Warming of the Earth and Its Consequences concerned

Only after the last tree is cortado.Solo after the last river is poisoned. Only after the last fish is apresado.Solo then you know that money can not eat. Prophecy India.

Increasingly alarming what might happen in the future to a humanity that will not stop their growth, in the proper management of energy to the effects it generates in its habitat, its use, since the consequences are already originating, where increasingly deteriorating environment, endangering their survival. It is important that countries through campaigns, actions, programs to engage their citizens, the world to collaborate with the responsibility of the non-contamination and proper use of energy, in order to make a reality the preservation of species, if you really want to preserve an environment in which to live, without fear of destruction. The problem is so serious that can not be avoided, while remaining in this dimension where we are obliged to cooperate with our media, advertising everything that can happen in order to provide greater evils. Hence the importance of remembering the remark brings us Gaia Vince, an interesting paper on this subject of Gaia Vince, published in New Scientist, where he also valid concern, that an average warming of the globe by 4 ° C would make the world beyond recognition.

In fact, human activity and has had such an impact that some people proposed to describe the period that began in the eighteenth century as a new geological era marked by human activity. "It can be considered the Anthropocene," says Nobel Prize winner and chemist Paul Crutzen of the atmosphere, the Max Planck Institute, Germany. The temperature increases 4 ° C is very possible. The report of the Intergovernmental Panel on Climate Change (IPCC, according to its acronym in English) in 2007, whose findings are considered conservative, predicted a rise of between 2 ° and 6 ° 4C this century. And in August 2008, Bob Waston, former chairman of the IPCC, warned that the world should work on strategies to "prepare for a warming of 4 ° C". Depending on the model, we could meet up like that for 2100. Some scientists believe that arrive in 2050. If this happens, the consequences for life on Earth would be so terrible that many scientists contacted for this article preferred not to contemplate them, and just felt that we should concentrate on reducing emissions to a level that the increase in temperature has only place in our nightmares.

The last time the world experienced a temperature increase of this magnitude was 55 million years ago. At that time, the culprits were large areas of frozen methane and chemically bound, which released the deep ocean in explosive bursts filled the atmosphere with around 5 gigatonnes of carbon. This caused the temperature increases about 5 or 6 ° C appeared in the rainforests ice-free polar regions and oceans became so acidic because carbon dioxide was a large reduction in aquatic life. The seas were up to 100 feet above the current level and desert stretched from southern Africa to Europe. Add Vince, if i well the exact changes will depend on how quickly they produce the rising temperatures and melting polar ice how then can we hope to develop a similar scenario. The first problem is that many of the places where people live and food is produced will be unusable. Rising sea levels (due to thermal expansion of oceans, melting glaciers and major storms) current flood coastal regions with two feet of water, and possibly much more if the Greenland ice and part of Antarctica to melt.

Half of the world surfaces are in the tropics, between 30 ° and -30 ° latitude, and these areas are particularly vulnerable to climate change. India, Bangladesh and Pakistan, for example, will have shorter monsoons, but harder, with even more disastrous floods that those who suffer today. But as the Earth is warmer, the water will evaporate faster and cause drought across Asia. The lack of potable water will be felt across the globe, with high temperatures that will reduce soil moisture in China, the southwestern United States, Central America, most of South America and Australia. All the great deserts expand, and the Sahara will come right up to central Europe. The retreat of the glaciers dry up European rivers from the Danube to the Rhine, with similar effects in other mountain regions, like the Peruvian Andes, the Himalayan and Karakoram, which, as a result, it will supply water to Afghanistan, Pakistan, China, Bhutan, India and Vietnam. Vince adds us that all this will lead to the creation of two latitudinal dry belts where it will be impossible to live, according to Syukur Manabe, University of Tokyo, Japan, and colleagues.

One will cover Central America, southern Europe and northern Africa, southern Asia and Japan. The other, Madagascar, South Africa, the Pacific islands, and most of Australia and Chile The only places that will be enough water in high latitudes. "Everything in that region will grow like crazy. It is there where life refuge, says James Lovelock, a former NASA scientist and creator of the Gaia theory, which describes Earth as a self-regulating entity. The rest of world will be a great desert with few oases. " Given this reality is of concern when it appears that "Humans are in a difficult position, and I think we are smart enough to handle what's coming. I think we will survive as a species, but the mortality is great during this century -says James Lovelock, -. At the end of it, the amount will be a billion or less. " To survive, we have to do something radical: rethink our society not in geopolitical terms, but the distribution of resources. "We always thought that each country has to have food, water and energy to sustain themselves, says Peter Cox, who studies the dynamics of climate systems at the University of Exeter, UK.

We have to look at the world and see where the resources and then plan the population, food production and energy from them. "Removing the policy of the equation may seem unrealistic: conflict over resources are likely to increase with the climate change, and political leaders will not stop just because their power. However, overcome political problems may be our only solution. "It's too late for us," says President Anote Tong of Kiribati, an island Micronesia is sinking in that scheduled gradual migration to Australia and New Zealand. "We must do something drastic to end national boundaries." Even if we could evacuate the entire world population in Canada, Alaska, Britain, Russia and Scandinavia , this would be one of the few regions with access to water, which would be valuable areas for agriculture, as well as the last oases for many species, so people have to live in compact high-rise buildings. Living in such a short space bring its own problems, since the diseases spread easily in crowded populations. In addition, since water is scarce, food production will have to be much more efficient.

Definitely, it takes more responsibility for the dwellers on the planet, but of course, it is governments that must be guarantors that the surrounding culture will become a reality, to control all those factors deteriorating the environment and involves can be given to what really exposes much reality Gaia Vince, who already is troubling, disturbing Consider as add, if we use land, energy, food and water efficiently, the entire population has a chance of survival if we have time and willingness to adapt. Much of the Earth's biodiversity will disappear because the species can not adapt fast enough to high temperatures, lack of water, loss of ecosystems or because humans have eaten it.
