Climate Change

Increasing temperature

-

Leading to Climate change

 sea level (melting of ice and thermal expansion of water)

 coastal erosion

 habitat loss e.g. marshes, dunes, mangroves and coral reefs.

 salinisation (more salty) of estuaries, coastal rivers and soils

 temperature freshwaters

 species distribution including local extinction

 pattern of succession due to temperature and this will favour some species more than others.

 rainfall pattern e.g.intensity and frequency (climate change)storms

 distribution of grasslands and savannahs and drying out of wetlands

Northern migration of boreal (evergreen/coniferous) forest

 Forest productivity

Desiccation (drying out), causing wilting, defoliation and — fires.

water or temperature stress to animals

 resistance to opportunistic pests/disease e.g. coral reef organisms

in pests and disease

Pests and disease will move to new geographical areas e.g. spread of malaria

glacial melting at poles

Dramatic in food webs

 productivity and biodiversity e.g. penguin populations
