direct impacts on HUMAN
more extreme weather occurences: e.g. hurricanes will become 1. more intense (due to the rapid evaporation as global warming makes the earth warmer), 2. greater period, more months (due to the overall temperature of the Earth becoming higher and more months' temperatures reaching threshold needed for hurricanes to form as hurricanes require high temperature), and 3. more areas will also be affected. so humans will suffer: 1. death and injuries, 2. damage costs

changes in precipitation patterns: moist areas will become wetter as warmer air can hold more water vapour ---> increased evaporation ----> precipitation rates will increase. dry areas will become drier as warmer---> hold more water vapour ---> RH decreases, harder to reach 100% saturated air to form clouds and hence rain
so humans will suffer from extreme changes as we prefer middling conditions---> become uncomfortable to live in
if too wet, plants may drown from an excess of water? if it's too dry, flora and fauna will also die from a lack of water/ forced to relocate, leading to overcrowding and easy spreading of diseases that may wipe out entire populations of animals
melting of glaciers and polar ice caps + sea level rise : melting of glaciers during summer leads to sea level rising as more water in sea ---> sea water also rises due to expansion as the world gets warmer. IMPACT: indigenous ppl living in small islands like Fiji face destruction as their island becomes completely underwater; big cities near the sea also at risk of flooding, e.g. Venice; and destruction of arable land (e.g. Bangladesh).
INDIRECT impact on animals: i guess loss of habitat as the ice caps shrink? animals living in the cold parts will have less land to live on, possibly leading to overcrowding....because it becomes hotter, the animals can't adapt to the heat and may die as they are adapted to live in cold environments
increase in vector borne diseases: as temperature goes higher, more conducive environment for mosquitoes to breed, leading to high rates of dengue, Zika, etc. e.g. in bhutan
