1. Human: Global warming will impact on all biodiversity including mammals (human). Human health will be affected since there will be proliferation of pests and pathogens in a warming world which will have several consequences, in particular cholera and malaria epidemics are projected to expand in some countries/locations, food poisoning might increase since higher temperatures generally favour the multiplication of harmful bacteria such as Salmonella. There will more environmental refuges due to increase in the frequency and intensity of disasters like cyclone, floods, droughts and storm surges. One of the most serious consequences will be (locations based) sea-level rise impact on assets and infrastructure, food and water (due to salinization) and human health.
2. Other biodiversity: Many species have already shifted their geographical ranges, generally poleward, towards higher elevations, or to deeper depths in marine environments to escape rising temperatures.
As it turns out the extra evaporation of the oceans (due to higher ocean temperatures) has caused a dramatic rise in humidity (instead of higher sea levels).
We have suffered a lot these last 3 years with breathing problems ( I got asthma) due to the increased humidity.
direct impacts on humans relate to heat waves, high humidity, etc.
indirect impacts relate to a number of other hazards that effect people quickly and unexpected such as cyclones, droughts, or slowly sea-level rise, etc.
