Global Warming

The consequences of global warming include:

Ice

Ice

  • Melting ice causes sea levels to rise, which could flood coastal habitats forever, losing the land and associated biodiversity.
  • Changes to the way sea ice changes through the year is affecting the survival of animals at both poles.
Extreme meteorological events

Extreme meteorological events

  • Extreme meteorological events, such as floods, droughts, severe storms and wildfires are happening more often.
Sea surface temperatures

Sea surface temperatures

  • Rising sea surface temperatures are causing bleaching of sensitive corals.
Ocean acidification

Ocean acidification

  • Increased acidification (becoming more acidic) of the oceans is making it harder for corals to build their skeletons.
Migration patterns

Migration patterns

  • Many migration patterns are likely to be altered by global warming.
Distribution of species

Distribution of species

  • Malaria-carrying mosquitoes have already spread to several European countries.
  • It is possible that malaria and similar exotic diseases will become an established part of life as far North as the UK in the near future.
Reduction of biodiversity

Reduction of biodiversity

  • The rate at which the climate is changing makes rapid adaptation key to avoiding extinction.
  • This is particularly challenging for large-bodied animals that typically have longer generation times.
