Playing semantics, misleading Breitbart article downplays US contribution to climate change

“This whole post is based on semantics and basically one big strawman fallacy. The author is deliberately confusing air pollution from suspended particulate matter (as discussed in the WHO report) with pollution from carbon dioxide emissions (as discussed in the Reuters link and the Paris Agreement). Even though CO2 does not impact our health through “disease-causing pollutants that get into people’s lungs”, it does change our environment and the Earth’s climate, and in that sense does classify as a pollutant.”

Analysis of "Scientists say human greenhouse gas emissions have canceled the next ice age"

“The article presents an accurate account of recently published research which suggests that human-induced global warming will delay the onset of the next ice age by 50,000 years. The research supports the findings of several studies published over the past 15 years, and is consistent with the scientific consensus that human activity is changing the climate with very long-term consequences.”
