Where did he get a 40,000 year old tree?

OK. So they are trying to explain away warmth in the past when only cars and cow farts cause warming. Science you know.

A fun question that most don’t even think about: If every point in the entire sky contains, at some distance, a star who’s light energy is reaching earth, why is the sky not lit up like daylight even at night? There is an answer, but most people don’t even ask the question.

A supernova within about 150 light years from Earth would severely impact the planet. For that matter a gamma ray burst thousands of light years away would to the same if aimed at Earth. And we thought that asteroids were all we had to worry about. Lol.

Our climate has always changed. It's never been static.

Time to send out a petition to Dem voters stating we need to dedicate our resources to stop all Supernovas

That question was answered by Edgar Allen Poe, who was not only a great story teller, but also an amateur astronomer.

The stars are so far away, that their light has not gotten here yet..............

[Red Badger]

It's all those aliens driving Super Novas...........

SuspiciousObservers.org gives a daily six minute presentation of space weather predictions and how it affects our planet.

Warning, big words:)

That’s only one of the theories to explain Olber’s paradox. :)

Don’t get me wrong. It might be true, but it is really more of a hypothesis than a theory until they can come up with a good way to test it.

Good one

[Red Badger]

Another reason is, that ‘space’ is so clean that the light from distant stars is not ‘scattered’ like in our own atmosphere....................

[Varda]

Look up dendrochronology, it’s mostly not about living trees.

[Red Badger]

That’s why I’m a Mustang guy. Gotta save de Erf.................

A distant star can change our climate, but the closest one has no effect on our climate?

Got it.

[Red Badger]

Well, when it goes nova, it will..................

Warning, big words:)

Worse, big words with consistent interpretations that actually match the available data.

[Pikachu_Dad]

You mean... Worse, big words with varying interpretations that actually match the constantly changing available data.
