These changes to climate are bringing increases to the occurrence of <a href=\"https:\/\/public.wmo.int\/en\/media\/news\/2019-starts-extreme-high-impact-weather\">extreme events<\/a>, and have also been connected to recent reductions in the presence of arctic sea ice <sup>9<\/sup>. A world without this ice could bring about changes to the parts of the earth where agriculture is possible. While parts of the current Mediterranean landmass (such as central Chile or southern Europe) are likely to become lost to desertification under extreme climate warming and lack of water, parts of Greenland, and current arctic tundra could become more hospitable and permit crop development. However, if that sounds nice, think for a moment about the potential knock on effects about global heat transport which is balanced by the input of freshwater into the oceans (such as the <a href=\"https:\/\/www.carbonbrief.org\/slowdown-atlantic-conveyor-belt-could-trigger-two-decades-rapid-global-warming\">North Atlantic conveyor belt theory<\/a> <sup>10<\/sup>). Such reduction in heat transport between equator and pole leads to the possibility of permanently cold northerly regions and permanently hot desert regions closer to the equator. This could potentially limit these new growing geographies and drastically reduce the habitable places of our planet&#8230; sounds less fun for a continuously rising human populace, right?<\/p>\n<p>[\/et_pb_text][\/et_pb_column][et_pb_column _builder_version=&#8221;4.24.3&#8243; _module_preset=&#8221;default&#8221; type=&#8221;1_2&#8243;][et_pb_blurb title=&#8221;Figure 1&#8243; image=&#8221;https:\/\/glaciareschilenoss3.s3.us-west-1.amazonaws.com\/wp-content\/uploads\/2024\/05\/22182449\/Mapa-mundial-aumento-mar.jpg&#8221; _builder_version=&#8221;4.24.3&#8243; _module_preset=&#8221;default&#8221; title_text=&#8221;Mapa mundial aumento mar&#8221; hover_enabled=&#8221;0&#8243; sticky_enabled=&#8221;0&#8243; header_font=&#8221;Montserrat||||||||&#8221; body_font=&#8221;Montserrat||||||||&#8221; body_font_size=&#8221;12px&#8221;]<\/p>\n<p><em>Europe underwater.

A world without this ice could bring about changes to the parts of the earth where agriculture is possible. While parts of the current Mediterranean landmass (such as central Chile or southern Europe) are likely to become lost to desertification under extreme climate warming and lack of water, parts of Greenland, and current arctic tundra could become more hospitable and permit crop development. However, if that sounds nice, think for a moment about the potential knock on effects about global heat transport which is balanced by the input of freshwater into the oceans (such as the <a href=\"https:\/\/www.carbonbrief.org\/slowdown-atlantic-conveyor-belt-could-trigger-two-decades-rapid-global-warming\">North Atlantic conveyor belt theory<\/a> <sup>10<\/sup>). Such reduction in heat transport between equator and pole leads to the possibility of permanently cold northerly regions and permanently hot desert regions closer to the equator. This could potentially limit these new growing geographies and drastically reduce the habitable places of our planet&#8230; sounds less fun for a continuously rising human populace, right?<\/p>\n<p>&nbsp;<\/p>\n<p>Cited information:<\/p>\n<p><sup>1<\/sup> 10 Critical Water Scarcity Facts We Must Not Ignore.

Tal vez no sea probable que un colapso social completo aumente solo por la falta de glaciares, pero la escasez de agua para ciudades enteras es un enorme problema socioecon\u00f3mico que est\u00e1 por suceder. En la actualidad, el consumo humano de agua como un producto no se trata con la seriedad que merece, y con frecuencia puede desviarse, contaminarse o mal administrarse <sup>1<\/sup>. Muchas ciudades situadas en la base de estas verdaderas \"torres de agua\" de monta\u00f1a se enfrentar\u00e1n a graves inseguridades futuras cuando el almacenamiento de agua en los glaciares se reduzca y desaparezca por completo. Esto ya ha comenzado a ocurrir en Bolivia <sup>2<\/sup> y parece probable que ocurra en partes del centro de Chile, Per\u00fa <sup>3<\/sup>, India, Pakist\u00e1n, Nepal, China as\u00ed como Afganist\u00e1n <sup>4,5<\/sup>, por nombrar solo algunos. La grave escasez de agua en una ciudad entera (que no est\u00e1 relacionada con los glaciares) ya ha cambiado la percepci\u00f3n de algunos habitantes de las ciudades sobre el valor de este recurso y lo que significa vivir con 15 litros de agua por d\u00eda <sup>6<\/sup>. Adem\u00e1s, como recurso total, perderemos la mayor parte del agua dulce restante disponible para nosotros ya que se pierde en el oc\u00e9ano, de agua salada. Actualmente, solo el 0,3% del agua en la tierra se encuentra en una forma segura para beber. M\u00e1s del 68% de este suministro de agua dulce se mantiene suspendido en el hielo <sup>7<\/sup>.

