Of course, projections aside, there's little observational evidence that extremes are increasing, despite the rise in greenhouse gases. It is pretty obvious that fewer people are dying because of weather. Air pollution is a trickier problem, since it is only indirectly related to climate change. Most greenhouse gases are not pollutants, so we are left with theoretical arguments such as higher temperatures' increasing the reaction rates of certain pollutants. Furthermore, it's not possible to determine the impact of air pollution on health without first accounting for the weather.
Some studies even indicate that weather is far more responsible for deaths than pollution.
The spread of disease. So it is unfair to insinuate that more drinking water will be flooded and thus contaminated. Despite the multiple millions governments annually pour into global climate models, their output provides zero useful guidance on what the future climate will be like. So we are left to rely on history to anticipate the future. The last time we checked, the climate was the same in both places.
