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
Climate change is real and human caused. This is because we are increasing the greenhouse effect through emissions. The greenhouse effect is created by greenhouse gases that absorb infrared radiation and heat up Earth's atmosphere. This is necessary to human survival because without it the earth would have a temperature of O°F. Through human emissions, the number of greenhouse gases has increased in our atmosphere. According to a NASA article (https://climate.nasa.gov/causes/), human industrial activities have raised the CO2 levels in our atmosphere from 280 ppm to 400 ppm in the past 150 years. The article further goes on to discuss the Intergovernmental Panel on Climate Change's fifth assessment in which they determined that there is a greater than 95% change that human industrial activities have increased the global climate in the past 50 years.
