There is no simple answer to that
You were asked, "Who created diseases and disasters, earthquakes, volcanoes, floods, famines, tsunamis, tornadoes, typhoons, forest fires, etc. " The correct answer is very simple: nobody. Also, all incorrect answers are simple, too. Name anybody you like and you'll have a simple, incorrect answer.
I notice that you also tried to deflect with, "do we not at least share in the responsibility for undesirable climate-change?" That's irrelevant to the question asked, but its consistent with the Abrahamic tendency to give all credit for good things to its god and all blame for the bad to man and occasionally Satan. You knew you couldn't blame man for natural disasters, but you also wouldn't blame your god, so you equivocated ("no simple answer") then deflected to climate change.
Evaluate .. ponder on .. try to comprehend .. try to live them .. try to gain in wisdom...but not downright reject, or criticize without full knowledge.
"Downright reject, or criticize without full knowledge"? Be honest. Your god can do no wrong in your eyes. You embrace it all uncritically and try to make excuses for what appear to be the sins of this god.
I am willing and able to give God a hard pass on anything I in my mortal condition have any questions about.
This is a more honest appraisal of the believer's approach to his god - a hard pass.
It's all so much more sensible if one drops the deity out of the equation. There is nobody to praise for the good things in life not done by people and nobody to blame for the bad things that happen that we aren't the cause of. We praise nature. We experience gratitude without an agent to be grateful to. It's the authentic spiritual experience, which we recognize as a sense of connection, of belonging, of mystery, gratitude and awe which we experience in a multitude of situations ranging from stargazing to gardening to listening to inspirational music to witnessing a sunset to loving a pet. This is how we evolved.
Contrast that with the Abrahamic understanding of spirituality, which is worshiping spirits that aren't a part of nature at all and redirecting all of that awe and wonder outside of the universe to nonexistent entities in nonexistent places, and when one has a spiritual experience as I described, one interprets it as the Holy Ghost doing this to and for him rather than his own mind experiencing his own world.
These religions go even further destroying the connection to our world that characterizes authentic spirituality. The describe the world in the most negative of terms. Matter (the universe) is inferior to spirit (the other world). The world is an ugly place, bad and getting worse, fit for apocalyptic destruction, a place one shouldn't be involved in, a place where what is called wisdom there is foolishness. The flesh demeans us.
And the result? How many such people tell us that life has no meaning if there is no god or afterlife? What are they telling us has become of them under this training and instruction? All good has been shifted out of reality and is redirected elsewhere. Connection to Mother Nature has been destroyed and they are now connected to nothing and feel alienated in their own world and lives.
