Many different experiments and studies have been conducted at all these levels and these studies have received thorough reviews by other scientists and panels of prominent scientists. Thus our ideas about climate change do not rely on the work of a few researchers, but many different researchers and a thorough review process. Thus the evidence is quite strong.
4. Even with all this evidence, many scientists would not say that climate change has been proven. However, there is so much evidence for human caused climate change, many scientists think it is extremely likely to be occurring. If it is occurring, and we do nothing, society will suffer greatly. If it is not occurring, and we work hard at trying to prevent it anyway, then maybe we have wasted some effort, but society will not suffer like it will if climate change is real.

I
have written that all of science is only an opinion. I then hasten to add
that scientific opinions (theories) can transition to something the textbooks
call Laws, but only when they have been tested time and time again and in
many different ways and in every single case have been shown to be true,
accurate, and precise. Once a scientific theory becomes a Law, this only
means that the scientists who have tested them have such strong beliefs, or
opinions, in their correctness that they would be willing to stake their lives
on them.
Collectively,
we cross bridges and fly in airplanes because we believe completely in the laws
of physics that support airplanes in flight and bridges that do not fail. We
know that occasionally an airplane will crash and a bridge will collapse, but
we understand that this is not due to any failures in the laws of science upon
which the designs of the airplane or bridge are based, but upon human failure
and material failures in the parts of the airplane or bridge that were not
detected and corrected by those responsible for such work. So even the critics
of global warming believe in science, to the extent that they are willing to
take their chances with airplanes and bridges. It's just that there is some
science they don't want to be true. So they have trouble accepting it, even
when the evidence for it is both robust and alarming.
