Este evento sin precedentes est\u00e1 teniendo m\u00faltiples impactos importantes: estr\u00e9s por calor en las personas, los animales y la vegetaci\u00f3n; calidad del aire (contaminantes debido al aire caliente estable); riesgo de incendio forestal; posibilidad de deslizamientos de tierra causados \u200b\u200bpor el deshielo de los glaciares en las monta\u00f1as; da\u00f1os y mal funcionamiento de la infraestructura y los sistemas de transporte no preparados para temperaturas tan altas; y muchos otros riesgos sociales y econ\u00f3micos.<\/p>\n\n\n\n

Los servicios meteorol\u00f3gicos nacionales y locales han emitido muchas advertencias y avisos de calor y es de esperar que los servicios de alerta temprana de salud y calor limiten el n\u00famero de muertos.<\/p>\n\n\n\n

Se han batido tantos r\u00e9cords que es dif\u00edcil hacer un seguimiento.<\/p>\n\n\n\n

El r\u00e9cord canadiense de todos los tiempos se bati\u00f3 el domingo, con Lytton en la Columbia Brit\u00e1nica registrando 46,6 \u00b0 C (1,6 \u00b0 C m\u00e1s alto que el r\u00e9cord anterior establecido el 5 de julio de 1937). Menos de 24 horas despu\u00e9s, Lytton volvi\u00f3 a batir este r\u00e9cord, alcanzando los 47,9 \u00b0 C el lunes. Luego lo rompi\u00f3 por tercera vez el 29 de junio con una temperatura de 49,6 \u00b0 C.<\/p>\n\n\n\n

El r\u00e9cord de temperatura super\u00f3 el r\u00e9cord hist\u00f3rico de Las Vegas de 117 \u00b0 F \/ 47,2 \u00b0 C. Brit\u00e1nico. El calor es m\u00e1s t\u00edpico de las temperaturas de verano en el Medio Oriente que en una provincia que alberga las Monta\u00f1as Rocosas y el Parque Nacional Glacier. Existe el consiguiente riesgo de un gran derretimiento de los glaciares.<\/p>\n\n\n\n

La provincia de Columbia Brit\u00e1nica rompi\u00f3 43 r\u00e9cords hist\u00f3ricos hasta el 28 de junio, y se espera que caigan m\u00e1s.<\/p>\n\n\n\n

Armel Castellan es meteor\u00f3logo de Environment and Climate Change Canada. Dijo: A\u00fan no hemos terminado con esto.<\/p>\n\n\n\n

\u201cLos Territorios del Noroeste han registrado sus temperaturas m\u00e1s altas de todos los tiempos no solo en junio, sino en cualquier momento del a\u00f1o. Estamos estableciendo r\u00e9cords que no tienen por qu\u00e9 establecerse tan temprano en la temporada \u00ab.<\/p>\n\n\n\n

\u201cHemos tenido muchos d\u00edas seguidos de esto y cada ma\u00f1ana nos despertamos con temperaturas m\u00e1s altas. Esto es lo que es peligroso y est\u00e1 afectando a las personas durante muchos d\u00edas en los que est\u00e1n deshidratadas y hemos tenido muchos d\u00edas en los que la temperatura es m\u00e1s alta que el d\u00eda anterior \u201d, dijo el Sr. Castellan.<\/p>\n\n\n\n

\u201cLos m\u00ednimos de la noche a la ma\u00f1ana son m\u00e1s altos que nuestros m\u00e1ximos diurnos promedio para finales de junio es un gran problema. Nuestros cuerpos necesitan refrescarse y recuperarse antes de afrontar otro d\u00eda de altas temperaturas. Otra cosa en la que pensar es en la infraestructura.<\/p>\n\n\n\n

\u201cMenos del 40 por ciento de los hogares tienen aire acondicionado en la costa, la gente tiene que ir a bibliotecas y centros comerciales para encontrar un par de horas de aire acondicionado. He estado durmiendo en una tienda de campa\u00f1a para descansar un poco del calor \u201d, dijo el Sr. Castellan.<\/p>\n\n\n\n

ECCA ha emitido numerosas advertencias y advertencias sobre el calor.<\/p>\n\n\n\n

Estados Unidos de Am\u00e9rica<\/p>\n\n\n\n

Desde California y Nevada hasta el noroeste y el este hasta Montana, m\u00e1s de 14 millones de estadounidenses permanecen bajo advertencias de calor excesivo, vigilancia o advertencias de calor en el oeste.<\/p>\n\n\n\n

