General global warming / climate chage discussion

7899 About 2C, even after accounting for CO2 fertilization effect, and before accounting for increased drought frequency/severity. I think there is low confidence for that statement.  Because: ⋅ Assuming 2C is the global, annual average, what we really need to know is the increase in the ...

Asteroids, meteors, and meteorites

Another nice meteor recorded shortly after true midnight last night: Seen from Harestua near Oslo.  It appeared above the northern horizon and crossed nearly the entire sky disappearing towards the southeast.

Science and Astronomy Questions

7864 Could this knowledge somehow be used in exoplanet searches, by looking for these rather slight spikes in brightness of the dayside of these planets, to see if they also have high altitude ice? No, since these flashes, according to the article, only happen when the probe (or observer) has the s...

Qr Bbpost The underlying rules are the same.  If there is a mechanism that selects for certain traits, those traits become more prevalent with time.

Evolution continues, but the question is to what degree the natural environment will direct what the selectable traits are.

7668 Consider the Tibetans.  They did not evolve to cope better with high altitude by dying much more often (even if they probably did die more often).  They adapted because individuals who had traits that made them marginally less likely to die were marginally more likely to propagate those traits...

But natural selection in a human population now only happens due to major genetic flaws.  He's assuming that Martian humans will have a very high mortality on Mars, probably more than what will be found acceptable for establishing a Martian colony.

Science and Astronomy Questions

Yes, nature finds a way, which is why many trees have figured out how to shed leaves and regrow them.  So a monthly cycle could have given a quite different type of trees. 7438 I also don't think evergreens have much trouble dealing with a lot of snow, in a sense of withstanding the weight. They've ...

7420 Even photosynthesis should be fine with the seasonal loss of sunlight -- it already manages this in the polar winters which last a lot longer. I wonder if there then would be deciduous trees.  There hardly would be enough time to shed and regrow leaves.  If there only are evergreen trees, they...

The moon landings were all staged.  They even went to such lengths with the cover-up that they filmed everything on location.

Unusual weather

This last winter season has just got weirder and weirder here in Oslo.  The skiing season got an early start with a decent (25 - 30 cm) snowfall 4th November, but after that, hardly no new snow fell until the middle of April when most snow below 400 m elevation had melted.  Most of the snow has fall...

I guess the fate of the universe is relevant, if we find a way to travel 99.99999...% of the speed of light.  It would be good to know what the destination would look like.  But this is mainly a question of knowing the universe.

The Future of Humanity & Intelligent life in the universe

A common concern people have about AI is that at some point AI will surpass human intelligence generally, and then AI will simply improve itself exponentially and humans become irrelevant and are supposedly doomed.  They say that we need to think about this now and find a solution before this happen...

General global warming / climate chage discussion

7265 I wonder how coral reef bleaching (the destruction of the great barrier reef over the past 2 years) and the migration of infectious agents further north with climate change will factor in. Yes.  It's a bit Deja vu, though, for those remembering the forest dieback scare around 1980.  It was a h...

General global warming / climate chage discussion

7240 it seems like today there really is a deeper understanding of the universe, compared to past generations. Of course.  And we know for sure that we're missing something, since we can't explain the subatomic reality in terms of the larger scale reality or vice versa.  There is no direct evidence...
