    *Climate tipping points could topple like dominoes, warn scientists

    Damian Carrington, The Guardian via Carbon Brief

    The Guardian covers new research published in the journal Earth System
    Dynamics which says that "ice sheets and ocean currents at risk of
    climate tipping points can destabilise each other as the world heats
    up, leading to a domino effect with severe consequences for
    humanity". The newspaper adds: "The new research examined the
    interactions between ice sheets in West Antarctica, Greenland, the
    warm Atlantic Gulf Stream and the Amazon rainforest. The scientists
    carried out 3m computer simulations and found domino effects in a
    third of them, even when temperature rises were below 2C, the upper
    limit of the Paris agreement. The study showed that the interactions
    between these climate systems can lower the critical temperature
    thresholds at which each tipping point is passed. It found that ice
    sheets are potential starting points for tipping cascades, with the
    Atlantic currents acting as a transmitter and eventually affecting the
    Amazon." The Guardian quotes one of the authors, Prof Ricarda
    Winkelmann at the Potsdam Institute for Climate Impact Research (PIK)
    in Germany: "We provide a risk analysis, not a prediction, but our
    findings still raise concern#[Our findings] might mean we have less
    time to reduce greenhouse gas emissions and still prevent tipping
    processes." Forbes also quotes Winkelmann: "While these mechanisms are well-known, the dynamics brought about by the interactions of these
    tipping elements were not. In our study, using a novel network
    approach, we provide a risk analysis of potential climate domino
    effects, where the tipping of one element triggers further tipping processes."

    In other news about new scientific findings, the Guardian carries a
    separate report about research published in the Cryosphere, which
    shows that "sea ice across much of the Arctic is thinning twice as
    fast as previously thought". The newspaper continues: "The new
    research used novel computer models to produce detailed snow cover
    estimates from 2002 to 2018. The models tracked temperature, snowfall
    and ice floe movement to assess the accumulation of snow. Using this
    data to calculate sea ice thickness showed it is thinning twice as
    fast as previously estimated in the seas around the central Arctic,
    which make up the bulk of the polar region." And Carbon Brief reports
    on new findings in Nature Climate Change which show that clouds could
    have a greater cooling effect on the planet than climate models
    currently suggest.

    Meanwhile, the Financial Times carries a comment piece by the
    University of Bristol's Prof Jemma Wadham, author of "Ice Rivers", on
    the "secret life of glaciers": "Over my 25-year career as a
    glaciologist, their majesty has dwindled as our climate has
    warmed#what we are seeing now is unprecedented in human history - and
    it's happening with nearly 8bn people on the planet, many of whom have
    come to rely on glaciers for fresh and clean water, fisheries, stable
    seas and a habitable climate#Recent records of global glacier change
    signal that we are sleepwalking towards a humanitarian crisis. The
    question is - will we choose to wake up?"

    Greater Melbourne residents who lost jobs to COVID lockdown eligible for new payment

    People who lost their jobs amid Victoria's lockdown may be eligible for a
    $500 "temporary COVID disaster payment" on a week-by-week basis, Prime
    Minister Scott Morrison says.
    [In a 270 deg turn from yest, the PM told reporters at a press conf
    the Commonwealth would be with Victorians "all the way". Yesterday the
    fed govt was saying there would be no support for households or
    businesses because the lockdown was called by the state govt. Perhaps
    someone pointed out the prev 17 wk lockdown was also called by the
    state govt and saw a doubling of unemployment benefits while people
    were unable to work as well as business subsidies intended to keep
    jobs open although some large corporations funneled that money to
    executive bonuses and stock dividends. Today the PM says the workload
    must be split. Either the Commonwealth will support business or
    households but not both; the Victorian govt must pick up the other one].
