Global warming, or climate change is the phenomenon of increasing average ocean temperatures and air, because of the emissions of greenhouse gases. greenhouse (CO2, etc.). The latest IPCC projections are that global surface temperature could increase by an additional 1.1 to 6.4 ° C over the course of the twenty-first century; Even if the emissions stop, the oceans have already stored a lot of calories, carbon sinks are to be restored, and the life of the Carbon dioxide and other greenhouse gases in the atmosphere is long.
Every seccond in Amazonia 1.350 m2 of forest is destroyed by woodcutter Koalas, Australia’s most iconic fluffy marsupial, is likely to become rarer over the next century due to global warming. Koalas have an extremely specialised diet consisting only of eucalyptus leaves. Increasing carbon dioxide levels in the atmosphere are decreasing the nutritional value of leaves, resulting in Koala malnutrition and starvation. Polar bears are in danger because of pollution and global warming. Climate change is making polar bears go hungry. Climate change poses a significant threat to the survival of humans and animals.Increasingly frequent and intense droughts, storms and heat waves, rising sea levels, melting glaciers, and ocean warming are likely to affect species and their habitats.
The deforested is the phenomenom of regression of the surfaces coverd. Deforested areas can evetually tum into deserts. Reduce the importance of rainfall and cause drought. Without their habitat, hundreds of animal species would disappear.
-The Humain deforest deforest to simply have more space for him : have more space for food, farming...-Deforest reduce the importance of rainfall and cause drought.
The oceans are essential to life on Earth:they provide 50% of the oxygen we breathe , thanks to photosynthesis by phytoplankton. Numerous projects have been proposed – and in some cases implemented - throughout the U.S. and world, encompassing a broad range of designs and locations.The oceans are also true "quot , carbon pumps" ; : they absorb about 30% of global CO2 emission , which makes them to the fight against climate change.It is important to protect the oceans!!!
- The botton of the oceans is not the same depth everywhere.-The World Ocean, which supports the majority of the Earth's living species.
-Generates more than 60% of the ecosystem services that enable us to live starting with the production of most of the oxygen we breathe-The world ocen regulates more than 80% of the earth' s climate. It plays a major role in the earth' s temperature
