They are changes that happen on our planet as a result of human activity that has altered the composition of the atmosphere, this has resulted in increased concentrations of greenhouse gases such as carbon dioxide, methane, nitrous oxides and chlorofluorocarbons . These gases increase the temperature of the planet between 1.5 and 5.5 ° C. Some scientific experts on the subject talk about the effects that climate change can bring, such as: lack of drinking water, natural disasters such as floods, hurricanes, heat waves, periods of drought, among others. Humanity is watching with astonishment images that show on television channels about how nature attacks with strength the vulnerable and the less fortunate, knowing that a great part of this disaster is ourselves responsible for the great damage we are causing to our planet. Today, humanity is being threatened by heat waves, droughts, floods, waves of cold, tornadoes, hurricanes, earthquakes as a result of this warming Watching the news channels we see with concern the wave of cold weather that is hitting the United States in the states of Wisconsin, Texas and North Dakota, Missouri, Mississippi and Michigan that have left at least 16 people dead, it is expected that intensify and produce strong winds, causing tree falls, power outages and coastal flooding, the product of this cold wave has seen the freezing of a hydraulic tower in Iowa and the suspension of the ferry service in New York. Normally the cold is extreme almost all year, because the sun on the horizon is small and the nights are long, in some cases can last up to at least six months. These types of climates have remained in these times, but if we do not take care of it, the damage can be irreversible due to global warming. That is why we must seek a comprehensive solution, with strict policies of all those nations or countries that contribute to the emission of greenhouse gases. Some sectors that have the best chance of successfully reducing their emissions are the electric ones, through the saving and efficiency of changeable energies.
