Is global warming a belief or a real danger? "Make no mistake: without concerted action, the very future of our planet is in peril," says Christine Lagarde, head of the International Monetary Fund. Our Planet Earth is facing a huge threat by global warming due to intensified use of fossil fuels and an increase rate of harmful gases such as carbon dioxide and nitrous oxide. Many scientists believe that climate change is occurring and they provide some scientific evidence to prove this, yet some…

Saturn is the sixth planet from the sun and the second largest planet in the solar system. Saturn is the farthest planet from Earth and not visible to the naked human eye, but it is through a telescope that the planet’s most outstanding features can be seen: Saturn’s rings. Although the other gas giants in the solar system, Jupiter, Uranus and Neptune, also have rings, those of Saturn are without a doubt the most extraordinary. Saturn is a gas giant made up of mostly hydrogen and helium gas,…

(NOx). Indeed, regardless of the combustion process, all involve the release into the air of nitrogen oxides. With the presence of direct sunlight, these compounds are forerunners of the formation of ozone in the lower part of the atmosphere (troposphere). It is to remind that ozone is an oxidant which is harmful to health and the environment. Thanks to its Chemicals business, Total has been able to stabilize NOx emissions from its boilers and its ovens. Numerous efforts are being made in this…

Perhaps the most vital thing to address is the difference between climate and weather, because so many people don 't know the difference. Weather is what happens on a short time scale--from day to day, while climate is more long term, and is the long term trend over hundreds to thousands of years. We are releasing tons of gases and dust particles into the earth 's atmosphere every day, and so the salient question becomes: What type of effect do these gases have on our atmosphere? Most climate…

Human Influences on Global Climate Change The earth has been around for about 4.5 billion years, and the climate has been changing throughout that time period. Most of this climate change is in a sense normal because it is due to small variations in the Earth’s orbit or due to natural influences such as solar changes or volcanic eruptions. Although the occurrence of climate change is relatively settled and accepted, some uncertainty remains as to whether humans and their ecological footprint…

RADIOWAVE OUTDOOR PROPAGATION MODELS General definition: • They are empirical mathematical formulation for the characterization of radio wave propagation as a function of frequency, distance and other conditions. • These models predict the path loss (i.e. the reduction in power density of an electromagnetic wave as it propagates through space or underground) of a transmitter and also the effective coverage area of transmitter. We know that when a signal travels from a wireless channel, it…

1.1 Introduction/ what is Acid Rain? Acid rain, or acid precipitation is a term used to describe any form of precipitation with a pH of less than 5.6. In recent years, the effects of acid rain are being experienced on a global scale with widespread environmental effects. Primarily, acid rain is caused by emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) from the combustion of fossil fuels. However, even pure rainwater is slightly acidic (pH of 5.6-6.5) due to the reaction between H2O…

Have you ever felt that the weather is getting warmer over the years? Have you ever been in a situation where you are enjoying a very sunny day and all of a sudden you are forced to look for shelter because of the sudden drizzle or downpour? Have you ever thought what caused all of these changes to our climate? Remember a time when you actually stopped to question the origins of these sprouting anomalies around you. Can you think of such a moment? All of these situations are becoming more…

hydrologic cycle allows for rain to form and pour down in different areas. Water from oceans, swamps, lakes, rivers are evaporated and turn into water vapor due to the water being heated by the sun or other means. This water vapor rises into the troposphere (where most weather phenomena occur) and cools as it ascends. When it condenses, the water vapor become water droplets that form clouds. Then, precipitation occurs and water droplets fall as rain or cool down even further and become snow.…

Absorb the odours This is where we get to dive into a little bit of odour eliminating voodoo. Although people have their opinions as to why these different methods work, most don’t really know. All that matters is that it works, right? Coffee grounds Place open bowls of coffee grounds in cupboards or places that have lingering smoke smells. Like magic, these grounds will kill odours like that’s what it was made for. Plain charcoal Use charcoal like the coffee grounds. Feel free to buy…
