The Cloud Mystery
''The Cloud Mystery'' is a documentary by Danish director Lars Oxfeldt Mortensen. It explores the theory by Danish scientist Henrik Svensmark on how galactic cosmic rays and solar activity affects cloud cover, and how this influences the earth's climate. Also known as ''Klimamysteriet'' in Danish. This documentary presents the work done to develop the theory that cloud cover change is caused by variations in cosmic rays as the major originator of global climate variation. It also mentions that these scientists do not subscribe to the scientific consensus on climate change, which says that human influence and the effect of greenhouse gases are significant drivers of climate. However, the focus is on the work they have done and not on the consensus on anthropogenic global warming. Release ''The Cloud Mystery'' aired on TV2 (Denmark) in early 2008. It was also shown on Norway's NRK and on TV4 Fakta, (which can be viewed in Sweden and Finland.) and on Arte (April 2. 2010, "Das Gehe ...

He held postdoctoral positions in physics at three other organizations: University of California, Berkeley, Nordic Institute for Theoretical Physics, and the Niels Bohr Institute. In 1997, Svensmark and Eigil Friis-Christensen popularised a theory that linked galactic cosmic rays ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Documentary Film
A documentary film or documentary is a non-fictional film, motion-picture intended to "document reality, primarily for the purposes of instruction, education or maintaining a Recorded history, historical record". Bill Nichols (film critic), Bill Nichols has characterized the documentary in terms of "a filmmaking practice, a cinematic tradition, and mode of audience reception [that remains] a practice without clear boundaries". Early documentary films, originally called "actuality films", lasted one minute or less. Over time, documentaries have evolved to become longer in length, and to include more categories. Some examples are Educational film, educational, observational and docufiction. Documentaries are very Informational listening, informative, and are often used within schools as a resource to teach various principles. Documentary filmmakers have a responsibility to be truthful to their vision of the world without intentionally misrepresenting a topic. Social media platfor ...

Carbon Dioxide
Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

Global Warming
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

The Great Global Warming Swindle
''The Great Global Warming Swindle'' is a 2007 British polemical documentary film directed by Martin Durkin. The film denies the scientific consensus about the reality and causes of climate change, justifying this by suggesting that climatology is influenced by funding and political factors. The program was formally criticised by Ofcom, the UK broadcasting regulatory agency, which ruled the film failed to uphold due impartiality and upheld complaints of misrepresentation made by David King, who appeared in the film. The film presents scientists, economists, politicians, writers, and others who dispute the scientific consensus regarding anthropogenic global warming. The programme's publicity materials claim that man-made global warming is "a lie" and "the biggest scam of modern times." Its original working title was "Apocalypse my arse", but the title ''The Great Global Warming Swindle'' was later adopted as an allusion to the 1980 mockumentary'' The Great Rock 'n' Roll Swind ...

The Chilling Stars
''The Chilling Stars'' is a non-fiction book about the possible causes and effects of global climate change by Henrik Svensmark and Nigel Calder. The paperback version was published by Totem Books on March 19, 2003. An updated version titled ''The Chilling Stars: A New Theory of Climate Change'' was published in 2007. Svensmark is otherwise known as a Danish physicist and professor, while Calder had worked as a science journalist. The authors argue that cloud cover changes caused by variations in cosmic rays are a major contributor to global temperature increases, and they state that human influences have been exaggerated. Contents and background The authors describe a cross-disciplinary theory that takes in elements of cosmology, particle physics, paleo-climatology, and meteorology. They label their concept 'cosmoclimatology', and they attempt to look back through prior climate trends such as the Medieval Warm Period and the Little Ice Age. They detail what they view as a c ...

Cloud Condensation Nuclei
Cloud condensation nuclei (CCNs), also known as cloud seeds, are small particles typically 0.2 µm, or one hundredth the size of a cloud droplet. CCNs are a unique subset of aerosols in the atmosphere on which water vapour condenses. This can affect the radiative properties of clouds and the overall atmosphere. Water requires a non-gaseous surface to make the transition from a vapour to a liquid; this process is called condensation. In the atmosphere of Earth, this surface presents itself as tiny solid or liquid particles called CCNs. When no CCNs are present, water vapour can be supercooled at about for 5–6 hours before droplets spontaneously form. This is the basis of the cloud chamber for detecting subatomic particles. The concept of CCN is used in cloud seeding, which tries to encourage rainfall by seeding the air with condensation nuclei. It has further been suggested that creating such nuclei could be used for marine cloud brightening, a climate engineering techni ...

Barred Spiral Galaxy
A barred spiral galaxy is a spiral galaxy with a central bar-shaped structure composed of stars. Bars are found in about two thirds of all spiral galaxies, and generally affect both the motions of stars and interstellar gas within spiral galaxies and can affect spiral arms as well. The Milky Way Galaxy, where the Solar System is located, is classified as a barred spiral galaxy. Edwin Hubble classified spiral galaxies of this type as "SB" (spiral, barred) in his Hubble sequence and arranged them into sub-categories based on how open the arms of the spiral are. SBa types feature tightly bound arms, while SBc types are at the other extreme and have loosely bound arms. SBb-type galaxies lie in between the two. SB0 is a barred lenticular galaxy. A new type, SBm, was subsequently created to describe somewhat irregular barred spirals, such as the Magellanic Clouds, which were once classified as irregular galaxies, but have since been found to contain barred spiral structures.

Milky Way
The Milky Way is the galaxy that includes our Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. The term ''Milky Way'' is a translation of the Latin ', from the Greek ('), meaning "milky circle". From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s, most astronomers thought that the Milky Way contained all the stars in the Universe. Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis, observations by Edwin Hubble showed that the Milky Way is just one of many galaxies. The Milky Way is a barred spiral galaxy with an estimated D25 isophotal diameter of , but only about 1,000 light years thick at the spiral arms (more at the bulg ...

Cosmic Ray
Cosmic rays are high-energy particles or clusters of particles (primarily represented by protons or atomic nuclei) that move through space at nearly the speed of light. They originate from the Sun, from outside of the Solar System in our own galaxy, and from distant galaxies. Upon impact with Earth's atmosphere, cosmic rays produce showers of secondary particles, some of which reach the surface, although the bulk is deflected off into space by the magnetosphere or the heliosphere. Cosmic rays were discovered by Victor Hess in 1912 in balloon experiments, for which he was awarded the 1936 Nobel Prize in Physics. Direct measurement of cosmic rays, especially at lower energies, has been possible since the launch of the first satellites in the late 1950s. Particle detectors similar to those used in nuclear and high-energy physics are used on satellites and space probes for research into cosmic rays. Data from the Fermi Space Telescope (2013) have been interpreted as evidenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proceedings Of The Royal Society A
''Proceedings of the Royal Society'' is the main research journal of the Royal Society. The journal began in 1831 and was split into two series in 1905: * Series A: for papers in physical sciences and mathematics. * Series B: for papers in life sciences. Many landmark scientific discoveries are published in the Proceedings, making it one of the most historically significant science journals.
