My current event is on Deep-sea life that is being threatened by global warming. Since this topic is a new study; dating back to October 5, 2012. There isn’t really any history on this particular problem. Scientist and Oceanographers have tried a couple of ways to stop such a crime from happening. They have gotten some of the close to being extinct organisms, to supervised habitats, to ensure that they will not become extinct. Also they are going to go in a deeper research on this particular problem. Since warmer waters produce less food and makes the organism’s metabolism faster, scientist could feed/put more food in the ocean. But this solution is not much of a solution considering the fact that there is to many animals, to many large bodies of water, and not enough food to completely fix the problem at hand. The changes in the climate and global warming can possibly change the temperature and food availability in the future. Causing a widespread extinction of the deep ocean organisms. If the environmental changes occur faster than deep-sea organisms can respond, by shifting their ranges or adapting to new conditions, then these same organisms will die. Causing extinction of certain organisms.

Water pollution is a reoccurring problem all over the earth, causing many sicknesses for animals and humans. The biggest example of water pollution is in Kashmir, India. In Kashmir the fish are beginning to die off very quickly, scientist think if the water isn’t treated the fish will soon be extinct. The water in Kashmir is heavily polluted with herbicides, pesticides, and fertilizers that are being dumped into the waters. The chemicals also run-off into the water supply from factories and farms, these types of dumpings also happen in North Carolina. A recent survey conducted showed that over 40 million liters of untreated liquid waste from Srinagar city alone, as well as 350 metric tons of solid waste get dumped into Kashmir’s bodies of water.
ReplyDeleteSince the discovery of the many water pollution cases harming humans and rare species of animals many countries and states are creating laws against littering, dumping chemicals and accelerated deforestation. Many places, like Greensboro, plant a lot of trees and small plants around bodies of water to catch the runoff before it reaches the water. This is a very great idea because when the water is soaked through the soil it is cleaned naturally and it isn’t bad for the soil.
The scientists think that as long as there isn’t any chemical run-off or dumping of chemicals the water should stay safe and clean.

ReplyDeleteThe amount of trash on this earth is becoming very serious. We are running out of materials to make this trash and we are also running out of room to put the trash. Each person throws away about 4.5 pounds everyday. the United States has only 5% of the human population, but throws away 1/3 of all earths trash. The cause of the black plague was trash. the trash that was on the streets attracted rats which carried diseases that caused this plague. Garbage used to be put into the wetlands which emptied out into rivers and caused a flammable gas called methane. People that throw there trash on the streets or water systems like cups,plastic, bags etc. think that just throwing little things like that away is no problem, but it is. Stray animals on the street that are very hungry will eat anything that looks like food to them and the trash could choke them. Also plastic bags can get stuck to animals and suffocate them.
ReplyDeleteWe are starting to recognize these problems and taking action like recycling and not throwing everything away. In 1995 there was a law that made trash dumps fence there area so the trash could not get into the rest of the environment. Also the government made trash dumps get gas monitors so they can see if dangerous gases are getting high.
If people keep throwing away the trash like they do there will be no where to put the trash and it could cause another black plague or some other serious problems.
My current event is on how drills in Antarctica have reached an under-ice lake. On Sunday January 2, 2013 scientist's drills detected a change in pressure showing that they had reached water. The body of water they had reached was Lake Whillans which is a body of water buried almost 1K under the ice. The scientist on the Whillans project used a 30 cm hot-water drill to drill the hole down to reach the water. The purpose of a whole that big is so that they can lower sampling tools and sensors down to the lake. One of the main reasons they're doing this project is to see if there is any habitats of some kind under the ice to see if there is any possible life on other planets in the solar system with the same kind of icy climate. Enceladus, which orbits Saturn, also has large bodies of water under its thick icy exterior.
