The ISCFC is all about reducing our individual and collective contributions to climate change.
But is climate change really happening? Is it mostly caused by human activity, including our production of carbon dioxide and other greenhouse gases?
In the United States and elsewhere, there are people who are not convinced by the science. But the great thing about science is that we use evidence to evaluate scientific questions. So what is the evidence related to climate change?
Are you or are you not convinced by the majority of climate scientists who say that climate change is real and largely human caused? Why are you convinced/not convinced? What evidence might change your mind one way or the other?
Is Climate Change Real & Human-Caused? >
Climate Change does Exist and it is a Threat
For the past 40 years, climate scientists have given the same unsatisfactory answer: if humans double atmospheric carbon dioxide (CO2) from preindustrial levels, the earth would warm by 1.5°C to 4.5°C, a temperature range that includes anything from a minor increase to a catastrophic one. According to James Hansen, the legendary retired NASA climate scientist who helped create the first sensitivity range in 1979, the new research is the payoff of decades of advances in climate science. Climate change is real, climate change is out there, and we can’t keep running from it.
