Not so fast . Carbon dioxide levels have nothing to do with global warming,or climate change.
The science is far from settled.

Re: Global warming-maybe not so fast if Maunder Mimimum Coming and if representative of mid 1600's to early 1700's NASA latest.....beginning to shift their story to cooling......paper released last week.
science.nasa.gov

Summary....."NASA reports this week that we may be on the verge of another Maunder Minimum (a period with an unusually low number of sunspots, leading to colder temperatures):

Much has been made of the probable connection between the Maunder Minimum, a 70-year deficit of sunspots in the late 17th-early 18th century, and the coldest part of the Little Ice Age, during which Europe and North America were subjected to bitterly cold winters. The mechanism for that regional cooling could have been a drop in the sun’s EUV output; this is, however, speculative.

***

The sun could be on the threshold of a mini-Maunder event right now. Ongoing Solar Cycle 24 is the weakest in more than 50 years. Moreover, there is (controversial) evidence of a long-term weakening trend in the magnetic field strength of sunspots. Matt Penn and William Livingston of the National Solar Observatory predict that by the time Solar Cycle 25 arrives, magnetic fields on the sun will be so weak that few if any sunspots will be formed. Independent lines of research involving helioseismology and surface polar fields tend to support their conclusion.

NASA explains that interactions between the sun, sources of cosmic radiation and the Earth are very complicated, and it takes an interdisciplinary team of heliophysicists, chemists and others to quantify what is really going on. And the Earth’s climate is also affected by cosmic radiation.

So – even if NASA’s prediction of a period of an unusually low amount of sun spots is proven correct – it is hard to know whether that will lead to a large or small reduction in temperature trends."


As an aside, I came across the work of Dr. Theodor Landscheidt en.wikipedia.org a few years back
"New Little Ice Age Instead of Global Warming?" published in 2003 shortly before his death.
landscheidt.wordpress.com
In revisiting the topic, I find other researchers have "picked up the planetary balls" with additional research tying planetary cycles to sunspot cycles.
Specifically the recent work of Carl Smith and others is captured here landscheidt.info .....very interesting reading....
....their conclusion.....it likely is going to get progressively colder over the next 20 years .....not a Maunder Minimum as Landscheidt predicted and NASA now talks about above....more likely a pseudo Dalton Minimum....????

You made a mistake in referring to "balance". There has never been "balance". Adding CO2 to the atmosphere is not unbalancing anything. It does increase the CO2 and the flow to other locations such as life and sediments, but those were not in balance before the CO2 was added. CO2 had been depleted for hundreds of millions of years down to a homeopathic amount [though it bounced up and down during that decline]. Some has been added back. Not much, but some.

If anything, the "balance" has been restored a little bit by the intervention of people. Gaia obviously invented people just in time to do that. Go Gaia. It's peculiar that Greenies would try to stop Gaia doing what Gaia does.

And don't forget to add urban heat islands to the mix...

en.wikipedia.org

As you say feedback loops and scale of change yet to be determined. .. I've seen big changes in Florida's climate from 15+ years ago. I would have laughed at the notion of climate change even a decade ago..
