Here’s my fifth Cranky Uncle video, debunking the myth that we’re heading into an ice age. This animated video is adapted from cartoons in the Cranky Uncle vs. Climate Change book.
Here is a graph of solar activity (an 11-year average to be precise, to smooth out the year-to-year variability). It shows that since the latter half of the 20th Century, the sun has been cooling.
However, even if solar activity fell to the low levels of the 1600s when part of the world went through a “Little Ice Age”, it would have minimal effect on future warming due to greenhouse gas emissions. This is based on research by Georg Feulner and Stefan Rahmstorf (disclaimer: the original research does not include a caricature of Jon Snow).
If you want to delve into this myth in greater detail, we debunk the myth “we’re heading into an ice age” at Skeptical Science. We also debunk the myth in our MOOC Denial101x: Making Sense of Climate Science Denial:
