Why is global warming contrary to God's design for creation?
Human-induced global warming is a rejection of Genesis 1:28, which requires man to 'replenish the earth'; an instruction to look after our planet.
True global warming does not decrease temperatures. So, either the model for global warming's effects is hokus-pokus, or global warming as presently claimed, does not exist. Some global warming followers will have you believe that global warming makes the weather "act crazy". If true, then it is not really global warming, is it.
Everything continues to global warming. You breathing, contributes to global warming. Me typing this response contributes to global warming. Toilets contribute to global warming because they are a manufactured product. Anything Manufactured requires energy and materials , all of which contribute in some way, even if minor to global warming.
"Climate Change" and "Global Warming" are not the same, though related. Global Warming causes Climate Change. With Global Warming we understand the warming of the earth's global temperature. That warming has in turn an effect on the earth's global climate and on more localized climates (like the climate of England or Western US).
I do not think that global warming is a myth. There are some who debate the reality of global warming, and others accept that it is happening but deny that humans are substantially responsible for global warming, but these debates simply prove there must be something to it. Global warming is no myth.
