Lol Old Sol is a mid aged star... over the next billion years it will increase in luminosity by almost 10%. Then it will begin fusing helium, and start expanding... It'll burn helium for another couple of billion years but then it will begin to expand so vast that it will first engulf the orbit of Mercury, Venus some hundreds of million years later, to probably knock on Earth's doorstep. It will be a cooler red giant by that time, but ... "cooler" is a relative term. Earth will be a cinder. Glowing in a lifeless infrared thermal radiance. And, as the expulsion by the giant phase start sas it will impose a lot or orbital drag; Earth's could decay and end up inside the envelope of the sun's our layers. The end. We really are approaching the late innings of this planets nurturing life potential. Demarcated as the "Goldie Locks Zone" ... it's the orbital distance that is ideal for liquid water, and a planet's only magnetic field protecting it from harsh radiation from space ...et al, allowing all that is under the sun and our history, including Trump, to have ever existed ... LOL. But, the hell on Earth he brings - or is trying to - will get here without him, given enough time. When that GLZ migrates out and leaves Earth behind, we'll convert the oceans to WV and that'll put us in a Venus predicament. Some models have Earth like Venus in a couple billion years. But, folks need to be aware that within a single life time or two, none of that matters. The "ecological domino collapse" scenario is not just plausible, due to rate of climate change surpassing biological adaptation rates. In fact, that can happen while the Earth is still technically capable of supporting complex life, including humans. The codependents is more than a first order derivatives. There are transitive/non-linear stresses that are 2ndary and tertiary ... these are the dominoes. And they are indirectly still needing the total vitality of interrelated health of each input into the system. This can all happen quite swiftly... leaving a period when the Earth could still have breathable air, albeit warmer, with oceans still lapping at shores ... barren otherwise. Life in the ocean is not unaffected by all this. Deep ocean perhaps would survive the CC attribution death waves... the other thing is, there's also ecological collapse going on because of the chemicals we use-- they are just as horrible as climate change is and humanity has started a new mass extinction event even without climate change.

By the way, did you know a 9th planet the size of Neptune might have been discovered? Link to comment Share on other sites More sharing options...
