A 1 °C increase in temperature has disrupted the entire ecology of the world’s largest High Arctic lake. The warming has resulted in a 10x increase in glacial meltwaters, sediment, and organic carbon delivered to Lake Hazen.

There's a good argument for you folks to use whenever someone questions the legitimacy of manmade climate change:

Usually they might say something along the lines of: "Manmade climate change is only 5 or so percent of all climate change. Yet it's supposedly going to end the entire world. Makes you think, huh?"

To this, you say:

Let's say you're about to bench press 225 lbs. You've been preparing for this moment for a long time. Then comes your friend and adds 10 lbs to that weight. Instead of getting the bar up from your chest, the weight collapses on your chest and you end up in a hospital.

In the hospital, your friend says: "Dude, I only added 5% of your total max rep to that weight. How did you end up like this?"

See how a small change in something can have very detrimental effect?
