    How to Build a Climate Laboratory – Julia Slingo – Royal Institution (2016)

    Climate models have revolutionized our understanding of the world. Julia Slingo, the Met Office Chief Scientist and High Level Group Scientific Advisor to the European Commission, examines the processes controlling the planetary climate system. Realistic encapsulation of these processes in models increases our predictive power tremendously. Climate science works at so many different fields and scales with a common goal of converging into a common truth. Some scientists study mass balance of glaciers measuring growth and shrinkage of the cryosphere. […]

  • 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. […]

  • Updates from NASA’s Curiosity Rover [Mars Science Laboratory]

    Updates from NASA’s Curiosity Rover [Mars Science Laboratory]

    Geological evolution of the Earth and Mars have started from very similar origins but yet the two planets have followed quite different trajectories. Geology of our planet has shaped the evolution of life (and vice versa). Understanding Mars will also help understand our own planet. For this reason, Nature Documentaries will be paying attention to this ambitious Mars rover project. Jet Propulsion Laboratory has been holding regular detailed update sessions. You can follow some of these updates below starting from […]

  • Welcome to the Anthropocene – a Film About the State of the Planet – UN Rio+20 Summit (2012)

    Welcome to the Anthropocene – a Film About the State of the Planet – UN Rio+20 Summit (2012)

    Due to Human activities our planet has now reported to have entered into a “no analog state”. This means our planet has never experienced fast changing present-day conditions in its geological and evolutionary history. The closest geological event to what is happening now is known as (PETM) Paleocene-Eocene Thermal Maximum. PETM took place 56 million years ago. Changes happening now is way too fast, much faster than those in PETM. We are indeed in a no analog state in ecological […]

  • Journey Into The Sun – KQED QUEST (2010)

    Journey Into The Sun – KQED QUEST (2010)

    The Sun is the most influential celestial object for life as we know it. Understanding and predicting its behavior is essential for our existence. Plants are green because our Sun is a red star. However in the early days of life this relationship was quite different. The young Earth was spinning much faster and the days were 8 hours long. The Sun was less bright and cooler. The early photosynthesizing organisms were purple to maximize light harvesting in liquid environment. […]

  • Total Solar Eclipse in Brazil and Turkey – Sunrise Earth – David Conover (2006)

    Total Solar Eclipse in Brazil and Turkey – Sunrise Earth – David Conover (2006)

    A total solar eclipse recorded in two countries on the same day of March 29th, 2006 by the Sunrise Earth team. The Sunrise Earth series belongs to a genre known as “Experiential TV”, developed by David Conover. The genre was also precursor to the Slow TV genre famously popularized by the Norwegian director Thomas Hellum. In this poetical recording, the eclipse starts in Baia Formosa of Natal, Brazil and moves towards the east to Aspendos of Antalya, Turkey. You can […]

    PETM – Unearthing Ancient Climate Change – Science Bulletins – AMNH

    Scientists have a few hypotheses but no theory has yet emerged about a significant bio-geological event that happened fifty-five million years ago. What we know for sure was that there was a sudden, enormous influx of carbon that has dissolved in the ocean and atmosphere. As atmospheric CO2 content increased, the average global surface temperature rose 5°C to 9°C (9°F to 16°F). This global warming event is called the Paleocene-Eocene Thermal Maximum (PETM) and lasted for 170,000 years. Events triggered […]

  • What’s Really Warming Up Our Planet? NASA – SVS (2015)

    What’s Really Warming Up Our Planet? NASA – SVS (2015)

    NASA’s Scientific Visualization Studio (SVS) produced yet another visual to show how industrial and natural factors have been contributing to the global warming. These factors are wobbling of Earth’s axis, solar activity, volcanoes, land use, ozone pollution, aerosol pollution, greenhouse gases and their combined effects. The case is rather clear. Combined effects of man made factors follow the trajectory of warming closely. Since 1880 our planet warmed 1.4 degrees Fahrenheit and continues to increase. The atmospheric carbon concentration has passed […]

    The Day The Mesozoic Died HHMI – Sean B. Carroll (2012)

    This is one of the four educational video series by Sean B. Carroll produced for communicating evolution to public with the support of HHMI. Today we know the cause of the disappearance of the dinosaurs at the end of the Cretaceous period. This knowledge was produced by the meticulous coordinated work of many scientists. The Day The Mesozoic Died focuses on how scientists do the detective work using the scientific method. The discovery that an asteroid struck the Earth 66 […]

  • Perpetual Ocean from NASA

    Perpetual Ocean from NASA

    Understanding large-scale global climate and local weather patterns is important. Majority of our planet is covered by oceans therefore understanding ocean dynamics is key for making climatic forecasts. Here you can watch four interrelated animations produced by NASA’s Scientific Visualization Studio in a single video. All animations are based on simulations of high resolution satellite data on an impressively realistic General Circulation Model (GCMs) that NASA uses called ECCO2 (Estimating the Circulation and Climate of the Ocean Phase II). These […]

    Rosetta Mission to Comet 67/P – Exploratorium (2015)

    Paul Doherty of the Exploratorium explains phases of the European Space Agency’s Rosetta Mission to the comet 67P/Churyumov–Gerasimenko in exquisite detail. Comets are extremely interesting celestial objects. They may have even played role in jump starting life on our planet. When and how chemistry became biology is a burning question for everyone. There has been a period way in the past during the early times of the Earth when meteorites and comets bombarded its surface. This period is known as […]

    Global Aerosol and Dust Dynamics – NASA SVS

    The main video featured above consists of three interrelated parts produced separately by NASA’s Scientific Visualization Studio (SVS) which has been producing highly engaging visualizations based on actual and simulated data about global processes running our planet. First narrated visualization shows transport of dust from the Africa to South America between 2007-2013 where the Sahara desert is the source and the tropical Amazon basin is the sink. The scale of interaction between the driest and the wettest places on earth […]

  • Aerosols and Cloud Formation – NASA/SVS

    Aerosols and Cloud Formation – NASA/SVS

    When and where clouds form are important for climate science. Long-term observations have shown that at any given time less than 10 percent of the Earth’s skies are clear with no clouds. We most certainly want to know what is going on in the major 90 percent fraction covered with clouds of some type. Some clouds reflect the sun’s radiation while others trap outgoing heat that would otherwise be emitted to space. Tiny solid and liquid particles suspended in the […]

  • What Caused the Cambrian Explosion? – The Economist (2015)

    What Caused the Cambrian Explosion? – The Economist (2015)

    It was a big curiosity for early geologists. For roughly 90% of the Earth’s history it appeared as if there was no life. After this long static period at about 542 million years from present life forms as we know of today began to appear bursting over a relatively short time (over 20 million years). Colloquially, this time period is called “Cambrian Explosion”. All of these life forms were of course aquatic: Annelids, arthropods, brachiopods, echinoderms, molluscs and ancestors of […]
