We explain what global warming is, what its causes and consequences are. How to avoid and prevent global warming.

This phenomenon gradually generates new deserts on the planet.

What is global warming?

It is known as global warming, along with the climate change, to one of the major ecological concerns of the late twentieth and early twenty-first centuries, consisting of the sustained increase in temperature average of planet Earth over a century, which shows numerous effects on climatic behavior and on the average water level oceanic, given the gradual melting of the polar ice.

The record of global warming is alarming and has been confirmed by numerous scientific tests. However, there is no absolute consensus regarding the causes of this increase in temperature. The dissemination of the subject in specialized press and observation of the effects of climate change on various latitudes terrestrial states reflect that it is one of the greatest concerns for the future of the humanity.

So much so that the United Nations has commissioned some of its representatives to lead a necessary debate, which aims to protect the future of humanity from possible climate catastrophes. However, the thesis that blames human industrial activity for the increase in greenhouse effect on the atmosphere (As the CO2), is the least accepted in countries such as China and the United States, precisely those with the highest emission of these gases into the atmosphere.

While debates are taking place regarding what causes it and how it can be reversed or at least slowed down, the effects of global warming and climate change are being seen throughout the planet, turning wetlands into deserts and gradually but dramatically altering the thermal balance of the planet.

Causes of global warming

Sun, varies its position slowly over the centuries, and this leads to humanly imperceptible cycles of warming and freezing, known as ice ages.Thus, cold cycles would cause polar growth, while warm cycles would cause it to melt.

Human activity. The most accepted of both theories, which does not completely rule out the influence of glacial cycles on climate change, assures that the responsibility direct human influence on the acceleration of warming, whose upward curve coincides, not coincidentally, with the onset of Industrial Revolution. This explanation says that the gases produced by the industry Y farming Humans accumulate in the atmosphere at a higher rate than it can dispose of, and generate a screen that prevents the dissipation of the heat into space, increasing the temperature as in a greenhouse.

Consequences of global warming

air and in seawater it would cause the melting of glaciers and permafrost in the polar regions, which would add fresh water to the ocean and it would slowly raise the level of its waters. Thus, flooding and the expansion of the coastline would submerge cities whole under water.

Extreme weather events. The imbalance of temperatures affects the extremes of certain climates: the hot ones are hotter and the cold ones much colder, which is accompanied by more extreme meteorological phenomena: more intense rains, more devastating hurricanes, etc.

Abrupt ecological changes. Changes in climate engender changes in ecological niches, some gradually and others much more abruptly. For example, glacial melt releases not only water, but gases such as methane and carbon dioxide, the increase of which is added to the greenhouse effect and leads to ocean acidification, affecting millions of living beings.

Landslides. Increases in the rate of precipitation or melting of perennial snows in the moutains can cause humidification and liquefaction of the I usually, carrying avalanches and other potentially lethal landslides.

New deserts. Too hot temperatures and prolonged drought destroy the local flora and gradually generate new deserts, little usable for human and animal life.

How to avoid and prevent global warming?

The first step towards designing a strategy To deal with climate change is obviously to acknowledge it. Theories regarding human non-responsibility in the phenomenon have the disadvantage of promoting a attitude carefree in the citizens of the most industrialized countries, responsible for the highest greenhouse gas emissions.

Only by reducing the amount of carbon that is released into the atmosphere, through significant industrial reductions and the promotion of business laws to defend the environment, the planet would be given the chance to reverse the gas load and regain a thermal balance. None of this would be short-term, of course, but it would take more than a decade to notice the change.

On the other hand, adaptation to climate change is a response to minimize material damage and human losses, through barriers and structures urban areas that minimize the damage caused by extreme weather events.
