"No, we haven't reached a climate "point of no return."
That's the overwhelming message from climate scientists in response to an alarming climate study that many experts described as flawed when it splashed across social media last week.
Yes, there's still hope to prevent catastrophic global warming. And yes, reducing greenhouse gas emissions to zero could still halt climate change, they said.
Published in the journal Scientific Reports, the paper suggests the world has crossed an irreversible climate threshold. Even if all greenhouse gas emissions were stopped tomorrow, it concludes, the world would continue warming for hundreds of years. Indeed, the authors said that emissions would have had to stop in the 1960s to prevent runaway warming."