ReplyDeleteMy topic “non-renewable resources” has been a problem since the Industrial Age. This has been a problem due to the mass consumption of these resources. These resources include metal ores, fossil fuels, nuclear power, and some aquifers. These sources can not be renewed by nature except fossil fuels, which take millions of years to produce. If this constant consumption continues, the Earth will run out of these resources sooner than you think. Scientists predict that by 2100 the Earth will be exhausted of all nonrenewable resources.. Several attempts have been made to combat this problem. Recycling is one of the top ways to prevent the waste of resources. By reusing the resources we have, we can save our resources for the future. Using less energy also slows done the use of the non-renewable resources. Lastly using alternative energies also saves the resources. Powers like electricity, wood, hydro-power, and solar. Doing all of this will prevent the planet’s resources from being exhausted. Generations to come will have resources to make a better tomorrow.
ReplyDeleteThe current event that I have chosen to write about for this week’s blog is on the Great Barrier Reef and how over half of its coral has slowly but surely been disappearing over the past twenty-seven years. Although this has been an ongoing problem for the past twenty-seven years, oceanographers have just recently discovered the problem using a specialized reef monitoring program. Of the already deteriorated coral, 48% of the coral loss was due to storm damage, 42% of the loss was due to crown of thorns starfish, and the other 10% was due to bleaching of the reef. The problem was discovered by a new comprehensive reef monitoring program by the Australian Institute of Marine Science (AIMS). The special monitoring program that discovered the coral loss has been used frequently for the past twenty-eight years and around fifty million dollars has been invested into its use.
ReplyDeleteOceanographers are worried that if this problem continues, potential serious permanent damages will be made and the coral will never be replenished. If the coral does not begin to grow back regularly soon, then because of natural causes it will never have a chance at fully flourishing ever again. Recent studies have shown that the coral’s recovery time would take ten to twenty years with the absence of crown of thorns starfish, not a fast recovery time, but a potential goal.
It has been said that although storms and ocean warming cannot be stopped from damaging the reef, the crown of thorns starfish species’ impact can be reduced by close studies of their habits and life cycles. Water quality is a large factor in the life expectancy of these aquatic pests, and scientists are doing everything in their power to stop these starfish from creating any more damage to the Great Barrier Reef.
Climate Change Affects Biodiversity. Throughout Earths history the climate has always changed with ecosystems and species coming and going rapid climate change affects ecosystems and species ability to adapt and so biodiversity loss increases. From a human point of view the rapid climate change and accelerating biodiversity loss risks a major change in the food chain which we depend on. Water sources may change and disappear,medicines and other resources we rely on may be harder to get because plants and places they are gotten from may disappear. Some species may benefit from climate change including, from a human point of view, an increase in diseases and pests but the rapid nature of the change suggests that most species will not find it as beneficial as most will not be able to adapt.
ReplyDeleteThe current event that I am writing about is bio-ethanol fuel. Now before I start telling you about the problem, I will tell you exactly what bio-ethanol fuel is. Biofuel is a type of fuel whose energy is derived from biological carbon fixation. This is the process of releasing energy through carbon molecules. The biofuel is mainly made up of corn and corn stocks. They use this and change it to an alcohol, through fermentation. This then turns the corn into ethanol. The problem with this is that, although we are not drilling for as much oil, we are taking away a big food source for humans and animals. Also, ethanol is bad for vehicle engines because it corrodes the seals inside the engine. Many scientists have been arguing over that past months about whether or not this is better or worse for the human race. Some scientists have said that ethanol can also emit more harmful gases into the atmosphere. If the production of ethanol is continued and massively produced, America and many other countries could lose a high percentage of their corn crops due to ethanol. And although gas prices may lower due to this, food prices may go higher because of the usage of corn. Think of your everyday food products with corn and corn syrup. So America may benefit in some ways from the ethanol fuel because they wont have to buy as much from other countries, but in other areas of America's imports and exports, profits may fall.
ReplyDeletedestruction of the rain forest
ReplyDeleteThe current event I am writing about is about destruction of the rain forest. This problem has been going on for a while. More than half of the rain forests have already been cleared away. The forests are being cleared mainly by timber, palm oil, soybean, and mining companies. 6.3 million hectares of rain forest are disappearing every year!
ReplyDeleteThings done to stop this problem are building national parks and reservations. There are also many charities with supporters donating money to help prevent damage to the rain forest. A thing that anybody can do to help is to recycle, and reduce waste. Every recycled can or bottle helps! Supporters can also sponsor their own acre of rain forest.
