At 240 PPM? No, more like the end of the last glaciation. There are other climate variables (like the sun ). The Ordovician period was full glaciation with co2 levels at least 6000 ppm.
This is an interesting chart showing co2 forcing. Antarctic ice supposedly forms when co2 is under 450 ppm. We will be over that level in 15-20 years. Let's see how warm it gets in Antarctica where the mean annual temperature of the interior is −57°C (−70°F).
What are you talking about? The Earth's atmosphere today is about 0.04 % carbon dioxide...... Remove 0.04 % and you have no CO2...CO2 moderates earths temperature and without it earth would soon be a big snowball.

try again. high CO2 levels do not always equate to high temperatures;
Unbelievable....I said nothing about high CO2 levels....My question was about no CO2 at all.....Over the past 400,000 years, CO2 concentrations have varied regularly from about 180 parts per million during the deep glaciations of the Holocene to 280 parts per million during the interglacial periods. Can you imagine what the impact would be with no CO2 at all, or are you denying the well known effect that CO2 has on climate?
What they say in their article is not what their graph depicts.
"In fact, if you look back at the historical record in detail, it becomes clear that average summer maximum temperatures in Salt Lake City were about constant from the 1870s to the 1920s, after which they increased rapidly from the 1920s to the 1960s, and there has been no significant trend since the early 1960s."
What the graph actually depicts is an increase in temperature from the 1920s to late 1930s, then a decrease in temperature from the late 1930s to 1980, followed by another increase in temperature since 1980.
That is also consistent with NASA's data that shows a very similar pattern of warming and cooling cycles. Currently, we are already in another 35-year cooling cycle.
More importantly, the graph depicts wide fluctuation in annual temperature. I suspect that even a trend line analysis would not be conclusive, given the wide annual variations.

Humans do affect temperature and atmosphere on a local basis. You see that on the weather reports - the temp is usually a little warmer in the urban populated areas than the suburbs. Pollution is a little worse in the populated areas.
However, there is no large scale human effect on the environment.
Mostly I think the temperatures rise significantly higher in cities that tend to be dominated by "liberals." This is because of all the hot air that escapes their lips.
Geez, I wish you ideologues would learn a little science. CO2 IS a greenhouse gas, just not the most important one.
Water vapor, Methane. CO2, Nitrous Oxide, Ozone, CFC's are ALL greenhouse gasses. Methane is actually more powerful that CO2, but because it exists in such low concentrations it is not particularly effective at the moment. Water vapor remains the most abundant thus more effective greenhouse gas at this time.
It does no good for our side if the arguments are false.
So says the EPA, a well known bastion for liberal nonsense. These are the people who desire to seize as much private property as they can at every opportunity. Within the last couple of years they even lost a Supreme Court case involving their effective seizing of private property without even a trial in court.
Wonder why I say that the liberal left agenda is to seize control of the government and reduce us all to slavery?

I'm hoping the climate will change to winter soon.
