Jem Bendell is a sociologist, not a climate scientist. He's also a doomsday alarmist. In scientific circles, there are a plethora of criticisms of his writings that range from poor and incorrect interpretation of current data, citing other scientists whose credentials and claims have been called to task and pulling attention and resources away from where it largely needs to go, which is toward addressing and educating climate change deniers. His paper was denied peer review, it appears for reasons considerably more involved than "the the study they thought you should not read" rationale he leads with on his site. And as has been pointed out by another redditor, the wording he uses to rally his readers is the type of stuff put forth by cult leaders.
If you want to learn about climate change...
- Don't read the news articles, read the research that's typically linked to in those pieces.
- Determine if the research comes from a credible source (i.e., peer reviewed).
- Either learn to interpret data, or find someone who knows how.
- If you really want to get into it (like, up to your armpits deep), there's a free, 53 hour Coursera course on the science and modeling of climate change.
There are so many emotion-leading articles out there (typically accompanied by an image of the earth aflame, coastal cities wracked by 100' waves or some other ghastly concoction) proclaiming that humanity and the planet will be destroyed in the next thirty years, but none of that is backed by current data. Granted, things are headed in a direction where many people are likely going to suffer, but that portends neither the end of civilisation nor the planet. And a lot is being done (research and implementation) to mitigate the effects of global warming, more so than most people realise.
If you want to do something about it, deal with the present. Start by voting out opportunistic, destructive cretins like Doug Fraud and his sycophantic posse, and demanding those who hope to replace him make climate change a priority issue.
