    Do farmers get a fair share for their work? Many small farms go bankrupt & one-third of U.S. net farm income in 2019 came from government aid and taxpayer-subsidized commodity insurance payments. “U.S. farm bankruptcies hit an eight-year high” | Reuters

    Turkish photographer Uğur Gallenkuş portrays two different worlds within a single image. Combining pics one of the Western world and the other of the Rest, he highlights how , despite living on the same planet , these places couldn’t be more different. Stunningly Brillian

    China is in a state of shock & panic facing the Coronavirus. People are told to stay home & not go to work. Other countries extract citizens from Wuhan. This photo shows an unreal scene of a pilot in full body protective wear. Our thoughts are with the people of Wuhan & China.

    Interested how NZ dealt with GHGs? They treat fossil fuel emissions (i.e. CO2) separately from biogenic sources & sinks (methane). Goal: zero CO2 emissions and reductions of methane combined with policies to achieve water, soil and biodiversity objectives.

    Thread by : Thread: Why are most carbon footprint estimates for livestock products so massive? In short: because they are based on a methane calculation. EAT Lancet, Starbucks, Impossible Burger etc are drastically overestimating GHG from livest…

    “Even more strikingly, if an individual [cattle or sheep] herd’s methane emissions are falling by one third of one percent per year (that’s 7/2100, so the two terms cancel out) …then that herd is no longer adding to global warming.”

    “That this formula is vastly more accurate than the traditional accounting rule is indisputable.” /7

    If there is no “rate of change” (i.e. the quantity of emissions by weight is constant over time) then there is a one-off impact of only 7 times the equivalent weight of CO2 (count only once – there is no accumulation as is the case for CO2 and other long-lived gases). /6

    To find the carbon dioxide emissions that would actually have a similar impact on global temperature as methane, you need to multiply those methane emissions by 7 (not 28), and add the rate of change of methane emissions (measured in tons of methane/year), multiplied by 2100. /5

    Climate policy has traditionally treated every tonne of methane as supposedly “equivalent” to 28 tonnes of carbon dioxide… It isn’t. /4

    Traditional greenhouse gas accounting ignores the impact of changing methane emission rates while grossly exaggerating the impact of steady methane emissions (like from constant cattle herds in most developed countries). /3

    Traditionally, the IPCC’s AR5 estimated that the global warming caused by 1 ton of livestock methane would be 28 times that of a ton of carbon dioxide. New research destroys that estimate. /2
