For about the first five or six hundred years. Then the carbon cycle, once initiated, drives the climate – as it always does – for the next ten thousand years.
How can anyone still not know this?
No, Milutin Milanković knew it, too. And now everyone knows it except, apparently, you. In particular, the carbon cycles are well understood. And so is the disruption we are wreaking on that cycle.
And over here in Arizona NPR reported that seven of the city’s 10 hottest years have come since 2000. Experts say the Valley’s ‘heat island’ effect and climate change may be to blame… But more ominously, no rain on the whole month of January. The whole west is experiencing a very severe drought and there are already some areas in California where water will be cut off if no rain comes soon.
Yep! “Let’s take the carbon that’s been out of the carbon cycle for a few hundred million years, sequestered deep in the earth since the Cretaceous or before, and dump it into the atmosphere at the rate of more than 30 billion tons of CO2 a year and see what happens. What could possibly go wrong”?
Complete nonsense, and easily shown to be false in the extreme. It’s exactly that sort of pseudo scientific rhetoric that makes all climate proclamations suspect, because seriously, if anyone is that deluded about climate, how can you believe them about anything?
Who was conducting an experiment? I mean, the phrase is nice for a rally full of ignorant schoolchildren, but no experiment in any shape of form.
In what way was it an experiment except in the most tortured of analogies?
30 billion tons sounds like a BIG NUMBER, but since the Earth naturally produces 750 billion tons, i.e. 25 times as much, it doesn’t sound that big. You could rephrase it in a less alarmist way by saying that humans have increased CO2 production by 4%. Heck, 4% may be enough to cause a lot of damage and disrupt all sorts of cycles, but you 30 BILLION TONS would’ve played better somewhere else.
BTW, the other option to the “experiment”, i.e. not burning stuff, is living in conditions you don’t consider even remotely accpetable for your enemies.
Please do. Please show me the scientific evidence that my description of CO2 driving the transition from glacials to interglacial periods is wrong. I look forward to it. I’ll be here. It’s one of the most fundamental basics in paleoclimatology. Denying it implies CO2 isn’t a GHG. You can post your flat-earth theories at the same time as you post your theories about that.
Joanne Supernova, Kid Ljungqvist, and now Freeman Dyson. You’ve hit the trifecta, but keep 'em coming!
No worries, I don’t have the wrong idea. So far on this board, every single thing I’ve seen you post on matters of climate science has been flat-out wrong, and has been shown to be so. Sometimes humorously so. I suppose having you questioning my claims should be considered a compliment.
Tell us again about how water vapor is a climate “forcing”.
You might want to consider the fact that the carbon cycle is a balance, and until industrialization has been absorbing as much as it’s been emitting, which is why CO2 levels were extremely stable for a thousand years before industrialization, and shot up like a skyrocket in modern times. Your bogus numbers rather overlook the fact that in this delicate balance of the carbon cycle, the atmospheric CO2 content has shot up by 37% over the pre-industrial level, putting it definitively at the highest level by far in at least 1.2 million years and more likely the highest level in the last 15 million. It’s at 400 ppm and has demonstrably never exceeded 300 ppm in all the ice age cycles since the MPT 1.2 million years ago.
Yes, but you just posted essentially a video blog from a random physicist with no credentials in climatology, no climate research, no published papers in the field, and who is prone to spouting incredibly dumb shit like " Carbon emissions are not a problem because in a few years genetic engineers will develop “carbon-eating trees” that will sequester carbon in soils". At least with Ljungqvist you have the excuse that he’s actually publishing in the peer-reviewed journals (it’s just that his work is crap and everyone’s known it for quite a while); I literally can conceive of no reason why you’d cite Dyson other than naive, “he’s a scientist, he must know what he’s talking about” fervor. Christ, is the barrel that empty? That sweet bribe money really is sinking in to all the scientists, isn’t it?
