How Fast Will Sea Levels Rise? No one Really Knows

Messing up our climate with excessive CO2 emissions is taking huge risks.  With the concentration of CO2 in the atmosphere rising faster every year, and massive releases of stronger greenhouse gases like methane (natural gas), it is likely that sea levels will continue to rise worldwide.  What people don’t remember is that small changes in sea level have happened all along, and that it wasn’t that long ago when, because we were still emerging from the last ice age, sea levels were several feet (or tens of feet) lower.  Now humanity has built so heavily in areas near sea level that almost any rise is reflected in an increased frequency of damaging floods.   In some areas the flooding already happens from a high tide, and no storm or other weather event is needed.

There is a lot more ice (and potential sea level rise) than most people realize.  Another thing people don’t realize is that there is enough ice on land in just Greenland and Antarctica to increase sea levels by 200 FEET!  If some portion of this increase happens quickly, in less than a month, for instance, humanity will be completely surprised and “caught with our pants down” as famine and pandemic result.  So much of our food reaches us via container ships that, when the container ports are shut down by a sea level increase of a foot or two, shiploads of food will spoil at sea, grocery store shelves will get sparse, and there is a danger of people panicking and making runs on the grocery stores and banks.

I certainly hope humanity comes to its senses soon.   Thanks for reading — Tim


Empty Subdivisions and Crumbling Infrastructure Could Follow the Population Explosion

With  the population over 7 billion people now, heading for 10 billion by 2050 or so, the earth’s resources will be insufficient, sooner or later, and there will be a period of problems that will result in population collapse.  After that decade (or three) of ever larger natural disasters, epidemics and wars we will be left with vast wildernesses of empty, decaying buildings.  The infrastructure will be, at best, worse than it is now, and nonexistent in some places.  The sprawling subdivisions of North America will be sparsely populated and most houses and buildings will be crumbling with nobody to keep them up, and no money or materials for the task, either.  Freeways will be useful for all kinds of traffic with very few or no cars left.  Fossil fuels will be scarce and too expensive for most people, and walking, cycling, and a revival of horse transportation will become the norm.  When the freeway overpasses crumble and fall people will just use the on and off ramps to go around them.

It is hard, from here, to imagine how the aftermath of the population explosion will play out, but times will certainly be hard.  And still there is no meaningful or constructive public discussion of how we can reduce the birthrate, and news media continue to trumpet big business’s line that growth is essential and that population decline is a thing to be avoided.  That is frightening.

Thanks for reading, and please help people understand how much more important overpopulation is than any of the problems we see daily, almost all of which result from it.  – Tim

Agricultural Practices Can Mitigate Global Warming

This article from the Weather Underground folks pulls together several study results to show how farmers around the world are finding new methods that reduce the negative effects of climate change and provide sustainable, productive agriculture.  We need a LOT more of this kind of thinking, and hopefully it will help buy us time until we can see our way to controlling the population explosion.  We will never be safe and our civilization will never be sustainable in the long run without that.

Plans Being Made to Feed 9B People in 35 Years – What Will They Do for 10B? 11B?

This article from Wired magazine shows the weakness of American popular culture.  It is good that the authors see potential problems from the population explosion, and try to come up with a way to feed the 9 billion humans expected to live by 2050, but this is a very shallow consideration.  Certainly much thought and work should be applied to this issue, but do the authors think time and the population explosion will stop there?  What do they expect to do when the population – enabled to have even more children by the plentiful food supply – continues to explode and reaches 10 billion, 11 billion, and then 12 billion?

Food Supply Risk is Increased by Decline in Home Canning and Storage

As recently as 50 years ago it was common for American families to have gardens and can or freeze what they produced.  Many people also waited for seasonal produce sales to stock up, canning or freezing the surplus food for consumption over the following year.  In addition, many people had root cellars where they could store apples, potatoes, onions, and many other food items for months at a time including over the winter.  Interruptions in the shipments of food into an area were troublesome, but not a serious problem because most people had stores of food they could subsist on for weeks or even months if necessary.  Times have changed significantly, however, and the majority of people today not only do not can or preserve food, but don’t even know how to do this.  The food in most homes would last for days or weeks at most, not weeks or months as in the past, suggesting the average person’s ability to survive in a food shortage is greatly reduced.  Why has this happened?

Can We Invent Our Way Out of the Population Explosion? Not the Way You’re Thinking.

We invented our way into this situation. Many of our past inventions made life easier, food more plentiful, etc., and enabled population growth. When anything threatened to kill us off, we fought it with creativity and developed technologies to deal with it.  Except for those inventions specifically aimed at killing people or managing our birthrates (the Chinese “One Child Law“, for example), our inventions have permitted us to thrive and propagate more and more effectively, and to increase our numbers at faster and faster rates.  The problem we perceive now is that sooner or later the needs of our unchecked population will exceed available resources.  This would seem a normal pattern for any life form, but there are plenty of examples where animal birthrates slowed inexplicably in the face of food shortages.  That makes it seem that humans have lost the instinct for avoiding population-driven catastrophes (if we ever had it), which leaves our fate up to us.  It also suggests the population challenge will require types of creativity we haven’t used before, or often.  So just  how smart are we?