The history begins when our ancestors were burning and hacking down forests as soon as they learned how to use fire and make sharp tools, at least 250,000 years ago. The process accelerated with the arrival of agriculture around 11,000 years ago. Forests were cleared to make arable land and pasture.
Destroying the rain forest will endanger all of the people, animals, and plants that live there. Many animals will go extinct. When the trees are cut down, the soil easily erodes and can cause landslides. It can also cause flooding and global temperature change.
Ocean circulation changing by the ozone thinning .
ReplyDeleteA hole in the Antarctic ozone layer has changed the way that waters in the southern oceans mix, a situation that has the potential to alter the amount of CO2 in the atmosphere and eventually could have an impact on global climate change. subtropical intermediate waters in the southern oceans have become "younger" as the up welling, circumpolar waters have gotten "older" ,changes that are consistent with the fact that surface winds have strengthened as the ozone layer has thinned.This matters because the southern oceans play an important role in the uptake of heat and carbon dioxide, so any changes in southern ocean circulation have the potential to change the global climate.
ReplyDeletemeasurements taken from the early 1990's to the mid-to-late 2000's of the amount of a chemical compound known as chlorofluorocarbon-12 or CFC-12. ( used in hair spray , and air conditioning systems ) From those ocean measurements, Waugh's team was able to infer changes in how rapidly surface waters have mixed into the depths of the southern oceans. Because they knew that concentrations of CFC's at the ocean surface increased in tandem with those in the atmosphere, they were able to surmise that the higher the concentration of CFC-12 deeper in the ocean, the more recently those waters were at the surface. because of this situation , it can cause global weird climate changes frequently.
My topic was 'Acid Rain' which can also be called 'Acid Precipitation' because it can fall in any form of precipitation; not just rain. Acid rain comes from pollution, sulfur dioxide, fossil fuels, and nitrogen oxide. This rain was first discovered during the Industrial Revolution in 1852 by Robert Angus Smith. Nobody really realized what a problem it was until the 1960's. Since the 1970s, the government has been trying to get rid or lower the amount of acid rain. They did this by reducing the amount of sulfur dioxide being released into the atmosphere. This has actually helped. Acid rain may be a lot more threatening to the atmosphere than you think -- it causes animals to die off (especially fish that actually live in water), trees to also die off, buildings, bridges, and other structures to decompose, etc. In the future, it could cause certain types of animals to become completely extinct. If we keep losing trees to acid rain, the oxygen levels will go down. Scientists, the government, and others are still trying to find a way to reduce acid rain even more or completely get rid of it.
ReplyDeleteThe Arctic Cylone of August 2012 arose in siberia on August 2 and crossed the Arctic Ocean to Canda, Lasting an unsusually long 13 days. The cylone hit a pressure minimum of 966 millibars on August 6, the lowest ever recorded for an Arctic storm. The stronger the pressure gradient, or difference in pressure, the stronger the winds associated with a storm. After the storm, which was in equal strength to a hurricane, tore across the Arctic, scientist have wondered whether its winds and waves were a guilty party in the disappearing Arctic sea ice. So the question is, quilty, or not quilty? To solve the mystery, climate scientists performed the equivalent of a forensic exam: They ran a computer simulation of last summer's weatherand comparedit against asecond scenario that was identical, except that there was no cyclone. Though the storm had a huge impact on sea ice while it passed, within two weeks, the effect diminished. So, quilty or not quilty? The verdict.. Not quilty.
ReplyDeleteScientists conclude the cyclone reduced the final September ice extend by almost 60,00 square miles, and in additional 5 percent. However, they point out that 2012's record loss was 18 percentgreater than the previous low, set in 2007.
