What if Climate Change Was a Hoax?
Description
14.8% of Americans do not believe in climate change. Recently, a study mapping a 485-million-year history of Earth’s temperature and CO2 levels has been misinterpreted by some who downplay urgent climate concerns. Their argument suggests that, since the Earth has experienced much higher temperatures and CO2 concentrations in the past, the current rise of a few degrees won’t significantly affect us – and that climate concerns are being over exaggerated
What if climate change was, in fact, a “hoax”? What if all of the climate science developed in recent decades was a fraud? Could we then just generally exhale and continue humanity’s current economic trajectory unimpeded?
Exploring these questions in today’s Frankly, Nate emphasizes the limited, ‘narrow boundary’ perspective of downplaying the urgency of climate change. A more nuanced understanding of ecology reveals that the long-term stability of our planet depends on numerous environmental tipping points, with climate change being just one of them. Even if climate change was a “hoax”, we are still causing accelerating harm to the life support systems of Earth , pushing the biosphere beyond its limits in a way which will profoundly impact our future, even our near term future.

In French, we have a motto that says that a simple drawing is often better than a long explanation. Jean-Marc Jancovici Carbone 4 President
That’s very understandable because with left atmosphere thinking, one of the problems is that you see everything as a series of problems that must have solutions. Iain McGilchrist Neuroscientist and Philosopher
We can’t have hundreds and hundreds of real relationships that are healthy because that requires time and effort and full attention and awareness of being in real relationship and conversation with the other human. Nate Hagens Director of ISEOF
This is the crux of the whole problem. Individual parts of nature are more valuable than the biocomplexity of nature. Thomas Crowther Founder Restor
