    Light Pollution Is One of the World’s Biggest Buzzkills…Here’s Why

    Have you ever come home from a long day to find your front door swarmed by flying insects? Or more accurately, your front door’s light? Turns out, that’s more than a minor inconvenience. Light pollution is contributing to worldwide insect decline and that’s actually a huge problem. Insects may seem pesky. They bite and sting us, flutter and scuttle into our houses, swarm around our faces and eat our crops. But actually, of all the insects in the world, only 1% of them are pests responsible for any real damage! And almost all insects play really important roles in our world. For instance, many are pollinators, so they keep ecosystems…

    Socio-ecological Transformation Processes – Professor Perdita Pohle

    One topic our research is about is socio-ecological transformation processes and the acceptance of the local population of these socio-ecological transformation processes in adaptation to climate change. For example, in the landscape, if we increase mais production for biogas, then there is a competition among land use between mais production and food production.

    The Science Behind Climate Change (Documentary)

    What is global warming? How did it start? How will it continue? What will happen to humanity? Will one day we’ll be gone due to our own ignorance? Global Warming is the continuing rise in the average temperature of Earth’s climate system Through the sudden use of factories, gas consuming cars and and other ambitions from fossil fuels the Earth’s temperature has rapidly increased since the beginning of the industrial age Global warming is a natural event but is being majorly contributed to by humans today, the quality of the atmosphere has been irreversibly depleted over time and if nothing is done about it, the Earth will ultimately swelter Americans…

    We Are Duke Environment: A Community of Purpose and Passion

    (happy music) – Hi, I’m Toddi Steelman. Our world today is changing rapidly, and the environmental challenges we face are growing increasingly complex. At the Nicholas School, we’re a community of innovators, doers, dreamers, and disruptors. A community united in our purpose to address these complex challenges and have a positive impact on the world. As a Master of Environmental Management or a Master of Forestry student at the Nic School, you can pursue your passion for exploring complex environmental problems in a real and purposeful way. You will be immersed in a school culture that is academically rigorous and career oriented. You will interact with other students who are…

    Types of air pollution

    In this lecture, we focus most of our attention on air pollution because that is, by far, the most important way in which the energy system impacts human health today. I’m going to talk you about some of the most important airborne pollutants– the so-called criteria air pollutants as defined by the US Environmental Protection Agency. We can divide the list into two categories: direct pollutants and secondary pollutants. Lead, nitrogen oxides or NOx, sulfur dioxide or SOx, and carbon monoxide are direct pollutants, in that they are emitted directly from industrial activities– primarily, the combustion of fossil fuels. Ozone is a secondary air pollutant. There is no significant direct…

    How Entropy Powers The Earth (Big Picture Ep. 4/5)

    The earth receives about 90 petajoules of energy from the sun every second. That’s a lot – enough to satisfy all human energy needs thousands of times over. However, the earth also radiates an equal amount of energy back into space as heat. (An almost equal amount, anyway — the Earth is gradually heating up, but that’s another story.) So if energy in equals energy out, how can we possibly be using any energy to do anything? What matters, it turns out, isn’t simply energy – it’s useful energy. And energy is useful when it comes packaged in a low-entropy form. The total amount of energy in any closed system…

    Climate change explained: do green policies harm developing economies? | FT

    Thank you. Are green energy policies jeopardising the economies of developing countries? This is a hot potato. The answer at the moment is very clearly no, because developing countries in truth have implemented almost no green energy policies, partly because, at least until the Paris accord, they didn’t really have any obligations to do so. It was deliberately structured up to then as a system in which the developed countries had obligations – not that they did much – and the developing countries didn’t. Up until now, a lot of developing countries have been saying that it’s all very well for the developed countries to essentially say we need to…

    Trump Tells Earth to Go F**k Itself: The Daily Show

    I know the big news of the day is Trump pulling out of the Paris climate accord, but before getting into that, there’s one story that, as New Yorkers, we have to address. Mr. Met is out of a job at the moment. TV REPORTER: Mr. Met is fired. TV REPORTER: He’s out of there, and here’s the reason why. The video of the New York Mets mascot giving a fan the middle finger. You know, it’s kind of sad that he got fired. I mean, look at him, look at him. What other job could he possibly get? Huh? It’s not like he can go work for Uber, right?…

    Master in Green Energy Technology

    As we know, we are facing different problems, such as global warming, climate changes, depletion ozone layer, and also depletion of natural sources. We need to have some educated and skilled people to solve this problems, and to face these challenges. Through this master program, you will be trained how to solve and how to manage energy use in the world. My name is Shima Pilevar, and I work as an associate professor at Østfold University College. I’m also the program coordinator of Master in Green Energy Technology. This master program contains two main profiles; Smart energy technology and material for energy technology. The main goal for this masterprogram is…
