At bioclimate.org you will find a categorised, searchable and filterable listing of media which deals with climate change and biodiversity.
Climate change poses a huge risk for nature, both for biodiversity and the richness of ecosystems. The Intergovernmental Panel on climate change says that it is expected that this situation affects both individual organisms, populations, species distribution, and the functioning of ecosystems due to increase in temperature, changes in patterns of precipitation, extreme weather and increases in the level of the Sea (IPCC, climate change and biodiversity, 2002).
Future scenarios beyond the ability of many species adapt, whether through migration, changes in behavior or genetic modifications, which can result in the reduction of populations, decrease in diversity and even the extinction of a significant number of species that are more sensitive to changes (Smith 1997).
Studies carried out by the World Wide Fund for nature (WWF for its acronym in English) indicate that one-third of the habitats of the planet are at risk and could both disappear or transform by the end of this century.
Those species that found in Islands, mountains and peninsulas, those with small populations and those who have difficulty migrating will be most affected by climate change. It is worth mentioning that current conditions make the migration of species a much more difficult process that thousands of years ago. Today, with a population of more than six billion people and where habitats are fragmented, migrations are a challenge for many species.
There is already evidence of how species are responding to global warming. Some examples include the following:
In Costa Rica the golden toad may have been extinct due to their inability to adapt to the change in temperature
Birds such as the blue chara in Arizona are starting to play before time.
Alpine plants are moving to higher latitudes in Austria
Mammals of the Arctic as polar bears are feeling the ravages of global warming in the decrease of the ice
The surface temperature of the oceans have been a phenomenon that bleaches the coral that deliver a seaweed (which gives the color coral) by high temperatures, alters its production of nutrients
Penguin populations have decreased by 33% in parts of Antarctica
The loss of species may also alter the production of goods such as food, water, wood, etc. and be a threat for all those people who need nature to survive. On the other hand, l to decrease of biodiversity can affect the maintenance of the fertility of the soil, the transport of nutrients, biological pest control, soil formation, erosion control and pollination of plants, notably affecting the ecological balance of the planet.
Mexico is regarded as one of the first five countries with greatest biodiversity, with about 60% of the biological wealth of the planet (INE 2006). Therefore, it is essential to address the issue of climate change and develop actions that help to mitigate it as soon as possible and prevent damage to our natural heritage.
