    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…

    Studying Ice Cores to Understand the Earth’s Climate

    One of the best ways to understand the Earth’s climate system as a whole is to look into the Earth’s past and to look at different time periods in the Earth’s climate history when greenhouse gases were at different levels. How much of the difference is really explained by the greenhouse gases themselves? How much is explained by other factors? Ice cores are among the best records for answering those questions. We collect ice cores both from Greenland and Antarctica. These are the two biggest ice sheets in the world, and the two ice sheets that contain really very, very old ice. If we drill down to the base of…

    How can we best protect our forests? PEFC certification!

    What can we do to protect our forests? Here at PEFC we believe the solution is to manage forests responsibly, so we can all enjoy the many environmental, social and economic benefits they provide. Vital to this is certification, which promotes sustainability. PEFC is the world’s leading forest certification system. Upholding the very highest standards, it is a global alliance of people who care passionately about our forests. We set standards for sustainable forest management. By doing so we help safeguard biodiversity and support forest owners and communities. This enables companies to source responsibly and allows consumers to buy certified products that they know will come from well-managed forests that…

    Sustainable Self

    [MUSIC PLAYING] SPEAKER 1: So to introduce our presenter tonight, we have Ben Woodman. He is from the state of Maine. He has always had a passion for the environment because he grew up hunting, fishing, hiking, and traveling. He is currently studying environmental science and hopes to work in sustainability and or education in the future. He is the chair of Environment Sustainability Alliance here at the WSU Pullman. So just to start us off and I’ll hand it over to Ben. BEN WOODMAN: Hey, guys. So this is Sustainable Self. Thanks for joining. Let’s go ahead and jump right into it. So as she was saying, I’m a…

    Is it Wrong to Fly? – Glad You Asked S1 (E6)

    This is me in China in 1996, on a trip to see where my family came from.That trip was the first time that I rode in an airplane,and the first time that I got stuck in an airport.We’ve been waiting here for 9 hours now! Air travel is one of the great privileges of living in this century. And the number of air passengers is expected to double in the next 20 years. There’s just one problem. Aviation runs on oil, which contributes to global climate change.And there’s not a good alternative yet.So individual consumers were left wonderingabout their own responsibility.These blankets represent arctic sea ice. Alex: How many polar…

    Greenhouse Effect – GCSE science, Physics (9-1)

    – Hello, this video is about the greenhouse effect, the physical process that drives global warming and climate change. So, first of all, most of our energy comes from the sun, and the sun is a giant nuclear reactor in space. The reactions going on in the sun emit electromagnetic radiation. Now, we think of the sun as producing light and warmth perhaps, but actually it’s producing the entire range of electromagnetic spectrum all the way from radio waves at the low end to gamma rays and x-rays at the upper end of energy. Now, all that light and that radiation comes through space and by and large gets through…

    Ecology and Environment: Intro

    Homo sapiens rise. While homo habilis, homo neanderthalensis and homo erectus die out, leaving us the sole surviving human species. Our capacity for abstract thought, the ability to plan ahead and the ability to record information were necessary to our survival, but also allowed us to mould the world to our will and benefit. As homo sapiens spread many species such as the mammoths and giant ground sloths were hunted to extinction. Humans gradually abandoned the hunter-gatherer life, settling in agricultural communities. This change allowed much larger groups of humans to coexist, and so our settlements grew. Land was cleared for growing crops and animal husbandry and yet more species…

    Tree Stories: How Tree Rings Reveal Extreme Weather Cycles

    When you look at a forest in Utah, whether from an airplane or hiking around, you might not realize that there’s a library of information in those trees. Each tree is recording information about the environment that it’s growing in. The main focus of my work right now is to try to reconstruct stream flow from tree rings. The process is dendrochronology, so “dendro” for tree and “chronology” for time. We primarily take very small core samples about the diameter of a pencil with a handrill and then we take it back to the lab. By cross stating the rings in this dead tree with living trees, we’ll be able…
