How's that a bad thing? Why are you so concerned about others not having kids?I read the articles - all are in the context of locations with increased rainfall. I completely agree that in those areas, mosquito vectored diseases will spread. Mosquito born diseases are also spreading due to evolutionary adaptations in the mosquitos themselves. In areas projected to have increased temperatures with decreased rainfall, we will not see an increase in mosquito vector diseases.
With respect to the rate. Are you suggesting that the current rate of carbon addition by humans will continue without restriction (even without carbon taxes on peanutbutter sandwiches)? Of course it will not.
As populations industrialize, inflection points occur with birth rates and the need for the dirtiest energy producing fuels. During this time progression efficiency and cleaner energy technologies will develop, and replace older dirtier technologies. The atmosphere is going to get a whole lot more CO2 until central and south america, africa, india, and asia indulstrialize. That process will not be stopped. The rate will increase, but it is going to inflect.
If you extend your logic about not having children because of the terrible awful world we will leave them, then I suppose no one should have reproduced during the dark ages when things were actually bad, or the younger dryas when we had ridiculous mega fauna and human die offs. Irrespective of the current environmental circumstances, organisms that care about their line do reproduce.
And yeah - there are nutjobs that are going childless in the US to reduce their carbon footprint. I guess that's a good thing, because they will wipe themselves out.
