Quantitatively, the jury is still out. Qualitatively, the verdict is in -- we're causing some of it. When the article talks about "models", one of the main things being modeled is the effect of increasing atmospheric CO2 and other greenhouse gases.
Even if we are partly to blame, and I don't buy into that, history shows nature balances itself out.
If we get to hot, nature WILL cool us off, one way or another, even if it means going into a new ice age.
That is perhaps in the process already......the salinity levels in the northern Atlantic are rapidly dropping.
One thing that's being ignored is the effect of environmental "improvements". An article from a year or so ago admitted that cleanups of soot and other particulates had caused some of the warming.
Since CO2 was going up during the decades when the climate was cooling (up till 1970). And those years had no environmental cleanup efforts, a cursory glance might indicate that it's the environmental rule compliance since 1970 that's "caused" the recent warming.
