Battered by extreme weather, Americans are more worried about climate change | Dana Nuccitelli

After months of intense hurricanes, heat waves, and droughts, a survey finds a record number of Americans worried about climate change

The latest climate change survey from Yale and George Mason Universities is out, and it shows that Americans are still poorly-informed about the causes of global warming. Only 54% understand that it's mostly human-caused, while 33% incorrectly believe global warming is due mainly to natural factors.

In fact, a new study published in Nature Scientific Reports developed a real-time global warming index. It shows that humans are responsible for 1C global surface warming over the past 150 years - approximately 100% of the warming we've observed. Lead author Karsten Haustein explained their new index and study in a blog post.
