    California’s methane super-emitters

Methane is a much more potent greenhouse gas than carbon dioxide, trapping much more heat. Point-source methane emitters are typically small—usually less than 10 meters in diameter—but they emit plumes of highly concentrated methane. So if we want to reduce the amount of methane we’re spouting into the air (which we obviously should, although we’re not ), they’d be great potential targets. If only we could identify them.

To map such point emissions, scientists in California flew over the state with an airborne imaging spectrometer, using it to measure methane emissions. They focused on a long list of potential sources: oil and gas production, processing, transmission, storage, and distribution equipment; refineries; dairy-manure management sites; landfills and composting facilities; wastewater-treatment plants; gas-fired power plants; and liquified and compressed natural gas facilities.

Most facilities, especially the dairies and the oil fields, were in the San Joaquin Valley. The researchers ended up measuring emissions from 564 distinct sources at 250 different facilities. These point emitters had not really been examined before, because they often only belch out their methane intermittently or in a somewhat sporadic manner. To catch them in the act, the researchers repeated the flyovers five times between August 2016 and October 2018.

    The next PlayStation will include a power-sipping 0.5W “suspend” mode

The next Sony PlayStation will have a new, more efficient "suspend" mode that will draw "around 0.5W" while allowing users to jump quickly back into a game on restart. The mode, Sony says, will save energy "equivalent to the average electricity use of 1,000 US homes" for every million PlayStation users who enable it.

A standby power drain of less than a watt would be down significantly from the 10W "rest mode" power draw we measured for the PS4 . It's also much less than the 17 or so watts we measured for the Xbox One's standby mode at launch (though that came down to about 12.9W by 2015, thanks to system updates and the elimination of the Kinect's "listening" microphone).

Sony was also quick to trumpet energy-efficiency achievements in the current PlayStation 4, including "System-on-a-Chip architecture integrating a high-performance graphics processor, die shrink, power scaling, [and] energy-saving modes such as Suspend-to-RAM." The company estimates those efforts have saved 16 million metric tons of carbon from being produced, a number that will increase to 29 million in the next 10 years (though it's unclear what baseline forms the basis for that comparison).

    Rebellyons-nous, occupation du pont Wilson à #Lyon

    Timothée Jaussoin – Monday, 16 September - 07:46 edit

Le dimanche 15 septembre 2019, sous un soleil de plomb nous avons bloqué avec succès le pont Wilson en plein centre de #Lyon.

Cet évènement coup de poing, non-violent et festif nous a permis de dénoncer la gravité de la situation face aux chamboulements écologiques et climatiques que nous vivons présentement et à venir très prochainement.

Cet évènement a été relayé dans la presse par Rue89 et a fait l'ouverture du journal du soir France3 Rhône-Alpes.

De nombreuses actions de désobéissance civiles non-violentes sont à prévoir prochainement. Plus d'informations sur le site officiel de XR France et sur le site international.

    putin puts down the heat

To his credit Putin has no qualms about yanking the chain of climate obsessed Western Politicians. During the recent G20 conference in Australia, when asked why there was a fleet of Russian Warships just outside Australian territorial waters, the Russian embassy replied the ships were there to research “climate change”.
