Look pal. We can explain it to you (ad nauseam) but we can't understand it for you...We're gonna get hit with more global warming today

There has been a big bump in sea and surface temps in the last year that scientists are still trying to understand.Well maybe theres a tipping point period in every ice age - it just trickles along with hardly any movement then gathers pace at the end of the cycle. we could blame that on industrialisation or it could be just natural. Theres no way of knowing for sure. And who knows how to get it to top it back - or even if we can.
There was that recent news story where all the big ships crossing the atlantic were using cleaner fuel and carbon cleaners in the stacks and this not creating thos big smoke plumes. Then they realised that those big smoke plumes were actually reflecting heat back into space - and now the smoke plumes are gone the oceans are absorbing more of the heat. Who could have predicted such a thing?
No, we definitely know that the 1.5ºC warming we experienced last year is from humans.At the end of the day we will never know if the reason is man-mad or natural.
We really know? And its not a natural tipping point? How can we be so sure? Isn't there a small possibility that it could be part of the natural cycle of life?No, we definitely know that the 1.5ºC warming we experienced last year is from humans.
Yes, we know with very high confidence level.We really know? And its not a natural tipping point? How can we be so sure? Isn't there a small possibility that it could be part of the natural cycle of life?

So is death, but you don't want to bring it on earlier than natural by repeatedly smashing bricks into your head.multiple ice ages prove changing climate is part of the natural cycle of life
Just like it is now - when the natural warming reaches a certain point the glaciers melt, the ocean salination changes, currents change and all this speeds up the melting of the north and south polar ice, which then increases the amount of fresh water in the oceans... and the cycle continues. This is a tipping point that could be entiredy natural... or caused by humans.Yes, we know with very high confidence level.
Its pretty easy to prove.
Name the natural tipping point that you think has warmed the planet about 1.5ºC in 100 or so years.
If its human caused then we can change human behaviour and fix it before too many tipping points are reached.Just like it is now - when the natural warming reaches a certain point the glaciers melt, the ocean salination changes, currents change and all this speeds up the melting of the north and south polar ice, which then increases the amount of fresh water in the oceans... and the cycle continues.

However IMO id say arguing the cause isnt really useful.
Maybe we can fix it by reducing human emissions but maybe we have also passed the point of no return and maybe its too late.
In the hopes that we can fix it we should be focusing on what it would take to reverse it. BUT just like the ships and their smoke clouds we have to be careful that we dont try fixing it and in doing so make it worse.
#1 - Volcanos.If its human caused then we can change human behaviour and fix it before too many tipping points are reached.
But clearly its not 'natural' because you can't name one natural mechanism that would have warmed the planet 1.5ºC.
8 years ago Bloomberg posted a site answering all those questions and charting their influence on the climate. I think its behind a paywall now, but its still up and the numbers aren't that different.#1 - Volcanos.
#2 - Cows farting. Although I get it we bred way too many so yeah thats probably human made.
But Volcanos def contributed to it.
#3 - El Nino. Is that natural or man made?
#4 - Increases in Solar radiation. I think thats natural.
#5 - Changes in earths orbit. Again i dont think humans did that. Even with all the obesity - I guess if all the fattys are on one side of the planet that could throw it off kilter maybe...
to be fair I'm not saying that humans didnt create most of it. But theres definitely at least more than 1 natural cause.
But enough to make a difference to the natural cycle of things? Thats whats debatable.
And at the end of the day. Maybe we only sped up the cycle by a couple of hundred or thousand of years. But it was coming anyway and I doubt we can change it back anytime soon. So we better get used to it.
C02 is 420 parts per million in the atmosphereMaybe we can fix it by reducing human emissions but maybe we have also passed the point of no return and maybe its too late.
When the concentration was that high the global temperature was at a thermal maximum.C02 is 420 parts per million in the atmosphere
historically that concentration has been much higher 2000 to 7000 parts per million
nature cycles 50 X the amount of CO2 humans produce
there is no climate emergency
believing humans can control our extremely complex climate system is absurd and hubris
I didnt see any sea level rise in that twitter thing - what was I missing? All I saw was a village grow up.... sea stayed where it was - I wouldnt say it was devastating.The sea level rise is just crazy. I dont see how we're gonna survive the next few decades
that's the pointI didnt see any sea level rise in that twitter thing - what was I missing? All I saw was a village grow up.... sea stayed where it was - I wouldnt say it was devastating.
