There is no serious doubt or debate: anthropogenic (human-effected) activities are driving more hurricanes than ever, more intense killer heat waves than ever in recorded meteorological history, more rising seas, more forest fires, more flooding and more salt water encroachment into formerly pristine, potable groundwater along coastlines.
The debate that annoys me most, to be frank, is the “It doesn’t matter what I do, since the huge consumers of fossil fuel are what matters,” or “My personal sacrifices, like taking cold showers and sweltering without air conditioning, are so unimportant and so miserable that just forget it.”
