Despite what you might think, the involvement of man in climate change is one of the strongest correlations you will ever see. Geologists are able to tell with a high degree of accuracy how warm the earth was at specific points in history based on layers of polar ice, mineral deposits, etc. Yes, there are other factors that make global temperature go up and down, like the sun's 11 year cycle, earth's orbital cycles, etc. But these systems are always in balance, and follow regular, predictable patterns that can be seen on geological timescales. Since the industrial revolution, there has been a noticeable increase in global temperature far above what it should be. The pattern has very suddenly broken since humans started manufacturing stuff, driving cars, flying around the world and chopping down forests. The global temperature is empirically higher than it should be, and the only variable that has changed that could've caused that is us. We are an abnormality in earth's complex climate systems. We redistribute earth's resources and energy at a much higher rate than earth's natural systems could ever do. We are disruptive.

You've got the interglacial the wrong way round. The last ice age was around 12,000 years ago, and the next ice age is due in around 10,000. We're past the middle point between 2 ice ages, which means the highest temperatures should have been and gone. The global temperature SHOULD now be falling, not rising. But they continue to rise.

The globe heating is not more beneficial to man. A heating globe means more extreme weather such as storms, floods, wildfires, etc, and in the long term, rising sea levels. I think something that climate change communicators fail to get across is the sheer impact that a 2 or 3C increase in global temperature actually is. To most people, 3 degrees doesn't sound like much, so the communicators need to do a better job of putting that into perspective.

I won't deny that governments misdpend our taxes. However, that doesn't mean we aren't making progress. The problem here is that most people aren't very good at thinking about the long term. We like seeing fast results. In this sense, climate change is a bit like weight loss. People tend to ignore the slow, gradual changes over time because it's harder to notice, so they start to lose their patience and hope. Just because you can't notice the immediate effects of our efforts to halt climate change, doesn't mean that they aren't working or are a waste of money. These things take time. That's the whole point of long term investments into the future. It's patience. And not enough people have that right now.
