Tema 1: Riesgos existenciales para la sostenibilidad

En este mundo que cambia rápidamente, todos aspiramos a sentirnos seguros. Sin embargo, para todos nosotros, hay varias amenazas que se enmarcan como Planeta (cambio climático, pérdida de biodiversidad, metoerites, volcanes, mega terremotos), Gente (Pandémicas, aire limpio, escasez de agua, contaminación de residuos, proporcionando seguridad alimentaria), Prosperidad (amenazas de IA, crecimiento insostenible, aumento de las desigualdades) y Paz (guerras, aniquilación nuclear) que nos aleja de vivir seguros y seguros.

La humanidad es ahora la fuerza motriz más grande del cambio en el planeta. La humanidad ha llegado a ocho mil millones de personas, y tiene efecto en el desarrollo. A medida que los niveles de vida continúan aumentando, los ingenieros se encuentran bajo creciente presión para satisfacer demandas ilimitadas de la humanidad con fuentes limitadas de la tierra.  En esta nueva realidad, el desarrollo debe ser capaz de navegar por la complejidad. Para la sostenibilidad, debemos cuidar de todos, no solo de nosotros, sino de nuestro medio ambiente y de las personas que nos persiguen. Las soluciones climáticas necesitan justicia, equidad, buceo e inclusión. Esto significa respetar los más altos valores éticos y garantizar la participación equitativa de mujeres y hombres e integrar la dimensión de género en el contenido del desarrollo. Hacer frente a los desafíos no es una tarea fácil. Queremos sostenibilidad y seguridad, queremos privacidad y seguridad, queremos crecimiento económico y sostenibilidad. Queremos todas estas cosas al mismo tiempo. La Ingeniería Sostenible, como práctica, pone un fuerte énfasis en el diseño, desarrollo y mejora de sistemas, procesos y productos de ingeniería con mínimo impacto ambiental y máximos beneficios sociales y económicos.

The Earth is believed to have come into existence roughly 4.5 billion years ago. Homo sapiens, the scientific name for modern humans, have been on the planet for about 200,000 years. However, human activities have had a negative impact on the environment, such as deforestation, pollution, greenhouse gas emissions, habitat destruction, and overexploitation of resources.

Throughout Earth’s long history, it has experienced natural climate fluctuations, including ice ages, droughts, and abrupt shifts between warm and cool periods. However, the current climate change we are witnessing is largely attributed to the anthropogenic, or human-caused, effect. Unlike the historical natural climate variations, this contemporary change is primarily driven by human activities. The main reason of current climate change is Industrial evaluation. The rapid industrial and technological advancements of the Anthropocene era have led to increased greenhouse gas emissions, deforestation, and other activities that trap heat in the Earth’s atmosphere, resulting in global warming and significant alterations to our planet’s climate patterns. According to scientific data from the industrial evolution, the temperature of earth has been increased by 1 °C. There is a strong correspondence between temperature and the concentration of carbon dioxide in the atmosphere observed during the glacial cycles of the past several hundred thousand years.  When the carbon dioxide concentration goes up, temperature goes up. The  amount of carbon particles on the earth now it is around 421 ppm which is the same 30000000 years ago. In recent years, world leaders have stressed the need to limit global warming to 1.5°C by the end of this century. That’s because the UN’s Intergovernmental Panel on Climate Change indicates that crossing the 1.5°C threshold risks unleashing far more severe climate change impacts, including more frequent and severe droughts, heatwaves and rainfall.

Global warming is very very visible. A catastrophic die-off of emperor penguin chicks has been observed in the Antarctic, with up to 10,000 young birds estimated to have been killed.

The sea-ice underneath the chicks melted and broke apart before they could develop the waterproof feathers needed to swim in the ocean.

The birds most likely drowned or froze to death.

Researchers discovered harvests began shifting dramatically earlier during the latter half of the 20th century. These shifts were caused by changes in the connection between climate and harvest timing. While earlier harvests from 1600 to 1980 occurred in years with warmer and drier conditions during spring and summer, from 1981 to 2007 warming attributed to climate change resulted in earlier harvests even in years without drought.

El impacto del cambio climático y los peligros ambientales a gran escala se están intensificando y afectando cada vez más a las economías y los medios de subsistencia. Por esta razón, en 2015 los líderes del mundo se unieron para acordar una promesa de que en los próximos 15 años, las vidas de miles de millones de personas mejorarán sin que nadie se quede atrás.  Esa promesa son los objetivos de desarrollo sostenible, los ODS.

Many dangerous feedback loops make climate action more urgent: Existential risks reinforce each other; they are transgressional in terms if district and geography. More specifically, developing nations experienced deaths rates more than four times higher than developed ones regarding to environmental issues. It triggers the migration of nations from south to north and from east to west. They have tipping point; The impact of climate change and large-scale environmental hazards is intensifying and taking a growing toll on economies and livelihoods. A number of tipping points in climate change will soon be or are already being reached, triggering feedback loops with catastrophic consequences for life on Earth. Technology overlap with this risks. This is the time of crisis and of hope.
