Pe 21 iunie, media global\u0103 a temperaturii la suprafa\u021ba m\u0103rii a ajuns la 21,0\u00b0C, conform m\u0103sur\u0103torilor realizate de Copernicus Climate Change Service<\/span><\/span> \u0219i Copernicus Marine Service<\/span><\/span>. Este un nou record, dep\u0103\u0219ind valorile din 2023 (20,83\u00b0C) \u0219i 2024 (20,86\u00b0C) cu aproximativ 0,1\u00b0C.<\/p>\n

De\u0219i diferen\u021ba pare mic\u0103, chiar \u0219i varia\u021biile minore de temperatur\u0103 pot produce efecte majore: dezechilibre \u00een ecosistemele marine, accelerarea cre\u0219terii nivelului m\u0103rii \u0219i declan\u0219area unor fenomene meteo extreme pe uscat, potrivit EuroNews<\/a>.<\/p>\n

Cre\u0219terea este par\u021bial influen\u021bat\u0103 de instalarea fenomenului El Ni\u00f1o \u00een Pacificul ecuatorial, \u00eens\u0103 speciali\u0219tii spun c\u0103 acesta se suprapune peste o tendin\u021b\u0103 de durat\u0103 generat\u0103 de schimb\u0103rile climatice.<\/p>\n

\u00cen ultimii trei ani, temperaturile oceanelor din afara zonelor polare au fost cu 0,35\u00b0C p\u00e2n\u0103 la 0,73\u00b0C peste media pe termen lung, potrivit Copernicus.<\/p>\n

\u201eCondi\u021biile actuale pot indica \u00eenceputul unei noi faze, din nou \u00eentr-un teritoriu necunoscut\u201d, a declarat Carlo Buontempo, director al Copernicus Climate Change Service<\/span><\/span> \u00een cadrul European Centre for Medium-Range Weather Forecasts<\/span><\/span>.<\/p>\n

El a avertizat c\u0103, \u00een lunile urm\u0103toare, sunt probabile noi recorduri de temperatur\u0103.<\/p>\n

Situa\u021bia se aliniaz\u0103 cu estim\u0103rile recente ale ONU, care indic\u0103 o probabilitate de 91% ca cel pu\u021bin unul dintre urm\u0103torii cinci ani s\u0103 dep\u0103\u0219easc\u0103 pragul de \u00eenc\u0103lzire de 1,5\u00b0C stabilit prin Acordul de la Paris. De asemenea, exist\u0103 o probabilitate de 86% ca unul dintre acei ani s\u0103 devin\u0103 cel mai cald \u00eenregistrat.<\/p>\n

\u201eFenomene extreme f\u0103r\u0103 precedent\u201d<\/h2>\n

Impactul apelor oceanice mai calde nu r\u0103m\u00e2ne limitat la oceane. Acestea cresc energia din atmosfer\u0103, intensific\u0103 furtunile, favorizeaz\u0103 evaporarea \u0219i pot duce la ploi abundente \u0219i inunda\u021bii.<\/p>\n

\u00cenc\u0103lzirea oceanelor contribuie \u0219i la cre\u0219terea nivelului m\u0103rii, topirea ghe\u021barilor \u0219i stresarea ecosistemelor marine. De asemenea, favorizeaz\u0103 valuri de c\u0103ldur\u0103 marine mai frecvente \u0219i mai intense, cu efecte asupra pescuitului, economiilor costiere \u0219i temperaturilor de pe uscat.<\/p>\n

Fenomenul El Ni\u00f1o amplific\u0103 aceste efecte, redistribuind c\u0103ldura \u00een atmosfer\u0103 \u0219i modific\u00e2nd tiparele meteorologice globale.<\/p>\n

Climatologul Friederike Otto de la Imperial College London<\/span><\/span> avertizeaz\u0103 c\u0103 perioadele prelungite peste pragul de 1,5\u00b0C pot genera \u201eo gam\u0103 de fenomene extreme f\u0103r\u0103 precedent\u201d, iar multe ora\u0219e nu sunt preg\u0103tite.<\/p>\n

Ea subliniaz\u0103 \u00eens\u0103 c\u0103 El Ni\u00f1o este un fenomen natural temporar, \u00een timp ce \u00eenc\u0103lzirea global\u0103 se intensific\u0103 pe termen lung din cauza arderii combustibililor fosili.<\/p>\n

Cercet\u0103torii Copernicus Climate Change Service<\/span><\/span> continu\u0103 monitorizarea<\/a> pentru a stabili dac\u0103 acest nou maxim este temporar sau parte a unei tendin\u021be permanente.<\/p>\n","protected":false},"excerpt":{"rendered":"
