The work of atmospheric and climate scientists is what first alerted us to the threat of global warming. As the world attempts to address the climate crisis, scientists have been instrumental in making reliable predictions about what will actually be required to save the world from catastrophic global warming. NASA scientists James Hansen, for instance, has warned that atmospheric carbon dioxide levels must be reduced to 350 parts per million or below if the worst effects of global warming are to be avoided. Scientists like Hansen give us reliable, peer-reviewed information that can be distinguished from the hype and speculation that’s commonly thrown around by non-scientist climate deniers who seek to convince the public that global warming isn’t real. By sticking with information that originates from credible scientists whose work appears regularly in peer-reviewed journals, we can determine what really needs to be done to address the magnitude of the climate crisis.
