I just think that we are over reacting to the natural occurrence of climate change.
We are overreacting even if it was manmade, which is certainly possible. It was 3 degrees warmer 120,000 years ago.
I'll leave in the middle if it's entirely natural, entirely man-made, or natural with man exacerbating the problem for the sake of this argument below:
Re '120,000 years ago': Keep in mind that at that time we were hunter-gatherers who knew very well what they had to do for food. Presently most people couldn't grow a head of lettuce if their life depended on it, so to speak. The funny thing is that they spent roughly 9% of their time to support themselves.
Amusing anecdote aside, there are presently 7 billion of us versus ~15 million then. A 3 degree average rise in temperatures might not harm us directly, but have you given any thought what it will do to our arable land? There are plants we eat better suited to colder climates that we may have to make do without. What will a 3 degree average rise in temperatures do for the kinds of fish and seafood we eat?
It's easy to dismiss it with the wave of a hand and day, but oh, we survived it 120,000 years ago. We've since grown ~450x more numerous in population, are most of us far removed from nature and literally couldn't survive if it wasn't for the supply chain of the food industry. Population is still growing, projected at 10 billion by 2100.
Does a 3 degree rise in temperature on average not also bring with it a rise in sea levels, further reducing arable land, tsunamis, brush fires, what have you? There are so many things to consider, but the basics of potable water and food is one very things threatened. I'm not saying we should panic, but to dismiss a call to action as an overreaction?
It might be a good suggestion to read up on horticulture and hydroponics, I can certainly see it becoming a favourable set of skills to have. Rock wool might be a nice medium term investment. Desalination technology, likewise.
I'm just saying that it's mighty easy to point to 120,000 years ago with a much smaller population who came by their food in a much different way, then say we're overreacting. Their situation was very different to ours and that 3 degree rise in average temperature is one of few things we have still in common. I wouldn't be so quick to dismiss the concerns based on their survival skills, they at least still had a connection to nature that is foreign to most of us in the developed world.
fix: hunter-gather population estimate

This amount of awesome cannot be from concentrate.
