    How mountaintop mining affects life and landscape in West Virginia – PBS (2017)

    Coal has been one of the work horses of power generation but its dominance is dwindling. In 2016 U.S. coal energy industry employed around 160,000 workers while solar energy production employed around 370,000. Coal has been a massive contributor to the accumulation of carbon dioxide in the atmosphere leading to mercury pollution with subsequent biomagnification throughout the food chain, ocean acidification and global warming. Some geologists propose that fossil fuel use including coal may be accepted as an indicator for […]

  • Acid Test – Natural Resources Defense Council (2009)

    Acid Test – Natural Resources Defense Council (2009)

    Since the beginning of the industrial revolution a quarter of the carbon that has been released into the atmosphere was absorbed by the oceans. As a result the acidity of the oceans has increased by %30. Increasing acidity makes it corrosive dissolving the calcium shells of marine organisms. Among them are planktons, corals and pteropods which form the base of the food web. Carbon dioxide dissolves higher quantities in cold water, therefore first biological signs of acidification is observed closer […]

  • A Tour of the Cryosphere – NASA Goddard Space Flight Center (2009)

    A Tour of the Cryosphere – NASA Goddard Space Flight Center (2009)

    The cryosphere covers parts of the Earth’s surface where water is found in the form of snow, sea ice, glaciers, permafrost, ice sheets, and icebergs. Ice and snow exist close to their melting point. Fluctuations in surface temperatures of our planet leads to frequent state changes in water from solid to liquid and back. Using satellite observations scientists monitor such changes in the global and regional climate. The Earth’s cryosphere shrink and expand on a yearly basis. The animation begins […]

  • Weekly Changes in Arctic Sea Ice Age During 1984 – 2016 – NASA/SVS (2017)

    Weekly Changes in Arctic Sea Ice Age During 1984 – 2016 – NASA/SVS (2017)

    NASA’s Scientific Visualization Studio (SVS) has produced an animation showing the sea ice dynamics in the Arctic. The diminishing ratio of multi-year sea ice is staggering. Human contribution to global warming is well documented. The response of the polar regions to heating especially in the Arctic is extremely fast. While scientists are rushing to predict future temperature and precipitation using exceedingly complex climate models, the behavior of the cryosphere is a curious one. We are already witnessing rather large glacial […]

  • Geological History of the Continents/Paleomap Project –  Christopher Scotese (2015)

    Geological History of the Continents/Paleomap Project – Christopher Scotese (2015)

    Geology and biological evolution of life are inseparable. More than half of the minerals now incorporated into the upper crust of our planet were produced by living organisms. The movement of continental plates has played a fundamental role in the recycling of mineral resources by the biosphere. Scientists now predict that tectonic activity may have been one of the prerequisites for the origin of life. The acceptance of continental drift by the scientific community and how it affected Earth’s history […]

  • Climatic Dynamics of Monsoons – NASA SVS (2016)

    Climatic Dynamics of Monsoons – NASA SVS (2016)

    The monsoon was noticed for the first time in India. It is a seasonal rain and wind pattern that occurs in many places on our planet. The quasi-regular atmospheric pattern is hugely influential in Human history. The first truly global economy was established in the Indian ocean by sea faring merchants who traveled from Africa and middle east all the way to Indonesia and Malaysia and back. Predictability of the wind patterns around the Indian Ocean was the defining factor. […]
