The bigger threat to most humans is bacteria.
Climate change in the short to mid term affects global infrastructure and availability of resources that people need to survive, the lack of which, especially in the regions most vulnerable to it, is going to cause a huge amount of people to die.
Bacteria in the short to mid term has almost the same effect, being very lethal to people without the means to receive sufficient resources and medical care to survive infection. Antibiotics are an individual part of a complicated medical support system for those types of illnesses, and the lack of them will especially be problematic for the things we are currently overusing antibiotics for. A lot of people (and animals) will die, with a similar end result to climate change, but plenty of people with access to modern medicine and good overall care will be fine, even with a rise of infection rate.
In the long term, bacteria are just a part of a natural ecosystem, and unless we continue to accelerate the evolution of bacteria into a more lethal state (which would have to be more than just the antibiotics problem), while a lot of people will die, there will still be a lot of humans left, and it will probably be the ones with better immune systems. Literally just natural selection.
In the long term, climate change could potentially render the planet uninhabitable (for humans) if an unbridled runaway reaction from general desertification, loss of plant life, and subsequent alterations to atmospheric conditions isn't met with the necessary technology to counteract their more problematic effects.
Together, this means that bacteria will kill a lot of people who are also the most affected by climate change - poor countries with population issues and lacking infrastructure - but in the long term, climate change is an actual existential threat, while bacteria is not.
