> Earth’s atmosphere now has more carbon dioxide in it than it has in millions — and **possibly tens of millions** — of years, according to data released Thursday by the National Oceanic and Atmospheric Administration and scientists at the University of California San Diego.
> For the first time, global average concentrations of carbon dioxide, a greenhouse gas emitted as a byproduct of burning fossil fuels, exceeded 430 parts per million (ppm) in May. The measurements indicate that countries are **not doing enough** to limit greenhouse gas emissions and reverse the steady buildup of C02, which climate scientists point to as the main culprit for global warming.
> “Another year, another record,” Ralph Keeling, a professor of climate sciences, marine chemistry and geochemistry at UC San Diego’s Scripps Institution of Oceanography, said in a statement. “It’s sad.” Atmospheric carbon dioxide has risen sharply since preindustrial times, owing mostly to **human activities that pump greenhouse gases into the air.**
> Human society is already in uncharted territory. The last time the planet had such high levels of carbon dioxide in the atmosphere was likely **more than 30 million years ago**, Keeling said, long before humans roamed Earth and during a time when the climate was vastly different.
Check out this page that shows CO2 levels over the last 800,000 years. Previous to the industrial revolution, levels (as PPM – parts per million) changed by 1 or 2 over hundreds of years. Afterward, the level has been going up by 1 or 2 PPM every year.

Keep thinking back to that moment in Congress back in the 80’s when Carl Sagan warned of us all very clearly.
Since then we’ve gone from under 370/mil to 430/mil. Our grandchildren will curse literally all of us in the future for what we did to their planet, for cheap Chinese goods to make us fleetingly happy.
Same old news, new year. We’re slowly making our own planet uninhabitable and it’s not going to change until the reality of “oh I can’t spend my money if I’m dead” is immediate. If it’s not in our lifetime, who cares, right? We might of made our species extinct, but we made money. WHO cares if we kill billions tomorrow , you can have a yacht today!
It wouldn’t be so bad if people wouldn’t be so ignorant… turning on air conditioning in a hot day, only makes the day hotter for the planet…

All these comments about “we”
Dudes corporate interest and government corruptions bought and sold this world right from under us all! Like I’m working class not flying private planes and bribing people to line my pockets etc
BUT WE HAVE TO SELL AI PANTIES AND SOCKS! COME ON! LET’S USE SOME MORE RESOURCES FOR ANOTHER USELESS THING! OH LOOK, IT’S RAINING ACID. MY SUPERTRILLIONARE ARSE DOESN’T CARE! HEY SIRY, WHAT ARE MY CHANCES OF SURVIVAL IN MY UNDERGROUND BUNKER MADE WITH POOR PEOPLE BY POOR PEOPLE?
