Here, let me frame some questions for you:
1. Do you believe climate is changing?
2. Do you believe the world is warming?
3. Do you agree climate change is influenced by anthropogenic activity?
4. Do you expect climate change will result in catastrophic consequences to the world and/or humanity?
5. What should we do to limit the negative effects of climate change?
Before I express my opinion, let me tell you about myself. I have 25-30 years experience working in a field of natural science or engineering. I have degrees from three different universities. I have published a number of peer-reviewed papers about natural phenomena in scientific journals. I am not a climate scientist; the closest thing I have written about is permafrost. But I have scientific training and can read the scientific literature critically and filter through the noise on both sides of the discussion. I also have a particular academic interest in chaotic natural processes and the statistics of extreme events.
I've been working pretty hard in my spare time for about the last 5-6 years to try to understand climate generally and climate change in particular. It is a very complex topic...
I'll start by answering the first couple of questions.
1. Yes, climate is obviously changing. I think most people accept this, and have moved on to the more pertinent question, #3.
2. Yes, the world is warming. At least, this is the general trend over much of the last century. I've spent a lot of time looking at temperature data, both at individual sites, and compilations of data. Much has been made of the "pause" since ~ 1998. Some declare this as evidence that "global warming" has ended. Others claim no such pause has occurred, and instead emphasize that this period has been the "warmest ever." Both of these claims are ridiculous; a 16 year trend tells us nothing about precedent or future conditions on the one hand, and the 150 year instrumented record cannot be used to decide "most/least/worst ever" about any aspect of climate.
My answer to #3 is longer and more nuanced, I'll come back to it later.
