Overpopulation
It will definitely recover, as long as we’re not around to fsck it up.

I agree that the planet has been very resilient over the past 4.5 billion years, with life even surviving the “great poisoning” of the atmosphere by oxygen about 2.5 billion years ago.
Let’s just say we might fsck things up so much it takes a very long time for it to recover.
Because acidification causes creatures with shells to have a harder time accreting the shell, less carbon in the form of calcium carbonate is extracted from the ocean and locked away as limestone over time. This just compounds the problem because the oceans then absorb less CO2 from the atmosphere than they did before, but stay just as acidic. This leaves more CO2 in the atmosphere, increasing the partial pressure of he CO2, acidifying the oceans further and so on. It’s a vicious cycle. There are other, more subtle consequences of disrupting the Long Carbon Cycle as well.

Yes indeed. A severe disruption of the Long Carbon Cycle I alluded to above could do that. It can have ramifications on geological time scales.

You might be surprised to know that I don’t remember that. 
So what was there before it and which was better?
I use that term ‘better’ deliberately because I am wondering if the only bad thing to come as a result of our induced climate change is the end of the human race, and, in the great scheme of things is that such a bad thing? Some other beings might emerge who can thrive on such conditions which will allow them a couple of billion years to cock the job up too. 
The logic of that sort of thinking is that it really doesn’t matter, well not to the majority of everybody alive today.
Originally mainly water vapour, methane and ammonia really not very nice by modern standards
Somewhat later nitrogen and carbon dioxide dominated.
2.5 billion years ago all life of earth was microbial, simple multicellular organisms appeared maybe 2 and a bit billion years ago but even at the time of the Cambrian explosion 500 million years or so ago there were only invertebrates.
In planetary terms probably not - most species only last a few hundred thousand to a couple of million years anyway.
They better get on with it - various natural processes including gradual increase in the sun’s luminosity mean that Earth will probably be inhospitable to life in about a billion years. While an intelligent species should have enough time to evolve they don’t have billions of years to do so or to cock it up afterwards.
But that’s what’s caused all the trouble isn’t it? What we need is to be a helluva lot less intelligent.
Just realised, that won’t work, it’s farting cows that are at the root of it all. And they aren’t that bright, otherwise it would be us munching away in the fields, while they drove by in their gaseous vehicles.
Feels good to be old, sometimes. 
PS, How did we get here from Rwanda?
Quite what refugees may be thinking.
More like “How the **** did we get to Rwanda?”

Maybe get this thread back on track with how much the Rwandan policy is costing per head.
Rwanda plan to cost UK £1.8m for each asylum seeker, figures show
Despite being in the very first cohort to get an ‘A’ level in the subject, I’m not an economist. However, if we let only existing asylum seekers stay and just gave each a mere £1,000,000 while withholding the other £800,000 of the actual cost, all this government money would flow into the larger UK economy, rather than that of Rwanda.
Or am I missing something/s…?
This is just a distillation of current immigration policy in Not so Wonderful Land
Ooops. Good news for the RoI, no need for asylum seekers to move south, they can stay in NI

So presumably the Republic can now safely send asylum seekers back to the North!
Hilarious (if you’re not a refugee)

Where does that figure come from Dr Mark ?
I didn’t cite a figure, but in a recent test case, a Dublin court refused to send a cross-border refugee back to the UK because there was the possibility that they would be deported to Rwanda, which was not considered a ‘safe country’.
Some might argue that NI isn’t a safe country
So where does the £1.8 million come from ?
Thanks, the figures are mind-boggling.
Given that Labour have already said they’re going to abandon the Rwanda policy from day one the scale of the millions wasted is extraordinary and bordering on the criminal, think of the number of extra NHS staff this could have funded.
