ARKive - Images of Life on Earth

International Day for Biological Diversity - 22nd May

Global biodiversity, already threatened by human-caused habitat loss, pollution and over-exploitation, now faces the additional threat of a rapidly changing climate - a threat which is predicted to become the dominant driver of biodiversity loss by the end of the century.

This loss of biodiversity has major implications not just for the variety of life on our planet, but also for the livelihoods of the many people around the world who are especially vulnerable to the loss of essential ecosystem services. As policymakers from around the world seek ways to help the poorest people to adapt to climate change, priority must be given to the role of biodiversity, an element often neglected from current adaptation strategies.

Moreover, just as biodiversity is greatly threatened by human-induced climate change, it also has the ability to reduce the impact of climate change on the planet - forests can reduce the amount of carbon dioxide in the atmosphere and mangroves and coral reefs can lessen the impact of climatic extremes on coastal regions.

Given the inextricable link between biodiversity and climate change, conservation of the world's biodiversity is now more important than ever.

Biodiversity and Climate Change

Primrose plant in flower
Early blooms
Flowering is especially sensitive to temperature - average first flowering date of many British species has advanced in the past decade.    See more
Male polar bear
Precarious place for polar bear
Climate change is having a profound effect on polar bears, their sea-ice habitat and the seals on which they prey.    See more
Male golden toad
1st attributed extinction
One of the first known casualties of global warming, the golden toad has not been seen since 1989 and is now classified as Extinct.    See more
Tuamotu sandpiper
Hazardous sea-level rises
Concern has been expressed about the impact of sea-level rises on the small islands on which the Tuamotu sandpiper breeds.    See more
Female green-eyed skimmer
Increasing droughts
Water pollution and stream-drying due to increasing summer droughts pose potential threats to the survival of this species.    See more
Giant South American turtle hatching
Fewer males in warmer times
Sex determination of the mugger depends on incubation temperature: a rise of a few degrees could eliminate males altogether.    See more
Blue tit
Birds out of synch with food
Breeding success of the blue tit is being affected by the changing availability of its caterpillar food, which now appears earlier in the year.    See more
Sperm whale swimming at surface
Warmer seas, fewer calves
Sperm whales have lower breeding success during warm water El Nino events, which are becoming more and more frequent.    See more
Female leatherback turtle preparing nest
Loss of breeding beaches
A sea-level rise of 50 cm could result in a 32% loss of turtle nesting beaches within the Caribbean.    See more
Comma butterfly on flower
On the move
The increase in abundance and northerly range expansion of the comma butterfly in the UK are both in response to a warming climate.    See more
Salvin's albatross in flight, dorsal view
Less fish for albatrosses
Gradual ocean warming as a result of climate change could be a potential threat, through impacting food availability, for all albatrosses.    See more
Macaroni penguin moving through soft ice
Sensitive penguins
Penguins are extremely sensitive to changes in sea temperature and ocean currents and the consequent decrease in prey availability.    See more
