You don't know that, it's impossible to determine. That is an extremely un-scientific assumption working backwards from the belief CO2 accelerates warming. There is no temporal "high-resolution" temperature data-sets going back 10's of thousands of years with small error bands, let alone millions of years. Unless you have a link to that data? You need a link to a study peer reviewed research paper with actually data. The only people who say this are Michael Mann (Penn State) and James Hansen (NASA). All temperature data we have today before 1940 is extremely filtered with large error bands.


Despite that, the world has been warmer with less CO2. All you have to work with are models that are all wrong so far.

There is empirical evidence of a direct relationship between temperature and CO2. This experiment has been carried out numerous times.

Temperature changes first, then CO2 follows as oceans release CO2 when they warm. There is no 'global' scale 'experiment' lol. Not to mention, Bill Nye tried this experiment and then falsified the data.

So, let's just say for example, global average temperature rate of change is 0.14c/decade from 1980 to 2000. A 20 year period. The fastest that ever existed. Holeee smokes, I got whip-lash it is so fast. Except the last year it has been 0.13c/decade.

What was the rate of global average temperature change from -8120BC to -8100BC?

No, scientists have done experiments with CO2 and temperature and looked at their correlation. Here's a simple one....

Something's fishy about that chart. 1. There's no such place as Muana Loa. It's Mauna Loa. One would think a reputable source would know how to spell places. 2. I would have thought that they would not show assumptions. Where do they get that assumption from? Your source seems to be a blogger or something.

Nah....what gave it away?......the link that says "blog"? [icon_lol2.gif] The spelling in the graph is obviously a mistake, he spells it correctly in the article.....did you not read it? ....or was the pretty picture enough?

the end is coming , 280 billion pension fund in new york is backing shareholder demands for no more fossil fuel backing.

New York pension officials on Monday said they will support shareholder resolutions filed at major banks seeking quick cuts to financing of new fossil fuel development, pushing climate issues to the fore of another springtime shareholder meeting season.

Shareholders should support resolutions filed at Bank of America Corp, (BAC.N) Goldman Sachs Group Inc (GS.N) and four other banks "in order to mitigate the systemic risks posed by unfettered climate change," according to a statement sent by a representative of New York State Comptroller Thomas DiNapoli, who oversees some $280 billion in retirement assets.

also this .

Standard Chartered (STAN.L) said on Tuesday it would end all direct coal financing for clients by 2032, as the Asia and Africa-focused lender tightens up its climate policy.

The London-listed bank, which previously ended new coal financing, said legacy coal financing would also end within ten years, in an update ahead of its annual investor meeting in London on May 4.

Investors will have the chance to vote on the bank's amended climate policy in an advisory vote at the meeting.

lol. You'd think if science can be reviewed, so could spelling. Pretty much a junk chart. There are many reasons it is fishy. Someone did a curve-fit exercise and derived a formula for a specific time period. It doesn't work for any other time period than 1860 to 2010, and it doesn't explain reasons for mid-century temperature drops. Temperature depends on obliquity, insolation, and many other things, not just CO2. Water vapor IS the most powerful GHG and dwarfs CO2. Directly correlating CO2 to temperature is nonsense.

IR absorption is assumed to be logarithmic, and earths atmosphere before man's contribution was already 300ppm, not 0, so there is no dramatic effect adding more CO2. Most IR energy is absorbed in the first 20ppm. The amount of absorption difference from say 300ppm to 400ppm is tiny. Many scientists say CO2 absorption is saturated so more CO2 likely won't do anything. Not all scientists believe CO2 absorbs logarithmically either.

Coming in and out of ice-ages where the temperature changes drastically has more to do with long period phasic astronomical cycles. As the earth cools or warms, the oceans absorbs or releases CO2.

More advances in solar tech .

https://www.ecowatch.com/solar-panel-en ... iency.html
Scientists from the University of Surrey and Imperial College London have achieved an increase in energy absorption in ultra-thin solar panels by 25%, a record for panels of this size.
It is a interesting article i think worth reading myself.

As long as the CO2 concentrations stays above 400 ppm, there won't be any ice ages.
Ancient air bubbles trapped in ice enable us to step back in time and see what Earth's atmosphere, and climate, were like in the distant past. They tell us that levels of carbon dioxide (CO2) in the atmosphere are higher than they have been at any time in the past 400,000 years. During ice ages, CO2 levels were around 200 parts per million (ppm), and during the warmer interglacial periods, they hovered around 280 ppm (see fluctuations in the graph). In 2013, CO2 levels surpassed 400 ppm for the first time in recorded history. This recent relentless rise in CO2 shows a remarkably constant relationship with fossil-fuel burning, and can be well accounted for based on the simple premise that about 60 percent of fossil-fuel emissions stay in the air.

Today, we stand on the threshold of a new geologic era, which some term the "Anthropocene", one where the climate is very different to the one our ancestors knew.

So? Your proof is? Show us the science? It is truly impossible to know, and highly unlikely the additional CO2 will do anything, let alone "400" has anything to do with anything.

....any proof to say not? When has any ice age had 400 ppm of CO2? For the 800,000 years of relatively decent ice core data, not one ice age had CO2 level of plus 400 ppm.
