“Scientists have a moral obligation to clearly warn humanity about any kind of catastrophic threat and to ‘tell it like it is’. On the basis of this obligation and the graphical indicators presented below, we declare, with more than 11,000 scientists signatories from around the world, clearly and unequivocally that planet Earth is facing a climate emergency”. These are the first words of the recently published article in the journal BioScience by the experts William J. Ripple Christopher Wolf (Oregon State University, United States), Thomas M Newsome (The University of Sydney, Australia), Phoebe Barnard (University of Cape Town, South Africa) and William R Moomaw (Tufts University, United States).

The new study –the scientific community claim facing the seriousness of climate emergency- reviews the published information over the last forty years regarding several processes such as the change in temperatures worldwide, the loss of ice mass in polar latitudes, growth of population, and more.

“We believe perspectives will be more important if decision-makers and the humanity promptly respond to this warning and declaration of climate emergence and act to sustain life on planet Earth, our only home”, note the authors of the new study, signed by a collective of more than 11,000 scientists from 153 countries. Among these scientists are members of the teaching and research collective of the Faculty of Biology, the Faculty of Psychology, the Faculty of Geography and History, the Biodiversity Research Institute (IRBio) and the Water Research Institute (IdRA) of the University of Barcelona.
