Daily measurements of CO2 at a US government agency lab on Hawaii have topped 400 parts per million for the first time.
The station, which sits on the Mauna Loa volcano, feeds its numbers into a continuous record of the concentration of the gas stretching back to 1958.
The last time CO2 was regularly above 400ppm was 3-5 Million years ago - before modern humans existed.
Scientists say the climate back then was also considerably warmer than it is today.
Carbon dioxide is regarded as the most important of the manmade greenhouse gases blamed for raising the temperature on the planet over recent decades.
Human sources come principally from the burning of fossil fuels such as coal, oil and gas."..."
What exactly is this 400 PPM level symbolic of ?

global climate change.
it's been millions of years since CO2 levels have been this high.
But its not been millions of years since temperatures were higher . Indeed they were higher for most of the last 12000 years than those we see today minus capitalism

Heres a shattering though for you . What if its natural ?
LOL.
I thought you said that data was wrong, and you burned thru many posts to pretend you showed it.
No its was just (as ever) your lack of comprehension
How much data would you like that shows the same ? (Kobashi 2011 4000 year ice core record). I'm wondering you have the intellect to comprehend graphs and what they mean but I'm really not that hopeful
You are pulling out a single ice core record again while simultaneously ignoring all the other ice cores and other temperature proxies?
Seems like you could do gainful employment to make extra money instead of lying about how the evil scientists are gonna steal your pension someday

Given that is demonstrably the case heres a shattering thought for you . What if its natural and niether we nor our demonic CO 2 have anything to do with it ?
What will you do then ?
They are suggesting we change our lives because of a symbol.
You're right it is symbolic. Purely.
Meanwhile, here in the Real World, we are still not getting warmer, but people are still getting hysterical.
The concentration of CO2 on top of an active volcano is alarming? I bet the concentration is much lower in the Mariana's Trench.
Can anyone tell me how long I have to wait before my house is beachfront property? I live in Ohio and am trying to evaluate my options for retirement planning.

I was afraid that would be the answer. Warmists are like politicians. All they do is make empty promises.
global climate change.

I'm pretty sure the explanation was on the first post.
But I'm starting to see your comprehension problem. You only read thread topic subject lines, not entire posts.
That explains a lot.
