Carbon dioxide levels in the atmosphere hit record high

NOAA says carbon dioxide levels hit a record high last month, a troubling development for the future of the climate. CBS News weather producer David Parkinson joins CBSN to explain the significance.

Yes, and 3 million years ago, CO2 levels were even higher. And then along came an Ice Age.

Is it not true that historically CO2 levels are at a low point, how do you work out they are at a high ? What would happen if they went down
to 150 ppm ask any botanist, we are helping the Earth by putting a small amount of CO2 back in to the atmosphere.

[repeat]

Nope they are not on record levels. In the late Ordovician it was over 5000 ppm.

Increase in cars and factories and emissions yet you are supposed to get a clean supply of air in our cities and towns

Why cry make electric cars trucks more affordable

In Earth’s early history, global temperatures were very high for a very long time despite the sun being dimmer than it is today. This was due to the ‘greenhouse effect’ being strengthened by very high levels of methane and carbon dioxide in the atmosphere. At this time, no oxygen existed in the atmosphere and only simple anaerobic life forms existed; but Cyanobacteria evolved and photosynthesis began releasing oxygen which breaks down methane (30x more potent than CO2) into carbon dioxide. The weathering of fresh basaltic surfaces from tectonic plate rifting then drastically reduced the amount of carbon dioxide in the atmosphere. Eventually, methane and carbon dioxide levels were reduced to such low levels that the Earth’s surface was frozen solid for over a hundred million years.

Hothouse Earth — Then about 250 million years ago, a “large igneous province” (LIP) in Siberia erupted huge and greatly prolonged volcanic basaltic flows for over two million years and dumped so much CO2 into the biosphere that the oceans acidified and atmospheric temperatures soared causing an extinction event called The Great Dying. Other LIPs occurred later causing CO2 levels and temperatures to again spike and, thus, induce other extinction level events.

Our kids are going to be proud of us..

It doesn't need to it's already at saturation

[bradgrauer]

I'm an actual meteorologist climate scientist what this guy is saying is a crock higher CO2 levels are going to stop mainly because you're going to have a lot ofGreening plant growth and crop growth CO2 has not been or ever been a pollutant gas

[lilepopinyou]

The earth will find a way to remove us all And I will let it

[timberrr]

See “Quantino car” It runs on salt water. No CO2.

Very good you report this iT, S Said but the Truth .

[joshuarowe]

The amount of Carbon dioxide in the air is at the low end of where plants thrive. Better plant life means cleaner and better air, more food production, and is a good thing.

🤔Ummmm dumb!🤤Disregard the volcano that just went off there! I bet the carbon levels are a bit High!😐 I'm willing to bet every level is a little high!😉😁

Jes sayin, they have been much higher many times throughout history per ice core samples. Just a comment cuz I don’t have strong feelings about much of anything.
