So? Your proof is? Show us the science? It is truly impossible to know, and highly unlikely the additional CO2 will do anything, let alone "400" has anything to do with anything.
....any proof to say not? When has any ice age had 400 ppm of CO2? For the 800,000 years of relatively decent ice core data, not one ice age had CO2 level of plus 400 ppm.
The last 500 million years have seen no relationship between CO2 and temperature. Where do you get 400ppm from? Why would anyone care about 400ppm and not 395ppm? The amount of CO2 in the air has been declining for a long time, so no recent proxies would show more CO2.

Obviously there is no science behind a comment like "whose to say it isn't!". That basically sums up the modern eco-terrorist and climate science movement - no science needed.

There is little to no relationship between temperatures and CO2 over the last 500 million years and CO2 was 2000, 3000, 4000 ppm.

Even the current interglacial has increasing CO2 while decreasing temperature.

Why go back 500 million years?....that's just pure guess work. The only reliable data goes back 800K years and there was never a period during that time period where CO2 exceeded 400 ppm. It's no big deal about the figure 400 ppm, it's just that during the last 800K years the average CO2 level was 260 ppm so 400 ppm is just a convenient threshold to say that we will never see another ice age as long as the CO2 remains above 400 ppm because Earth will never approach the start of another glacial period as long as the heat trapping gas stays above 400 ppm.

Edit to add: You're still using misleading graphs to further the narrative, you know what I mean because we've already discussed this.

Science is hard work and develops over time. If you don't like peer reviewed journal articles or what you consider to be "misleading" graphs in them you can probably ask the science journals to retract such articles so long as you can provide evidence they are wrong.

There are many proxies, not just ice cores. CO2 has been 300ppm or lower for the last 800,000 years, so what. 400ppm doesn't mean anything at all as to what will happen in the future, considering 400ppm didn't do much in the millions of years past as temperatures didn't follow CO2 levels. 400ppm is no big deal, but earth will never see another ice age? lol. You keep saying that without any evidence. Climate is dependent on many more things than CO2, and CO2 might be pretty minor. The problem with CO2 is that there has always been at least 260ppm, and 400ppm doesn't do much more than 260ppm because most of the absorption happens in the first 100ppm.

It doesn't matter if the articles are peer reviewed going back 500 million years because that's just pure guess work. There is not one shred of evidence to back up the guess works. Myself, the only reliable data goes back 800,000 years through ice core samples.

As far as misleading, I was commenting on the "local" temperature and CO2 graphs to extrapolate the global relationship......that's misleading at best.

Then show me where an ice age occurred when the CO2 was above 400 ppm. There's been many experiments conducted that directly correlates CO2 and temperatures....

Less than two weeks after notching up a record 97.6% of instantaneous renewables on its grid, California has passed a major new milestone, with 100% of the state’s electricity supplied by renewable sources for a short period over the weekend.

According to the California Independent System Operator, the milestone was achieved within a 15 minute period between 2.45pm and 3pm on Saturday April 30, California time, marking the first time ever the massive state has been powered entirely by renewables.

Such levels have become common in smaller grids such as South Australia, but the milestone in California – one of the world’s biggest economies and biggest grids – is hugely significant.
the vast majority of the renewable energy supply was coming from California’s solar power resources, around 12.4GW, while another 4.7GW was being supplied by wind power. Geothermal, small hydro, biogas and biomass filled out the remainder.

well well , california ran on 100 percent renewables with solar supplying the most and lil ol hydro way down at the bottom. i predicted on this forum that cali would one day run on mostly solar and i was just proven right [icon_lol2.gif]

Canadian press which leans way right has now admited climate change is real and has been real all along . https://www.castanet.net/news/Canada/36 ... tudy-shows

Why bother treating anyone's cancer when the treatment causes climate change. Hospitals and health care generate 8.6% of the CO2 emissions. This is how ridiculous people are thinking today.

I think it's more of a self-awareness that the medical system has it's own emissions and that they're looking at ways to mitigate/reduce them. I don't have a problem with that. They're just musing about ways to do something about it. It's not like they want to take us back to the middle ages of medical practice. Or deny people medical attention saying uh no we can't help you...ghg emissions don't ya know. Not gonna happen. Why shouldn't all industries look at ways to reduce emissions?

If the industry is self-aware and wants to save energy, they can also keep it to themselves, especially the climate hyperbole. We don't need medical journals filling with politically slanted narration. Teenagers are already committing suicide, the last thing we need are those in need of medical attention feeling too guilty to receive it. That is about all the opinion article will accomplish in response to Biden's Green New Deal.

Yes, all industries can aim to be more efficient. It is and always has been the natural progression of technology. Is there a rush to accomplish this in 10 years lest we all perish? No.

Some slightly different terminology. There's efficiencies and there's emissions. I think that report was about emissions. Some would say there is a rush and that we may hit a tipping point of no return if mitigation isn't done sooner. Emissions.

Over the last 1000 years, we've moved from peat, to wood, to coal, to oil, to gas, to nuclear, denser and cleaner forms of energy, and efficiency also saves energy. Certain types of fuel create less particulate. Everything is improving over time including building structures and heating/warming efficiencies. Improvements in technology reduce emissions. What-else will hospitals do aside from cut services? There is no tipping point. 1.5c, 2.0c, various RCP models are all guesses and wrong as seen in climate models which all run hotter than observations.

There was a lone doctor recently who wanted to list someone's cause of death as climate change. Extreme idiotic hyperbole does not help anyone.

Any time a new hospital is built, it will likely be more efficient, using less energy then previous hospitals. Such articles are complete tripe and generally out of the hands of doctors anyways.

Don't let these doctors touch me.

Patient: Doctor, please help.
Doctor: I would, but can you imagine the future my children WILL have because you want help?
