seems like YOU don't know what a null hypothesis is.
Until YOU and your cohort prove that a TRACE gas in the atmosphere is causing the climate to change, there is nothing to discuss.
So far NOBODY has proven it.
Hysterical speculations are not PROOFS.
Why all of your CO2 warmers are specifically concentrated on the trace gas is understandable - the dire need to connect something not related to human activity to that activity in order to punish that activity and make money![]()
I don't know why you're laughing, unless it's at your own mindless parroting of what other people say. The fact that CO2 is a trace gas is irrelevant to the discussion. There are plenty of studies that show that Earth's climate would be much cooler, if there were no CO2 in the atmosphere. Therefore, the important factor in the equation is the % increase NOT the absolute increase. Learn some science before making yourself look like a fool again, please. All the hysterical claims are actually coming from the deniers. Their ignorance would be really funny, if it weren't so sad and potentially dangerous to us all.
except the plot of the increase of the temperature depending on the concentration is NOT linear. And actually with increased concentration of the CO2 the warming effect DIMINISHES
According to well understood physical parameters, the effectiveness of CO2 as a greenhouse gas diminishes logarithmically with increasing concentration and from the current level of ~390 ppmv, (parts per million by volume). Accordingly only ~5% of the effectiveness of CO2 as a greenhouse gas remains beyond the current level.
The logarithmic diminution of the effect of CO2 is probably the reason why there was no runaway greenhouse warming from CO2 in earlier eons when CO2 levels were known to be at levels of several thousands ppmv.
Remarkably, IPCC Published reports , (TAR3), do actually acknowledge that the effective temperature increase caused by growing concentrations of CO2 in the atmosphere radically diminishes with increasing concentrations. This information is in their report. It is well disguised for any lay reader, (Chapter 6. Radiative Forcing of Climate Change: section 6.3.4 Total Well-Mixed Greenhouse Gas Forcing Estimate).
The diminishing percentage effectiveness of CO2 as a greenhouse gas is acknowledged by the IPCC
Although the IPCC tacitly acknowledges that this crucial diminution effect with increasing concentrations effect exists, it certainly does not go out of its way to emphasize it. Like the Medieval Warm Period, that they attempted to eliminate with the Hockey Stick graph in 2001, the panel knows that wide public knowledge of the diminution effect with increasing CO2 concentration would be utterly detrimental to their primary message -“man-made CO2 emissions are the cause of climate change”.
The IPCC certainly does not explain these devastating consequences for the CAGW theory in their Summary for Policy Makers. This is because the IPCC is an essentially political organization, that is solely tasked with the promotion and presentation of man-made Climate Change from CO2 emissions, as an accepted and non-contentious fact for world’s politicians.
This inconvenient fact is well understood in the climate science community. It can be accurately modeled using the Modtran program maintained and supported at the University of Chicago.
From the present concentration of atmospheric CO2 at approaching 400 ppmv, only ~5% of the effectiveness of CO2 as a Greenhouse Gas remains.
This can only give rise to a maximum of a further of ~+0.21°C. Thereafter beyond 1000+ ppmv the effect of increasing levels of CO2 can only ever be absolutely minimal even if CO2 concentrations were to increase indefinitely.
It is for this irrefutable physical fact that the widely held alarmist policy ambition
“to constrain man-made temperature increase to only +2.0 °C”
could in fact never be reached, however much more man-made CO2 was emitted.
It is impossible to ever reach the much vaunted policy upper limit of +2.0 °C that has been promoted by politicians as a target upper limit of temperature effect caused by man-made CO2 emissions.
