Fossil Fuels | Environmental Center | University of Colorado Boulder Fossil fuels are energy resources like coal, oil, and natural gas that were formed after dead plants and animals were buried and exposed to extreme pressure and temperature millions of years ago. Above image provided courtesy of the U.S. Energy Information Administration Oil Oil is the energy source of our time. However, the environment is paying a serious price for our unbridled consumption of fossil fuels and our climate is warming at a rate that may cause irreversible consequences. Dependence on oil as an energy source is a real danger to our national security, our environment and our economy. If you want to learn more about oil and how it's used and make, take a look at the US Energy Energy Information Administration. Coal Of all the coal used in the United States, 92% is burned to generate electricity. So, what's the big deal? Natural Gas A quarter of the U.S. energy consumption comes from natural gas, a mixture of mostly methane and a smaller amount of other hydrocarbons.
Animation: Human Population Growth Over All of History Imagine that for every million people on Earth, there was a single dot on a map. In total, that would be about 7,600 dots – representing today’s global population of 7.6 billion. But, what if we went back in time, and watched those dots accumulate over human history? When and where do the first dots appear, and when does population growth ramp up to get to the billions of people that are alive today? The History of Population Growth Today’s animation comes from the American Museum of Natural History, and it shows over 200,000 years of population growth and the major events along the way. If you consider yourself on the more impatient side of things, we suggest starting at 1:50 which will zoom you to 400 AD – the time of India’s Golden Age. It took 200,000 years of human history to get to one billion people – and just 200 years to reach seven billion. Key Population Moments Agriculture The impact of farming cannot be emphasized enough.

Bivariate Sampling Statistics This site is a part of the JavaScript E-labs learning objects for decision making. Other JavaScript in this series are categorized under different areas of applications in the MENU section on this page. Enter (by replacing) your up-to-42 two samples paired-data sets where measurements are made jointly on two random variables (X, Y) per subject, and then click the Calculate button. Blank boxes are not included in the calculations but zeros are. In entering your data to move from cell to cell in the data-matrix use the Tab key not arrow or enter keys. Risk Assessment Process: Clearly, different subjective probability models are plausible they can give quite different answers. Cov(X, Y) / Var (X) is called the beta of the random variable X with respect to Y. Given you wish to invest $12,000 over one period (with the same length of time), how do you invest for the optimal strategy? Using the JavaScript we obtain: Beta (Currencies) = -0.4578313, and Beta (Gold) = -1.9

Fossil fuels are made up of plant and animal matter. When plants and animals died, their bodies decomposed and were buried under layers of earth. Fossil Fuel Energy - Oil Oil is a thick, black, gooey liquid also called petroleum.

After the stinky chemical is added, the natural gas is sent through underground pipes which go to your home so you can cook food and heat your house. Fossil Fuel Energy - Coal Coal comes in several different forms from hard black rocks (that's the kind you get in your stocking at Christmas) to soft brown dirt. Courtesy of Peabody Energy, Inc.

These charts show how migration is changing our cities In 2015, over a billion people migrated: 244 million went abroad and 763 million moved within their home country. Some boarded planes to start a new job in another country. Some risked their lives in overcrowded boats, fleeing war or famine. And others left the countryside in search of jobs and a better quality of life. What the vast majority have in common is that they ended up moving to a city. A new report by the World Economic Forum looks at these patterns of migration and how they affect the world’s cities. Where are migrants moving to? The numbers of migrants are growing. Image: World Economic Forum Nearly one in five (19%) of the world's total migrants went to live in the United States. However, when you look at the number of migrants as a proportion of the population, countries in the Middle East far outstrip any other. Migrants tend to head to global cities. Of the nearly 7 million foreign-born people living in Canada, almost half (46%) live in Toronto. Emerging centres of growth

Eurostat Eurostat est une direction générale de la Commission européenne chargée de l'information statistique à l'échelle communautaire. Elle a pour rôle de produire les statistiques officielles de l'Union européenne, principalement en collectant, harmonisant et agrégeant les données publiées par les instituts nationaux de statistiques des pays membres de l'Union européenne, des pays candidats à l'adhésion et des pays de l'Association européenne de libre-échange. Historique[modifier | modifier le code] Eurostat a commencé à fonctionner en 1953 pour répondre aux besoins de la CECA : l'article 47 du traité autorisait la communauté à collecter des statistiques, indispensables à sa bonne marche. Au début des années 2000, une polémique (en) a porté sur d'éventuels détournements de fonds. En 2010, la révélation de l'incapacité d'Eurostat à déceler les falsifications des comptes publics de la Grèce pose la question de ses compétences et de son mode de fonctionnement. Il est divisé en neuf thèmes :
