Sea Level Rise

Sea levels are rising, and the rate is accelerating.  This is a problem because so much of civilization clusters around seashores.  Food security is also threatened due to loss of land, storms, and depleted fisheries.  :/

Here's how North America will likely look after severe ocean rise.  Worried about the Amazon rainforest?  You won't save it from this.  And don't forget Europe.

You can see why the Maldives is concerned.  Their highest land is only 7'7" above sea level, and the average is 4'11.  It'll take a lot less than global devastation to sink them, and they can already see the brutal treatment of other refugees.  What's going to happen to all the island nations as the world's waters rise up?  Nothing good.

Air Pollution Raises Violence

A study has shown that air pollution doesn't just cause health problems, it raises violence.  This one uses several different nationwide databases so it has a very broad base of information.  The scientists did not speculate on why particulates might make people more violent, just noted a correlation.

I can see several possibilities:

* Air pollution makes it harder to breathe, which makes it harder to think clearly and solve problems.

* Poor air quality would likely make the hindbrain anxious about survival, which would make it more reactive to other threats, and it can outright hijack the thinking brain -- which is possibly impaired by poor air quality and thus less able to resist.

* The change in air composition might directly alter biochemistry, such as making more stress chemicals or undermining the production of brain chemicals needed for logic and equanimity.

* A subset of particulate pollution comes from wildfire smoke.  In this instance, people already facing an existential threat from fire might might be primed for survival response rather than rational response to further threats.

* My friends in Alaska tell me that they just get used to smelling smoke all the time in fire season, and stop responding to it.  If habituation to danger signals is wider, however, people might be failing to react to threats at a distance or low levels, and wind up stuck with violence as their last option when they suddenly become aware of a serious threat at short range.

It would be interesting to explore the exact mechanism, but I doubt that would help solve the problem.  Trying to find ways of providing cleaner air would be good, but we already knew that and haven't exactly done a stellar job of pursuing it. 

Journaling Aids Mental Health

 ... and improves practical outcomes.

Blogging is a type of journaling, so if you're reading this, you're probably on the right track.  :D  If you get stuck for ideas, consider blog prompt lists or journal prompt lists.

I never realize how much I've accomplished until I pile it together trying to catch someone up on what I've been doing.  So that's one way blogging is useful to me.  I can use posts to track things over time, like my goals for the year.  I also have regular posts, like the Monday Updates, and various lists to encourage discussion, like the self-awareness questions.
