Today, October 24, is World Climate Change Day. This day was proposed by the United Nations in order to raise awareness about the negative consequences of the effects of climate change on our planet.
Climate change and global warming is a reality that does not understand borders, it becomes a global challenge. The greenhouse effect is a natural process that allows the Earth to maintain the conditions necessary to approach life. Currently greenhouse gas emissions are at the highest level in history, precisely in 2019 was the second hottest year of all time and marked the end of the hottest decade (2010-2019) which has never been registered.
Climate change is affecting all countries around the world; altering national economies, sea levels are rising and weather phenomena are becoming more extreme. Hence the importance of knowing and fighting to meet all the goals proposed by United Nations SDG 13.
SDG 13: CLIMATE ACTION
Chapter 13 of the 2030 Agenda makes direct reference to Climate Change it is intrinsically related to the remaining 16 Sustainable Development Goals on the Agenda. The purpose in this case is to take urgent measures to combat environmental problems and their effects, because it is a consequence of human activity and is threatening the way of life of all individuals on Earth and the future of planet. To deal with the problem we must act immediately, building a sustainable world from all of us to everyone.
The greenhouse effect is a natural process that allows the earth to maintain the conditions necessary to approach life: the atmosphere retains some of the heat of the sun; without the greenhouse effect, the average temperature of the planet would be 18ºC below zero. The problem comes when human activities, for example; the exponential increase of the population or the destruction of the marine and terrestrial ecosystems, increase the emission of greenhouse gases to the atmosphere and this one, retains more heat than the necessary one, causing therefore that the average temperature of the planet increases and what is popularly known as global warming occurs.
Rising sea levels, extreme weather events, heat waves, droughts and floods are some of the manifestations of climate change, with a profound negative impact on the economies of countries and people's lives.
In combating climate change, the 2030 Agenda focuses on reducing the effects as well as on adaptation and early warning, always taking into account the most disadvantaged countries and people in a vulnerable situation. It emphasizes the importance of human and institutional education, awareness and training and the inclusion of climate measures in countries' policies. Climate change is one of the main challenges for the sustainability of the planet.
It is an urgent issue for which there are no borders and joint action is needed, although tackling climate change requires many economic resources, the cost otherwise it would be higher, as the cost we could have on ecosystems, the economy and people’s lifes, would be irreversible.