\u201c\u00a1Solo un tramo hist\u00f3rico de temperaturas r\u00e9cord en el noroeste! # HeatWave2021 \u201d, dijo el Servicio Meteorol\u00f3gico Nacional de EE. UU.<\/p>\n\n\n\n

Seattle estableci\u00f3 un nuevo r\u00e9cord de todos los tiempos a 104 \u00b0 F (40 \u00b0 C) el domingo y lo rompi\u00f3 el lunes con 107 \u00b0 F (41.7 \u00b0 C) Portland rompi\u00f3 el r\u00e9cord dos veces: 108 \u00b0 F (42 \u00b0 C) el s\u00e1bado 112 \u00b0 F (44,4 \u00b0 C) el domingo, seg\u00fan el Servicio Meteorol\u00f3gico Nacional de EE. UU. Muchos otros r\u00e9cords de estaciones cayeron el lunes.<\/p>\n\n\n\n

El calor es causado por una combinaci\u00f3n de un patr\u00f3n de bloqueo atmosf\u00e9rico significativo que ha dado lugar a una c\u00fapula de calor, con baja presi\u00f3n en ambos lados, y que no se mueve a lo largo de la corriente en chorro.<\/p>\n\n\n\n

Esta ola de calor se produce inmediatamente despu\u00e9s de otra hist\u00f3rica ola de calor hace menos de dos semanas que arras\u00f3 el desierto del suroeste de EE. UU. Y California con cientos de m\u00e1ximos hist\u00f3ricos.<\/p>\n\n\n\n

Calor del hemisferio norte<\/p>\n\n\n\n

mapOtras partes del hemisferio norte ya est\u00e1n experimentando condiciones excepcionales de principios de verano caluroso que se extienden desde el norte de \u00c1frica, la Pen\u00ednsula Ar\u00e1biga, Europa oriental, Ir\u00e1n y el continente indio noroccidental. Las temperaturas m\u00e1ximas diarias excedieron los 45 \u00b0 C en varios lugares y alcanzaron los 50 en el Sahara. El oeste de Libia registr\u00f3 temperaturas m\u00e1s de 10 \u00b0 C por encima del promedio de junio.<\/p>\n\n\n\n

Rusia occidental y las \u00e1reas alrededor del mar Caspio tambi\u00e9n han experimentado temperaturas inusualmente altas debido a la presencia continua de una gran \u00e1rea de alta presi\u00f3n. En algunas partes de la regi\u00f3n, incluida Mosc\u00fa, se espera que las temperaturas alcancen los 30 \u00b0 C durante el d\u00eda y se mantengan por encima de los 20 \u00b0 C durante la noche. Se espera que las \u00e1reas m\u00e1s cercanas al Mar Caspio experimenten temperaturas que alcancen los 40 \u00b0 C y se mantengan por encima de los 25 \u00b0 C por la noche. Es probable que se establezcan algunos r\u00e9cords de temperatura de todos los tiempos durante esta ola de calor.<\/p>\n\n\n\n

Cambio clim\u00e1tico<\/p>\n\n\n\n

Estas condiciones clim\u00e1ticas c\u00e1lidas de principios del verano se est\u00e1n produciendo en un contexto de cambio clim\u00e1tico inducido por el hombre, con temperaturas globales ya 1,2 \u00b0 C m\u00e1s altas que los niveles preindustriales.<\/p>\n\n\n\n

\u201cLas olas de calor son cada vez m\u00e1s frecuentes e intensas a medida que las concentraciones de gases de efecto invernadero provocan un aumento de las temperaturas globales. Tambi\u00e9n estamos notando que comienzan antes y terminan m\u00e1s tarde y est\u00e1n cobrando un precio cada vez mayor en la salud humana \u201d, dijo Omar Baddour, Jefe de la Divisi\u00f3n de Pol\u00edticas y Vigilancia del Clima de la OMM.<\/p>\n\n\n\n

Nikos Christidis es un cient\u00edfico clim\u00e1tico de la Met Office del Reino Unido. Dijo: \u201cSin el cambio clim\u00e1tico inducido por el hombre, hubiera sido casi imposible alcanzar temperaturas medias r\u00e9cord de junio en el oeste de los Estados Unidos, ya que las posibilidades de que ocurra de forma natural son una vez cada decenas de miles de a\u00f1os. En el clima actual, un junio extremadamente caluroso es com\u00fan y es probable que ocurra dos veces en tres d\u00e9cadas. Sin embargo, un an\u00e1lisis de muchos modelos inform\u00e1ticos sugiere que para finales de siglo estas temperaturas extremas ser\u00e1n m\u00e1s probables que no. Se estima que la influencia humana ha aumentado la probabilidad de un nuevo r\u00e9cord varios miles de veces \u201d, dijo.<\/p>\n\n\n\n

