Climate Change, Whirligig Icebergs

Climate change is still in the news. Don't worry, I won't rant about impending doom, or say that Earth's climate isn't changing.

This planet's climate has been changing for several billion years. I'd be astounded if it stopped changing now.

How much we know and understand about our own past, and Earth's, is also changing. I'll be talking about that, and why I'm not upset that we're learning.

I'll also take a look at (real) climate change, why I think we are not doomed, and choices we must make soon. "Soon," in this case, is somewhere in the next millennium or so. My opinion. We really do not want to make these decisions hastily....

Mars: Leaky Red Planet

What we're learning about Mars, and a new type of really small spacecraft, reminded me of earth, air and kilts.

Also pharaohs, Thomas Paine, and Lord Kelvin. By then I was running out of time to write something more tightly-organized.

I figured you might be interested in some of what I have written. On on the other hand, maybe not. So I added links to my ramblings before and after what I said more-or-less about the science news, and figure you can decide what's interesting and what's not.

Bogs and Bison

The good news is that bison are back in Banff, and Britain's bogs may bounce back, too. Keeping wetlands wet isn't what many folks had in mind, back in my youth.

But as I keep saying, we've learned quite a bit since then....

...This post's afterword is a quick look at how folks have perceived natural resources, plus a bit about pessimism and being human....

Urban Evolution and Big Brains

Life, and evolution, has been happening for quite a while. Cities are new, but the same processes happen there; with slightly different results. We're learning how urban environments affect critters, and are piecing together more of humanity's story....

...I see no problem with believing that God is creating a universe that's following knowable physical laws. That's just as well, since it's what we're told to believe....

Near-Earth Asteroids

Scientists spotted 2016 UR36 days before it passed by Earth. "Killer asteroids" headlines notwithstanding, we knew it would miss our planet by a comfortable margin.

Sooner or later, though, something big will hit Earth: again. We still can't prevent that, not yet.

Earth Overshoot Day and Pollinators

Australia's Earth Overshoot Day happened earlier this week. It used to be called Ecological Debt Day, involves a lot of math, and assumes that Earth's glaciers, deserts, and oceans, are pretty much all the same thing. The basic idea, that we shouldn’t waste resources, isn't silly, and I'll get back to that.

Some other scientists say that we should pay attention to pollinators. I think they're right.

Can I Be a Good Steward and a Good Samaritan?



Another week of life usurping my time with the Navigating Your Finances God's Way  and our small group gathering - I guess Easter evening not the best time for such things.  We are scheduled for later this week - so I better get caught up on my reading!!   Though, truth be told, it is not really difficult for me to be drawn into this study.  The text, scriptures and questions are not only engaging but also RELEVANT!

This week is GENEROSITY ... as Jesus teaches, "It is more blessed to give than to receive." (Acts 20:35)  I have often thought of myself as generous to a fault, it will be interesting as we move through this chapter if others would see me that way too.  It will also be interesting to discover if my generosity has played any role in where we are financially - both to the positive and the negative.  Without reading a word - I am going to speculate on something.   My giving when done with the purest of intentions and through the counsel of the Holy Spirit - I would imagine have been a blessing to us; just as when my giving has been purely for show or recognition, while it surely blessed the receiver was not a blessing to me or our family's financial well-being.  Read more on how to be a balanced giver?

The Halloween Asteroid: 2015 TB145

Asteroid 2015 TB145 won't hit Earth, but it will be only slightly farther from us than the Moon at 1:05 p.m. EDT, 5:05 p.m. UTC, October 31. I've talked about asteroids, Earth Time, and why thinking ahead makes sense, before....

...Fifty years ago, we probably wouldn't have noticed an incoming asteroid until very shortly before it hit. Even if we did, there wouldn't have been much we could do, apart from praying — and that's another topic....

Setting Earth's Thermostat

Events like the Pinatubo eruptions of 1991 happen about once a century — on average — roughly.

Some scientists say that next time there's a Pinatubo-scale eruption, we should deploy a fleet of instrument-carrying aircraft, balloons, and satellites: to see exactly what happens when sulfur dioxide and other chemicals get dumped into the upper atmosphere.

We know that the stuff causes regional and global climate changes: but we don't know exactly how the process works.

There's more than pure scientific curiosity behind wanting this knowledge. Earth's climate is changing, which is par for the course: but we're at a point where our actions can affect climate.

The job at hand is leaning how Earth's climate works, how it changes, and what causes the changes. Then we'll decide what to do about that knowledge....

Environmentalism: Using the Brains God Gave Us

I remember the 'good old days:' seeing house-size gobs of suds floating down the Mississippi; and a year when my eyes stung, except on Sundays, when the city's air cleared up. I don't miss the 'good old days.' (April 11, 2011; November 10, 2010)

I was already concerned about pollution, wildlife management, and other environmental issues, when the first green Earth Day flag went up in 1972.

At the time, I was glad that environmental awareness was spreading; and thought that some 'environmentalists' had more enthusiasm than good sense. I'm still glad that more folks started 'thinking green;' and think that Captain Planet helped make environmentalism look silly.

Sadly, some folks still seem to have learned their facts about science and ecology by watching Indiana Jones and the Kingdom of the Crystal Skull and Tentacles.

Delicate and Fragile as Cockroaches and Thistles

The good news is that some scientists, at least, have apparently realized that an ecosystem that's survived at least 3,700,000,000 years. That's not bad for life on a planet orbiting a slightly variable star; despite occasional comet and asteroid impacts, regional volcanic activity, and epochs of continental glaciation; is hardly "fragile."
"Environmentalism is undergoing a radical transformation. New science has shown how long-held notions about trying to 'save the planet' and preserve the life we have today no longer apply.

"Instead, a growing chorus of senior scientists refer to the Earth with metaphors such as 'the wakened giant' and 'the ornery beast', a planet that is 'fighting back' and seeking 'revenge', and a new era of 'angry summers' and 'death spirals'...."

Lowering Costs on the Earth-to-Orbit Run, Preparing for Incoming Asteroids

Getting scared silly by the latest doomsday prediction is silly. So is ignoring real threats.


(Copyright M. Ahmetvaleev, via NASA News, used w/o permission.)

The Chelyabinsk meteor didn't kill anyone. Only 1,100 or so folks needed medical treatment: for injuries ranging from cuts and bruises to a broken spine. Next time, we may not get off so lightly. Now is a very good time to start getting ready for an incoming asteroid....

Apart from Space Shuttle fleet, now out of service, and recoverable capsules like Space-X's Dragon, launch vehicles are still a single-use technology. That makes getting into space very expensive.

A decade from now, we'll probably see shipping rates go down: dramatically, I suspect.

Reaction Engines Limited's Skylon is scheduled for a test flight to the International Space Station in 2019. Quite a few other spaceplanes are in development, including: DRDO/ISRO's Avatar; Sierra Nevada Corporation Space Systems' Dream Chaser.; and JAXA's HOPE-X.

Any one of them may run into insurmountable obstacles and not fly. But I'll be very surprised indeed if none lead to an economical ferry service to orbit.
