One of the most important parts of establishing a stance on an issue is being as critical as possible of evidence that supports your view. Reason being, people tend to throw the baby out with the bathwater and so if you start to give facts and figures that support what you’re saying, if one is proven false, it’s very hard to dig yourself out of that hole.
Today’s tidbit isn’t exactly in that ouvre, but the point is to not that, while it’s true that the massive icebergs floating up in the arctic are going to cause issues for local marine life, the scientists are pointing out that it won’t wreak havoc on the climate system of the planet as a whole.
However, the researchers say the changes to the region triggered by the formation of the new iceberg will not shut-down the circulation system or affect the world’s climate.
“Large icebergs always attract a lot of attention due to their scale,” observed Dr Michael Meredith from the British Antarctic Survey, who was not involved in the research.
“Bottom water is indeed an important part of the global ocean overturning circulation and hence climate,” he told BBC News.
“There are also a number of other locations of bottom water formation, however, so it’s unlikely that a large-scale sustained change of the order of magnitude required for a global climate impact will happen from this one event.”
That said, there is a nugget of concern in there, and that is this: the possibility of certain regions becoming colder as a result of global temperatures rising.
See, this is one of those issues that seems terribly counterintuitive and thus is perfect fodder for criticism and scorn. After all, how can global warming cause colder winters? It’s warming!!! But that’s just how it works. If the poles get colder and huge chunks of ice break off, they start drifting down and cool off the waters in the surrounding areas, which blows in and causes harsher winters. So, keep that in mind next time you’re in a heated, or even civil debate.
But again, this is not a harbinger of the apocalypse.
