    Réchauffement et chaos climatiques : face aux risques pour les profits de la classe capitaliste, la solution du « #météo_business »

    Entreprises privées de prévision météo : « Avec le #changement_climatique et les événements météo tangibles, les PDG reconnaissent qu’il peut y avoir un besoin »

    Quelle quantité de pluie et de soleil y aura-t-il pour faire pousser les récoltes ? Combien d’énergie solaire va remonter dans le réseau électrique, et quelle sera la demande d’électricité ? Un camion réfrigéré sera-t-il nécessaire pour livrer les vaccins aux pharmacies ? Faut-il mettre les parapluies en vitrine, réapprovisionner les boutiques en crème glacée et en sodas ?

    Dans la vie de tous les jours, les entreprises sont un peu comme Madame Michu : elles n’arrêtent pas de causer de la pluie et du beau temps. A plus forte raison lorsqu’elles sont exposées au changement climatique. Ce risque croissant a ouvert un boulevard aux spécialistes privés de la prévision météorologique, comme #WeatherNews, #DTN, #Accuweather. Ces entreprises qui ne sont ni des start-up ni des multinationales malgré leur forte internationalisation sont en train de diversifier leurs services de conseil, dans une multitude de métiers, et bien au-delà de la #météo.

    Deux d’entre elles se sont installées à Norman, sur le campus de l’université d’Oklahoma, un long tapis de verdure semé de bâtiments de brique rouge disparates. C’est là qu’est implanté le National Severe Storms Laboratory (NOAA), le centre météorologique public qui prévoit et surveille l’apparition des tornades sur tout le territoire américain.

    […] A l’origine, les armateurs se préoccupaient uniquement de la sécurité des bateaux. Mais ils ont désormais accès à des prévisions variées, qui ont un impact direct sur leur compte de résultat, explique Mark Glander : « C’est bien plus que de la météo. Nous pouvons prédire combien de temps va durer le voyage, combien de fuel vous allez brûler, et combien cela va coûter ».

    […] de nombreux métiers commencent juste à découvrir l’importance du conseil météo, assure-t-il : « On ne fait que gratter la surface. On peut résoudre tant de problèmes », dit-il, après avoir évoqué les voitures électriques dont la durée de batterie est parfois divisée par trois à cause du froid, ou les voitures autonomes démunies contre les routes verglacées.

    « On croit souvent qu’on ne peut rien faire en cas de mauvaise météo, ce qui n’est pas vrai, et ce qui pousse à prendre de gros risques réputationnels », insiste-t-il. Si l’organisateur d’un concert en plein air de 10.000 personnes laisse les spectateurs se garer dans la boue, l’affaire peut rapidement devenir un « désastre logistique », illustre-t-il. A l’inverse, en cas de chaleur, mieux vaut prévoir des bouteilles d’eau pour éviter les évanouissements.

    A startling new discovery could destroy all those global-warming doomsday forecasts

    Source: Investors Business Daily by staff

    “Scientists just discovered a massive, heretofore unknown, source of nitrogen. Why does this matter? Because it could dramatically change those dire global warming forecasts that everybody claims are based on ‘settled science.’ The researchers, whose findings were published in the prestigious journal Science, say they’ve determined that the idea that the only source of nitrogen for plant life came from the air is wrong. There are vast storehouses in the planet’s bedrock that plants also feed on. This is potentially huge news, since what it means is that there is a vastly larger supply of nitrogen than previously believed. University of California at Davis (...)

      Convergent evidence for widespread rock nitrogen sources in Earth’s surface environment | Science
      ▻http://science.sciencemag.org/content/360/6384/58.full

      $Freed from a rocky embrace*
      Nitrogen availability is a central controller of terrestrial plant growth and, thereby, of the carbon cycle and global climate change. It has been widely assumed that the atmosphere is the main source of terrestrial nitrogen input. Surprisingly, Houlton et al. now show that bedrock is just as large a nitrogen source across major sectors of the global terrestrial environment. They used three diverse and largely independent assessments of the nitrogen mobility and reactivity of rocks in the surface environment. These approaches yielded convergent estimates pointing to the equal importance of the atmosphere and bedrock as nitrogen sources.