Sin embargo, si consideramos un mundo con cero hielo incluso en los polos (por lo que no habr\u00eda capas de hielo en Groenlandia o Ant\u00e1rtica), eso ser\u00eda mucho derretimiento. Las estimaciones de las capas de hielo polar completamente derretidas muestran un aumento de ~ 65 m en el nivel medio global del mar <sup>8<\/sup>. Piense en un futuro cercano en el que tengamos 20 cm adicionales de altura media del mar... esto sumergir\u00eda muchas zonas de comunidades costeras, como las de Bangladesh, Florida y el norte de Europa por nombrar algunas. 65 m realmente ser\u00eda un mundo diferente de lo que vemos ahora (Figura 1). \u00a1Los costos sociales, pol\u00edticos y econ\u00f3micos de tales migraciones masivas ser\u00edan realmente muy significativos!<\/p>[caption id=\"attachment_4048\" align=\"aligncenter\" width=\"533\"]<img class=\"wp-image-4048\" src=\"https:\/\/www.glaciareschilenos.org\/wp-content\/uploads\/2020\/03\/7.World_map_rise_sea.jpg\" alt=\"\" width=\"533\" height=\"400\" \/> <em>Figura 1.

Maybe a complete societal collapse is unlikely to rise from the lack of glaciers alone, but water shortages for entire cities are a huge socio-economic problem waiting to happen. At current, human consumption of water as a commodity is not treated with the seriousness it deserves, and can often by diverted, polluted or mis-managed <sup>1<\/sup>. Many cities at the base of mountain \u2018water towers\u2019 will face serious future insecurities as long term water storage from glaciers are diminished and disappear completely. This has begun to occur already in cases in Bolivia <sup>2<\/sup> and looks likely to occur for parts of central Chile, Peru <sup>3<\/sup>, India, Pakistan, Nepal, China and Afghanistan as well <sup>4,5<\/sup>, to name but a few. Serious citywide water shortages not related to glaciers have already changed the perception of some urbanites on the preciousness of such a resource and what it means to live in 15 liters of water per day <sup>6<\/sup>. What\u2019s more, as a total resource, we will lose the majority of the remaining freshwater available to us as it is lost to the salt ocean. Currently, only 0.3% of water on earth is in a form safe to drink. Over 68% of this freshwater supply is held suspended in ice <sup>7<\/sup>. You do the math.<\/p><p>\u00a0<\/p><h4><b>2) Dramatic sea level rise<\/b><\/h4><p>The contribution of small mountain glaciers to total sea level rise is relatively small (estimated at 0.41 m <sup>8<\/sup>). However, if we consider a world with zero ice, even at the poles (so no Greenland or Antarctic ice sheets), that\u2019s a lot of melting. Estimates of completely melted polar ice sheets show a ~65 m rise in global average sea level <sup>8<\/sup>. Think about a near future world where we have a likely 20 cm of addition average sea height.... this already is set to submerge many coastal communities, such as those in Bangladesh, Florida and Northern Europe to name a few. 65 m would really be a different world from what we see right now (Figure 1). The social, political and economic costs of such mass migrations would be very significant indeed!<\/p>[caption id=\"attachment_4048\" align=\"aligncenter\" width=\"533\"]<img class=\"wp-image-4048\" src=\"https:\/\/www.glaciareschilenos.org\/wp-content\/uploads\/2020\/03\/7.World_map_rise_sea.jpg\" alt=\"\" width=\"533\" height=\"400\" \/> <em>Figure 1.

These changes to climate are bringing increases to the occurrence of <a href=\"https:\/\/public.wmo.int\/en\/media\/news\/2019-starts-extreme-high-impact-weather\">extreme events<\/a>, and have also been connected to recent reductions in the presence of arctic sea ice <sup>9<\/sup>. A world without this ice could bring about changes to the parts of the earth where agriculture is possible. While parts of the current Mediterranean landmass (such as central Chile or southern Europe) are likely to become lost to desertification under extreme climate warming and lack of water, parts of Greenland, and current arctic tundra could become more hospitable and permit crop development. However, if that sounds nice, think for a moment about the potential knock on effects about global heat transport which is balanced by the input of freshwater into the oceans (such as the <a href=\"https:\/\/www.carbonbrief.org\/slowdown-atlantic-conveyor-belt-could-trigger-two-decades-rapid-global-warming\">North Atlantic conveyor belt theory<\/a> <sup>10<\/sup>). Such reduction in heat transport between equator and pole leads to the possibility of permanently cold northerly regions and permanently hot desert regions closer to the equator.