Coral-Killing Starfish Responsible for Decimating Entire Coral Reefs
ReplyDeleteThe Crown-of-thorns starfish (Acanthaster planci) is the greatest natural threat to any reef-building corals. Periodically, out breaks of Acanthaster planci occur. It has decimated entire reefs in the French Polynesia since 2004. Since these populations explosions, the rate of living coral cover in ocean depths and lagoons, has dropped from 50% (healthy reef) to under 5% in 2009 alone. The archipelago has one of the most intense out breaks ever recorded. It's been suffering through a population explosion of Acanthaster Planci since 2004.The out breaks of these predatory starfish originated from the Austral and Leeward Islands. Over time it spread to Tahiti and Moorea. There are about a dozen stations around the island of Moorea, where scientists were able to make observations about the dynamics of infestation populations.
Although the reasons for these out breaks are unknown, scientists have a few ideas. In Austrailia, which is also being plagued by this aquatic pests, invasions occur after years with high rain falls. These high rainfalls bring nutrients into the waters from human activities. Though in Polynesia, they don't have the anthropic influence seems too low and localised to explain such an outbreak of the starfish.
With all the destruction that the starfish are causing, it's estimated that the ecosystem with need at least a decade to be restored to its original state.
Even if you live 1,000 miles from the nearest and largest city, it can affect your weather. Heat generated from human activities can alter the jet stream and other atmospheric systems. The heat from cars and buildings can cause winter warming in part of North America and Northeast Asia.
ReplyDeleteTemperatures have risen about 1.8 degrees Fahrenheit in some areas, according to the research by scientists at the Scripps Institution of Oceanography, University of California (San Diego), Florida State University, and the National Center for Atmospheric Research.
Worldwide, the temperature has increased about 0.2 degrees Fahrenheit.
Us burning these fossil fuels is not only changing the temperature, but is also releasing greenhouse gases into the atmosphere.
Increases in extreme rainfall linked to global warming.
ReplyDeleteResearchers have evaluated the association between extreme rainfall and atmospheric temperatures at more than 8000 weather gauging stations around the world. As explained by Dr. Seth Westra, the result of rainfall extremes are increasing on average globally. They show that there is a 7% increase in extreme rainfall intensity for every degree increase in global atmospheric temperature. Assuming an increase in global average temperature by 3 to 5 degrees Celsius by the end of the 21st century, this could mean very substantial increases in rainfall intensity as a result of climate change. Scientists’ results show that rainfall extremes were increasing over this period and appear to be linked to the increase in global temperature of nearly a degree which also took place over this time. If extreme rainfall events continue to intensify, we can expect to see floods occurring more frequently around the world. The strongest increases occurred in the tropical countries, although some level in increase seems to be taking place at the majority of weather gauging stations. Most of these tropical countries are very poor and therefore not able to adapt to the increased risk of flooding, which puts them in a larger threat of devastation.

ReplyDeleteEarth Warming Faster Than Expected
ReplyDeleteBy 2050, global average temperature could be between 1.4°C and 3°C warmer than it was just a couple of decades ago, according to a new study that seeks to address the largest sources of uncertainty in current climate models. That's substantially higher than estimates produced by other climate analyses, suggesting that Earth's climate could warm much more quickly than previously thought.
ReplyDeleteMany factors affect global and regional climate, including planet-warming "greenhouse" gases, solar activity, light-scattering atmospheric pollutants, and heat transfer among the land, sea, and air, to name just a few. There are so many influences to consider that it makes determining the effect of any one factor—despite years and sometimes decades of measurements—difficult.
Daniel Rowlands, a climate scientist at the University of Oxford in the United Kingdom, and his colleagues took a stab at addressing the largest sources of short-term climate uncertainty by modifying a version of one climate model used by the United Kingdom's meteorological agency. In their study, the researchers tweaked the parameters that influence three factors in the model: the sensitivity of climate to changes in the concentration of carbon dioxide in the atmosphere, the rate at which oceans absorb heat from the atmosphere, and the amount of cooling from light-scattering aerosols in the atmosphere.
Bioinspired Fibers Change Colors When Being Stretched
ReplyDeleteA team of materials scientists at Harvard University and the University of Exeter, UK, made a new fiber that changes color when its being stretched. Inspired by nature, the researchers identified and replicated the unique structural elements that create the bright iridescent blue color of a tropical plant’s fruit.
