Global warming has long become one of the great environmental challenges of the 21st century. But do you know how it originates? The answer lies in the excessive emission of greenhouse gases, which deteriorate the particles of the ozone layer until generating enormous holes through which the sun's rays penetrate with greater intensity. Although there is more. We'll tell you the rest! global-warming-definition Demonstration by climate change activists during the 15th Annual Climate Change Conference held in Denmark in December 2009. 192 countries came to negotiate a global agreement on climate change. The objective: commit to reducing global warming starting in 2012. 15 young activists from Oxfam Intermón were there. (c) Pablo Tosco / Oxfam Intermón Most of these gases are produced by excessive industrial action as well as by the use of fertilizers and chemicals in areas such as agriculture, mining, extraction of natural resources or construction, among others. However, it is good to make it clear that the warming of the Earth is not something exclusive to our time.
Since its formation, the planet has been in permanent change and has experienced an increase in its average temperature. The difference is that until recently it was a natural process; not now. Let's find out what it means! Background data: global warming in numbers The other consequence of greenhouse gases is that, by forming a thick layer in the atmosphere, they retain the heat generated on Earth . By not finding an exit to outer space, this heat settles in specific areas of the planet and generates, in turn, harmful effects Asia Mobile Number List on the environmental balance . The rise in ocean levels, the disappearance of animal species, soil erosion and the appearance of new diseases are some of these effects. In this regard, let's look at some data: In the last century, according to the Intergovernmental Panel on Climate Change (IPCC), the average temperature of the Earth has increased by 0.74 ºC. Eleven of the last twelve years have been the warmest on record (the warmest was 2015) since 1850. Greenhouse gas emissions also continue to rise. The level of carbon dioxide recorded in the atmosphere at the end of 2014 is the highest in history, according to data collected by the World Meteorological Organization (WMO).
Almost half of greenhouse gases come from commercial, industrial and residential buildings, according to the latest data collected by the IPCC . 25% of the gases come from electrical and thermal production. According to NASA, most of global warming has been generated during the last 35 years, a period that coincides with the period of greatest industrial and technological development on Earth. What could happen if we don't stop global warming? We have never before faced a problem of such magnitude. However, the scenario could be even worse if we do not implement global policies to stop warming or promote daily gestures that encourage an alternative model of consumption and development. What scenario awaits us if we don't do it? Firstly, some problems that we currently witness would be aggravated. For example, rising sea levels and an increased number of cyclones, hurricanes and floods. Also the melting of the poles , which in the last 10 years have suffered a significant decrease in their territory. The above is directly associated with the disappearance of animal species, which are displaced from their natural habitat and, in a desire for survival, migrate to other areas where they are incapable of adapting. Something similar happens with people who must abandon their places of residence due to soil erosion and pollution.
