What 400 ppm of CO2 in the atmosphere looks like

Well, Y2K really DID have the potential for a lot of systems to fail

No, it did not. Countries such as Italy, Russia, and South Korea had done little to prepare for Y2K, but even there nothing happened.

Tom J, I like your thinking.

Good point Rodger. The absolute level of H2O increases, but the ratio of H2O to CO2 decreases. But I’m not an expert and these are very generalized statements. As you can see from Robert’s post, different varieties of plants (ie. species) respond differently. Some plants are susceptible to CO2 poisoning. Not all plants even use the same photosynthetic process (C2, C3, C4). And most importantly, CO2 obviously doesn’t just effect photosynthesis. What it does to the climate in its (climate’s) totality is what’s important. We can’t simply say more CO2 is good for all plants under all circumstances. JP

Okay all, it is important that we all keep ourselves clean. We do not want any hints of a scandal. We constantly reveal the scientific errors of the warmists, so we must stay beyond evaluation.
Sooooooo, what are these rumors that Anthony’s dog, supposedly named “K..;.”, or something similar. Are the rumors true that “K….” has been named the most knowledgeable scientist at the Union of Concerned Scientists?
Are the dogs taking over at UCS?
(Oh. it used to be called “Union of Confused Scientists” before K…. joined….)
Too funny.

Higher levels of carbon dioxide also make plants more drought resistant.

Well, Y2K really DID have the potential for a lot of systems to fail — but people mobilized, lots of old COBOL programmers went to work, “year” fields in databases and software were expanded to four digits, and it ended up having virtually no impact at all (although I did convince my wife to install a 20KVA natural-gas generator in the backyard “just in case” :-). …..”””””
Surely you don’t imagine that there were enough people and businesses, or infrastructure elements, that were so locked into the day’s date or time on some computer, that anything that was actually “done” about Y2K really made any difference.
In the Microsoft part of the world, that largest and most unrobust computer virus, known as “windows”, is so buggy, that people are used to it going down daily, and M$ will paste a new layer of band aids on it twice weekly, so nobody actually depends on it to make any critical decisions.
Y2K was more media hype, than any real threat to anything. My computers are all turned off, unless I am actually typing something, and they are all hardware disconnected from any network, including the internet, unless I am actively searching for something, and I disconnect the moment I find what I want or if I do not.
The mongrel on the carpet, was more hazarded by fleas in the mat, than by Y2K

All of you are wacko… plain wacko. Flat-Earther wacko. Sea levels are already rising..”

Sea levels have been rising for thousands of years. There’s no acceleration evident today. Have you taken land subsidence into account? Have you even noticed charts of where it’s slowed?
You seem utterly convinced that man-made CO2 (still a tiny trace gas in our atmosphere at 0.0397%) is going to burn the planet to hell tomorrow. Of course, when it comes to doomsayers, it’s always tomorrow, next week or in the future. That just continues until the next fearmongering “fad” comes along to be likewise always “predicted” in the future. Some questions for you:
Every exhalation is around 4% CO2 (40,000ppm – atmospere now 397ppm). How is it you don’t burn your tongue in the sun when you exhale that ENORMOUS 4% of CO2?
How is it that delicate aragonite corals evolved when CO2 was some 20x higher than today?
With CO2 so much higher in the past and you expecting a LINEAR scale to CO2 heat trapping effect, why was there never a runaway greenhouse, ever?
How is it that CO2 was many times higher than today even during deep ice ages?
You understand that CO2 is necessary for photosynthesis and farmers actually pump CO2 into their greenhouses to increase yields, right?
Do you know that Viking graves in Greenland now are in permafrost – something you can’t dig without hydraulics? Vikings colonised and farmed Greenland 1000 years ago, why did they leave 300 years later?
The Little Ice Age is documented in paintings from the 1600’s where the Thames and Hudson rivers froze 10ft thick and the locals held fairs on them. Are you aware of this at all? Are you aware this was caused by the “Maunder Minimum”, a time when very few Sunspots and Solar activity occurred?
Do you remember when an imminent “ice age” was predicted in the 70’s?
Are you aware that Global temps reduced between the 40’s to the 70’s?
Do you understand the cycles of the oceans (PDO, AMO, ENSO) and their impact from warm to cool and back again over regular decadal scales?
Why is it that in a desert, you can fry during the day and freeze at night, but not in the tropics? What magical atmospheric component is missing in a desert to cause this and therefore, is CO2 actually trapping any catastrophic heat at all? A clue – notice how the night is usually warmer when it’s overcast?
Have you noticed that CO2 continues to climb but Global temps have flatlined for the last 17 YEARS? Why the disconnect?
Are you aware that CO2 temp impact is on a logarithmic scale and not a linear one? This means the more CO2 you add, the less impact it has?
Do you understand that warm water outgasses CO2 – try opening a warm and a cold bottle of soda water. Do you now understand that the oceans could never become “acidic”, considering their pH ranges from 7.9 to 8.3, depending on where you measure it and, that the pH scale is also logarithmic?
How do you explain the findings of ancient tools and tree stumps under retreating glaciers?
Have you seen the geological records that show CO2 rising AFTER temp rises by some hundreds of years?
Have you discovered Milankovich Cycles – how the Earth has cyclical wobbles in its orbit being tugged on by other planets causing major changes in our distance from the Sun?
Have you discovered that on very regular cycles, the Earth suffers a major ice age about every 100,000 years lasting many times longer than our current interglacial? Do you think that’s connected to my previous question?
Why is it that some 90+% of species live around the Equator?
Figures are readily available to show winters kill more people than summers – have you looked into them and why do you think retirees look forward to living in warmer climates?
Are you aware that the Arctic ice extent is now the same as the 1979 annual mean? Do you really think it’s going to be “ice free” at all this NH summer?
Does it make sense that “climate scientists”, being largely (if not totally) government funded, need to continue blaming Man for CO2 ills since governments want to tax us on it and, if they say it’s not, they’ll lose their job?
Mountinman, have a good look around and you’ll find there are more questions that require answering before spouting for certain that Man is to blame for climate change. It’s been doing it for billions of years and will continue to do so. There’s NO peer-reviewed study out there that can scientifically and unequivocally state that they can filter out Man’s warming signal from the natural noise.
If you keep believing point-blank the government and the lamestream media, you’ll look like a fool (you’re repidly getting there) and have a lighter wallet to boot. Don’t be a puppet or a parrot to them. Remember this:
“When a well-packaged web of lies has been sold gradually to the masses over generations, the truth will seem utterly preposterous and its speaker a raving lunatic”.

Ricin (pron.: /ˈraɪsɪn/), from the castor oil plant Ricinus communis, is a highly toxic, naturally occurring carbohydrate-binding protein of the type known as lectins. A dose the size of a few grains of table salt can kill an adult human.[1] The median lethal dose (LD50) of ricin is around 22 micrograms per kilogram (1.78 mg for an average adult, around 1⁄228 of a standard aspirin tablet/0.4 g gross) in humans if exposure is from injection or inhalation.[2] Oral exposure to ricin is far less toxic and a lethal dose can be up to 20–30 milligrams per kilogram.

I was working in IT support back then. Had to stay up all night!
Great TV. Saw Tony Blair physically grab the Queen and tried to make her dance!
Talk about auld lange syne……….”””””
So would somebody please put in quotation marks what if anything I actually said, in relation to whatever this post by whoever it was is.
