealing with the ever emerging challenges encountered in day-to-day life.
From the natural or ecological sense, journaling or communication significantly help to connect different elements of the eco-system -through the principles of interconnectivity and interdependence.
And through media, we can help improve the dangerous global situations as nuclear conflicts, to make the world a better place for everyone to live in. But this would only be so if we formed a common objective in solidarity to it (non-violence) under the principle of conscious non-violence through tolerance and respect for divergent views.

How to Address Contaminated Land Issues
How to Address Contaminated Land Issues
Under the relevant European Directives, an Environmental Statement is the formal product of an Environmental Impact Assessment. Environmental Statements are often organised in a way that describes the environmental baseline, mitigation and effects for each type of environmental receptors: ecology, water resources, archaeological resources, human beings etcetera. Contaminated land is often managed in the same ways as the various environmental receptor groups, although it is principally a cause of impacts rather than a receptor. It also often refers to a pre-existing condition and its damaging effect is on a variety of different receptors such as human health, structures and buildings, surface water features, groundwater features and ecology. This often means that land contamination specialists struggle with integrating the issue in a logical manner in an Environmental Statement. Sticking to the structured approach of an environmental statement is essential to ensure a clear description of the existing environmental condition, the potential impacts and the actions taken to avoid, minimise, offset or manage the impacts. This article is based on UK practice and legislation, although fundamentally the issues should be similar within other contexts.
Contaminated land is in many countries considered on a source-pathway-receptor basis. This is important to understand the impact land development can have on the issue of contaminated land. Development can interfere with any of these three elements. It can introduce sensitive receptors by changing the use of land, for instance by building new residential units on a site that was previously used for heavy industry. New pathways linking pre-existing contamination with an existing receptor can be formed, for instance when piling through a non-permeable layer connecting a layer of contaminated soils with a deep aquifer. Finally by introducing pollutants on the site a development project can introduce a potential source of contamination.
The second element to consider is the structured approach of an environmental statement. Apart from the introductory and procedural elements described in the environmental statement, a good environmental statement comprised the following sections:
- environmental baseline conditions
- potential environmental impacts
- mitigating measures
- residual environmental impacts
There should be a logical relation between the different sections. Any receptor that is affected and described in the section about the potential impacts and effects should have been introduced in the section describing the baseline. Any material impact should be assigned a mitigation or management action etc. Implementing this structure allows a clear description and understanding of the environmental impacts and the way it will be managed.
Applying these principles to contaminated land will result in a baseline condition section that describes the current sensitive receptors that are present within the potential sphere of influence of the development, the sensitivity and importance of these receptors, the presence of any pre-existing contamination and the presence of actual and potential pathways. The next section, potential environmental impacts or effects, first considers the impacts that the development will have in terms of the introduction (or removal) of sensitive receptors and the creation of new pathways between existing and potential pollution sources and receptors. In addition this section will describe the potential environmental impacts that are associated with the introduction of new sources of contamination. In the third section, mitigating measures, a description of the actions to mitigate each of the impacts that may occur should be provided. Finally a statement of the residual impact of the development is provided in the last section: residual environmental impacts.

Global Warming. Are Tsunami’s Being Caused?
Global Warming. Are Tsunami’s Being Caused?
Throughout the history of our planet it has endured a constantly changing climate. It endured an ice age and has also experienced long periods of heat. But over the last two hundred years, give or take, the temperature of our planet has been steadily increasing. This change in the climate on earth is known as global warming, and global warming is the direct result of the industrial revolution.
Because of the industrial revolution, people are constantly burning fossil fuels such as oil and coal. But by burning these fuels dangerous greenhouse gases like carbon dioxide (CO2) are then released into the earth’s atmosphere. These gases block heat rising from the earth from being able to escape into space. The same basic function that glass panels on greenhouses have, hence the name. Our burning of fossil fuels causes more than three quarters of all carbon dioxide emissions. Power plants and other stationary sources contribute more than half of that amount.
Along with increasing CO2 emissions, deforestation is on the increase as well. This is disastrous, because trees recycle CO2 and release oxygen back into the atmosphere. Because of the rise in deforestation levels the fossil fuels we burn are seriously jeopardizing our planet. We know that global warming is the cause of glaciers getting smaller and for the rise in sea levels. Plants and animals show clear and undeniable signs that they are affected in many different ways. Earth is experiencing longer seasons which results in rivers and lakes freezing later than usual and melting sooner. Without a doubt, global warming causes many changes and affects our planet in many ways but can it also cause a tsunami?
Nobody will ever forget the utter destruction, grief and loss left behind after the huge tsunami that hit parts of Asia on December 26th, 2004. Hundreds of thousands of people were killed, injured and traumatized. The areas it hit were left completely destroyed.
Generally speaking a tsunami is made up of a series of waves. More often than not the first one is the mildest. Prior to the arrival of the first wave, the shoreline recedes dramatically and often leaves the ocean floor exposed. They mostly occur where the water is shallow but they can also occur around coastal areas. In deep water a tsunami appears as a big wave and nothing more. In shallow water this is not the case. The wave can reach as high as one hundred metres, although, in all honesty, this is not at all common.
We know that tsunami’s can be caused by an earthquake, but this is not the only cause. They can also be caused through volcanic eruptions and landslides. Another cause is if a large amount of water is somehow displaced, such as when meteors happen to fall into large bodies of water. Tsunami’s are caused by events that can be, and are, affected by global warming, however global warming itself does not directly trigger the formation of a tsunami. Basically, it is an indirect cause.
One thing is certain, global warming is not a myth as some suggest. The planet is displaying clear signs that we dare not ignore.
