A shutdown would have devastating global impacts and must not be allowed to happen, researchers say Climate scientists have detected warning signs of the collapse of the Gulf Stream, one of the planet’s main potential tipping points. The research found “an almost complete loss of stability over the last century” of the currents that researchers call the Atlantic meridional overturning circulation (AMOC). The currents are already at their slowest point…
A new study tracking the planet’s vital signs has found that many of the key indicators of the global climate crisis are getting worse and either approaching or exceeding, key tipping points as the earth heats up. Overall, the study found some 16 out of 31 tracked planetary vital signs, including greenhouse gas concentrations, ocean heat content and ice mass, set worrying new records. “There is growing evidence we are…
Four days before deadly floods swept through western Germany and parts of Belgium last week, Hannah Cloke saw a forecast of extreme rain on a Europe-wide flood alert system to which she belongs. Researchers “were stupidly congratulating ourselves that we were forecasting something so early. … The assumption was that would be really helpful,” says the hydrologist and flood forecaster at the University of Reading. Instead, she was stunned to…

Her family vineyard and guesthouse, the Weingut Sonnenberg, would normally be filled with tourists descending the red wine…
Desert plants – famous for tolerance of torrid landscapes – are dying at an alarming rate due to the twin threats of even hotter weather and less rain, according to last research. After analyzing more than three decades of satellite data, University of California, Irvine, scientists found a 37% decline in native vegetation across nearly 5,000 square miles of the Southern California Sonoran Desert, from the Mexican border north across…
