were this high came during the Pliocene Epoch, which extended from about 5.3 million to 2.6 million years ago. During that period, average sea levels were about 50 feet higher than they are today and forests grew as far north as the Arctic, said Rob Jackson, a professor of earth system science at Stanford University. “Earth was a very different place,” he said. “You would hardly recognize the land surface, and my gosh, we don’t want to go there.
, named for Keeling’s father, Charles David Keeling, who began taking daily measurements of atmospheric carbon dioxide in 1958 from atop the Mauna Loa Observatory in Hawaii. The curve shows a steep climb, owing to human-caused climate change. But it’s hard to say exactly what these changes will bring, or when. Some things, like the loss of vegetation and sea-ice coverage, will grow increasingly visible in the short term. Other things, like theand Greenland, occur more slowly. “But these impacts are going to persist for a very long time,” said Dana Royer, a professor of earth and environmental sciences at Wesleyan University in Middletown, Connecticut. “Once that happens, we can’t really reverse it.
MACH This makes me sad
MACH Amazing! How did they find the records from 3 million years ago?
MACH We need to stop killing ourselves, how about now!
MACH Important Message; Trump has embolden the ignorance, If you did not graduate from High School, you can not post a comment on climate change. You are to stupid to comprehend. For every action there is a reaction. We are losing our planet and habitat. Extinction is Real.
MACH More Globalist study’s to try to Tax the world. More of that Fake News they’ve cooked up.
MACH Question is what caused these carbons 3 million years ago ?
MACH It is hard to believe how many science deniers are on here posting. WOW!
MACH So many morons that don’t understand climate change on this thread. This is why we need to update our education system.
MACH How did they measure this three million years ago?
MACH The most effectice way to tackle climate change? Planting one trillion trees.. Teenager on track to plant one trillion trees to fight carbon dioxide. That's about 150 trees for every person on Earth
MACH Blame it on developed countries
MACH How exactly do we know the carbon dioxide level three million years ago?
MACH For mental health and optimism l try to stay clear of too much pending doom and gloom, however it is apparent that our planet is in great danger from all sides, a total disregard for Mother Earth.The air, the soil, the waters becoming progressively polluted and poisoned by abuse.
MACH What will China and India do to reduch their carbon emissions?
MACH I didnt know we had been keeping records for3 million years please present those documented records
MACH Yawn.
MACH I give you a D- in green journalism. All you do is teach people to complain about the problem and seldom mention the very real efforts underway to provide solutions. I realize your goal is to establish socialist committees to coordinate doing nothing and obstruct progress.
MACH What a crock of shit! Who do you know that was recording the levels three million years ago? How about one million? One thousand? That’s what I thought! Propaganda!
MACH And, we’ll all still be here fifty years from now. Blah, blah, blah.
MACH Can the entire World send America billions and a trillion dollars, so America can save the planet. Because all the money America gave away , like we drank too much, didn’t solve you rich people making big bucks, saying America needs to do more.
MACH Democrats need to stop farting then this would cease to be an issue 🤷🏿♂️

MACH India, China, Far East & Middle East, not doing a dam thing , compared to America, quit crying babying to America, bring your butts over to the countries above &cry to them. don’t come back for at least five years, to make sure all these countries will die, if they don’t change
MACH 3 million years ago? I didn’t realize SUVs have been around that long. What corrected the CO2 levels then, caveman CO2 credits, gas taxes?
MACH Im OK with carbon dioxide..its a gas...
MACH Well... the ones who couldn’t pass or even understand the science class chose politics and now run the country... they didn’t like the science kids anyway...
MACH There is no correlation between CO2 and Climate change but hey we appreciate the Fake News.
MACH
MACH Lets talk about my potential to become 20 years younger and a million dollars richer instead.
MACH harrp
MACH Who was reporting 3 million yrs. ago? NBC?
MACH But trees make oxygen right? And I can only afford dead ones
MACH House is On Fire and Nobody's smellin tha smoke!!!!!!
MACH And today in headlines we’ve never seen before. . .
MACH
MACH Is this headline 1970, 1995, or 2019?
