No one disputes that the earth is warming. It has been since the last ice age.
What is disputed is whether it's being driven by human activities, and what, if anything, we can or should do about it.
You got most of it right. I have one minor correction.
We have been in an interglacial period of relatively stable climate for about 10,000 years. We had some "minor" fluctuations such as the "Little Ice Age, but nothing dramatic.
Before that there were a series of ice ages alternating with calmer interglacial climate periods.
Since we have been in this interglacial period for a long period of time, a handful of climatologists speculated on the possibility of a new ice age in the 70's by looking at climate trends - hence the stupid claims by deniers that climatologists don't know what they are talking about. Science requires peer review and supporting experiments , and it quickly became apparent they were mistaken.
The VAST majority of researchers did not hold this view to begin with, and in fact a small group was predicting "global warming" due to buildup of carbon dioxide levels as early as the mid-50's.
Dramatic and possibly irreversible changes in climate are occurring right now, and the change in carbon dioxide levels correlates well with those changes. The overwhelming majority of scientific research projects have statistically support the importance of this interaction
The vast majority of changes predicted by scientists as consequences of this phenomenon are occurring - and in fact are occurring far more rapidly than scientists had predicted - not surprising because science is by nature conservative in its predictions due to the fact that every hypothesis is subject to extensive peer review and confirmation experimentation.
I can't imagine any of the deniers have read this far, as they are not interested in facts, but would rather go with their "gut"
It is likely we passed the "tipping" point during the first decade of the century, so it is going to be extremely difficult to deal with so many negative consequences - rising sea levels, more intense weather events, and mass extinctions. For instance, once you replace the reflective power of ice with the absorbing power of darker water, it just accelerates the trends. It is similar with the melting of permafrost releasing significant amounts of even more powerful greenhouse gases into the air.
Knowing the make-up of this board, the deniers are going to quickly be throwing stones my way. Sad that your children and grandchildren will look back and wonder why.
