Many global warming deniers love to hear anything that could imply that there's no such thing as global warming. The latest example that could be used to their defense is Argentina's Perito Moreno glacier that doesn't follow global warming trend, and is constantly growing. Scientists cannot explain why Perito Moreno is showing completely different pattern than most of other glaciers, but on the other hand nobody has ever said how all glaciers should react exactly the same to climate change.
Does this example really show that there's no global warming and climate change? Very unlikely because this is really an exception and not a general rule, and you can find much more places on our planet where glaciers are melting than the ones where they are actually expanding. Arctic, large parts of Antarctica, Himalayan glaciers and many other examples show that there is indeed a rise in global temperature, and that this example with Perito Moreno is really some strange exception that still awaits scientific explanation.
We mustn't forget that climate change is global phenomenon, and that we need to look at things at global level, and if we indeed take a global look we can sadly see that global warming is already a reality. Climate change is not all about ice melting but also about extreme weather events like flooding and droughts that have recently become much more frequent than they used to be. I would really love that science is wrong in this case and that there's no such thing as global warming and climate change bud sadly much more evidences can be gathered to support global warming theory than to deny it.
All current climate change models predict that worse is yet to follow, and that we could see so much more of climate change by the end of this century. Glaciers melting will not only cause significant sea level rise but also water scarcity in many corners of the world. We can still escape the worst if world agrees new climate deal and reduce greenhouse gas emissions, at least this is what science suggest us.
I really do not see a reason why science would lie in this case. What good would science have by making up such a story? Therefore I do not understand people that deny climate change. What proofs do they offer? For one their proof that global warming doesn't exist there is at least ten proofs that climate change is really happening. Call me pragmatic or whatever but to me numbers are the ones that count the most. And numbers definitely support global warming theory.
In any case take a look at this nice video. It will give you much more insight into Perito Moreno glacier, one of the few glaciers that isn't feeling the "global warming heat". At least not yet.
