I'm a physician and I do not think humans are causing climate change. I do not have an agenda or bias. I just don't think the limited data we have rules out the much more plausible cause which is natural cycling of the weather.

For one thing humans don't cause climate change. The world has been in a warming trend since 20,000 years ago when Chicago was under 3 miles of ice. The argument is over whether humans affect climate change and if so to what degree. It's pretty obvious that the world is warming faster than it would absent any human activity. There is scientific theory that predicts this and scientific evidence that verifies it. It's less obvious whether the way in which human activity affects climate change is significantly harmful to human life.

Can you point to any specific theories that better explain the existing weather data?

There are people who spend a lot of time going over the data, and the overwhelming consensus (97%) among them is that we're causing it, or at the very least, making it worse. We're definitely causing it. And there is evidence showing that earth is warmer than it's been in the past 2000 years. Reports from the IPCC state that the second half of the 20th century has a >90% chance of being the warmest 50 year period in the last 500 years and a >66% chance of being the warmest in the last 1300 years. It's not a coincidence that this is also when we started pumping carbon dioxide into the air - CO2 levels and global temperatures are very closely linked. There is evidence of climate change raising sea levels (r=.99) in addition to many other harmful effects, which are laid out in detail by the IPCC. Also in that last link is what we can do about it.
Climate change is real, dangerous, and not up for debate anymore.