The fibers’ superior mechanical properties, combined with their demonstrated color brilliance and tunability, make them very versatile. For example, the fibers can be wound to coat complex shapes. Because the fibers change color under strain, the technology could lend itself to smart sports textiles that change color in areas of muscle tension, or that sense when an object is placed under strain as a result of heat. :)
Greenhouse Gases and Climate Change
ReplyDeleteMany chemical compounds found in the Earth’s atmosphere act as “greenhouse gases.” These gases allow sunlight to enter the atmosphere freely. When sunlight strikes the Earth’s surface, some of it is reflected back towards space as infrared radiation (heat). Greenhouse gases absorb this infrared radiation and trap the heat in the atmosphere. Over time, the amount of energy sent from the sun to the Earth’s surface should be about the same as the amount of energy radiated back into space, leaving the temperature of the Earth’s surface consistent. Levels of several important greenhouse gases have increased by about 25 percent in the past 20 years, about three-quarters of human-made carbon dioxide emissions were from burning fossil fuels.
US citizens have the worst impact on global warming compared with every other country. US citizens account for only 5% of the world’s population, but 25% or more of its total resource consumption and greenhouse gas emissions. To help reverse global warming, we must take personal actions. Some steps we can take are by using fluorescent light bulbs, solar energy, electric or hybrid cars, planting trees at home, saving clean water, reducing trash at home, and much more.
There are many possible effects of global warming if steps to reduce it are not taken. Some effects are:
-The spread of disease: As northern countries become warmer, disease carrying insects migrate north, bringing plague and disease with them.
-Warmer waters and more hurricanes: As the temperature of oceans rise, so will the probability of more frequent and stronger hurricanes.
-More floods
-More wildfires: Dry areas of land that are already open to wildfires are likely to be consumed by even more frequent and destructive fires.
-Death by smog: A powerful combination of vehicular fumes, ground-level ozone, airborne industrial pollution and the filthy hot air associated with heat waves, smog represents an immediate health threat to those living in urban areas.
-More dangerous thunderstorms: A consequence of the increased amounts of humid air generated by global warming is that more thunderstorms will be triggered.
-Death of ocean life.
My topic is the Earth's Energy crisis. The impact of energy on human life is probably only second to agriculture and forestry. That having been said, the negative impact that energy, as a source, has on the environment is getting out of hand. Energy of any kind, may it be thermal, hydro, nuclear or electric has led to several environmental concerns. Where earlier the concerns were restricted to the local area, the issues have now become global. Energy and the activities related to energy production lead to hazards of some form or the other. Extraction of raw material for production, transportation, and the conversion to usable forms of resources have a harmful effect. Along with that, it has also led to concerns like acid rain, the greenhouse effect as well as global warming. Some Renewable energy sources are,solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass and biofuel.
ReplyDeleteMy Topic Is Waste Management,
ReplyDeleteWastes can be of several kinds industrial, nuclear, chemical, domestic, and each can lead to environmental degradation. From excessive plastic used at home to the radioactive waste produced by nuclear plants, the impact can be disastrous.
Not only are these wastes harmful on their own, but the techniques of waste management and disposal adds to this problem multiple . Emissions from industries as well as toxic by-products like mercury, crude oil, plastic and lead are not properly disposed of. They are dumped into the oceans and soil, thus leading to disastrous impacts on all life forms.
Of these, oil spills have become another major concern. These wastes lead to the destruction of natural habitats of both plants and animals and other species as well, in both land and water. They therefore make the environment toxic. Along with increasing the risk of extinction of several species, it also leads to other health concerns such as the development of fatal diseases like cancer and lead poisoning.
These are some of the current environmental issues we are facing today. With an effort from each individual, we can only hope to save our planet from being destroyed.
Iceberg Dangers
ReplyDeleteIcebergs are pieces of ice that formed on land and float in an ocean or lake. Icebergs come in all shapes and sizes, from ice-cube-sized chunks to ice islands the size of a small country. The term “iceberg” refers to chunks of ice larger than 5 meters (16 feet) across. Smaller icebergs, known as bergy bits and growlers, can be especially dangerous for ships because they are harder to spot. The North Atlantic and the cold waters surrounding Antarctica are home to most of the icebergs on Earth.
