Apparently Earth's C02 levels crossed the 400 parts per million threshold

Carbon dioxide — the gas scientists say is most responsible for global warming — reached a significant symbolic milestone in our atmosphere this month, the Scripps Institution of Oceanography said.
For the first time, daily and weekly values of carbon dioxide in our planet's atmosphere have remained above 400 parts per million, said Scripps scientist Ralph Keeling, keeper of his father's famed "Keeling Curve," the longest continuous record of atmospheric carbon dioxide on Earth.
Ralph Keeling and his late father Charles David Keeling have kept CO2 measurements at the Mauna Loa Observatory in Hawaii since 1958.
"We won’t be seeing a monthly value below 400 ppm this year — or ever again for the indefinite future," Keeling wrote in a recent blog post.
The increase in gases such as carbon dioxide, methane and nitrous oxide is fueling climate change and making "the planet more dangerous and inhospitable for future generations," the World Meteorological Organization has said.
Increasing amounts of carbon dioxide and other gases are enhancing the planet's natural "greenhouse effect."
Based on paleoclimatic evidence, the last time carbon dioxide reached 400 ppm was millions of years ago, according to the journal Nature Geoscience. A 2009 report in the journal found evidence of CO2 levels of 365 ppm to 415 ppm roughly 4.5 million years ago.

What's it supposed to be?

I guess that means happy plants... and happy plants mean more plants... and more plants mean less CO2 and more O2...
I'm cool with it

I am just so sick of science and its agenda.

I was just outside. Didn't notice a difference.

The dinosaurs were driving SUVs?

Was the world habitable then? Was it 400 ppm because of cars, factories and air conditioners? What was done to get those levels down? What caused them to rise there in the first place?

I believe from levels below the surface in arctic ice samples.

Carbon dating. I don't know why global warming is such a political issue. It's happening. There's no denying average temps are going up across the world. The problem is that it's natural for our planet to go through warming periods, as clearly this is not the first time this has happened. Human's are not causing global warming, but we are speeding it up. Why conservatives deny that I do not know. On the other hand, liberals act as if we "go green" we can stop global warming. Well, that's wrong too as, again, it's only natural for the world to go through periods of warming. The only thing humans have to do with is how fast it happens. I'm sure when the next ice occurs half the population will say it's not any colder and the other half will say it's all our fault.

Global warming is fake.

It's all relative.

This thread is proof the average poster is retarded on this site.

I'd suggest testing in a spot that's not right next to China and India

This happened like 2 years ago
