Current Affairs ... Technology ... Weather ...

Eight years ago, I posted some words here about whether climate change was as serious as it was being made out to be, and whether the evidence that global warming was being caused primarily by man-made CO2 and other greenhouse gasses was as solid as climate advocates had asserted. Today, given the evolving weather trends over the past decade or so, I tend to be more sympathetic to the view that climate change is real, and I generally agree that the trend is towards higher temperatures
(both air temps and sea temps) and more instability in established weather patterns.

Personally, I don’t think that emission reduction or green energy strategies are going to do much to stem the change, at least not in the next few years or even decades. In the longer term, technology will make our industrial and transport infrastructure more efficient and less dependent upon carbon-based fuels. “Renewables” (aka “green energy” sources such as wind and solar generators) along with nuclear power now meet about 21% of global energy demand. This will get close to 25% by 2020.

Renewables and nuclear might hit 50-50 parity with carbon-based fossil fuels by around 2070, according to some optimistic projections; these scenarios assume that carbon-based fuel use starts declining by 2020. However, a 2016 US Energy Information Agency projection (made during the Obama Administration) indicates that carbon fuel usage will continue to grow thru 2040. In the EIA scenario, renewables and nuclear account for  »  continue reading …

Philosophy ... Science ... Society ...

HERE IS A MAKE-BELIEVE STORY THAT I MADE UP TO HELP A NON-MATHEMATICALLY INCLINED FRIEND OF MINE TO GRASP WHAT HEISENBERG‘s UNCERTAINTY MEANS IN THE QUANTUM WORLD — SORT-OF, ANYWAY . . .

Imagine meeting a person from a different, far away place – and in that different, far away place, people get first names and last names, just like us

BUT – each person from this far away place gets a set of multiple first names, and multiple last names; E.g., the person can be [George, Martin, Louis, Roger] + [Smith, Edwards, Ortiz, Russo]. Also, every second or so, the combination changes, more or less randomly. We can’t know why right now — maybe it’s because their brains evolved differently than ours, maybe it’s because of cultural differences, could be a lot of things. But for now, we just need to accept that there’s something different about  »  continue reading …

Current Affairs ... Politics ... Society ...

I’m not the only person these days who wonders if American society is becoming one big dysfunctional family. Or to what degree is it really “one” anymore. “One Nation Under God, Indivisible”? There sure seem to be a lot of divisions these days. Some pundits even talk about the coming of a “New Civil War” or a “Soft Civil War”.

They don’t anticipate another territorial shooting war led by a modern Robert E. Lee or William Tecumseh Sherman, but they do see increasing social and economic polarization that could cause large-scale disruptions in interstate trade, citizen mobility, cultural interchange, and political cooperation between regions and through other ways of dividing people. Today’s version of Bull Run, Chickamauga, Gettysburg, Seven Days and Shiloh may be fought largely on-line, given how important the internet and social media has become to so many areas of daily life. America today has quite a number of ways in which people seem to be dividing into “them versus us” groups. Of course, the big divisor seems to be political beliefs and philosophies (progressives versus conservatives, etc.), but in some ways, it even appears that men and women are preparing for battle!

For instance, we now have a cable TV series that picks up where #MeToo leaves off, i.e. about a female terrorist movement that kills men (i.e. Dietland, which I have been watching this summer). In the original American Civil War, the battles were between the same two governments. In a 21st Century version, the combatants will be different for most every major battle.  »  continue reading …