All icebergs are dangerous to shipping but depending on size, shape, and location some icebergs can be more troublesome than others. Obviously, icebergs nearest the Atlantic shipping lanes are of greatest concern to mariners. Large icebergs, because of their great mass, can inflict the most damage on a ship. However, they are usually easy to detect on a ship's radar and therefore can be avoided. On the other hand, the smaller an iceberg, the harder it is for ships to detect and avoid. For example, many growlers or bergy bits are mostly submerged and are about the size a small vessel. These "hidden" icebergs can cause a significant amount of damage.
My current event about the Mercury poisoning in Nigeria, Africa. Mercury is a heavy silvery-white colored metal that is a liquid when in ordinary temperatures. The Mercury poisoning in Nigeria is the result of Illegal Artisanal gold mining. This is something that is very common in these areas, so there fore the result of the outbreak is due to prolonged exposure of the hazardous chemicals. The symptoms are convulsions, fevers, and seizures. When medical attention was received doctors thought it was a common disease, but no one responded to the antibiotics.They suddenly realized that it must have had something to do with the increased amount of gold mining, which lead them to the theory of lead poisoning. The government has become aware of the issue and has reduced the time they may work in the mines. The government has also warned the locals about the consequences of living near mines where they are more susceptible to inhaling or coming into contact with with the dust. There is a treatment for people who have been contaminated, this is called Chelation therapy. However, everyone is still concerned that this could get out of hand and Mercury poisoning could be taken to a whole new level.
ReplyDeleteMine is on The endangered species of Tigers.....
ReplyDeleteIn India tigers are in trouble again and it may be the last
time. Wildlife conservation experts now believe that India
has so few tigers left, and they have so little room to
maneuver, that populations have no recourse but to
dwindle to extinction. Alan Rabinowitz, president and CEO
of the Panthera Foundation, has championed tigers,
jaguars, leopards and pumas and worked to preserve their
habitats, from South America to Southeast Asia.
Habitat loss has been a huge factor. The tiger's range is in
Asia, an area with the world's oldest cultures, the world's
most populated countries, for many decades the world's
most tumultuous regions engulfed in war. The tiger had to
try to sustain itself throughout all of this, and consequently
it lost huge areas of habitat, and more importantly, what
people weren't looking at, what was happening to the
tigers' food. Even when tigers weren't being hunted or
were being protected, nobody was protecting their food
source, which was a major food source for the local people
also: wild pigs, samba deer, that kind of thing.
My current event is about how wildfires effect the lives of living things. The harmful substances produced by wildfires is threatening the health of people and especially those with asthma and other lung diseases. A single fire alone can burn over 1000 km2 trees. The Ministry of Environment watches to see that the pollutants do not become too extreme. Wildfires have been going on for hundreds of years.Researchers from British Columbia Centre for Disease Control and University of British Columbia use records to find out if forest fires have caused an increase in use of short acting beta agonist (SABA) such as salbutamol. Salbutamol sulphate is what is used to relieve the symptoms of asthma and other lung diseases. The inhalant was discovered as being needed up to 4 days after the wildfire. It is hard to control or prevent a wildfire, also known as a natural disaster.
ReplyDeleteAir pollution is a major factor in the problem of global warming. When people think of global warming they point fingers at carbon dioxide at the main culprit. Actually humans are the ones to be pointed at. For the past 150 years we have polluted the air with a machines that produce large amounts of greenhouse gases and carbon dioxide and throwing our trash out in the environment. Fortunately we are coming to our senses and making efforts such as recycling, enforcing the Kyoto Protocal which is an agreement that countries will cut back on their emission on carbon dioxde, and putting higher taxes on gasoline so people and companies will have better reasons to save more fossil fuels and pollute less. Hopefully, this will clean up our act before global warming takes it toll on us and we acculmulate major issues such as increased sea levels, because of the melted glaciers and the sinking of land. Im sorry that this is in late
