They insist that the science is settled on much of the climate crisis. Let's look at one of those settled factors. How long do CO2 emissions stay in the atmosphere:
NASA is supposed to be pretty smart:
The Atmosphere: Getting a Handle on Carbon Dioxide
https://climate.nasa.gov/news/2915/the-atmosphere-getting-a-handle-on-carbon-dioxide/
Carbon dioxide is a different animal, however. Once it’s added to the atmosphere, it hangs around, for a long time: between 300 to 1,000 years. Thus, as humans change the atmosphere by emitting carbon dioxide, those changes will endure on the timescale of many human lives.

This is usually a very poor source about climate science.
How long do greenhouse gases stay in the air?
https://www.theguardian.com/environment/2012/jan/16/greenhouse-gases-remain-air
The lifetime in the air of CO2, the most significant man-made greenhouse gas, is probably the most difficult to determine, because there are several processes that remove carbon dioxide from the atmosphere. Between 65% and 80% of CO2 released into the air dissolves into the ocean over a period of 20–200 years. The rest is removed by slower processes that take up to several hundreds of thousands of years, including chemical weathering and rock formation. This means that once in the atmosphere, carbon dioxide can continue to affect climate for thousands of years.

This science source says CO2 stays in the atmosphere........forever!
Carbon is forever

“The climatic impacts of releasing fossil fuel CO2 to the atmosphere will last longer than Stonehenge,” Archer writes. “Longer than time capsules, longer than nuclear waste, far longer than the age of human civilization so far.”
The effects of carbon dioxide on the atmosphere drop off so slowly that unless we kick our “fossil fuel addiction”, to use George W. Bush's phrase, we could force Earth out of its regular pattern of freezes and thaws that has lasted for more than a million years. “If the entire coal reserves were used,” Archer writes, “then glaciation could be delayed for half a million years.”

The residence time of CO2 in the atmosphere is …. 33 years?
http://euanmearns.com/the-residence-time-of-co2-in-the-atmosphere-is-33-years/
An important consideration in estimating future greenhouse warming risks is how long CO2 remains in the atmosphere. Here I present the results of a simple mass balance model that provides a near-perfect fit between CO2 emissions and observed atmospheric CO2 using a CO2 residence time of 33 years. This, however, is significantly longer than 36 peer reviewed estimates that cluster between 5 and 15 years and much shorter than IPCC’s estimates of 100 years or longer, hence the question mark in the title.
“A molecule of carbon dioxide, on average, lasts about 100 years in the atmosphere......according to the most extreme IPCC below"

30 of the 38 studies above show that CO2 only lasts for 10 or less years in the atmosphere.
“Since the IPCC’s task is to prove any global warming is due to human CO2 emissions, they decided to proclaim that carbon dioxide was long-lived in the atmosphere – a fabricated assumption.
“They did this despite the overwhelming majority of peer-reviewed studies (and corroborating empirical measurements) finding that CO2 in the atmosphere remained there a short time. Literally, a fabricated assumption, driven by political agenda, became a cornerstone of fraudulent climate model science. As a result, billions spent on climate models that are unable to predict climate with any accuracy…

metmike: There's alot of debate and different opinions on this one. The carbon budget involves interactions between so many things. Common scientific sense tells one to question that 100 year figure that the IPCC uses, represented by the read line above.
The earlier sources, in fact, the majority of scientists, before climate science was hijacked have found that the residence time of CO2 in the atmosphere to be much less than 100 years.
Note the red line above, the one used by the IPCC goes out to 100 years and many other scientists BEFORE climate science was hijacked, pretty much agreed on something that was just a fraction of that. ....around 10 years or less. (30 out of 38 of them).
However, after climate science was hijacked, sources came out with 200, 300, 1,000 and even 1 million years for the amount of time that CO2 stays in the atmosphere. Those are all political estimates masking as science............just like the entire climate crisis is.
So the so called settled science tells us that CO2 emissions from burning fossil fuels could last from anywhere as short lived as 5 years to possibly as long as half a million years.

In recent years, former Vice President Al Gore has been joined by President Barack Obama and Secretary of State John Kerry as America’s leading Doctrine of Certainty campaigners. Following Obama’s assertion in January’s State of the Union address that “the debate is settled,” Kerry told Indonesians last month that the science backing what he called “the greatest threat that the planet has ever seen” is “something that we understand with absolute assurance of the veracity of that science.” Kerry concluded that climate science is “simple” and “not really a complicated equation.”

We can add a dozen+ new characters to that paragraph above. Biden, Bernie, AOC and many more telling us with certainty that we have a climate crisis, will lose the planet in less than 10 years, will see coastal cities under water before 2030. They've been wrong for over 3 decades and their absurd predictions don't even make sense when the planet is massively greening up and asking for MORE not less CO2.
