   *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?"
