The rate at which Greenland’s ice is currently melting may mean what we are beyond the point of no return when it comes to global warming.
Despite there being so much evidence for global warming very much being a real thing that is happening all around us, there are still those that deny it is happening. Most worryingly, people in power denying that global warming is an issue. Let’s not dwell on that, though. Let’s dwell on the new and extremely worrying evidence that the ice caps are melting at an alarming rate.
Global warming and the melting of the ice caps is not news. However, reports that we may have reached a “tipping point” in terms of melting ice and rising sea levels is. Even though large chunks of humanity are doing all that they can to counteract it, recent evidence from Greenland, or more specifically its ice, suggest that things are only getting worse.
What has prompted some scientists to make this claim is a period during 2013 where the rate at which ice melting in Greenland actually slowed down significantly, reports the New York Times. A weather phenomenon referred to as the North Atlantic Oscillation is responsible for hitting Greenland’s west coast with warm air. However, when that cycle shifted from a negative to a positive phase it naturally slowed down the rate at which ice was melting.
This all sounds like good news, right? Unfortunately, not so much. The cycle switching from positive to negative isn’t a new phenomenon. In the past, the switch has been so minimal that there was a negligible difference in the rate at which the ice was melting no matter what phase it was in. The fact that it changing now has a drastic effect on how much ice does or doesn’t melt is a surefire sign that global warming is getting worse.
The good news is that some scientists believe labeling it a “tipping point” is not okay. Not only do they think that is a wrong assumption to make, but it also might stop people from trying to instigate change. If the damage is done and cannot be reversed, then why bother trying? It’s a good point, and news that living sustainably is potentially having zero effect on stopping global warming may result in things becoming much worse.
