  1. #SpaceDatacenters proposed by #Musk and #Bezos ‘catastrophic’ for planet, experts warn

    New US petition demands review of plans from #TechCompanies amid fears of #EnvironmentalDestruction

    Excerpt: "The number of active #satellites in orbit has grown exponentially from about 1,400 in 2015 to about 15,000 currently. As many as 100,000 are expected to be in orbit within the decade, not including the #datacenter networks. As of now, the bulk of the satellites’ pollution is thought to come from #Starlink and Amazon’s '#MegaConstellations' that provide broadband internet made up of about 10,000 satellites.

    "Spacecraft can cause problems on their way up and down. Launches emit a range of emissions like #BlackCarbon, #NitrogenOxides, #CarbonMonoxide, #AluminumOxide, #ChlorineGases and, once in orbit, #mercury. When satellites are decommissioned five to 15 years later, they release metals as they vaporize. That’s injecting #pollutants into previously pristine parts of the #stratosphere, a highly sensitive system, and there’s very little understanding of the consequences."

  17. ✈️ Contrail cirrus are one of the main issues of aviation emission due to their positive radiative forcing. Researchers have found that sulfur and volatile organic compounds are the main cause of ice crystal formation – rather than soot as previously thought.

    We put together tens of studies on the mass absorption cross section (MAC) of atmospheric #BlackCarbon aerosols. Large uncertainties in MAC values are mostly due to artifacts of the measurement techniques.
