A global team of scientists including Dr Thomas Newsome at the University of Sydney and international colleagues has warned that “untold human suffering” is unavoidable without deep and lasting shifts in human activities that contribute to greenhouse gas emissions and other factors related to climate change.
The declaration is based on scientific analysis of more than 40 years of publicly available data covering a broad range of measures, including energy use, surface temperature, population growth, land clearing, deforestation, polar ice mass, fertility rates, gross domestic product and carbon emissions.
“Scientists have a moral obligation to warn humanity of any great threat,” said Dr Newsome from the School of Life and Environment Sciences. “From the data we have, it is clear we are facing a climate emergency.”
In a paper published today in BioScience, the authors from the University of Sydney, Oregon State University, University of Cape Town and Tufts University, along with more than 11,000 scientist signatories from 153 countries, declare a climate emergency, present data showing trends as benchmarks against which to measure progress and outline six areas of action to mitigate the worst effects of a human-induced climate change.