El Informe especial del Grupo Intergubernamental de Expertos sobre el Cambio Clim\u00e1tico sobre el calentamiento global de 1,5 \u00b0 C conten\u00eda informaci\u00f3n sobre el cambio clim\u00e1tico y el bienestar humano.<\/p>\n\n\n\n

Se prev\u00e9 que los riesgos relacionados con el clima para la salud, los medios de vida, la seguridad alimentaria, el suministro de agua, la seguridad humana y el crecimiento econ\u00f3mico aumenten con el calentamiento global de 1,5 \u00b0 C y aumenten a\u00fan m\u00e1s con 2 \u00b0 C. Limitar el calentamiento a 1,5 \u00b0 C en lugar de 2 \u00b0 C podr\u00eda resultar en 420 millones de personas menos expuestas a olas de calor severas, dijo.<\/p>\n\n\n\n

En 2018, las personas vulnerables mayores de 65 a\u00f1os experimentaron un r\u00e9cord de 220 millones m\u00e1s de exposiciones a olas de calor, que el promedio de la l\u00ednea de base de 1986-2005, seg\u00fan el informe de la OMM sobre el estado del clima mundial en 2019.<\/p>\n\n\n\n

La Oficina Conjunta sobre Clima y Salud de la OMM y la Organizaci\u00f3n Mundial de la Salud trabaja activamente para proteger la salud de las personas de este gran peligro. La OMM es uno de los socios fundadores de la Red mundial de informaci\u00f3n sobre salud y calor.<\/p>\n\n\n\n

An exceptional and dangerous heatwave is baking the Northwestern USA and Western Canada in areas which are more synonymous with the cold. Temperatures have reached more than 45.0\u00b0C on consecutive days, with extremely warm nights in between.<\/p>\n\n\n\n

\"twitt\"<\/figure>\n\n\n\n

This unprecedent event is having multiple major impacts:  heat stress in people, animals and vegetation; air quality (pollutants due to hot stable air); forest fire risk; possibility of landslides caused by glacier melting in mountains; damages and malfunctioning of infrastructure and transport systems not prepared for such high temperatures; and many other social and economic risks.<\/p>\n\n\n\n

National and local meteorological services have issued many heat warnings and advisories and it is to be hoped that heat-health early warning services will limit the death toll.<\/p>\n\n\n\n

So many records have been broken that it is difficult to keep track.<\/p>\n\n\n\n

The all-time Canadian record was broken on Sunday, with Lytton in British Columbia recording 46.6\u00b0C (1.6\u00b0C higher than the previous record set on 5 July 1937). Less than 24 hours later, Lytton broke this record again, reaching 47.9\u00b0C on Monday. It then broke it for a third time on 29 June with a temperature of 49.6\u00b0C.<\/p>\n\n\n\n

The temperature record surpassed Las Vegas’ all-time record high of 117\u00b0F\/47.2\u00b0C. British. The heat is more typical of summer temperatures in the Middle East than a province which is home to the Rocky Mountains and Glacier National Park. There is a consequent risk of high glacier melt.<\/p>\n\n\n\n

The province of British Columbia broke 43 all-time records as of 28 June, with more expected to tumble.<\/p>\n\n\n\n

\"Twitt\"\u201cWords cannot describe this historic event,\u201d tweeted Environment and Climate Change Canada British Colombia.<\/p>\n\n\n\n

Armel Castellan is a meteorologist with Environment and Climate Change Canada. He said: We are not done with this yet.<\/p>\n\n\n\n

\u201cThe North West Territories have recorded their all-time highest temperatures not just in June, but any point in the year.  We are setting records that have no business in being set so early in the season.\u201d<\/p>\n\n\n\n

\u201cWe have had many days of this in a row and each morning we wake up to a higher temperatures. This is what is dangerous and it is affecting people throughout many days where they are dehydrated and we have had many days where the temperature is higher than the day before,\u201d Mr Castellan said.<\/p>\n\n\n\n

\u201cOvernight lows being higher than our average daytime highs for late June is a really big deal. Our bodies need to cool off and recover before taking on another day of high temperatures. Another thing to think about is the infrastructure.<\/p>\n\n\n\n

