(Note to front page viewers: must open the page to see the graphic in action.) This dynamic graph (or GIF, to be technical) is one of the best graphics I’ve seen (ever.. on any topic). It so accurately explains, or showcases, global warming “skeptic” (i.e. denier) logic. Basically, it highlights how they can go on cherry picking for ages and continue saying “the world is cooling” when it’s obviously warming.
From the post it came from, “Going Down the Up Escalator,” here’s the on-point intro:
One of the most common misunderstandings amongst climate “skeptics” is the difference between short-term noise and long-term signal. In fact, “it hasn’t warmed since 1998” is ninth on the list of most-used climate myths, and “it’s cooling” is fifth.
This myth stems from a lack of understanding of exactly what global warming is. The term refers to the long-term warming of the global climate, usually measured over a timescale of about 30 years, as defined by the World Meteorological Organization.