      Science, this issue p. 58

      Abstract
      Nitrogen availability is a pivotal control on terrestrial carbon sequestration and global climate change. Historical and contemporary views assume that nitrogen enters Earth’s land-surface ecosystems from the atmosphere. Here we demonstrate that bedrock is a nitrogen source that rivals atmospheric nitrogen inputs across major sectors of the global terrestrial environment. Evidence drawn from the planet’s nitrogen balance, geochemical proxies, and our spatial weathering model reveal that ~19 to 31 teragrams of nitrogen are mobilized from near-surface rocks annually. About 11 to 18 teragrams of this nitrogen are chemically weathered in situ, thereby increasing the unmanaged (preindustrial) terrestrial nitrogen balance from 8 to 26%. These findings provide a global perspective to reconcile Earth’s nitrogen budget, with implications for nutrient-driven controls over the terrestrial carbon sink.

    How to start with “VANE language” API – MODIS example

    ▻http://www.digital-geography.com/start-vane-language-api-modis-example

    http://www.digital-geography.com/wp-content/uploads/2017/05/OWM-MODIS_weather.png

    The VANE geospatial platform, that’s coming out of the Beta now, is a new project we started at #Openweathermap, relying on our expertise in providing well-designed #APIs for #weather #data which is widely used by devs community. The VANE concept is to unite all operations with remote sensing data into consistent queries, allowing users to work with the data similar to the other #SQL-fashioned APIs, they are probably familiar with. This approach is different from what the typical workflow of Earth observation data usually is. Typicaly one needs to search for the certain imagery or dataset through the catalog, then place an order, then download it from FTP and process it in some desktop software he knows how to deal with, etc. That’s why the cloud-based data processing workflows are developing very fast towards providing users with most capabilities online.

    So what do we get with “VANE language” API and how it works?

    – You can SELECT by time, source, date-time period, imagery bands, tile coordinates and many other parameters, specifying the appropriate one.
    – You can APPLY online processing with multispectral 16-bit imagery, like difference indices, Change Detection, custom color processing…
    – And finally, you GET the result instantly as tiles or GeoJSON-polygon.

    Spy agencies fund climate research in hunt for weather weapon, scientist fears | Environment | The Guardian
    ▻http://www.theguardian.com/environment/2015/feb/15/spy-agencies-fund-climate-research-weather-weapon-claim

    A senior US scientist has expressed concern that the intelligence services are funding climate change research to learn if new technologies could be used as potential weapons.

    Spy agencies could be funding geo-engineering research in pursuit of weaponising the weather, scientists claims - Science - News - The Independent
    ▻http://www.independent.co.uk/news/science/spy-agencies-could-be-funding-geoengineering-research-in-pursuit-of-w

    Professor Robock’s concerns come as a major report on geo-engineering is to be published this week by the US National Academy of Sciences. Among the report’s list of sponsors is the “US intelligence community", which includes Nasa, the National Oceanic and Atmospheric Administration, and the US Department of Energy.

    The professor alleges that the #CIA told a colleague of his that it wanted to fund the report, but claimed that it did not want this fact to be too obvious – he added that the CIA is “a major funder” of the report which “makes me really worried about who is going to be in control”.

    He claimed the US government had a proven history of using the weather in a hostile way, citing the action of seeding clouds during the Vietnam War to muddy the Ho Chi Minh foot-trail and attempt to cut it off, as it was used as a supply route but the north Vietnamese.

    He claimed the CIA had also seeded clouds over Cuba “to make it rain and ruin the sugar harvest”.

    Two Palestinian babies have died due to cold #weather in the Gaza Strip, an official said Saturday, as winter storms lashed the region. A two-month-old girl from the southern Gaza town of Khan Yunis died on Friday of “a pulmonary obstruction caused by the cold,” health ministry spokesman Ashraf al-Qudra said. A one-month-old boy, also from Khan Yunis, died on Saturday, he said without giving further details. read more

    More than 4,000 people have been evacuated from flood-damaged homes in northern Gaza in what the United Nations has called “a disaster area,” officials said on Saturday. Flooding has been so severe that access to many homes is by rowing boat and water is reported to be two meters (more than six feet) high in some places. Many people have been trapped inside inundated homes by rising waters. The flooding is the result of four days of torrential rains. read (...)
