At an outdoor test site in Italy, CO2 concentrations vacillating between 1,000 and 750,000 ppm have no more or less an effect on local temperatures than a nearby site with stable, ambient (<400 ppm) CO2 concentrations.
Mofette fields are “natural carbon dioxide springs” that allow us to observe the effect that a 100% (1,000,000 ppm) CO2 concentration has on ecosystems, temperatures…even spiders (Balkenhol et al., 2016).
Temperature changes over the CO2-spewing Bossoleto spring (pictured) in Tuscany, Italy, were measured over the course of a few days in the early 1990s by Gardingen et al., 1995.
The scientists observed the site’s CO2 rises daily from 1,000 ppm at 3:30 p.m. in the afternoon to 750,000 ppm by 7:00 a.m. the next morning.
The temperature changes associated with these extreme CO2 variations are about 33°C at 3:30 p.m., falling to 23°C by 7 a.m.
More specifically, when the Sun rises above the horizon, temperatures abruptly warm by 10°C, and then CO2 rapidly falls from its morning peak (750,000 ppm) to its afternoon nadir (1,000 ppm).
At a nearby site, where CO2 levels center around an ambient 360 ppm (1992 levels) throughout the day, Gardingen and colleagues observed temperature changes to be effectively identical to the Bossoleto site: 23°C at 7 a.m. and 33°C at 3:30 p.m.
In other words, the CO2 concentration – whether a stable 0.036% throughout the day or a wildly fluctuating 1% to 75% over the course of a 24-hour period – had no detectable effect on changes to the surface temperature.
This real-world temperature-CO2 experiment would appear to show CO2 varies in response to environmental factors, but it does not appear to causally affect temperature changes.

February 13, 2017 Chemistry Expert: Carbon Dioxide Can’t Cause Global Warming
Scarcely a day goes by without us being warned of coastal inundation by rising seas due to global warming. Why on earth do we attribute any heating of the oceans to carbon dioxide, when there is a far more obvious culprit, and when such a straightforward examination of the thermodynamics render it impossible.

Let’s not forget the greening that follows.
Apr 26, 2016 Rising CO2 Levels Greening Earth by NASA Goddard
From a quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study published in the journal Nature Climate Change on April 25. The greening represents an increase in leaves on plants and trees equivalent in area to two times the continental United States.

a negative carbon budget?

“The present project investigated the influence of increased atmospheric CO2 concentration on spiders as representatives of above-ground organisms by means of pitfall traps in three mofette fields, differing in habitat conditions”
Is this a temperature study or a study of the impact of high co2 on spiders?
I would say the primary study is the effect of CO2 concentrations on spiders. The actual temperature part is pointless in an open system where co2 is added to system from an external source. The added CO2 would have a different temperature to actual air temps, as it coming from an underground source. Only thing it shows is we don’t get Venus like temperature even with a hundred fold increase in CO2 temperature.