\u201cFewer than 40 per cent of homes have air conditioning on the coast, people are having to go to libraries and shopping malls to find a couple of hours of air conditioning. I have been sleeping in a tent to get some respite from the heat,\u201d said Mr Castellan.<\/p>\n\n\n\n

ECCA has issued numerous heat warnings and advisories.<\/a><\/p>\n\n\n\n

United States of America<\/strong><\/p>\n\n\n\n

From California and Nevada into the Northwest<\/a> and east into Montana, over 14 million Americans remain under either excessive heat<\/a> warnings, watches or heat advisories in the West<\/a>.<\/p>\n\n\n\n

\u201cJust a historic stretch of record shattering temperatures in the Northwest! #HeatWave2021<\/a>,\u201d said the U.S. National Weather Service.<\/p>\n\n\n\n

Seattle set a new all-time record at 104\u00b0F (40\u00b0C) on Sunday and broke that on Monday with 107\u00b0F (41.7\u00b0C) Portland broke the record twice – 108\u00b0F (42\u00b0C) on Saturday 112\u00b0F (44.4\u00b0C) on Sunday, according to the US National Weather Service. Many other station records tumbled on Monday.<\/p>\n\n\n\n

The heat is being caused by a combination of a significant atmospheric blocking pattern which has led to a heat dome, with low pressure either side, and which is not being moved along by the jet stream.<\/p>\n\n\n\n

This heat wave comes on the heels of another historic heat wave less than two weeks ago that baked the U.S. Desert Southwest and California with hundreds of record highs. <\/p>\n\n\n\n

Northern hemisphere heat <\/strong><\/p>\n\n\n\n

\"map\"Other parts of the northern hemisphere are already experiencing exceptional early hot summer conditions extending from the north Africa, Arabian Peninsula, eastern Europe, Iran and the north-western indian continent. Maximum daily temperatures exceeded 45\u00b0C in several locations and reaching 50\u2019s in the Sahara. Western Libya saw temperatures more than 10\u00b0C above average for June<\/a>.<\/p>\n\n\n\n

Western Russia and areas around the Caspian Sea have also seen unusually high temperatures due to the continued presence of a large area of high pressure. In parts of the region including Moscow temperatures are expected to reach the mid-30s\u00b0C by day, remaining above 20\u00b0C by night. Areas nearer the Caspian Sea are expected to experience temperatures reaching the mid 40s\u00b0C and remaining above 25\u00b0C at night. It is likely that some all-time temperature records will be set during this heatwave.<\/p>\n\n\n\n

Climate Change<\/strong><\/p>\n\n\n\n

These early summer hot weather conditions are taking place in human-induced climate change background, with global temperatures are already 1.2\u00b0C higher than the pre-industrial levels.<\/p>\n\n\n\n

\u201cHeatwaves are becoming more frequent and intense as greenhouse gas concentrations lead to a rise in global temperatures. We are also noticing that they are starting earlier and ending later and are taking an increasing toll on human health,\u201d said Omar Baddour, Head of WMO\u2019s Climate Monitoring and Policy Division.<\/p>\n\n\n\n

Nikos Christidis is a climate scientist with the UK\u2019s Met Office. He said: \u201cWithout human-induced climate change, it would have been almost impossible to hit such record-breaking mean June temperatures in the Western United States as the chances of natural occurrence is once every tens of thousands of years. In the present-day climate getting an extremely hot June is common and is likely to occur twice in three decades. However, an analysis from many computer models suggests that by the end of the century these extreme temperatures are more likely than not. Human influence is estimated to have increased the likelihood of a new record several thousand times,\u201d he said.<\/p>\n\n\n\n

The Intergovernmental Panel on Climate Change Special Report on Global Warming of 1.5\u00b0C contained information on climate change and human welfare. <\/p>\n\n\n\n

Climate-related risks to health, livelihoods, food security, water supply, human security, and economic growth are projected to increase with global warming of 1.5 \u00b0C and increase further with 2 \u00b0C. Limiting warming to 1.5 \u00b0C rather than 2 \u00b0C could result in 420 million fewer people being exposed to severe heatwaves, it said.<\/p>\n\n\n\n

In 2018, vulnerable people over the age of 65 experienced a record 220 million more heatwave exposures, than the average for the baseline of 1986\u20132005, according to WMO\u2019s report on the State of the Global Climate in 2019.<\/p>\n\n\n\n

The WMO and World Health Organization Joint Office on Climate and Health works actively to protect people\u2019s health from this major hazard. WMO is one of the founding partners of the Global Heat-Health Information Network<\/a>.<\/p>\n\n\n\n
