English Committee Chairman of the Scientific Committee on Antarctic Research (SCAR), Jerome Lee, has said in the XI International Seminar on Environmental Journalism Cordoba, the average temperature of Earth will rise during this century of 1 to 6 degrees Celsius.
This increase could lead to complications for living species, as the safety limit of the increase in global mean temperature is set at 2 degrees Celsius by the European Commission (PDF) -limit is designed to limit probability of occurrence of massive and irreversible changes in the global ecosystem.
Iberian Peninsula could exceed the safe temperature which includes the CE López explained that increased temperatures can lead to "complications of survival", since among other things, can alter the migration of animal species.
however, has clarified that warming trends are not equal in all areas of the planet. While in some areas the average temperature has risen half a degree, in the Iberian Peninsula has been an increase of up to three degrees in recent decades. To continue, the Iberian Peninsula, according to estimates exceed the number of security-which includes the EC for this century.
Algae produce oxygen
For his part, Professor of Biology Ulf Karsten, who researches the effects of climate change on the University Rostock, has warned that global warming is causing the extinction of numerous species of marine algae, which have an adverse effect on the volume of Earth's oxygen.
Seaweed is the real green lung of the Earth
Karsten explained that algae in the Arctic regions are very sensitive to temperature changes and said that the countries most affected by his disappearance are Sweden, Norway and Britain.
also noted that the extinction of these marine plants involves the decrease in oxygen level as the planet through its photosynthesis process generated 25% of the total of the gas in the earth. "Seaweed, living up to 260 meters deep, are the real green lung of the Earth," he said.
