A similar rise would mean the contamination of aquifers, the recession of coasts and wetlands, up to 15% of the fertile land of Egypt and 14% of Bangladesh would be flooded by rising maximum. Possibly affecting the stability of tropical forests and biodiversity, due to its high degree of vulnerability to environmental changes in the balance, being replaced by degenerated ecosystems.

Coral reefs contain the greatest genetic diversity after tropical forests, including one third of all fish species known. Most are on average water temperatures approach the maximum tolerable without submitting changes in its symbiotic balance.

If the sea temperature rises by 2 0 3 ° C, the stability of some corals would be threatened. Projected increases in sea level also affect their ability to survive, because the stability of coral reefs is associated with the maintenance of a certain distance from the water surface.

The expected warming far exceeds the capacity of migration of natural communities, resulting in destruction without replacement and impoverishment of ecosystems, species loss and ultimately loss of the earth’s capacity to support life. Perhaps industrialized agriculture to respond to the new situation quickly enough (although in the U.S. heat wave of 1988 represented a 30% decline in the harvest of grain), but agriculture in developing countries has no means an such adaptation.

There are many powerful phenomena whose evolution climate change is uncertain, for example, the consequences of an ice-free Arctic Ocean sea currents and their influence on the fishery, or the likely movement of tropical diseases to other parts of the Earth.

Examples such as malaria and dengue fever could spread over a greater proportion of land area, affecting millions of people who are now outside their areas of influence.

The Zapatero government continues with the double talk, speaks to combat climate change on one side and the other slowed down the deployment of photovoltaics and now hampers the thermal, technology to produce electricity from solar heat.

Via Decree dated 5 May has changed the conditions for the installation of renewable energies such as solar thermal, power prices that will compete soon in generation with conventional sources even without taking into account the externalidads such as emissions of CO2.

The industry planned to invest in Andalusia 3000 million euros. and is in tune with the so-called “green dial” proposed as an alternative to the crisis developing renewable energy and green job creation.

In 2007 renewable energy in Spain provided 89,000 direct jobs and an equal amount in inditrectos jobs

Simultaneously warn that failure to put in place emergency measures to eliminate deep emissions have ensured the rise of 4 º C mean temperature.

The British Met Office has recently developed an interactive map following the latest published research and peer tested by the Met Office cisntificos’s own and other renowned scientists. This map reflects the changes that the rise in average temperature of 4 º C would result in different territories and ecosystems, and believes that these changes can take place about 2060 or 2070.

The map is also available in Castilian and in pdf format and want to be a tool to bring urgent relief agreements and deep in the Copenhagen meeting in December, bringing together scientists, governments and NGOs in 162 countries in meeting of the Parties Convention on Climate Change UN COP15, to replace the existing and expiring Kyoto Protocol.
