Over the past three years, satellites have been mapping the upper part of the Earth magnetic field by collecting data. Most of the Earth magnetic field is generated at a depth around 3000 km by the movement of molten iron in the outer core and the new map shows detailed variations caused by geological structures in Earth's crust. Around the city of Bangui, the magnetic field is significantly sharper and stronger. Scientists speculate that it may be the result of a meteorite impact there some 540 million years ago.
Swarm is a European Space Agency mission to study the Earth's magnetic field. I think having an agency specifically to study the earths magnetic fields to better understand earths past is extremely beneficial for the science community.
CO2 emissions plays a large role in environmental impacts. Coal and oil mines are causing temperatures to peak across the globe as fossil fuels continue to burn and release CO2. In order for the environment to be sustained, energy must be renewable, but utilized at an affordable price for the consumers.
Coal is is accessible since it is easy to mine, store, and convert to electricity. This makes coal electricity one of the cheapest sources in the world. However, coal mining is dangerous, and coal burning produces large amounts of pollutants. In fact, burning coal produces about half of all CO2 emissions. Overall, coal is cheap but has negative environmental impacts.
Due to uranium's power as an energy source, nuclear energy is cheaper than coal. Nuclear is the most powerful energy source and is 20 percent of the United State's energy with 120,000 times more power than coal has. Even though Nuclear energy is cheap, creating power plants for them is expensive and worries many people if the event of one exploding was to occur.
Air pollution can alter the effectiveness of antibiotics and increases the potential of disease, new study reveals
Research at the University of Leicester has explored the impact of black carbon on bacteria in the respiratory tract. The study has important implications for the treatment of infectious diseases, which are known to be increased in areas with high levels of air pollution. A major component of air pollution is black carbon, which is produced through the burning of fossil fuels such as diesel, biofuels, and biomass. The research shows that this pollutant changes the way in which bacteria grow and form communities, which could affect how they survive on the lining of our respiratory tracts and how well they are able to hide from, and fight our immune systems. The research team found that "black carbon alters the antibiotic tolerance of Staphylococcus aureus communities and importantly increases the resistance of communities of Streptococcus pneumoniae to penicillin, the front line treatment of bacterial pneumonia."
During the month of February, the percentage of California still stuck in a drought dropped 22% in a single week, as the wettest winter in decades saw an onslaught of storms deliver record breaking rain across the state. The Chaos that took place over Californian's presidents day weekend can be attributed to a phenomenon scientist call Atmospheric Rivers which are narrow corridors of concentrated moisture suspended in the atmosphere, which can hold up to 15 times more water than the amount that flows through the Mississippi River. These suspended moisture plumes, which can stretch 400 to 600 km wide (250 to 370 miles), have been linked to all seven floods on California's Russian River between 1996 and 2007.
Many people believe that the drought will end this year, which in terms of surface water levels it very well could at the rate we are going, but in terms of ground water, it would take much more water over a long period of time to replenish all the water that has been taken over the past few years. I think that people need to be educated on that matter and still continuing to conserve water.
As 2017 continues to be the wettest year in California for the last 20 years, everybody is completely shocked, and maybe unprepared. With most parts of California hitting an upwards of 15 plus inches of rain this year, lakes and reservoirs are filling up. Many dams are hitting possible flood stage levels. Not all reservoirs have adequate facilities, meaning that they were not ready for this amount of water. This was proven by the failing of the Orville Dam spillway. The huge amount of water and some cost cutting choices when building the dam, the water overflowed over the spillway, and destroyed it.
With Trump and his uneducated administration in office for almost two weeks, the EPA, Environmental Protection Agency, is already beginning to have its important information removed. Environmental work during Obama's administration has been removed such as federal climate change plans, mention of carbon pollution causing climate change, U.S. commitment to the United Nations climate negotiations, and partner page for the Tribal Environmental General Assistance Program (GAP).The EPA website has also been removed of mentions of the United Nations and the Organization for Economic Cooperation and Development, removing the paragraph of U.S's commitment to help.
With Trump, a man who believes Climate Change is nothing more than a "hoax" and Scott Pruit, a man who previously has sued the EPA because its not in the best interest of his businesses now in office I'm afraid nothing will be done about environmental issues. The EPA would be removed completely if it was up to these money hungry imbeciles. EPA information is being removed, and if Americans stay unaware of this, it could potentially allow the EPA to actually be removed.. As an educated american, it is important to stand with the science and try to educated others in efforts to save our planet.
Trump has recently announced his executive order that will carry out his promise of building a wall, ignoring all the negative consequences of such an action. Besides being a giant waste of american money, building a wall will increase greenhouse emissions with the production of cement. Also, wildlife migrations have already been blocked by the construction of fences and walls without environmental protections. In fact, existing fencing has “led to erosion and flooding in border communities along with a roadblock for the natural movement of wildlife across the border.” Building a large wall will only increase these problems. The borderlands have some of the highest diversity of species including many of which are threatened, and a wall will divide the species.
Its only been a couple days so far, but already the Trump presidency is a let down. It would appear that he is only taking america backwards instead of progressing especially in the Environmental issue aspect of things. If things continue going in this direction Trump may take us past the point of no return in Environmental issues.
According to a new study at the University of Washington, One of Alaska’s many abounding freshwater fish class is altering a tact patterns in response to meridian change. This could impact a ecology of northern lakes, that already acutely feel a effects of a changing climate. The information they found showed that stickleback multiply progressing and some-more mostly any deteriorate in response to progressing open ice dissection and longer ice-free summers.
I think that this could potentially be a big issue. Its just proving how bad climate change is, and how its effecting so many different things. If there is a disruption to these alaskan fish it can cause a chain reaction and affect many other species who live in the same habitat due to the fact these fish act as a fertilizer to the water. With out these fish more Environmental issues could arise.
In a recent study, NASA found a correlation between wildfires and drought in Sub Saharan Africa. It's evident that various factors influence these African droughts, both natural and human-caused. However a periodic temperature shift plays a role in the soil being able to retain moisture. The shiny desert soil that reflects sunlight directly back into space, and the capacity for rainfall is diminished.
NASA's senior scientist Charles Ichoku found that "There is a tendency for the net influence of fire to suppress precipitation in northern sub-Saharan Africa." So, for example, in years that had more than average burning during the dry season, measurements of soil moisture, evaporation decreased in the following wet season. Even within dry seasons, the amount of water decreased in areas with humid climates when burning started to become more severe.His results prove a correlation between fires and water cycle indicators, and his evidence found will help other scientist improve climate models.
Around two years ago, Sandia National Laboratories researchers Joe Pratt and Lennie Klebanoff set out to answer this question: Is it possible to build and operate a high-speed passenger ferry solely powered by hydrogen fuel cells? Recently they found their answer and the answer is yes. The groundbreaking study found that it is technically possible to build a high-speed, zero-emission hydrogen-powered ferry. They ran a series of tests where the feasibility of a ferry like this was unknown and it was passed in all aspects.
This is a really big deal, because a zero-emission hydrogen powered ferry could eliminate environmental pollution from ships. Hydrogen-powered ferries do exist, but most are smaller, slower vessels used for tours on lakes and rivers.With hydrogen powered boats upscaling, it means that soon many boats can be ran this way, cutting back on the emissions and pollutants in oceans immensely. I think this is a great concept!
