Global warming is the rise in the average temperature of Earth’s atmosphere and oceans since the late 1 9th century and its projected continuation. Since the early 20th century, Earth’s mean surface temperature has increased by about 0. 8 co (1. 4 OF), with about two-thirds of the increase occurring since 1980.  Warming of the climate system is unequivocal, and scientists are more than 90% certain that it is primarily caused by increasing concentrations f greenhouse gases produced by human activities such as the burning of fossil fuels and deforestation.
These findings are recognized by the national science academies of all major industrialized nations. This documentary talks about what would happen if more grades increase Of atmospheric temperature, said that would happen if the temperature rise of 1 degree to 6 and the reality is that it would be a disaster, we are hurting ourselves, hurting our environment and also to our future generations if we do not care because we have soon, we will not leave anything for them. With 6 degrees over the world would be a disaster but today twentieth century since we already risen 0. Degrees and is expected to 4 degrees in 50 years and this is very alarming because it is our planet we are hurting. There are several scientific research in the documentary showing what would happen if they increased these degrees, are these: 1 degree (We are only half a degree of that) – Disappearing polar ice and land is exposed at the North Pole for the first time in 3 million years. Powerful hurricanes hit South Atlantic coasts. Two grades: The endangered marine life and the polar bear becomes part of the list of endangered animals. Three degrees (No return): Victim of the Amazon heat wave becomes a bare desert, destroying one of the most important ecosystems in the world and are the first hurricane of grade 6, with a new generation of super storms. Four grades: Big cities are submerged and die half the world’s animal species. Five degrees: The collapse of civilization, under these conditions it is almost impossible to survive the unman species, which will move in search of water and less unbearable temperatures.
In my opinion I think we should take better care of our environment and our planet Earth is our home and to continue in the must take care not only see these kinds of documentaries and guilt and a time to act, if not the opposite should act and try to prevent the planet runs out or at least try to take longer then doomsday give a little more time on our planet. Make actions that help conserve water so they do not end or recycle waste that can be recycled, campaigning to care for the environment and so on.
